Shota Aizawa, also known as the Erasure Hero: Eraserhead is a character from My Hero Academia.
He is a Pro Hero and the homeroom teacher of U.A.'s Class 1A.
He is voiced by Junichi Suwabe in the Japanese version, who also voiced Leone Abbacchio in Jojo's Bizarre Adventure: Golden Wind . In English version, he was formerly voiced by Alex Organ in the first season and now currently voiced Christopher Wehkamp for the rest of the series in the English version of the anime.
Aizawa is Class 1-A's homeroom teacher. He seems apathetic at first glance, but looks out for his students and pushes them to improve. He is also the pro hero Eraser Head. His Quirk, "Erasure", allows him to nullify others' control over their Quirks just by looking at them. Blinking dispels the effect of his Quirk and using it gives him very dry eyes.
Aizawa is a very strict and reserved person, with high expectations of his students. He acts mainly by logic and does not believe in the need to always appear clean on oneself, or to filter his words and ideas. He often looks cold, listless and impatient, putting very little energy into what he does, preferring to take naps in his sleeping bag.
A strict teacher, Aizawa is known to fire students he thinks don't fit in U.A. It is however revealed that his high dismissal rate is only on paper, he has a habit of bringing back fired students. Shoto only does this to push them up. He can also be rigid and has little tolerance for disobedient behavior. He's not afraid to push his high school students through rigorous training and make them overcome their limits.
Shoto has proven that he can be very talkative and is not shy about expressing his ideas. He is known to lie to his students, manipulating them into giving their best, a technique he describes as "a logical ruse" "a rational deception".
Despite his apathetic features, Aizawa cares about his students and doesn't hesitate to give anything to protect them, such as when he saved Tsuyu Asui when he was already badly injured. He also showed that he believed in his high school students, and was even confident that Katsuki Bakugo would not go over to the Villains. Recovery Girl also insinuated that during a test, he let himself be captured by Momo Yaoyorozu in order to boost his self-confidence.
