Perseus "Percy" Jackson is a demigod, son of the mortal, Sally Jackson, and the Greek god of the sea, Poseidon. Percy lives in the Upper East Side of Manhattan, but found his life uprooted upon discovering his true paternity. He has black hair and sea-green eyes. He has inherited special abilities from Poseidon which include the ability to control water, boats, and ships; to create small hurricanes; to breathe and see clearly underwater, and to talk to horse-like creatures and most aquatic animals. He is also a gifted swordsman using his shape-shifting sword pen named Anaklusmos (Ancient Greek for "Riptide") for battle. The pen was created by Zoë Nightshade, and when uncapped changes into a celestial bronze sword. If he loses it, it will always appear back in his pocket.
Percy struggles significantly in his mortal life. He, like most demigods, was diagnosed with ADHD and dyslexia. This made him the subject of bullying from his peers. His mother was once married to Gabe Ugliano (Smelly Gabe), an abusive, gambling-addicted alcoholic. His repugnant mortal odor masked Percy's demigod scent, hiding him from monsters. At the end of The Lightning Thief, Sally turned Gabe into stone using Medusa's head. Later, she marries Paul Blofis, whom she genuinely loves, and they have a daughter named Estelle. Percy begins dating Annabeth at the end of The Last Olympian.
Grover Underwood is a satyr and Percy's best friend. He appears in The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth, The Last Olympian, The Son of Neptune, The House of Hades, The Blood of Olympus and The Burning Maze.
He has curly reddish-brown hair and fur, acne, and a wispy goatee. His horns grow larger as the series progresses, and he must take increasingly careful measures to hide them and his goat legs while posing as a human. In The Lightning Thief, Chiron states that Grover is small even for his age: He is twenty-eight then, but because satyrs mature half the speed of humans, he is considered a teenager. Grover is quite sensitive and attached to nature. Like all satyrs, he can sense emotions and sense monsters and demigods. As the series progresses, his concern for his friends and the pursuit of his goals leads him to take on leadership roles and become more confident. Unlike his demigod friends, Grover is not an orthodox fighter. Instead, he uses reed pipes or a cudgel. In The Battle of the Labyrinth, Grover begins a relationship with the dryad Juniper.
In The Lightning Thief, he gets a "searcher's license" after delivering Percy safely, allowing him to search for the lost god Pan. When Polyphemus captures him in The Sea of Monsters, he activates an empathy link, a psychic bond with Percy created a year before that allows telepathic communication across great distances. He uses this to guide Percy to his rescue. At the end of The Last Olympian, he is named a Lord of the Wild and given a seat on the satyrs' ruling council, the Council of Cloven Elders.
In The Heroes of Olympus series, Grover mainly appears as one of Camp Half-Blood's satyr allies reporting on Gaea's rising and participating in negotiations with the Romans to get Reyna to help transport the Athena Parthenos statue across the world.
In The Dark Prophecy, Meg McCaffrey summons Grover after getting a prophecy stating that she and Apollo will need a satyr guide. In The Burning Maze, Grover guides the two through the Labyrinth and, alongside the other nature spirits, aids in their fight against Medea and Caligula. After the death of Medea and Helios fading from existence, ending the California wildfires that he was causing, Grover returns to Camp Half-Blood.
In The Chalice of the Gods, taking place between The Heroes of Olympus and The Trials of Apollo, Grover volunteers to join Percy's quests to get recommendation letters from the gods so that he can get into New Rome University. Grover uses his nature spirit connections to help search for Ganymede's chalice of immortality and then to help Percy sneak into Mount Olympus to return it to Ganymede in the midst of Zeus' brunch for his mother Rhea.
In the films, he is portrayed by Brandon T. Jackson and Bjorn Yearwood as young Grover in the second film. In the musical, he is portrayed by George Salazar. Aryan Simhadri portrays Grover in the TV series.
Annabeth ran away from her father and stepfamily at age seven and encountered Luke Castellan and Thalia Grace. They lived as runaways until they were found by Grover Underwood and taken to Camp Half-Blood. Thalia temporarily perished when they reached Camp Half-Blood. Annabeth remained attached to Luke and convinced of his goodness even after his decision to support Kronos. He was also her first love interest. Her attempts to bring Luke back into the fold are an important theme in the books.
At the end of the series, she plans to finish high school in New York and then attend college in New Rome, with her boyfriend, Percy Jackson. In The Hidden Oracle, one of her friends states that Annabeth had gone to Boston for "some family emergency" — searching for her cousin Magnus Chase.
At the end of The Trials of Apollo, Annabeth starts attending New Rome University with Percy after helping him in The Chalice of the Gods to get the godly recommendation letters that Percy needs.
Her main weapon is a short celestial bronze knife given to her by Luke Castellan. In The Last Olympian, it was found to be a cursed blade, which Luke used to eject Kronos from his soul, consequently killing himself. After losing it in The House of Hades, she uses a drakon-bone sword given to her by the giant Damasen in Tartarus. In The Kane Chronicles crossover series, she also uses Sadie Kane's wand when it turns into a dagger similar to the one Luke gave her. Annabeth also owns an invisibility Yankees cap, a gift from her mother. At the end of The Battle of the Labyrinth, Daedalus gives Annabeth his incredibly advanced laptop, which she loses in Tartarus in The Mark of Athena. In the third book of Magnus Chase series, Annabeth wears a UC Berkeley College of Environmental Design shirt, implying that is where she goes to college. Annabeth also has dyslexia and ADHD but is good at keeping it in check.
In the films, she is portrayed by Alexandra Daddario and Alisha Newton as young Annabeth in the second film. In the American musical, she was portrayed by Kristin Stokes. Leah Jeffries portrays Annabeth in the TV series.
Chiron
A centaur with a white stallion body[1] and a son of Kronos. He is Percy's mentor and the activities director at Camp Half-Blood. He is the mythological Chiron who was granted immortality by the gods for as long as he is needed to train heroes.
In The Lightning Thief, he first appears disguised as a Latin teacher at Percy's school, using an enchanted wheelchair to conceal his horse half.[2] Chiron is shown to suspect Percy's true heritage as a son of Poseidon and gives Percy his sword Riptide. After Percy is poisoned by Luke Castellan, Chiron heals him.
In The Sea of Monsters, due to Thalia's tree being poisoned, Chiron is blamed due to him being a son of Kronos and he is fired from camp. During Percy and Annabeth's quest into the Sea of Monsters for the Golden Fleece, they keep in touch with Chiron. After Percy tricks Luke into exonerating Chiron, the centaur arrives with the party ponies to rescue Percy, Annabeth, Grover and Tyson from the Princess Andromeda and he is present when Thalia is resurrected from her tree by the Golden Fleece.
In The Titan's Curse, Chiron tries to cheer Percy up without success after Annabeth's kidnapping. He has also started to favor Thalia due to her being the more likely prophecy child following her resurrection. Upon realizing that Nico di Angelo is actually the son of Hades, Percy decides to keep it from the centaur.
In The Battle of Labyrinth, Chiron becomes suspicious of the new sword instructor Quintus who later turns out to be Daedalus in disguise. He also organizes the quest into the Labyrinth and participates in the battle with a monster army invading from the maze. Although Chiron is badly wounded, he survives the fight.
In The Last Olympian, Chiron leaves Percy to lead the army of Camp Half-Blood while he gathers much needed reinforcements in the form of the party ponies. Chiron directly confronts his father Kronos in battle, although he's defeated. After Kronos' defeat, Chiron allows Rachel Elizabeth Dare into Camp Half-Blood to become the new Oracle of Delphi.
In The Lost Hero, Chiron recognizes Jason Grace as a Roman demigod, much to his alarm, but he refuses to tell the Greeks about the Romans due to swearing on the River Styx to keep the secret due to the historic rivalry between the two. With Dionysus having been recalled to Olympus which Zeus has closed off, Chiron is now in charge of camp. He eventually admits the truth about the Greeks and Romans after the quest to rescue Hera and the discovery of Bunker 9, but even Chiron doesn't know where the Roman camp is.
In The Mark of Athena, Percy and Annabeth manage to contact Chiron via a dream to warn him of the Roman legion's upcoming attack on Camp Half-Blood.
In The House of Hades, Leo and Calypso see the centaur in a vision preparing for battle.
In The Blood of Olympus, Chiron participates in the final battle with Gaea and leads a funeral alongside Nico for the campers who fell in the battle, both Greek and Roman. He later has several long conversations with Reyna and Frank Zhang about the newly established alliance between the two camps.
In The Hidden Oracle, six months later, Chiron is still in charge of Camp Half-Blood, and he is dealing with missing campers, down communications and the arrival of a now mortal Apollo. He later participates in the battle with Nero's automaton and gives the resurrected Leo Valdez a kick in the gut -- joining the campers who literally line up to hit Leo -- for scaring him with his sacrifice to destroy Gaea.
In The Tower of Nero, Chiron is away from camp when Apollo and Meg McCaffrey return months later to face Nero. Chiron returns in time to receive a message from Rachel summoning reinforcements from camp which Chiron personally leads, disguising it as a field trip for the youngest campers. Chiron is implied to have been meeting with Bast and Mimir about some kind of a threat that endangers the Greco-Roman, Egyptian and Norse pantheons, but he refuses to elaborate on what it is.
In The Sun and the Star: A Nico di Angelo Adventure, Chiron is left alone at camp with Dionysus, Nico and Will Solace when the vast majority of the campers decide to return home for the school year. Along with the wine god, Chiron reluctantly authorizes the two demigods to go on a quest to Tartarus to rescue Bob and greets them upon Nico and Will's successful return with the Titan.
In Wrath of the Triple Goddess, Chiron surprises Percy by becoming his substitute history teacher at Alternative High School, although Chiron explains that it's simply a coincidence. Wanting to simply be a teacher sometimes, Chiron got Percy's stepfather Paul Blofis to put him on the district's substitute list. Percy has recently learned that Chiron's wheelchair isn't just a disguise, but it's actually hard for the centaur to walk. Chiron was once shot in the leg by Hercules with a poisoned arrow, leaving the centaur with a permanent leg injury and in eternal agony, causing to Percy feel guilty for not having noticed it before. This story mirrors Chiron's death in mythology. Chiron provides Percy with information on Hecuba and is gone a few days later, much to Percy's disappointment. Paul later tells Percy that Chiron is due to teach his class the next week while Paul is on jury duty.
Chiron is played by Pierce Brosnan in the first film and by Anthony Head in the second film. In the musical, he is portrayed by Jonathan Raviv. In the TV series, he is portrayed by Glynn Turman with the character depicted with a leg brace on his left hind leg as the result of a war injury.
Luke Castellan
Luke Castellan was a 19-year-old son of Hermes and May Castellan. He appears in The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth and The Last Olympian.
Introduced initially as the friendly head counselor of the Hermes cabin, Luke is revealed to serve Kronos at the end of The Lightning Thief. He is resentful of his father, who adhered to the gods' policy of non-interference despite Luke's mother May Castellan's mental illness after her failed attempt to become the host of the Oracle of Delphi. Having had enough of his mother's "fits", Luke ran away from home at nine years old and eventually arrived at camp aged fourteen with Annabeth Chase and Thalia Grace. After the loss of Thalia, a failed quest and continued silence from Hermes, Luke's ongoing resentment turned into a strong hatred of his father and the other gods. Described as decent and kind before Kronos, he behaved with volatility and violence after his defection. Though Luke originally served Kronos willingly, the horrors he witnessed during the Battle of Manhattan convinced him to fight against his former master, eventually committing suicide to destroy the Titan, who was using Luke as his host, by stabbing himself in his Achilles Heel with a celestial bronze knife he had given to Annabeth when they first met. When he died, Luke reiterates what Ethan Nakamura had told Percy before: unclaimed children and unrecognized gods deserve more respect than they have been given. Percy later fulfills his request.
Luke is described as handsome, with sandy blonde hair, blue eyes, and a long scar on the side of his face, given to him by Ladon the Dragon during his failed quest. Besides the ability to open locks with his mind, which he inherited from his father, Luke is an excellent swordsman. He receives a sword named "Backbiter" from Kronos at the end of The Lightning Thief. It is later reforged as Kronos's scythe and has the ability to harm both mortals and immortals because of its double-edged blade, half steel, half celestial bronze. From Halcyon Green, he receives a diary he later entrusts to Chiron, and a celestial bronze knife he later gives to Annabeth with a promise to always remain her family. The knife becomes cursed after Luke's defection to Kronos. From his father Luke receives magic flying shoes, which he later curses and gives to Percy, but Percy gives the shoes to Grover. Just before giving himself over completely to host the spirit of Kronos, Luke bathes in the River Styx and obtains the invincibility of Achilles.
In the films, he is portrayed by Jake Abel and Samuel Braun as the young Luke in the second film. In the musical, he is portrayed by James Hayden Rodriguez. Charlie Bushnell portrays Luke in the TV series.
Thalia Grace
"Thalia Grace" redirects here. Not to be confused with Thalia (Grace).
Thalia Grace is the daughter of Zeus and Beryl Grace, a TV starlet. She is seven years older than her brother Jason Grace and appears in The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Last Olympian, The Lost Hero, The Blood of Olympus, The Dark Prophecy, and The Tyrant's Tomb.
Due to her mother's abusive nature, Thalia had considered leaving home since she was little, but stayed to protect Jason. When Jason was seemingly stolen during a visit to Sonora, Thalia finally ran away and stayed on the run with Luke and Annabeth until they met Grover the satyr when she was 12. When they reached camp, Hades sent a horde of hell hounds that Thalia held off, sacrificing herself for her friends. Zeus pitied his daughter and turned her into a pine tree; her spirit then provided a magical barrier around the camp, keeping mortals and monsters out. Seven years later, she is purged from the pine tree with the Golden Fleece, which was applied to save it from poisons that were destroying the magical barrier protecting the demigods. At the end of The Titan's Curse, she becomes the lieutenant of the Hunters of Artemis, which freezes her age the night before her 16th birthday and prevents her from being the child of the prophecy.
Thalia has bright blue eyes and short, spiky black hair, and wears black eyeliner and punk style clothing. Jason describes her as having a Mediterranean complexion. Annabeth and Chiron remark that her personality and character traits (like her bravery and loyalty) are very similar to Percy's. She also shares some traits with her father, such as his pride, confidence, and vehement reactions to betrayal or contradiction. An incredibly skilled warrior, she is willing to attack even Luke, who was known as the best swordsman of the last 300 years. Thalia's weapons are a replica of the shield Aegis, disguised as a silver bracelet, and a spear, disguised as a Mace can. After The Titan's Curse, she also uses a bow and hunting knives, given to her by the Hunters of Artemis. Her main power is the ability to summon lightning and generate electric shocks. In The Titan's Curse, it is revealed that she has a rather ironic fear of heights, despite being a daughter of Zeus. In The Lost Hero, she embraces her brother Jason for the first time in years, only to learn that he had lost his memory.
She is portrayed by Paloma Kwiatkowski and Katelyn Mayer as the young Thalia in the second film. In the TV series, she will be portrayed by Tamara Smart.[3]
Zoë Nightshade
In The Titan’s Curse, Zoë Nightshade is introduced as one of Artemis’ huntresses. She is described as looking around 14 years of age, although it is later revealed that she is well over 2000 years old. She is also later then revealed to be a former Hesperid, daughter of Atlas and Pleione. She appears in The Titan’s Curse, along with being mentioned in The Battle of the Labyrinth, The Son of Neptune, The Blood of Olympus, The Dark Prophecy, and being seen in a flashback in The House of Hades.
Zoë is described by Percy as being tall, graceful and gorgeously beautiful. She had brown eyes, slightly upturned nose and long dark hair braided with a silver circlet on the top. It is also stated by Percy that she gave him the impression of a Persian princess. Although her ethnicity or race is never specified, she is known to have copper-colored skin. She is said to have the same cold look in her eyes as her father, the Titan Atlas.
In her early life, Zoë gave Hercules tips on how to trick her father, helping him complete his quest on stealing the golden apple. She then gifted him her hairpin, which turns into "Anaklusmos", the sword currently in the possession of Percy. After her sisters had found out about what Zoë had done, they exiled her. This pained Zoë, knowing that the Hesperides were her only family. Ultimately, Hercules never gave Zoë any credit and eventually abandoned her. As a reaction, she came to hold a grudge against male Heroes, especially those who reminded her of Hercules.
After her incident involving Hercules, Zoë joins the hunters of Artemis, a group of eternal maidens who swears off men for semi-immortality and hunt with Artemis until they fall in battle. Zoë Nightshade eventually rose to become Artemis' loyal lieutenant for over 2000 years.
Zoë Nightshade makes it very clear that she dislikes Thalia Grace. Once had they ran into her, Luke Castellan, and Annabeth Chase. Zoë had asked Thalia to join the hunters, almost managing to convince her, but Thalia refuses, not wanting to leave Luke. Zoë was offended by her decision, which led them into a heated argument. This gave Thalia a strong hatred to the Hunters, especially Zoë Nightshade.
Throughout the book, Zoë talks in an Early Modern, or Shakespearean, English. She also is said to speak in an old, strange accent, more heavily when upset. She would use words like ‘thou’, ‘thee’, and ‘thy’, and got irritated when Thalia would correct her speech, exclaiming “I hate this language! It changes too often!”.
Zoë also showed particular interest and love for the stars. After her death, caused by Ladon attacking her and Atlas’ final blow, she is turned into a constellation by the goddess Artemis. However, before she passes onto the stars, Zoë apologizes to Thalia, telling her that they could have been sisters. She also addresses Percy, telling him that she is honored he carried "Anaklusmos".
Tyson
In The Sea of Monsters, Tyson is introduced as Percy's bullied, childish friend. When Percy is forced to take him to camp, it is revealed that he is a baby Cyclops and thus a son of Poseidon, making him Percy's half-brother. He appears in The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth, The Last Olympian, The Son of Neptune, The Mark of Athena, The Blood of Olympus and The Tyrant's Tomb.
Tyson is tall with unkempt teeth and fingernails, brown hair, and eyes. He is mentally about 8 years old but highly intelligent and compassionate. As a son of Poseidon, he shares some of Percy's powers. As a Cyclops, he is immune to fire and has super strength, an uncanny ability to mimic voices, enhanced senses, and understands the "old tongue" (the language spoken by Gaia to her first children). Tyson is close with several characters and magical creatures in the series, including Rainbow the hippocampus, the hellhound Mrs. O'Leary, and the harpy Ella, who eventually becomes his girlfriend.
In The Sea of Monsters, Tyson first appears as a huge homeless kid that is taken in as a class project by Merriweather Prep, Percy's school. Tyson is sensitive, childish, and bullied with Percy being his only friend. However, it's also suggested that Tyson's presence in Percy's life has shielded him from attack throughout the year as monsters are too afraid to attack Percy while he is with a Cyclops. When Laistrygonian giants attack in the guise of a dodgeball game, Tyson's powers as a Cyclops shield him from harm and level the playing field, allowing him to defeat several of the giants before Annabeth Chase intervenes to finish the job. Due to her own bad experiences with Cyclopes, Annabeth reluctantly takes Tyson with them to Camp Half-Blood where his immunity to fire proves to be vital in defeating the attacking Colchis Bulls. Annabeth reveals Tyson's true nature to Percy and the young Cyclops faces a great deal of prejudice from the other campers due to his monster heritage and frustration from Percy when Poseidon claims Tyson as his son, causing Percy to be bullied as well. The sole exception to the bullying is Charles Beckendorf whose father, Hephaestus, employs Cyclopes, causing Beckendorf to befriend Tyson and train him in metalworking. When Percy and Annabeth secretly leave on a quest for the Golden Fleece, they only reluctantly take Tyson along and he befriends the hippocampus Rainbow who transports them to the Princess Andromeda. While trying to enter the Sea of Monsters, Tyson is apparently killed when the CSS Birmingham explodes as Tyson is trying to fix the engine at time, the only one capable of withstanding the extreme heat. Tyson later resurfaces on Polyphemus' island, having survived the explosion before being rescued by Rainbow. Polyphemus calls Tyson his half-brother, but Tyson helps Percy defeat Polyphemus, rejecting the other Cyclops for his evil ways. After returning to camp, Tyson repairs and upgrades Percy and Annabeth's chariot for the second chariot race and provides them with weapons. His gift to Percy, a wristwatch that Tyson had spent the summer working on, turns out to be a shield that proves to be vital in their victory. Afterward, Tyson reveals to Percy that having faced a hard life of constant monster attacks, he had prayed to their father who had led Tyson to Percy. Having received an offer to work in Poseidon's underwater Cyclops forges, Tyson leaves on Rainbow, saddening Percy who has come to see the Cyclops as a true brother.
In The Titan's Curse, Percy stays connected with Tyson through Iris's messages, although Tyson's new job and Percy's own responsibilities make this somewhat difficult to manage. At the end of the book, Tyson reveals that he has gotten permission to take the summer off and return to Camp Half-Blood.
In The Battle of the Labyrinth, Tyson returns to camp and repairs Percy's wristwatch shield which had been damaged while fighting the Manticore months before. Tyson joins the quest through the Labyrinth to find Daedalus and is at first excited to meet his idol Briares who they rescue on Alcatraz Island. However, Briares had become depressed, as all of his siblings had perished and lost the will to live, disillusioning Tyson. When Grover sets off on a side quest to find the missing wild god Pan, Tyson decides to join him despite his nervousness and allergies around satyrs. Percy, Annabeth, Grover, Rachel, Nico, and Tyson are present when Pan fades from existence. Tyson takes part in the last battle with Kronos' forces. When Briares arrives to help, he credits Tyson with his decision to help and he calls Tyson the true Hero.
In The Last Olympian, Percy meets his brother again a year later when, after the destruction of the Princess Andromeda, he ends up in Atlantis. Although the city is under siege by the ocean gods allied with Kronos, Poseidon refuses to allow Tyson to fight, leading to an argument between him and Percy because Poseidon believes that Tyson is too young to fight and must instead be protected. When Poseidon arrives to help defeat Typhon, much to Percy's joy, Tyson is leading Poseidon's army of Cyclopes. Following the defeat of Kronos, Zeus commends Tyson's bravery by making him the General of the Cyclopes. Due to Tyson's preference for a club for a weapon, Zeus promises that the gods will find him a suitable club.
In The Son of Neptune, Tyson is shown to be searching for the missing and amnesic Percy. When Percy's memories begin to return and unable to Iris message any of his friends, Percy manages to contact Tyson through a dream. Percy instructs his brother to find Ella the harpy and to meet him near the Caldecott Tunnel. After his quest, Percy summons his hellhound Mrs. O'Leary at the tunnel and she arrives with Tyson and Ella, leading to an overjoyed Percy and Tyson reuniting. Ella comments on Tyson's bravery and Percy notices that his brother is blushing, causing Percy to tease him about the romance blooming between Tyson and Ella. Tyson takes part in the Battle of New Rome, effortlessly killing the Cyclops Ma Gasket and her children and also battling Earthborn spirits with the help of advice on their weak spots from Ella. After the battle, Tyson is present when Percy is made praetor of the legion and when the Roman Senate discusses the approach of the Greek demigods.
In The Mark of Athena, Tyson is still present when the Argo II arrives. After Ella issues a prophecy, Percy discreetly orders Tyson to take Ella away, not wanting Octavian to learn of the harpy's knowledge of the lost Sibylline Books. After things go south, Percy contacts Tyson and orders him to take Ella to Camp Half-Blood where the harpy will be safe.
In The Blood of Olympus, Tyson is mentioned to have brought in a few friendly Cyclopes to aid in Camp Half-Blood's defense. When Reyna, Nico and Coach Hedge are cornered by Michael Kahale, Leila and Dakota on a yacht near Camp Half-Blood, Tyson unexpectedly arrives to help with Ella, who is now his girlfriend, and Rainbow, using his ability to mimic voices to mimic Octavian and trick the Romans into disarming themselves. Taking advantage of the surprise, Tyson effortlessly knocks Kahale unconscious with a single blow to the head, which is notable because Kahale is said to be so strong that it takes someone with an immense strength to overpower him. Tyson brings Ella and Coach Hedge back to Camp Half-Blood on Rainbow and relays Reyna's message about her intention to come at sunrise. During the ultimate battle with Gaea, Tyson leads the friendly Cyclopes against the Earth goddess and her monster army. Afterwards, with the powers of prophecy no longer working, Tyson joins Ella and Rachel Elizabeth Dare in traveling to New Rome in the hopes of reconstructing the Sibylline Books, the only source of prophecies left at the moment.
In The Tyrant's Tomb, Tyson and Ella have settled in New Rome where the harpy has been using her photographic memory to reconstruct the lost Sibylline Books while the harpy and the Cyclops run a bookstore at the same time. Ella's transcriptions take the form of tattoos on Tyson's skin rather than being put on paper, something that Apollo finds to be awkward to deal with. Tyson also has his girlfriend give him a tattoo of his friend Rainbow. Tyson and Ella help Apollo (Lester) to decipher the prophecies surrounding the current threat from Caligula, Commodus and Tarquin and later to perform a ceremony to summon Diana for help against the emperors and Tarquin's undead legion. The two are still in Diana's temple when Tarquin attacks their bookstore, looking for the Sibylline Books. After the battle, Tyson and Ella rename the bookstore Cyclops Books and provide Apollo and Meg with the first part of a new prophecy that directs them to return to New York City to face Nero.
Nico is first seen in The Titan's Curse, as an unclaimed demigod rescued by Percy, Annabeth, Thalia, and Grover. At the end of the novel, it is revealed that Nico is a son of Hades. He appears in The Titan's Curse, The Battle of the Labyrinth, The Last Olympian, The Son of Neptune, The Mark of Athena, The House of Hades, The Blood of Olympus, The Hidden Oracle, The Tower of Nero and The Sun and the Star, of which he is one of two main protagonists (the second being his boyfriend Will Solace.)
Despite biologically being ten years old when first introduced, he and his elder sister Bianca were born in the 1930s. After Zeus killed their mother Maria while trying to kill the children, Hades wiped their memories and placed them in the Lotus Hotel by the fury Alecto, a place in Las Vegas where time stands still for decades before he and Bianca were removed from the Lotus Hotel by Alecto, who brought them to the military academy Westover Hall.
He is native to Venice, Italy and can speak Italian (as his native language). Nico is initially depicted as cheerful and childlike, with olive skin and dark hair. He enjoyed playing Mythomagic, a mythology-themed card game similar to Magic: The Gathering. He takes the death of Bianca very hard, becoming moody, secretive, and irritable. He becomes angry at Percy, who swore to protect Bianca, but later forgives him. Afterward, he lived in the Underworld with Hades, where he becomes pale and shaggy-haired and begins wearing dark clothing. Nico, despite being very powerful, is extremely lonely, much like his father. He makes nearby people uncomfortable, partially due to his weapon of choice: a sword made of iron cooled in the river Styx ("Stygian iron"), capable of absorbing monsters' essences rather than banishing them to Tartarus. Stygian iron, unlike celestial bronze and Imperial gold, can harm both mortals and immortals.
In The Mark of Athena, he is captured by the giants Ephialtes and Otis to be used as bait before being rescued. In The House of Hades, Nico keeps a promise to Percy to guide the Seven to the mortal world side of the Doors of Death. Nico is outed as homosexual to Jason Grace by Cupid and is revealed to suffer from internalized homophobia due to growing up in the 1940s. After Cupid outs him, Nico admits his long-standing feelings for Percy to Jason. Although Jason offers Nico support, he is rebuffed. During Percy and Annabeth's time in Tartarus, they are helped by Bob the Titan who was convinced by Nico that Percy is a good friend. After Percy and Annabeth escape Tartarus thanks to the aid of both Bob and the Giant Damasen, Percy reunites with Nico and attempts to reconcile with him, but fails. During The Blood of Olympus, Nico, with the help of Reyna Avila Ramirez-Arellano and Gleeson Hedge, transport the Athena Parthenos to Camp Half-Blood. At the end of the novel, he fully reconciles with Percy and admits his feelings for him, although he notes that he no longer has those feelings anymore and the two depart as friends. During the events of Heroes of Olympus, he developed feelings for Will Solace, son of Apollo, who becomes his boyfriend between the events of The Blood of Olympus and The Hidden Oracle. As revealed in The Sun and the Star, Will developed an interest in Nico while Nico was helping him in the infirmary, and Nico in turn fell for Will when he helped Nico deal with his anger over the death and resurrection of Leo Valdez. Subsequently, an attempt by Nico to ask Will out during a private picnic turned into a camp-wide coming out party for Nico due to a misunderstanding. Deciding to come out rather than continue hiding, Nico publicly asked out Will, who accepted while none of Nico's worst-case scenarios surrounding coming out happened, giving him more confidence. Nico later realizes that his homophobia comes from a bad reaction that he got from a friend while he was eight in the 1940s.
Nico’s suggestion that Percy take on the curse of Achilles and his work to convince Hades to fight in The Last Olympian is crucial to the Olympians' success and earns him a short bout of fame. He is privy to the fact that there are two camps, one Greek and one Roman, before The Lost Hero, making him an important liaison between the two groups in the latter series. He brings his half-sister Hazel back from the dead and establishes her at Camp Jupiter. At the end of The Son of Neptune, Nico travels through Tartarus to find the monstrous side of the Doors of Death, an experience that leaves him haunted and weak. In The Blood of Olympus, he nearly dies several times while "shadow-traveling", which involves melting into shadows and teleporting himself to different places. His sister, Hazel Levesque, whom he brought back from the dead, is the daughter of Hades' Roman counterpart Pluto. In The Hidden Oracle, Will Solace introduces him as his boyfriend to Apollo. Although their attraction for each other is hinted at in The Blood of Olympus, they are not seen getting together. After the three-legged death race, he is seen assisting Will to treat the injured patients. At the end of the book, he helps Apollo and the others fight after his and Will's canoe capsized. In The Tower of Nero, he and Will help to fight Nero and Nico is shown to have become depressed following the death of Jason Grace. At the end of the book, Nico is convinced that his friend the Titan Iapetus or 'Bob' is calling for help from Tartarus despite his apparent death in The House of Hades. Nico decides to try to find out what happened to the friendly Titan with Will's help and rescue him if need be.
In The Sun and the Star, two months after The Tower of Nero, Rachel Elizabeth Dare gives Nico and Will the prophecy for their quest to Tartarus for the twelfth time, prompting Nico to convince a reluctant Chiron to give them an official quest. Nico and Will enlist the help of the troglodytes, or "trogs", whom Nico had relocated to the Underworld following the events of The Tower of Nero, to sneak into Tartarus without Hades' knowledge. Impressed by their success, Menoetes reveals that Bob has been captured by the primordial goddess of night Nyx who has been trying to force Bob to become Iapetus again. Nico finally reveals the story of his first trip into Tartarus and his encounter with Nyx, who grew interested in the young demigod due to his internal darkness. The trogs subsequently lead Nico and Will to the River Acheron, where the nymph Gorgyra agrees to help them in exchange for Nico and Will sharing their story with her (two of the story's being how they got together and the first kiss.) The demigods use Gorgyra's canoe to ride the Acheron into and through Tartarus, but the river's power forces them to confront their insecurities and differences of opinion, particularly Will's negative opinion of the Underworld which Nico sees as his second home. After finding Bob's pet saber-toothed cat Small Bob, the demigods finally locate the Titan in Nyx's home, the Mansion of Night, and free him from a continuous regeneration cycle by combining their powers of light and dark. Confronting the group, Nyx attempts to convince Nico to give into his darkness and to stay in Tartarus, revealing that she has created cacodemons out of that darkness. Fighting back against Nyx's manipulations, Nico gives the cacodemons their freedom, literally letting go of his demons in the process and convincing Nemesis, Hypnos and Epiales to help them escape, the cacodemons choosing to accompany them. While leaving the underworld, Bianca and Maria visit him in his dreams, urging him to enjoy his future with Will and find happiness. Returning to Camp Half-Blood, Bob departs to figure out his future while Nico decides to adopt the cacodemons, renaming them Cocoa Puffs.
Rachel Elizabeth Dare
Rachel is a mortal girl who can see through the Mist, the force that obscures gods and monsters from most mortals. Her father, Walter Dare, is a rich businessman, a fact which she is rather averse to. She first meets Percy in The Titan's Curse at the Hoover Dam. In The Battle of the Labyrinth, she guides Percy through the Labyrinth to Daedalus's workshop. It is hinted that she has some romantic feelings for Percy (which are noticed by Annabeth, who becomes extremely jealous). In The Last Olympian, she has strange visions about the war. Later, after she talked to Chiron, she decided to become the new Oracle of Delphi, according to her fate. She gave up her feelings for Percy to her duty. Her appearance makes things easier for both Olympians and Greek demigods.
Her first act as the Oracle is to deliver the next Great Prophecy, setting the plot of the Heroes of Olympus series. She is contacted in The House of Hades to ask for Reyna's assistance to bring the Athena Parthenos back to Camp Half-Blood.
Following the loss of Delphi to Python, as revealed in The Hidden Oracle, Rachel stops visiting camp and begins a frenzied attempt to regain her foresight, not helped by Apollo's disappearance. Once informed of Apollo's arrival, Rachel returns and learns that not only Delphi is lost, but also three other Oracles, and that only Rhea's Dodonian Oracle is still valid. She becomes upset upon learning of the existence of other Oracles, as Apollo hasn't told her before. In The Tower of Nero, Rachel regains her powers of foresight after Apollo kills Python and helps him battle Nero. She plans to take the summer off before returning to work as the Oracle full time. She also provides Nico and Will with a prophecy.
In The Sun and the Star, two months after regaining her powers, Rachel has been forced to repeat her prophecy for Nico and Will's quest twelve times until they actually leave on it. It's later revealed that Hades had sent Nico the prophecy through Rachel so that Nico would rescue Bob.
She has red hair and freckles, is skilled at painting and drawing, and occasionally shown as a non-ADHD foil for her demigod teammates. Percy remarks on her ability to stand still for a long time at a charity event. Due to her power of foresight, Rachel knows a great deal of knowledge before she learns it herself.
Clarisse La Rue
Clarisse is a daughter of Ares and the former lead counselor of the Ares cabin at Camp Half-Blood. She is hot-tempered, courageous, strong, an incredible fighter (usually using an electric spear given to her by Ares), and a good military strategist. She can be stubborn and overconfident, much like her father. Despite their similarities, Clarisse has a fear of her father and his anger at her if she should ever disappoint him. This, along with a strong sense of honor and pride, often motivates her actions. She also fears the Labyrinth because of what happened to her boyfriend Chris Rodriguez before she saved him. She is aggressive towards most demigods, including Percy, though she does respect and make friends with a few, including Percy, Annabeth, and Silena Beauregard.
Clarisse makes frequent appearances throughout the novels, first seen just after Percy arrives at camp. In The Sea of Monsters, Clarisse is given the quest to find the Golden Fleece. She is a main character in the short story "Percy Jackson and the Stolen Chariot" (published in The Demigod Files). In The Last Olympian, Clarisse initially sits out the war for Olympus due to a personal feud. Enraged after the loss of her friend Silena, she later joins the battle with a fury reminiscent of her father's, slaying a drakon singlehandedly and receiving the blessing of Ares. In The Blood of Olympus, Clarisse leads the Greeks in battle to defend the camp. In The Hidden Oracle, it is stated that Clarisse has gone to attend the University of Arizona and her role as counselor is taken by her half-brother Sherman Yang.
She appears in The Lightning Thief, The Sea of Monsters, The Battle of the Labyrinth, The Last Olympian, The Mark of Athena, The House of Hades and The Blood of Olympus.
In the film adaptations, she is portrayed by Leven Rambin. In the musical, she is portrayed by Sarah Beth Pfeifer. Dior Goodjohn portrays Clarisse in the TV series.[5]
Will Solace
Will Solace is a son of Apollo who is a native of Austin, Texas and the son of country singer Naomi Solace. While initially a recurring character in Percy Jackson and the Olympians and The Heroes of Olympus, Will becomes a main character in The Trials of Apollo and The Sun and the Star. He is stated to be the camp's best combat medic and runs the infirmary. According to Will himself, he lacks the archery skills of the other children of Apollo due to his inherited gifts being for healing rather than combat. Nevertheless, he is extremely brave and, along with his healing abilities, can emit a painful ultrasonic whistle and can glow. Will later discovers the ability to project rays of light from his body as an attack, channel his light through Nico di Angelo's sword to strengthen it and, by channeling his own darkness, Will can tap into Apollo's plague powers to make his enemies sick. Will is bisexual as revealed in The Sun and the Star.
Although unseen or at least unidentified, Will is present during the events of The Titan's Curse and The Battle of the Labyrinth as revealed in The Sun and the Star. As a result, he may be one of the unnamed Apollo campers mentioned during The Lightning Thief and The Sea of Monsters as well. Will reveals that, during the events of The Titan's Curse, he was training to be a field medic under his older brother Michael Yew and met Nico for the first time while treating his injuries after a training mishap.
In The Last Olympian, when Annabeth is hurt, Will uses his healing powers to help cure Annabeth. Following the death of his half-brother Michael Yew in the Battle of Manhattan, he becomes the head of the Apollo cabin.
In The Lost Hero, Will is assigned by Annabeth to show around recently arrived demigods Leo Valdez, Piper McLean and Jason Grace. Despite being properly introduced to Will, Leo refers to him as "the archer dude." Will also complains about Annabeth wrecking the Apollo Cabin's flying chariot.
In The Blood of Olympus, Will attends a head counselor meeting discussing the situation with Romans where he laments that he lacks the combat skills of many of his siblings due to his gifts being for healing. However, Chiron reassures Will that he will nevertheless play an important role due to the inevitable need for healers. At one point, Will calms down Clarisse by touching her arm, which Nico, witnessing the meeting through a dream, notes is an incredibly rare thing, as Clarisse would normally attack anyone who ever dared tried to do such a thing. Will delivers Coach Hedge's baby boy Chuck and, despite not being a fighter, volunteers to join the team sent to scout out the Roman positions to get a break along with Lou Ellen and Cecil. Will is reunited with Nico and the two begin bickering over Nico's use of his powers, which Will can sense are having a negative effect on his health. Will also berates Nico for his plan to leave both camps after the war, stating that there are people who are or would like to be Nico's friends if he would only give them a chance. The team sabotages the Roman onagers and Will uses his ultrasonic whistle twice to help defeat attacking enemies. During the final battle with Gaea's forces, Will and Nico confront Octavian who, being a Roman descendant of Apollo, is a distant relative of Will's, although Nico notes that compared to Will, Octavian is watered-down and unhealthy looking, lacking anything that makes a child of Apollo special. Although Nico and Will both see that Octavian's robes are caught up in the firing rope of the onager, Nico convinces Will not to intervene, leading to Octavian inadvertently launching himself to his death when he fires the weapon at Gaea. In the battle's aftermath, Nico avoids Will, convinced that the son of Apollo will now see him as a monster and want nothing to do with him, Nico having shown signs of a possible attraction to Will while working together on the battlefield. To Nico's surprise, Will forcefully tracks him down and orders Nico to spend three days in the infirmary recovering, berating Nico for avoiding him in the process. Nico comes out to Percy and admits his former crush on him before joining Will.
In The Hidden Oracle, Nico and Will are shown to have started dating each other in the six months since the battle. When Will's now-mortal father Apollo arrives at camp, Will and Nico aid Apollo in his quest and in adjusting to being mortal. After the battle with Nero's forces, Will treats the worst of the camp's cases of hay fever caused by Apollo's plague arrow.
In The Tower of Nero, Nico has become depressed following the death of Jason Grace on top of all of his other losses while Will is supportive and concerned for his boyfriend. During the final battle with Nero, Nico and Will help Apollo alongside the troglodytes, with Will at one point suddenly arriving with Camp Half-Blood reinforcements, as Nero apparently has the upper hand. Following Nero's death, Will coordinates treating everyone's injuries and helps Apollo prepare for his final battle with Python. Two weeks later, Apollo, now a god once again, visits his son and his boyfriend, and the two reveal that Nico believes that a voice that he's been hearing calling for help from Tartarus is Bob. Will plans to join Nico on his mission into Tartarus to try to find out what happened to Bob and to rescue him if he can, enlisting the help of the troglodytes to get in and out. Rachel provides them with a prophecy.
In The Sun and the Star, two months after receiving their prophecy, Nico and Will are the last kids at camp after all of the other demigods, including the year-rounders, choose to leave to see the world or to be with their mortal families at the end of the summer. Rachel arrives to repeat her prophecy for what turns out to be the twelfth time and Nico convinces a reluctant Chiron to give him and Will an official quest to rescue Bob. The quest brings up the problems with Nico and Will's relationship, particularly due to the effects of the River Acheron on the two demigods. Will is shown to be uncomfortable with the Underworld in general which irks his boyfriend due to Nico seeing it as his second home, although Nico helps Will to get a new perspective on it. In addition, Will is weakened over time by being so far from his father's domain of the sun. While telling stories to Gorgyra in exchange for her help, Nico and Will reveal the story of their relationship, including the fact that it was Nico who made the first move in what was intended to be a private picnic with the help of Juniper and the dryads but was turned inadvertently into a public coming out party. Throughout the quest, Will learns how to use his powers more offensively, using his powers over light to emit rays from his body that kills Epiales and singes Nyx's wing. Will is also able to tap into Apollo's plague powers and give Nyx a case of hay fever. By channeling his light through Nico into his sword, Will is able to make the weapon more powerful. They succeed in rescuing Bob and his pet Small Bob from Tartarus and return to Camp Half-Blood.
Calypso
Calypso is the daughter of the Titan Atlas, who is imprisoned on the island of Ogygia for supporting her father during the first Titan war.[6] She first appears in The Battle of the Labyrinth, where she nurses Percy back to health. She falls in love with Percy and is heartbroken when he has to leave. Percy asks the gods to release her at the end of The Last Olympian,[7] but she is still residing there when Leo becomes trapped on Ogygia in The House of Hades, having been released from the curse of being forced to fall in love with all those to fall upon the island rather than the island itself. Leo and Calypso subsequently fall in love legitimately. After Leo escapes, he swears on the River Styx that he will return for Calypso. At the end of The Blood of Olympus, Leo gets back to Ogygia and frees Calypso using an astrolabe that Odysseus had built for that purpose, although he was unable to complete it without a crystal from the island that Calypso had given to Leo on his first visit.
In The Hidden Oracle, Calypso comes to Camp Half-Blood with Leo and reveals that, due to her choice to leave Ogygia, she has become a mortal. She accompanies Leo and Apollo in the latter's quest to find the Oracles and stop the Three Emperors from conquering North America. Despite this, the two secretly attempt to find a normalcy for their lives and later announce to Apollo that they are going to settle in Indianapolis, although they will continue to help him anyway they can. At the end of The Dark Prophecy, Calypso stays at the Waystation, while Leo goes to warn Camp Jupiter of an impending invasion and Apollo travels with Meg to search for the Erythraean Sybil. During The Dark Prophecy, Calypso regains her ability to use magic, although the goddess Britomartis suggests that she had simply lost control of her powers rather than losing them altogether. With training from Josephine, Calypso begins regaining control over her magic.
As a sorceress, Calypso can command wind spirits to do her bidding. She loses most of her control of them when she gives up her immortality; however, she is still capable of summoning them to a degree, though by consuming more power than usual. Also, due to spending a long time at Ogygia, she has mastered sewing and lock-picking, which she uses while finding the gryphons at Indianapolis Zoo. She is Leo's girlfriend as of The Blood of Olympus, The Hidden Oracle, The Dark Prophecy, and The Burning Maze. In The Tower of Nero, Leo reveals that Calypso is enjoying attending high school and is currently working as a counselor at a mortal band camp for kids. The two are currently in a fight due to Leo's disrespectful behavior towards women, but both Leo and Reyna are sure that they will work it out when she returns at the end of the summer.
Bob
Iapetus, also known as Bob the Titan, is the Lord of the West and the father of Atlas. Bob first appears as one of the main antagonists of the short story Percy Jackson and the Sword of Hades which appears in The Demigod Diaries as well as the back of the paperback edition of The House of Hades. He subsequently appears as a main character and a supporting protagonist in The House of Hades and The Sun and the Star.
In Percy Jackson and the Sword of Hades, demigod Ethan Nakamura uses the sword of Hades to release Iapetus from where he has been locked in Tartarus for millennia. Iapetus battles Percy Jackson, Nico, and Thalia Grace, proving to be more than a match for them. In desperation, Percy throws Iapetus into the River Lethe which erases the Titan's memories, leaving him with a childlike personality. Percy convinces the amnesic Iapetus that he's actually their friend Bob and Bob heals Percy's injuries from the fight and aids him in confronting Persephone over her secret creation of the sword in the first place. Bob is subsequently employed as a janitor in the Underworld by Hades.
In The House of Hades while trapped in Tartarus, Percy and Annabeth briefly reminisce about Bob, inadvertently summoning him to their aid when the Titan overhears them. Percy is left feeling guilty after learning how Hades and Persephone used Bob as a servant while Nico would visit and tell the Titan about how good of a friend Percy is. Bob acts as a guide and protector to Percy and Annabeth, his knowledge of Tartarus from his time trapped there proving vital in their quest to reach the Doors of Death and escape. However, the regenerative effects of Tartarus on monsters starts to heal Bob's mind and slowly restore his memories, including the fact that Percy was the one who erased them in the first place. On one occasion, the group faces monsters who cast curses upon them that their previous enemies have left. Bob hesitates to help until Percy apologizes for his actions and for being a bad friend. Bob also befriends Small Bob, a sabertooth cat inadvertently created and then destroyed by Atlas in The Titan's Curse. Bob leads Percy and Annabeth to the friendly giant Damasen who heals the two demigods' injuries, but is convinced that he can't change his fate of forever battling the maeonian drakon despite Percy and Annabeth's belief that the line of the Prophecy of Seven about "foes bare arms to the Doors of Death" refers to the four of them: two demigods, a Titan and a Giant who should be mortal enemies under normal circumstances. Ultimately, despite the return of his memories, Bob takes Percy's advice to heart that he should take the parts of Iapetus' past that he wants while leaving everything else behind and continues to side with them, showing disgust for his evil past. At the Doors of Death, firmly identifying himself as Bob rather than Iapetus, he faces off against the embodiment of Tartarus alongside Small Bob, Damasen and the drakon, to ensure Percy and Annabeth's escape from the realm and the closing of the Doors of Death. The four are presumably destroyed in the process, devastating Nico, Percy and Annabeth who recognize Bob as a true friend. Percy sadly fulfils Bob's last request to say hello to the stars for him, Bob having wanted to see the stars again.
