Mayberry Melonpool is the television-addicted, somewhat clumsy, not-all-that-intelligent Captain of the "Steel Duck." Oh yeah, and he's obsessed with getting a date. In short, he doesn't have a lot going for him.
Ralph Zinobop is the inventor of the "Steel Duck." He is eager to enter the next phase of his plan: to make money off his inventions to regain his rightful place as ruler of the Planet Zinobop — a planet that he was exiled from by his paranoid father several years ago. His other hobbies include wild get-get-rich schemes and drinking copious amounts of coffee. He also has a terrible temper.
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.
Sam T. Dogg is completely out of his element. He’s super intelligent, a highly-skilled pilot and has the most common sense of anyone aboard the "Steel Duck." Also, no one takes him seriously because he’s a dog.
Sammy the Hammy is a genetic experiment gone horribly awry. Sammy is part of the ship’s equipment (he’s the engine) as well as a member of the crew. For this reason, Ralph never bothered giving him a name and he remained known as “Hamster 42” for much of his life.
He really knows how to put the “Ralph” in “Ralphie” sometimes, doesn’t he?
Maybe Ralphie is getting desperate…
