Ralphie Zinobop is an "evil" clone of Ralph Zinobop. Since Ralph was already evil, Ralphie popped out warm, caring and generally the nicest guy you’ll ever meet — essentially, he’s everything that the original Ralph is not. In addition to his personality, Ralphie is left-handed (Ralph is a “righty”), his DNA winds the opposite direction and his fingerprints are reversed.
Roberta Smeffinfeffer is level-headed, if not a little bit insecure. She has the tendency to follow her heart a little too much. Case in point: she's also Ralph (and Ralphie's) ex-wife. She has a background in space biology and studies medicine for awhile. She currently serves as doctor aboard the "Steel Duck."
Well, that’s auspicious.
