Hero Killer: Stain, real name Chizome Akaguro, is an antagonist in the anime My Hero Academia.

Background

Stain is an infamous ex-vigilante and villain. He is most notably known for killing many pro-heroes (hence the name Hero Killer) in order to make the world more just, at least in his eyes.

As a teen, Stain was inspired by All Might to become a great hero. He quickly joined a hero training course, but became discouraged when most children were joining for their own desires, rather than help others. This upset him deeply, as he felt it destroyed what it means to be a hero, and he dropped out. He began preaching his ideology about heroics, but went unheard and ignored. Because of this, he trained himself in the art of killing, in order to force his "Revival of Heroics" upon the world.

Powers and Abilities

  • Bloodcurdle: Chizome's Quirk allows him to paralyze his target upon tasting a sample of their blood. The amount of time a victim remains paralyzed depends on their blood type; in ascending order from shortest to longest duration, they are: O, A, AB, and B. The maximum amount of time that anyone can be paralyzed is eight minutes. The Quirk was taken by All For One at the same time as his death.
  • Immense Speed: Stain's most notable ability was his unmatched speed. He evaded Tenya's high-speed kick when they first clashed and partially blocked Tenya's "Recipro Burst" during the ensuing battle, and Tenya is revered as U.A.'s fastest student. Due to the Hero Killer's formidable reaction time, Shoto Todoroki could not land a single strike on Stain, even using fire and ice attacks. Shoto mentioned that Stain is so fast that he could not even consider running away as an option. Despite Stain's incredible speed, however, he was unable to evade the combined, high-speed assault from Tenya's "Recipro Extend" and Izuku's Full Cowl that was used in tandem with a 5% "Detroit Smash", though Shoto claims this was partly due to Stain getting desperate knowing several pros would soon be arriving on the scene.
  • Enhanced Strength: Stain had considerable strength, as it was enough to slice through many of Shoto's ice attacks cleanly.
  • Immense Stamina: Stain had a high pain threshold, as shown when he takes a direct blow from Izuku's 5% Detroit Smash to the head and remains primarily unfazed. After battling against the trio of U.A. Students and killing the Winged Nomu, it was revealed that Stain's lungs were perforated by his broken ribs, but he could remain standing even after falling unconscious. Stain was also capable of swimming from Tartarus back to the mainland. After being thrown through several city blocks by All For One's additional appendage, Stain remained conscious long enough to give his final encouragement to All Might before meeting his end and losing his Quirk.
  • Enhanced Smell: Despite his mutilated nose, Stain had an extremely keen sense of smell. While confronting All Might in Kamino he was able to memorize the retired hero's scent while in close proximity with him. Later on, during All Might's final battle against All For One, after smelling some stray blood from the fight, he was able to tell through his nose that the blood was All For One's and not All Might's.
  • Tactical Intellect: Stain is shown to possess some analytical skills. Stain noticed all the chaos caused in Hosu City and correctly deduced that Tomura Shigaraki and the League of Villains were behind the attack. While engaged in a battle against Shoto, Stain pointed out that the hero relied too much on the destructive power of Half-Cold Half-Hot Quirk, making him predictable and easy to exploit in battle. Stain also carried a spare hidden knife to surprise his opponents should the Hero Killer have been deprived of his weapons.
  • Indomitable Will: Stain's ridiculous force of will seems to impact the psyches of others, even during combat substantially. He was able to paralyze several top heroes, including a seasoned veteran like Gran Torino and the No. 2 (now No. 1) Hero Endeavor, with fear despite having suffered severe injuries. He also forced many heroes to reconsider their actions and beliefs, even during combat. Even after his capture, footage of his speech to the heroes inspired many criminals and vigilantes into action bolstering the ranks of the League of Villains considerably.

Equipment

  • Weapon Arsenal: Before being arrested, Stain carried various weapons with him:
    • Katana:
    • Five Daggers:
    • Throwing Knives:
    • Toe-Spiked Boots:
    • Folding Knives:
    • Small Machete:
  • Glider: A transportation device that allows him to fly through the air. He used it to fly above the battlefields during the Final War, and to reach All Might's location to aid him.
