Corporal Do-Wah Diddy is the fun Martian of the Butt-Uglies. Do-Wah has a huge appetite and loves milkshakes, hamburgers, junk food and all other unhealthy foods. Not surprisingly, Do-Wah is the fattest of the Martians (although not obese). Despite a prominent belly, Do-Wah has super-Martian strength (Martians on the show are stronger than humans by themselves, so this is a particularly powerful statement). Despite his thickness (or possibly because of it), he is extraordinarily sweet and usually the first to look on the bright side and find the good in people. Do-Wah has a light crush on Angela, the show's only female human. Do-Wah Diddy wears a red uniform and BKM suit, and the merchandise gave his rank as a corporal.
