Volume One
Sixteen years before the start of the series, a spaceship crashes on Earth. A group of humans investigates the accident and finds an alien couple with an infant. With the father already dead and the mother on the verge of dying, the group takes the baby away.
In New Mexico, a young girl named Raven wakes up from visions of the spaceship crashing. She does not believe her dreams mean anything, but her grandfather disagrees, telling her that it is time for her to go out to the world. In Monument, Oregon, four children start their first day of high school. Tara Markov, a troubled child with an alcoholic mother, Garfield "Gar" Logan, a boy worried about skipping two grades, Victor "Vic" Stone, a boy whose mother, Elinore Stone, has high expectations for him, and Joseph "Joey" Wilson, an extremely gifted boy who finds high school boring.
Throughout the rest of the day, the children find out that they have superpowers. Vic discovers a liquid metal trying to cover his body, Tara has geokinesis, and Gar's skin turns green and becomes catlike in appearance after coming in contact with his pet cat. The moment their new capabilities fully flourish, they all say "Am Starfire. Need help" at the same time. Back in New Mexico, Raven's grandfather takes her to a secret location. Along the way, she tells him that she has been dreaming with the four children. A female being also appears in her dreams. They arrive at a cave where Raven's grandfather has been recording his own visions, which tell him that Raven will be the one who saves the teens.
The children's parents come together in secret, seeming to know something that the kids do not. Elinore tells them to contain the situation, but everybody is having doubts. Steven, Gar's father, even threatens to call the police, prompting Elinore to kill him. Slade, Joey's father, tries to back out, but she threatens to tell Joey of his shady past if he does not cooperate. She knows someone has been triggering the children's abilities and plans on stopping it.
At the beach, the children reveal that they've been seeing visions and have been searching for familiar spots. They come to accept that their parents are involved somehow. Joey tells the rest that he has not received any powers. Slade appears in uniform as Deathstroke engaging the children in a fight. During the struggle, he tells them the people they call their parents are not really related to them. Somewhere else, the other parents are revealed to be part of STAR Labs. They keep the alien baby, now all grown up, captive. They try to keep her heavily sedated, but she manages to contact Raven, prompting her to transport her astral self to the fight. The alien strikes Deathstroke in the right eye and ends the battle before returning home. Elinore's higher-ups threaten to kill the alien if she cannot control her in an hour. Even though she tells them that "Starfire" is too important to terminate, she is told that "Blackfire" project is still ongoing.
The children locate the STAR Labs facility underneath a nearby lighthouse and begin to hear Starfire's voice. Within a room with the name "Titans Project" on its door, they find incubators specifically made for them and a sea creature-like boy surrounded by turtles in a tank. They also encounter Elinore surrounded by men dressed like Deathstroke. Elinore tries to reason with the children with the men subduing anyone who tries to use their abilities. She tells them that their abilities came from elements from Starfire and the ship that brought her to Earth. After Gar finds out his father is dead, he lashes out at Elinore and a fight ensues. Joey, calling himself Jericho, sides with Elinore and uses his body-jumping capabilities. Deathstroke tries to intervene and the struggle ends with Jericho's throat accidentally slit by his father. As a means of saving his life, Jericho jumps into his father's body.
The children find Starfire and release her from her cell. Enraged, Starfire kills Elinore and leaves, telling them that they're not who she's looking for. Distraught, Vic, Gar, and Tara worry about their futures. Rita suggests they head to Utah, where another facility and the head of the entire project, a man named Caulder is located. She also suggests that they should bring the sea-creature boy, named Tempest. The children leave STAR Labs and disappear. Four days after the incident, Raven appears worried about not having dreams of the group. She enters a cave and finds Starfire asking for help.
Volume Two
Tara, Vic, Gar and Tempest hide out in an abandoned house in Seattle, eluding the police and stealing food and medicine to survive while Vic's metallic condition worsens. Slade Wilson, still possessed by Jericho, breaks into a high tech complex, disables a number of guards and confronts Niles Caulder, the head of the project that empowered the children. He offers to lead Caulder right to Starfire.
