Dabi is a rude and argumentative person who has no sense of respect. He introduced himself to Tomura informally, and refused to give out his real name. After renaming himself Dabi, he became a stoic, aloof, confident, and focused individual who rarely shows emotion. As one might expect from someone who named their Quirk, and whose villain name translates to "Cremation," Dabi is a pretty dark and sadistic individual.
