This is a list of the many characters from the animated television series Johnny Test (including its revival).
Hugh Test (father) Lila Test (mother) Susan and Mary Test (sisters) Dukey (pet)
Jonathan "Johnny" Test is the main protagonist of the show, the brother of Susan and Mary and the youngest child of Hugh and Lila. Johnny is 11 years old and best friends with his dog, Dukey. He is a mischievous, egotistical, and unpredictable young boy who's often called the "kid with the flaming hair" due to having scarlet red highlights in his blonde hair. Johnny typically wears green cargo pants, a navy blue jacket over a black T-shirt with a trefoil symbol, a watch (he rarely uses), and black hi-top sneakers. Johnny can live any kid's dream because of his genius sisters, only to find that some aren't worth living. He tends to be showing hyperactivity and laziness quickly. In the course of these escapades, he often messes with his sisters' inventions, causing trouble and mayhem for the town. Just as often, however, Johnny proves himself to be very clever, either by convincing his sisters to help him solve his created problems or by saving the day from whatever good happens to show up. Unfortunately, he always resorts to deceit (sometimes blackmail) to get what he wants and he angrily bemoans when things don't work out to his liking. Johnny's catchphrase is "Whoa, didn't see that coming!" during an unexpected event. Despite being generally repulsed by girls, he has nurtured attraction towards his classmates Janet and Sissy, the latter out of hostile rivalry. As a procrastinator, Johnny goes to great lengths to avoid any work, often using his sisters' inventions to do so, putting himself and others in danger as a result. He also has a superhero alter ego that he calls "Johnny X", whose superpowers include hurricane hands (speeding wind from his hands), shapeshifting, fire-powered transformation, teleportation, ESP, and "Power Poots". A running gag for this form is that his hurricane hands never work, either due to the target being immune to it or other factors.
Dukey
Dukeson Leonard "Dukey" Test (voiced by Louis Chirillo in Season 1–4 and Trevor Devall in Season 5–6 and the revival series) is Johnny's anthropomorphic talking pet dog and only friend. He often serves as the voice of reason whenever Johnny is on the verge of making a destructive or hasty decision. The cause of Dukey's anthropomorphism is the result of one of Susan and Mary's inventions. Dukey will usually behave human-like around Johnny, Mary, and Susan, but will revert to acting like a dog around others, including Hugh and Lila. A running gag involves Dukey accidentally speaking in someone's presence, causing them to question "Did that Dog just talk?" with Johnny, Mary, or Susan answering "No". On the occasions that Dukey has been seen in public, he dresses up in various clothing and passes himself as Johnny's "hairy friend" or "the kid with the rare hair disorder". His superhero name was "Super Pooch", but then changed to "Super Dukey." Super Dukey has all the same power as Johnny X, but usually crashes while flying. His TinyMon name is "Mymuttdog," and he evolves into "Dukandra." In the 2005 pitch pilot, Dukey was originally named "Poochy".
Susan and Mary Test
Susan and Mary Test (also known as The Test Twins) are Johnny's genius twin sisters and daughters of Hugh and Lila, who frequently use him as a lab rat for various inventions, most of which to impress their neighbor, Gil. Though they generally refuse to help Johnny in his antics, they usually end up doing so anyway due to Johnny blackmailing or manipulating them, or in exchange for Johnny allowing them to use him as a test subject. Their hard-headed demeanor makes them gullible, and they have been tricked by Johnny on various occasions. They have a habit of speaking in unison especially when reciting their catchphrase "We're such geniuses". Both twins wear traditional lab coats and harbor a deep love and obsession for the Tests' next-door neighbor, Gil, although their attempts to attract his attention always fail. Both girls attend school at the Porkbelly (formally Mega) Institution of Technology.
Susannah Laura "Susan" Test (voiced by Maryke Hendrikse) is the younger twin. A 13-year-old girl who's the sister of Mary and Johnny and the technical middle child of Hugh and Lila. Susan has navy blue (later cyan blue) eyes, wears black skirt, knee-high socks, a pair of Mary Janes, and a light blue t-shirt depicting a blue star. She has straight red hair, is held with a yellow star-shaped clip, and wears square-shaped glasses. Susan tends to be more irritable and harsh than Mary is, which often leads to her downfall. In the episode "Johnnymon," she claims to lack sympathy for anyone. Eugene/Bling-Bling expresses fond interest in Susan, much to her disinterest. When Bling-Bling pursues Susan, she tries to bribe Johnny into protecting her. Her Catchphrases are "too much?" and "got carried away."
