Shota Aizawa

Shouta Aizawa (相澤消太, Aizawa Shōta) is a Hero and the homeroom teacher of Class 1-A

Appearance
Shouta has shoulder length black hair with some hanging down, a half-shaved beard, mustache, and has a very tired look. He wears a black clothes, with an iron scarf wrapped around his neck along with goggles. In his classroom he is often seen snuggled in a sleeping bag.

His hero outfit consists of black clothes, a utility belt, black shoes, a scarf wrapped around his neck, and goggles over his eyes. In addition to the change in attire, he brushes his hair backwards.

Personality
Shouta appears to be a man of high expectations, as he is known to expel students whose chances are below the "zero" mark (once expelling an entire class of first graders) as noted by All Might, showing that he has a cold-hearted emotionless nature. Despite this dark personality, he does care for his students, as when the villains showed up at the rescue trial training area, he told No. 13 to protect his students while he fights the villains.

Quirk Apprehension Test Arc
Shouta introduces himself to his students, telling them that he is their homeroom teacher of Class 1-A. He then instructs them to change into their P.E uniforms as they will be having a Quirk Apprehension Test. Shouta then has Katsuki show his students a preview of what the Quirk Apprehension Test will be like. After the students think that the test is going to be fun, Shouta then makes a new rule: the student who ranks the lowest wil be expelled.

Shouta then records his students' performance in each of the trials. When Izuku throws the ball during the pitch trial, Shouta nullifies his Quirk, causing Izuku to have a low score. Shouta then explains that from his observation, Izuku is unable to efficiently use his Quirk and rhetorically asks Izuku if someone would save him. Izuku tries to explain, but Shouta wraps Izuku with his cloth, proving his point of no one rescuing him. Shouta tells Izuku that he may have courage but he will simply be a burden that needs saving all the time and then concludes to him that his "power" won't help him become a hero if he needs to be saved. Shouta decides to let Izuku have a second chance. He then predicts that Izuku has zero probability, but after Izuku threw the ball a great distance without greatly injuring himself, Shouta is surprised yet happy at the same time.

After an enraged Katsuki tries to strike Izuku, Shouta uses his cloth to restrain him from doing so. At the end of the test, Shouta shows everyone's rankings in the test and then reveals that he lied about the expulsion rule, saying that it was a logical ruse that would get the best out of everyone, much to the students' shock. He tells his students that their curriculum sheets are in their classroom and tells Izuku to see Kango Kyouyu to have himself healed. As he walks away, All Might approaches him, calling him a liar and says that he once expelled an entire new class of first-graders last year. All Might knows that he kicks students out with zero chances, finding it weird that he didn't expel Izuku on the spot and concludes to him that even he felt Izuku's raw potential. However, Shouta replies that Izuku's are above the "zero" mark and that it all. He continues to say that he can kick anyone out whose chances drop below that mark at any time, then leaves.

Rescue Trial Arc
Shouta reviews the results of the battle trial, telling Katsuki to stop being childish as it is wasting his own talent, then encourages Izuku to not hesitate in using his Quirk, asking him to work harder. He then tells the class that they need to pick a Class President and can do anything to elect one as long as they meet the deadline.

Shouta then tells his students that they will be having a rescue trial training exercise, supervised by him, All Might and another hero. He then instructs his students to get prepared. At the rescue trial training area, Shouta asks No. 13 where All Might is, to which he is then told that he is taking a nap after doing his job as a hero. Shouta decides to begin the rescue trial exercise without him. After No. 13's speech, Shouta feels an ominous presence, looks behind him and sees villains appearing out of nowhere. He tells his students to huddle together and orders No. 13 to protect the students while he prepares for battle. He then realises that it was them who broke into Yuuei the previous day.

Shouta orders No. 13 to evacuate the students and tells Kaminari to try contacting Yuuei with his Quirk. Although Izuku expresses his doubt in his teacher's ability to fight all the villains alone, Shouta says that a hero has more than one trick up his sleeve and tells No. 13 that he is counting on him. Shouta begins his battle, using his cloth to wrap three villains and then uses it to smash the villains into each other. He is approached by a mutant shape type Quirk user who says that he cannot erase their types of Quirks. Shouta calmly says he is unable to do so and proceeds to deliver a powerful punch in the face to the mutant Quirk user, sending the mutant flying back. Another villain tries to attack, but Shouta uses his cloth to grab the mutant's leg, reels the mutant in and smashes him into the other villain. Unfortunately, Shouta is unable to stop on of the villains from getting to his students. Shouta then proceeds to continue his battle against the villians.

Shouta then confronts Shigaraki Tomura, wondering if he is the leader. Shouta tries to land an elbow strike against Shigaraki, but Shigaraki manages to grab Shouta's elbow and begins disintegrating it, but Shouta counters and punches him with his other arm. Shouta is then approached by a monstrous villain. Although he put up a valiant effort, Shouta is defeated by the monstrous villain.

Quirk
"Eraserhead" - Shouta's Quirk allows him to cancel the power of any Quirk by looking at someone.

A drawback to this Quirk is that if he uses his ability for a long period of time, his eyes start to dry, and if they close, the Quirk stops working. Another drawback is that Shouta's Quirk can only work on emitter and transformation class Quirks.

Equipment

 * Capturing Weapon: A cloth that is made for a steel wire alloy woven with carbon nanofibers. Shouta uses his cloth in order to capture targets so that he doesn't have to use his Quirk.


 * Goggles: Shouta wears a pair of goggles around his neck when not in combat and puts them on when he is in combat. These goggles compliment and work effectively with Shouta's Quirk against large numbers of enemies, as the goggles hide his line of sight, preventing enemies from trying to determine whose Quirk he is erasing, effectively creating confusion even amongst a large group of enemies.
