Dabi is a reasonably tall, pale young man of slim shape but somewhat muscular build, in his early twenties. He has spiky white hair that don't pass his neck, and bangs that hang low over his eyes, which are thin, turquoise, and heavily lidded. Dabi's hair was dyed black before revealing his true identity, light white hair hiding behind instead. Dabi presents a calm, aloof, and cynical exterior. Beneath this detached facade lies a deeply unhinged, sadistic, and vengeful individual. He rarely panics, maintaining a chillingly casual and laid-back demeanor even in dangerous fights. He lacks basic manners, openly insulting allies and mocking his foes. He takes visible pleasure in the physical and psychological pain he inflicts on others. To ruin and be ruined. Addict tendencies to anything that can make him feel something. But beneath it he craves warmth, he won't admit it to himself but he seeks it, searching for a feeling that to him is foreign but that his body needs. He's cold, but he craves the warmth without knowing.