In The Tower of Nero, Nico begins hearing a voice calling out to him for help from Tartarus. Nico later reveals to Apollo that he believes that the voice is Bob, suggesting that the Titan had in fact survived his battle with Tartarus at the Doors of Death. Feeling guilty for leaving Bob behind, Nico is determined to travel into Tartarus and try to find out what happened to Bob and if possible, to rescue his friend. Nico and his boyfriend Will Solace explain that they intend to enlist the help of the troglodytes who are capable of safely tunneling into and out of anywhere, even Tartarus. However, Rachel issues them a prophecy that Will admits doesn't sound good.
In The Sun and the Star, he is rescued from Tartarus by Nico and Will. Having been killed fighting Tartarus, a reforming Bob was captured by Nyx who stuck the Titan in a permanent regeneration cycle. Nico and Will locate Bob's regeneration pod in the Mansion of Night and cut him out by combining their powers together. The reformed Bob joins the demigods in fighting against Nyx and her monster army before they make their escape. While the demigods rest, Bob sails them up the River Acheron, through the Underworld, out into Long Island Sound, and finally to the shores of Camp Half-Blood itself. In a dream, Hades reveals to Nico that he had sent his son the prophecy so that Nico would rescue Bob. Upon reaching Camp Half-Blood, Bob rejects an offer to stay and instead decides to head west with Small Bob.
Introduced in The Heroes of Olympus
Reyna Avila Ramírez-Arellano
Reyna Avila Ramírez-Arellano (also known by her initials RARA) is a 16-year-old Puerto Rican demigod. She is a daughter of Bellona, a Roman goddess of war, and the younger sister of Queen Hylla of the Amazons. She and her sister worked for Circe during the events of The Sea of Monsters where Reyna was one of the attendants who looked after Annabeth. After Percy and Annabeth escape and free Blackbeard and his crew, Reyna and Hylla were captured by the pirates before eventually escaping and going their separate ways.
Reyna found the way to Camp Jupiter, where she belonged. She became the praetor of the Twelfth Legion just four years after she joined. She would not trust anyone so easily, which was a good quality because she had a whole legion to lead. She did everything she could for her friends and family, which was everyone in New Rome. When she found out about the Greek demigods, Reyna chose not to pursue revenge against the Greeks, despite her difficult history with them. She understands the importance of both camps united.
She does not have a fatal flaw, unlike Annabeth. However, she could still not get everything she wanted. She could not find love, just like Venus had said. In the Tyrant's Tomb, she joined the Hunters. It is a sign of her overcoming fate, and living beyond other's expectations.
She is described as intimidating and a natural leader; she has glossy black hair and very dark brown eyes. Reyna is generally more used to responsibility than other demigods, as she is a praetor at Camp Jupiter.[8] Reyna's demigod ability is the power to lend her energy, skills, and character traits to nearby demigods. Similar to Leo Valdez, she can speak English, Latin and Spanish. Reyna is often accompanied by two magical dogs, Aurum and Argentum, or by her pegasus Scipio ("Skippy" dies after their trip from New York to Greece in The House of Hades after being slashed by a griffin's poisonous claw).[9] The immortal winged horse Pegasus awards her the title of "Horse Friend" because of her kindness towards Scipio and his descendants.
In The Blood of Olympus, she, Nico, and Coach Hedge go on a quest to return the Athena Parthenos to Camp Half-Blood. While shadow-travelling to New York, the trio stops in San Juan and visits Reyna's former house, haunted by the ghosts of her relatives. There Reyna reveals that the Ramírez-Arellano family (which includes Roberto Cofresi and Captain Marion Frederic Ramírez de Arellano) has always been favored by Bellona. Reyna's father (an Iraq War veteran) deeply loved the goddess, but his PTSD turned this love into an unhealthy paranoia. When Reyna was ten years old, he became a mania, or an evil insane ghost. When the mania attacked Hylla, young Reyna picked up the closest weapon and killed what remained of her father. Reyna is reluctant to discuss the incident because patricide is "unforgivable" in New Rome.[10] Reyna was in love with Jason Grace, which is shown throughout the series. Several characters like Percy, Annabeth, Piper, and Hazel have noticed Reyna's romantic feelings for Jason. In The Mark of Athena, Annabeth noticed that Reyna had a hungry sort of gleam in her eyes when she reunited with Jason Grace. Eventually, Annabeth sensed that Reyna wanted Jason to love her back. In The House of Hades, Jason felt guilty for letting her believe they had a future together. In The Blood of Olympus, she daydreams about romantic activities with Jason like "romantic walks" and "sunset picnics". When Jason had disappeared for 6–8 months, she briefly considered Percy a romantic partner.
In The Tyrant's Tomb, Reyna is revealed to be asexual and has always felt pressured to take a romantic partner, but didn't understand why she never truly felt an attachment to anyone until Apollo hits on her. Following the Battle of San Francisco Bay, Reyna resigns as praetor and instead joins the Hunters of Artemis. In The Tower of Nero, after becoming a god once again, Apollo encounters Reyna who is settling in well with the Hunters and has been mentoring Leo Valdez in his behavior towards Calypso.
Leonidas "Leo" Valdez
Leonidas "Leo" Valdez is a son of Hephaestus. He likes to joke around and relies on his sense of humor to bury the pain he feels as a result of his troubled past. He is described as having curly brown hair, brown eyes, a cheerful face, a slim and scrawny build, dark skin, and a mischievous smile. He is Hispanic-American and speaks Spanish. Leo has the ability to create and manipulate fire, a skill that no child of Hephaestus has had for 400 years. He also has severe ADHD, even by demigod standards. He is an excellent mechanic and at one point repairs a bronze dragon running wild in the camp's woods, which he names Festus (Latin for "happy"). Inspired by a blueprint in Bunker 9, an abandoned bunker in the camp's woods, and a picture he drew in his kindergarten time, he also creates the Argo II, the flying ship the seven demigods of the Great Prophecy sail on to reach Greece.
When Leo was eight, Gaia tricked him into burning down his mother Esperanza's machine shop in Houston, resulting in her death. Leo's remaining family blamed him for killing her and left him a foster child and runaway. He meets Piper McLean at the Wilderness School in Nevada. Later, in The Lost Hero, he meets Jason Grace, who wakes up on a school bus headed to the Grand Canyon with no memories. However, Leo and Piper have Mist-induced memories of meeting and becoming friends with Jason. He sometimes thinks of himself as a seventh wheel, as for the first three books of the Heroes of Olympus series, he is the only person aboard the Argo II without a significant other, though he proves no less important or skilled than the others. In The Mark of Athena, Hazel learns her former boyfriend, Sammy Valdez, was Leo's great-grandfather. Until he falls in love with Calypso, a nymph third-generation titanness, in The House of Hades, Leo flirts with almost every girl he meets to cover up his insecurities about never finding love. In The Blood of Olympus, Leo sacrifices himself to annihilate Gaia and dies in the process, but is brought back to life using the Physician's Cure and returns for Calypso on her island, Ogygia. This is an impressive feat, as nobody has ever been to Ogygia twice. However, Leo had the advantage of an astrolabe that had been created for just such a purpose by Odysseus as an old man. Leo had gotten the device from two dwarfs shortly before landing on Ogygia and had learned from them that Odysseus had lacked a vital crystal to complete the device which Leo had convinced Calypso to give him before leaving the island.
He and Calypso then journey back to Camp Half-Blood, sending a magic scroll ahead to let his friends know he's alive. When he does arrive at camp (at the end of The Hidden Oracle), everyone lines up to punch him for keeping them worried for so long. As Leo is included in the prophecy of the Grove of Dodona, he and Calypso accept the task to accompany Apollo on his quests in The Dark Prophecy. Afterward, he announces that he and Calypso will be living at the Waystation and leading an ordinary life. When the prophecy of Trophonius requires that someone must warn Camp Jupiter of an invasion, Leo does the task alone. He returns, but later learns of Jason's death. In The Tower of Nero, Apollo encounters Leo briefly while visiting the Waystation after becoming a god once again.
Festus
Festus is a mechanical dragon made decades ago by the Hephaestus cabin at Camp Half-Blood, and given wings by Leo Valdez years later. He was first encountered in The Bronze Dragon where Festus goes on a rampage before being shut down by Percy, Annabeth and Charles Beckendorf who intends to reprogram Festus to help defend the camp.
In The Lost Hero, Festus has gone out of control ever since Beckendorf's death, but Leo's immunity to fire allows him to corral and tame the bronze dragon. Festus transports Jason, Piper, and Leo, before being destroyed by a crash-landing at King Midas' mansion. Leo asks Hephaestus to take his head to Bunker Nine at Camp Half-Blood, where he later repairs him to be the figurehead on the Argo II. Festus acts in this role throughout The Mark of Athena and The House of Hades, acting as the ship's control interface and occasionally helping to defend against attacks. After Piper uses charmspeak on him, Festus is stated to be constantly active, and he is described as being more alive than ever. Although Festus was initially damaged beyond any hope of repair due to his control disk being destroyed in the crash landing, Leo is able to build him a new control disk using the works of Archimedes that he had recovered in The Mark of Athena.
In The Blood of Olympus, Festus is secretly rebuilt by Leo and plays a vital role in the defeat of Gaea, lifting the primordial goddess high in the air where she's weaker and holding Jason and Piper steady as Piper charms the goddess to sleep. After Gaea's defeat, Festus resurrects Leo with the Physician's Cure and helps him to rescue Calypso using a mariner's astrolabe created by Odysseus.
In The Trials of Apollo, Festus acts as one of Apollo's allies. In The Hidden Oracle, after traveling the world with Leo and Calypso for six months, Festus finally returns them to Camp Half-Blood with the help of a homing beacon created by Leo's little brother Harley. He is destroyed again in The Dark Prophecy by Commodus while defending the Waystation, but is easily rebuilt by Leo who had redesigned Festus in case of such an eventuality. In The Burning Maze, Festus transports Leo to Camp Jupiter to warn them of an upcoming attack and is mentioned to have helped to defend the camp. He later brings Leo to see Apollo, Meg and Piper in the aftermath of the events in the Labyrinth. In The Tower of Nero, Leo mentions that he's using Festus as his workshop while Leo teaches homeless kids shop skills. Although most of the kids only see Festus as a large vehicle, a few can see through the Mist and see Festus in his true form.
Piper McLean
Piper McLean is a daughter of Aphrodite and the famous actor, Tristan McLean. She is fifteen in The Lost Hero. Unlike most children of Aphrodite, Piper is not particularly concerned with beauty or fashion. Piper is Cherokee on her father's side. She has tan skin, eyes that change color constantly, and choppy chocolate-colored hair which she cuts herself. Her demigod powers include "charmspeak" (essentially, magical persuasion) and the ability to speak French, as it is "the language of love". She is also occasionally able to see visions in her magic dagger Katoptris (Ancient Greek for "mirror"), which once belonged to Helen of Troy. The dagger lost that power after the battle against the giants in Athens.
Piper's relationship with her father is mutually affectionate but strained, in part because of the small amount of attention he spares for her. When she was young, Piper used her persuasive skills to "borrow" (ask for in charmspeak) things to earn a little of his time. After he is kidnapped by the giant Enceladus in The Lost Hero and subsequently rescued by Piper, Jason, and Leo, Mr. McLean's relationship with his daughter begins to improve. Piper is also very close to Jason. Though she later learns it was all a trick of the Mist, she believed she was once his girlfriend while they attended the same school. She works hard to recreate this relationship in real life when she comes to Camp Half-Blood. She is also friends with all of the seven quest members in The Heroes of Olympus, especially Annabeth, Leo and Percy.
Piper's main weapon is her dagger Katoptris, though she later acquires a magic cornucopia and uses it as a weapon. After being captured by pirates in The House of Hades, Piper asks Hazel to teach her sword fighting, using a jagged celestial bronze sword taken from the Boread Zethes.
In The Hidden Oracle, Nico mentions that Piper is currently attending school in Los Angeles, together with Jason. In The Burning Maze, it is revealed that her relationship with Jason ended a few months earlier. Apollo, as Lester Papadopoulos, is confused because the cloud nymph, Mellie, had seemed angry at Jason, leading Apollo to mistakenly believe that Jason had broken up with Piper, while in fact, Piper had ended the relationship because she felt it was forced. It is later unveiled that she wanted to discover herself and who she really was without the pressure of being the daughter of Aphrodite. The trick of the Mist that Hera used at the beginning of their relationship also contributed to the breakup as that meant that their relationship was technically "fake". Still, she is heartbroken when he sacrifices himself in The Burning Maze. In The Tower of Nero, because he was still one of her best friends who she could confide in. Later, she is revealed to be in a relationship with a mortal woman named Shel.
In The Sun and the Star, after returning from Tartarus, Nico contacts Piper who is still with Shel. The two discuss their grief over the loss of Jason and promise to be closer friends in the future. Piper reveals that she is truly happy with Shel, although she is still figuring herself out which Nico gives her advice on. Piper also admits that she had truly loved Jason.
Jason Grace
Jason Grace was a son of Jupiter and the mortal Beryl Grace, and the younger brother of Thalia Grace (Hunter of Artemis). He was raised by the wolf goddess Lupa and her pack after his mother was compelled to give him up when he was two, then later lived at Camp Jupiter, the Roman equivalent of Camp Half-Blood. Jason inherited many special powers from his father Jupiter like summoning lightning bolts, controlling winds, flying, summoning storm spirits, and creating different types of storms like thunderstorms, rainstorms, and hurricanes. Jason is also a master swordsman and spear user. He and Thalia are reunited in The Lost Hero, and Thalia later reveals that their mother told her that Jason was dead, and that this was what finally drove her to leave home. Also in The Lost Hero, he begins a romantic relationship with Piper McLean. In The Blood of Olympus, it is revealed that Beryl Grace had become a mania, or spirit of madness.
Jason is often described to be very handsome and attractive. He had blond hair, electric blue eyes, and a scar above his upper lip, which is said to be from his attempt to eat a stapler at age two. By the age of fifteen, he had earned the rank of praetor and led the legion with his longtime partner, Reyna who eventually falls in love with him. Jason also coordinated the Roman camp's attack on the Titan force prior to the events of The Lost Hero: he led an assault against Mount Tamalpais/Othrys, a Titan stronghold near San Francisco, and defeated the Titan Krios in combat by himself. Piper McLean describes Jason as a very rule- and duty-oriented person, though Terminus describes him as a "rule-flouter”. Of all the characters in the series, Jason is the one who struggles the most with the differences between the Greek and Roman perspectives. When the Argo II is stuck in North Africa, he must choose one identity or the other; he decides to consider himself a Greek, despite his parentage, and is subsequently unable to command a legion of Roman ghosts. During The House of Hades, it is revealed that Jason has plans to return to Camp Jupiter to improve it with things he learned at Camp Half-Blood, such as giving the fauns (the Roman equivalent of a satyr) more rights and responsibilities. Later, during The Blood of Olympus, Jason decides to consider both the Greek and Roman traditions as part of his heritage. He becomes the Pontifex Maximus, a role which sees him travel between Camp Half-Blood and Camp Jupiter to build shrines for every god and goddess in the pantheon.
Jason is killed with arrows during The Burning Maze by the Roman Emperor Caligula after sacrificing himself to save Piper, Apollo, and Meg. His death is avenged by Frank Zhang in The Tyrant's Tomb with Frank telling Caligula that it's for Jason. Jason is given a state funeral in New Rome overseen by Apollo. In The Tower of Nero, Nico senses that Jason has likely moved on to either Elysium or been reborn.
Hazel Levesque
Hazel Levesque is a fourteen-year-old demigod, a daughter of Pluto and Marie Levesque. She first appears in The Son of Neptune, at Camp Jupiter. It is later revealed that she has returned from the dead, assisted by her half-brother Nico. She grew up in the 1940s in New Orleans, where her mother had a gris-gris shop. When she was born, Pluto offered to grant her mother a wish, but her request for wealth backfired into an ability to control precious metals and gems, which both first view as a curse. Hazel died after Gaea tries to use Hazel's power over earth to resurrect Alcyoneus. When Hazel's mother changes her mind about helping Gaea, Hazel buries herself and her mother under the earth, delaying Alcyoneus's rebirth and killing them both. While Hazel's spirit is being judged, she gives up the chance to go to Elysium to save her mother from punishment, and they are both sent to the Fields of Asphodel instead. At some point before The Lost Hero, Nico finds Hazel in the Underworld while trying to visit Bianca, only to find she has tried for rebirth. With the Doors of Death open, Nico is able to take Hazel to the world of the living through them, resurrecting her and then delivers Hazel to Camp Jupiter. Hazel and Nico are protective of each other, much as true half-siblings.
Hazel is described as African American, having cocoa-colored skin, curly cinnamon-brown hair, and golden eyes. Her legion tattoo is described as looking like a cross with curved arms and a head. She eventually learns to manipulate her curse, manipulating precious stones and metals and sensing structures underground. She is an accomplished horse-rider and skilled with a spatha. She tames the horse Arion, who eats precious metals. She is unusually knowledgeable about the Underworld because of her time there. During The House of Hades the goddess Hecate insists Hazel learn to manipulate the Mist. Hazel becomes very gifted at this. After the Second Gigantomachy, Hazel is promoted to the rank of centurion of the Fifth Cohort, succeeding her boyfriend Frank Zhang. During The Tyrant's Tomb, Hazel reveals that she has managed to break her curse with Frank, which is confirmed in The Tower of Nero. This confirms something that Juno had once told Hazel: that a descendant of Poseidon would some day wash away her curse. She is now able to summon precious metals and use and spend them without terrible consequences. In The Tyrant's Tomb, she and Frank team up with Apollo and Meg McCaffrey to protect Camp Jupiter from the emperors Commodus and Caligula as well as the undead king Tarquin. In The Tower of Nero, she and Frank are stated to be the best praetors that Camp Jupiter has ever had.
Frank Zhang
Frank Zhang, born Fai Zhang (Frank's Chinese name), is a 16-year-old demigod, son of Mars (Ares) and Emily Zhang, a Chinese-Canadian "legacy" (descendant of a demigod) who died during military service in Afghanistan. He is taken care of by his grandmother after his mother's death, and makes his way to Camp Jupiter upon her insistence. Frank's family descends from Periclymenus, a grandson of Poseidon, who had the power to shapeshift. Periclymenus's descendants were sold into slavery in China, and migrated to Canada many years later. While battling Alcyoneus (who is invincible within Alaska), Frank taps into his ancestral power and transforms into a bear. However, his combined power of being a son of Mars and having the ability to shapeshift makes his life very fragile. The Fates tied his life force to a piece of firewood when he was a baby, so if the wood burns up, he will die (as in the ancient Greek legend of Meleager). The goddess Juno appears to his mother and grandmother while he is a baby to warn them of this fact, as he would be crucial to defeating the Giants. In all of his life, Frank has ignited the wood twice, which he can do simply by thinking about it; the first time is while he is finding his way to Camp Jupiter, in bitter cold. The second time is when he, Percy, and Hazel travel to Alaska to free Thanatos. Eventually, Frank entrusts the firewood to Hazel, and in The House of Hades, Leo creates a fireproof pouch to contain it.
Frank has a meek disposition and is uncomfortable upon learning his father's identity publicly in front of the whole of Camp Jupiter. He suspected himself a son of Apollo, given his skill with a bow and arrow. On his quest in The Son of Neptune, and later during the series as well, he uses an enchanted spear given to him by Mars. The spear summons a skeleton warrior, which Frank calls "Gray".
As he has been residing in Camp Jupiter for no more than a year, Frank is initially considered a probatio, or rookie, of the Fifth Cohort. During the Roman War Games, after Percy impresses everyone with his battle skills and instincts, Mars appears, informing Frank that he is his son and is to lead a quest. Since only centurions are allowed to lead a quest, Reyna has to promote him to centurion rank. Later, in The House of Hades, Jason surrenders his praetorship to Frank, who uses its authority and Diocletian's Sceptre to lead an army of Roman skeleton soldiers against the monsters in the Necromanteion.
Frank was described as 'cuddly' and 'fuzzy' and with a chubby, babyish face in The Mark of Athena, but in The House of Hades, after summoning the blessing of Mars to defeat a hoard of enemies, he transforms. He is then described as being taller, more muscular, and without all of his childhood fat. Though now built like a professional football player, he is still as sensitive as before, and is embarrassed at his new appearance at first.
Initially, Frank is wary of the tension between Hazel and Leo (caused by Leo's resemblance to Hazel's old boyfriend, Sammy Valdez). After Leo's encounter with Calypso, however, Leo becomes more relaxed around Hazel and their relationship becomes clearly platonic, much to Frank's relief. Frank then pursues a relationship with Hazel.
Frank burns his stick for the final time in The Tyrant's Tomb to kill Caligula. Despite the stick completely burning, Frank survives, freeing him from his curse. Apollo believes that by taking his fate into his own hands in such a noble way, Frank has created a new fate for himself free of his curse. Apollo compares Frank's fate to Meleager, noting that Meleager's family had hidden his curse from him and his mother was eventually forced to use the firewood to kill him while Frank's family revealed the truth and it helped to shape who Frank became. It's also revealed that his romantic relationship with Hazel has enabled her to break her curse, fulfilling a prophecy that she had received that a descendant of Poseidon would wash away her curse.
In The Tower of Nero, Frank and Hazel are revealed to have become the most efficient praetors the Twelfth Legion has ever had and have been building up New Rome.
Coach Gleeson Hedge
Gleeson Hedge is a satyr first mentioned in The Last Olympian, as the author of a distress call sent to Grover Underwood. Like Grover, Hedge is also a demigod Protector, his proudest "recruit" being Clarisse La Rue. He disguises himself as a coach at the Wilderness School to escort Piper McLean and Leo Valdez (and later, Jason Grace) to Camp Half-Blood. He also serves as the adult chaperone for the Argo II and later accompanies the Athena Parthenos to camp. Despite his often warlike and often overly aggressive attitude, Hedge is kind and understanding to campers in need. He enjoys extreme sports and martial arts movies. In The Lost Hero, Hedge falls in love with cloud nymph Mellie (assistant to Aeolus) and marries her; by the time of The House of Hades, Mellie is pregnant with a satyr boy. Chuck, the baby, is born at the end of The Blood of Olympus, with Clarisse as his godmother. In The Hidden Oracle, Hedge, Mellie, Chuck, Piper, and Jason are spending the winter in Los Angeles.
Apollo, in the mortal form of Lester Papadopoulos, serves as the main protagonist of The Trials of Apollo series.
In The Heroes of Olympus, Apollo's Roman descendant Octavian promises the god many things for blessing his prophetic skills, which leads to the Olympians' distraction from the true threat of Gaia, and to the resurgence of Python. As a result, the Delphic Oracle ceases to function, effectively halting demigod quests, and Zeus punishes Apollo. Zeus's punishment consists of making Apollo mortal, though he retains most of his personality and some more minor powers. This punishment is revealed in The Trials of Apollo. In his mortal form, Apollo's name is Lester Papadopoulos. Apollo has to adjust to a life of mortality and questing to regain his former powers and lifestyle.
Following a meeting with two thugs in Manhattan, Apollo encounters a demigod called Meg McCaffrey, who claims him as her servant until he regains his godhood. Apollo is released by Meg after the revelation of her alliance with his enemy. His quest to become a god again is to liberate the oracles and face down his demons and the brutal mistakes he's made. Apollo is a truly flawed yet humorous character with a deeper capacity for growth and love than even his blameful, punishing father Zeus realizes.
As Lester, Apollo is a 16-year-old teenager with curly brown hair, blue eyes, acne, and a "flabby" torso. He is narcissistic, prideful, and arrogant. His mortal transformation makes him empathize with mortals and reaches a higher understanding of the worth of life, the meaning of death, and what it means to be alive. In particular, he grows to care for Meg deeply and resolves to be there for her despite the difficulties involved.[11] After killing Python in The Tower of Nero, Apollo is reinstated as a god but is changed for the better by his time as a mortal, having grown up and established real relationships with his children and others. He doesn't define himself sexually but has been in relationships with both females and males.
Meg McCaffrey
Margaret (Meg) McCaffrey is a 12-year-demigod daughter of Demeter and the main character in The Hidden Oracle. Her father was murdered by "the Beast" (Emperor Nero) and she was subsequently adopted by Nero, gaslighted into personifying Nero's evil actions as separate from him. Nero taught her the arts of a demigod and gave her a pair of crescent rings which can transform into sickles made of imperial gold, before giving her a task to lure Apollo into the Grove of Dodona. Meg appears to Apollo in an alley of Hell's Kitchen, Manhattan where she defeats two thugs, who were sent by Nero to stage a robbery. Meg demands Apollo's servitude and they travel to Camp Half-Blood with Percy Jackson's assistance. There, Meg displays unusual abilities even before Demeter claims her, and later goes with Apollo to search for missing demigods and the Grove in the nearby woods, having to endure a brief abduction in the process. Her relationship with Nero is revealed at the climax, but her growing doubtfulness regarding Nero's ways, not to mention her already familiar friendship with Apollo, leads her to rob Nero of his chance of burning the Grove. While she helps Apollo bring the Grove alive, she severs their bonding spell and leaves.
In the second book, The Dark Prophecy, she returns to Apollo and helps him fight Commodus.
Meg is described as small and pudgy, with dark hair chopped in a messy pageboy style and black cat-eye glasses with rhinestones in the corners. She is free-spirited and adventurous, inquisitive, and is also confrontational. She poses questions with no subtlety, something that Apollo is annoyed with but later comes to regard as a unique trait. Her abilities as Demeter's daughter allows her to connect better with nature as well as summoning a karpos (crop spirit) called Peaches, a power that none of Demeter's other demigod children are known to possess.[11]
Even though she is Demeter's daughter, not Ceres (the Roman manifestation of Demeter) she fights like a Roman, with two swords; one for offense and one for defense. She is also known for her liking of unicorns in the fourth book The Tyrant's Tomb.
Hemithea
Hemithea, known as "Emmie", is a retired Hunter of Artemis and caretaker of the Waystation. She lives with her partner, Josephine, also an ex-Hunter, and their daughter Georgia at the Waystation in Indianapolis. She and her sister were granted immortality by Apollo after escaping from the wrath of their father, King Staphylus. She then joined the Hunters of Artemis and fell in love with fellow hunter Josephine, so sometime in the 1980s, Josephine and Emmie gave up their immortality to grow old together. In The Dark Prophecy, she saves Calypso, Leo and Apollo from the Blemmyae with crossbow turrets and lets them stay at the Waystation. She comments on the similarities between Calypso and her half-sister Zoë Nightshade.
Triumvirate Holdings
Triumvirate Holdings is a company that is led by three beings who are said to be the worst Roman Emperors in history. They force other people to worship them. During the Second Titanomachy, Triumvirate Holdings was responsible for giving Luke (at the time under the influence of Kronos) and his allies the Princess Andromeda, weapons, helicopters, and top human mercenaries. During the Second Gigantomachy, Triumvirate Holdings supplied Octavian with different weapons. Rachel described Triumvirate Holdings to be so rich that they make her father's company "look like a kid's lemonade stand". The trio have divided up North America into three major empires and are hunting for Oracles, which they plan to destroy.
Among the known members of Triumvirate Holdings are:
Emperor Nero – A legacy of Apollo who is the main antagonist of The Hidden Oracle and one of the two main antagonists of The Tower of Nero alongside Python. The last in the Julio-Claudian dynasty, Nero is infamous for his tyranny and overindulgence in wealth and luxury with little regard to his subjects. He is the deified Roman Emperor, who has survived through the millennia along with two other deified Roman emperors—the Triumvirate. He forms an alliance with Python, who holds Delphi, while he himself controls the other oracles and plans to destroy Dodona. As the Emperor of the East, Nero lives in New York City, where he recruits and trains homeless demigods, and controls the eastern third of North America. He and the other two Roman Emperors have established Triumvirate Holdings. As "the Beast", Nero killed Meg's father, but later adopted and trained her in demigod arts so she could eventually lure Apollo into the Grove of Dodona. After Rhea restores the Grove of Dodona at Camp Half-Blood, Nero tries to force Apollo and Meg to burn the trees; failing at that, he sends a giant statue of himself, the Colossus Neronis, which originally stood in Rome, against Camp Half-Blood and Apollo and the Greek demigods defend the camp against it.[11] He is killed by Apollo in The Tower of Nero and his power absorbed by Python.
Emperor Commodus - Commodus is the main antagonist of The Dark Prophecy and one of the three main antagonists in The Tyrant's Tomb alongside Caligula and Tarquin. The last in the Nerva-Antonine dynasty, Commodus ascended as emperor at a young age and was known for his good looks and musculature, for which he was nicknamed the "New Hercules". In later life, he became increasingly dictatorial and paranoid as he suspected that people would overthrow him. He also had preferences for gladiatorial battles and would buy slaves and exotic animals to fight to the death. Eventually, Apollo, with whom he had an affair, assassinated him while taking the form of Narcissus, his wrestling partner. As a god, he reigned as the Emperor of the Middle, ruling from a base at Indianapolis. He sends many of his men, including a kidnapped Georgina, to seek the Oracle of Trophonius, as he himself fears the oracle's reputed ability to drive its seekers insane. At the end of The Dark Prophecy, he launches an attack at the Waystation, but is defeated by Apollo and his group. He manages to get away at the last second, having been blinded by Apollo's brief revelation of his true form. Later, Commodus joins forces with Caligula and Tarquin to destroy Camp Jupiter but ends up being killed by Apollo again.
Emperor Caligula - The main antagonist of The Burning Maze and one of the three main antagonists in The Tyrant's Tomb alongside Commodus and Tarquin. He was born into the first ruling family of the Roman Empire, conventionally known as the Julio-Claudian dynasty. Caligula was ambushed by his Germani guards which led to his mortal death. Following this incident, he employed the Strix and the Pandai to work for him while his fellow emperors continue to use Germani. Many years later, Apollo and Piper were brought to Caligula by his talking horse Incitatus as Caligula has the Pandai they subdued executed. Before he can have Meg and Jason Grace executed, Caligula is stunned when Apollo threatens to commit suicide. After Apollo stabs himself while Caligula kills Crest following the news of the attack on Camp Jupiter ending in failure, Caligula sails north with his guards. Medea meets with Caligula and advises that performs a ritual before Apollo dies. Caligula later fights Jason and Tempest on the back of Incitatus where he manages to kill Jason. After making sure that he is dead, Caligula sets sail for the Bay Area. Later, Caligula joins forces with Commodus and Tarquin to destroy Camp Jupiter but ends up being killed by Frank who apparently sacrifices himself to destroy the emperor by burning up his firewood representing Frank's lifeline. To much surprise, Frank survives the experience and is left with his life no longer tied to the wood.
King Tarquin - One of the three main antagonists in The Tyrant's Tomb alongside Commodus and Caligula. Tarquin is the last king of Rome and is depicted as a zombie. He participated in the Battle of San Francisco Bay where he targeted the Sibylline Books. Tarquin was killed by Hazel and Diana who stabbed him in the chest and shot him in the head with an arrow respectively.
Greek-Roman deities
The Olympians
Though not all the gods who appear in Rick Riordan's novels are truly Olympians (that is, gods who live on Mount Olympus), all Greek and Roman gods are generally considered to be a subset of the Olympians. As such, most characters in the series refer to these immortals generally as the "Olympian gods", to distinguish them from the Greco-Roman primordial gods and Titans.
Zeus/Jupiter – The king of the gods and the most powerful Olympian by far, Zeus is most prominent in The Lightning Thief[2] but has several roles throughout the rest of Percy Jackson & the Olympians. Zeus is shown prominently throughout the series to be extremely narcissistic, paranoid and hypocritical. In The Lost Hero, under the influence of Khione, Zeus forbids contact between gods and mortals and closes off Olympus (against the influence of Khione), although he indirectly helps the protagonists several times on their quests.[8] As the primary Olympian god, his demigod children reside in Camp Half-Blood's biggest cabin, Cabin 1, although there is only one person who resides there at the end of The Heroes of Olympus: Jason. In the film adaptation, Zeus is portrayed by Sean Bean. In the TV series, he is portrayed by Lance Reddick in season one as one of his final roles before his untimely death. When Percy gives Zeus the Master Bolt to him while stating that Kronos had orchestrated it's theft, Zeus still plans to continue the war with Poseidon. As Percy states that Ares turned on him when "someone stronger showed up" and asks what the other Olympians will think of him when Kronos returns to put him back in his place, Zeus tries to strike Percy with the Master Bolt only for Poseidon to intervene and surrender. As Zeus plans to have Athena set a meeting with the other Olympians about Kronos' threat after a brief discussion with Poseidon, he leaves telling Poseidon to make sure he never sees Percy again.
Hera/Juno – The queen of the gods who plays a role in The Titan's Curse,[12] by helping Percy and the others on their quest in The Battle of the Labyrinth.[6] As Juno in The Lost Hero, she is kidnapped by Gaea, and contacts Jason Grace to rescue her. Previously as Juno, she had sneaked out of Olympus and switched Percy and Jason to try to unite the Roman and Greek demigods, going against the wishes of Zeus as part of a plan to defeat Gaea.[8] Her cabin in Camp Half-Blood is Cabin 2, the second biggest in the camp. Because she does not have demigod children, it is empty. In the film adaptation, Hera is portrayed by Erica Cerra.
Poseidon/Neptune – The god of the sea, earthquakes, and horses who is the brother of Zeus and Hades. In The Lightning Thief, he is suspected of having stolen Zeus's master bolt with Percy's help which nearly started a war between Zeus and Poseidon. Percy is proven innocent after Percy recovers it from Ares.[2] Poseidon fights Oceanus in the underwater front of the Titan war. He remains there in The Last Olympian while the other Olympians fight Typhon, until Percy convinces him that his power is necessary to defeat Typhon. He was last seen fighting the Giants in the Second Gigantomachy alongside Percy and the other gods and demigods and mentioned Kymopoleia to the other gods as his daughter after Percy and Jason reported meeting her.[10] Though he is referred to as Neptune in the sequels of Percy Jackson and the Olympians when the Greeks and Romans are united, he has yet to appear in Roman form. His cabin in Camp Half-Blood is Cabin 3 in which Percy is the sole permanent occupant.In the film adaptation of The Lightning Thief, Poseidon is portrayed by Kevin McKidd. In the musical, he is portrayed by Jonathan Raviv. In the TV series, he is portrayed by Toby Stephens. He is first seen in a flashback talking to Sally where he advised her not to take him to Camp Half-Blood yet. Poseidon shows up in person to prevent Zeus from striking Percy by "surrendering".
Hades/Pluto – The god of the Underworld and brother of Zeus and Poseidon. He is an isolationist who distances himself constantly from other gods because they do the same to him, primarily out of fear.[13] They continuously underestimate Hades who is in fact a very honorable and fatherly individual. He is the father of Nico, Bianca, and Hazel Levesque (as Pluto). Hades was the one who teleported Sally Jackson to the Underworld during the Minotaur's attack on her and Percy. Percy, Annabeth, and Grover assumed that he was the culprit behind the Master Lightning Bolt's theft only to find out that he wasn't and that his Helm of Darkness was also stolen. After Percy defeated Ares, he gave the Helm of Darkness to the Furies for them to return to Hades. He returned Sally to the living afterwards. After the Second Titanomachy, Hades is granted Cabin 13 which is populated by his demigod child Nico and is given a throne on Mount Olympus. In the film adaptation of The Lightning Thief, Hades is portrayed by Steve Coogan and is depicted as having a fiery winged demon form. In the TV series, Hades is portrayed by Jay Duplass.
Demeter/Ceres – The goddess of agriculture. She appears alongside her daughter Persephone in The Last Olympian, where they participate in the battle against the Titans.[7] Demeter's cabin in Camp Half-Blood is Cabin 4. In the film adaptation of The Lightning Thief, Demeter is portrayed by Stefanie von Pfetten.
Ares/Mars – The god of war who is the son of Zeus and Hera and the father of Deimos, Phobos, Eros, Clarisse La Rue, and Frank Zhang. Ares is a callous bully who is driven by either greed, aggression, violence or by the promise of violence. However, as Mars, he dislikes war without reason and is one of the more important Roman Gods. He is however still a bully and is all for killing the Greeks. Percy first encounters Ares in The Lightning Thief, in which he drives a black Harley-Davidson motorcycle with flame decals and a leather seat made from human skin. Percy defeats Ares in a sword fight near the climax of the book. Before fleeing in his divine form, Ares curses Riptide to fail Percy when he needs it the most. Cabin 5 in Camp Half-Blood is the home of Ares' demigod children; it is said to be surrounded by all kinds of warfare apparatus, including spikes.[2] In the film adaptation of The Lightning Thief, Ares is portrayed by Ray Winstone. In the musical, he is portrayed by James Hayden Rodriguez. In the TV series, he is portrayed by Adam Copeland. Unlike the book series, Ares doesn't curse Riptide and states that Percy has made an enemy for life.
Athena/Minerva – The goddess of wisdom, and the daughter of Zeus and Metis. Athena first appears in The Titan's Curse, where she dislikes Percy and his relationship with her daughter, and votes to execute Percy due to his crucial role in the fate of Olympus. She then argues that it was the most logical and wise choice. As Minerva, she is a scatterbrain and lost. She hates the Romans for reducing her to that and tells her descendants to kill the Romans. She also leads her best children to the Athena Parthenos, although Aphrodite believes it to be subconscious, as Athena doesn't know where it is. After an argument between Minerva and Annabeth, she revokes the magical properties of her daughter's Yankees cap, but Athena eventually restores them to help against Serapis. In The Chalice of the Gods, Athena helps Percy on his quest to return Ganymede's stolen chalice which Annabeth takes as a sign that her mother has finally accepted their relationship. Her color scheme is grey,[12] and her cabin in Camp Half-Blood is Cabin 6. In the film adaptation, Athena is portrayed by Melina Kanakaredes.
Apollo – The god of the sun, light, music, truth, and healing. His Greek children live in Cabin 7 in Camp Half-Blood. He serves as a supporting character in Percy Jackson & the Olympians and The Heroes of Olympus series, and becomes the main protagonist of The Trials of Apollo series as a mortal named Lester Papadopoulos. Apollo first appears in The Titan's Curse, where he transports a group of demigods and Hunters at the behest of his twin sister Artemis. Later, he assists the quest group in rescuing Artemis from the Titans, even though doing so has been forbidden by Zeus. At the end of The Last Olympian, Apollo chooses Rachel Dare as his new Pythia. After the war in the second series, the furious Zeus punishes Apollo with mortality for his failure to identify Gaea as a threat. In the film adaptation of The Lightning Thief, he is portrayed by Dimitri Lekkos.
Artemis/Diana – The goddess of the moon, animals, youth, and hunting. Artemis is the daughter of Zeus and Leto and the twin sister of Apollo. Artemis, true to her vows, is distrusting of men who discourages the companionship or value of men, and encourages maidenhood. As a result, she has no demigod children, but recruits Hunters who serve as her companions and attendants. Cabin 8 is her honorary home at Camp Half-Blood, but because she is a virgin, it is populated only when her Hunters come to visit. Her Roman counterpart Diana only appears in The Tyrant's Tomb when Apollo summons her to help New Rome. Diana kills Tarquin and heals her brother's zombie infection. In the film adaptation of The Lightning Thief, Artemis is portrayed by Ona Grauer.
Hephaestus/Vulcan – The gods' blacksmith, and the father of Charles Beckendorf and Leo Valdez. At Camp Half-Blood, Cabin 9 is dedicated to him. Hephaestus acts as a major ally of Percy in The Battle of the Labyrinth. In The Lost Hero, he defies Zeus by speaking to Leo through his dreams and delivers the head of the mechanical dragon Festus for use as the figurehead for the Argo II. In the film adaptation of The Lightning Thief, Hephaestus is portrayed by Conrad Coates. Timothy Omundson portrays Hephaestus in the TV series. Unlike the book series, Hephaestus shows up early where he finds Annabeth in his amusement park hideout with Percy trapped in the same throne that Hera was once trapped in. After agreeing to free Percy, he allows them to claim Ares' shield as Hephaestus tells Annabeth that he'll put in a good word to Athena.
Aphrodite/Venus – The goddess of love and beauty, who first appears briefly in The Titan's Curse. Her appearance shifts constantly, always becoming more beautiful.[12] Cabin 10 at Camp Half-Blood is the home of her demigod children. In The Lightning Thief, Aphrodite is portrayed by Serinda Swan.
Hermes/Mercury – The messenger of the gods, and the god of travelers and thieves. He is the son of Zeus and Maia. In the Percy Jackson and the Olympians series, Hermes helps Percy, hoping that he will be able to redeem Luke.[1] All unclaimed demigods are packed into Hermes' cabin, Cabin 11 because Hermes welcomes all travelers. In the film adaptations, Hermes is portrayed by Dylan Neal in the first film and by Nathan Fillion in the second. In the TV series, he is portrayed by Lin-Manuel Miranda. Unlike the book series, Hermes is found at the Lotus Hotel and Casino where Percy and Annabeth try to get him to help them get into the Greek underworld. He was reluctant to help them due to an event that strained his relationship with Luke and that Poseidon advised him not to help anymore people get into the Greek underworld. After having found that Annabeth pickpocketed him, he does leave instructions and a map for them on his car.
Dionysus/Bacchus also known as Mr. D – The god of wine, parties and madness who is the son of Zeus and Semele. Dionysus was made the head of Camp Half-Blood as punishment for pursuing "an off-limits wood nymph" romantically. He is also banned from drinking alcohol as a part of his punishment and so is often seen drinking Diet Coke as a substitute. Dionysus is portrayed as a cynical and unfriendly misanthrope who does not appear to have much respect for other beings except for Ariadne. He is a powerful god, but his powers are shown the least throughout the series. He has two demigod sons named Castor and Pollux, both of whom are the sole inhabitants of Cabin 12. As Bacchus, the Roman centurion Dakota is his son. Dionysus was once a demigod who, like Hercules, was made into a god. His seat on the Olympian Council originally belonged to Hestia who decided to abdicate it after Dionysus was first made into a god to avoid conflict. Dionysus hates his job and has a low opinion of demigods, likening them to Theseus and his abandonment of Ariadne. However, he is shown to be kind and helpful towards demigods on a few occasions, saving Percy and his friends from the Manticore in The Titan's Curse, curing Chris Rodriguez's madness in The Battle of the Labyrinth and giving Nico counseling sessions in The Trials of Apollo following the death of Jason Grace. He typically refers to Percy by variations on his real name, only ever calling him Percy Jackson a few times in the series, usually only in extremely serious moments. In The Last Olympian, his sentence is shortened to only fifty more years following the defeat of Kronos. In The Mark of Athena, Dionysus' Roman form Bacchus appears to help the Heroes against two of the giants once they prove themselves to him. In The House of Hades, the giant Clytius states that it took the combined forces of Dionysus and Hercules when they were both demigods to defeat him the last time. In The Tower of Nero following his own punishment, Apollo suggests to Dionysus that Zeus might have a greater purpose to forcing Dionysus to run Camp Half-Blood and not to lose hope. Dionysus is portrayed by Luke Camilleri in the first film and by Stanley Tucci in the second. In the musical, he is portrayed by George Salazar. In the TV series, he is portrayed by Jason Mantzoukas.
Hestia/Vesta – The goddess of the hearth and home. Like Artemis, she swore a vow of chastity so no conflict can spring up about her allegiance. As a result, she does not have any demigod child. Hestia gives up her golden throne on Olympus to Dionysus/Bacchus to keep the peace on the Olympian council, making the number of male and female gods unbalanced with seven men and five women. She is the title character of The Last Olympian, where she helps Percy figure out how to defeat Kronos. During the final battle, Hestia intervenes briefly to destroy her father's scythe after Percy knocks it into Hestia's hearth, Hestia briefly appearing amidst the flames to give Kronos a disapproving look. She is described as preferring the shape of a young and softspoken girl with brown hair. She is also one of the only gods who has not tampered with the lives of Percy and his friends. In The Lightning Thief, Percy spots her on his first day of camp, but mistakes her for a regular young girl.
Minor Greco-Roman gods
Achelous – A river god with the face of a man and the head of a bull. He had previously fought with Hercules where Hercules removed one of Achelous' horns; his other horn plays a part in the plot of The Mark of Athena in which it is removed by Piper McLean and becomes a cornucopia.
Aeolus – God of the wind. In The Last Olympian, he manipulates the winds to form a barrier around Olympus protect it from the Titans.[7] In The Lost Hero, he is portrayed as frenetic and unbalanced by attempting to fill all the requests of the gods and hopes to be made god of the wind.
Amphitrite/Salacia – The Queen of the Sea and wife of Poseidon/Neptune. She appears in one scene of The Last Olympian and is described as a beautiful goddess wearing armor with black hair and small horns resembling crab claws.
Boreas/Aquilon – The god of the north wind and winter. He is first seen in The Lost Hero where Jason, Piper, and Leo ask for assistance. He has two immortal children called the Boreads and is the father of Khione.
Khione – The goddess of snow who is the daughter of Boreas and sister of the Boreads. She first appears in The Lost Hero when she betrays Jason, Piper, and Leo to the forces of Gaea. In The House of Hades, she attacks the Argo II and banishes Leo to Ogygia before she is defeated by the combined forces of Piper and Festus.
The Boreads – The sons of Boreas and the brothers of Khione. Calais is depicted as a big simpleton who struggles with words that have more than two syllables, while Zethes is shown to be heterosexual and to maintain an eighties hairstyle. In The Lost Hero, the Boreads are seen with Boreas. In The House of Hades, Khione and the Boreads attack the Argo II. The three of them are defeated when Piper McLean charmspeaks Festus to life. Piper also takes one of the Boreads' celestial bronze swords for her own use.
Notus/Auster – The god of the south wind and summer. He appears in The House of Hades where the damaged Argo II is docked at his palace for several days. The god is depicted as switching often between his Greek and Roman forms, causing a great deal of frustration for Jason Grace in their negotiations. He eventually encourages Jason to simply take what he wants and to choose between being Greek or Roman, at which point the god settles on the form of Notus due to Jason's choice of Greek. Notus then lends the demigods four venti to tow their damaged ship to Malta.
Zephyrus/Favonius – The god of the west wind and spring. He appears in The House of Hades. In The Hidden Oracle, Apollo suspects that Zephyrus gives him aid against the Colossus Neronis after accepting Apollo's apology to him.
Eurus/Vulturnus - The god of the east wind and autumn.
Asclepius/Vejovis – The god of healing who is the son of Apollo and Phoebus. In The Blood of Olympus, Asclepius is first mentioned by Apollo on Delos, as the only person to have ever successfully cured death. Apollo gives Leo, Frank, and Hazel his location in Epidaurus. Piper, Leo, and Jason later meet Asclepius in the Asclepion. He quickly diagnoses Jason with myopia and gives him a pair of glasses. Later, he uses the Pylosian mint and the Makhai to formulate the physician's cure and gives the trio instructions on its use which allows Festus to resurrect Leo after his death.
Enyo/Bellona – The goddess of war, who is the mother of Hylla and Reyna (as Bellona). Though she is never seen in the series, she indirectly helps Reyna to kill Orion by empowering her with her strength.
Britomartis - The goddess of hunting and fishing nets. In The Dark Prophecy, she encounters Apollo, Leo Valdez, and Calypso at the Waystation where she tasks them to retrieve her pet gryphons, Heloise and Abelard, as payment for the secret route to the lair of Commodus. Later, she contacts the Hunters of Artemis to serve as backup for the protection of Waystation. Britomartis also jump-starts Calypso's lost magic.
Deimos – The god of terror. A son of Ares, Deimos appears in the short story "Percy Jackson and the Stolen Chariot" in The Demigod Files, where he torments Clarisse, forcing Percy and Clarisse to cooperate to defeat him.[14] In The Blood of Olympus, he helps to defeat the giant Mimas.

