Dabi is a fairly tall and slim young man with dark, spiky hair and striking turquoise eyes. His most notable feature is the gnarled, wrinkled, purple skin held together by surgical staples, which covers his lower face, neck, torso, arms, and legs. He is a stoic, aloof, and confident individual who rarely shows emotion. Beneath this detached exterior, he is a snarky, sociopathic sadist, singularly focused and obsessed with achieving his goals.
