He's your nontypical cockroach. Representing a city-born snaggle-toothed bum that flirts with drugs and sells out on larvae, he doesn't look all that smart and intellectual. But don't judge a bug by it's bite.. Roach may not be pretty on the outside, but he's a great friend to many and is well-respected in his area. His best friend is his faithful dog named Leech and the two are rarely seen apart from one another.
