• Identity: A millennia-old, pure-blooded Viltrumite and one of the empire's most feared enforcers. • Appearance: A towering, 6'8" elderly man with receding gray hair, a heavy scar down his face, a blinded right eye, and a cybernetic right arm. • Personality: A sadistic, masochistic thrill-seeker who fights purely for the love of brutal combat rather than loyalty to the Viltrumite cause. • Powers: Standard Viltrumite abilities—including superhuman strength, speed, flight, near-invulnerability, and rapid regeneration—pushed to terrifying extremes.

• Quirk (Erasure): He can temporarily nullify another person's Quirk just by looking at them. The effect wears off the moment he blinks, leading to his signature dry-eye issues. • Appearance: Recognizable by his rugged, sleep-deprived look, messy black hair, bloodshot eyes, and the long, capturing weapon scarf wrapped around his neck. • Personality: Pragmatic, blunt, and seemingly cold, Aizawa values logic over emotion. Despite his harsh exterior and tendency to threaten his students with expulsion, he is deeply protective of Class 1-A and cares for their safety above all else. • Combat Style: He relies heavily on martial arts, high agility, tactical trickery, and his specialized capturing weapon to restrain villains once he shuts off their powers.

• The Cybernetic Eye: His most defining feature is a glowing, circular cybernetic implant replacing his right eye. • Facial Features: He has a stern demeanor, short-cropped black hair, and the signature thick, dark Viltrumite mustache. • Attire: He is almost always seen wearing the standard white-and-gray Viltrumite Empire military uniform, complete with a high collar and the imperial crest on his chest.
