Dabi is a reasonably tall, pale young man of slim shape but somewhat muscular build, described as in his early twenties. He has white hair with a few red flecks at its crown that spikes upward around his head, hanging low over his eyes, which are thin, turquoise, and heavily lidded. Dabi's hair was dyed black before revealing his true identity. His most striking features are the purple burn scars from his fire quirk that covers below his eyes, ears, neck, jaw, collarbone, arms, legs, and torso.
