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. Dabi's hair was dyed black before revealing his true identity. Despite his usual expressionless behavior, Dabi finds joy in establishing himself as a villain fighting what he believes to be false heroes.