Marionette Louise "Mary" Test (voiced by Brittney Wilson in Seasons 1 & 5, Ashleigh Ball in Seasons 2–4 & 6, Emily Tennant in the revival series) the older twin. A 13-year-old girl who's the sister of Susan and Johnny; and the technical oldest child of Hugh and Lila. She has greenish-blue eyes and often wears baggy blue jeans and green sneakers with her trademark yellow t-shirt depicting light blue half moon. Mary has curly red hair, is held with a light moon-shaped clip, and wears moon-shaped glasses. Mary is more friendly and warm-hearted than Susan. She believes less in science and more in science fiction, which somehow always proves to be correct, despite Susan's scorn. She is also more level-headed and conservative than Susan and speaks her mind much less often.
Secondary characters
Hugh Test
Hugh Test (voiced by Ian James Corlett) is the stay-at-home father and husband of the Test family. Throughout the series, he is portrayed as the disciplinarian of the Test household since, unlike his wife, he has shown to be the one who is more likely to scold and punish his children, mostly Johnny. Hugh has blond hair, blue eyes and wears a green sweater over a yellow shirt with brown pants and loafers. Hugh is (apparently) naive because Dark Vegan can perform a mind trick on him and they only work on dumb people. Hugh's two biggest obsessions are cleaning and cooking meatloaf which the rest of the Test family and anybody else openly despises. He also gets distracted if he loses his shoe and can't focus on anything if he does, something that Johnny occasionally exploits. Hugh often wants his children to come back before dinner at risk of being grounded. A running gag is that he will often ground them for a month for even the smallest offense or for ridiculous reasons, using his annoyed temper. Hugh has forced everyone (including his wife) or trick anyone to get his way such as giving up all her phones due to vacationing reasons. He outlaws genetic experiments by Susan and Mary towards beings (although it's rarely mentioned); despite it being frequently defied. Even with his obsession for the rules, Hugh loves his family. He says that he put rules for the family's security.
Lila Test
Lila Test (née Little) (voiced by Kathleen Barr) is the mother of Johnny, Susan, and Mary and wife of Hugh. She has brownish-reddish hair, green eyes (later cyan blue), and wears a typical women's work suit, pearl necklace, and heels. She is a businesswoman who specializes in telemarketing. Due to the demands of her job and the fact she's a workaholic, Lila isn't seen at home as often as the rest of the family, but her family always comes first and she never misses out on vacations and family events. Lila also possesses martial arts skills, was shown to be strong enough to defeat a towering caveman-themed wrestler, and is shown to be less strict than her husband, but sometimes forced against her will to take a break from work to relax. Lila has a scary/crazy side that even Hugh has shown fear when he makes mistakes in front of her. She is a dedicated perfectionist and will have a mental breakdown when pushed too far.
Gil Nexdor
Gil Nexdor (voiced by Andrew Francis) is a handsome 15-year-old boy and Susan and Mary's crush who doesn't even know they exist, despite having lived next door to him since they were born and even having met them face to face on several occasions. He is continuously depicted as intellectually lacking, although his handsome looks compensate for this most of the time. Much to the great ire of Susan and Mary, Gil considers Johnny his friend (whenever Gil appears when Johnny is around, he shouts "Hey, Johnny!"). Due to Susan and Mary's crush, many of their experiments often revolve around him, on some occasions even affecting him directly. However, he can never seem to remember their names save for occasions. Gil's surname "Nexdor" is a pun on "next door," alluding to the fact that he is Johnny's next-door neighbor and a play on the term "girl next door", of which stock character Gil serves as a genderbent example of. In the first season, Gil was actually halfway competent and a bit intelligent.
Mr. Black and Mr. White
Mr. Black (voiced by Bill Mondy) and Mr. White (voiced by Scott McNeil in the original series and Deven Mack in the revival series) are two secret agents who ask the Tests (Johnny, Mary, Susan, and Dukey) for help whenever they cannot handle a crisis alone which is most of the time. They seem to be highly incompetent and somewhat slackers at their job. Mr. Black and Mr. White claim not to be afraid of anything and could shoot ropes from their wrists in their first appearance. Ironically, Mr. White is Black Canadian and Mr. Black is European Canadian (likely of Germanic ethnic origin). Despite first appearing as villains, they're now friends to the Test kids on most occasions. They also have a hidden passion for cooking. They also dream of a vacation in Fiji and say so in a singsong voice ("we are going to Fiji").