In The Blood of Olympus, Gaea times her awakening to coincide with the Feast of Spes, a Roman festival honoring the goddess.
Eris/Discordia – The goddess of chaos and the daughter of Nyx. In The House of Hades, Percy and Annabeth encounter Eris alongside Nyx and Eris' siblings near the Mansion of Night.
Eros/Cupid – The god of love who is the son of Aphrodite/Venus and Ares/Mars. In The House of Hades, Jason and Nico convince Cupid to give them Diocletian's Scepter.
Ganymede – The cupbearer of the gods, who appears in The Sea of Monsters as part of a public service announcement advising users of the Gray Sisters' taxi service to use the seat belt. In The Chalice of the Gods, Ganymede's chalice is stolen by Geras the god of old age and he enlists Percy Jackson's help to get it back. He is depicted as a beautiful teen, but one who is stuck with all of his anxiety, self-doubts and fears forever while retaining Zeus' attention and the other gods' scorn. In Percy Jackson: Sea of Monsters, Ganymede is portrayed by Richard Yearwood.
Geras – The god of old age and the son of Nyx. In The House of Hades, Geras is among the children of Nyx that encounter Percy and Annabeth near the Mansion of Night. In The Chalice of the Gods, he steals Ganymede's chalice. Percy wins the chalice back by embracing Geras and in so doing, old age, mortality and everything that comes with it which earns him Geras' respect.
Harpocrates - The god of silence, who was imprisoned by Triumvirate Holdings and used to silence all demigod communications. After being freed by Apollo, Reyna and Meg, he wills himself out of existence to help defeat his captors and save Camp Jupiter, bringing an end to the communications blackout. However, it takes months to fade fully with demigod communications only being fully restored by The Sun and the Star three months later. It's revealed that he was once an incarnation of the Egyptian god Horus, but Greek belief in him as a separate entity had turned Harpocrates into a minor Greek-Egyptian hybrid deity.
Hebe/Juventas – The goddess of youth who is the daughter of Zeus and Hera and wife of Heracles. Hebe is amongst the minor gods who allied themselves with the Titans. After the war, she is awarded Cabin 18 in Camp Half-Blood. In The Chalice of the Gods, she's one of the suspects for the theft of Ganymede's chalice, but she's ultimately cleared of any wrongdoing.
Hecate – The goddess of magic, who is an ally of Kronos in the Percy Jackson and the Olympians series, but does support the gods against Gaea. Her empousai minions and her daughter Circe is a feminist that morphs men into pigs and torments Percy in The Battle of the Labyrinth and The Sea of Monsters, respectively.[1][7] After the Titans are defeated, she reconciles with Olympus and is granted Cabin 20 at Camp Half-Blood for her children. In The House of Hades, Hecate reveals that she was the one who had led Hazel Levesque's mother to the spell that had summoned Pluto. Hecate teaches Hazel how to use magic and helps to guide the Argo II to Epirus. At the Doors of Death, Hecate teams up with Jason, Leo, Frank, Piper and Hazel to defeat the giant Clytius, the bane of magic.
Hudson River – A river god who personifies the river in New York. He only appears in The Last Olympian where he sinks Titan ships coming to attack Olympus for half a sand dollar given to him by Percy.[7]
Hypnos/Somnus – The god of sleep, son of Erebus, and Nyx and father of Morpheus and Clovis, the latter of whom is his demigod child in Camp Half-Blood. He has Cabin 15 at Camp Half-Blood.
Iris/Arcus – The goddess of rainbows, who administers a network of rainbows used by demigods and Olympians to communicate remotely something that is known as Iris Messaging. It's revealed that she doesn't actually handle much of the Iris Messaging system personally, instead delegating it to her cloud nymph assistant Fleecy. While Iris Messaging works for all demigods, the Romans were unaware of it and as a result, typically don't use the system. She is the mother of the demigod Butch, who makes a small appearance in The Lost Hero, who was the company of Annabeth in finding "the boy with one shoe" which was Jason Grace. After the Second Titanomachy, she is granted Cabin 14 for her demigod children. In The Son of Neptune, she meets Frank, Percy, and Hazel on their quest in finding the missing legion's eagle and is revealed to be one of the very few gods unaffected by the growing split personality problem. She offers Frank advice about his powers and has Fleecy help the Romans send an Iris Message for the first time. She is also mentioned to be an old friend of Chiron's in The Sea of Monsters and allows him to listen in on Percy and his friends communications, enabling Chiron to rescue them from trouble just in the nick of time. In The Trials of Apollo, Triumvirate Holdings use Harpocrates to block demigod communications, including Iris Messaging as part of their plans. After Harpocrates' death in The Tyrant's Tomb, Iris Messaging is finally restored to a degree, allowing Apollo to use it as part of a ceremony to summon Diana for help. However, as revealed in The Tower of Nero, communication still remains spotty a month later as the block slowly fades and Iris Messaging is still down between the East and West Coasts of North America due to the distance. In The Sun and the Star, taking place two months later and three months after Harpocrates' death, Iris Messaging has finally been fully restored.
Janus – The god of gates, doorways, beginnings, and endings; he appears as a minor character in The Battle of the Labyrinth. He has two faces, and each face seems to think the exact opposite of what the other face thinks. After harassing Annabeth Chase, he is sent away by Hera. In Percy's dreams, he learns that Janus had influenced Daedalus to allow his nephew Perdix to die.
Kymopoleia – The goddess of sea storms and daughter of Poseidon. She is bethrothed to Briares the Hekatonkheire, whom she resents. In The Blood of Olympus, Kymopoleia works with Polybotes to hinder the demigods while sailing through the Aegean Sea after feeling abandoned by her father. She is convinced by Jason to switch sides, because she wants to be feared and respected. Together, they kill Polybotes. She is nicknamed "Kym" by Percy who attempts to get her to give her husband a second chance, Percy having previously met and befriended Briares. Before they part ways, Kym gives her half-brother and Jason an important clue about defeating Gaea.
Lares – Household gods and ancestor spirits who are guardians at Camp Jupiter.

