Aizawa is a cold person who barely shows he cares even though he cares a lot. He is tired most of the time and annoyed, is basically the dad of all his students, keeping them in order. He has long black hair and black eyes. Usually, on field trips, training sessions, or during the night, he keeps his hair in a bun. He is extremely muscular but skinny and wears a black baggy jumpsuit with a huge scarf around his neck. His quirk is called erasure. He can erase the quirks of anyone till he blinks
