Test Family
Johnny Test
Jonathan Xavier "Johnny" Test
"Woah! Didn't see that coming."
Voiced by: James Arnold Taylor
The show's protagonist and youngest member of the Test family. Johnny creates many of the show's plots through his willingness to abuse his sister's inventions or cut some corner in life. His best friend is Dukey, his (talking) dog. Occasionally Johnny fights crime using superpowers gained from his sisters under the name Johnny X.
- Aesop Amnesia: Johnny learns lessons. He just never remembers those lessons.
- Ambiguously Bi: Johnny does display interest in girls including Sissy and Jillian Vegan but he gets into
questionable moments with both Dukey and Gil. While it can be argued that Johnny loves Dukey in the same way that a typical boy loves his dog, Johnny's interactions with Gil are somewhat chummy as Johnny is not repulsed at all by Gil's comments towards him and he even accepted Gil's offer to go on a date with him, which involved a candlelit dinner. - Annoying Younger Sibling: And apparently, he's holding back. He once got his sisters to agree to do something by threatening to somehow be 100 times more annoying… It worked!
- Attractive Bent-Gender: Whenever he dresses like a girl. He briefly turned into a beautiful teenage girl during the pilot after using 'Mega Hottie Body Flakes'.
- Blackmail: In the early seasons, around how Johnny convinces his sisters for a favor, the blackmail usually being 'unapproved' experiments.
- Blah, Blah, Blah: What Johnny always says whenever Susan and Mary try to tell him how their invention works or warn him about overusing it.
- Book Dumb: Clever and manipulative, but a poor academic performer.
- Bratty Half-Pint: Sometimes, Johnny just can't take "no" for an answer, leading him to use Puppy-Dog Eyes and blackmail to manipulate his parents, dog, sisters, and authority figures.
- Brilliant, but Lazy: He only seems stupid; he's just too dang lazy to apply it to school or much else. However, if it's something that has to be done or he really wants to do, he can come up with plans even his sisters find downright amazing. Basically, it's surmised that while his sisters got all the smarts, he got all of the creativity.
- Butt-Monkey: Not that he doesn't bring a lot of his downfalls onto himself, but many episodes revolve around making Johnny suffer some sort of fatal predicament and make sure things don't end in his favor.
- Can't Get Away with Nuthin': If Johnny uses some advantage for personal benefit, it will almost certainly backfire on him by the end of the episode. In a few instances, he has to use the advantage for the greater good, costing him his benefit. A good example is where he obtained x-ray vision to win at a game show, the prize being enough money to be set for life. Before he can actually select the suitcase and get the money, Dukey convinces him to go and save the library from being taken by the mole people.
- Catchphrase:
- "Whoa, didn't see that coming!"
- "Say, wha-?"
- "You don't love me!"
- "Now where have I seen this before?"
- Character Title: The show's title refers to him.
- Cosmic Plaything: More or less. A majority of the plots center around many obstacles getting in the way of Johnny's goals and ruthlessly tormenting him. How terrible his day is depends on the writer.
- Cross Dresser: Johnny does not like having to do this often as a result of either his sister's experiments on him or missions that Mr. Black and Mr. White puts him on.
- Crouching Moron, Hidden Badass: The kid's got a dunce streak in him. But he always saves the day.
- Deadpan Snarker: He can deliver witty, snarky lines every now and then.
- Dumb Blonde: He's Book Dumb and blond.
- Girls Have Cooties: Zig-zagged depending on the episode. Sometimes he shows interest in girls, while in one episode he's disgusted to have been kissed by a girl.
- Ham-to-Ham Combat: Against many of his villains, particularly Bling-Bling Boy.
- The Hero:
- He is declared The Chosen One in one episode, where he helps a pair of "Ribeye Knights" save their planet with nothing to gain for himself.
- He has also been called in by the government numerous times to help with any problems currently in need of fixing.
- Identical Stranger: Johnny looks exactly like Princess Mirabelle, so the SSGA gets him to take her place when the princess goes missing.
- Idiot Hero: In general, the mayhem caused in a good number of episodes could have been avoided entirely if Johnny hadn't tried using the girls' science to get out of chores, school, or anything else involving effort. Justified though in that he's only 11.
- It's All About Me: On some occasions, he can tend to be a bit selfish.
- Jerk with a Heart of Gold: Despite being an Unsympathetic Comedy Protagonist, he's a kid who still has a lot of growing up to do. He does deep down love his family and tries to be genuinely helpful occasionally. He's also the one who always saves the day even if he has nothing to gain.
- KidAnova: He had a few girls crush over him.
- Kid Hero: He saves the day from supervillains, invaders, and sometimes, his own mistakes.
- Large Ham: Johnny can get pretty dramatic and raise his excitable emotions to the roof.
- Laser-Guided Karma: Usually Johnny's immoral actions will come back to bite him in the ass.
- Manipulative Bastard: Johnny knows how to grift his parents and sisters to get his way.
