Johnny Test

Johnathan Test (voiced by James Arnold Taylor) is the main protagonist of the animated series Johnny Test. He is a heroic, albeit troublesome, narcissistic and widely disrespectful 11-year-old boy who was the brother of Susan and Mary and the son and Hugh and Lila. His best friend is a talking dog, Dukey.

He is voiced by James Arnold Taylor who also voices Crash Nebula from The Fairly OddParents, Ratchet from the Ratchet and Clank franchise, and Willy Wonka in the 2005 video game version of Charlie and the Chocolate Factory.

Personality
He is very hyperactive, and often messes with his sisters' inventions, causing trouble and mayhem, but just as often proves himself to be extremely clever such as by frequently tricking his genius sisters or saving the day from whatever danger happens to show up. Johnny can be considered very spoiled and stubborn, as he gets what he wants through deceit, blackmail, or manipulation, though he does love his sisters in a way only a brother can.

Despite his flaws, Johnny is a very caring person, even if the situation he's in allows him to be selfish. A running gag for him is that he often feels bad about and hates seeing people cry, and tries to help them, knowing that will lead to pain and embarrassment. He has felt bad for the numerous occasions he's come out on top, such as when he defeated a desperate penguin army or the time he helped his arch nemesis return to his home planet, despite the threat of being double-crossed and the Earth's destruction. Even when a problem is solved, Johnny doesn't like bittersweet endings and will usually sacrifice as much as he needs to in order to end an adventure happily, or at least in a way that benefits others more than himself.

Physical appearance
He is frequently called the "kid with the flaming hair" due to having scarlet red highlights in his blond hair, which sticks up like Calvin's (of Calvin and Hobbes). As well as this, he is most often seen wearing green cargo pants and a black shirt with a trefoil symbol on it, which he wears under a navy blue dress shirt, and a watch that he rarely uses. He sometimes wears orange, yellow, and dark pink swimming trunks and his disco outfit was a black shirt, dark gray pants, a black cap, blake glasses, a yellow collar, and black shoes.

Powers & Skills
Johnny has an alter ego that he calls "Johnny X", who is a superhero that has various superpowers. A running gag for this form is that his hurricane hands never work, due to either the target being immune to it or to other unforeseen factors.

His most recurring superpowers include his ability to shapeshift, hurricane hands, and his most famous power: "lower posterior energy bursts" or "power poots," which are farts that turn into powerful flames. These powers have no status quo on usage. In one instance he managed to keep his "power poots" for a couple of weeks, while his other powers were neutralized, and in another, his mutant powers ran out due to exhaustion, despite this not happening previously or thereafter.

Though not a superpower, Johnny has been hardened by so many of his sisters' experiments gone-wrong that he has a high threshold for pain. He considers himself to be a master of "Say Uncle," not relenting despite being punched in the face and having his arm twisted behind his back. Whenever his group suffers heinous injuries, he is usually the one with the least amount of bandaging. He is also able to fall off his own roof or from similar altitudes without suffering a serious injury.

Though he doesn't consider any of his family a challenge, Johnny is a cunning manipulator, especially towards them. He is adept at reverse psychology, guilt-tripping and ego-mongering. He frequently cons his sisters into leaving their lab by feigning the attention of their crush who lives next door to them. He is also not above manipulating his best friend into helping him or sharing his embarrassment or pain, if not taking all of it. He also tends to use the same excuse of adopting his best friend as a means of coaxing, even though said excuse has more than run its course.

Due to his gaming habits, Johnny is also a master strategist, often being the one who nails down the final solution to a problem. His experiences in solving problems also tend to come from living the problem within the same episode, except on a smaller scale. An example of this is when he stopped an animated monster truck by introducing it to a girl, after teaching the same lesson to his sisters with their hamsters.

Guitar
He even owns what appears to be a red and black B.C. Rich Warlock guitar that is rarely ever used or seen, Although it can be seen in the intro played and smashed by Dukey and played by Johnny, Dukey, and Bling-Bling Boy in very few episodes. Because he has Susan and Mary by his side, he can live any kid's dream, only to find that some dreams aren't worth living.

Feats
One obvious aspect of Johnny's life is that the experiments he's the test subject for often lead him into trouble. Some of the outcomes have proved to have the most astounding circumstances and be the defining moments of his character.
 * He is the first person to discover real mole people, underwater civilizations, subatomic worlds and aliens, one of which he kept as a pet.
 * He has fought two wars: one with penguins, the other with alien vegans, both of which he won.
 * A switcheroo he employed involving a hand-me-down backpack won his sisters a scholarship and popularity in a sorority (on accident).
 * He is the creator of the "Super Champion of the World Kart Race" and boat version, the former of which he won and got recognized for on TV.
 * He is an official secret agent and has stopped several world domination conspiracies.
 * Two of his best friends are spies, and another is his town's military General.
 * He has made enemies with several supervillains, all of which he's defeated.
 * Saved the world dozens of times, most of which were incidents of his own fault.
 * Defeated a few of his favorite video game protagonists and gained their glory.
 * His sisters are the ultimate in genius prodigies of the time, and he has survived at least 100 experiments they've subjected him to, some of which were lethal and/or physically scarring.
 * He has created two holidays: one was shut down for territorial infringement by The Easter Bunny while the other has succeeded and is carried out by one of his former arch-enemies.
 * His numerous outings of saving his hometown has inspired the townsfolk to make him the resident defender, along with his sisters and dog. However, the townsfolk only seem to remember Johnny's name.

Relationships
Johnny hates school and doesn't work hard at all; if anything, he goes to great lengths to avoid doing work, often using his sisters' inventions to do so and often putting himself and/or others in danger as a result. He is addicted to video games, and will do anything to get them. His catchphrases are "We did not see that coming" and "Hokey smokes." which are usually used during an unexpected event. There have been minor alterations to that phrase and in some cases, others have said it, including Dukey. Johnny is of English, Spanish, Austrian, Canadian, Scottish, French, Swedish and Japanese heritage as seen in "Who's Johnny?" Johnny has a crush on his neighbor Sissy Blankley and Dark Vegan's daughter Jillian.