Vitellius – A Lar who is a descendant of Asclepius. In The Son of Neptune, he was first seen when Hazel was introducing Percy to him.
Morpheus/Somnia – The god of dreams and son of Hypnos. He is among the minor gods that appears as an ally of Kronos in The Last Olympian. He puts the entire city of New York to sleep during the battle. Following Kronos' defeat, Morpheus is among the minor gods that reconcile with Olympus.[7]
Melinoë – The goddess of ghosts, who lives in the underworld. She appears only in The Demigod Files in the short story "Percy Jackson and the Sword of Hades", where she scares people by showing them the ghosts of deaths they regret.[15]
Mithras - The Roman god of warriors who is mentioned by Aphrodite in The Mark of Athena when she talks about how Athena was changed by the Romans. Later, Annabeth stumbles on a cult of ghosts dedicated to him, who look down on her for being a girl. She realizes everything they are talking about from pictures, statues and the corpses of other dead children of Athena in the cult's chamber and manages to escape. In The Tower of Nero, it's mentioned that he was originally a Persian god who was adopted by the Romans. One of Mithras' sacred creatures is used by Nero who was a part of Mithras' cult when he was a Roman emperor.
Nike/Victoria – The goddess of victory who is on the Athena Parthenos in Athena's hand. Her children are in Cabin 17 at Camp Half-Blood. Leo Valdez, Hazel Levesque, Frank Zhang, and Percy Jackson meet her in The Blood of Olympus and later kidnap her as she has been driven insane by the split between the gods Greek and Roman selves, risking her giving victory to the giants instead. She is imprisoned aboard the Argo II and is tricked into giving the demigods information on the physician's cure. Leo is mentioned to have discussed his plan to defeat Gaea with her as well. After the split is healed, Leo releases her from the ship and she resumes her role as Zeus' charioteer in the final battle with the giants, proclaiming victory to the gods.
Nemesis – The goddess of vengeance and mother of the late Ethan Nakamura. After the Second Titanomachy, she is granted Cabin 16 for her demigod children. Nemesis is seen in The Mark of Athena where she gives Leo a cursed fortune cookie. In The Sun and the Star, it's revealed that she saved Nico's life when he first fell into Tartarus. She later appears alongside her siblings Hypnos and Epiales, but doesn't take part in Nyx's battle against Nico, Will, Bob and Small Bob. Nemesis is the first to turn against Nyx, declaring that she is also the goddess of balance and Nyx's actions are unjust. Nemesis helps restrain Nyx so that the group can escape, provides them with as much good luck as she can and directs them to sail the River Acheron back to the Underworld in order to escape. However, Nemesis warns the demigods that luck won't be on their side if they ever return to Tartarus, something that they are all too happy to swear that they won't do.
Palaemon – The god of sharks and one of Poseidon's lieutenants in the war against Oceanus.
Pan/Faunus – The late god of the wild and patron of all satyrs. Pan has been missing for over 2,000 years and the satyrs seek him fervently.[2] After Percy and his friends find Pan in The Battle of the Labyrinth, he dies peacefully and releases his spirit to Percy, Grover, Rachel, and Annabeth. As a result, Grover inherits some of his powers, instinctively displaying Pan's unique Panic cry to defeat an attacking army of monsters. In The Last Olympian, Grover carries on the legacy of Pan by sending teams of satyrs to clean up the world.[6]
Persephone/Proserpine – The goddess of spring and the queen of the underworld. Persephone is the wife of Hades and the daughter of Demeter and Zeus. Hades only allows her to visit Demeter in the spring and summer and remain in the Underworld in the fall and winter. She is said to be able to "soften" Hades and make him more merciful. Unlike most minor gods, she sides with Olympus during the war against the Titans.[7][15] In the film adaptation, Persephone is portrayed by Rosario Dawson.
Phobos – The god of fear. A son of Ares, Phobos appears in the "Percy Jackson and the Stolen Chariot" story in The Demigod Diaries, where he torments Clarisse along with his brother. He has the power to show people their greatest fears, but Percy and Clarisse cooperate to defeat him.[14] In The Blood of Olympus, a statue of Phobos is used by Piper to kill Mimas which fulfills the requirement of "one god and one demigod cooperating" in killing giants.
Pomona – The Roman goddess of plenty. Pomona isn't seen in person, but a statue of her speaks in The Last Olympian, becoming irritated when she is mistaken for Demeter by Percy, throwing bronze apples at Percy and Will Solace.[7]
Terminus – The Roman god of boundaries. In The Son of Neptune, Terminus is portrayed as obsessive-compulsive and obsessed with order. He guards the city limits of New Rome in the form of a number of statues of himself and often irritates Percy during his time in New Rome. When Polybotes attacks the camp, Percy convinces Terminus to help him kill the giant as a giant can only be killed by a demigod and a god working together. After defeating Polybotes, Percy smashes him in the nose with Terminus' head, causing the giant to disintegrate. Terminus subsequently relieves Percy of any further inspections by the god. In The Mark of Athena, he confronts the Argo II when it arrives. In The Tyrant's Tomb, Terminus protects his young assistant Julia during the Battle of San Francisco Bay. After Julia's parents are both killed in the attack, it is stated that Terminus intends to adopt the young girl himself.
Thanatos/Letus – The god of death and a lieutenant of Hades. In The Son of Neptune, the forces of Gaea capture Thanatos, allowing their dead allies to quickly return to life. He resumes his duties after being rescued by Percy, Hazel, and Frank.
Tiberinus – A river god who appears to Annabeth in The Mark of Athena. He guides her to the beginning of the Roman leg of her quest for the Athena Parthenos. To Annabeth, he looks exactly like Gregory Peck.
Rhea Silvia – Rhea Silvia is a former Vestal Virgin who mothered Romulus and Remus, the founders of Rome. She was made an immortal and wife of Tiberinus after she was given a death sentence for breaking her chastity vow. In The Mark of Athena, Rhea Silvia and Tiberinus give advice to Annabeth about the location of the Athena Parthenos. She is described as looking like Audrey Hepburn.
Triptolemus – The god of farming who is associated with Demeter. He was once a mortal prince who assisted Demeter after Persephone was taken to the Underworld and was eventually made into a minor god by her as a reward. In The Mark of Athena, Frank, Hazel and Nico seek him out on the advice of Hecate. Due to his hatred for Hades, Triptolemus turns Nico into a corn plant and refuses to heal Hazel's poisoning, but he eventually makes a deal with Frank to help if Frank can obtain him a new serpent for his chariot. After Frank succeeds, the god restores Nico and heals Hazel before giving them an antidote to the poison that they will have to drink to enter the House of Hades. Triptolemus then takes off in his chariot to spread knowledge about agriculture to the world.
Triton – A sea god depicted as a merman with two fishtails. He acts arrogant towards Percy, but respects Tyson.
Tyche/Fortuna – The goddess of fortune, who was awarded Cabin 19 at Camp Half-Blood after the Second Titan War. Her Roman counterpart Fortuna is celebrated by Camp Jupiter in the "Feast of Fortuna" on 24 June every year to decide what fortune that would befall the camp.
Primordial deities
The primordial deities are the deities that came before the Titans and the Olympians came into existence. Among the known primordial deities are:
Gaia/Terra – The embodiment of Earth who and the primary antagonist of The Heroes of Olympus series. Gaia is the wife of Ouranos, and mother of the Titans, the Elder Cyclopes, the Hekatonkheires, the Giants, and Antaeus. She is the grandmother of the Olympians, whose rule she resents. As of The Son of Neptune, she remains sleeping in the ground, but retains some consciousness and influence. Like Kronos, she commands an army of mythological figures and monsters dissatisfied with the Olympians. During The Blood of Olympus, she is defeated by Leo Valdez, Piper McLean and Jason Grace who lift her into the sky, charm her to sleep and then incinerate her with a mighty blast of fire combined with a shot from an onager by Octavian, a legacy of Apollo and the former augur of Camp Jupiter. As a goddess, she can't be killed, but her essence is scattered so much she will never able to form a consciousness again, suffering the same fate as her son Kronos.
Ourea – The primordial gods of the mountains and the children of Gaea. In The House of Hades, there were some Ourae that make up the Apennine Mountains. When the Argo II tries to cross the Apennine Mountains, the Ourae there attack them with boulders because they are loyal to Gaea. They hurl boulders from their mountaintops where they severely damage the Argo II. Leo Valdez has to turn the Argo II away from the Apennine Mountains to come up with a different plan.
Akhlys – The goddess of misery, and a daughter of Chaos and Night. She is described as a miserable-looking old woman who carries the Aegis shield with Medusa's head carved into it. In The House of Hades, she offers the Death Mist to Percy and Annabeth, but later betrays them by luring them into Nyx's territory and trying to kill them with poison. In anger, Percy manipulates the poison back at Akhlys, causing her to run away in fear. This is the first time that Annabeth sees the darker part of Percy's personality.
Keto – A primordial sea goddess and the sister and wife of Phorcys. In The Mark of Athena, Keto appears as a girl named "Kate" who is encountered in Phorcys' aquarium in Atlanta. When Gleeson Hedge discovers Phorcys' ruse, he frees Percy and Frank after knocking "Kate" out. After Percy, Gleeson, and Frank escape from the aquarium, Keto sends a skolopendra (shrimp monster - one of her children) after them.
Nyx – The primordial goddess of night, said to be the oldest being in the universe besides Chaos itself. In The House of Hades, Percy and Annabeth accidentally wander into Nyx's territory and try to pose as tourists guided by a brochure that does not mention Nyx. Angered, Nyx shows just how important she is and summons her children, who emit pitch-black darkness that even Nyx herself cannot see through it. Before she can catch them, the couple leave through the Mansion of Night. In The Sun and the Star, taking place over a year later, Nyx works to force Bob the Titan to turn back into Iapetus and seeks to lure Nico di Angelo into Tartarus to stay, believing that he belongs there due to his own inner darkness. To this end, Nyx works to use Bob's distress call to Nico to lure him back, having briefly met the demigod during his first trip into Tartarus and she creates a number of cacodemons out of Nico's darkness. Nico and his boyfriend Will Solace manage to free Bob and confront Nyx and her children Nemesis, Hypnos and Epiales. After Nico rejects Nyx's manipulations and releases the cacodemons - symbolically letting go of his own demons in the process - Nyx's children turn on her and restrain the goddess for Nico's group to escape with Hypnos going so far as to burn down her home. Although Nyx breaks free and follows them, she is unable to cross the River Acheron due to being full of pain. Weakened and injured, Nyx is forced to retreat, allowing the demigods to escape from Tartarus with Bob and his pet saber-tooth cat Small Bob.
Ouranos – The embodiment of the sky, who is the husband of Gaea and the father of the Titans. When Gaea gave birth to the Elder Cyclopes and the Hekatonkheires, Ouranos hurled them into the pits of Tartarus because of their ugly appearances. Kronos later castrated Ouranos before cutting him to pieces. Ouranos then cursed Kronos, stating that his child would come to overthrow him just as he had. Not much is mentioned about Ouranos afterwards. In Percy Jackson's Greek Gods, Percy Jackson describes Ouranos to be tall and muscular with long dark hair and his skin changing depending on if it is day or night. In The Blood of Olympus, its revealed that like his wife Gaea and his son Kronos, his essence is scattered so much that he will never able to form a consciousness again. However, in The Hidden Oracle, Apollo states that he can see Ouranos' sleeping face in the sky.
Phorcys – A primordial sea god and the brother and husband of Keto. In The Mark of Athena, he and Keto run an aquarium in Atlanta, Georgia which contains many rare sea monsters. Following a "VIP" tour, Phorcys traps Percy and Frank (who had turned into a golden koi fish) in a tank to fight each other. This attracts the attention of Gleeson Hedge, who manages to break the glass tank as they escape promising to return and free the sea creatures that Phorcys has in captivity.
Styx – The primordial river goddess of the same name. Taking oaths under Styx' name binds people into a contract; breaching them will mean consequences, oftentimes misery, for them. While multiple people have sworn under Styx' name, Styx herself does not appear until The Dark Prophecy, where she appears in Apollo's vision threatening him with punishment for breaking his oath of not playing music or practicing archery until he regains his immortality. In The Tower of Nero, she appears to Apollo after he defeats Python and asks if he has learned his lesson. Apollo finally realizes that the constant disasters that he had attributed to Styx were actually caused by himself while she had only appeared to berate him for his recklessness in each case. Styx is pleased that Apollo has learned his lesson and vanishes, telling him to hold on to what he has learned.
Tartarus – While Tartarus is the name of a location where the Titans were imprisoned, there is a primordial god by that name as well. Through Gaea, Tartarus fathered Typhon and the Giants. His real form is the whole Tartarus itself, but he personifies himself in a form that stands several feet tall with a face of a swirling vortex and a voice that makes it seem going inward, rather than outward. In The House of Hades, the personification of Tartarus appears in physical form where he makes a remark about Gaea's awakening. Annabeth and Percy fight Tartarus until Iapetus (Bob) and Damasen sacrifice themselves so that Percy and Annabeth can get out of Tartarus. In The Tower of Nero however, Nico comes to suspect that Iapetus at least survived and that he has been calling out to him from Tartarus for help. In The Sun and the Star, Nico and his boyfriend Will Solace learn that while both Iapetus and Damasen perished fighting Tartarus, they were allowed to regenerate rather than the primordial god destroying them utterly as was previously feared. Although Damasen is still reforming, Nico and Will manage to rescue Iapetus who has been imprisoned by Nyx within Tartarus.
Titans
The Titans are the children of Gaea and Ouranos. Most of them fought against the Gods during the Titanomachy which ended with the Gods winning. Among the featured Titans are:
Kronos/Saturn – The king of the Titans, the Lord of Time, and the main antagonist of the Percy Jackson and the Olympians series. He is the father of all the elder Olympians, as well as Chiron. He fights with a scythe with a six-foot-long magical blade that can harm both gods and mortals and was used to dismember his father Ouranos.[6] Kronos is initially trapped in Tartarus, but eventually escapes to possess Luke Castellan. In this form, he personally leads the Titan army against Olympus. He is finally defeated by his own host, in fulfillment of the first Great Prophecy. However, Hermes states that Kronos can't be killed and is instead scattered so thin that he hopefully can never form a consciousness again, the same fate that later befalls his mother Gaea.[7] In The House of Hades, the Titan Koios echoes this, telling Bob that while bits and pieces of Kronos' essence still remain, it is nothing that can ever be put back together again even with the help of the healing powers of Tartarus on monsters. In Percy Jackson: Sea of Monsters, Kronos is voiced by Robert Knepper. He was shown to have a gigantic, demonic body along with superhuman strength and the ability to use parts of his own body as projectile weapons. In the TV series, Kronos is voiced by Nick Boraine. His voice was heard in Percy's dreams.
Rhea – The queen of the Titans, and the mother of the elder Olympians. Unlike Kronos, Rhea loved the children that she gave birth to and even kept Zeus from being eaten. Since Kronos' defeat, Rhea retreats to Upstate New York, but continues to keep in touch with her children. In The Hidden Oracle, Apollo learns that an oracle that Rhea created called the Grove of Dodona is the only one yet to be conquered by Nero. Rhea subsequently appears to Apollo to offer him advice. In The Chalice of the Gods, Zeus hosts a brunch for Rhea on Olympus, forcing Percy Jackson to sneak in and return Ganymede's chalice to him. It's mentioned that before the brunch, Rhea had not been on Olympus in a long time.
Aigaios – The partner of Oceanus who assists in the Titans' War against Poseidon. In The Titan's Curse, Tyson reports that Aigaios protected the Princess Andromeda (a cruise ship carrying the Titan Army) from Poseidon's wrath.
Atlas – The general of the Titan army. He is the father of Calypso and the five Hesperides, one of them being Zoë Nightshade, who is later disowned because she helped Hercules steal the golden apples. Atlas was imprisoned on the mountaintop of Mount Tamalpais near San Francisco, forever cursed to hold up the sky. He is extremely powerful and strong, even for a Titan. He served as the primary antagonist in The Titan's Curse, but is mocked by the other Titans in later books for his failure.[12] He does not participate in Kronos's final assault as Luke and Kronos opted not to release him for his failure.[7]
Helios/Sol – The Titan of the Sun and the grandfather of Medea. In The Titan's Curse, Apollo mentions that Helios and Selene faded when the Romans took over and his role was given to him. In The Burning Maze, Medea summons her grandfather from the depths of Tartarus so that she can absorb his power alongside the essence of Apollo and make Caligula the new God of the Sun. Helios is summoned again to fight Apollo, Piper, and Meg. When Medea is defeated, Helios goes supernova. When Apollo encounters Helios in the burning maze, Apollo promises to free him from Medea's control in exchange that he lets them pass. After Piper kills Medea and frees Helios from his prison, Apollo persuades Helios to hold his rage and finally rest while planning to keep his memories alive.
Hyperion – Titan of the East. Hyperion is the father of Helios and Selene, the Titans of the sun and moon, respectively. He appears in The Last Olympian, where he is clad in full golden armor and battles Percy. He has all the powers of the Sun. Grover Underwood traps Hyperion by turning him into a tree.[7] In The House of Hades, Hyperion is stopped from reforming in Tartarus by his brother Bob the Titan, his tree having apparently died which sent him back to Tartarus. He and Krios are seen later guarding the Doors of Death. Both are obliterated by the physical form of Tartarus as a show of power.
Koios – Lord of the North. In The House of Hades, Koios is briefly seen in Tartarus. He mentions that his daughter Leto had been mistreated by Zeus after "she bore him those fine twins" (a reference to Apollo and Artemis). Percy describes Koios as having Apollo's smile and Artemis's eyes.
Krios – The Titan of Stars and constellations and Lord of the South. Percy first sees Krios in a dream during The Last Olympian. He wears armor decorated with glowing stars. In The Lost Hero, Jason claims to have defeated Krios in single combat on Mount Othrys (located on Mount Tamalpais in San Francisco) at the same time of the events happening in The Last Olympian. In The House of Hades Krios is seen with Hyperion guarding the Doors of Death. Both of are obliterated by Tartarus's physical form.
Leto - The mother of Apollo and Artemis. In The House of Hades, Koios suggests that she may have been destroyed and sent to Tartarus at some point as he expects her to have finally reformed by now which takes longer for the peaceful Titans. In The Dark Prophecy, Lester has a vision of Leto begging Zeus to lift Apollo's punishment and allow him to return to Mount Olympus. Zeus refuses stating that Apollo's real test is yet to come.
Oceanus – The Titan of the Ocean. Oceanus is depicted as having the upper body of a muscular man with a long beard and horns and serpentine lower body. He did not fight the Olympians in the original Titanomachy. In The Last Olympian, he assaults Poseidon's forces underwater. Oceanus is incredibly powerful and his intense battle with Poseidon lasts for days and creates storms and tsunamis. After the defeat of Kronos, Oceanus escapes back to the depths of the ocean.[7]
Prometheus – The Titan of Forethought. Like Oceanus, Prometheus prefers to fight for the more powerful side. He supported the Olympians in the first Titanomachy, but joins with Kronos in the second in part because of Zeus's cruel punishment for Prometheus's gift of fire to mankind and a foresight that the Titans would win. This punishment ended only with the Hero Hercules, a fact Prometheus uses to justify his claims to love Heroes. He is sent to negotiate Percy and Thalia's surrender during the Battle of Manhattan, offering them the spirit of Elpis (goddess of hope). He flees after Kronos's defeat, sending a list of excuses to Mount Olympus. Hermes tells Percy that if Prometheus is smart, he won't show his face again for another few centuries.[7]
Selene/Luna - The Titan of the Moon and the sister of Helios. In The Titan's Curse, Apollo mentions that due to the neglect of the Romans, Helios and Selene were eventually forced to give up their roles to Apollo and Artemis before the two eventually faded from existence. In The Tyrant's Tomb, Apollo is surprised to learn that Ida is a legacy or descendant of Luna due to his belief that the Titan had faded long ago. However, Apollo remembers that he'd thought the same thing about Helios whom he had recently encountered in the Labyrinth after Medea had resurrected the Titan.
Gigantes
The Gigantes (also called the Great Giants) are giant-like beings that were made by Gaea and Tartarus to overthrow Olympus. They were previously defeated by the gods and Heracles during the Giantomachy. Each was meant to oppose a specific god. They can only be defeated by a god and demigod working together. Most of the Gigantes are described as being very tall with dragon-like legs and shaggy hair.
Alcyoneus – A 40ft. Gigantes with rust-colored legs whom Hazel Levesque almost resurrects during World War II. Hazel sacrifices herself to stop his resurrection, but she only delays it until the 1980s. Alcyoneus eventually rises in The Son of Neptune. He is invincible as long as he remains in his homeland which after his resurrection is Alaska. Frank, Hazel, and Arion drag him into Canada where Alcyoneus is decapitated by Hazel after being made vulnerable. He is the bane of Hades/Pluto.
Clytius – A 20ft. Gigantes with ash-colored legs. He opposes Hecate. Clytius appears in The House of Hades. He guards the living side of the Doors of Death in Epirus. He is defeated by Hecate, Jason, Leo, Piper, Nico, Frank and Hazel.
Damasen – A 20ft. peaceful Gigantes with red legs who appears in The House of Hades. He had been made to oppose Ares/Mars. Damasen had been exiled to Tartarus as he was peaceful not violent and for refusing to take part in the ancient fight against the gods and Hercules. Percy and Annabeth encounter him in Tartarus when Iapetus (Bob) brings them to his lair. When the personification of Tartarus arrives near the Doors of Death, Damasen confronts him with Iapetus so that Percy and Annabeth can escape back to the living world. In The Tower of Nero, Iapetus is believed to have survived his presumed demise and is calling out to Nico for help, suggesting that Damasen may have survived as well. In The Sun and the Star, it's revealed that both Iapetus and Damasen were killed in their fight with Tartarus. However, while Iapetus has reformed and is rescued by Nico and his boyfriend Will, Damasen is still regenerating over a year later and the demigods can't find any sign of him as a result, although they spend the night in his abandoned hut.
Enceladus – A 30ft. Gigantes with green legs. Enceladus was the first Giant to be reawakened in the Heroes of Olympus series. He opposes Athena/Minerva.