- My Sister Is Off-Limits: Played With. While Johnny usually helps Susan avoid Bling-Bling Boy's affections to have her do his homework, he too is also disgusted by the idea of her going out with someone like him.
- Narcissist: He's a very self-centered individual.
- Nice Job Breaking It, Hero: Many of the episodes' main threat is his fault in some way. Though in his defense, he always tries to fix it in the end.
- No Indoor Voice: He doesn't have an indoor voice, especially in the house. He frequently yells.
- Playing with Fire: His signature power is his 'Flaming Power Poots'. He was also given the ability to engulf himself in flames to defeat the Brain Freezer in one episode.
- Puppy-Dog Eyes: Sometimes Johnny will use puppy dog eyes to manipulate others.
- Small Name, Big Ego: He thinks he's so cool. But to be fair, he has many accomplishments under his belt. Though he can't always walk his talk.
- The Slacker: Johnny hates hard work and would rather lie, cheat and use his sisters' experimental and often highly dangerous science than actually do the work. This will often lead to him doing more work when he fixes his mistakes.
- Spoiled Brat: Subverted. While he has to resort to blackmail or begging to get what he wants from his sisters, they more or less often experiment on him as frequently and could be seen as a form of 'payment.' However, he does play this straight by being quite selfish and bratty.
- Unsympathetic Comedy Protagonist: It can be hard to root for him in some episodes. He can be selfish, rude, and disrespectful. But this is mostly towards the people in his family. He behaves kindly enough towards friends and strangers for the most part. And even then if his family is in danger, he'll usually come to their aid in a heartbeat.
- Vocal Evolution: His voice was deeper in season one, but season two onwards gives him more of a falsetto voice.
- Voice Change Surprise: One episode ends with him, in the aftermath of the episode hijinks, replying to a question from his parents by saying "Woof, woof" and then covering his mouth in surprise. Cue Dukey talking fluidly.
- Weaponized Stench: In "Stinkin' Johnny", Johnny enters a wrestling contest to win prize money. His main attack is a foul smell that he obtains after spraying himself with a perfume created by the girls that don't smell as intended.
Dukey
Dukeson Leonard "Dukey" Test
"I'm a kid with a rare hair disorder".
Voiced by: Louis Chirillo (season 1-4), Trevor Devall (season 5 onward, including revival series)
Johnny's talking dog who was genetically enhanced by Susan and Mary some time before the series. Dukey's main job is to act as Johnny's voice of reason even if he's prone to being ignored. That said, he's more than capable of doing the wrong thing himself if properly motivated (such as with steaks). On more than one occasion he acts as a crimefighter alongside Johnny under the monikers Super Pooch, X Pooch or Super Dukey, though after the earliest incidents he expresses a dislike for doing so.- Action Pet: He is a black-belt in Kung-Fu.
- Berserk Button: Harming, trying to kill and/or being responsible for Johnny's mortality in front of Dukey.
- Big Friendly Dog: Nearly Johnny's size, and has a sweet nature.
- Brought to You by the Letter "S": On his Super Pooch costume, although the letter is D which appears nowhere in his Super Pooch name.
- The letter in this case is a holdover from when his alter ego was called "Super Dukey". The writers have since flip-flopped on exactly what his superhero handle is between "Super Dukey", "Super Pooch" and "X Pooch".
- Butt-Monkey: Gets lots of bodily harm.
- Catchphrase: "I'm a kid with a rare hair disorder".
- The Chew Toy: Dukey often suffers a lot of injuries as a result of Johnny's shenanigans. One such example was when Johnny tried to break a record and win money by participating in a stunt created by an eccentric billionaire, Dukey tried to stop Johnny from doing the stunt but ended up doing the stunt himself by accident, which resulted in him getting injured and put in a full body cast.
- Cowardly Lion: Dukey will never miss an opportunity to complain and cower, but he comes through in the end.
- Deadpan Snarker: When you hang around with a troublemaker like Johnny, it comes naturally.
- The Drag-Along: Most of the time unless the situation calls for it.
- Funny Animal: An anthropomorphic dog, with emphasis on "funny".
- Fun T-Shirt: In the earlier seasons, he sometimes wears a T-shirt with "Not A Dog" written on it when he pretends to be a human with a hair disorder.
- Gasshole: And he's not too shy about it either...
- Hypercompetent Sidekick: Borderline Beleaguered Assistant. However, his reason of doing matters is only out of being forced to go or Johnny's safety, being Brilliant, but Lazy
- Intellectual Animal: Thanks to Susan and Mary's experimentation, Dukey is every bit as smart as a human and even sometimes more sensible than a lot of the human characters.
- Large Ham: While he usually tries to present himself as more down-to-earth, Dukey does enjoy hamming it up from time to time. Most often when there's an incentive or when he can't help but get engrossed in Johnny's over-the-top shenanigans.
- Mans Best Friend: Or should we say Boy's Best Friend. Johnny is his human companion.