General
The General (voiced by Lee Tockar) is Mr. White and Black's boss and leader of the area 51.1 army base. Loud, slightly incompetent, and forgetful, he frequently takes action whenever the situation becomes too large for the Tests to maintain, although his efforts never fare any better (he even causes the situations sometimes). Even though he doesn't approve of the Test Family and their experiments, He still considers them an ally. The General is prone to overkill and rarely considers what result his actions may have on civilians, to the point he fired at a forest, an inhabited area, and even an amusement park, all in an attempt to destroy a monster. He is also very prone to be a glory hog and gloater when he is successful. The running gags in the series involves the General forgetting something and hesitating to remember and planning to get Johnny, Dukey, Susan and Mary an internship when they graduate.
Sissy Blakley
Elisabeth Olivia "Sissy" Blakley (voiced by Brittney Wilson in Seasons 1 & 5 and Ashleigh Ball in Seasons 2–4 & 6) is a girl who tends to hide her crush on Johnny through bullying and asserting superiority over him. She is 11 (possibly 12) years old around the same age as Johnny. Johnny also has a crush on her, although he doesn't seem to be aware of it or denies it. The two are constantly competing against each other. If Sissy beats him, she will brag about it. Whenever Johnny wins, he'll either get caught into a situation or brag as much as her. Although seen as his equal (if not better than him), Johnny often cheats most episodes. In "Saturday Night's Alright for Johnny" when Johnny pretends to be nice to her, their feelings are shown (along with Dukey and Missy). She seems to be the victim of the show's twists, adventures, and random outcomes; her misfortune often happens at the end of the episode. In later seasons, they become more friendly to each other and Sissy becomes more aware of her crush on Johnny (admitting to thinking he was cute in the 100th episode). She has blonde hair with a red lightning bolt pattern, multiple ear piercings, and a plaid skirt with pants underneath.
Bumper Randalls
Mitchell "Bumper" Randalls (voiced by Scott McNeil) is a local bully who regularly tortures the kids at Porkbelly Jr. High, especially Johnny who he tortures more than anyone else. However, he has a sensitive side as he loves roses and even has a rose garden. He has two cats: a white cat called "Cuddles" and an orange tomcat. In addition, Bumper also has a lizard named Mr. Muncher and a dog. Some episodes imply his father wants him to be a wrestler, but he only wants to grow flowers. So Bumper takes his anger out on Johnny, leading to him bullying all the time. In "Johnny X Strikes Back," he gains the power to turn to stone and flight.
Henry Teacherman
Mr. Henry Joseph Teacherman (voiced by Louis Chirillo in Seasons 1–4, Trevor Devall in Season 5–6 and the revival series) is Johnny's teacher who Johnny believes "has it in for him" (which he sometimes does). He seems to think that his students don't try hard enough and has been shown to like it when a student fails a test (rarely giving assignments on topics they never learn). At times, Mr. Teacherman has even conveyed to get sadistic pleasure out of punishing Johnny. Mr. Teacherman is always very tough, but not always to be mean. He believes that deep down, there is a great student inside of everyone including Johnny. It's shown that even Johnny can't reason, trick, or bribe him out of a challenging assignment or decision showing that he can be super stubborn and strict.
Recurring characters
Janet Nelson Jr.
Janet Nelson Jr. (voiced by Kathleen Barr) is Johnny's former crush. Janet was a self-centered popular girl, that was usually mean and inconsiderate to him, appointing him as a loser. She had a love–hate relationship with him, but she is too popular to express the love part. Janet was a regular recurring character in the first season. By the second season, Sissy Blakely took over as Johnny's main love interest leading Janet to be written off. While Janet would continue to make cameos throughout the second and third seasons. By the fourth season, she had no longer been seen. Janet had long black hair parted in the middle with pink barrettes on the side, and wore a pink shirt, white pants, and purple shoes.
Hank Anchorman
Hank Anchorman (voiced by James Arnold Taylor) is an anchorman for Porkbelly News. In his first appearance, he had blond hair, was thinner and younger. In later episodes, Hank had brown hair (which was a wig), was older, and had a different face. He often reports about the Test family's shenanigans. He is highly devoted to his job to the point he will risk his well-being for a report/update on a story. Hank is also capable of breaking the fourth wall on certain occasions.
