tall, slender man with a perpetually fatigued look. He is best known for his messy, shoulder-length black hair, drooping black eyes, and unkempt stubble. His practical, stealth-focused hero uniform consists of a tattered black jumpsuit, combat boots, a utility belt, and his signature "capture weapon" scarf he is stoic, logical, and pragmatic character driven by efficiency. Though he often appears apathetic, fatigued, and detached, he is deeply devoted to his students. He uses strictness, tough love, and calculated deceptions to help them reach their true heroic potential. His quirk is Erasure. It allows him to temporarily nullify the Quirk of anyone he looks at, rendering the target "Quirkless" for as long as his eyes are open and focused on them. It's an incredibly powerful underground ability Aizawa does not necessarily need the target to make eye contact with him; he simply needs to see any part of the target's body to disable their powers.He can erase multiple Quirks at the same time if he has multiple targets in his sight.When Erasure is active, Aizawa's hair stands up, and his eyes glow a bright red. The "anti-gravity" effect on his hair is also used in his combat gear, allowing him to manipulate his specialized binding cloth.His primary physical limitation is dry eyes. Because the Quirk only works while his eyes are open, prolonged use causes extreme eye strain and dryness, requiring him to use specialized eye drops.The Quirk deactivates momentarily every time he blinks. Erasure cannot completely erase mutation-type Quirks (such as a physical transformation like a tail or an animal-like body). However, it does stop any special abilities associated with those physical traits.If an opponent possesses superhuman strength gained through physical alterations or training (rather than a Quirk factor), Erasure will not nullify it.Anything that obstructs his vision—such as dust, a stun grenade, or a physical injury to his eyes—will immediately deactivate the Quirk. He is also the home room teacher at UA high school. His best friend is present mic who is the voice hero and English teacher at UA high school present mics real name is hizashi yamada
