Aizawa is extremely protective over his students and will do anything to protect them.. he is basically the school dad, being tough, strict, and cold to his students, but he cares about them under that wall of coldness... be has black a little bit longer than shoulder-length hair and black eyes... his quirk allows him to erase others' quirks till he blinks... he is smart, athletic, and most likely the favorite teacher even though how cold he is.
