My Hero Academia Season 8 starts the Final War Arc with a central confrontation between All Might and All For One, the battle fans have been longing to see. The anime is an adaptation of the conclusion of the manga by Kohei Horikoshi, which includes the 40th to 42nd volumes (chapters 399-431), and Season 8 premieres with a faithful translation of all the accumulated tension into animation. This is not merely a physical fight but a symbolic one, as it is the final act in the journey of All Might and the legacy of heroes within the My Hero Academia universe.

Spoiler Warning: The discussion below features spoilers of the ending of the manga of My Hero Academia, such as the final battle between All Might and All For One.

All Might does not quite overcome All For One by re-taking One For All, but he does strike a fatal blow and helps bring about the defeat of All For One, with the assistance of allies and tactical sacrifice. He battles without his Quirk, in mechanical support armor, and still finds a place to stand against his long-time nemesis, which influences the final result.

In My Hero Academia Season 8, All Might goes into the battle without One For All, since the remaining traces of One For All have been used up in other fights, particularly the fight in Kamino. He wears a powered mechanical suit (sometimes referred to as “Armored All Might”), which uses support equipment to offset his missing strength. His plan is not to win Quirk power back but to stand, to buy time and inspire heroes and civilians in his last battle.

The fight starts with the aggressive attack by All Might on All For One, even when he is in a weakened state. He relies on Blackwhip cables, Tentacole arms, soundwave modules, and other support equipment to move, restrain, and strike. All For One repays with several Quirks simultaneously and tries to beat All Might with his brute strength. The villain also possesses regeneration and combined Quirk attacks to overcome the defense of All Might.

Later on, All Might is severely damaged in the fight. His suit has been torn in fragments, his body pulled over injuries both old and new. The utility systems of the Armor are stretched to the limit. Nonetheless, All Might succeeds in delivering a decisive blow with the help of Shoot-Style Smash (or any other similar stylized finishing moves that are modified to suit his present weakness). This blow asserts itself against the direction of All For One, and impairs him, though it does not renew the original power of All Might.

All For One is eventually overpowered, although not by All Might himself. Deku and other heroes have significant roles in the completion of the battle. The action of All Might, even though of heroic importance, is a subset of a greater alliance that entails sacrifice, collaboration, and the legacy he created.

My Hero Academia Season 8 is a title that highlights finality as the conclusion of a mentor trope of the main character, the hereditary transfer of authority, and resolution. It not only adapts this battle, but also the epilogue of the world after the war. Although All Might does not defeat All for One, his triumph is survival, driving back All For One, and showing what being a hero is without Quirk power.


To sum up, All Might in My Hero Academia Season 8 does not necessarily defeat All For One in the strict sense of ending the battle. However, he does deliver a critical strike and significantly contributes to the villain's ultimate defeat. It is not only his fight, but also one bound to Deku and other heroes, and thus, a real culmination of the series' themes of legacy, sacrifice, and heroism without power.