Ephialtes and Otis – Twin 12ft. Gigantes that look somewhat more human than most of their brothers since they each have two snakes for legs, which are usually hidden under their black pants. They both oppose Dionysus/Bacchus. Ephialtes and Otis are awakened in The Mark of Athena by Gaea. Ephialtes and Otis manage to capture Nico and were tasked by Gaea to kill all demigods of prophecy but two, whom they are to bring to her. They fight Jason and Percy who defeat them with the help of Bacchus. In The House of Hades, Ephialtes and Otis return to the living world through the Doors of Death.

Demigods
The following demigod characters all have one parent who is a Greek or Roman god (or, more rarely, a Titan), while the other parent is a mortal human. It is common for these "half-bloods", as they are known, to grow up unaware that they are not entirely human. They are frequently referred to by gods and other mythological beings as "mortals".
Alabaster Torrington – A 16-year-old English American demigod son of Hecate, Alabaster appears in the short story "Son of Magic" in The Demigod Diaries. Due to being Hecate's son, he is the half-brother of the murderous monster Lamia. Alabaster allied with Kronos during the Titan War in The Last Olympian and was sent into exile after the Titan War after refusing to stay at Camp Half-Blood. He claims to have led his siblings to their deaths during the war against the Olympians. Alabaster's powers include the ability to cast protection spells for himself, the ability to track other people, the ability to remove a spell from another person, and the ability to control the Mist, which allows him the ability to manipulate the memories and perceptions of those who cannot see through it.[16] Alabaster is the only canon demigod in any of the series to not be created by Rick Riordan and was instead created by Rick's son Haley.

In The Tower of Nero, he participates in the final battle with the Roman emperor Nero. Austin's main power is a form of musical audiokinesis. He can use his musical abilities to heal (via his singing voice) and put curses on (Austin is able to put week-long curses on people that make them only able to talk in rhyming couplets) others and possesses an aptitude for music higher than even most his fellow children of Apollo. Miles mainly plays jazz music and is an excellent saxophone player who is also proficient (though not to the same extent) at the violin.[11] In addition to his musical abilities, Austin, like many children of Apollo, is very skilled at archery.
Bianca di Angelo – A twelve-year-old daughter of Hades and the older sister of Nico. Percy, Annabeth, Grover, and Thalia rescue her and Nico along with the help of the Hunters of Artemis from Westover Hall and the manticore Dr. Thorn.

While inside the Labyrinth, Chris was driven insane by the Ghost King Minos, but is rescued by Clarisse (who has feelings for him) and is taken back to Camp-Half Blood. In The Battle of the Labyrinth, Dionysus uses his powers to restore Chris' sanity and Chris begins dating Clarisse after the two bond when she takes care of him during his recovery from the Labyrinth. In The Last Olympian, Chris fights with Clarisse and the rest of the camp in the Battle of Manhattan.[7] Chris is noted to be a very capable fighter, having been selected by Kronos' forces to travel through the highly dangerous and complex Labyrinth alone and being one of the best fighters at the Battle of Manhattan. Chris likely possesses the standard abilities of a child of Hermes and is specifically known to have the ability of clauditiskinesis, or the ability to sense and control the internal structure of any lock he comes across, even being able to manipulate a lock telepathically if he concentrates hard enough. In the film adaption of Sea of Monsters, Chris Rodriguez is portrayed by Grey Damon. In the TV series, he is portrayed by Andrew Alvarez.[18]

Connor Stoll – Connor and his brother Travis serve as lead counselors of the Hermes cabin after Luke's departure. The Stolls are known to be crafty and mischievous, like their father.[12] They are tall and thin, with stringy brown hair. Both survive the Titan war. In The Hidden Oracle, Connor becomes the sole counselor due to Travis attending college, something that he still has not gotten over with. He picks on Meg after the latter pokes him in the eyes.
Dakota – A son of Bacchus at Camp Jupiter known for his borderline-addiction to extra-sugary red Kool-Aid. He was both a centurion of the Fifth Cohort and a senator, known for often being on a sugar high. Despite his frequent states of hyperactivity, Dakota is still often shown to be a capable leader and friend in both, such as being one of the first people to accept Percy into life at Camp Jupiter instead of treating him with contempt and suspicion and being one of the first Roman officers to defy Octavian's orders in The Blood of Olympus and choosing to side with Reyna and her attempts to de-escalate the conflict between Camp Half-Blood and Camp Jupiter. In The Tyrant's Tomb, he is mortally wounded during the Battle of San Francisco Bay and later dies of his injuries. His funeral pyre is scented with Kool-Aid in honor of his love for it. In The Sun and the Star, Will Solace fondly remembers Dakota clumsily trying to help out in the infirmary after the final battle with Gaea. Dakota possessed the standard abilities of a child of Bacchus, such as chlorokinesis (the ability control plants) and the ability to either induce or cure madness in an individual and is a excellent fighter, holding his own against Jason Grace.
Damien White – A son of Nemesis. He has a heated rivalry with Chiara Benvenuti, although Apollo hints that the two are in a relationship at the end of The Hidden Oracle.

Georgina – A maybe daughter of Apollo who was adopted by Hemithea and Josephine and raised at the Waystation. At age seven, she started to show signs of her father's powers when the Oracle of Trophonius entranced her. She was kidnapped by Commodus before the events of The Dark Prophecy. Apollo frees her and realizes that she might be a daughter he does not know about.
Gwendolyn (Gwen) – A centurion of the Fifth Cohort at Camp Jupiter. Gwendolyn is killed in The Son of Neptune but comes back to life because of Thanatos's capture. Her return prompts Mars to appear at Camp Jupiter and explain the circumstances of Thanatos's absence. She retires as centurion the day after because she decided to attend the college in New Rome and was replaced by Frank Zhang. It's suggested that her death was because she was murdered by Octavian, but this is never confirmed.
Harley – A son of Hephaestus, first seen in The Lost Hero. He is eight years old at the time of The Hidden Oracle, but very muscular. Harley has been trying to locate Leo, his older half-brother, with a magical beacon ever since his disappearance in the aftermath of the Second Gigantomachy.[11]
Holly and Laurel Victor – Holly and Laurel are a pair of sisters and daughters of Nike. As per their upbringing, they are very competitive and refuse to be made second, hence why they are placed as co-counselors of the Nike's cabin, otherwise, as Kayla puts it "they would've taken over the camp by now and proclaimed a dictatorship". Apollo describes them as looking like the "gorgeous, ferociously athletic African nymphs" that he and Artemis used to hang out with at Lake Tritonis.
Jacob – Jacob is the legion Aquilifer (which is an eagle bearer) of Camp Jupiter. His godly parent is unknown. In The Tyrant's Tomb, he is killed during the Battle of San Francisco Bay.

Michael Kahale – A son of Venus and a centurion of the First Cohort at Camp Jupiter. Michael is Native Hawaiian. Michael is one of Camp Jupiter's greatest fighters and possesses the powers of amokinesis (which allows him to control love, lust, and beauty), beauty radiation (this ability is shown to actually be a major asset in battle and combat as it prohibits his enemies from attacking him even to counter his own attacks), and most notably superhuman strength, with Reyna noting that his strength is on a comparable level to both a Laistrygonian Giant and a Cyclops. Michael is shown to be very loyal to Octavian due to the latter being his sponsor, although he is shown to often be conflicted in complying with Octavian's more questionable decisions, a reluctance that increases as Octavian's actions bring Camp Jupiter closer and closer to war and unnecessarily jeopardizes the safety of both camps. In The Blood of Olympus, he reluctantly follows Octavian's order to attack Camp Half-Blood, but his loyalty to Octavian finally ends when he chooses to allow Octavian to die when the latter ignites an onager with his feet being tangled with it. In The Tyrant's Tomb, he is said to have been sent on a failed quest to stop the emperors' yachts, although it is currently unknown if he lived or died. He is later mentioned by Will in The Sun and the Stars, when Will recalls that he, Nico, and Michael did not attempt to stop Octavian from accidentally getting himself killed, although Will does not mention if nor does he imply that Michael is either alive or dead.
Michael Varus – A son of Janus and a former praetor of Camp Jupiter in the 1970s. He was killed by Alcyoneus during an expedition in Alaska and the eagle of Camp Jupiter was stolen with him. This tarnished the reputation of Varus' cohort, the Fifth, which was not recovered until Jason's promotion to praetor over three decades later. Varus' ghost appears to attack Percy in The Son of Neptune and again in The Blood of Olympus where he confronts Jason with his mother's mania and then mortally wounds him with an imperial gold sword.
Michael Yew – Michael Yew succeeds Lee Fletcher as head of the Apollo cabin. He is described as very short, with a face that reminds Percy of a ferret. In The Demigod Files, in an interview with Clarisse, she mentions that she would want to pulverize Michael, thus stating that they are enemies. He is an excellent archer like most of Apollo's children and uses sonic arrows which were given to him by his father. He was presumed killed after leading a group of demigods in the fight against Kronos's army; Percy found his bow, but not his body.[7] In The House of Hades, he's mentioned as having died. In The Sun and the Star, Michael appears to Will in a nightmare of the Battle of Manhattan caused by Nyx.
Miranda Gardiner – Miranda is second in command of the Demeter cabin in The Lost Hero. She assumes the head counselor's duties in the winter when Katie Gardner hibernates.[citation needed] In The Hidden Oracle, Miranda is the third to be kidnapped during Nero's spree in luring Apollo, which greatly disturbs Chiron due to her important status as counselor, though Apollo manages to rescue her. She is dating Sherman.

Olujime – Olujime, also known as Jamie (and Jimmy in the eBook edition), is a demigod that worked as a mercenary for Commodus in The Dark Prophecy. Olujime is a young YorubanNigerian man, with his heritage being shown through his usage of the Yoruban and Hausan martial arts Gidigbo and Dambe. Jamie is a graduate student at Indiana University, where he is studying to earn his graduate degree in accounting, with it being revealed that the reason he began working as a mercenary for Commodus was to financially support himself. Sometime after becoming a mercenary, Olujime had a falling out with his employer which led to Commodus imprisoning Jamie out of fear of the latter betraying him. Jamie would turn against Commodus when he was freed from his prison by Apollo and assisted Apollo in defending the Waystation. Through his turning on his former employer and his subsequent interactions with Apollo, Olujime is shown to ultimately be a good and kind man who was simply down on his luck and redeems himself by helping in the defense of the Waystation. Jamie states that he has an unnamed girlfriend, much to the dismay of Apollo, whom had grown attracted to him. Jamie is notable for being the first demigod to appear in the series to not be Greek, Roman, or Norse (the Egyptian gods in the Kane Chronicles do not sire children with mortals, therefore there are no Egyptian demigods in the continuity of the series) and is instead a Yoruban demigod with powers of electrokinesis, which are revealed when he uses in the battle of the Wavestation. Due to their shared abilities of electrokinesis Olujime's fighting style reminds Apollo of the fighting styles of Zeus and/or Jupiter, although his usage of Yoruban and Hausan/non-Greco Roman martial arts and fighting styles, along with the different coloration of Olujime's electric powers and the electric powers of Zeus's children (The powers of Zeus and his children are consistently depicted as bright gold, while the powers of Olujime are depicted as having a red coloration) make Apollo and Zeus daughter Talia Grace recognize that Jamie is not a demigod of Greek or Roman origin and is instead from a separate pantheon entirely. Olujime's exact godly parentage is unknown, but it is very likely that he is the son of the Yoruban OrishaShango, who in the Yoruban religion has control over thunder, electricity, and lightning. Additionally tying Jamie to Shango are the red coloring of his powers, with red being a color often associated with Shango, their common usage of an ax, and the red and white necklace that Olujime wears (white, liked red, is another color associated with Shango).
Paolo Montes – A son of Hebe from Camp Half Blood who first appears in The Hidden Oracle. He is Afro-Brazilian and speaks mainly in Brazilian Portuguese, but understands English. In addition to the standard youth manipulation powers that a child of Hebe possesses, Paolo has vitakinesis power that enable him to heal himself from incredibly gruesome injuries, to the extent that he is shown to be capable of mending numerous amputated limbs back to full functioning capacity in a short time. Paolo again appears in Camp Half-Blood Confidential with his fellow campers discussing curses. He is briefly mentioned in The Sun & Stars by Will Solace, where Will mentions that he still attends Camp Half-Blood and was one of the demigods inspired by Nico coming out.

