This article contains minor spoilers for My Hero Academia Seasons 1-7, which are currently available for streaming on Crunchyroll.
All For One: An Unyielding Villain
In the realm of shōnen storytelling, the impact of a series often hinges on the effectiveness of its final boss.My Hero Academia has introduced audiences to a diverse array of formidable villains, yet none have evolved more significantly than All For One, the show’s primary antagonist. His character has only intensified over the course of the anime.
Initially introduced as a mere disembodied voice at the end of Season 1, All For One has spent considerable time imprisoned. However, he has shown an uncanny ability to manipulate events from behind bars, contributing to the societal chaos seen throughout Seasons 6 and 7, not to mention his eventual escape.
All For One’s Disturbing Presence

For a substantial portion of the early seasons, All For One’s true intentions are shrouded in mystery, only hinted at until they become increasingly apparent. This narrative strategy is effective, as he initially appears as a past adversary of the now-legendary All Might, referenced in stories relayed by supporting characters.
Even before becoming a direct antagonist, All For One’s ominous presence loomed over the storyline, instilling fear. A prime example of this is the Kamino incident in Season 3, where his imposing theme and understated appearance combine to create an operatic sense of dread, enabling him to dominate every scene.
A Demonic Persona

His mask and breathing device complement a costume that exudes both elegance and menace. In addition to his unique design, All For One’s character reflects My Hero Academia’s tendency toward body horror, featuring a disfigured visage that accentuates his sinister nature. This visual impact is bolstered by the power of his voice.
Voiced by Akio Otsuka in Japanese and John Swasey in English, All For One’s tone encapsulates a chilling blend of age and malice. Otsuka’s interpretation conjures an impression of sadistic glee even when facing opposition, making him an eerily captivating character. The casting of Hiroshi Kamiya, a talented actor with a mesmerizing voice, was a strategic choice when All For One’s form underwent a transformation in Season 7.
All For One’s Legacy of Chaos

All For One’s lethal capabilities stem from more than just his quirk-stealing prowess. While the ability known as “All For One”primarily serves as a narrative function to confront the series’ formidable heroes, his true strength lies in psychological manipulation.
His previous defeat came at a significant cost, triggering a cascade of events including All Might’s quest for a successor to inherit One For All. All For One’s influence extends to the transformation of Tomura Shigaraki and the tragic fate of Endeavor’s son, Toya, into the villain Dabi. These orchestrated tragedies create profound emotional impacts on the heroes, exemplifying All For One’s role as a remorseless manipulator.
A Final Confrontation in a Fragile World

Since the Hero Killer saga in Season 2, My Hero Academia has explored not only heroism but also the shortcomings of its society. Villains like All For One subvert the traditional notions of villainy, emerging more as opportunists against a failing system. While the majority of adversaries have roots in societal failings, All For One stands apart as a malevolent force willing to exploit the world’s vulnerabilities.
While complex villains often elicit sympathy, All For One embodies the embodiment of pure evil. His character provides depth in a classic manner, demonstrating that not all villains need relatability to effectively engage the audience.
All For One: The Epitome of a Final Boss

As the Final War commences, All For One’s ambitions are laid bare. His desire for world domination may seem archetypal, yet it’s his rhetoric that sets him apart. His goal is not merely control but rather to instill dread and undermine the hopes of those beneath him.
In this world, with its infinite number of cultures and values, the action that makes everyone frown and hate you – it’s something that keeps people from the future they imagine for themselves. That’s why I’m going to keep everyone in the world from their futures.
All For One’s influence tortures the psyche of those affected by tragedy, making it challenging to envision a positive future. His malevolence manifests during a period when uncertainty about the future permeates society, rendering him an especially relevant antagonist.
This stark opposition to the theme of generational progress in My Hero Academia emphasizes All For One’s effectiveness as a villain, setting the stage for an epic confrontation when the series returns for its highly anticipated final season later this year.
