All Might

The Symbol of Peace

All Might was, for a generation, the greatest hero in the world — a beacon whose towering smile assured society that everything would be all right. Behind that public image is a man carrying a secret power and a body pushed far past its limits.

One For All

All Might’s true strength came from One For All, a Quirk passed down through generations of successors and stockpiled into overwhelming power. His decision to pass it to a Quirkless boy, Izuku Midoriya, sets the entire story in motion.

A hero in decline

A grievous old wound left All Might able to hold his heroic form for only a few minutes a day, his true body gaunt and failing. The tension between the invincible symbol and the dying man beneath it defines his later arc.

The mentor

Stripped of his power, All Might becomes a teacher, pouring everything he has left into shaping Deku and the next generation. His transformation from the world’s mightiest hero to its most devoted mentor is the emotional spine of the series.
