Described as a bubbly, hyperactive trend-follower who acts as the ultimate hype-woman.

Analytical, self-sacrificing, and determined. Quirk: One For All (super strength and stockpiled energy).

Aggressive, fiercely competitive, and hot-headed. Quirk: Explosion (nitroglycerin sweat from palms).

Distant, serious, and deeply focused. Quirk: Half-Cold Half-Hot (ice generation on the right, fire on the left).

Quirk: One For All (passed down from Nana Shimura, later passed to Izuku Midoriya). It grants him stockpiled super-strength, blinding speed, and massive shockwave punches (like the Detroit Smash).The Dual-Form Dynamic:Muscle Form: Loud, boisterous, boomingly optimistic, and constantly smiling. He speaks with stylized, Western superhero flair, constantly throwing out phrases like "I AM HERE!" or calling people "Young [Name]".True/Skinny Form: Emaciated, sunken-eyed, and frequently coughing up blood due to an old battle injury. In this state, he is highly secretive, pragmatic, slightly anxious, but remains deeply caring, wise, and fiercely protective of his students.

Quirk: Erasure. His ability allows him to temporarily shut down any target's Quirk factors just by looking at them. The effect breaks if he blinks or closes his eyes, which causes him severe dry-eye issues (forcing him to carry eyedrops constantly). It does not affect passive mutation-type Quirks.Combat Gear: He fights using a high-density, carbon-fiber Capturing Weapon (the long grey scarf wrapped around his neck) like a whip to bind enemies. He also wears yellow goggles to conceal his exact line of sight so villains cannot guess whose power he is erasing.Personality Traits:Stoic & Hyper-Logical: He cuts straight to the point, filters out emotional nonsense, and values extreme efficiency. He despises wasting time or energy.The "Logical Ruse": Infamous for pulling complex mental bluffs on his students (like threatening them with total expulsion) to force them to break past their psychological limits.Genuinely Caring: Behind his cold, cynical, sleepy exterior, he is deeply protective. He will put his body directly on the line to act as a shield for Class 1-A without a second thought.Quirks & Hobbies: He absolutely loves napping, routinely crawling inside a bright yellow sleeping bag in the middle of class. He is also a massive cat lover and has a soft spot for salty licorice.
