All For One

All For One surname Shigaraki, is the overarching antagonist of the My Hero Academia manga and anime series. He is the founder and benefactor of the League of Villains. Once Japan's most powerful villain, and All Might's arch-nemesis, his full identity is unknown. His ultimate goal is to steal his little brother's Quirk, One For All, the only Quirk that can oppose him, shaping Tomura Shigaraki into the perfect vessel, before eventually conquering the rest of the world. He was imprisoned in Tartarus after his second defeat at All Might's hands until he escaped several months later, now single-mindedly focused on destroying the ninth wielder of One For All, Izuku Midoriya, to complete his centuries-long plan. All For One is Japan's most powerful villain. Thanks to the Life Force Quirk, All For One is virtually immortal, and has been active since the emergence of Quirks. He has collected numerous Quirks with an extensive range of applications and can combine them as he pleases.

 

This, along with his ability to steal any Quirk from his opponent makes All For One nigh impossible to defeat. The villain will employ any means necessary to hurt his opponent before killing them. Even in his prime, All For One easily defeated powerful Pro Heroes, making himself appear unequaled and unstoppable. The only individuals that can effectively oppose the Symbol of Evil are the inheritors of One For All, a Quirk All For One himself inadvertently created, and the only Quirk he can't steal (though he tried to steal it from Daigoro Banjo and En, twice). All For One sought each One For All user (excluding Hikage Shinomori), and easily killed them by overwhelming them with his barrage of Quirks. However, All For One was unable to steal One For All, nor prevent any of the users from passing the Quirk. Nevertheless, All For One remained unchallenged until the rise of All Might. All Might possessed the necessary strength to challenge All For One, and the two opponents fought a bloody duel. Although All Might sustained crippling injuries, he succeeded in defeating All For One, forcing the villain to rely on life support system. All For One uses his ultimate combination of Quirk to clash with All Might one final time. Six years later, despite losing all his senses and unable to recover from his injuries, All For One was far from weak. He single handedly overpowered Endeavor, Best Jeanist, Edgeshot, Mt. Lady, and Gran Torino with little effort, as well as fight on par with All Might until the hero was exhausted out of his muscle form. With his ultimate Quirk combination, coupled with All Might's declining power, All For One nearly succeeded in killing All Might, but the latter summoned his willpower and used the last of his power to knock out the Symbol of Evil. All For One's Quirk allows him to steal other people's Quirks, leaving them Quirkless, and wield the Quirks as his own. All For One can also redistribute his stolen Quirks to other people. His multiple Quirks grant him a very wide variety of options in combat, and he can combine his stolen Quirks to create compound attacks with devastating effects. However, he cannot steal the original users' Quirk proficiency and is therefore limited by his own skill with his stolen powers. Because of this, he prefers to steal Quirks that rely on raw power, rather than ones that take practice and experience to master. While he can steal any Quirk, All For One's body cannot properly contain Quirks of newer generations, which is the reason why he sought Dr. Garaki's medical research. He also mentions having frequent nightmares where the consciousnesses of the people he stole Quirks from appear before him. Shortly before the Kamino Incident, his Quirk was duplicated by Doctor Garaki and the original version of it was given to Tomura, while All For One kept the copied version. A conscious vestige of All For One remains within the original Quirk and has the capabilities of overriding Tomura's will and control his body, though it is currently unaware how much of a connection the vestige and original All For One have to each other.

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.
