Shota Aizawa

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

During the U.S.J. Incident, he effectively held his own against low-tier members of the League of Villains that surrounded and outnumbered the Erasure Hero, dozens to one. Shota evaded multiple attacks from opponents of various sizes and abilities 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 the U.S.J. Nomu intervened and overpowered the Erasure Hero. Other than Tomura, Shota can effectively fend off high-level villains such as Vanguard Action Squad members, Dabi and Himiko Toga, albeit with some difficulty. He also played vital roles during the Shie Hassaikai Raid and the Paranormal Liberation War, both of which involved large teams of heroes contending with high-class villains, with the latter spectacle involving the suppression of various High-End Nomus and Tomura's enhanced abilities. Erasure is 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. After sustaining grievous injuries at the U.S.J., Shota can't use his Quirk for as long and must rest longer between erasures. After losing one of his eyes in the Paranormal Liberation War, he has now almost completely lost the ability to use his Quirk. 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-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. The Quirk Factor lies within Shota's eyes, so if one or both are damaged or destroyed, he cannot effectively use Erasure.

Toshinori Yagi

Toshinori Yagi also known as All Might , was the former No. 1 Pro Hero who bore the title of the world's Symbol of Peace. He teaches Foundational Hero Studies at U.A. High School. All Might was the eighth holder of the One For All Quirk after receiving it from Nana Shimura. He has since passed the torch to Izuku Midoriya, whom he is training to be his successor. After using up all the embers of One For All to defeat All For One, All Might retired and ended his era as the world's greatest hero. All Might was recognized as the greatest hero in the world. He was the "Symbol of Peace" and such a deterrent against crime that villains were largely discouraged by his presence in society, single-handedly bringing near-absolute stability throughout Japan, a stark contrast to the rest of the world. He was able to defeat All For One, infamously known as the world's most powerful villain, twice; a feat that all the previous wielders of One For All could not.

Despite winning however, All Might suffered a gruesome injury at the hands of All For One that limited his maximum power output going forward, gradually reducing his sheer might and how long he could use his power at all. Even after his Quirk's power was constrained by his injuries, All Might's strength and speed were unmatched. After he passed his Quirk onto Izuku, relying on the residual energy of One For All made his strength and time limit decrease more rapidly. Even so, All Might could still defeat villains on his own that groups of normal Pro Heroes struggled against. By pushing his power beyond its reasonable limits, All Might defeated Nomu, who was created specifically to kill him, with over 300 blows. Against Izuku and Katsuki, who are among Class 1-A's elites, he completely dominated them in their fight, even while wearing high-density weights. Forced to once again break the limiter placed on his Quirk, All Might defeated All For One by using up his remaining reserves of power. Even though he is unable to keep his hero form for more than a few seconds after his final battle with All For One, All Might still keeps a keen intuition and sharp reflexes, which helped him hone his skills as a hero ever since he acquired his powers. This is shown in his observations regarding Izuku's use of One For All, and the fact that he was capable of catching one of Mei Hatsume's "babies" coming in from behind with minimal effort in his true form. Despite his physique in his true form, he is actually quite physically able but isn't as efficient compared to when he is in his hero form. Usage of One For All requires the user to have strong muscles, as One For All is a lot to handle and could cause the user's body to be blown apart if they don't possess the necessary strength of body. Gran Torino said that All Might, in particular, had a strong body that allowed him to master One For All much faster than previous users. One For All Transferred to him from Nana Shimura, Toshinori's Quirk allowed him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to a superhuman level. This resulted in unbelievable levels of strength, speed, agility, and durability. All Might was so proficient with One For All that he was widely known as the world's most powerful person. However, most of the known feats he performed are after he'd been grievously injured by All For One, and after he started the process of transferring One For All to Izuku, so the fullest extent of his abilities are mostly unknown.