- Martial Pacifist: Susan and Mary included the DNA of Kung Fu masters in his genetic code, making him a skilled martial artist...however, he doesn't like using it and more often would just prefer to stay at home and goof off than fight supervillains. He also refuses to teach it to Johnny since he knows Johnny doesn't have enough self control not to use it.
- Master of Disguise: Works due to most people in their world being stupid. He normally just says he's a 'kid with a rare hair disorder' and they believe him. He also sometimes wears a t-shirt that says "Not A Dog". Or, when he's trying to pass himself as a regular dog, he'll just say the word "woof" instead of actually barking.
- Morality Pet: Played with in the fact that although he tried to convince Johnny something is wrong (or right) to do, he often fails at changing Johnny's mind unless it has to do with his family. Also tries to convince the Sisters that treating Johnny like a guinea pig is wrong. Fails in that as well.
- Only Sane Man: Though almost anyone looks sane next to Johnny. Dukey is probably the most believable voice of reason in this show.
- Phrase Catcher: More so in the earlier seasons; a Running Gag was that people would refer to him as "the/that ugly dog" or some variation there of, usually prompting him to retort, "I'm not that ugly!"
- Plot Allergy: In "Lil Johnny", Dukey starts sneezing constantly after he and Johnny get shrunk. Dukey says that he is sneezing because of his allergies but never states what he is allergic to. However, several dust mites appear on screen to attack Johnny and Dukey moments after Dukey states that he is allergic, which implies that Dukey is allergic to either dust or dust mites.
- Screams Like a Little Girl: When he's scared.
- Shrinking Violet: Shy, has feminine mannerisms, and a nice dog.
- Sleep Mask: Dukey sometimes wears a pink one in his sleep despite being a dog. Its most prominent in " Green Johnny"
- Trademark Favorite Food:
- Dukey would do anything for a steak. Or bacon.
- Also enjoys coffee.
- Undying Loyalty: He may have doubts about Johnny's schemes but he is his loyal dog.
- Uplifted Animal: He was originally a (comparatively) normal mutt before Susan and Mary gave him the abilities of a human.
Susan and Mary Test
Susannah Felicity "Susan" Test and Mary Louise Test
"We're such geniuses."
Susan voiced by: Marÿke Hendrikse
Mary voiced by: Brittney Wilson (season 1, 5); Ashleigh Ball (season 2-4, 6); Emily Tennant (revival series)
Johnny's older twin sisters who attend the Mega Institute of Technology. Both are geniuses capable of devising whatever machine the plot demands and most episodes relate at least partially to one of their experiments. Both Susan and Mary have a crush on local boy Gil that can work against them. Susan is also the object of affection of resident villain Bling-Bling Boy. Both sisters look identical except for their fashion choices (Susan wears squared glasses, a skirt and knee socks and has straight hair; Mary has curved lenses, wears jeans and has curled hair).- Abhorrent Admirer: To Gil, even though the guy is so oblivious to their advances that he cannot even remember their names.
- A-Team Firing: Once. Mary attempted to hit a transformed Dukey with the needle containing a serum that will turn him back to normal and every shot hits somewhere on the wall around him.Mary: Man I am a lousy shot.
- Agent Mulder and Agent Scully: Mary and Susan, respectively; they even have the same first letter initial.
- Balloon Belly: Not as often as Johnny or Dukey, but they will gorge themselves on occasion. One time they fattened themselves up with candy, and another they got bloated from eating too much ice cream.
- Butt-Monkey: Susan has a lot of slapstick.
- Captain Ersatz: They look pretty much like a pair of older female Dexters.
- Catchphrase:
- "We're such geniuses." Well, in the first seasons anyway.
- And "*sighs* Gil, next door".
- Clingy Jealous Girl: They tried to take out Jillian Vegan when Gil has a crush on her.
- Cut Lex Luthor a Check: A non-evil example. The only reason they bother inventing things is to get Gil to notice them. When he says that he's moving away, they immediately shut down the lab forever, and Johnny takes it upon himself to try and stop Gil from moving.
- Dogged Nice Guy: They try their best to win Gil's affections though he doesn't seem to notice them. Admittedly, they do go to some creepy lengths.
- Failure Is the Only Option: Their attempts to attract Gil attention always end in failure.
- Fiery Redhead: Susan tends to be more irritable than Mary is, which often leads to her downfall.
- Love Makes You Crazy: Their attempts to get Gil to notice them always backfires or screws up. Not to mention fighting one another over who will marry Gil, ending up with them becoming a couple of messes, which derives Gil's attention to Johnny.
- Magic Skirt: No matter what she does, Susan's skirt doesn't seem to ever move. Not even if she's sliding, falling, or doing cartwheels.
- Nice Job Breaking It, Hero: They end up causing the disaster-of-the-week as often as Johnny, and more often than not end up needing Johnny's help to fix it.
- Our Vampires Are Different: When the twins turn themselves into vampires in "Fangs a Lot Johnny", they wear black gothic dresses, their eyes turn a cat-like green, and, in Mary's words, "Hip teen vampires glitter in the sun now". This counts as a Take That! towards the Twilight Saga, as the episode was based on it.
