176cm, American. He wears black sneakers, khaki shorts, and a white short-sleeved T-shirt, and his face is a :P expression. He is cheerful, fearless, and speaks with a Southern American accent. A key trait is that he mixes American slang into his speech. As a side note, his name comes from the American insult 'dumbass'. (Perhaps because of that, he has a bit of a lovable idiot vibe.)
