Characters: Johnny Test
This is a character sheet for Johnny Test.


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.


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.
  • Adorkable
  • Ambiguously Gay: He has some effeminate mannerisms...
  • Bacon Addiction: Dukey loves him some bacon.
  • Badass Bookworm
  • Balloon Belly
  • Berserk Button: Harming, trying to kill and/or being responsible for Johnny's mortality in front of Dukey.
  • Beware the Nice Ones
  • Big Friendly Dog
  • 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
  • Camp Straight
  • Catch Phrase: "I'm a kid with a rare hair disorder".
  • 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 Johnny, it comes naturally.
  • The Drag-Along: Most of the time unless the situation calls for it.
  • Funny Animal
  • 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
  • Large Ham
  • 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 Paper-Thin 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.
  • 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 most anyone looks sane next to Johnny.
  • The Other Darrin: In Season Five, Louis Chirillo has been replaced with Trevor Devall. And it is EXTREMELY noticeable, with the entire voice pitch changed and Trevor struggling to keep the same inflections with obvious throat pain (going by the rough, scratchy noises). And for all his effort he just ends up sounding like Hugh Test.
  • Screams Like a Little Girl
  • Sensitive Guy and Manly Man: Sensitive Guy to Johnny's Manly Man.
  • Trademark Favorite Food: Dukey would do anything for a steak. Or Bacon
    • Also enjoys coffee.

Susan and Mary Test

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).


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.
  • Brainless Beauty: The boys head is hollow as a coconut.
  • Captain Ersatz: Though both shows came out around the same time, Gil is a local, well meaning blonde kid who is the object of the protagonist's older sister(s) affection, drawing many easy parallels to Jeremy on Phineas and Ferb. The two started to deviate later when they both started being less Flat Character sorts.
  • Catch Phrase: "Hey, Johnny!", or "Tell Johnny I said hi!" whenever Johnny's not around.
  • The Ditz
  • Dumb Blonde: Even more than Johnny.
  • Boy Next Door
  • 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.
  • Oblivious to Love: Like you wouldn't believe...
  • Prehensile Hair: As a member of the Johnny Saving Six.
  • Pretty Boy
  • Surfer Dude: Blonde, tanned, and frequently spouting surfer lingo like "Cha."

  • Child Hater: See below.
  • 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.
  • Genre Blind
  • Legion of Doom: He's the leader and founder of the 'Johnny Stopping Evil Force Five'.
  • Would Hurt a Child: His entire character is this.