- Red Oni, Blue Oni: It's subtle but it's there. Susan is the red: more rational minded, always tries to see if there's logical explanation for everything and can be rather stubborn. Mary is the blue, willing to believe more in the unnatural and is usually the voice of reason between the pair. Ironically, Susan wears a blue shirt while Mary wears a yellow one. There's also a dash of Tomboy and Girly Girl with their way of dress (Susan wearing a skirt and Mary Janes while Mary wears jeans and sneakers).
- Single-Target Sexuality: They are only interested in Gil even though he's a Dumb Blonde who clearly has no interest in them or even awareness that they exist, no matter how hard they try to get his attention. Zizrar at one point questions what do they even see in him.
- Smitten Teenage Girl: They both have a crush on Gil.
- Stalker with a Crush: To Gil. They pull off often very disturbing lengths to go out on a date with him.
- Sweet Tooth: One episode showed they have a stash of sugary junk food hidden in their lab.
- Teen Genius: 13-year-old brainiacs who have all the science smarts.
- Theme Twin Naming: Averted because their names are Susan and Mary, which don't rhyme and are not thematic
- Twin Threesome Fantasy: Somewhat averted Depending on the Writer. Sometimes the twins are shown to be open at the idea of sharing Gil, but there are episodes when they fight each other to be the only girl he has eyes for. Marriage seems to be the touchiest point; dating and making out not so much.
Hugh Test
Hubert "Hugh" Test
"Meatloaf!"
Voiced by: Ian James Corlett
He is the patriarch of the Test household and the father of Johnny, Susan, and Mary Test. He is a stay at home dad who does all the housework and is known for declaring that his kids be home on time or else they are grounded. He obsessively loves to cook meatloaf for dinner, which the rest of the Test family hates.
- Abusive Parent: Several episodes have him stating what kind of punishment he plans to give Johnny, many of which are rather cruel for the smallest of reasons. Its generally Played for Laughs.
- Deadpan Snarker: Often shows shades of this on occasion.
- Depending on the Writer: Some episodes he can tend to be a strict but reasonable parent. But others tends to blur the line in how he parents Johnny and his punishments for his actions.
- Fantasy-Forbidding Father: There are many experiments and hi-jinks he forbids his children from doing. He nearly grounds them all after Johnny shows his parents that Dukey can talk in one episode (Hugh explicitly told them to never experiment on the dog). While they do warm up on Dukey, a jealous Johnny made them forget the whole thing.
- Honor Before Reason: This combined with Skewed Priorities makes up most of his more unreasonable behavior. The best example is "Johnny Get Yer Gum" where he wants to ground Johnny for two weeks because he chewed gum even though it was to save kids from a deadly trap.
- House Husband: He is literally a "house husband".
- Jerkass Has a Point: Sure he's stricter on Johnny than he is on Susan and Mary, but given the amount of havoc Johnny causes on a daily basis it's easy to see why he's so strict.
- Jerk with a Heart of Gold: For all his faults, and the fact he tends to punish Johnny quite severely, more than often a lot of his behavior is a case of Cruel to Be Kind. Plus, half the time his kids do tend to get in over their heads with their shenanigans.
- Large Ham: Courtesy of Ian James Corlett.
- Lethal Chef: By how much is by Rule of Funny. He is capable of making good food, but he loves making meatloaves and somewhat treats it like an art form though that doesn't mean the meatloaf will be tasty (least to anyone but him). In one episode, he attempts to make healthy cookies and Johnny taste it. Johnny replies it tastes like dirt. He then has Johnny eat dirt as a comparison. Johnny then apologizes... citing that dirt tastes better.
- Like Father, Like Son: As much as he would like to think it's his super genius daughters that take after him, it's Johnny that shares the most in common with his dad. Johnny is able to cook (he took home EC for an easy A), he inherited his dad's knack for cleaning (which translated into brush skills in curling) and as much as Hugh would hate to confess, Johnny's love of video games comes from him.
- Neat Freak: Hugh is shown to hate germs a lot and likes the house to be extremely clean. One of the heroes he idolizes inspired him to be this. The theme song of this show even directly quotes him as this trope
- Papa Wolf: Despite having effeminate hobbies, Hugh still maintains a solid iron grip on being the man of the house and does love his children.
- Real Men Wear Pink: Hugh is the man of the house and runs the Test household in a very strict manner but he likes to do chores that are typically that of a housewife's.
- Skewed Priorities:
- In "Johnny's Extreme Game Controller", he is more concerned about his meat loaf burning than Susan cutting her leg or a rabid Lolo attacking his daughters with a spoon, despite actually falling for their lies.
- In an episode where Johnny breaks his foot, Hugh is more concerned about the family's insurance premiums going up.
- The Scrooge: An interesting example of this despite not being the breadwinner of the family and lacking the usual reason a dad would have for this.