Starfire takes refuge with Raven at her New Mexico home. She links minds with Raven and shows her Tamaran and how she came to Earth. After an attack on their world, Starfire's parents got into a space ship and flew to Earth with their baby daughter. She came to New Mexico knowing Raven can hide her from the aliens searching her. Caulder instructs his chief scientist Joshua Clay to send a Doom Patrol unit with Jericho to New Mexico and retrieve Starfire. He also orders to send The Titans to Seattle to retrieve Tara, Vic, Gar and Tempest. The Titans are Wonder Girl (a young black female with superhuman strength), Kole (who creates crystal) and Impulse (a super speedster). The well-trained Titans fly to the teenages' hideout and easily defeat them.
Raven senses the trouble in Seattle, but before she and Starfire can consider going there to help, the Doom Patrol unit appears. They hurt Raven's grandfather while entering the house, prompting Starfire to attack them with her energy blasts. Jericho tries to possess Raven, but she traps him in her own mind. She then stops Starfie from killing Slade, revealing the alien's real name, Koriand'r, in the process. He reveals Caulder's plan for taking over the US government. They involved using Starfire's DNA to create both the four children, who were given normal lives, and the Titans, who were trained and brainwashed from birth to obey Caulder and believe he's their father. Caulder blackmailed all the people involved in the project to serve him and never leave the organization.
The captured four are brought in as planned. Slade, pretending to be Joseph, reports in and says he and the Doom Patrol captured Starfire, killed Raven and are sterilizing the area before bringing Starfire in. Caulder greets them all wearing "the Robotman", an exo-skeleton that allows him to walk. He sends the Titans off for debriefing and tells the four captured teens that they will become his Titans as well. He locks them up and prepares for the arrival of Slade and Starfire. Once in Caulder's presence, they drop the ruse and start attacking the security. Raven prevents Starfire from killing Caulder and takes her to the captive children. A fight with the Titans starts, but Raven is able to show Impulse the truth. Kole chooses to unlock the power damping collars on Gar, Tara and Tempest on her own free will. Raven mentally stops Wonder Girl from fighting and they all turn against Caulder. Impulse races through the complex and brings the others to see the horror he found: their dead cloned forebears.
They confront Caulder and demand answers. Caulder responds by releasing Subject 8: Starfire's clone Blackfire. She is an uglier version of Kory, and hates her instantly. As they fight, Tara finds and frees Vic, who had fallen into a metallic coma. As the battle with Blackfire rages, Jericho emerges from Raven and takes over Blackfire's body. He continues the attack until Vic and Tara enter the fray. Now free of the metal, Vic uses a huge power robot body that does his bidding while letting him remain flesh and blood. They fight Jericho off as a group until he chooses to flee. Raven teleports the others away before the police arrive. Slade finds a despondent Dr. Clay sitting beside an empty chair. Jericho/Blackfire took Caulder and fled for parts unknown.
The group flees to New Mexico, where they make a home for themselves. Raven shows them her dream cave, where she drew images of each of them based on her visions. Gar and Kole seem to have formed a relationship. Vic reveals that he and the robot body he calls Rover can't be apart or he falls back into the metallic coma. Tara tells him that she won't leave him alone. Wonder Girl and Tempest develop a friendship as well. Wally loves having the freedom to run that New Mexico affords.
Raven and Starfire look online and discover that Caulder is still missing, but his entire Star Labs operation has been shut down. Dr. Clay is taken away by the authorities. Raven confesses to Starfire that during the fight, she may have dropped the mental shield around Starfire and that those searching for her might find her in the future. Starfire says that if they come, they'll fight them together. Raven's grandpa has a bonfire for all of them. The group is happy to be together but nervous about what will happen next. Raven tells them that for the past two years, she's awakened screaming from nightmares, but since they arrived in New Mexico, all her dreams have been good. Her final words are: "And all of you were in them".
