Johnny Test - Plot

Plot

Johnny is part of the fledgling Test family, which consists of his 16-year-old genius identical twin sisters, Susan and Mary, and his over-the-top parents, his mother Lila, who is a full-blown workaholic businesswoman who works like the stereotypical father of the family nearly all night and day, and his father Hugh, who is an obsessive-compulsive househusband whose two biggest obsessions are cleaning and cooking meatloaf. The Test Twins frequently use Johnny as a guinea pig for their various experiments and inventions (thus their surname of Test) in their laboratory filled with highly advanced technology built in over the Tests' household attic, with most of which they try to impress their pretty boy next-door neighbor, Gil, with whom both harbor a deep love and obsession, although their attempts to come up with something new and/or another in order to attract his attention always end in failure.

Johnny is the troublesome and widely disrespectful bratty kid who is generally the cause of problems in the city, and he is best friends with his anthropomorphic talking (and talkative) pet dog, Dukey, who is a mutt whom Susan and Mary gave human-level intelligence and the ability to speak in an experiment when he was a puppy. Because Johnny has Susan, Mary, and Dukey by his side, he gets to live any kid's dream, only to find that some dreams are not worth living. 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. Johnny hates school and does not 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 trouble as a result.

As for Susan and Mary, though they generally refuse to help Johnny in his antics, they generally end up doing so anyway due to Johnny blackmailing or manipulating them, or in exchange for Johnny allowing them to use him as their aforementioned lab rat. Their hard-headed demeanor makes them gullible, and they have been tricked by Johnny on various occasions. And Dukey, whom Johnny likes to take places, sometimes dresses as a human being when going out in public, usually in a shirt marked 'NOT A DOG', and he is addressed by others as Johnny's "hairy friend" or "the kid with the rare hair disorder" because the minor characters' lack of intellect causes them to believe that Dukey is a human. In later episodes, when Dukey is not dressed like a human and someone hears Dukey say something to Johnny, they will ask "Did that dog just talk?", to which Johnny quickly replies, "No, you're just hallucinating."

Johnny's main arch-nemesis, however, is Eugene "Bling-Bling Boy" Hamilton, a fellow arch-rival of the Test sisters and friendly pal and enemy of Johnny and Dukey, who acts as one of the recurring evil forces at work. He has a big crush on Susan, who does not reciprocate his feelings and generally shows no interest in him, often leaving him to force her to be his girlfriend. Since Season 3, Johnny has also gained a second major rival, Dark Vegan, a space warlord from the planet Vegandon, of which he is leader. On the other hand, the girl who may have a crush on Johnny, Sissy Blakely (who serves as Johnny's female rival as well, and has a pink laberdoodle named Missy, who is also Dukey's rival and mate), fellow bully Bumper, the General, from the army base Area 51.1, and Mr. Black and Mr. White, two federal agents from the Super Secret Government Agency (SSGA), sometimes help, distract, and/or annoy the Tests on most various occasions.

His catchphrase is "Whoa, didn't see that coming" during an unexpected event. There have been minor alterations to that phrase and in some cases, others have said it, including Dukey; meanwhile, the twins have a habit of speaking in unison, especially when reciting their catchphrase, "We're such geniuses." Other recurring catchphases including "Come on!", "Say wha...?!", "To the lab!" and most recently "That was convenient," when some mistake of Johnny's turns out in his favor.

The backstory given to the Johnny Test character was that it was his 11th birthday, and for the ultimate birthday gift, for a while, Johnny wanted a dog as his present, so he chose a mixed-breed dog, who was once the "smelliest, mangiest and friendliest mutt" that he could find at the dog pound, and named him Dukey. But Susan and Mary, since they hated stupid smelly dogs, decided to genetically alter him so that he will have human-like abilities so that he will stop being and acting like one. Meanwhile, Johnny's enemy, Bling-Bling Boy, had once attended the same exclusive school (The Porkbelly Mega Institute of Technology) that his sisters do, but he got expelled after an "unfortunate incident" that resulted in their teacher, Professor Slopsink, receiving a metal claw for a hand, hence why Bling-Bling Boy currently serves as an evil boy genius who will stop at nothing to get Susan (and win her love), and occasionally, to take over the world.