- Trademark Favorite Food: Meatloaf. Hugh rarely ever cooks anything but meatloaf, and will go to great lengths to not cook anything else but meatloaf. He clearly chooses to ignore the glaringly obvious fact that no one but him likes it, even when his family wretch with horror at the sight of it and Johnny openly states no one else likes it.
- You Are Grounded!: He threatens to ground his kids for life constantly even though in one episode, Susan and Mary state that he can't ground children when they are 18, which makes him change his threat to grounding them until they turn 18.
Lila Test
Lila Test (née Little)
Lila Test
Voiced by: Kathleen Barr
She is the mother of Johnny, Susan, and Mary Test. She is a strict businesswoman who makes the money for the Test household. She, like the other Test family members openly despises Hugh's meatloaf obsession.
- Action Mom: If push comes to shove, she'll be willing to jump into the fray if she must.
- Lethal Chef: She is shown to have worse cooking skills than her husband.
- Mama Bear: She wouldn't let anyone hurt her kids, that goes for Johnny, the Girls and Dukey.
- Workaholic: She is obsessed with her job. The theme song even describes her as a "super busy mom".
Recurring characters
Gil Nexdor
Gil Nexdor
Voiced by: Andrew Francis
A pleasant local boy who's friends with Johnny. He's the romantic target of both Susan and Mary, though he can never seem to remember their names.- Ambiguously Bi: Shown to clearly crush on girls, but seems oddly fixated on Johnny over his twin sisters. He's even infatuated with Speed McCool, so much he agrees to a picnic with him.
- Beware the Nice Ones: When Gil's life is threatened by the boy robots created by Susan and Mary, the Test siblings put him in a metal box, and once he's out, he takes back Susan and Mary's invitation to his pool party.
- Brainless Beauty: The boys head is hollow as a coconut, despite his preference for wearing a helmet (a.k.a. Brain Bucket) when he goes skiing.
- Catchphrase: "Hey, Johnny!", or "Tell Johnny I said hi!" whenever Johnny's not around.
- The Ditz: He's not very bright as he often forgets people such as Susan and Mary. Its revealed that he acts this way because Susan and Mary have frequently erased his memory, damaging his brain in the process.
- Dumb Blonde: Even more than Johnny. Implied to have once possessed at least average intelligence; repeated memory wipes by Susan and Mary to cover their bungled attempts to woo him, have left Gil with severe brain damage, to the point he can't even write his own name.
- Laser-Guided Amnesia: A rare naturally occurring case. He pretty much never remembers Susan and Mary's names even though he knows their younger brother. Later, it was explained that the twins always wipe Gil's mind after their botched attempts to woo him.
- Meaningful Name: It's a play on "Girl Next Door", because he is the object of affection for people who live next door to him; and gender-flipped for added up-to-dateness.
- Nice Guy: Stupidity aside, Gil seems like an overall decent guy who likes hanging out with Johnny.
- Oblivious to Love: Like you wouldn't believe...
- Prehensile Hair: As a member of the Johnny Saving Six.
- Pretty Boy: His looks constantly swoon Susan and Mary Test.
- Red Eyes, Take Warning: Upon being released from the metal box after the defeat of the boy robots, his eyes glow red with rage.
- Satellite Love Interest: Most of his role in the show is being the object of Susan and Mary's affections and their trying to woo him. Other times involve hanging out with Johnny.
- Surfer Dude: Blonde, tanned, and frequently spouting surfer lingo like "Cha."
Eugene "Bling-Bling Boy" Hamilton
Eugene "Bling-Bling Boy" Hamilton
Voiced by: Lee Tockar
A rich kid who lives with his mother on a remote island. He is one of the main antagonists of the series yet is sometimes an anti hero. He is very rich and is obsessed with bling and shiny things as his nickname implies. His evil schemes are mostly attempts to flirt with Susan Test, who he has a one sided crush on.- Abhorrent Admirer: He loves Susan Test but she wants nothing to do with him due to his repulsive appearance and overbearing personality. In one episode, Eugene was given a formula that made him stop loving Susan. He started loving Mary instead (it only lasted that one episode).
- Big Bad Wannabe: He is close to being a main villain, but is outclassed by most of the other villains.
- Big Eater: The episode "Lakeside Johnny" is the first time this trope is shown as Bling-Bling Boy effortlessly stuffs his face with bacon.
- Bodyguard Babes: Initially had some red-haired female designed androids that acted as his enforcers and they appeared infrequently through the first two seasons before they were never seen again for the rest of the series.
- Casanova Wannabe: Try as he might, the kid ain't a ladies man.
- Catchphrase: "SUSAN TEST! GO ON A DATE WITH ME!"
- Cut Lex Luthor a Check: Is just as guilty of this as Susan and Mary, with most of the stuff he makes being geared towards futilely trying to get Susan to fall in love with him. His assistants are very understandably frustrated with him about it.
- Disappeared Dad: Never been seen or mentioned once, which suggests that his mother is either divorced or a widow.
- Ditzy Genius: His obsession with Susan and reliance on hired scientists can make you forget he's as much a super-genius as Susan and Mary.
