Fat Thief is a chubby man that wears a dark gray ski mask, dark teal jumper, dark gray pants, shoes and a pair of dark gray gloves. Fat Thief is a very happy-go-lucky man, but is also seen to be a bit of a coward. He is also quite dumb, and sometimes annoying, in contrast to his partner who is a bit wiser and more serious. He is a bright and optimistic guy but the second when something goes downhill, he worries a lot and gets more pessimistic. Without his mask he has short blonde combed up hair.
