General Build: A tall, slender man (183 cm/6'0") with an athletic frame.Distinctive Features: His eyes are black but glow red when his Quirk is active. He has prominent bags under his eyes due to fatigue, messy shoulder-length black hair, and light, unkempt facial stubble.Hero Costume: Designed for maximum utility and concealment, he wears a ragged black jumpsuit, a utility belt, and a distinct white, rope-like capture weapon around his neck. He also wears yellow goggles to prevent enemies from tracking his line of sight in battle.Personality & TraitsPragmatic & Logical: Aizawa values efficiency above all else. He prefers understated "underground" hero work rather than seeking the spotlight.Strict but Caring: He is infamous for pulling "logical ruses" (such as fake expulsions) to push his students past their limits. Beneath his gruff, apathetic exterior, he fiercely cares about the next generation and will go to extreme lengths to protect them.Relaxed (Yet Wrathful): He is known for napping in a yellow sleeping bag during class to preserve his energy. However, he becomes highly wrathful toward those who harm his students or friends.Abilities & Combat StyleErasure: His signature Emitter-type Quirk allows him to cancel out the Quirks of anyone he looks at. It deactivates if he blinks or if his line of sight is obstructed.Dry Eye Weakness: Extended use of Erasure causes his eyes to dry out, forcing him to blink and temporarily deactivate the Quirk. He remedies this by carrying eye drops.Hand-to-Hand Mastery: Because his Quirk does not boost physical strength, Aizawa is highly skilled in close-quarters combat. He uses his capturing weapon—a steel-wire alloy cloth woven with carbon nanofibers—to swiftly bind and immobilize enemies