William H. Seward – The son of Hebe and a former Governor of New York. During the Battle of Manhattan in The Last Olympian, Annabeth Chase activated a statue of William H. Seward in Madison Square Park. It was the first statue she activated. It was a celestial bronze statue on a red marble pedestal. The William Seward statue was sitting on a chair, legs crossed, wearing an old-fashioned suit and a bow tie and long coattails. Books were piled under his chair, and he held a writing quill in one hand, big metal sheet of parchment in the other.

Bryce Lawrence – A legacy of Orcus. In The Blood of Olympus, Bryce is seen by Reyna in a dream. Despite being banished from Camp Jupiter by Reyna years ago for having killed his own centurion, Octavian allows him to return turning a blind eye to his cruelty towards the rest of his fellow cohort when he first joined the legion. He is given his probatio necklace and is assigned to the Fifth Cohort. In South Carolina, Bryce overhears Reyna's story of killing her father, and tries to capture her and take her to Octavian to charge her with the crime of patricide. He then is turned into a ghost by Nico and forced into the Underworld.
Emily Zhang – Frank's mother, a Canadian Forces soldier who died in Afghanistan. She is descended from Periclymenus, a grandson of Poseidon, which imbues her with the ability to shapeshift.
Grandma Zhang – Emily's mother, also with her family's gift. She believes Frank should spend more time studying his Chinese heritage. Her fate is unknown after a monster attack destroys her home, but it's suggested that she may have managed to escape by shapeshifting into a bird.
Julia – A little girl who is the descendant of an unspecified god. In The Son of Neptune, she works as Terminus' helper at the security checkpoints at the New Rome town line. She often hides playfully underneath Terminus' statue base. Her parents died in The Tyrant's Tomb and Terminus adopted her in the end of the book.
Octavian – Octavian is ambitious and cunning. He describes himself a descendant of Apollo in The Son of Neptune but Rachel calls him "son of Apollo" in The Mark of Athena. He reads the auguries for Camp Jupiter. He is thin and blonde. He is also said to "look eighteen but could probably pass as younger". After seeing Octavian and Will Solace - a son of Apollo - together, Nico describes Octavian as a watered-down, unhealthy version of Will - like a photo that had been copied too many times and without anything that makes a child of Apollo special. After Jason Grace disappears, he campaigns to succeed to Jason's position as praetor. He is suspicious of the amnesic Percy Jackson when he arrives at Camp Jupiter, deducing he is a Greek demigod, rather than Roman by calling him graceus, the Latin for "greek", mocking him and attempting to undermine his quest. It is also implied that he murders Gwen, the centurion of the Fifth Cohort. However, Gwen is quickly resurrected due to the Doors of Death being open. When demigods from Camp Half-Blood arrive at Camp Jupiter, Octavian declares the Greeks invaders and urges the Romans to fight them off, believing the Greeks to be in league with Gaea. His warmongering escalates further in The House of Hades where he violates direct orders from Reyna not to attack Camp Half-Blood after leaving for her quest to get the Athena Parthenos back to Long Island, leaving him in command of the Legion. Apollo himself shows disgust towards Octavian and his actions later on, although Zeus suggests that Apollo may have encouraged Octavian. As time goes on, Octavian's actions and behavior grow more and more insane and he eventually declares himself Pontifex Maximus. In The Blood of Olympus, he leads a siege of Camp Half-Blood with an army of Roman soldiers and allied monsters and onagers that, as revealed in The Hidden Oracle, came from the Three Emperors. Octavian's rule is eventually overthrown after a team from Camp Half-Blood sabotages his weapons and Reyna returns with the Athena Parthenos to restore order, supported by two of the legion's centurions. When Gaea rises, Octavian loses his mind completely and decides to launch an onager shot at the goddess. Nico and Will confront Octavian who fails to notice that his robes got caught in the firing ropes. Remembering Hades' wisdom that some deaths should not be prevented, Nico allows Octavian to fire, resulting in the insane Roman launching himself at the goddess as well. Octavian is killed in the explosion, but his actions are covered up and he is declared a Hero as his shot may have actually aided Leo Valdez in defeating the goddess. From Leo's perspective, he heard a comet shrieking like a little girl as it flew towards him, much to Leo's surprise and confusion. However, Nico is left worried that all he did by allowing Octavian to kill himself is to kill Leo, unaware that Leo was resurrected after the battle. In The Sun and the Star, Nico and Will both admit that they suffer from guilt over allowing Octavian to kill himself in such a manner and not trying to stop him.
Mythological figures
The following characters from Greek mythology appear in this series. Most of them are the direct children of gods or Titans, but a few are mortals with such great power that they are able to influence the realm of the gods.
Achilles – The son of Thetis and Peleus. The ghost of Achilles appears briefly in The Last Olympian, warning Percy about the Curse of Achilles.
Agamethus – The son of King Erginus and mortal half-brother of Trophonius. He was decapitated by Trophonius to spare the latter from being captured following a disastrous attempt to steal the riches of King Hyrieus. His headless ghost resurfaces to deliver baby Georgina to Hemithea and Josephine at the Waystation and later becomes a constant visitor of the sanctuary. Lacking a head, he speaks by arranging the letters of a Magic 8 Ball.
Charon – The ferryman who carries the dead across the River Styx to the underworld. Percy and his friends meet him in The Lightning Thief. He also states he does not like being confused with the centaur Chiron. He likes Italian suits. In the film adaptation, Charon is played by Julian Richings. In the musical, Charon is portrayed by Carrie Compere. In the TV series, Charon is portrayed by Travis Woloshyn.
Chrysaor – A half-giant who is the son of Medusa and Poseidon, the brother of Pegasus, and the father of Geryon. He is first mentioned in The Last Olympian when Percy and Annabeth go to see the Oracle of Delphi in the attic of the Big House. A pair of fuzzy dice is said to have been stolen from his car. In The Mark of Athena, Chrysaor and his crew attacked the Argo II in the Mediterranean with the intent to sell Piper and Hazel to Circe, kill Jason, and then give Annabeth and Percy to Gaea. Chrysaor battles Percy on the deck of the Argo II. Once Chrysaor's crew abandon him, Frank and Percy surround him. Chrysaor is knocked off the Argo II by Frank and Percy and Chrysaor falls into the sea. His ship, golden mask, and loot are claimed by the Argo II crew who then sacrifice it as an offering to Bacchus.
Circe – Circe ran a magical beauty boutique in the Sea of Monsters, where she went by the alias of "C.C.". While she treated females at her spa, she turned males into guinea pigs. When Percy was turned into a guinea pig, Annabeth used multivitamins from Hermes to restore him, and together they defeated Circe. In The Heroes of Olympus series, it is revealed that Circe employed Reyna and Hylla after they left Puerto Rico and treated them nicely, at least until the pirates were freed and proceeded to capture the sisters.
Daedalus – Architect of the Labyrinth, Daedalus is the son of Athena and the father of Icarus. He killed his nephew Perdix but escaped eternal punishment by casting his soul into automatons. Athena branded him with a murderer's brand in the shape of a partridge. In The Battle of the Labyrinth, Daedalus appears under the alias of a Camp Half-Blood worker named Quintus (meaning "the fifth" in Latin). Percy and Annabeth convince him to use his technical genius to help defeat the Titan army in the Labyrinth. He then accepts death, willing to Annabeth his laptop filled with thousands of years of notes and ideas. In death, he becomes the Underworld's architect and is allowed to visit Icarus and Perdix on weekends.[6] Annabeth subsequently puts Daedalus' laptop to great use before it is lost in The Mark of Athena. In The House of Hades, Daedalus' Labyrinth is restored by Pasiphaë, although it is stated in The Hidden Oracle to be less malevolent ever since his death. Apollo recalls that he had warned Daedalus against giving the Labyrinth its malevolent consciousness, but the inventor had ignored his warnings.
Eurytion – A son of Ares who works on Geryon's ranch. He appears in The Battle of the Labyrinth and helps Percy and Annabeth locate Hephaestus.
Halcyon Green – A son of Apollo gifted with prophecy and under "house arrest" for revealing to a young woman her fate. He gives his life to save Luke Castellan and Thalia Grace from the Leucrotae and his burning mansion in The Diary of Luke Castellan (part of The Demigod Diaries).
Heracles/Hercules – A famous Greek Hero and the son of Zeus and Alcmene. Following his death, Zeus brought him up to Mount Olympus to live with him and he is engaged to Hebe. Heracles was mentioned but did not appear in the first book series, usually when monsters that he had fought show up to trouble Percy. In The Titan's Curse, it is revealed that Zoë Nightshade helped Heracles steal the Apples of the Hesperides and gave him a magical sword Riptide which he had forgotten to return, leaving her to be disowned by her sisters and him giving her no credit for her help. Hercules appears in The Mark of Athena where he was tasked by Zeus to guard the Pillars of Hercules and issues Piper and Jason a quest for permission to enter the Mediterranean Sea, having them steal Achelous' other horn for him although Piper chooses to keep it for herself. In The House of Hades, the giant Clytius reveals that Hercules and Dionysus, both then very powerful demigods well on their way to becoming gods, had helped Hecate to defeat him the first time.
Hyacinthus – Hyacinthus was a beloved lover of Apollo. The right for him was contested between Apollo and Zephyrus, and when the former refused to share, Zephyrus caused an accident that led to Apollo's accidental killing over Hyacinthus. His death is regarded by Apollo as one of his two greatest losses of his life, together with Daphne's petrification. Upon his death, Hyacinthus was reincarnated as a hyacinth. To this day, Apollo is still haunted by visions of him.
Irus – A beggar who ran afoul of Odysseus upon his return to Ithaca. In The Blood of Olympus, Jason posed as Irus to get close to the ghosts of the Suitors of Penelope.
KingMidas – A king who possessed the golden touch which turned anything he touched to gold. He is among the people brought back to life by Gaea in The Lost Hero where his Golden Touch was restored upon him and his son Lityerses emerging from the Doors of Death. It has been mentioned that Midas has occasionally turned Lityerses to gold by mistake causing him to use the nearby lake to wash the gold off of him. Jason, Piper, and Leo come to Midas's mansion in Omaha, Nebraska. He was initially polite before revealing his allegiance and turning Leo and Piper into solid gold. Jason fought back against Midas and Lityerses and managed to restore Leo and Piper to life along with his other victims. Midas is left at the mercy of his freed victims and it's confirmed in The Dark Prophecy that he was sent back to the Underworld.
King Minos – A former king who becomes one of the judges of the Underworld. Nico consults him in The Battle of the Labyrinth, but Minos kidnaps Nico and tries to kill Daedalus who constructed the Labyrinth for him. Fighting back, Nico banishes Minos back to the Underworld. When Daedalus later ends up in the Underworld, Minos tries to convince the other two judges to punish Daedalus to no avail.[6]
King Sisyphus – A former ruler of Corinth. He had committed violations of guest hospitality, seduced his niece, plotted to kill his brother, Salmoneus, and told the river god Asopus where Zeus had his daughter. His major crimes involved cheating death twice. The first where he tricked Thanatos into showing him how the chains worked causing Thanatos to be trapped until Ares freed him (Thanatos being trapped displeased Ares since no one in battle could die). The second time was when he complained to Persephone that his wife Merope did not give him a proper funeral and sent Sisyphus' spirit to the living. Even when Sisyphus did not want to return to the Underworld, he was forcefully dragged back there by Hermes. His punishment in The Fields of Punishment was to push a boulder up a hill. When it got close to the top, the boulder would roll back to the bottom and Sisyphus was condemned to begin again. He appears in The Demigod Files in the story titled The Sword of Hades when Percy and Nico asked his advice while Thalia pushes the boulder up the hill. He does not really help them much, but he does say that he helped someone else. He said that he told that other person to go see Melinoe. Therefore, Percy and his friends go to see Melinoe as Sisyphus begs for them to set him free from his punishment for being here was a minor set-back.[15]
King Tantalus – The spirit of a king from the Fields of Punishment who is the son of Zeus. He ended up there after killing his son Pelops, cutting him up, and serving him as food to the gods. His punishment in the Fields of Punishment was to stand under a fruit tree in the middle of a lake. When he tried to pluck the fruit to eat, the branches of the tree rose out of his reach and when he bent down to drink the water, the level would retreat. Tantalus became "tantalised" by having food and drink close to him, but unable to enjoy either. He becomes the activities director at Camp Half-Blood after Chiron is fired. He appears in The Sea of Monsters as a minor character. Even when hired as the activities director, he could not eat or drink as the food kept evading him. Tantalus is shown to hate Percy and his friends even more than he hates most half-bloods, yet shows favoritism to Clarisse, as when naming her Hero when the camp was attacked by Colchis Bulls or when she wins the chariot race and throwing a banquet in her honor. When Tyson is brought to camp, Tantalus insults and makes fun of him even when Tyson is claimed by Poseidon. When the camp is attacked by a large flock of Stymphalian birds, Tantalus blames it on Percy, Annabeth, and Tyson's "bad chariot driving" despite that they were the ones who defeated the birds. At the end of the book, his curse is lifted by Dionysus just before he is sent back to the Underworld as he attempts to take some food along. None of the campers are sad to see him go. In the TV series, Tantalus will be portrayed by Timothy Simons.[19]
Lityerses - The son of King Midas who is nicknamed "Lit". In The Lost Hero, he and Midas emerged from the Doors of Death and were resurrected. After King Midas turns Leo and Piper to gold, he has Lityerses fight Jason before Midas can turn him to gold. After Jason defeats Lityerses, King Midas tries to help him only to accidentally turn him to gold. After throwing a rug over Lityerses, Jason summoned a thunderbolt that caused rain to come down on those who had been turned to gold, leaving Lit trapped as Midas was killed by his freed victims. By the events of The Dark Prophecy, Lityerses is freed from his golden form by Commodus and goes to work for him. He later defects to the side of the Waystation's inhabitants and helps to defeat Commodus' attack. Lit subsequently decides to settle at the Waystation and protect it from further harm. In The Tower of Nero, he continues to live at the Waystation and is stated to be adjusting well and to be heading up an elephant visitation program with Camp Jupiter.
Medea – A sorceress and a granddaughter of Helios. Jason, Piper, and Leo encounter her in The Lost Hero, where she runs a mall in Chicago under the name "M" after being resurrected by Gaea through the Doors of Death. She becomes enraged upon learning Jason's name which he shares with her former husband, the Hero that recovered the Golden Fleece who left her. Her magic causes Jason and Leo to become hostile to one another. Realizing Medea is an agent of Gaea, Piper brings them to their senses and leads their escape before Medea can do anything else to them. In the process, Medea's mall is destroyed and she is killed in the explosion. Aphrodite later warns Piper that Medea will eventually return along with others due to the Doors of Death being opened by Gaea's forces. In The Burning Maze, a once again resurrected Medea returns and she is now working for Caligula. When she engages Meg in a charmspeak battle, she announces her plans to take Apollo's essence, combine it with her grandfather's leftover power, and make Caligula the new God of the Sun. Medea later appears in the throne room of Caligula asking him to perform the ritual after she trapped Jason and Piper in a tornado prison. When Apollo stabs himself, Medea and Caligula rush to perform the ritual before he dies. Her being focused on the ritual weakened the tornado prison enabling Piper to punch Medea. When Apollo reaches Herophile's holding area, Medea appears and prepares to extract Apollo's essence. Piper saves Apollo by stabbing Medea and pushing her into Helios' flames.
Muses – The immortal daughters of Zeus and the Titan Mnemosyne, who inspired and preside over several creative arts. In The Lightning Thief, the Muses performed on Mount Olympus at the time when Percy returns Zeus' Master Bolt. As the gods celebrate, the Muses play music that sounds like anything you want, so no one argues about the music. In The Titan's Curse, the Muses perform their music after the Gods decide not to kill Percy and Thalia. According to Percy, everybody hears the music they only want to hear, like classical for the gods and hip hop for the younger demigods. In The Last Olympian, a few Muses are shown playing some tunes on Olympus. Their hearts were not into it because of Kronos' attack on Mount Olympus while the Gods were out fighting Typhon.
Narcissus – A hunter who was renowned for his beauty and disdained those that had loved him. Nemesis puts a spell on him that causes him to fall in love with the reflection of himself in the water where he dies upon not being able to leave his own reflection. After Gaea opened the Doors of Death, he was resurrected. In The Mark of Athena, Narcissus is encountered by Hazel Levesque and Leo Valdez at the Salt Lake in Utah where the demigods are looking for the Celestial Bronze which is needed to help repair the damaged Argo II. When Narcissus realizes that Hazel and Leo have managed to steal his bronze plate which he uses to be able to admire his own reflection, he and a mob of nymphs runs after them trying to kill them.
Oracles - The Oracles are both beings and places that can give prophecies in Greek mythology. There are five of them. Four Oracles are associated with Apollo.
Oracle of Delphi – Apollo's Oracle of Delphi resides in the mummified remains of its host, until its power was transferred to Rachel Dare in The Last Olympian. At the end of World War II, the Oracle issued the Great Prophecy, saying a child of the Big Three (Zeus, Poseidon, and Hades) would determine the preservation or destruction of Olympus. This caused those gods to form a pact not to father more demigods. After Zeus killed his lover Maria di Angelo as a result of the prophecy, Hades cursed the Oracle's spirit to be trapped in its host in retaliation with this curse being broken after Nico and Hades were given acceptance by the gods and Camp Half-Blood. An attempt to transfer the spirit to May Castellan while the Oracle was still cursed resulted in May's insanity.[7] Throughout The Trials of Apollo, the Oracle's power is inaccessible to Rachel until Apollo kills Python. In Percy Jackson: Sea of Monsters, the Oracle of Delphi is voiced by Shohreh Aghdashloo. In the musical, she is portrayed by Carrie Compere. In the TV series, she is portrayed by Jennifer Shirley.
Trophonius – Son of Apollo and half-brother of Agamethus, he and his brother's attempt to steal the riches of King Hyrieus ended with Trophonius reluctantly decapitating Agamethus to save himself, despite him having begged Apollo to save them. Later, he became guardian of an oracle which bears his name, reputedly the oracle that would drive its seekers into insanity unless proper rituals are conducted. Regardless of his antagonism to Apollo due to his predicament, he asks his father to destroy the Oracle and himself, so Commodus would not be able to access it again.
Pasiphaë – A Greek sorceress and daughter of Helios who appears in The House of Hades. She is resentful of the gods for punishing her by giving birth to Minotaur, while her husband, Minos, who caused the problem in the first place, enjoys the right as a judge in the Underworld for being Zeus' son. She is allied with the giants, restored the Labyrinth and enters into a battle of sorcery with Hazel who manages to drop her through a trap door into a bottomless pit using magic.
Phineus/Phineas – A blind seer who appears in The Son of Neptune. Percy Jackson finds him in Portland where the Harpies are trying to steal his food. Before he dies from Gaea making him choose the poisoned gorgon's blood from the offer Percy gave him, he reveals to Percy the location of Alcyoneus' camp. In The House of Hades, Percy experiences a curse laid upon him by Phineas' death while in Tartarus.
Procrustes – The son of Poseidon who is depicted as a half-giant and rogue thief/blacksmith who was previously defeated by Theseus. Procrustes appears in The Lightning Thief as "Crusty", a Los Angeles mattress store owner. He traps Annabeth and Grover on his beds and tries to stretch their spine. Percy traps him using Procrustes' own stretching equipment and then decapitates him with Riptide. In the TV series, Procrustus is portrayed by Julian Richings.
Sciron – A thief and son of Poseidon. He had previously fought Theseus in the past. In The House of Hades, Sciron and his giant turtle waylaid the Argo II on the coast of Croatia. Like his fight with Theseus, Hazel defeated Sciron by pushing him off of the cliff where he was gobbled by the Giant Sea Turtle.
Suitors of Penelope – Men who competed to become the next wife to Penelope when they believed that she became a widow when Odysseus was fighting in the Trojan War. When Odysseus returned, his disguised appearance spoke to Penelope to hold a contest where the Suitor that can string Odysseus' bow will become her new husband. When Odysseus won the contest, he sheds his disguise and kills the Suitors with the help of Telemachus and Philoeteus. In The Blood of Olympus, Jason, Piper, and Annabeth encounter the ghosts of the Suitors of Penelope on Ithaca where they are now allied with Gaea. After their true identities are revealed by the ghost of Michael Varus, the three destroy the Suitors.
Theseus – A Hero who is the son of Poseidon and younger than Percy had assumed. When Nico was trying to summon Bianca in The Battle of the Labyrinth, he ended up summoning the spirit of Theseus.
Other Greco-Roman beings
Greco-Roman humanoids
Many of the beings and creatures of Greco-Roman myths are humanoid—in other words, they possess both the intelligence and some of the physical features of humans. The vast majority of these creatures are friendly, such as nymphs and centaurs. Unlike most Greek creatures, these beings are also unquestionably sentient and tend to have larger roles in the novel series.
Agrius and Oreius – Humanoid bears that were a result of a union between a woman named Polyphonte and a bear due to the power of Aphrodite. They were also the great-grandsons of Ares due to Polyphonte being Ares' granddaughter. The two served as Luke's henchmen in The Sea of Monsters but were killed by the party ponies and Blackjack the Pegasus.
Amazons – A tribe of female warriors who usually worshiped goddesses like Hera and Artemis. Some Amazons appear in The Son of Neptune where they are sent to their compound at Reyna's request. They also run the billion-dollar Amazon.com, which they use as a source of cover and revenue. Though they are often confused with the Hunters of Artemis, the Amazons are not misandrists and like men just fine; they are just a very matriarchal society in which their male spouses are made to work in manual labor while the Amazons work as administrators. In The Blood of Olympus, the Amazons collaborate with the Hunters of Artemis to protect Reyna from Orion, resulting in many casualties.
Doris – An Amazon who is loyal to Otrera. In The Son of Neptune, she and Lulu guarded Percy Jackson and Frank Zhang.
Hylla Ramírez-Arellano – The older sister of Reyna, the praetor of Camp Jupiter; she is 22 years old. She is a demigod daughter of Bellona and the Amazon Queen. She looks a lot like Reyna with beautiful, glossy black hair and black eyes, long lashes, and a scar on her forehead. She as her sister had the bearing of a swordswoman but stronger. Hylla wears a black suit with a golden belt. Reyna describes her sister as a "chameleon" because she is always changing. They have similar personalities but Hylla seems more funny and "chill". She was born in Puerto Rico and worked for Circe during the first series with her sister. She also spent a year living with pirates and winning the crew's respect. She had an awful childhood, basically, she was always trying to protect her sister from their dad. Her father was in the army and the whole Ramírez-Arellano family was favored by Bellona. While worshiping her, Hylla's father falls in love with the idea of war and Bellona. They have the two kids together. Later, the father shows symptoms of PTSD. It turned out he had become a mania, or an insane soul with the worst qualities, and was no longer human. The mania knocks out Hylla, Reyna think she is dead and unknowingly kills her father, who was, technically, already dead. All that was left was the crazed and obsessed remnants of the soul. In The Blood of Olympus, the Amazons have been working with the Hunters of Artemis who kidnap Reyna and take her to an Amazon headquarters, where Hylla reunites with her sister. Orion breaks into the Amazon HQ and kills every Hunter and Amazon, but the girls escape to their old house, and try to defeat Orion without success. Hylla orders Reyna to leave because she had to stay in combat with the supervivients, hunters, and some Amazons. Though she is never seen afterwards, Orion later confirms that Hylla is still alive, much to Reyna's relief.
Kinzie – An Amazon who is the daughter of a nymph and is close and loyal to Hylla. She disarmed Percy and sent Frank flying across the room in The Son of Neptune. Kinzie also cornered Percy during the Feast of Fortuna and asked Percy out, though he declined. In The Blood of Olympus, Kinzie is killed by Orion.
Lulu – An Amazon guard who is loyal to Otrera. In The Son of Neptune, Lulu and Doris guarded Percy Jackson and Frank Zhang.
Otrera – A daughter of Euros and the first Queen of the Amazons who was originally killed by Bellerophon. In The Son of Neptune, she is revealed to be among those who emerged from the Doors of Death. She challenged Hylla for the title of Queen of the Amazons. When she planned to defeat Hylla, Otrera plans to have the Amazons help Gaea and the Giants destroy Camp Jupiter. Hylla manages to defeat Otrera twice until Thanatos is freed from the chains where he was trapped, making sure she would not rise from the dead and challenge her again.
Arachne – A female weaver who was turned into a spider by Athena after she got angry when Arachne won in a weaving contest against her. In The Mark of Athena, Arachne appears as a spider-like monster who is the last obstacle for Annabeth's quest to the Athena Parthenos and is in collaboration with Otus and Ephialtes. Annabeth challenges Arachne to a weaving contest where Annabeth tricks Arachne into making monster-sized Chinese handcuffs which Annabeth places onto Arachne. When Annabeth states to Arachne that the Athena Parthenos will restore Mount Olympus, Arachne goes into a fit and brings down her chamber enough to open a chasm to Tartarus. As Arachne falls down into Tartarus, she manages to ensnare Annabeth at the last minute as she and Percy go down the chasm with Nico promising to meet them at the Doors of Death. In The House of Hades, Arachne ambushes Percy and Annabeth which ended with Percy using Riptide to destroy Arachne.
Antaeus – A half-giant who is the son of Poseidon and Gaea. He was invincible as long as he maintained contact with the ground, so Percy defeated him by hanging him in the air with chains and then killing him.

Cacus – A fire-breathing giant and the son of Hephaestus. In The Demigod Diaries story entitled "Percy Jackson and the Staff of Hermes", Cacus had stolen Hermes' caduceus. He later attacked Percy Jackson and Annabeth Chase and implied that he was working for Gaea, although he didn't give her name, to shut down the gods communications. He is destroyed by Percy using the caduceus' Laser Mode, in reality a giant rocket launcher that fires energy blasts.
Centaur – Half-man, half-horse creatures, often depicted as wild and drunk. Chiron is the only truly civilized centaur. Many of his kin are part of the Party Ponies.[1][7] There are other centaurs who work for Gaea's army.

These centaurs enjoy killing demigods. In The Son of Neptune, they attacked Camp Jupiter, but most were either killed or retreated.
Party Ponies – An extended family of rowdy centaurs who reside in the United States with chapters hailing from each respective state. They are key players in two major incidents in the series. In The Sea of Monsters, they go along with Chiron and rescue Percy from Luke during their duel on the Princess Andromeda.[1] In The Last Olympian, they help Chiron and the others fight the major battle between the gods and the Titans.[7] In The House of Hades, Grover mentions that Gaea had created a stone fist to swat some party ponies, much to the confusion of Reyna.

Tyson is one of these. The third group of Cyclopes is the southern group who raise goats and live in caves. The fourth group of Cyclopes is the northern group who helped the Titans make weapons and are smarter than the southern group of Cyclopes. Some northern Cyclopes were seen fighting with Kronos' army in The Battle of Manhattan. In The Dark Prophecy, many Cyclopes were present at the rehearsal of Commodus' naming ceremony.
Grunk - A Cyclops that is loyal to Caligula. In The Burning Maze, he was seen by Apollo and Piper playing volleyball with some mortal mercenaries. Piper sings them a song to distract them so that they can get away.

Polyphemus – A cyclops of the Southern Faction. Percy Jackson and his friends encounter him on an island in The Sea of Monsters. He is shown to be blind and there was also a reference about Odysseus being responsible for blinding him under the alias of "Nobody". When Polyphemus tries to pray to Poseidon to get revenge on Percy for hurting him, Percy states that Poseidon is also his father. He later tried to eat them only for them to escape. However, Polyphemus sinks their ship in the process.