- Friendly Enemy: Even though he and Johnny are enemies, Bling-Bling actually admits that he enjoys their little scuffles. When the super-villains capture Johnny, he admits Johnny is the only one who can stand his temper tantrums and goes to rescue him.
- Insistent Terminology: He hates being called by his real name, Eugene.
- As of now, he doesn't even bother correcting people anymore, suggesting he's accepted that no one will ever call him Bling-Bling Boy.
- Island Base: The aptly named Bling-Bling Island which he operates out of. It's implied it's his mothers though.
- Large Ham: He tends to shout a lot and tries to act grandiose when he can.
- Murder the Hypotenuse: Bling-Bling plotted to get rid of Gil so Susan would focus her attention on Bling-Bling Boy.
- Not-So-Harmless Villain: While his attacks normally revolve around getting Susan to be his girlfriend, when he snaps on occasion, he is extremely dangerous. Never underestimate a genius with infinite funds and a huge army at his disposal.
- Only Friend: Johnny may be his Arch-Enemy, but he also doubles as Eugene's only friend. As it's pointed out above, Johnny is the only person who can stand him.
- Prefers Proper Names: Bling-Bling has a tendency to sometimes call Johnny "Johnathan." A few other characters do it rarely throughout the series, but the former does it the most often.
- Stalker with a Crush: Has a huge crush on Susan.
- Villain Decay: As the seasons went on, Eugene became less and less evil until he became the Token Evil Teammate.
Sissy Blakley
Elisabeth Olivia "Sissy" Blakley
Voiced by: Brittney Wilson (seasons 1 and 5); Ashleigh Ball (seasons 2-4, 6)
The next door neighbor of Johnny Test. She is a stubborn and gruff girl who has a love-hate relationship with Johnny. She owns a dog named Missy (later named Poochy), who Dukey has a crush on.
- Belligerent Sexual Tension: With Johnny. They are often rivals towards each other yet still show that they do admire each other.
- Chuck Cunningham Syndrome: Rarely shows up in later seasons. She's outright missing in the reboot.
- Distaff Counterpart: Her design and attitude is essentially a female Johnny, though she's presented as more mature.
- Expy: Of Susie Derkins.
- Lightning/Fire Juxtaposition: With Johnny, which serves to emphasize Sissy as a Distaff Counterpart to him. Whereas Johnny possesses hair shaped like flames, Sissy's hair features a distinctive zigzag shape resembling a lightning bolt.
- Ship Tease: With Johnny, with it repeatedly made clear the two do have feelings for each other.
- Tsundere: Sissy tends to hide her crush very well through bullying Johnny and asserting superiority over him.
Bumper Randalls
Mitchell "Bumper" Randalls
Voiced by: Scott McNeil
He is Johnny Test's bully from school. He likes bullying Johnny a lot, making Johnny use his sister's experiments to try to stand up to him.- The Bully: He is basically a stereotypical bully.
- Chuck Cunningham Syndrome: He's mostly prominent in the early seasons, and shows up less and less in later ones.
- Hidden Depths: Apparently likes caring for roses.
- Real Men Wear Pink: Despite being a huge bully, he likes to take care of roses.

- Would Hit a Girl: In the episode "Johnny Fu", he hits girls without a second thought.
Janet Nelson Jr.
Janet Nelson Jr.
Voiced by: Kathleen Barr
- Chuck Cunningham Syndrome: She was a prominent character and recurring love interest for Johnny in season 1. She gets reduced to a mere background character season 2 onwards and is never really mentioned again.
- Demoted to Extra: She was only seen for the past few episodes in Season 1 before she was demoted to a background character in later episodes.
- Lovable Alpha Bitch: She's shallow, mean, and stuck up, but still adored by everyone.

Mr. Black and Mr. White
Mr. Black and Mr. White
Voiced by: Bill Mondy (Mr. Black), Scott McNeil (Mr. White, seasons 1-6), Deven Mack (Mr. White, revival series)
They are two bumbling and washed up federal agents who are often seen together. They first appeared as villains in the second episode of the first season but have lost their edge and have become friends with the Test family. They are very incompetent at their job and rely on the Test family to get them out of any messes that they themselves caused. Their ultimate dream is to have a vacation in Fiji together.
- Ambiguously Human: Mr. Black and Mr. White are suggested in their first appearance that they are not humans, despite looking such. This is because they were able to shoot webs out of their wrists in their first appearance, which heavily implies them to be mutants of some sort. They even try to cover up their powers from the public. This is weird because they have never used their web slinging power in all their future appearances after their début.
- Catchphrase: What's their favorite vacation spot? "We are going to Fiji! We are going to Fiji!"
- Cool Shades: They are never seen without their sunglasses on.
- Cross Dresser: Mr. Black and Mr. White once cross dressed as Susan and Mary Test for a Halloween Party but Susan and Mary dressed up as them
- Expy: They are similar to and are parodies of Agent J and Agent K.
