Decay (崩壊 Hōkai?): Tomura's Quirk allows him to disintegrate whatever he touches with all five fingers. It will take effect whether the target is organic or not. The disintegration spreads quickly and will spread through the victims whole body if they don't amputate the decaying body part. His Quirk can even spread beyond what he's touching, allowing him to disintegrate large groups of enemies instantly.
Because the Quirk has to touch a solid object in order to be activated, it is possible to counter it through manipulation of fluids or particles, such as Snatch's sand body.
During his battle against Re-Destro, Tomura's Quirk underwent an Awakening that allows him to decay his targets without needing all five fingers. This was displayed when Tomura used his two remaining fingers to partially decay one of Re-Destro's fingers after the latter destroyed three of Tomura's fingers on his left hand, albeit it was much slower and weaker compared to when Tomura uses all five of his fingers.

Overall Capabilities

Tomura is known to be one of the most dangerous villains in Japan, contending with Pro Heroes in combat thanks to his physical and analytical skills. As the leader of the League of Villains, Tomura has total command over his powerful subordinates. During the U.S.J. Incident, Tomura had the mettle to briefly take on the formidable Pro Hero Eraser Head, and successfully use his Decay Quirk on the Erasure Hero's right arm. Tomura was even confident that he could take down Izuku Midoriya, Shoto Todoroki, Katsuki Bakugo, and Eijiro Kirishima, four highly capable U.A students, although at the time, didn't know the full extent of the quartet's abilities. Tomura was capable of battling Gigantomachia for half a month, not giving up until he is able to make the behemoth submit. When he faced Re-Destro, and his left hand was partially destroyed, Tomura's prowess had been suddenly enhanced to levels beyond his natural parameters. According to Re-Destro, if Tomura had his newly increased parameters during the Kamino Incident, he would've easily decayed at least 1 of the Pro Heroes present. After a fierce battle he was not only able to defeat Re-Destro but gained control of the latter's army, as well as tame Gigantomachia with his accomplishment.

Enhanced Strength: Tomura seems to be stronger than his build suggests, capable of holding Izuku by choking him with only four fingers while his victim displayed visible difficulty in trying to fight back.

Enhanced Durability: Tomura was able to take a point-blank blast from Katsuki's Explosion Quirk, sustaining little to no damage. He was even capable of battling Gigantomachia for half a month, and withstand the behemoth's attacks.

Enhanced Speed: Tomura appears to be able to move very quickly, which helps him to touch his targets and affect them with minimal contact. He was able to appear before Tsuyu Asui in an instant and see Izuku after the latter had jumped at a speed that rivaled All Might's, immediately reacting afterwards. Only All Might himself was too fast for Tomura to track. Even when he was notably exhausted during the battle against the Meta Liberation Army, he swiftly swung himself atop a wall to avoid a massive onslaught of Army members, to their surprise, before disintegrating many of them in an instant. When he battled Re-Destro, he was able to move so fast with minimal wasted movements, that Re-Destro was taken by surprise by the increase in speed he had obtained.

Keen Intellect: Tomura possesses a sharp mind and is analytical, being able to deduce the workings of his opponents' abilities simply by observing them in action. He quickly deduced Eraser Head's weaknesses in combat and took advantage of them. Tomura has a certain skill for unexpected plans, even when his intentions are apparently clear. After battling Gigantomachia for over month, Tomura realized that the behemoth has gotten much slower compared to the League of Villains first encounter with him, and strongly believes that he will soon have Gigantomachia successfully tamed.


Tomura was born under the name "Tenko Shimura" to Nao Shimura and Kotaro Shimura, and had a older sister named Hana Shimura.

When Tenko was a child, he had a fascination with heroes, but his father did not tolerate his acts and often punished him for them by putting him outside. Tenko did not seem to have a Quirk but he suffered from unknown physical changes to his body. However, his mother and grandparents were always there for him and encouraged him, as did his sister who showed him a picture of their father and grandmother, who they learned was a hero.

Unfortunately, Tenko's father discovered this and punished his son, while also shaming heroes for protecting others and abandoning their families. Tenko's suffering was watched by his other relatives, who he begged for help but they could only witness it in horror. While outside, Tenko confided in the family dog of how he hated everyone for leaving him to suffer.

As he was clutching his dog, Tenko's Decay Quirk activated, causing the dog to crumble in his hands. Afterward, Hana came outside to apologize to Tenko for not standing up for him but proceeds to run away in fear after seeing their dog dead next to him. When Tenko tries to reach for her, he ends up disintegrating her by accident.

Tenko's grandparents and mother ran outside to see what was happening and Tenko ended up killing them when his Decay Quirk spread in his panic. When Tenko's father came outside and saw the chaos, Tenko ran to him for help but his scared father would grab some garden tools to protect himself. This time, an enraged Tenko charged at his father with full intent to kill him and touched his face; ultimately the spreading decay ended up destroying the entire house. Tenko would relish in ending his father’s abuse.

After the deaths of his family, an orphaned Tenko was left to fend for himself on the streets. People who passed by never offered to help him, because they assumed that a hero would take care of it, leaving him to be ignored. It didn't help that they were also unnerved by the disturbing look on his face and pretended not to notice him. Tenko began to think this was punishment for his actions, as the memories slowly faded into the recesses of his mind. Eventually, a man named All For One saved him, blaming society for the reason he was not saved sooner.

All For One used this incident as a means of stimulating Tenko's newfound hatred for heroes and began grooming him as his adoptive son. Tenko was given his own room by All For One, and Daruma Ujiko "gifted" the young boy with the disembodied hands of his deceased family members.[3] All For One taught Tenko to embrace the urge he felt whenever he felt it and Tenko did just that by killing two thugs and adding their hands to his look. All For One later renamed him Tomura Shigaraki and raised him as part of the League of Villains, to eventually become his successor of the organization.
