Devo is a tall Native American of muscular build with long dark hair. His face and body are covered by countless scars: the results of Devo letting his opponents attack him. At first, Polnareff believes Devo to be a complete idiot, since he was hiding in the fridge of Polnareff's room and left all the drinks outside above said fridge, making himself easily detectable. But Devo pretended to be sloppy to be detected by Polnareff and get hit by his Stand. He is also extremely sadomasochistic.
