Shota Aizawa (Eraser Head)

Shota Aizawa also known as the Eraser Head, is a Pro Hero and the homeroom teacher of U.A. High School's Class 1-A.

Shota is a slender and tall, pale-skinned man with messy, shoulder-length black hair that partially hangs in front of his face and half-opened black eyes. He is usually recognized for his worn-out appearance, often looking fatigued. His facial hair is almost always in a stubbly, unkempt state (unless he needs to look good for the press), and his eyes tired and flat unless he's in combat. He sports a baggy black outfit that consists of a long-sleeved shirt and matching pants that tuck into his boots. He also wears a utility belt and his signature wrap scarf at all times. He hides a pair of bright yellow goggles underneath his scarf for when he needs to use them in battle. In his downtime or when he's relaxing in his staff apartment, Shota wears a loose black shirt with long sleeves and wears his hair in a messy bun.

Shota is a very stern and reserved man who has lofty expectations of his students. He is primarily motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations, preferring to take naps in his sleeping bag instead.

As a teacher with notoriously high expectations, Shota is known to expel students who he feels are not suited for U.A. High. However, it's revealed that this high expulsion rate is only on paper and that he actually re-enrolls the students he expels: Shota does this so they can experience "death" once, giving them an experience that drives them to push even higher. Although it is noteworthy that he has not expelled any students from Class 1-A yet, despite being well-known for doing so. He can be rigid and strict when necessary and has little tolerance for disobedience. Shota is not afraid of putting his students through rigorous training and often pushes the more unpleasant parts of Heroism, so that his students can overcome their limits.

Shota has proven to be very vocal and unafraid when expressing his ideas. He has mentioned on several occasions that some of U.A.'s choices when it comes to examinations are not practical or challenging enough for real Hero hopefuls and is adamant about having certain systems used by the institution changed.[15] He also blatantly stated that he did not believe Izuku Midoriya could become a hero when they first met.[7] He is also known for lying to his students in order to manipulate them into giving their best, a technique he describes as a 'logical ruse'/'rational deception'.

Despite his apathetic traits, Shota genuinely cares about his students and will go to great lengths to protect them. He has also expressed belief in his students on multiple occasions and is confident that even the likes of Katsuki Bakugo would not be swayed by villains. Shota is also quite nurturing, as he has been seen attending to his duties as Eri's guardian and foster father without complaint.

He is shown to be extremely disturbed upon discovering the ultimate fate of his friend Oboro Shirakumo. He displayed intense grief upon confronting Kurogiri after discovering that he is Oboro, showing that Shota has not yet come to terms with his friend's fate. Furthered by this tragedy, Shota is shown to be particularly wrathful towards individuals who are unfortunate enough to provoke him, especially by harming those he cares about. This was seen when Shota strangled Kyudai Garaki after learning of the desecration of Oboro's corpse, blocking Kyudai's longevity Quirk, tormenting and humiliating the aged scientist in a show of sheer rage.

Despite his personality, Shota has shown on several occasions that he is not completely devoid of joy or humor: he often grins whenever he is impressed by one of his students or after he tricks them with one of his 'rational deceptions'.

Overall Abilities: Shota has demonstrated incredible combat prowess and ingenuity that makes him one of the most formidable teachers and Pro Heroes at U.A. High. Shota's usual battle tactic consists of canceling an opponent's Quirk and then using his Capturing Weapon in conjunction with his high agility to easily defeat or restrain his adversaries. Even without the aid of his Quirk, Shota relies on his proficiency in hand-to-hand combat, excelling in close quarters combat. His overall abilities make him a pivotal combatant in situations that involve his opponents being solely Quirk-reliant, and with the Erasure Hero creating openings by negating their powers in the midst of battle, him and his comrades are put into advantageous positions.

Binding Cloth: Shota fights by ensnaring and/or immobilizing his opponents with his capturing weapon, and can also use it for mobility by swinging on walls and surfaces. Immense Stamina: On multiple occasions, Shota was able to keep fighting on even after suffering significant and painful injuries. Keen Intellect: Eraser Head had been seen to have keen observation and evaluation skills. He can easily evaluate his student's personalities and their mental state. He is an expert on collaborating his equipment and Quirk with one another. In battle, Eraser Head uses goggles in conjunction with his Quirk to prevent enemies from figuring out who he's looking at, and keep them guessing.

Erasure: Shota's Quirk gives him the ability to nullify another person's Quirk by looking at the user. The effects of this Quirk can still last even if Shota's line of vision is out of range. While powerful, this ability has many drawbacks: Erasure deactivates if Shota blinks. His Quirk gives Shota a bad dry eye, forcing him to blink more often when he uses the power continuously. Most Mutant-type Quirks are immune to Erasure, given that these Quirks are often passively active in a way that can't be negated. Erasure has zero effect on any strength or abilities that don't originate from Quirks. Erasure makes Shota's hair stand on end while it is active, allowing his enemies to see when his Quirk is active or not. This Quirk has no offensive potential. The Quirk Factor lies within Shota's eyes, so if one or both are damaged or destroyed, he cannot effectively use Erasure.
