The League of Villains is a clandestine criminal organization dedicated to dismantling Japan's established hero society.
Founded under the influence of All For One, the League serves as the foundation for a new generation of villains seeking to overthrow the system maintained by professional heroes.
Its public-facing leader is Tomura Shigaraki, a dangerous young villain possessing the destructive Quirk Decay.
Although Tomura appears to control the organization, its true origins and resources are connected to All For One, the legendary criminal mastermind who once ruled Japan's underworld.
The League's primary objective is the destruction of All Might, whose existence as the Symbol of Peace represents everything its members seek to overthrow.
Though initially small, the organization possesses resources and connections far beyond those of ordinary criminal groups.
For generations, All For One controlled much of Japan's criminal underworld through an extensive network of loyal followers.
However, the rise of All Might shattered his empire.
The Symbol of Peace systematically dismantled criminal organizations, defeated powerful villains, and eventually confronted All For One himself.
Their devastating battle left both men critically injured.
Although All Might believed his enemy dead, All For One survived and withdrew into hiding.
Unable to operate openly, he began preparing a successor who could eventually destroy the heroic society that had replaced his former empire.
That successor was Tomura Shigaraki.
Under All For One's guidance, the League of Villains was established as a new criminal organization intended to unite dangerous individuals beneath a common purpose.
Real Name: Tenko Shimura
Quirk: Decay
Tomura Shigaraki is the young leader of the League of Villains.
His Quirk, Decay, allows him to disintegrate objects and living beings through physical contact.
Originally named Tenko Shimura, Tomura experienced a traumatic childhood that culminated in the destruction of his family.
Following this tragedy, he was taken in by All For One, who nurtured his hatred toward heroes and society.
Unknown to Tomura, he is the grandson of Nana Shimura, the seventh wielder of One For All and All Might's deceased mentor.
All For One deliberately exploited this connection, transforming Nana's descendant into a weapon against her successor.
Tomura possesses immense destructive potential but remains emotionally unstable, impatient, and inexperienced as a leader.
His hatred of All Might is particularly intense.
He believes the Symbol of Peace has created a society that ignores suffering while pretending that everyone can be saved.
To Tomura, destroying All Might is the first step toward destroying the entire system.
Quirk: Warp Gate
Kurogiri serves as the League's second-in-command and Tomura Shigaraki's primary caretaker.
Unlike Tomura, Kurogiri is calm, polite, intelligent, and methodical.
His Quirk allows him to generate portals through a dark, mist-like substance, enabling rapid transportation across considerable distances.
This ability makes him essential to the League's operations, allowing villains to move between locations without conventional transportation.
Kurogiri manages the organization's hidden headquarters, assists with recruitment, and supervises Tomura's activities.
However, his true nature is far more disturbing.
Kurogiri is an artificially modified human created through experiments conducted by Dr. Kyudai Garaki.
His body originated from Oboro Shirakumo, a deceased U.A. student and former friend of Shota Aizawa and Hizashi Yamada.
This information remains completely unknown to the public and nearly everyone associated with U.A.
Quirk: All For One
Although Tomura leads the League, All For One remains its true benefactor.
Following his defeat by All Might, the Demon Lord began operating from a hidden location, relying upon specialized medical equipment to survive.
Through his criminal connections and enormous collection of stolen Quirks, he provides the League with resources, guidance, and powerful assets.
All For One views the organization as an opportunity to cultivate Tomura into a villain capable of surpassing previous generations.
He encourages Tomura to make decisions, experience failure, and develop his own leadership abilities.
However, these apparent freedoms conceal All For One's deeper ambitions.
The League is not merely a criminal organization.
It is an instrument through which All For One intends to reclaim his influence over society.
Dr. Kyudai Garaki is a brilliant scientist and longtime associate of All For One.
Specializing in Quirk research, biological modification, and artificial enhancement, Garaki secretly supports the League through advanced experimentation.
His most disturbing creations are Nomu, artificially modified humans engineered to withstand multiple Quirks.
These creatures possess extraordinary physical capabilities and can be equipped with combinations of stolen abilities.
Garaki's experiments provide All For One with weapons capable of challenging even powerful Pro Heroes.
His involvement remains concealed from ordinary League members and the public.
The League maintains a hidden headquarters disguised as an ordinary bar in Kamino Ward.
The establishment provides a meeting place for Tomura, Kurogiri, and their criminal associates.
Kurogiri typically manages the bar, using it as a secure location for planning operations and communicating with their mysterious benefactor.
The headquarters also serves as a gathering point for potential recruits.
Its unassuming appearance allows the organization to operate without immediately attracting attention.
The League seeks individuals who harbor resentment toward professional heroes and modern society.
Potential recruits include violent criminals, social outcasts, dissatisfied Quirk users, and individuals who believe the hero system has failed them.
However, not every member shares the same motivations.
Some desire destruction.
Others seek freedom, revenge, recognition, or acceptance.
Tomura's hatred provides the initial direction, but the League has not yet developed a unified political ideology.
Its members are connected primarily by their willingness to oppose established society.
This lack of cohesion makes the organization unpredictable.
Among the League's greatest secret resources are the Nomu developed through Garaki's research.
These artificially modified humans possess enhanced bodies and multiple Quirks.
Some are engineered specifically to counter particular heroes.
Unlike ordinary criminals, Nomu can endure devastating injuries and continue fighting with little regard for their own survival.
Their existence provides the League with a potential military advantage far beyond its limited membership.
One particularly powerful Nomu has been designed with the intention of challenging All Might himself.
The League's immediate ambition is to destroy All Might and expose the weaknesses of modern hero society.
Tomura believes that eliminating the Symbol of Peace will create widespread fear and undermine the public's confidence in professional heroes.
Beyond this goal, the organization seeks to expand its influence, recruit powerful villains, and destabilize the institutions responsible for maintaining public order.
U.A. High School represents a particularly significant target because of its reputation and direct connection to All Might.
An attack against such a prestigious institution would demonstrate that even the most heavily respected symbols of hero society are vulnerable.
However, Tomura's ambitions remain immature compared to the far-reaching plans of All For One.
In 2171, the League of Villains remains a relatively small and largely unknown criminal organization.
Tomura Shigaraki leads its emerging operations, supported by Kurogiri and secretly funded by All For One.
Dr. Garaki continues developing Nomu through hidden experiments.
The League has not yet gained the large following or widespread notoriety necessary to challenge Japan's established hero system openly.
Meanwhile, All Might remains the Symbol of Peace, and U.A. High School continues educating the next generation of aspiring heroes.
Unknown to the public, a dangerous organization is gathering strength beneath the surface of society.
Its leader dreams of destruction.
Its benefactor dreams of domination.
And its existence threatens the peaceful era that All Might sacrificed so much to create.
The League of Villains has only begun to gather.
Its war against hero society has yet to truly begin.
