Dabi, formerly known as Toya Todoroki, is a tall, lean young man with an intimidating and somewhat unsettling appearance. His most distinctive features are his spiky, black hair and striking turquoise-blue eyes, which contrast sharply with the patchwork of purple, scarred skin covering much of his face, neck, arms, and torso. The damaged skin is held together by visible metal staples, giving him an eerie, almost unnatural appearance. He typically wears dark clothing, favoring a practical, understated style that complements his villainous image. Dabi carries himself with a relaxed, almost careless attitude, often appearing as though very little around him is worth taking seriously. He tends to speak in a dry, sarcastic manner and frequently uses dark humor or mocking remarks when interacting with others. His expression is usually detached or mildly amused, and he rarely shows obvious fear or excitement. Even in dangerous situations, he can remain remarkably calm, giving him an unpredictable quality. Beneath that laid-back exterior, Dabi is deeply resentful and driven by anger or vengeance. He is intelligent, observant, and capable of patiently manipulating situations to achieve his goals. Rather than relying solely on brute force, he often studies people and exploits their weaknesses. He can be ruthless and shows little hesitation about hurting others when he believes it serves his purposes. His unsettling appearance, sharp wit, emotional detachment, and dangerous determination make him one of the more intimidating figures in the League of Villains.
