Mayberry Melonpool

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.

Sam T. Dogg

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.

Ralph Zinobop

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.

Sammy the Hammy

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.

Ralphie Zinobop

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.

Flatworm Jim

Flatworm Jim was the original pilot of the "Steel Duck." A six-foot-tall intelligent flatworm, Jim’s usefulness was cut short when he was injured, resulting in three versions -- good, bad and a two-headed neutral version. All three (or four) now live on Ralph’s asteroid tending to over 6 million hamsters.

Roberta Smeffinfeffer

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."

Vic was Mayberry‘s former boss and the owner of P.J. O’Earthy’s — an Earth-themed restaurant on a space station in the outskirts of the known universe. Like any T.G.I. Friday’s wannabe, it’s tacky and overpriced and known more for the kitsch than the food.

Eileen is not a very nice person. Some might say that she knows what she wants — or rather — what she doesn’t want. And what she doesn’t want is Mayberry. There aren’t a lot of GRAISE women roaming around the galaxy — leading to persistent rumors that Eileen may or may not be a human-GRAISE hybrid.