Mayor Howard
Mayor Howard (voiced by Lee Tockar) is the Mayor of Porkbelly. He is a short bald man who still lives with his mother. Howard easily panics at the first sign of trouble and will not hesitate to cave in to pressure. Whenever a supervillain appears, he would always agree to swear allegiance with the villain and change the city's name before the villain even says anything. Howard is an unreliable mayor due to his lack of reason, spending on the town, and his constant need for help at even the most simple solvable problems. At one point, Howard exhausted Johnny (as Johnny X) and Dukey (as Super Pooch) due to his constant calling for help, resulting in them "retire" their superhero identities for a while.
Principal Franklin Goode
Principal Franklin Goode (voiced by James Arnold Taylor) is the principal of Johnny's middle school who likes Johnny despite his antics which have caused large-scale destruction on more than one occasion. He always cuts Johnny slack for his antics and even denies Henry Teacherman's constant pleas of punishment for Johnny. However, if he does bail him out, Johnny must fulfill his end of the deal or he'll reverse the decision (which he rarely does because he always gives Johnny another chance). There are times when both Johnny and Henry have both gotten on Principal Goode's bad side, leading him to have no choice but to punish them much to their dismay.
Lunch Lady
The unnamed lunch lady (voiced by Kathleen Barr) at Porkbelly Middle School has greenish skin and speaks in a German accent. She can be very cruel when students don't eat her disgusting (albeit sometimes healthy) food. The lunch lady even becomes a nemesis to Johnny in an episode where she tries to destroy him for giving kids applesauce. She is very stubborn and will go to great lengths to make sure her food is eaten. She can also be a critic as she criticized and even laughed at Johnny's cause for applesauce even though she aggressively pushed her food onto the students and angrily denied anyone who requested anything else other than her food.
Professor Slopsink
Professor Slopsink (voiced by Richard Newman) is the German head professor at the Mega (later Porkbelly) Institute of Technology (M.I.T., later P.I.T). He is also Bling-Bling, the Test twins, and Tim Burnout's Teacher. Due to a mishap with one of Eugene's (Bling-Bling Boy) theses, Professor Slopsink lacks a left hand, so now he uses a robotic hand (though Repto-slicer ate that as well). He sometimes mistakenly doubts or underestimates his students' potential; which results in him being proven wrong, which he responds by giving them a high grade.
Mrs. Hamilton
Mrs. Hamilton (voiced by Lee Tockar) is the mother of Bling-Bling Boy and Mr. Hamilton's Wife. She is very harsh with her son and is always screaming, but is calmed by smooth talk.
Tim Burnout
Timothy "Tim" Burnout (voiced by Louis Chirillo in Seasons 1–4, Trevor Devall in Seasons 5–6) is a classmate of Susan and Mary and the former owner of Mr. Mittens. He copied the modified genetic structure used by Susan and Mary to enhance Dukey and used it on Mr. Mittens which turned him into an evil villain seeking world domination. Despite his lazy personality, Tim is apparently very intelligent as he was able to alter Mr. Mittens (despite stealing the idea). His last name refers to the way he acts.
Lolo
Lolo (voiced by Ashleigh Ball) is Susan and Mary's midnight blue lab monkey on who they sometimes test their experiments. She loves bananas and is somewhat intelligent (possibly due to the sister's tests). Lolo has a strange metal hat piece on her head for an unexplained reason.
Missy
Missy Blakley (voiced by Ashleigh Ball in Seasons 2 onwards; Brittney Wilson in Season 5) is Sissy Blakley's pink labradoodle dog who seems to show the same amount of dislike to Dukey as Sissy does to Johnny. Dukey has a crush on her, but often displays the same hatred Johnny does for Sissy.
Repto-Slicer
Repto-Slicer (vocal effects provided by Andrew Francis) is a blue-green mutant lizard. He earned his name from his ability to have razors protrude from his entire body where he even has a chainsaw for a tongue. Repto-Slicer excels at salsa-making. He was originally owned and created by Eugene, who managed him very poorly. Repto-Slicer later decided to stay with Johnny after he tamed him. In a later episode, Repto-Slicer was transferred to Planet Razorium where he lives happily with alien creatures that look like him.
Jillian Vegan
Jillian Vegan (voiced by Maryke Hendrikse) is an alien from the planet Vegandon who is Dark Vegan's daughter. She disapproves of her father's evil ways and makes friends with Johnny by helping him save his world twice. As of the fourth season, Jillian lives comfortably on Earth, having integrated successfully into its culture. She is a human-shape alien with green hair.
