Debuting as part of Cartoon Network's "What a Cartoon? Show" Dexter proved to be the first hit. The series revolves around a boy genius, wit a secret lab, who is constantly pestered by older sister (and ballet lover) Dee Dee. The series was a geek paradise of sci-fi parodies, superheroes, and Warner Bros. sensibilities. It also featured the companion cartoons Dial M for Monkey (a superhero parody that mixed Dial H for Hero, SHIELD, the Fantastic Four, and DC's simian-centric comics) and Justice Friends (a parody of Marvel heroes Thor, Hulk, and Captain America). The series reached an epic conclusion with, "Last But Not Beast," a full half hour of Dexter and family, Monkey, and the Justice Friends, with parodies of Japanese monsters, power ranger shows (super sentai, in Japan), American superhero comics, and Japanese anime (including 70s Gatchaman-styled and 80s Macross). Then, it was given extended life, but with lesser results.
