Jenny Test

Jenny Test or rather Johnny Test was originally a young boy but his nerdy older twin sisters Susan & Mary had reworked one of their experiments, "The hotty body flakes" and made a MKII of the experimental salt.

Originally was an 11-year-old boy, Johnny is part of the Test family, consisting of his 13-year-old genius twin sisters, Susan and Mary, and his over-the-top parents. His mother, Lila, is a businesswoman, and his father, Hugh, is an obsessive-compulsive househusband. Hugh's two biggest obsessions are cleaning and cooking meatloaf. Susan and Mary frequently use Johnny as a guinea pig for their various experiments and inventions in their laboratory filled with highly advanced technology built over the Tests' household attic. Most of them involve trying to impress their pretty boy-next-door neighbor, Gil, for whom both harbor a deep love and obsession, although their attempts to come up with some way to attract his attention usually fail.

Johnny is now a mischievous and unpredictable young woman of 18 years old who causes many problems (often reaching within the city). Her best friend is his anthropomorphic talking pet dog, Dukey, who Susan and Mary gave human-level intelligence and the ability to speak in an experiment. Because Jenny has Susan, Mary, and Dukey by his side, she can live any kid's dream, only to find that most dreams never turn out as hoped. Johnny is very hyperactive and often messes with his sisters' inventions, causing trouble and mayhem, but just as often proves himself to be clever, such as frequently tricking his sisters or saving the day from whatever danger happens to show up. She is also stubborn, and like many kids, she doesn't like school; if anything, she will often go to great lengths to avoid any work, often using his sisters' inventions to do so, resulting in herself and others in trouble. Despite this, she shows compassion often and always realizes and tries to fix his mistakes.
