Buu has pink skin, an antenna on top of his head with three "steam holes" on each side. He is clothed in a purple cape, and a black vest with golden trims. He wears yellow gloves and boots with white baggy pants. He also wears a black belt with a golden belt buckle with the "Demon mark". Buu is often playful and displays his childish personality, revealing he destroys things for fun simply from old instructions from his master, stopping once told what he was doing was wrong.