- Heterosexual Life-Partners: Although the "Heterosexual" part drops dangerously low at times.
- Ironic Name: Despite their names, Mr. Black is the white agent and Mr. White is the black agent. It should be the other way around.
- Manchild: Both Mr. Black and Mr. White as they are both federal agents who appear to be in their early 30's yet the rely too much on the Test family to help them and are shown to be very irresponsible, Mr. Black in particular cries a lot like a baby in some episodes.
- The Men in Black: Kinda. They don't exactly do much good when they even appear. Usually they end up coming to Johnny, Dukey, Susan, and Mary for help.
- Real Men Wear Pink: They are both federal agents who look intimidating through their agent outfits and shades but they both love cooking and admitted that they once worked as salesmen who sold perfume.
- Shout-Out: You could probably guess this one from two miles away.
- Sweet Tooth: Mr. Black as in one episode, his stomach shown to be digesting a lot of junk food.
- Theme Twin Naming: They are not brothers and they are not twins. Their first names are unknown and their last names don't rhyme but their last names are directly named after the colors of black and white.
- Those Two Guys: They are sometimes seen in episodes that don't involve them doing any missions as they try to protect a hotel under thereat of demolition because they appreciated its architecture and they also showed up at a Halloween party.
The General
The General
Voiced by: Lee Tockar
He is Mr. Black and Mr. White's boss and is the one in charge of maintaining national security in the areas around Porkbelly city. However, he can be sometimes bumbling.
- Cool Shades: He frequently wears sunglasses in his screen time. He is seen taking them off once.
- General Ripper: His obsession for war has earned him this title well enough.
- One example in "Johnny Meets the Pork-Ness Monster", he sunders a whole Platoon of Rocket Artillery Trucks and a couple Squadrons of Attack Helicopters, just for them to pull off a fireworks show over Lake Pork Ness.
Hank Anchorman
Hank Anchorman
Voiced by: James Arnold Taylor
He is Porkbelly's primary anchorman and news reporter. He often reports Johnny's misadventures on television
- Kent Brockman News: Hank Anchorman tends to be somewhat eccentric when delivering news. This trope is mostly how he runs his entire news operation.
Brain Freezer
Brain Freezer
Voiced by: Louis Chirillo (seasons 1-4); Bill Mondy (seasons 5)
- Arm Cannon: Brain Freezer's super cold coffee brewer was remade into an arm cannon once he got a set of Powered Armor.
- Card-Carrying Villain: He is well aware he was evil, though sometimes wishes he wasn't.
- Elemental Hair Composition: Invoked. After turning to villainy, Brain Freezer shoots himself with a blast of his own ice cannon, turning his skin blue and freezing his hair into a mess of icicles.
- Heel–Face Turn: Brain Freezer seems to have dropped his evil ways since taking a level in handsomeness. In his next appearance, though, he was back to being evil in one of the most egregious examples of Status Quo Is God.
- Pungeon Master: Enjoys making bad cold-related puns.
- Shout-Out: An Ice themed Villain who makes the worst kind of ice related puns? Where have we heard that before?
- Trademark Favorite Drink: He loves iced coffee.
- You Need to Get Laid: A recent episode shows that after acquiring good looks and a new coffee shop, he is much less interested in taking over the world and revenge.
Doc Beebles
Doc Beebles/The Beekeeper
Voiced by: James Arnold Taylor
He is one of the villains that Johnny Test has to deal with. He is obsessed with bees and beekeeping and has the tendency to exaggerate words like "be" by putting references to bees in it. Unlike other villains of the show, Doc Beebles did not want to cause harm to the world and its citizens as his only desire was for kids to eat healthier and exercise more, but he often go to highly extreme and unorthodox methods on order to achieve this goal.- Anti-Villain: He does not desire world conquest or total annihilation. He only became a villain with good intentions as he just wanted kids to eat healthy and live long lives.
- Bee-Bee Gun: The Beekeeper has set himself as the artificial queen of his swarms of bees and is able to command them to carry out tasks life theft and attack.
- Evil Sounds Deep: Via his bee suit when he has the helmet on.
- Heel–Face Turn: His only goal was just getting kids to eat healthier via his granola bars which Johnny eventually admitted didn't taste so bad. When Johnny attempt to do a improptu candy-giving holiday during the summer season failed for various reasons ( lack of a good mascot, being sued by the Easter Bunny etc), Beebles had the resources to do the holiday without any of the flaws (has a recognizable name, bees that could help him give away free granola bars and get kids to eat healthier in the bargain). Once he was able to achieve that, he no longer had a grudge against the Test siblings. And as a result, beyond a single mention in the third season finale, he never appeared again.
- Verbal Tic: Puts an emphasis on any instance of "be" that comes up when he talks.
- Well-Intentioned Extremist: In his first appearance, one of his main motives was to get kids to start eating healthier by stealing all of the sweets in town. What he doesn't seem to realize is that not only is he hurting the candy industry, his use of presumably genetically-modified bees makes him an eco-terrorist.
