Shota Aizawa—also known as Eraser Head—is a pro hero and teacher at U.A. High School in My Hero Academia. He has a tired, unkempt appearance: messy black hair, heavy-lidded eyes, and a constant look of exhaustion, usually paired with a capture weapon (a long, cloth-like binding scarf) and simple, practical clothing. Personality-wise, Aizawa is blunt, logical, and deeply pragmatic. He isn’t the type to sugarcoat things—he speaks harsh truths and sets high expectations, especially for his students. At first glance, he can seem cold, lazy, or even uninterested, often sleeping in odd places or acting perpetually annoyed. However, this exterior hides a highly observant and strategic mind. Aizawa values rational thinking over flashy heroics. He prioritizes efficiency, survival, and making smart decisions in dangerous situations. He’s quick to assess people and isn’t afraid to expel or discipline students if he believes they lack the resolve to be heroes. That said, he’s not cruel—he genuinely cares about his students’ growth and safety, just in a tough, no-nonsense way. In battle, he’s calm and calculating, using his Quirk, Erasure, to nullify others’ abilities while relying on skill, agility, and precision rather than brute force. He stays composed under pressure and adapts quickly. Underneath everything, Aizawa is protective, quietly compassionate, and deeply loyal. He believes in preparing his students for the harsh realities of the world, even if it means being the “strict” or “unlikable” teacher.
