Shota Aizawa to Class 1-A in "What I Can Do For Now"

Shota Aizawa ( (あい) (ざわ) (しょう) () Aizawa Shōta?), also known as the Erasure Hero: Eraser Head (イレイザー・ヘッド Ireizā Heddo?), is a Pro Hero and the homeroom teacher of U.A.'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 often half-opened black eyes. He is usually recognized for his worn-out appearance,[1][2] often appearing as if he just rolled out of bed. His facial hair remains unkempt and his eyes almost always looked tired and flat.

Shota sports a ragged 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 yellow goggles underneath his scarf for when he needs to use them in battle.[1]

After being heavily injured by Nomu, Shota's entire face and both of his arms were completely covered in bandages.[3] Once these bandages were removed, Shota reveals a deep scar underneath his right eye.[4]

His formal attire for press meetings and meeting with parents of his students includes a black suit, blue tie, and white dress shirt. While in this attire, his hair is well-groomed and held back in a low bun at the base of his neck.

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 mostly reserved man who has lofty expectations of his students. He is primarily moved 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, exhorting very little energy in most situations, preferring to take naps in his sleeping bag instead.[2][5]

Sleeping bag

Shota's tendency to lay inside his sleeping bag.

As a teacher of high expectations, Shota is known to expel students who he feels are not suited for U.A. High, although it is noteworthy that he has not expelled any students from Class 1-A yet despite being well-known for doing so.[6] He can be rigid and strict when necessary, and also has little tolerance for disobedient behavior. 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.[7] He also blatantly stated that he did not believe Izuku Midoriya could become a hero when they first met.[1] 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'.[8]

Shota personality

Shota's impression on his students.

Despite his apathetic traits, Shota genuinely cares about his students and will go to great lengths to protect them as he saved Tsuyu Asui from Tomura Shigaraki, in spite of his grievous injuries. [9] 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.[10] Recovery Girl even implied that he allowed himself to be captured by Momo Yaoyorozu during her End of Term Test in order to boost her confidence.[11]

Shota is not without his basic human emotions, as 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 was once Shirakumo, 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. This was seen when Shota strangled Kyudai 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.

Shota has shown on several occasions that he is not completely devoid of joy or humor. Despite his personality, he often grins whenever he is impressed by one of his students[1][11] or after he tricks them with one of his 'rational deceptions'.[6][8]


Overall Abilities: Eraser Head has demonstrated incredible combat prowess and ingenuity that makes him one of the most formidable teachers and Pro Heroes at U.A. High School. Even without his Quirk, Eraser Head relies on his hand to hand skills, excelling in close quarters combat. He uses his combat skills in conjunction with his capturing weapon, and is very strong and quick when doing so. He effectively held his own while surrounded and outnumbered dozens to one, evading multiple attacks from villains of various sizes before restraining them and sending them flying with calculated counter attacks. He was even able to nearly defeat Tomura Shigaraki, a highly capable villain, before Nomu intervened and overpowered the Erasure Hero. Other than Tomura, Eraser Head can effectively fend off high level villains such as Vanguard Action Squad members, Dabi and Himiko Toga, albeit with some difficulty.

Keen Intellect: Shota 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. He uses goggles in conjunction with his Quirk to prevent enemies from figuring out who he's looking at. He also quickly creates strategies for dealing with different types of enemies, even those who are immune to his Quirk.


Shota erasure

Shota's eyes while using Erasure.

Erasure ( (まっ) (しょう) Masshō?): Shota's Quirk gives him the ability to nullify another person's Quirk by looking at the user.

After sustaining grievous injuries at the U.S.J., Shota can't use his Quirk for as long and must rest longer between erasures.[11]

While powerful, this ability has many drawbacks:

  • Erasure deactivates if Shota blinks or if his line of sight is obstructed.
  • His Quirk gives Shota bad dry eye, forcing him to blink more often when he uses the power continuously.
  • Mutant-Class Quirks are immune to erasure.
  • 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.

Eye drops: Shota carries a small green case of eye drops with him. He uses them to treat the dry eye caused by his Quirk.

Capturing Weapon (捕縛武器 Hobaku Buki?): Eraser Head's weapon of choice is a cloth made from steel wire alloy woven with carbon nanofibers. He uses these restraining bonds to capture and immobilize targets. It is often used with his Quirk, and can be used to counter enemies who are immune to erasures. He states that it took him six years to master using his binding cloth.

Goggles: Eraser Head can be recognized by the gold goggles he wears around his neck, hidden by his scarf. He only puts them on in a fight because they complement Shota's Quirk. The goggles hide his line of sight, preventing enemies from effectively determining whose Quirk has been erased. He got these goggles from a friend from his school years.

Caltrops: Eraser Head used caltrops in the practical battle against Team Todoroki & Yaoyorozu. They were effective when used in combination with the capturing weapon. After suspending Shoto in mid-air with the capturing weapon, Shota threw caltrops beneath Shoto so he couldn't land safely in case he escaped his restraints. 

Knife: Eraser Head has a large knife. It's useful to cut off his Capturing Weapon should it become stuck to something. He can also use it in combat.
