The ultimate villain’s quest for eternal power has shaped the entire My Hero Academia universe—here’s everything you need to know.
My Hero Academia Man Behind the Myth
All For One stands as My Hero Academia’s most terrifying antagonist, a villain whose influence spans generations. Unlike typical anime villains driven by simple motivations, All For One represents the darkest potential of quirk society—absolute power corrupting absolutely.
His presence looms over every arc, every battle, and every hero’s journey. But what makes this centuries-old villain truly unstoppable? The answer lies in understanding both his origin and his obsession with immortality.
All For One’s Powers Explained
According to the official My Hero Academia canon, All For One was born during quirk society’s chaotic early days when superpowers first emerged. While the world descended into lawlessness, he saw opportunity.
The Secret to His Immortality
All For One’s immortality isn’t a single quirk—it’s a carefully curated collection of stolen abilities working in harmony:
Regeneration Quirks: Multiple healing factors stolen from various individuals allow him to recover from catastrophic injuries that would kill normal humans. These quirks work continuously, reversing cellular aging.
Life Force Extension: Certain rare quirks specifically extend natural lifespan. By combining several of these, All For One has lived for over a century while maintaining combat effectiveness.
Body Preservation: When his physical form deteriorates beyond repair, he uses quirks that preserve his consciousness and transfer it to prepared vessels—as seen with Tomura Shigaraki.

Why He Created One For All
The irony of All For One’s story is that his quest for absolute power inadvertently created his greatest enemy. When he tried to control his younger brother by forcing a quirk upon him, the brother’s latent power-stockpiling quirk merged with the given ability, creating One For All—the only quirk he couldn’t steal.
This mistake haunts him across generations. Every successor of One For All, from the first wielder to Izuku Midoriya, represents All For One’s singular failure in an otherwise flawless plan for domination.
His Role in My Hero Academia’s Story
All For One serves multiple narrative functions:
Symbol of Systemic Evil: He represents what happens when power goes unchecked. His influence corrupted hero society from its inception, as detailed by Shonen Jump’s official timeline.
All Might’s Nemesis: Their rivalry defines an entire era. The Symbol of Peace exists specifically to counter the Symbol of Evil.
Shigaraki’s Puppetmaster: The grooming of Tomura Shigaraki shows All For One’s long-term planning and willingness to manipulate even his “successors.”

Can He Be Defeated?
The final arc reveals that All For One’s immortality has limits. Each body transfer weakens him slightly, and the emotional connections he dismisses—bonds between heroes—prove to be tactical disadvantages he can’t account for.
His greatest weakness? Arrogance. Centuries of victories convinced him he’s inevitable, making him underestimate opponents who fight with something beyond power—hope, determination, and unity.
The Legacy of Evil
All For One’s impact extends beyond his physical battles. He shaped hero society’s structure, created the League of Villains, and influenced countless lives across generations. Understanding him is essential to understanding My Hero Academia’s core themes about power, responsibility, and heroism.
FAQs
Q: Is All For One dead in the manga?
A: Without spoiling current chapters, All For One faces multiple “defeats” throughout the series, but his immortality makes permanent death complicated. His legacy continues affecting the story regardless of his physical status.
Q: Can All For One steal One For All?
A: No. One For All can only be transferred willingly. All For One’s quirk-stealing ability doesn’t work on it, which is why he’s obsessed with destroying its wielders instead of simply taking the power.