Mrs. Vegan
Mrs. Vegan (voiced by Ashleigh Ball) is an alien from the planet Vegandon who is Dark Vegan's wife and Jillian's mother. Mrs. Vegan constantly nags about her husband's plans to take over the world.
The Turbo Toy Force
The Turbo Toy Force is a group of toys that were animated and given superpowers by Johnny, Dukey, Mary, and Susan to battle Nasteria. The group consists of Stacy, Nice Sweatered Ben, a toy bunny rabbit, a toy dragon, a chew toy, and formerly Mega Roboticle.
Speed McCool
Speed McCool (voiced by Lee Tockar) is a famous actor. In the movies he is in, he has a chimpanzee. Johnny is a fan of his and once used a virtual reality machine to get inside his films.
Montague
Montague (voiced by Lee Tockar) is an anarchist-talking mouse bent on world domination. He is a wild card, but will succumb to cheese. He appears in two episodes: in Johnny's Big Dumb Sisters, he makes brief cameos, but in Tom and Johnny, he has a more significant role, eventually helping out the Test siblings and Dukey. Montague becomes an antagonist in one episode where he tries to live in Johnny's house.
Dog Catcher
The unnamed Dog Catcher (voiced by James Arnold Taylor) is the owner of Porkbelly's Animal Control. His first appearance was in the episode "Here Johnny, Here Boy!" where he captured Johnny, Susan, and Mary after using the Animal Machine which turned them into animals (Johnny into a dog and Susan and Mary into lions). The Dog Catcher made minor appearances such as "Johnny's 100th Episode" where we see that Johnny first adopted Dukey.
Fillmore
Fillmore (voiced by Lee Tockar) is a clerk in the video game store "Game Galaxy." He made his first appearance in the episode "Phat Johnny." Johnny once made teased of him because he's fat (although Fillmore claims he has a glandular problem).
Villains
Bling Bling Boy
Eugene "Bling-Bling Boy" Hamilton (voiced by Lee Tockar) is a prominent antagonist of the series and frenemy of Johnny and Dukey, preferring to be called "Bling-Bling Boy" (because of his gold jewelry and watches). However, most characters usually address him by his real name, which annoys him greatly. He is a multi-millionaire with unlimited funds at his disposal. Bling-Bling Boy is also somewhat powerful among the characters despite having fears of being punished by his mother. He has a big crush on Susan, who doesn't reciprocate his feelings, and often resorts to evil plots or blackmail to win her affection, which always fails, usually courtesy of Johnny. Bling-Bling Boy occasionally teams up with Johnny and Dukey to defeat the other villains when the situation demands it. Similar to Susan and Mary, he often tricks Johnny into testing some of his inventions. Deep down: Bling-Bling Boy is insecure due to being obese and having buck teeth, although in "Phat Johnny," his weight and buck teeth help him become successful as a hip hop star. Bling-Bling Boy also attended the Mega Institution of Technology, but was kicked out after his thesis ate Professor Slopsink's hand. He later was allowed to return to the Institute in exchange for aiding in preventing a nuclear crisis. In "Johnny X Strikes Back," Bling-Bling Boy gains the power of gold vision and flight. In the 2005 pitch pilot, he was originally named "Golden Boy" and appeared to be designed much younger.
Miss X and Miss Z
Miss X and Miss Z (voiced by Brittney Wilson in Season 1, Maryke Hendrikse in Season 2) are two cyborgs created by Bling-Bling Boy to work at their disposal. They can operate and have a mind of their own when Bling-Bling is not around or in need. Miss X and Miss Z have high intelligence, capable of studying at the Institute Of Porkbelly, and avoid attention. Throughout the seasons, they are more robotic and shown to have more than one pair of them. Miss X and Miss Z only appeared in the first two seasons of the show.
Wacko
Wacko (voiced by Colin Murdock) is one of the first major villains of Johnny Test. Despite being a toymaker and the head of the toy company Wacko Toys, he deeply loathes kids and makes incredibly destructive toys to rid the world of them. He seems quite intelligent and quite wealthy despite the bad publicity he brings to his company. Wacko would come up with plans to get rid of kids which often annoys his employees who constantly remain loyal to him. He is the leader of the Johnny Stopping Evil Force 5 where he formed its first incarnation with Brain Freezer, Beekeeper, Mr. Mittens, and Mr. Mittens' butler Albert with King Zizrar being part of the second incarnation when Beekeeper turns good. Wacko is obsessed with destroying Johnny and the Tests at almost every chance he gets, due to Johnny foiling his plans in the past, making him go mentally insane. He is so obsessed with Johnny, he'll carelessly risk his own safety or other people just to gain an advantage over The Tests. Wacko is later revealed to have a twin brother named the Tickler.
