8. Bitch-Stewie (Family Guy)
In the episode "Quagmire's Baby", Stewie Griffin genetically engineered himself a mentally-challenged and deformed clone and called it Bitch-Stewie. He was made to serve Stewie, for chores such as washing his back in the bath (in which he would also take the blame for the real Stewie defecating) and going to parties in place of him when Stewie couldn't be bothered. He also lived on a "crude peanut paste". Stewie purposely bred out a lot of Bitch-Stewie's intelligence while creating him, so that Bitch-Stewie's intelligence would not stalemate his own and so he would be more obedient. Due to a genetic defect, he and Bitch-Brian (the Brian Griffin clone that Stewie made Bitch-Stewie create due to his own laziness), dissolve by the end of the episode.