Dark Vegan
Dark Vegan
Voiced by: James Arnold Taylor
An alien from a planet called Vegandon whose species are vegetarians. He was initially the planet's ruler who destroyed other planets to sustain his own until Johnny Test came along and caused him to be marooned on Earth. Since then, he has been obsessed with destroying Johnny but always fails to do so. He also has an unhealthy obsession with eating toast.
- Aliens Love Human Food: After he was stranded on Earth, he developped a love for toast to the point where he chose to stay on the planet since they don't have toast on Vegandon.
- Aliens Speaking English: He and his species speak the same language as Johnny.
- Even Evil Has Loved Ones: His one main redeeming trait is that he does genuinely care about his wife and daughter.
- Human Aliens: He and his species, the Vegans, bear a striking resemblance to the humans on Earth. The only difference is that they are all vegetarians.
- Jedi Mind Trick: Since he’s a parody of Darth Vader, he can use a Vegan Mind Wipe to make someone highly suggestible. The only catch is that it only works on dumb people. Notable victims are Hugh Test and Gil.
- Laser Blade: What do you expect? He's a parody of Darth Vader or maybe Dark Helmet.
- Planet Looters: He kept Vegandon pristine by stealing the natural resources of other planets, leaving them to become lifeless deserts. After meeting Johnny and Dukey, he sets his sights on Earth as his next target.
- Trademark Favorite Food: TOAST! (Note that he only learns about toast later in the series.)
- Villain Decay: Justified as the result of living on Earth, as he can't replace his weapons which are from his own planet.
- Well-Intentioned Extremist: In his original appearance, he only destroys other planets to sustain his own planet (though apparently, this isn't really needed). After that, he's more in it for revenge.
Mr. Whack-O
Mr. Whack-O
Voiced by: Lee Tockar
He is a selfish and greedy executive of a toy company who constantly disregards the happiness and well-being of children.
- Corrupt Corporate Executive: He's the head of a toy company named after him, but devotes all his time to finding ways to get rid of kids.
- Cut Lex Luthor a Check: Averted, sorta. His board of directors asked him if they'd go out of business if his plan succeeded. Turns out he'd already thought of that and programmed his robots to offer to 'babysit' the kids for free to keep their parents happy. Still, he's a brilliant enough man that his smarts could be better spent elsewhere.
- Devil in Plain Sight: His company is still afloat despite him being obviously psychotic and his company producing extremely dangerous toys with the intent to maim or 'get rid of' kids. Handwaved in that his legal team is apparently extremely good.
- Disproportionate Retribution: He built an army of extremely powerful robots to imprison kids in their own houses just for annoying him.
- Legion of Doom: He's the leader and founder of the 'Johnny Stopping Evil Force Five'.
Jillian Vegan
Jillian Vegan
Voiced by: Marÿke Hendrikse
She is the alien daughter of Dark Vegan. She does not approve of her father's evil ways towards humans and her own people. She also has a crush on Johnny Test, who her father is obsessively trying to exterminate.
- Human Aliens: Like her father, Jillian looks like an ordinary human from Earth.
- Precocious Crush: A rare inversion: Jillian, who is five years older than Johnny, has a crush on him.
- Rebellious Princess: Dark Vegan's daughter. Doesn't approve of his destruction of other planets.
Mr. Mittens
Mr. Mittens
Voiced by: James Arnold Taylor
- Cats Are Mean: An evil cat.
- Evil Counterpart: To Dukey in that he was given his intelligence and human-like traits with the exact same method as Dukey did. He's just a lot more motivated.
King Zizrar
Zizrar, The Mole King
He is the ruler of the mole people and lives underneath the Earth's crust. He desires to invade and conquer Earth but is often prevented from doing so because the eyes of his species are very sensitive to sunlight.- Ambiguously Gay: Zizrar and his entire race are all male and most of his minions wear biker leather. Also, Zizrar is flamboyant and is dressed up like a Camp Gay. The only thing putting him in the ambiguous category is that he never flirted with anyone.
- Blinded by the Light: Zizrar's eyes, like those of his entire species, are very sensitive to light as any kind of light temporarily blinds him. Some examples include sunlight and lights from a flashing camera as Johnny used the latter to defeat Zizrar in their first encounter.
- Butt-Monkey: In the snow day episode, Zizrar gets unintentionally beaten up by Johnny an some other people as his eyes got blinded by sunlight and he gets run over by snowboarders.
- Even Evil Has Standards: Depending on the Writer. While some of his ploys would logically cause lots of harm, in at least one instance - where he plans to cave in a library to deprive humans of knowledge and make them stupid & easily beaten - he insists on telling said humans about his plan ahead of time to make sure nobody is inside the building when he destroys it.Zizrar: I want to make the humans stupid, but I don't wanna hurt anybody! We're mole people, not monsters.
- Sissy Villain: He is the first villain of the series but his flamboyance and campy attitude are what make him fit as one.
- Starter Villain: As seen with Sissy Villain above, Zizrar is the show's first villain.
