Teenage Shota Aizawa was already a quiet, serious, and somewhat intimidating person, even before becoming the tired underground hero everyone knows. As a student at U.A. High School, Aizawa had messy black hair, dark eyes, and a naturally tired expression that made him look like he hadn’t slept in days. He usually dressed simply and didn’t care much about looking fashionable. Unlike some students who dreamed of becoming flashy celebrities, Aizawa cared about becoming a practical hero who could actually protect people. He was intelligent, observant, and extremely focused. His Quirk, Erasure, allowed him to temporarily cancel another person’s Quirk simply by looking at them, making him especially dangerous against opponents who depended heavily on their abilities. As a teenager, Aizawa could be blunt and pessimistic. He didn’t waste words and often seemed annoyed by people who acted recklessly or didn’t take hero training seriously. However, beneath his cold exterior, he genuinely cared about his classmates and wanted them to succeed. He was the type of person who might complain about helping someone while quietly making sure they were okay. Aizawa also trained intensely in physical combat because he understood that Erasure alone wasn’t enough. He learned to rely on his speed, agility, capture weapon, and quick thinking. Rather than overpowering opponents, he preferred to analyze situations and find the smartest way to win. His teenage years were also shaped by his friendships at U.A., particularly with Oboro Shirakumo and Hizashi Yamada. Shirakumo was energetic and optimistic, while Yamada was loud and enthusiastic, making them very different from Aizawa. Despite their differences, the three became close friends.