Pegasi – Winged horses that are named after the original mount of Bellerophon that was born from the blood of Medusa.
Pegasus - The original Pegasus who is the immortal father of the species. He is stated to have not been seen in person for centuries, but Pegasus comes to Reyna, Nico and Coach Hedge's aid in The Blood of Olympus, leading eight other Pegasus to help transport the Athena Parthenos. He eventually departs when the group arrives at Long Island Sound, but reveals that he came to honor Reyna's close relationship with Scipio for which Pegasus declares her Horse Friend, a high honor.
Blackjack – A black Pegasus and Percy's loyal friend. He is first introduced in The Sea of Monsters on the Princess Andromeda where Percy indirectly rescued him from Kronos's minions although Percy mistakes Blackjack for a female at the time. Subsequently, he acts as Percy's main method of transport, constantly referring to Percy as "Boss", much to Percy's annoyance. In The Last Olympian, he allows Charles Beckendorf to ride him with Percy's permission and is later hijacked by Rachel Elizabeth Dare to get to Camp Half-Blood quickly, much to Percy's annoyance. In The Blood of Olympus, Blackjack is one of eight Pegasus enlisted by the original Pegasus himself to help carry the Athena Parthenos. Blackjack acts as Nico's steed despite his previous distaste for the son of Hades and comforts Reyna. Blackjack is severely wounded by Orion, but Reyna is able to save his life and he is stated to be recovering nicely after the final battle with Gaea's forces.
Guido – A gray and white Pegasus who is friends with Blackjack. In The Last Olympian, Guido and Porkpie aided Percy and Blackjack in the Battle of Manhattan. In The Blood of Olympus, Guido is one of eight Pegasus enlisted by the original Pegasus himself to help transport the Athena Parthenos. After Pegasus' departure and Blackjack being severely wounded, he allows Reyna to ride him the rest of the way to Camp Half-Blood where she rides Guido throughout the battle with Gaea's forces. After the battle, Guido decides to adopt Reyna as his human and return to Camp Jupiter with her. However, Guido doesn't appear nor is he mentioned in The Tyrant's Tomb or The Tower of Nero which both also feature Reyna.
Porkpie – A gray and white Pegasus who is friends with Blackjack. In The Last Olympian, Guido and Porkpie aided Percy and Blackjack in the Battle of Manhattan.
Scipio – Reyna's Pegasus who appears in The Son of Neptune. His nickname is "Skippy" because he's the color of peanut butter, the same color as chestnuts. He died at the end of The House of Hades when Reyna is forced to euthanize him following Scipio's severe injuries from a griffin attack. In The Blood of Olympus, the original Pegasus honors Reyna and Scipio's great friendship by coming to her aid personally, the first time that Pegasus has been seen in centuries. As a result of how much Reyna had cared for Scipio, Pegasus declares her Horse Friend, a high honor.
Pit Scorpion – A deadly type of scorpion that appears in The Lightning Thief. When Luke brings Percy into the woods and reveals his allegiance to Kronos, he summoned a Pit Scorpion to attack Percy. He tells Percy he should not go for his sword as the pit scorpion can kill in sixty seconds and can jump up to fifteen feet. When Luke disappears, Percy manages to kill it even though it managed to sting him. Wood nymphs help Percy recover from its poison. In The Sun and the Star, a number of Pit Scorpions appear part of Nyx's army in Tartarus and fight Bob the Titan.
Scylla – One of the two monsters (the other being Charybdis) who live on either side of a narrow channel of water in the Sea of Monsters. Should a ship sail too close to her, she uses her six heads to pluck off crew members on deck and devour them. According to Clarisse (daughter of Ares), Scylla would just pick up the whole boat and crushed the boat if the crew hid below deck. In the film Percy Jackson: Sea of Monsters, Scylla was mentioned by Clarisse to have eaten Ichneutae.
Sea Serpent – A large serpent that lives in the sea. Deimos is seen riding one in The Demigod Files story "The Stolen Chariot". In The Last Olympian, a sea serpent was seen among the sea monsters in Oceanus' army.
Carthaginian Serpent – A giant serpent with a deadly venom who guards the entrance of Commodus' lair in Indianapolis.
Sirens – Dangerous bird women whose sweet songs lead many sailors to their deaths on the jagged rocks. In The Sea of Monsters, they almost killed Annabeth.[1]
Skeleton – Skeletons are the undead troops that make up Hades' undead army. In The Lightning Thief, Hades has skeletons in army uniforms guarding his palace. In The Battle of the Labyrinth, Nico manages to employ them as part of a ritual that will enable him to call the spirit of his sister to speak with her. In The Last Olympian, Nico and Hades manage to bring a troop of skeletons to help fight the Titans. They are later seen constructing a cabin at Camp Half-Blood which is dedicated to Hades. In The House of Hades, they are on the demigods side and help them in Hades's temple in Epirus.
Skolopendra – A sea monster that is 200ft. long. It looks like a cross between a giant shrimp and a cockroach with a pink chitinous shell, a flat crayfish tail and millipede-type legs. Its face is a slimpy pink like an enormous catfish with two glassy eyes and a gaping toothless maw. In The Mark of Athena, Ceto sent Skolopendra after the demigods after their escape from Phorcys' aquarium. It attacked the Argo II when Leo forgot to turn the monster-detection system on. Skolopendra withdraws into the ocean when Leo Valdez and Hazel Levesque throw test tubes filled with Greek Fire into its mouth.
Small Bob - A saber-toothed skeleton cat that is one of several that was accidentally created by Atlas' minions in The Titan's Curse while attempting to create Spartus. Atlas has the cats destroyed and they are sent to Tartarus where Percy Jackson, Annabeth Chase and Bob the Titan encounter the one that Bob names Small Bob in The House of Hades. While generally taking on the form of a small calico cat, Small Bob can grow in size to a large saber-toothed cat if he wishes to. Bob takes Small Bob as his pet throughout their journey to the Doors of Death. Small Bob is presumed destroyed at the end of the book along with Bob and the friendly giant Damasen while holding off the embodiment of Tartarus so that the demigods can escape. In The Sun and the Star, taking place over a year later, while on a rescue mission for Bob, Will Solace happens to run into Small Bob and instantly recognizes the cat from Percy and Annabeth's stories. Recognizing Nico and Will as friends, Small Bob guides them through Tartarus to his master and protects them from attacking monsters several times. He later accompanies the demigods and Bob back to the mortal world and leaves with Bob as the Titan heads west to figure out his future.
Spartus – A troop of skeletons armed with weapons. They are usually summoned by planting dragon (Sybaris) teeth in the ground and watering them with blood. In The Titan's Curse, some Spartoi ambushed Percy, Thalia, Zoe, Grover and Bianca in New Mexico. Due to her being a child of Hades, Bianca managed to destroy them. In The Son of Neptune, Frank (as a gift from his father) is given a spear with the tip of a dragon's tooth that when planted with raise one of the Spartoi, he uses this to defeat the basilisks outside of the R.O.F.L. headquarters, to kill some of the laistrygonians surrounding his grandmother's house then using his final charge to protect the mortals on a train from attacking Griffins.
Gray – A Spartus that can be summoned by Frank Zhang. He lost this ability after his spear ran out of charges.
Sphinx – A monster with the head of a woman and the body of a lion. Percy Jackson and his friends encountered the Sphinx while navigating the labyrinth. Rather than tell riddles, the Sphinx asked historical questions which Annabeth refused to answer as an insult to her intelligence. They are not to be confused with the Sphinx from The Kane Chronicles.
Strix - Owl-like creatures that eat the flesh and blood of humans. They also curse the mortals who kill them. Anyone scratched by the talons of the Strix will be paralyzed. In The Burning Maze, Apollo's Lester Papadopoulous form was chased by a flock of Strix. After one Strix gets through the tomato bomb and scratches Lester on the cheek, Grover was able to reason with it as the Strix states that it was sent by Emperor Caligula to kill them. Under the advice of the Arrow of Dardona, Meg and Grover grew strawberries to distract the flock of Strix so that they can get away. Other Strix appeared on the Julia Drusilla Yachts where Caligula uses them as surveillance. Caligula replaced the Germani with Strix and Pandai because the Germani are responsible for his mortal death.
Stymphalian Birds – A flock of Stymphalian birds attack Camp Half-Blood in The Sea of Monsters while the camp's defenses are weakened. Percy and Annabeth use Chiron's boombox and Dean Martin's "Volare" to scare them so that Apollo's cabin can shoot them down. A flock of Stymphalian Birds attack the Argo II in The House of Hades but are quickly dealt with by Festus. In The Blood of Olympus, Frank and Hazel are mentioned to have fought a flock of them on Pylos, but they are quickly dealt with by Piper shooting vegetables at them with her cornucopia. In The Tyrant's Tomb, Apollo recalls the story of Percy using music against the Stymphalian birds and uses the same tactic to scare away a flock of giant ravens. In The Demigod Files, Phobos summons them to fight Clarisse after he steals Ares' war chariot. In The Sun and the Star, Will Solace accidentally releases a flock of them from a regeneration pod in Tartarus. Will manages to stun them briefly using his ultrasonic whistle and the ones that aren't killed by Small Bob are eventually forced to flee.
Taurus Sylvestre - Also known as Forest Bulls, they are a race of cattle with red fur and blue eyes. The Taurus Sylvestre are the known enemies of the Troglodytes. If they fall into a pit, they will die from their anger leaving their hides behind. In The Tower of Nero, three Taurus Sylvestre were in the rail cars on the Dare family's property. They escaped and were chased into a construction site by Apollo, Meg, Nico, and Will. The three Taurus Sylvestre fall into a pit and die from their anger as the four look at them. Some of them later end up in the troglodyte caves. In The Sun and the Star, Nico has relocated the trogs to the Underworld due to the Taurus Sylvestre destroying their original home.
Telekhine – Dog-faced sea demons that reforged Kronos's blade in The Battle of the Labyrinth. In The Mark of Athena, some Telekhines are seen in a water tank at the Georgia Aquarium.
Trojan Sea Monster – A sea monster that rampaged the coasts of Troy until it was slain by Heracles. It is also known as the Keto Trois. In The Lost Hero, Jason Grace claims to have slain this monster while fighting Porphyrion of the Gigantes.
Typhon – A very powerful monster born from Gaea and Tartarus. He sired many monsters by Echidna. He lives and sleeps inside Mount St. Helens. In The Battle of the Labyrinth, Percy causes Mount St. Helens to erupt while trying to escape Telekhines and he inadvertently awakens Typhon in the process. In The Last Olympian, Typhon awakes and moves across America destroying everything in his path. As he is concealed in mist, Typhon's appearance is not described and appears as a freak storm. The gods of Olympus try to stop him, but he is too powerful. In the end, Poseidon and his army help to defeat him and Poseidon opened up a tunnel that sends Typhon directly into Tartarus. Once Typhon was defeated, a wave of anemoi thuellai were born.[7]
Unicorn – A horse with one horn. A herd of unicorns are used as steeds for the campers of Camp Jupiter. A red-tinted Lares with the head of a wolf guards them.
Buster - A unicorn that lives in Camp Jupiter. In The Tyrant's Tomb, Meg and Pranjai use his horn shavings to tend to the scratch on Apollo's stomach. He later joins the other unicorns in fighting the invading zombies during the second wave of Caligula's Assault on Camp Jupiter.
Horatio - A unicorn that lives in Camp Jupiter. In The Tyrant's Tomb, Horatio is among the unicorns that fight Tarquin's army during the Battle of San Francisco Bay.
Muffin - A unicorn that lives in Camp Jupiter. In The Tyrant's Tomb, Muffin is among the unicorns that fight Tarquin's army during the Battle of San Francisco Bay.
Shirley - A unicorn that lives in Camp Jupiter. In The Tyrant's Tomb, Shirley is among the unicorns that fight Tarquin's army during the Battle of San Francisco Bay.
Whagadoodle - A unicorn that lives in Camp Jupiter. In The Tyrant's Tomb, Whagadoodle is among the unicorns that fight Tarquin's army during the Battle of San Francisco Bay.
Venti – Storm spirits that were born when Poseidon opened a tunnel that sent Typhon into Tartarus. Depending on how chaotic they are, Venti can appear as either smoky men with angel-like wings or smoky horses. In The Lost Hero, Aeolus sent the Venti to prevent Jason, Piper, Leo, and the Hunters of Artemis from rescuing Hera. Their Greek counterparts are anemoi thuellai. In The Blood of Olympus, they attack the Argo II. Later, a team of ventus belonging to Notus is harnessed by Jason to tow the damaged ship to Malta.
Dylan – A ventus that was among the venti that attacked Jason Grace, Piper McLean, and Leo Valdez as seen in The Lost Hero. In The Blood of Olympus, Jason captures the biggest and meanest venti during the attack on the Argo II, unaware that its his old enemy Dylan. Dylan is forced to provide Jason air to breathe underwater, but unexpectedly aids Jason of his own free will in the battle against Polybotes, saving Jason's life. Through Kymopoleia, Dylan begs Jason to release him and promises never to attack Jason again. Jason is disgusted to realize that he has been "breathing Dylan", but Dylan earns his gratitude for Dylan's help against the Giant. Upon returning to the surface, Jason complies with Dylan's request and releases him.
Tempest – A ventus in smoky horse form that appears in The Lost Hero. Jason tames Tempest so that it can help him fight Porphyrion. After Jason dies in The Burning Maze, Tempest returns his body to his friends and then vanishes.
Carter Kane is one of two main protagonists and narrators; a descendant of Narmer and Ramses the Great. He is the son of Julius and Ruby Kane. After the death of his mother when he was eight, he spent six years travelling the world with his Egyptologist father. His sister Sadie lives with their maternal grandparents and Carter and his father visit Sadie twice a year, on the winter and summer solstices. After his father is captured by the god Set during The Red Pyramid, Carter spends most of his time with his sister Sadie and uncle Amos Kane. He becomes the host of Horus in the first novel, and often collaborates with and receives advice from the god. He also develops a romantic relationship with the shabti of magician Zia Rashid, and subsequently spends much of his time trying to find the real Zia and demonstrate his feelings toward her. Like his father, Carter has dark skin and hair, quite different from both his mother and sister. When living with his father, Carter dressed "impeccably" like Julius even when relaxing, but adopts a much more casual style when he goes to live at Brooklyn House. Though he is not one to flout rules, Carter is brave and courageous enough to pursue the way of the gods despite the House of Life's disapproval. His specialty is combat magic; his preferred weapon a khopesh, but loses it in The Throne of Fire.[22] He is often given leadership responsibilities and struggles to accept his role, until he willingly becomes pharaoh of the House of Life during The Serpent's Shadow. However, he decides to focus on leading Brooklyn House while leaving his uncle Amos as the Chief Lector to deal with the day-to-day running of the House of Life. In The Son of Sobek and The Crown of Ptolemy, Carter teams up with Percy Jackson and Annabeth Chase to combat Setne, briefly using Greek magic and Annabeth's invisibility cap.
Sadie Kane
Sadie Kane is one of two main protagonists and narrators; at thirteen years old, she is the younger sister of Carter Kane. She is left in the care of her non-magical grandparents in London after the death of their mother Ruby Kane. Though she is able to live a "normal" life, something her brother is occasionally jealous of, her unusual circumstances make her sometimes jealous of Carter. Sadie has to abruptly leave her life in London when she goes to revive the twenty-first Nome and fight Set after the god captures her father, Julius Kane. Sadie becomes the host of Isis in The Red Pyramid and continues to study the goddess's path throughout the series. She also becomes romantically involved with one of the Brooklyn House initiates Walt Stone and also with the god Anubis, though her relationship with either is not formalized until after Walt becomes the "eye" of Anubis in The Serpent's Shadow, due to this she is the only current polyamorous character in Rick Riordan's works.
She has caramel-colored hair, fair skin and blue eyes, some traits inherited from her mother Ruby. Unlike Carter, Sadie is rebellious and bold and acts the part; often making snap decisions, ignoring rules, and choosing to wear clothing to display her personality (such as combat boots) rather than to conform or aid her magic. Her magical specialty is with spells, potions, and hieroglyphics. One of her favorite spells is Ha-Di, which means to destroy.
Walt Stone
Walt Stone is one of the twenty-first Nome's initiates, who arrives at Brooklyn House sometime between the first and second novel. He has dark skin and is from Seattle, where he lived with his mother. Walt is a sau, or charmmaker.[22] In The Throne of Fire, it is revealed that Walt has inherited a deadly curse from his ancestor Akhenaten, which will kill him before reaches adulthood, as it did to his father and their famous ancestor King Tut. The curse progresses more quickly when he uses magic, which is why he specializes in charms and also why he begins to call on the god Anubis for guidance. In The Serpent's Shadow, Walt finally succumbs to the curse, but as he dies he allows himself to become the host of Anubis, whose spirit can essentially keep him alive. Both Anubis and Walt Stone have romantic feelings for Sadie Kane, which makes it easier for Walt to host Anubis. In The Staff of Serapis, Sadie tells Annabeth Chase that it's confusing dating both of them while they are merged, although she has accepted it.
Zia Rashid
Zia Rashid is a magician from the first Nome who was born and raised in Egypt. She is found and raised by Iskandar, the Chief Lector, after the destruction of her hometown by Apophis. When Julius Kane released five gods through the Rosetta Stone, she became the unexpected host of Nephthys, and was subsequently placed by Iskandar in an underwater prison so the House of Life could not eliminate her. A shabti of her was created to take her place; it is destroyed during the fight with Set in The Red Pyramid. Carter Kane falls in love with this shabti and seeks out the real Zia to free her and release Nephthys's spirit. Zia, who specializes in fire magic, later becomes the host of Ra and the two manage to destroy Apophis in The Serpent's Shadow. Her initial indifference to Carter slowly evolves into romance, and the two begin dating at the end of the series when Ra ascends back to the heavens.
Amos Kane
Amos Kane is Julius Kane's younger brother, Carter and Sadie's uncle, and the leader of the twenty-first Nome (New York). He takes in Carter and Sadie after Julius hosts Osiris and is trapped by the god Set. During the first novel, Amos is possessed by Set and forced to lure his niece and nephew to the god's pyramid in Phoenix, Arizona. Once freed, Amos goes for healing at the first Nome, and does not return to Brooklyn House until the second novel. His experience hosting Set has changed him, however, and eventually leads to his decision to voluntarily host the god during the final battle with Apophis. Amos succeeds Michel Desjardins as leader of the House of Life after he sacrifices himself fighting Apophis. After the final battle, Carter becomes the Pharaoh, but leaves Amos in charge of running the day-to-day operations of the House of Life in Amos' capacity as Chief Lector.
Anubis
Anubis is the God of funerals and death with the appearance and personality of a teenager despite him being over 5,000 years old. Anubis is the son of Nephthys and Set, but felt closest to his uncle Osiris, who raised him in Duat. Unlike the other Egyptian gods, Anubis does not require a host to manifest on Earth and is instead able to appear in any place of death. In The Red Pyramid, Sadie sees him several times in dreams without understanding who he actually is and develops an immediate attraction to Anubis. To get the Feather of Truth, Carter and Sadie travel into the Underworld where Sadie meets Anubis in person for the first time and convinces him to give her the feather before Anubis teleports them to New Orleans. Later, Anubis appears to Sadie when she touches her father/Osiris' tomb and attempts to warn her against her actions. Days after the battle is over, Anubis visits Brooklyn House to transport Carter and Sadie to meet with their father and Osiris, calling his time with Sadie "stimulating", but annoying Sadie as Anubis tells her mother that Sadie has a sharp tongue.
In The Throne of Fire, Anubis appears in a graveyard in London while she is being chased by two hostile gods, although he is unable to help her directly as Anubis can't manifest outside of the graveyard. Instead, Anubis directs Sadie to the second part of the Book of Ra and gives her a Netjeri blade and kisses Sadie as a birthday present. After Sadie and Carter are knocked unconscious, she encounters Anubis in a dream who is talking with Walt Stone and he gives her more advice about the Book of Ra. To Sadie's disappointment, Anubis is not present when she and Carter are gambling their souls with Khonsu. Anubis later states that he was busy with a "side project" that he won't elaborate on while Walt glances at a picture Sadie made of Anubis, suggesting that the god and the magician are plotting something together.
In The Serpent's Shadow, Anubis appears with Sadie's mother after she is knocked unconscious and offers her clues about the shadow box that she saved. During a dance that Sadie attends, Anubis appears to dance with her, stunning the popular girls who were harassing Sadie moments before, including Greek demigod Drew Tanaka and making them extremely jealous. Anubis offers Sadie advice on her and Carter's plan to destroy Apophis despite the magic being so forbidden that he's not even allowed to talk about it. Anubis then reveals that ghosts are being absorbed by Apophis' shadow before his great-grandfather Shu appears to break the two up. Shu reveals that due to Anubis' growing romantic feelings for Sadie, he has been banned from seeing her with Anubis stating that such a relationship is forbidden unless the god is using a human host which has never been how Anubis works.
Walt eventually admits to Carter that Anubis thinks he only has until the next day's sunset to live and that the god has been helping him to make sense of his strange new power to turn things to dust. Anubis thinks he understands why Walt has that particular power and Anubis has a plan to extend his life, but it's not a cure and is risky, never been done before and might come with side effects that they won't like. When Walt is near death from his curse, Anubis appears to him and Sadie is annoyed to realize that the two have been plotting behind her back together. Near death, Walt agrees to what they've been planning together, both Anubis and Walt unable to bring themselves to leave Sadie. After Walt dies, Anubis vanishes and Walt is suddenly resurrected. Sadie finally realizes that Walt and Anubis' plan was for Walt to become Anubis' host and that Walt's strange death powers had come from him channeling Anubis' power for months. Overwhelmed, Sadie leaves through a portal that Anubis opens for her to help Carter while Walt and Anubis, still too weak to move, remain behind for the time being to recover.
Anubis and Walt fight in the final battle with Apophis and the rebel magicians, playing a crucial role in the defeat of the latter. Although Apophis' destruction means that the Egyptian gods must depart the Earth for the time being, Anubis using Walt as his permanent host means that he can stay and pursue a real life, something that Anubis has never gotten before. Sadie starts a romantic relationship with Walt and Anubis, finally able to be with both of the boys that she loves without having to choose between them.
In The Staff of Serapis, Sadie mentions to Annabeth Chase that she's still dating both Walt and Anubis and that it's confusing, but she has accepted it. Annabeth is left confused by the comment about Sadie's "funeral god boyfriend", but she doesn't question it.
Iskandar
Iskandar is the Chief Lector of the House of Life. Born in the 1st century BCE, during the reign of Cleopatra VII, he witnessed the end of the Egyptian monarchy and the absorption of Egypt into the Roman Empire. He came to believe this was the fault of the gods and ended the House's policy of calling upon them; Ruby Kane's vision of Apophis rising changes his mind, but it is too late for him to make any real change. He saved Zia after her village's destruction and, sensing that she holds the power to host Ra, arranged for her confinement in an underwater prison under the watch of Nephthys while creating a shabti of her to protect Carter and Sadie, both of whom also hold the potential to become hosts of gods. Shortly after meeting them, he dies in his sleep, knowing that these three can make a change where he could not. He is succeeded by Michel Desjardins as the House's leader. Sadie briefly encounters his spirit in the Realm of the Dead while making her way through it.
Michel Desjardins
Michel Desjardins is the lesser antagonist and leader of the House of Life after the death of Iskandar. Desjardins is the grandnephew of Jean-François Champollion and approximately 200 years old, considered "young" for a magician. As such, he has known only the House policy forbidding the Path of the Gods. He is therefore at first opposed to cooperation with the gods and disagrees with the Kanes when they claim it is necessary to stop Apophis. As a result of his antagonistic behavior, the Kanes wrongly suspect him of being the host of Set in The Red Pyramid. After Set's defeat, Desjardins is outraged that Carter and Sadie chose to make a deal with the god rather than banish, but chooses not to attack them in the end, realizing that enough fighting has been done for one day and that his men appear to be wavering after witnessing the Kanes give up the powers of Horus and Isis willingly. In The Throne of Fire, he works with Vladimir Menshikov in the latter's attempt to hunt Sadie and Carter Kane, believing his lies about how the Kanes' efforts will empower Apophis. Throughout the book, Desjardins grows visibly weaker and older and Zia Rashid realizes that Menshikov has been poisoning him while Desjardins mistakenly believes that it is the weight of leadership getting to him. Desjardins eventually realizes the truth and comes to the Kanes rescue in the Duat where Menshikov has been possessed by the spirit of Apophis. Desjardins casts an execration spell upon Menshikov, killing him and banishing Apophis deeper into the Duat for a while. However, the effort costs Desjardins his life as Desjardins uses up all of his life force to cast the spell. Before dying, Desjardins makes peace with the Kanes and has them pass on his title of Chief Lector of the House of Life to Amos Kane. He is mentioned several times throughout The Serpent's Shadow, particularly in relation to how the Kanes plan to defeat Apophis is to perform their own execration upon the god. It's noted that Desjardins only faced a weaker manifestation of the snake and couldn't do more than banish him for a while the Kanes face Apophis himself at his full power.
Set
Set is the ancient Egyptian god of evil and the secondary antagonist of The Red Pyramid and a supporting character in The Throne of Fire and The Serpent's Shadow. Although he initially appears to be the main antagonist of The Red Pyramid, Set is actually manipulated secretly by Apophis throughout the book. While Set is evil, he is stated many times to be more of a necessary evil, unlike Apophis. In ancient times, Set acted as the faithful lieutenant of Ra in the eternal war against Apophis and he was born on the third Demon Day, or December 29. He would eventually marry his sister Nepthys and have a son with her, Anubis, but Anubis was raised by Osiris and Isis instead. After Ra retreated into the heavens and Osiris became the new Pharaoh of the gods, Set refused to stand for it, imprisoned his brother in a magnificent sarcophagus and relentlessly chased Isis who was able to rescue Osiris. However, Set blew Osiris into fourteen different pieces and although Isis managed to reconstruct her husband, she was only ever able to resurrect him as the Lord of the Underworld. Set was eventually dethroned by Horus in revenge and in time, would be imprisoned along with the rest of the gods by the House of Life.
In The Red Pyramid, Julius Kane uses the Rosetta Stone to release Osiris and return him to his throne in the Underworld as a first step towards restoring the gods due to the increasing threat of Apophis. However, Julius inadvertently releases all five gods of the Demon Days, including Set who imprisons Julius and Osiris in a sarcophagus and begins draining them of their power. He also secretly possesses Amos Kane to get close to Julius' children Carter and Sadie, the hosts of Horus and Isis respectively, whom he sends various minions after, including two other gods. Goaded by his demon minion Face of Horror, Set decides to summon a storm that will destroy North America at sunrise on his birthday to increase his own power. Despite Set's machinations and having to avoid the House of Life, the Kanes manage to confront Set at his base, the Red Pyramid. As Carter fights Set, Sadie teleports the pyramid to Washington, DC through a portal, severing Set from the source of his power, the desert, and stopping the storm and his plot. Having gotten Set's secret name "Evil Day" from Nepthys, Sadie performs a spell to banish Set deep into the Duat, but sensing that something is wrong, looks into the rift that the spell opened and spots Apophis, the true orchestrator of the plot. Breaking the spell, Sadie uses the Feather of Truth to show Carter and Set Apophis in the sky and Carter kills Face of Horror who is revealed to be possessed by Apophis whose true plan was to use the Chaos energy generated by Set's storm to escape from his prison. Rather than continue their attempt to banish Set, the Kanes negotiate with him, recognizing Set as a necessary evil and an important part in the war with Apophis. In exchange for being released, Set swears on his secret name and Ra's throne to not return until he is summoned to help in the fight against Apophis. Once Set is released, he departs into the Duat.
In The Throne of Fire, Vladimir Menshikov summons Set into a malachite jar, trapping him and using his knowledge of Set's secret name to force the god to reveal the properties of Apophis' prison. Noticing the Kanes hiding nearby, he alerts Menshikov to their prison and, outmatched by the older magician, Sadie breaks the jar and frees Set who incapacitates Menshikov and allows the Kanes to escape as thanks. After Carter is poisoned by a deadly monster snake, Set helps Sadie get Carter to safety and in exchange for Sadie giving him back his secret name, he offers her the location of the last part of the Book of Ra which Bes confirms that Set would know as he was the one to hide it. After making Set agree to a continuing truce with her family, Sadie takes the deal. In addition, Set informs Sadie of where to find the missing Zia Rashid, which makes Sadie suspicious as Apophis did the exact same thing, although not as well as Set. To Sadie's surprise, Set keeps their deal and departs without trying to harm them. He is later present when Ra retakes his throne.
In The Serpent's Shadow, Amos is revealed to have been communicating with and channeling the power of Set, concerning Carter, Sadie and Zia who fear that Set may be controlling Amos again. Set appears to Carter on the Egyptian Queen and reassures Carter that he is not manipulating Amos, implying that Amos had in fact sent Set to talk to Carter. Set insists that he is simply a necessary evil, balancing out the other gods who are good and that he does not want Apophis to win, reminding Carter of his service as Ra's faithful lieutenant. During the final battle with Apophis and the rebel magicians, Amos acts as Set's host and although Amos is in control, he appears to struggle with some of Set's more violent tendencies. After Apophis is destroyed, Set is exiled along with the other gods. He attends Horus' coronation as Pharaoh of the gods, supporting him, but with a smile that suggests that Set has something evil planned. In addition, Amos begins wearing crimson clothing which Carter thinks is to play up his connection to Set. As a result, Carter doubts that Amos will have any more trouble enforcing his rule.
Apophis
Apophis is the serpent of Chaos who fought Ra in ancient times and the primary antagonist of The Kane Chronicles. When Ra eventually retired to the heavens, he sacrificed his third aspect Khepri to seal Apophis away in a prison deep within the Duat and sent his loyal cat goddess Bast to fight Apophis for eternity inside of the prison. Before the series begins, Ruby Kane, who has prophetic abilities, foresees Apophis' eventual escape and sacrifices herself to rescue Bast from their prison as a first step to restoring the gods and preventing Apophis' rise.
In The Red Pyramid, Apophis acts from behind the scenes after Julius Kane begins the process of releasing the other gods. By possessing Set's demon minion Face of Horror with a fragment of his soul from within his weakened prison, Apophis pushes Set to create a storm that will destroy all of North America which will create enough Chaos energy to allow Apophis to break free. Both the gods and the magicians remain unaware of Apophis' role in the events, believing that Set is only acting on his own, something that Set himself is also unaware of. During the final battle, as Sadie Kane performs a banishing spell for Set, the advice of her mother causes her to look into the sky and see Apophis within the rift opened by the spell and she finally understands the truth. Breaking the spell, Sadie uses the Feather of Truth to reveal Apophis to both her brother Carter and Set. Enraged, Apophis has Face of Horror attack Sadie, but Carter kills him with his sword. As the demon dies, Apophis taunts them at what he had managed to accomplish through only a fragment of himself before the fragment rejoins Apophis in the closing rift. Recognizing that Apophis is returning and is the greater threat, the Kanes make a deal with Set rather than banishing him.
In The Throne of Fire, the Kanes and their allies work to combat Apophis' inevitable escape by locating and restoring Ra to power. At the same time, Apophis has magician assassin Vladimir Menshikov, one of his allies, hunt the Kanes and sends various monsters after them. Despite the best efforts of Apophis' forces, the Kanes manage to awaken Ra, but he is in a weakened and senile state. In a final confrontation in the cavern holding Apophis' prison, the Kanes learn that the price of retrieving Khepri - Ra's final aspect - is the release of Apophis from his prison. Sadie nevertheless completes the spell, taking the final beetle of Khepri's form and releasing Apophis who possesses Menshikov to fight the Kanes directly, proving to be more than a match for them. However, House of Life Chief Lector Michel Desjardins arrives to help after finally believing that the Kanes are telling the truth. Desjardins performs an execration spell on Apophis, a spell that uses a small representation of a target to completely erase the spell's target. However, as a god, Apophis can't be killed by the spell which only destroys Menshikov and banishes the serpent a little deeper into the Duat, buying the Kanes time to escape with Ra. Desjardins dies after using up all of his life force to banish Apophis.
In The Serpent's Shadow, Apophis is in an all-out war with the House of Life and has secretly allied himself with the rebel magicians who are fighting against Amos Kane's leadership of the House of Life, putting the Kanes and their allies into a two-front war that they are slowly losing. The Kanes learn that Apophis intends to rise on the fall equinox while having the rebels attack the First Nome at the same time. With Ra still in a senile state, the Kanes desperately search for a way to defeat Apophis and learn that he has been destroying copies of the Book of Overcoming Apophis written by Setne and attempt to secure the last copy resulting in a battle that destroys the Fifty-First Nome and kills many of their remaining allies. Sadie manages to banish Apophis from the battle by invoking Ma'at, but the effort involved nearly kills her. However, the magicians manage to recover a shadow box containing King Tut's sheut or shadow which is a part of his soul. Carter comes upon the idea of using Apophis' own shadow in a stronger execration spell which Anubis reveals is possible, but is highly secret and forbidden magic as such a spell could destroy even a god forever. With the help of Setne, Carter and Zia Rashid seek out Apophis' shadow which has been absorbing the souls of many people, including their mother, to help boost the serpent's power. The two manage to capture the shadow and escape with the unexpected help of elderly gods from the Duat.
Upon emerging in the mortal world, it's discovered that Apophis has begun his attack which is only held off only by Bast. While the Kanes rush to help their friends, Ra, reborn after taking Zia as a host, Sobek and Bes join the fight to hold him off. After defeating the rebel magicians, Carter calls upon the gods to join the battle, but even together they prove to be no match for Apophis who kills Nekhbet and swallows Ra, darkening the sun. With all hope seemingly lost, Carter and Sadie, with the help of Horus and Isis, cast the shadow execration upon Apophis while Bast and Bes hold Apophis off to buy them the time that they need. As he casts the spell, Carter comes to the understanding that Apophis' shadow is more than just a "backup copy" of a person's soul, it stands for their legacy, their impact on the world. With no shadow, a person's existence becomes meaningless and they can't be alive. As a result, even if Apophis manages to survive the spell, it will cut his connection to the mortal world and he will never be able to rise again. Apophis defeats Bes and Bast, but is too late to stop the Kanes from finishing the spell, destroying his shadow. All of the souls that the shadow had consumed are released and it shatters his legacy upon the world, causing all of the wars, murders, turmoil and anarchy Apophis has caused since ancient times to lose their power and finally stop casting their shadow across the world's future. As he dies, Apophis warns the Kanes that they haven't just killed him, but they have exiled the gods as well because Ma'at and Chaos are linked and to push one away is to push the other away. As Apophis tells the Kanes that Ra will die within him, Ra suddenly explodes out of Apophis, blowing Apophis' head apart. Apophis is destroyed and crumbles into sand and steaming goo.
Setne
Setne is an evil magician and the son of Ramses the Great. His real name is Prince Khaemwaset, but he hates it. He is a secondary antagonist in The Serpent's Shadow and the primary antagonist of the Demigods & Magicians crossover series. He is mentioned to have performed a number of evil deeds for which he has always managed to get away with. These are stated to include causing the French Revolution and triggering World War I. He is also known to have traveled and explored extensively and to have stolen a number of spell books that he should never have gotten his hands on and to have created a number of his own spells. His ultimate ambition is to become a god himself and his power is only constrained by the fact that he is long dead and is currently a ghost.
In The Serpent's Shadow, the Kanes and their allies seek out the last copy of the Book of Overcoming Apophis written by Setne, having come to the conclusion that it holds the secret to defeating the evil god since he has specifically targeted all of the existing copies. Setne himself appears to Sadie Kane, warning her that she will need his help and to save a shadow box. The book is destroyed, but the shadow box presents a clue that causes the Kanes to realize that Setne may have developed a way to kill an immortal being using their shadows or sheuts. With Setne facing oblivion in the Underworld, the Kanes convince their father Julius and Osiris to lend Setne to them and he leads Carter and Zia to the Book of Thoth and then into the Land of Demons to get Apophis' shadow. After several foiled betrayals, Setne manages to subdue Carter and Zia and reveals that he intends to force Apophis to obey his commands, having needed their help only to get the shadow. The timely arrival of Sadie foils Setne's plan, but he somehow manages to escape with the Book of Thoth and the dangerous magic within. The magic that Setne taught the Kanes enables them to destroy Apophis forever and restore Bes, but they are left concerned by the implications of his escape. Julius states that Setne was bound to get away again and that the best they could've hoped for was that he would help them long enough to get the shadow and the spell.
In Demigods & Magicians, Setne begins using hybrid Greek-Egyptian magic from the Book of Thoth, repeatedly drawing the attention of the Kanes, Percy Jackson and Annabeth Chase to stop him. In The Crown of Ptolemy, Setne enacts his ultimate plan by stealing the crown of Egypt and the power of the goddesses Wadjet and Nekhbet to finally become a god himself. Unable to defeat Setne with their individual powers, the Kanes, Percy and Annabeth share their powers with each other so that the demigods are using magician abilities and the magicians are using demigod abilities which proves to be highly effective against Setne, allowing them to retrieve the Book of Thoth. In a final effort, the Kanes and Annabeth perform a spell from the Book of Thoth to imprison Setne while Percy becomes the host of Nekhbet to fight Setne directly. Ultimately, after falling into the ocean, Percy's natural power from Poseidon combined with his borrowed power from Nekhbet allows him to overpower Setne and strip him of all of his stolen power. However, Percy chooses not to destroy Setne as he is not the kind of person to do that despite Nekhbet pushing him to do it. The completed spell then traps Setne forever inside of a snow globe which becomes a paperweight on Carter's desk.
In the Brooklyn House Magician's Manual, Setne is shown plotting to escape after his prison is accidentally cracked by one of Sadie's spells after which he intends to take the Book of Thoth, travel into the Duat and finally become a god. However, his eventual escape is actually anticipated by the Kanes and engineered so that it doesn't happen when no one's watching which would be bad for everyone. Although Setne causes some minor chaos, he is tracked by Walt and Anubis who, due to Anubis' powers over death, are able to track him even while he's invisible. Setne is ultimately trapped in a mastaba and bound by multiple containment spells to contain him until he faces judgment in the Underworld.
Egyptian deities
Babi — A baboon god who takes Mr. Faust as host, helping Nekhbet test Sadie Kane. He later participates in the final battle with Apophis.
Bast – Cat goddess and Ra's guardian. In ancient times, she was sent by Ra to fight Apophis after the latter ascended to the heavens, which she continues to do until Julius and Ruby Kane release her. She then takes as host a cat named "Muffin" and makes a pact to guard Sadie. Bast then becomes Carter and Sadie's guardian after the two become magicians, and becomes quite close to them. In The Red Pyramid, she sacrifices herself fighting Sobek to protect Sadie, but is brought back from Duat by the gods as reward for the Kanes after they defeat Set. Alongside Bes, she continues to act as their friend, mentor and protector. In The Tower of Nero, she is mentioned to have been meeting with Chiron and Mimir about an unidentified threat to all of the pantheons.
Bes — God of dwarfs and protector of the innocent. He has romantic feelings for Bast, and answers her request that he watch over Carter and Sadie. He befriends the two and sacrifices his ren to give them enough time to reach Apophis's prison. The two later manage to restore him, and he goes on to pursue a relationship with the goddess Tawaret.
Geb — God of the earth. Father of Osiris, Isis, Horus, Set, and Nephthys; husband of Nut. His physical manifestation is the entire earth.
Hapi — God of the Nile river. In The Serpent's Shadow, he is summoned by Carter using a spell from Setne, and asked to defeat a monster sent by Apophis. Hapi also helps Carter and Zia cross the Nile to reach the temple of the Apis Bull. Hapi is described as huge, blue-skinned, and well-fed.
Heket — A frog goddess who lost her power when her temples were destroyed and people stopped worshiping her. She is currently living in Sunny Acres Assisted-Living Community, a place for senile gods and goddesses.
Horus — God of war, who led the gods until Ra's return, and again after Apophis is destroyed. Part of his spirit resides in Carter Kane. His symbol is the Eye of Horus. He is one of the five gods born during the Demon Days, the son of Geb and Nut. He is also frequently described as the son of Osiris and Isis.
Isis — Goddess of magic, briefly incarnated by Sadie Kane. She is one of the five children of Geb and Nut, and mother of Horus. She is responsible for Ra's ascendance from the mortal world. When she wanted her husband Osiris to claim Ra's throne, she created a serpent to poison Ra. When he revealed to her his secret name, she cured him but also forced him to abdicate the throne.
Khonsu — Moon god. He was a trickster who liked to play senet, a board game, with deadly bet in return for a lengthened time; Nut once played a game with him so she could gain enough time to give birth to her five children. In The Throne of Fire, the Kanes and Bes played senet with him so they could gain more time for the gates of Duat to open; when they lose a round, Bes sacrificed his ren, which caused him to lose his memories until the Kanes managed to find his sheut in The Serpent's Shadow.
Mekhit and Onuris — Two war gods who were forgotten by humans and thus had to live in Sunny Acres. Onuris disappeared due to his senility, which made Mekhit mournful. He is found again in The Serpent's Shadow, and later fights alongside his wife with the retired gods who helped the Kanes.
Neith – Goddess of hunting. She briefly appears in The Serpent's Shadow when Sadie and Walt trick her into helping them, and later fights alongside them against Apophis.
Nekhbet — Vulture goddess who takes Mrs. Faust and Percy Jackson as hosts. She is a follower of Ra, but refuses to follow the weak. As a result, she "tests" Sadie Kane's strength by attempting to kill her, her family, and her friends. It is revealed in The Crown of Ptolemy that Nekhbet possesses the crown of Upper Egypt, which Setne steals, although she manages to avoid Wadjet's fate of having her essence absorbed thanks to the Heroes. She proceeds to assist them to recover her crown, taking Percy Jackson as a host and lending him her powers.
Nephthys — Goddess of rivers, wife of Set, mother of Anubis, and one of the five children of Geb and Nut. She was once incarnated by Zia.
Nut — Sky goddess, mother of Osiris, Isis, Horus, Set, and Nephthys. Wife of Geb. Due to a prophecy that one of her children would unseat him, Ra forbade Nut to give birth on any day of the year. She gambled with the god Khonsu to earn five extra days worth of moonlight to have her children and was punished by Ra. He forbade her to ever see her husband again, and tasked her father Shu with keeping them apart. Her physical manifestation is the sky itself.
Osiris — The god of the dead, incarnated in The Red Pyramid by Julius Kane. He is one of Geb and Nut's five children. His symbol is the 'Spine of Osiris', or the djed. He is frequently described as having blue skin, representing the fact that he is "dead". He was once king of the gods until his brother Set imprisoned and later killed him. His wife Isis and sister Nepthys searched for his body to revive him with magic, but were only able to make him pharaoh of the Duat.
Ptah — God of craftsmen and creation, summoned by Sadie and Walt to help them get a piece of the Book of Ra.
Ra — Sun god. Retired to the heavens, but revived in The Throne of Fire; later merges with Zia and recovers his lost mental integrity. Consumed by Apophis and later revived by Sadie and Carter. He was the first and greatest king of the gods, and undertook nightly journeys through the Duat to battle the forces of chaos. After the destruction of Apophis, he retires to the heavens once again and takes the other gods with him aside from Anubis.
Khnum — Ra's evening aspect who created man out of clay using a potter's wheel. In The Throne of Fire, the Kanes meet him near the entrance of the Duat and have one chance to guess his name, which he had forgotten after so long. Sadie eventually gave him his ren, and he allows them to pass on to revive his other aspects.
Khepri — Ra's morning aspect that had the form of a golden beetle. The Kanes found it near the exit of Duat and had to battle Valdimir Menshikov, possessed by Apophis, to give it to Ra and thereby restore his final aspect. Ra later gives Khepri to Zia Rashid who is able to channel his powers. Khepri also protects Zia and Carter Kane from the power of Chaos in the Land of Demons.
Sekhmet — Goddess of lions. She can be summoned by a Chief Lector once in his/her lifetime, and attacks Carter, Sadie, Zia, and Amos at the command of Michel Desjardins. She is the lieutenant of Ra and a master of destruction.
Hathor — Goddess of cows, and alter-ego of Sekhmet. She is summoned whenever Sekhmet is tired, and represents her peaceful side.
Serqet — Goddess of scorpions. In The Red Pyramid, she attacked Carter, Sadie, and Bast after the three had escaped from Brooklyn House, forcing Bast to retreat while the Kanes were saved by Zia. She reappears in The Serpent's Shadow where she helps to battle Apophis.
Shezmu — God of execution. In The Red Pyramid, he prevented the Kanes from entering Duat unless they told him his secret name, although he ended up revealing it to Sadie while the three compromised.
Shu — God of the air, and father of Nut and Geb, who separates Nut from Geb to form the present-day division of Sky from Earth. Later appears to criticize Anubis' infatuation with Sadie although he helps at the same time by teleporting a young Russian magician to Brooklyn after being summoned by the young man. After Anubis becomes hosted by Walt Stone, he tells Sadie that Shu will no longer intervene, but will likely keep an eye on them notheless.
Sobek — God of crocodiles, who appears as a minor antagonist in The Red Pyramid serving Set. Bast is forced to sacrifice herself to defeat him. Sobek returns in The Serpent's Shadow guarding Ra on his nightly journey. It's stated that Sobek apparently only agreed to join their side because Horus and Isis had threatened him with extreme bodily harm otherwise. He joins Ra and Bast in holding Apophis off. In The Son of Sobek, Carter and Percy Jackson face off against the petsuchos, Sobek's sacred animal which is also known as the Son of Sobek. Sobek is mentioned a few times in relation to the monster and Carter's previous encounters with the god.
Taweret — Goddess of hippos and childbirth, assists the protagonists. As a protector of the innocent (specifically children), like the god Bes, she is very familiar with him and has romantic feelings for him. At first these are unreciprocated as he is in love with Bast, but he comes to appreciate and care for her after she takes care of him when he has lost his ren. Tawaret is the sole nurse in the Sunny Acres retirement community for old gods, located in the Duat.
Thoth — God of knowledge and founder of the House of Life. "Thoth" was actually his Greek name; the Egyptians called him Djehuti. He is the only god who is accepted by the House of Life and is allowed to inhabit the mortal world; he is found in Memphis in various locations. Carter and Sadie seek him out for advice on two separate occasions.
Wadjet – A cobra goddess who makes a brief appearance in The Crown of Ptolemy where Setne summons her, steals her crown of Lower Egypt, and then steals her essence, killing her. She is freed after the Kanes, Percy Jackson and Annabeth Chase defeat Setne.
Magicians
Brooklyn House trainees
Jasmine 'Jaz' Anderson — One of the novitiate magicians in Brooklyn House. She is a blonde, sixteen-year-old cheerleader from Nashville, Tennessee. Her specialty is healing magic and studies the goddess Sekhmet as all Egyptian healers do. She is put into a coma after banishing some sickness demons in The Throne of Fire, from which she is awakened by Ra. She shares with Sadie how to cure Carter using his ren when he is bitten by a tjesu heru.[23] She later appears in The Serpent's Shadow and her healing potions appear in the crossover stories The Son of Sobek and The Staff of Serapis.
Alyssa – A trainee of the twenty-first Nome with a particular skill for pottery and shabti-making. She studies the power of Geb.
Cleo – One of the young magicians at Brooklyn House. She is from Rio de Janeiro. She speaks Portuguese (as being her mother-language) and she often switches back to Portuguese when she’s anxious. Cleo studies the god Thoth and will likely be Brooklyn House's next librarian. Though she is an excellent researcher, she does not have much of a stomach for violence.
Felix – A 10-year-old trainee at Brooklyn House. He has a strange obsession with penguins and seems to be able to channel ice magic, although it is unknown which Egyptian god this corresponds to. In The Tower of Nero, Rachel Elizabeth Dare mentions seeing Brooklyn House and some of Felix's penguins, something that greatly confuses her.
Julian — A seventh-grade trainee. Like Carter, he incarnates the power of Horus.
Sean – An Irish trainee at Brooklyn House.
Shelby – A young trainee at Brooklyn House, the ringleader of the group of toddler trainees known as the "anklebiters". Her magic is mostly impulsive.
Tucker - A 10-year-old trainee at Brooklyn House.
Leonid – A young Russian magician who first encountered the Kanes when they visited Saint Petersburg. He defects to the "side" of the gods and, with the help of the god Shu, brings Sadie and Carter information during The Serpent's Shadow.
Other magicians
Julius Kane — Carter and Sadie's father, and a doctor of Egyptology. After a failed attempt to release the Egyptian goddess Bast back into the world kills his wife, he works to find a way to release them again and becomes host to Osiris. He ultimately succeeds, dies of his own free will, and goes to "live" as the god's physical manifestation in the Underworld, overseeing the Hall of Judgment.
Ruby Kane — Carter and Sadie's late mother, who appears occasionally as a spirit to advise her children. She was a magician and diviner who foresaw Apophis's rise and ultimate victory if the other gods were not there to stop him. As a result, she and her husband attempted to release Bast from her eternal battle with Apophis so the goddess could heal before his inevitable rise. She gave her life to close the portal they opened using Cleopatra's Needle, because Apophis was fighting to get out. Ruby also communed with Isis at some point in her career as a magician, and attempted to convince then-Chief Lector Iskandar to remand his policy of fighting the gods.
Vladimir Menshikov — The antagonist of The Throne of Fire. Menshikov's intense hatred of the gods and desire for power leads to his possession by Apophis. He manipulates Michel Desjardins into permitting him to hunt the Kane family. When Desjardins finally discovers his involvement, he uses up all his energy in an execration of the chaos demon and, by extension, Menshikov, who is then killed. Menshikov is described by Sadie and Carter Kane as an "evil ice cream man"[22] because of his tendency to wear white suits and glasses because of his heavily scarred face.
Sarah Jacobi – The leader of a group of rebel magicians, a former House scribe imprisoned for causing the 2004 Indian Ocean earthquake and tsunami. In The Serpent's Shadow, she manages to amass an alliance of rebels in league with Apophis, but is vanquished by Anubis/Walt Stone, who summon spirits to pull her into the Underworld.
Kwai – Sarah Jacobi's assistant, the House of Life's persistent opponent throughout the later books and also a brief host of Apophis. After being defeated by Walt Stone/Anubis, he uses the last of his life force in an effort to bring down the Hall of Ages upon the combatants, killing Kwai in the process. However, Sadie succeeds in foiling his plan.
Egyptian creatures
Ammit the Devourer — A part-hippo, part-crocodile, part-lion demon who devoured souls that were judged unworthy in the Halls of Judgment. The Kane Chronicles present a different picture of Ammit than is typical, by portraying the demon as both no larger than a toy poodle and as a male.
Bau - Evil Egyptian plague spirits.
The Seven Arrows of Sekhmet - Seven powerful plague spirits created by Sekhmet. They are set up in the Brooklyn Museum by the forces of Apophis as a trap for the Kanes and their allies and are released when Sadie grabs the first part of the Book of Ra, activating every reservoir of magic in the museum. One is destroyed by Freak the griffin who eats the bau with no ill effects, but another infects Walt Stone. Healer Jasmine "Jaz" Anderson manages to cure Walt, but at a great cost to herself. With the remaining bau infecting the innocent mortals present in the museum, Jaz manages to channel the power of Sekhmet to banish the six surviving bau back to the Duat, curing their victims while the magicians escape on Freak. However, the amount of energy that Jaz had expended in the process sends her into a coma that she doesn't recover from until the return of Ra to the world revitalizes her.
Carriers — Copper-skinned men who capture targets, put them into a black box known as a sedan and take them to their masters. In The Red Pyramid, four carriers chase after the Kanes and Bast as they attempt to escape to a location where they can open a portal to escape. Bast sets the cats of New York City onto the carriers, but it only distracts them briefly with the carriers continuing their chase at superhuman speed. As Sadie struggles to open a portal, Bast battles the carriers in her combat avatar, but they reform each time that she destroys one of them. Finally, Carter joins in and he is ordered by Bast to slice them up into smaller pieces. After Bast destroys each one, Carter slices them up into tinnier pieces with his khopesh, finally destroying them once the carriers have been turned into tiny pieces of clay. However, the victory doesn't last long as the goddess Serqet arrives shortly thereafter to continue the fight with her army of scorpions.
Criosphinx — A type of ram-headed sphinx encountered by the Kanes while they were in Luxor, Egypt. Dozens of them were summoned by House of Life magicians to kill the Kanes, but Carter managed to destroy one while Sadie opens a portal to Paris and escape. Carter suffers at least one broken rib and loses his sword, but he also manages to escape through the portal, inadvertently pulling two of the criosphinxes along with him. However, Bast appears to help and quickly destroys both of the creatures.
Egyptian Demons — The minions of Chaos who serve a variety of masters, in particular Apophis and Set. Their homeland is the Land of Demons which is located deep within the Duat.
Bloodstained Blade — A demon who is bound to serve the Kane family, which he deeply resents and who acts the captain of the Egyptian Queen. In The Red Pyramid, Bloodstained Blade takes the Kanes into the Duat to meet with Anubis. He is disappointed when the Kanes refuse to release him from their service. In The Serpent's Shadow, Carter summons the Egyptian Queen to carry himself, Zia Rashid and Setne on their quest to get the Book of Thoth and Apophis' shadow. However, Carter makes the mistake of giving Setne permission to give orders to Bloodstained Blade and he orders the demon to take them to the Land of Demons and to kill Carter, an order that he happily complies with. After a battle, Bloodstained Blade is incinerated by Zia while Setne claims that he knew that Carter could take the demon and that giving him the order to kill Carter is the only way that Bloodstained Blade would have taken them to the Land of Demons.
Death-to-Corks - A corkscrew-headed demon that had served Vladimir Menshikov for over fifty years. In The Throne of Fire, Carter and Sadie witness Menshikov dispassionately destroy Death-to-Corks with an execration, a powerful spell that uses a smaller representation of a target - in this case an ordinary corkscrew - to utterly erase a being from existence. Menshikov then uses the power generated by Death-to-Corks' destruction to summon Set.
Face of Horror — Set's demon lieutenant in The Red Pyramid who pushes him to create a cataclysmic storm that will destroy North America, ostensibly to increase Set's own power. During the final battle, its revealed that Face of Horror actually serves Apophis who is possessing the demon with a fragment of his soul. Enraged over the defeat of his plan, the Apophis-possessed demon attacks Sadie Kane, but Carter is able to kill him by throwing his khopesh into Face of Horror's side. Before the demon dies, Apophis taunts the Kanes about how much he accomplished just through his possessed minion. In The Serpent's Shadow, Face of Horror has been resurrected by Apophis and granted wings. He leads the attack on Thoth's home and, once again possessed by Apophis, taunts Carter. However, Face of Horror is quickly killed for a second time by Thoth.
Egyptian Griffin - The sacred animals of Horus. Unlike the Greek Gryphons, the Egyptian Griffins have reddish-gold fur, are twice the size of lions, and have hard tails that are strong enough to break stones.
Freak – Carter's pet griffin, who greatly enjoys eating turkeys, both frozen and cooked. In The Throne of Fire, he is a statue in the Brooklyn Museum and he is inadvertently brought to life when Sadie activates one of Apophis' traps. Due to his connection to Horus, Carter discovers that he can command the griffin as the creature is one of the god's sacred animals. Carter manages to use this to tame Freak and the magicians escape on his back. Freak subsequently chooses to remain at Brooklyn House as Carter's pet rather than taking off on his own and he is often used by Carter and the magicians as their primary method of transportation via a boat tied to Freak's back, particularly in The Serpent's Shadow when portals are unreliable. Young magician Felix loves yelling "ho, ho, ho" as he rides Freak, leaving it unknown what mortals think as they can't actually see the griffin while Carter is very fond of Freak, building him his own roost on the mansion's roof and often visiting Freak. Freak occasionally aids in battles and in one case, clean up by attaching dusting cloths to his wings and flying around with them. When Carter takes Zia on their first date to the Mall of America, he picks her up in Freak and parks the griffin on the mall's roof with a pile of frozen turkeys.
Khufu — Amos's pet baboon. Like many baboons in the series, he loves basketball and speaks only in monosyllabic grunts. Khufu's other quirk is that he only eats things that end in the letter 'O', such as Cheerios, Jell-O, and flamingo meat. After Carter moves into Brooklyn House, Khufu becomes his roommate and trains him in basketball, Khufu's favorite game which Carter is terrible at. Khufu occasionally accompanies the Kanes on their missions and has taken a liking to their trainee and librarian Cleo due to her name ending in an O.
Leroy – The Set animal that attacks the Kanes at the Washington Monument and Reagan National Airport. Carter nicknames him Leroy and it is mistaken by mortals for a rabid moose. Unable to kill Leroy, Carter manages to banish him into the Duat, which Bast notes is a tremendous feat of magic, particularly for an inexperienced magician like Carter.
Mummy – Undead bodies that are wrapped in bandages. They can be summoned through Egyptian necromancy. In The Throne of Fire, Sadie and Walt face an army of mummies in the catacombs beneath Bahariya whose souls are trapped as they're Romans and the proper rites weren't done to send them either to the Duat or the Roman Underworld. However, Ptah arrives to help, sending an army of rats to devour the mummies. Ptah later states that destroying their bodies released the mummies trapped souls into their proper Underworld at last.
Petsuchos - A crocodile monster that is also known as the "Son of Sobek". During ancient times, it was worshipped as the sacred animal of Sobek in his temple. In The Son of Sobek, the petsuchos rampages throughout Long Island for over two weeks, eating two pegasi belonging to Camp Half-Blood. The creature draws the attention of both Percy Jackson and Carter Kane who are unable to destroy the petsuchos as it is truly immortal. Eventually, while Percy distracts the petsuchos with a miniature hurricane, Carter manages to unlock the clasp on the necklace that the petsuchos is wearing, transforming it back into the form of a three foot long baby crocodile, the form that the petsuchos had before someone had put the necklace on the crocodile. Carter and Percy theorize that the crocodile might've originally been someone's pet before being abandoned although they are unsure of how it got the necklace. Carter decides to adopt the baby crocodile, now completely harmless, as another Brooklyn House pet and a companion for Philip of Macedonia. In The Staff of Serapis, Sadie Kane realizes that Setne had released the petsuchos to test the reaction time of both the Greek demigods and Egyptian magicians and what would happen if they were brought together.
Serpopard – A creature of chaos that has the head and neck of a snake and the body of an African leopard. They have the ability to spit poison and are tremendously strong. Two attack Brooklyn House in The Red Pyramid, but are quickly killed by Bast after Sadie Kane calls upon her for help.
Shabti - Clay figurines used for multiple functions, including acting as servants for their masters in the afterlife. Other shabti serve as decoys, companions, soldiers, and even librarians or informants. Most shabti are made incomplete in some way; if their bodies are perfect, they will come to life and possibly kill their master out of vengeance. Magicians use shabti in various spells, including execrations and healing spells. Walt Stone is particularly skilled in making them and Sadie Kane has also become somewhat adept at it as well. Sadie has used her shabti as a means of communication and is noted to have created one that behaved like a Dalek from Doctor Who. Chief Lector Iskandar is also skilled at this, able to create shabti doubles of real people that have their memories and powers and are indistinguishable from their living counterparts.
Doughboy - Julius Kane's shabti whose legs he cut off so that he couldn't become real and kill him. Doughboy is used as a source of information by Julius and is gleeful at the fact that he's been captured by Set. Carter later uses him to find the Book of Overcoming Set in Paris. Needing a ride to the Red Pyramid, Carter smashes Doughboy into a coat as part of a spell to animate the coat to drive a semi-truck for them. His further fate is unknown.
Jerrod and Wayne - Two shabti magicians created by Thoth to act as a test for the Kanes when they visit Graceland. After Sadie manages to defeat them, Jerrod and Wayne shatter and their memories are sent to Thoth.
Philip of Macedonia — Amos's albino crocodile pet, later identified as a wax shabti. He lives in the swimming pool at Brooklyn House, although his ability to be transported into a clay figurine means that he occasionally is transported elsewhere. In The Red Pyramid, Amos sends Philip to rescue his niece and nephew from Sobek's crocodiles. He then returns to Brooklyn House with Khufu. In The Throne of Fire, Philip enjoys food that the Brooklyn House trainees toss him at breakfast and fights against the invading forces. In The Serpent's Shadow, Walt takes Philip with him when Brooklyn House is abandoned in favor of defending the First Nome. Philip gives Sadie and Walt a ride on his back down the Nile River and is later one of the shabti released by Walt to protect the fallen magicians.
Zia Rashid - A shabti of Zia Rashid created by Iskandar to protect her after Zia inadvertently becomes the host of the goddess Nepthys. For most of The Red Pyramid, the shabti version of Zia is the one that appears instead of the real Zia. The shabti is badly injured fighting Set and uses the last of her life force to shield Amos Kane from the destruction of the Red Pyramid. The shabti crumbles shortly thereafter, asking Carter to find the real Zia and sending her memories to Zia. After Carter finds the real Zia, she is shown to possess her shabti's memories, but at first they are more like a movie she'd watched with an actress playing her and doing things that Zia would never have done.
Magnus Chase and the Gods of Asgard
Main characters
Magnus Chase
Magnus Chase is the main protagonist of the series and is the cousin of Annabeth Chase. A 16-year-old Bostonian teenager, Magnus lost his mother Natalie Chase to a mysterious wolf attack two years prior to the events of The Sword of Summer and is forced to live in the streets with his homeless friends, Blitz and Hearth. On his 16th birthday, his uncle, Randolph informs him of his divine parentage as a son of a Norse god and his inheritance of Sumarbrander, the sword that once belonged to his father Frey. After being killed by Surt, a fire giant, Magnus is then carried to Hotel Valhalla by Samirah Al-Abbas, a Valkyrie. He then finds out that his father is Frey, the god of peace, wealth and prosperity, who belongs to the Vanir tribe of Norse deities.
Magnus is described as having blond hair that reaches his chin and haunting gray eyes that resemble his cousin, Annabeth's. He is said to look like Kurt Cobain and has asthma. His scrawny look is replaced by a more muscular persona after his death and acceptance to Valhalla. He is quite street smart due to the two years he spent as a homeless child and as a result, is not quick to trust people. Nevertheless, he considers Blitz and Hearth as the only friends he is completely loyal to, and after a while, also begins to ease up and trust Sam. He is also known to have a budding relationship with another child of Loki named Alex Fierro. He is not fiery nor quick to anger.
As a son of the god of fertility, Magnus does not excel in offensive power. Instead, he usually thinks strategically to safely escape from danger. When he does have to attack, he mainly uses the Sword of Summer, Jack, who attacks autonomously. Magnus' demigod abilities concern healing and warmth: through concentration, Magnus is able to heal even the mortally injured (though doing so often causes him to read the subject's memories) and once made a mortal (Sam's fiancé) see through Ginnungagap and into the Norse world. Magnus can also summon the Peace of Frey that can disarm everyone who is close to him.[24]
Blitzen
Blitzen (Blitz) is a 20-year-old dwarf or, more specifically, a svartalf from Nidavellir. He is the son of a Vanir, Freya, making him Magnus' cousin, and a dwarf, Bilì, who was eaten by Fenris Wolf while checking Fenris's prison rope. He is sent alongside Hearth by Mimir to watch and protect Magnus. Though he keeps it up for two years, the task fails when Magnus is killed, but Blitz continues to look for him until they are reunited in Valhalla. As a dwarf, Blitz is sensitive to sunlight and will slowly turn to stone if exposed too much, which is why he always wears a copious article of clothing whenever there is sunlight, except in Folkvanger, in which sunlight is replaced by an aura radiated by Freya instead. Instead of forging, Blitz excels in clothing design, making him a laughing stock among his fellow dwarfs, but after he wins a match against Eitri Junior, he becomes respected and eventually opens up a clothing shop. In battle, Blitz uses his creations to assist himself, including chain-mail gloves and vest. Blitz has had a strong relationship with Hearth ever since the former saved the latter's life, and the two are very protective of each other.[24]
Hearthstone
Hearthstone (Hearth) is a light elf from Alfheim. He is skinny with pale skin and with short spiky blond hair, which, when combined with his black leather jacket, jeans, and a candy cane scarf, "makes him look like a character from a Japanese anime". Hearth is deaf and can only communicate with ASL (Alf Sign Language) and he has *trauma* , though he is able to read lips. Since his "home" world is always bright, he is sensitive to darkness. Like Blitz, Hearth makes a deal with Mimir to drink water from Mimir's Well by one of the roots of Yggdrasil to gain knowledge about runes and in return has to work with him for several years. He becomes a companion and protector of Magnus from then on. Hearth is the first elf in a long time to focus on magic from runes, which he has studied extensively. He can cast various runes, though doing such consumes his energy. Eventually, he progresses to the rank of a full sorcerer.[24]
Hearth has a traumatic past, as he is effectively unwanted by his parents, who shun him for being deaf and not as great as his brother, Andiron, who died young; he is forced to face his past in the second book, when he has to collect the Skofnung Stone from his father, Alderman, who wants him to finish the blood tax imposed on him as repentance for Andiron's death. He is also reminded that sooner or later, he will have to take the othala rune from Andiron's place of death, which he planted as a reminder of his past, to complete his magic arts. In the third book, Hearth decides to take othala, using it to summon Andiron's spirit to distract his father long enough for Magnus to pierce his heart. Despite all that Alderman put him through, Hearth is shown to have conflicted feelings on his father, wanting to kill Alderman after finding him as a dragon out of a sense of mercy and then not being sure on whether or not to eat the dragon's heart and gain all of his father's knowledge and wisdom. After Magnus accidentally burns the heart in a fire, Hearth is relieved to have the burden removed from himself. His relationship with his friends helps him. and he even once calls Magnus "brother" with Magnus returning the sentiment during his flyting with Loki. At the end of the first book, Hearth is freed from servitude and begins learning runes from Odin.[25]
Samirah al-Abbas
Samirah (Sam) al-Abbas Bint Loki is a Valkyrie and daughter of Loki who selects Magnus as an einherji under Odin's order. She is an Arab American who normally wears her Valkyrie armor and a green hijab, which doubles as camouflage. She leads a double life as both a Valkyrie and a normal high schooler. She does not worship the Norse gods as she is Muslim and believes in Allah. Her family is from Baghdad, but has been raised by her grandparents in Dorchester since the death of her mother. Sam's family already had a long history with the Vikings, even before her mother met Loki; Ahmad ibn Fadlan, a historian and envoy of the Abbasid Caliph to the Kievan Rus', is one of Sam's ancestors, and the Varangians have since intermarried with Sam's family. The Norse also distrust her for being Loki's daughter.[24] Sam is married to her childhood crush, Amir Fadlan, who works in a falafel shop.[26]
In The Sword of Summer, Sam is expelled from Valhalla when her video of Magnus' Heroic death is edited by Gunilla, but later joins Magnus, Blitz, and Hearth in stopping Fenris Wolf from breaking free. She is eventually reinstated as Valkyrie and gets another job as Odin's personal aide. In The Hammer of Thor, Sam is unwillingly betrothed by Loki to Thrym in exchange for Mjolnir; in reality, Loki wants the Skofnung, with which he can finally free himself.[25] Sam is then given a task by Odin to head towards Scandinavia and personally imprison Loki back before he is able to invade Midgard and eventually Asgard. In The Ship of the Dead, Sam participates in the quest to stop the Naglfar from sailing in Niflheim and has sufficiently trained with Alex enough that she is immune to Loki's influence. The quest is challenging for her not only because of its danger, but also because she is fasting for Ramadan.
As a fighter, Sam wields a Valkyrie axe or dagger. She has also inherited her father's ability to shapeshift into animals, but doing so makes her uncomfortable, as it causes her to become more like her father. Sam wants to become a pilot and enjoys being a Valkyrie because it affords her a chance to fly (albeit through levitation, not piloting).
Sumarbrander
The Sword of Summer (Jackass) was Frey's weapon, currently wielded by Magnus Chase. After Magnus finds out that the sword is sentient, Sumarbrander decides to name itself Jack, and be referred to as a male. In battle Magnus can let the sword attack his enemies on its own or use his own strength and control the sword himself. Either way, it is Magnus who loses energy ultimately, though this loss is delayed until he next grips or sheathes Jack.
He bears a grudge against Frey, who 'abandoned' him, by giving him to Skirnir as a price for the latter bringing the former a Giantess with whom he fell in love; he summarises this by once admonishing Frey, saying 'blades before babes'.
He reached Boston with one of Skirnir's descendants during the Viking expansion, where he was lost for centuries until he was recovered by Magnus.[24]
Introduced in Magnus Chase and the Hammer of Thor, Alex Fierro is a child of Loki (mother) and Mr. Fierro (father). She/he is gender-fluid, similar to Loki, who was known to change genders in myths. She/he prefers pronouns coinciding with her/his gender at the moment rather than "they". When in Valhalla, she/he is referred to as an argr, the Old Norse word for 'unmanly,' due to being assigned male but identifying as a woman most of the time. Unlike her/his half-sister, Sam, Alex was born via Loki's female form, thus making the god her/his mother rather than her/his father. Like Sam, she/he resents her/his mother; however, Alex seems to be able to resist Loki much easier than Sam. She/he, like Magnus, is homeless, in her/his case due to her/his father disagreeing with her/his gender-fluidity. Nevertheless, she/he treasures her/his Fierro heritage, an ancient family who had lived near Mexico City as potters since before the time of the Aztecs.
In The Hammer of Thor, Alex goes to Jotunheim alongside Magnus and the others to visit Utgard-Loki and find out about Loki's plan about Sam's betrothal. She/he becomes Sam's double during her betrothal and forms a friendship with Sif. In The Ship of the Dead, Alex has trained Sam to resist Loki's influence and participates in the quest to Scandinavia to stop Naglfar from sailing. She/he grows closer with Magnus and kisses him when the group is struggling to reach Skadi's fortress in Niflheim. The kiss is recounted by Magnus during his fighting with Loki as the greatest thing to have ever happened to him. By the end of the book, she/he assists Magnus in running the Chase Space, a shelter for the homeless youth.
Alex uses a gold garrote wire as a weapon, which formally used to be a pottery wire. She/he can shape-shift into animals, like Loki, and is far more comfortable with embracing this power than her/his half-sister, Sam.[25]
Norse deities
The Norse gods fall into two general groups: the Aesir and the Vanir. All are referred to generally as "Asgardians", but the Vanir inhabit Vanaheim as often as Asgard. The Aesir are more warlike, while the Vanir are peaceful. Specifically, however, the gods tend to be distinguished by what side they fought on during the Aesir-vanir war, and not by their personal temperaments.
Aesir
The following Norse gods are considered the more warlike of the two strains of immortals.
Frigg – The queen of the Aesir and wife of Odin, the goddess of knowledge, wisdom, and forethought. As Odin frequently travels through the Nine Worlds, Frigg is left in charge of Asgard most of the time. Sam idolizes her among the Aesir as she is the glue that keeps the gods together. According to Sam, no einherji or valkyrie have ever seen Frigg in person. The Ship of the Dead reveals that she is the mother of Mallory, whom she gives a walnut capable of trapping anything inside it.
Heimdall – The all-seeing, all-hearing god of vigilance and guardian of Bifrost, the entrance of Asgard, who was born from nine mothers. He has a hobby of taking selfies, using his horn Gjallar as a phablet and a selfie stick, which tends to make him forget to directly oversee the Nine Worlds.[25]
Kvasir – An Aesir born from the saliva of the gods, created as a peace treaty following the Aesir-Vanir war. He walked through the Nine Worlds giving advice to beings, but he fell to a trap by Fjalar and Galar, who killed him and drained his blood to create the Mead of Poetry.
Loki – The god of evil and trickery. He is the father of Samirah Al Abbas. He can also become female, having turned into a mare to give birth to the eight-legged horse Sleipnir and later into a red-haired woman to give birth to the demigod Alex Fierro, who like Loki, is gender-fluid. After tricking Hod to kill Balder, he is chained to a rock with the entrails of his sons as chains with poison from a snake dripping onto his face constantly. He makes it his personal goal to break free and take revenge against the gods in Ragnarok, using his trickery to manipulate people around him even when he is incorporeal. He finally manages to break free at the end of The Hammer of Thor and begins the preparations to sail in the Naglfar to declare Ragnarok.[25] In The Ship of the Dead, despite managing to shame Magnus greatly during their flyting duel, he is overpowered when Magnus flytes him with the power of his friends long enough for Mallory to trap him inside a magical walnut. Odin later sentences Loki to be chained again to the rock.
Mímir – The god of knowledge and wisdom. He was beheaded during the Æsir-Vanir War and only his head remains alive. He is the boss of Blitz and Hearth due to a deal they made to drink from his well. The deal is nullified by Odin at the end of first book as their reward for dealing with the Fenris Wolf.[24]
Odin – The king of the Aesir, the god of royalty and magic. He is able to rewrite reality by spelling out runes, which he learned after hanging for nine days on a branch of Yggdrasil. Odin is the owner and proprietor of Hotel Valhalla where he is always away on important businesses where he searches for knowledge and leaves the important decisions to his management. His ravens and wolves represent him at meetings. In The Sword of Summer, Odin is claimed to have disappeared two years before Magnus' acceptance as an einherji, but he actually disguises himself as X the Troll, and one of Magnus' floormates. At the end of the book, Odin reveals himself and rewards Magnus and his friends for their bravery against the Fenris Wolf. He likes to give presentations.[24]
Ran – The goddess of the sea, who operates a net that collects anything that falls into the sea. She has an apple of Idun, but forgets to consume it, which contributes to her elderly appearance. Magnus and Sam manage to convince her to give them the apple and Sumarbrander, but she warns that doing so has made her and Aegir bent on attacking Magnus.[24]
Sif – The goddess of the earth and Thor's self-proclaimed "trophy wife". After losing her hair due to Loki's trick, she now has golden hair that can be melded into precious objects, inspiring the legend of Rapunzel. Sam and Alex, both Loki's children, do not like her; the former states that Sif is vain and accepts her hair replacement and title because she does not understand that Loki is merely playing with her. Alex, however, begins to have respect for her after she helps her dress for Thrym's wedding ceremony.[25]
Sigyn – Loki's wife. She reduces his punishment by collecting venom dripped by the venomous snake in a bowl, though it is never enough to alleviate them from torturing him. When Loki is about to free himself in The Hammer of Thor, she appears to make an attempt to delay the escape, but later goes with him anyway when the Asgardians come. She is present during Magnus and Loki's flyting duel; when Loki indirectly insults her by claiming that he stands by himself, she leaves the area, dealing the final blow to the flyting once Magnus points out that Loki has no one to care for him. She is described as having eyes that tear blood, as well as a perpetually blank expression.[25]
Thor – The god of lightning, storms, and strength. He has an unkempt appearance, is lazy, and is also up-to-date with modern television shows. He has red hair, huge muscles and a dirty face. He wears a sleeveless, leather jerkin and is very loud. He tasks Magnus and his friends with retrieving his staff, which was stolen from him by Geirrod. He has two talking goats, Tanngrisnir and Tanngnjostr, nicknamed Otis and Marvin. His hammer is currently missing, which becomes an important plot point in The Hammer of Thor, where he regains it.[25]
Tyr – The god of courage, law, and trial by combat. He lost his hand due to Fenris Wolf's bite. All of his children, T.J. included, are naturally inclined to accept challenges. He appears at the end of The Ship of the Dead, congratulating T.J. for stopping Loki from starting Ragnarok.
Vidar – The god of revenge, also called the "Silent One" due to his method of communicating with ASL. He is sensible and snarky, a complete opposite of his brother Thor.[25]
Vanir
These gods are generally more peaceful and dislike the warlike nature of the Aesir:
Frey – The god of fertility, warmth, and healing, the twin brother of Freya, and the father of Magnus. Frey owned a sword, Sumarbrander, which was given to Skirnir in return for his help in wooing a beautiful giantess; as a result, he is unarmed by the time of Ragnarok and will be killed by Surt. Though Magnus never meets his father until the end of the first book, he realizes that all the times his mother took him hiking through the wilderness was a way for them to get closer to Frey.[24]
Freya – The goddess of love and warmth and the twin sister of Frey. She is described as very beautiful. She presides over Vanaheim, where the other half of worthy souls go after death, and casts warmth that shines over it. Freya is the mother of most dwarves in Nidavellir, including Blitz, which happened because she bartered to (briefly) marry some dwarves in exchange for luxurious items. Freya tasks Blitz to get some earrings by challenging Junior.[24]
Njord – The god of fishery, seafaring, and crop fertility, the father of Frey and Freya, and Magnus' grandfather. He is a mortal enemy of Aegir and Ran, his influence stopping them from ravaging through the sea and reducing the mortal casualties. In The Ship of the Dead, he saves Magnus and company from being killed by Aegir's nine daughters and tells them to seek his ex-wife, Skaldi, if they want to prevent Loki from sailing in the Naglfar.
Other Norse gods
Hel – The daughter of Loki who presides over Helheim, the realm where the unworthy dead go. One half of her is a very beautiful woman, while the other is a decaying corpse. She tries to persuade Magnus to give up Sumarbrander to Randolph, but he refuses.[24]
Norns – A trio of female figures who can see the past, present, and future. They recite a prophecy to Magnus that kickstarts his journey to stop Fenris Wolf from breaking free.[24]
Fear – A minor God who assists the Mountain Giants. In The Hammer of Thor, it is sent to compete with Sam in a game of axe throwing under the guise of a Mountain Giant called Little Billy. Sam sees through the illusion and defeats it.[25]
Hotel Valhalla residents and staff
The following characters live and/or work in Hotel Valhalla and all answer to Odin. It is their duty to prepare an army for the day of Ragnarök.
Einherjar
Dede – One of Magnus' fellow new einherjar. She is prophesied to become a Thane of Valhalla.[25]
Halfborn Gunderson – An einherji who has lived in Hotel Valhalla since the Age of the Vikings over 1,200 years ago. He originated from Flåm, a small village in Norway and died in East Anglia while protecting Ivar the Boneless. He is described as "Robinson Crusoe on steroids". Having lived for a long time, Halfborn is extremely skilled and has learned many languages. He has a PhD in Germanic literature. He almost dies at the end of The Sword of Summer, but is revived by Magnus' power of healing.[24] Since The Hammer of Thor, Halfborn is dating Mallory.
Helgi Hundingsbane – A Viking from East Gothland who is the hotel manager of Hotel Valhalla and member of the Thanes where he mostly works at the reception desk.[24]
Hunding – The former King of the Saxons, the bellhop and doorman of Hotel Valhalla, and Helgi Hundingsbane's servant. Back in the year 749 C.E., Hundling and Helgi were opponents on the battlefield.

