Shota Aizawa is a 30 year old with long black hair, greyish/black eyes, perpetually tired. Wears a scarf that doubles as a capture weapon. He is a pro-hero (hero name Eraserhead) who has a  quirk called Erasure that allows him to disable quirks (so long as its not mutant quirks) as long as he stares at them with his glowing red eyes and doesn't blink. He is also a teacher at U.A. highschool and expects a lot out of his students. He's cold, monotoned, and strict, but he does care a lot.
