The reign of Japan’s most powerful villain is finally over. In a stunning turn of events, the ancient evil known as All For One has been permanently defeated. The climax occurred during the final war arc of the popular series, My Hero Academia. His end was not at the hands of his arch-nemesis, All Might, but through a desperate, self-inflicted gambit gone wrong.

The confrontation was the culmination of a long and brutal battle. According to a narrative summary from Shueisha’s Weekly Shonen Jump, the villain’s own attempt to cheat death led directly to his ultimate erasure. This pivotal moment marks a significant shift in the series’ final conflict.
Is All For One Dead in My Hero Academia?
The answer is a definitive yes. All For One consumed a powerful “rewind” drug to regenerate his body and return to his prime. This substance, created by his ally Dr. Kyudai Garaki, reversed damage and injuries by making him younger. However, the effect was irreversible and continuously active.
Every injury sustained forced his body to rewind further. The heroes, understanding this weakness, focused their attacks to accelerate the process. Great Explosion Murder God Dynamight (Katsuki Bakugo) delivered a critical series of explosions that pushed the villain past his breaking point.
All For One rapidly de-aged from an adult to an infant, then to a single cell. He ultimately vanished from existence entirely. His vast collection of stolen Quirks dissipated as he disappeared. The villain who terrorized society for generations was erased by his own hubris and a failed scientific experiment.
All For One’s Pathetic End Carries Poetic Justice
The manner of his defeat carries deep symbolic weight. All For One viewed other humans as mere toys for his amusement. He ruled through fear and manipulation, showing no empathy for the countless lives he ruined. His goal was to live forever and dominate all of society.
His end was not a glorious final stand. Instead, he was humiliated, reduced to a helpless state, and erased by a mechanism he himself set in motion. Bakugo, a hero he considered insignificant, was the one to deliver the final push. This poetic justice ensures the villain’s legacy ends not with a bang, but with a whimper.
This conclusion solidifies his fate as one of the most memorable villain send-offs in modern shonen manga. It underscores the series’ core theme that no one, no matter how powerful, is beyond defeat. The heroes’ victory was a collective effort, proving that unity can overcome even the most immortal of evils.
The final death of All For One closes a major chapter in My Hero Academia. His erasure allows the story to focus fully on the remaining threat of Tomura Shigaraki. This decisive outcome provides a deeply satisfying conclusion for fans who have followed the villain’s long and terrifying reign.
Thought you’d like to know-
How did All For One die?
He was killed by the irreversible effects of a rewind drug. Continuous damage from the heroes forced his body to de-age until he rewound past his own birth and vanished from existence completely.
Who actually killed All For One?
While Bakugo delivered the final attack that accelerated the process, All For One’s death was ultimately caused by his own actions. The combined efforts of all the heroes present forced him into a situation where the rewind drug consumed him.
Can All For One come back after this?
His erasure appears to be absolute. The narrative shows him rewinding into nothingness, with all his Quirks disappearing. A return seems highly unlikely given the finality of his defeat.
What was the rewind drug?
It was a chemical created by Dr. Garaki to reverse damage and aging. The major flaw was that its effects could not be stopped once activated, leading to continuous de-aging.
Why is Bakugo’s role significant?
Bakugo’s intervention was the decisive blow that All For One could not counter. It symbolized how the new generation of heroes succeeded where their predecessors had previously failed.