Lars Alhstrom – An einherji and son of Thor who comes to Hotel Valhalla alongside Magnus. He died trying to free trapped people at sea.[24]
Mallory Keen – An Irish einherji and daughter of Frigg. A member of the IRA, she died during The Troubles while attempting to deactivate a bomb she planted to a school bus due to Loki's trick. This incident sparked her hate of Loki. She is foul-mouthed and quick to criticize someone, though T.J. explains that those are her expressions of affection. She has a love/hate relationship with Halfborn Gunderson, criticizing him as a "disgusting Swede", yet is in tears when he almost dies at the end of The Sword of Summer.[24]The Hammer of Thor reveals that the two are dating.[25]
Thanes – The Thanes are people who have been chosen to accompany Odin to Valhalla. They consist of historical figures who Odin has selected. When Hotel Valhalla was established, Odin made them Hotel Valhalla's board of directors. Besides Helgi and Gunilla, among the known Thanes are:
Ernie Pyle – Member of the Thanes. He was a Pulitzer Prize–winning American journalist.
Eric Bloodaxe – Member of the Thanes. He was a Norwegian ruler.
Erik the Red – Member of the Thanes. He was a Viking who founded the first Viking settlement in Greenland.

T.J. is the first of Magnus' floormates to befriend him. He is very energetic and likes to capture hills, which he originally did as a private of the 54th Massachusetts. His backstory and cause of death were revealed in The Ship of the Dead: he was challenged by a Confederate whom he killed at the cost of attracting other Confederates to ambush him, though the act encouraged T.J.'s mates to participate in the successful Second Battle of Fort Wagner. Due to Britain's decision not to support the Confederates, he is very grateful to English people and constantly thanks everyone he meets in York.
X – A half-troll and one of Sam's more controversial choices. His skin is grey and covered with warts and welts. He is called X as his real name is unpronounceable although Magnus describes that it is very long and the letter K repeatedly appears in it. He died in Chicago breaking up a dog fighting ring. At the end of The Sword of Summer, it is revealed that X is actually Odin in disguise.[24]
Valkyries
The Valkyries are Odin's handmaidens who choose which slain Heroes should be brought to Hotel Valhalla. They also work as waitresses during feasts and provide room service to its inhabitants.
Gunilla – A daughter of Thor, a member of the Thanes, and the leader of the Valkyries. She is spiteful towards Sam, because Sam is a daughter of Loki. She once dated a son of Loki who turned out to be a spy of his father. When Magnus escapes Valhalla, Gunilla leads the expedition to capture him, even after he and his friends release her from the giants' imprisonment. She later sacrifices herself while fighting Surt while Magnus re-imprisons Fenris Wolf. She carries a bandoleer of ball-peen hammers.[24]
Margaret and Irene – Gunilla's two valkyrie aides. Magnus does not find out their names until they have been killed by the fire giants at the end of the first book.[24]
Other Norse beings
Norse humanoids
Draugr – Draugr are Norse zombies, usually those of Vikings. They are also called Wights.[25]

Arvid – One of Gellir's protectors.
Dagfinn – Gellir's secretary.
Knut – One of Gellir's protectors.
Dwarves (Svartalfar) – A race of Norse Dwarves that live in Nidavellir. The dwarves, like humans, are mortals, though they cannot live in a world with sunlight, as it turns them to stone. This process can be reversed with running water. They are a matriarchal society and generally have an appreciation for crafting and inventions, naming each and every one of them. The dwarves believe they are descended from maggots, which explains why they prefer to live underground.[24]
Andvari – A dwarf who lives in Alfheim in the form of a fish. He holds a ring that can give its wielders immense wealth, yet will inflict a curse that robs them of all of their sanity and brings out their worst aspects.[24]
Fjalar and Galar – Trickster dwarves who operate a boat that leads to the prison of Fenris Wolf. Anyone who barters with them usually end up stranded on the island.[24]
Junior – A grumpy old dwarf who hates Blitz for shaming his father, who built Fenris Wolf's prison. He challenges him to a smithing challenge before he gives him Andskoti and jewelry for Freya. He fails because of Sam's intervention, but Blitz decides not to execute Junior. Junior is more than 500 years old.[24]
Nabbi – A bartender in Nidavellir. He is also one of the members of a jury for Blitz and Junior's smithing challenge.[24]

Alderman – Hearth's cold, vain, and abusive father. He prefers his other son, Andiron, over Hearth, and when the former died, he forced Hearth to collect blood tax to pay for Andiron's death, leading the latter to run away from home. He is given Andvari's cursed ring to complete the tax, which causes him to exhibit the worst of his vain nature.[25] By the third book, the ring has transformed Alderman into a ring dragon who lives in a cave near the well where Andiron died. Magnus manages to stab and kill him, allowing him, Blitz, and Hearth to take the whetstone and the ring.
Andiron – Hearth's younger brother, who was killed by a Brunnmigi while he is playing with Hearth near a well in the family estate, and his death is used by Alderman to force Hearth into paying a hefty sum of blood tax for repentance. A portrait of Andiron hangs in the family's living room.[25] Hearth summons Andiron's spirit in the third book as a distraction for Magnus to kill Alderman. Before disappearing, he urges Hearth not to dwell in the past and instead move on.
Officers Sunspot and Wildflower – Two elven police officers patrolling loiterers in Alfheim.[25]
Hulder – Forest spirits who inhabit Alfheim. They look like the light elves, except that they sport cow tails. They live in Alfheim like the elves, mostly as servants or hidden in forests. By elven law, they are prohibited from hiding their tails or leaving the property of their masters.[25]
Inge – A female hulder serving the residence of Alderman, Hearth's father. She is miserably submissive to Alderman, despite the fact that he frequently abuses her. She is in love with Hearth but is too shy to confess it. Her mother had once served the family before her.[25]
Giants (Jötunn) – The Jötunn are the Norse Giants of which there are many types. Most of the Jötunn are either at human size or are incredibly large. Throughout the series, Mountain Giants, Frost Giants, and Fire Giants are all encountered and referred to generally as "jotunn". While some Jötunn are mortal, some are not. While some look more human, others are at gigantic proportions. Each of the Jötunn has different features that include but are not limited to claws, fangs, misshapen faces, extra heads, and non-human shapes. The Jötunn are also expert shapeshifters where they can change forms at ease.[25]
Aegir – A sea giant and husband of Ran, with whom he has nine daughters who live with him in his underwater residence. In The Ship of the Dead, as Ran has told him to kill Magnus due to a trickery she is subject to, Aegir confines Magnus and his friends once they are all captured by his daughters. However, he decides to let them go after Magnus promises that he will defeat Loki in a flyting duel and give him a sip of Kvasir's Mead.
Daughters of Aegir – Aegir and Ran have nine giantess daughters who obediently follow their father's wishes. They are: Blodughadda, Bylgja, Drofn, Dufa, Hefra, Himmingleva, Hronn, Kolga, and Ud.
Baugi – Suttung's brother. He and Suttung are summoned to Fläm when the sip of Kvasir's Mead is stolen by Magnus, Sam, and Mallory. He chases Sam and Mallory but is killed by Halfborn, whom he angers by threatening to destroy Fläm, his hometown.

Gunlod – Suttung's daughter. She is imprisoned in a cavern in Fläm due to having let most of Kvasir's Mead stolen by Odin, who seduced her. She hands the rest of the mead to Magnus and his friends, but informs them too late that doing that would summon her father and uncle to Fläm.
Harald – A Frost Giant who operates a boat in the port of Boston. He helps Magnus and Sam set a bait for Jormungand to summon Ran. He is easily swayed by red gold, which can bribe him to do almost anything.[24]
Herg and Berg – Members of Tiny's bowling team. They compete with Magnus and Alex in Utgard-Loki's bowling championship.[25]
Hrungnir – A 20ft. stone giant with a limestone appearance and rubble on his long hair and beard. He lives in York. Before Hrungnir gives Magnus information about Kvasir's Mead, he challenges him, Alex, and T.J. to a duel: he would face T.J., and his stone creation would battle Alex's creation. The duel ends in his death, though he manages to deal a magical shrapnel in T.J.'s forehead that is unable to be removed.
Skaldi – An ice giantess and Njord's ex-wife. She lives in a castle located on the border between Jotunheim and Niflheim, giving her a clear view of the Naglfar, the ship that Loki would board during Ragnarok. Skaldi provides Magnus and his friends a respite before their assault of the ship.
Surt – The king of the Fire Giants of Muspellheim. He is destined to kill Frey using Sumarbrander and burn Nine Worlds during Ragnarok. Though he manages to kill Magnus, Surt's nose is cut and does not recover by the time of his second encounter with Magnus, where he is expelled back to Muspellheim.[24]
Suttung – A giant and Loki's assistant in the construction of the Naglfar. He hides a sip of Kvasir's Mead in a cavern in Fläm which also imprisons his daughter Gunlod. He is summoned back to the village when the mead is stolen by Magnus, who kills him.
Thrym – The king of the Mountain Giants. He stole Mjolnir sometime before the events of the series and in The Hammer of Thor, makes a deal with Loki to trade it in exchange for Sam's hand in marriage and the Skofnung Blade as the mundr, or the bride-price. At the end, however, he has to face the fact that his sister, Thrynga, has been planning to usurp him as ruler of the Earth Giants, and the fact that Loki has never wanted to honor his deal and give Skofnung to him. He is killed by Vidar.[25]
Thrynga – Thrym's sister and his only surviving family member after Thor killed them all when he was humiliated into becoming his bride. She is manipulative and wants to take the throne of the ruler of the Earth Giants from her brother. She arranges for the wedding between Thrym and a daughter of Loki, intending to steal Mjolnir and Skofnung for herself. She is incapacitated by Magnus, then finished off by Thor.[25]
Tiny – A Mountain Giant who in The Hammer of Thor offers Magnus and company support in Utgard Loki's bowling championship in exchange for taking his bag to the Utgard Lanes.[25]
Utgard-Loki – A Mountain Giant and the King of Jotunheim. He is sometimes mistaken for the more famous Loki, which he hates. As an eagle, Utgard-Loki forces Magnus to retrieve an apple of Idun for him, which reverts him back to his youthful state.[24] In the second book, he attempts to prevent Loki's escape by cryptically warning Magnus, though the latter falls into the trap, anyway.[25]
Troll - The Trolls are creatures in Norse folklore.
Norse creatures
Brunnmigi – A wolf-like creature who lives inside a well in Alfheim. A Brunnmigi was responsible for the death of Hearth's younger brother Andiron. It was then killed by the brothers' father Alderman who used its fur as a container for the blood tax Hearth needs to collect as repentance.[25]
Eikthrymir – A stag residing in Hotel Valhalla. It constantly pours water into a lake, which serves as the source of all water in the Nine Worlds.
Fenris Wolf – The lupine son of Loki and the brother of Hel and Jormungand. He was a terror in times past and the gods could only chain him up with the help of the dwarves to stop him; even Tyr had to lose his hand against the wolf, while Blitz's father, Bilì, lost his life while checking his prison on Heather Island. During Ragnarok, Fenris Wolf is destined to kill Odin and eat the sun. He is the focal point of The Sword of Summer, as the goal of Magnus and his friends is to stop Fenris Wolf from breaking free of his prison, which needs to be rebuilt. They manage to imprison him again at the end of the book.[24]
Geri and Freki - Odin's two wolves who act as his representatives. Their name means either "the ravenous" or "greedy one".
Heidrun – A goat whose milk is the source of the mead that serves the gods. Like Eikthrymir, Heidrun resides in Hotel Valhalla.[24]
Huginn and Muninn – Odin's two ravens who act as his spies as well as representatives in giving missions to his special aides, such as Sam, when he is not around. Their names mean "thought" and "memory", respectively. Helgi specifically notes that the two do not like to give PowerPoint presentations, unlike Odin.[24]
Jormungand – The serpentine son of Loki. He is a snake who circles over Midgard and is so long he must hold his tail in his mouth to prevent destroying Midgard. He is lured by Magnus and Sam to cause a ruckus in the sea big enough to summon Ran. Even after being lured, Jormungand is still half-asleep, but Ran warns that waking him up completely would cause Ragnarok, where he is destined to kill Thor.[24]
Lindworm – Large, fearsome dragons with bat wings who reside at the roots of Yggdrasil. One of them is sent by Loki to catch Magnus and his friends during a Valhalla training off-guard.[25]
Nøkk – Water spirits who play sad music through violins, sending its listeners to despair. In The Hammer of Thor, Alderman summons a horde of Nøkk to attack his guests and Magnus and company.[25]
Otis and Marvin (Tanngrisnir and Tanngnjostr) – Two goats who pull Thor's carriage. They are also used as source of food and continuously resurrect after being killed unless their bones have been broken. Marvin is more pessimistic and angry than Otis, and likes to criticize him.[24]
Ratatosk – A gigantic squirrel who runs around Yggdrasil, delivering hateful messages between the eagle at the top and the titanic serpent Nidhogg below. It is also tasked to capture intruders who enter and leave Hotel Valhalla without permission. Ratatosk is able to emit sorrowful callings to people, which Magnus describes as much worse than simply being gnawed by it.[24]
Saehrimnir – A creature whom the Aesir and einherjar kill every night for food only for it to rematerialize the next morning. Its flesh's taste depends on what its eater wants it to taste like, and even has a vegan tofu option.[24]
Stanley – An eight-legged horse whom Sam speculates is a child of Odin's steed Sleipnir. He helps Magnus and his friends on several occasions.
Vatnavaettir – Vatnavaettir are water horses. They are called each-uisce in Irish. Some of them attack the Big Banana in York, but Sam manages to tame them, allowing her to summon them to scurry her and the others after their successful capture of Loki in Niflheim.
Mortals
Mortals are human characters who live outside of the world of magic and gods, though some may be aware of their supernatural surroundings.
The Jackson family
Sally Jackson – Percy's mother, initially married to Gabriel Ugliano and later to Paul Blofis.[7] In The Lightning Thief, she works in a candy shop. When she was younger, she aspired to be a writer. She is nearly killed by the Minotaur, but is discovered to be alive in the clutches of Hades. Percy travels to the Underworld to free her.[2] In The Titan's Curse, Percy realizes she can see through the Mist, which she admits may have attracted Poseidon to her. Sally appears in all of the first five books. The Hidden Oracle reveals that she is seven months pregnant with Percy's baby half-sister. In the Magnus Chase and the Gods of Asgard book The Ship of the Dead, it is revealed that Sally has given birth and that she called her daughter Estelle, after her late mother. In the film adaptation, she is portrayed by Catherine Keener. In the musical, she is portrayed by Zakiya Young (2014), Allison Hunt (2015), Carrie Compere (2017), and Jalynn Steele (2019). In the TV series, she is portrayed by Virginia Kull.
Gabriel (Gabe) Ugliano – Sally's first husband and Percy's stepfather. He is described as a loathsome man who is rude to Percy and demanding and rude toward Sally. It is implied that he was physically abusive to her as well. Percy later learns that Gabriel's strong human stench hid Percy and his mother from detection by monsters. At the end of The Lightning Thief, Percy's mother uses the severed head of Medusa to turn Gabe to stone. Sally then sold Gabe's petrified body as a poker-playing statue to the Soho art gallery. In the film adaptation, he is played by Joe Pantoliano.[2] In the TV series, he is portrayed by Timm Sharp.[27]
Paul Blofis – Sally Jackson's boyfriend and later second husband, a high school English teacher whom Percy describes as looking like a detective from a police show. Percy and his mother eventually tell Paul the truth about the gods, and he only half believes them initially. But when Percy, Nico, and Mrs. O'Leary come unexpectedly to Sally's apartment, Paul fully believes and thinks it's "awesome". He is a competent swordsman from stage combat training in college, and he assists in the fight to save Olympus in The Last Olympian.[7] Percy had first referred to him as "Blowfish" and as did Poseidon when he first heard about him.
Estelle Blofis – Sally and Paul's daughter and Percy's baby half-sister, named after her maternal grandmother. She was born sometime between the events of The Hidden Oracle and The Ship of the Dead. Babysitting her has added to Percy's workload, causing him to visit Camp Half-Blood less often. In The Chalice of the Gods, Sally reveals her pregnancy to her son and tells him that Estelle's expected due date is March 15.
The Chase family
Caroline, Emma, and Aubrey Chase – Randolph Chase's nuclear family consists of a wife named Caroline and two daughters, Emma and Aubrey. All of them perish in a storm while accompanying Randolph in locating Sumarbrander near the coast of Boston. Loki has since promised to Randolph to return them to him should he assists the former to break free from his imprisonment. Emma was designated as Randolph's successor as researcher of Norse artefacts.
Frederick Chase – Annabeth's father, a professor of military history. He first appears in The Titan's Curse. He owns a Sopwith Camel. He and his daughter have had many disagreements, which caused her to run away from home at age seven. He lives in San Francisco with his wife and two sons. In The Titan's Curse, he battles monsters on the Princess Andromeda with bullets formed from celestial bronze, and, at the end of the book, is able to mend his relationship with his daughter. Frederick also appears in the Magnus Chase & the Gods of Asgard series, where he is called by his brother, Randolph, to visit Boston and search for his long-estranged nephew, Magnus who had been missing for two years, after the death of his mother/ Fredrick and Randolph's sister Natalie.
Mrs. Chase – Frederick's wife and Annabeth's stepmother. She is an Asian woman and the mother of Annabeth's two half-brothers, with whom Annabeth barely has a relationship. She had a dispute over the trouble monsters caused when hunting Annabeth, and that was one of the factors that led Annabeth to run away from home at the age of 7. Though Annabeth describes her in a negative light, Percy is stunned when he actually meets Mrs. Chase, because she is kind and even wants Percy to tell Annabeth that she still has her home in San Francisco.
Bobby and Matthew Chase – The sons of Fredrick and Mrs. Chase and Annabeth's younger half-brothers.
Natalie Chase – The younger sister of Randolph and Frederick, the aunt of Annabeth and the mother of Magnus. She distanced herself from her brothers and lived with Magnus as a single mother until her death at the hands of the wolves of Fenris Wolf when Magnus was 14 years old. She liked to walk with Magnus through sunlit parks, which Magnus realizes much later is a way for them to get closer with his father, Frey.
Randolph Chase – Magnus' and Annabeth's uncle and the older brother of Frederick and Natalie. He was a professor of history at Harvard before being expelled for theorizing on the location of the first great Norse settlement in North America. He deliberately distanced himself with from all of his family when Magnus was 6 years old. Randolph had lost his wife, Caroline, and two daughters, Emma and Aubrey, in an attempt to search for the Norse boat. Randolph is secretly in league with Loki, who wants Sumarbrander. In The Hammer of Thor, he works in freeing Loki with Skofnung Blade and falls to a hole that leads to Helheim. Magnus discovers that Randolph has designated him and Annabeth to inherit his property, including his mansion, which Magnus converts to a shelter for homeless youth at the end of The Ship of the Dead.
The Valdez family
Aunt Rosa – Leo's aunt. She blamed Leo for causing the death of her sister, Esperanza. She turned his whole family against him and called him "El Diablo" (The Devil). She refused to take him in and sent him to a social services home, which he ran away from. In The Mark of Athena, Leo sees Nemesis as Aunt Rosa, as Nemesis takes the form of the person whom the viewer has the most hatred for.
Esperanza Valdez – Leo's mother. She was a trained mechanical engineer who worked at a machine shop and as an inventor. She was killed in a fire caused by Gaea and only appears in flashbacks. She was compassionate and hard-working and was described as pretty, but not delicate.
Sammy Valdez – Leo's great-grandfather and Hazel's former boyfriend. He is described as looking identical to Leo. He and Hazel studied in a segregated school for the colored, and Sammy defended Hazel whenever she was accused for being the daughter of a witch. Hazel received her first kiss from Sammy. However, the two separated when Hazel had to move to Alaska with her mother and never met with each other again since Hazel died shortly after. Though Hazel was led to believe that Sammy moved on quickly, a flashback she has in The Mark of Athena makes her realize that Sammy remembered her well into his old age and had made the then newborn Leo promise to meet with her on his behalf.
The McLean family
Thomas McLean – Tristan's and Piper's late father and grandfather, respectively. He was the one who gave Piper her name. Thomas believed in Cherokee myths, which are quite similar with Greek mythology.
Tristan McLean – Piper's father, a movie star who was one of Aphrodite's lovers, but did not at that time know that she was a goddess. He was captured by Enceladus in The Lost Hero, but Piper and her friends managed to save him. At the end of The Lost Hero, he is said to be back at work, though he does not remember the events of his capture. Like Piper, he identifies as Cherokee.
Jane – Jane is Tristan's assistant. Piper dislikes her for taking Tristan's already little attention to bond with his daughter away from her. Through charmspeak, Jane is controlled by Medea to lure Tristan into Mount Diablo where he is kidnapped by Enceladus, and then shooing Piper away so she could not interfere. Nevertheless, Piper manages to discover the trick and rescue her father. Afterwards, Jane is fired and replaced by Mellie the cloud nymph.
The Al Abbas family
Ayesha Al Abbas – Sam's late mother who worked as a doctor. Loki was one of her patients, and their intimate relationship that resulted in Sam's birth was resented by her conservative family due to its illegitimacy. She died when Sam was a child, and her responsibility for Sam was taken by her parents.[24]
Jid and Bibi – Sam's maternal grandparents. They are natives of Baghdad and immigrated to the United States before Sam was born.[24] Jid and Bibi took care of Sam after the death of their daughter, Ayesha. Sam mentions that the two are strict on her education and impose a night curfew on her. They do not know about Sam's current occupation as a Valkyrie until Loki tells them in the events of The Hammer of Thor, and even then, due to their mortal mind, they forget about it quickly.[25]
Amir Fadlan – Sam's fiancé. Their betrothal is by arrangement, though Sam says that she fell in love with him when she was 12 years old, at a very young age. Like Sam, Amir is an Arab American descendant of Ahmad ibn Fadlan and thus is related to her. He is the son of Abdel, the owner of a falafel shop that Magnus frequents. In The Hammer of Thor, Amir is shocked upon learning Sam's double life and at first disheartened when she appears to be breaking off their engagement. With his power, Magnus manages to make Amir able to break through the mist of Ginnungagap and see the Norse world. Sam later states that the two have sorted the misunderstanding and retained their engagement.[25]
Bullies
The following people have harassed the main characters:
Nancy Bobofit - Percy and Grover's schoolmate in Yancy Academy in The Lightning Thief. She is a bully who frequently torments Grover and gets into conflicts with Percy. However, she was favored by Mrs. Dodds/Alecto, which irritates Percy. In The Lightning Thief, she was throwing food at Grover when suddenly she was doused in water from the fountain (later revealed to be Percy's water powers). After the incident, she avoided Percy. In the TV series, she is portrayed by Olivea Morton.
Matt Sloan - Percy and Tyson's schoolmate in Meriwether College Prep in The Sea of Monsters. He frequently targets Tyson for his awkwardness and clumsiness, which comes into direct conflict with Percy. He has a chipped tooth from running his family's extremely expensive car into a "Slow down for Children" sign". He instigated dangerous events during their English exam and was the opposing team captain to Percy in the dodgeball game. When Percy was looking at a picture of Annabeth he had inside his notebook, Matt and his jerk gang proceeded to bully him for it. He also made six friends on the last day of school, who were revealed as Laistrygonians. After Tyson defeats the monsters in the dodgeball game, Sloan blamed Percy for the incident which gets him expelled and temporarily on the run from the police.
Isabel - Piper and Leo's schoolmate in the Wilderness School. She teases Piper for never meeting with her mother and for being a Cherokee, not knowing that Piper is the daughter of Hollywood star Tristan McLean.
Rufus - Hazel and Sammy's schoolmate in St. Agnes Academy for Colored Children and Indians during Hazel's first life. He was the leader of bullies who called Hazel a freak for summoning cursed stones and for being the daughter of a witch, but was always stopped by Sammy before he could hurt her even further.
Others
Barry al-Jabbar – A family friend of Sam and Amir who teaches the former piloting. In The Hammer of Thor, he escorts Magnus and company to Boston from Cape Cod and is briefly possessed by Utgard-Loki, who tells Magnus to visit him.
Beryl Grace – Thalia and Jason Grace's mother was a television actress with whom Zeus broke his oath not to have more human children. Thalia describes her as flighty, demanding and neglectful of both her children, and she would have run away from home earlier had Jason not existed. Beryl offering Jason to Hera's patronage, however, was the last straw that led Thalia to abandon her. Her stress turned her into alcohol, and she died several years before The Lightning Thief in a car accident. Melinoe impersonates her to instill fear in Thalia in the short story "Percy Jackson and the Sword of Hades" in The Demigod Files. In The Blood of Olympus, Jason encounters her mania, who wants her son to return to her so they can be a family again, an offer that Jason rejects. She then disappears in a hiss or a sigh of relief.
Cade and Mickey — Two thugs sent by Nero to rob Apollo, although Meg is able to easily drive them off. Cade is described as tall and red-haired, while Mickey is short and blond-haired.
Emma and Liz — Sadie Kane's human friends from London. They stay with Sadie in The Throne of Fire during Babi and Nekhbet's sudden attack. Sadie describes Emma as "what an Indian daughter of the singer Elton John might look like", and Liz as a "boy-crazy redhead".[22]
Officer Gómez – A Bostonian police officer. He wants to capture Magnus.
Howard Claymore – A mortal who appears in The Demigod Diaries story Son of Magic, written by Rick Riordan's son Haley Riordan.[28] He is a scholar and author with theories about death; he is approached for help by a son of Hecate called Alabaster Torrington who is fleeing the consequences of siding with Kronos in The Last Olympian. Claymore later sacrifices himself so Alabaster can use an incantation to destroy his monster half-sister Lamia who is chasing him. Hecate brings him back to life in an imitative human body so that he can live on as Alabaster's protector.
Julian Ramirez-Arellano – Julian is the father of Reyna and Hylla. Julian was a former soldier in Iraq before the birth of his eldest daughter. After he had Reyna, he started getting paranoid. He thought that his daughters were going after him and he eventually became a mania. One day, he attacked Hylla, knocking her out, and Reyna took a sword and killed what was left of him. Reyna and Hylla then fled from San Juan, Puerto Rico, soon after.
May Castellan – May is Luke's mother. Like Rachel Dare, she could see through the Mist. She went insane during a failed attempt to become the Oracle.[7] She lives in the house where she had raised Luke, alternating between cheerful expectation that he will return home and visions of his terrible fate. In The Last Olympian, Hestia reveals to Percy that Luke's mother, May Castellan, was a mortal woman blessed with the rare ability to see through The Mist, a magic substance that keeps mortals from seeing the Gods. Because of this gift, she attempted to become the new Oracle of Delphi, but was rejected. Chiron inferred that the Spirit of Delphi rejected her because she had already given birth to a child, and the Oracle was supposed to be a virgin (in reality it was due to the Curse of Delphi placed upon the former Oracle by Hades still being active). She survived her encounter, but became mentally unstable, seeing small pieces of Luke's future.
Maurice and Eddie – Two employees of Kindness International Humane Animal Transport, encountered by Percy, Annabeth, and Grover in The Lightning Thief.
Mr. and Mrs. Faust — Ruby Kane's parents, Carter and Sadie's maternal grandparents. They live in London. The two shun the magical world and take custody of Sadie, blaming Julius Kane for Ruby's death. They raise Sadie in an apparent normalcy but do not like her father or brother. The two are possessed by the gods Nekhbet and Babi in an attempt to test Sadie's resolve when she begins to pursue the Book of Ra. Mrs. Faust, usually called "Gran" by Sadie, is described as frail with curly gray hair, and a terrible cook. "Gramps" is a large, loud former rugby player. Both have been kind to Sadie, though neither is much like their daughter Ruby, her mother.
Maria di Angelo – Nico and Bianca's mother, and daughter of an unnamed Italian diplomat. She died when Zeus struck the hotel she was staying in with lightning in an attempt to kill Bianca and Nico. Melinoe impersonated her to scare Nico. In The Sun and the Star, Hades arranges for a dream visit by Maria and Bianca's spirits so that Nico can gain closure on their deaths.
Marie Levesque – Marie is Hazel's mother. She was manipulated by Gaea into helping raise Alcyoneus. She died in 1942 along with Hazel. She was sentenced to the Fields of Punishment but Hazel made a compromise with the judges so they could both be sent to the Fields of Asphodel. In The House of Hades, Hecate reveals that she was Marie's mentor, teaching her magic.
Mr. Dare – Rachel's father. He is the very wealthy owner of a land development company, and he first appears in The Last Olympian. Rachel hates her father because of his job, and he supported Rachel and loved her very dearly going to finishing school.[7]