He is somewhat similar to Toyman and his name is a spoof of Wham-O, a real-life toy company, and Wacko, fittingly, means "a crazy person."
Brain Freezer
Brain Freezer (voiced by Louis Chirillo in seasons 1–4, Bill Mondy in seasons 5 & 6) is the former janitor and coffee guy of P.I.T. He is a self-proclaimed genius with his inventions typically involving both coffee and ice. Brain Freezer has a "Chillachino Machine" that can freeze anything including creating armor made of ice. It appears that Brain Freezer is immune to the blasts from his freeze gun as he uses them to transform into his supervillain form by blasting himself, but his "Chillachino" will still freeze him solid if he drinks it. He often makes ice-related puns. In one episode, the reason for Brain Freezer's villainy is that he's just lonely and that girls constantly reject him (which he responds with insanity/madness and hatred) leading his character to be a sympathetic villain.
The Beekeeper (voiced by James Arnold Taylor) is a man in a beekeeper's suit that can control bees. His secret identity is Doc Beebles, maker of Piles 'O Honey Bars. His debut plot was to use his bees to eat all other candy in the world so his Piles 'O Honey Bars would finally sell (nobody bought his bars because they were naturally sweet and healthy), though Doc really wanted the kids to be healthier. After his first defeat, Beekeeper joined the Johnny Stopping Evil Force 5. He does later help out the Test siblings and Dukey saves a candy holiday that they created. Due to this, Beekeeper is currently reformed and likes the Tests leading him to be replaced by King Zizrar on the Johnny Stopping Evil Force 5. Beekeeper loves saying "bee" as "be" as a pun when he's wearing his beekeeper suit.
Mr. Mittens
Mr. Mittens (voiced by James Arnold Taylor) is an evil cat who was enhanced with the same modified genetic structure as Dukey by his owner Tim Burnout. It was mentioned that Tim was a terrible owner to Mr. Mittens due to the fact that Tim never cleans out his litter box. He very commonly tries to turn the entire world into cats in his evil plans like he did in his first appearance or he plans to have revenge on Johnny and Dukey. In one episode, Mr. Mittens claims to want revenge on Johnny when in reality, he's just lonely like Brain Freezer. Like Dukey, he is highly intelligent but seems to lack Dukey's fighting skills and luck. Mr. Mittens also loves to cheat in competitions which usually backfires with instant karma. A running gag of his is that he coughs up hairballs at specific moments.
Albert
Albert (voiced by Lee Tockar) is Mr. Mittens' aforementioned butler who used to serve Mr. Mittens' owner Tim Burnout. Albert isn't seen hating Johnny, but he was forced into the squad because he has to take care of Mr. Mittens all the time (it is debated if he's a villain or he's just doing his job). He is quite calm and down to earth. Albert has shown that he can't be tickled, even by the best machines (in fact, he broke and overloaded a machine in the process of being tickled) at the time when Johnny Test faced off against Wacko's twin brother the Tickler. He has also shown to have matching intelligence as his master. A running gag is that when Mr. Mittens coughs up hairballs at specific moments, Albert would clean it up.
King Zizrar (voiced by Scott McNeil) is the ruler of the mole people who on a few occasions attempted to take over the world or invade the surface only to fail due to his intense aversion to light. He's charismatic and a good tactician, but can be a pushover at times and a coward when the odds don't work in his favor. King Zizrar is the first villain Johnny ever fought, though is among the least-recurring villains. After the Beekeeper reformed from the Johnny-Stopping Evil Force Five, King Zizrar took his place. While earliers King Zizrar was very small and short in season 1, being about half Johnny's size, later seasons had him much bigger and taller, being roughly the same height as Johnny.
Dark Vegan
Dark Vegan (voiced by James Arnold Taylor) is the alien ruler of Vegandon, a seemingly utopian planet composed completely of the Vegans, humanoids who at first appear peaceful and well-meaning, but in reality, they go to other planets and sap them of their resources which is what he tried to do to Earth on two occasions and nearly succeeded.
After his second attack on Earth, he and his family were left stranded on Earth, much to the ire of Vegan and the pleasure of his family. Although Johnny eventually helped him to return to Vegandon, he later returned to Earth and became a regular resident after discovering his planet was incapable of producing his new favorite food: toast.
Dark Vegan has a mind-control power that works only on dumb people. He is Jillian's father and is very overprotective of her (he threatens the Earth/Johnny with destruction if his daughter isn't satisfied or if it doesn't meet his standards). Later in the series, Dark Vegan appears as a wildcard of The Tests (he constantly changes from ally to enemy, especially to Johnny).
He is a composite parody of Darth Vader from Star Wars and Dark Helmet from Spaceballs due to having the latter's retractable face covering on his helmet and the formers voice-deepening effect.
Minor villains
The following are minor villains that Johnny went up against:
The Caveman: Appeared in the episode "Stinkin Johnny", the Caveman is a towering caveman-themed wrestler. Johnny wants to enter a wrestling competition so that he can win a new HDTV. Before wrestling, Susan and Mary make a costume for Johnny which allows him to spray gas out of his costume. Before Johnny beats The Caveman at the competition, Johnny sprays gas at Bumper, three evil dogs, and his dad. First, The Caveman defeated a wrestler named Brack-Breaker when he threw him out of the cage defeated. When Johnny was about to spray The Caveman with his costume, he realized that he ran out of perfume after spending it on the wrestlers in line and gets chased by The Caveman. Johnny gets kidnapped by the Caveman, and Dukey, Susan, and Mary try to rescue Johnny but they get kicked out. Johnny's dad shows up but he gets thrown out as well. When Johnny was about to be beaten up by the Caveman, his mom appears to save him. After Lila beats the Caveman, she saves Johnny and wins $10,000. In the end, Johnny and Dukey both get grounded from TV, and Susan and Mary both get grounded from the lab.
Blast Ketchup (voiced by Kathleen Barr): The main character of the Tiny'Mon games, Blast Ketchup has dreams of becoming the World's Greatest Tiny'Mon Master. Ever since Johnny was trapped in their world and Blast was defeated by Johnny, it became his goal to defeat Johnny in Tiny'Mon to become the Tiny'Mon champion he self-proclaims deserves. It is easy for him to detect tricks and is not under using dirty tactics to win such as kidnapping. He always takes the first words of what people say, mistaking them as Tiny'Mon. He is a parody of Ash Ketchum from the Pokémon series.
Ed: Blast Ketchup's friend and cheerleader. He's always considered everyone as a loser, despite showing a lack of social skills and experience in Tiny'Mon.
Screechereen: Evolved from the almost completely-weak Cuddlebuns. She is a legendary Tiny'mon that many believed didn't exist and is incredibly strong. In Return of Johnny'mon, she is brought up as female. She resembles Lugia from the Pokémon series.
Cuddlebuns: A cute but weak Tiny'mon. In fact, it is the weakest Tiny'mon ever. In Johnny'mon, it is revealed that it can evolve into Screechereen when given love.
Baboomerang and Badias: Blast Ketchup's Tiny'Mons. Baboomerang (formerly Kadoomerang) is listed with 1000 Power Point's, while Badias has 1100. Baboomerang appeared as an anthropomorphic baboon. He wore armor, a belt, and a diaper. Badias appeared like Screechereen but in black.
Claire Nefarius (voiced by Kathleen Barr): A character who appeared in the episode "The Quantum of Johnny". She is the daughter of Larius Nefarius. In the episode, she had a birthday party and hid to launch missiles into her father's factory (which was nearby) to get her dad to spend more time with her. Johnny constantly mentions that she is hot. At the end of the episode, Larius Nefarius learned of his mistake and promised to spend more time with her and act like a father. He started by forbidding her from dating Johnny because she is too young.
Warty (voiced by James Arnold Taylor): Johnny's talking wart who appeared in the episode "Johnny's Got a Wart!". He started as a regular wart until he was brought to life. Although Johnny was unsure how he obtained a wart on his left wrist. Worried, Dukey took him to the Lab, hoping Susan and Mary get rid of it. They shot it with a "laser", though it failed. Later at school, the wart came to life and became helpful to Johnny: he helped him remember his locker combination, got him an "A" in math, confronted Bumper by revealing his inner soft side, and got Johnny an invite to a party with cheerleaders. After school, Warty grew eyes that Johnny thought was creepy.
