One For All

As a boy, Toshinori Yagi told Nana Shimura he wanted to be a pillar people could cling to. In the present, Shoto and Momo reach safety and phone Izuku. Katsuki rejects the word rescue outright, insisting he only moved so All Might would have room to work, and Izuku wonders whether leaving the fight was right.

All For One needles his enemy about resembling a weak predecessor, baits an angry swing, and blasts him away through an opening. All Might nearly hits a news helicopter before Gran Torino catches him and reminds him that this same goading cost him their last fight. Classmates and teachers watch the broadcast in horror. The villain claims mixed feelings about finishing off hero society himself, given how hard his protégé labored to ruin it, then admits he hates All Might for destroying everything he built. His next shot is aimed at a civilian trapped under rubble, and All Might takes it with his own body.

The impact strips him to his true form on live television. All For One promises to destroy his reputation by exposing the weakness; All Might replies that his heart holds the Symbol of Peace regardless of the shell. The villain plays his cruelest card, naming Tomura Shigaraki as Nana's grandson, and the smile Nana taught him falters as he imagines what she would see.

The rescued civilian tells him to win. Others take it up, then the country, then Izuku and Katsuki screaming at a screen. Resolve restored, he floods his arm with what power remains and tells his enemy that heroes carry too much to lose. Nana's voice returns: recall where he started, and he can push past his ceiling. Gran Torino frets that the punishment has drained both the man and the Quirk. Endeavor and Edgeshot charge in, the flame hero enraged at the sight of that withered body, demanding the number one prove it. Kamui Woods drags the wounded clear; Tiger calls All Might everyone's top hero no matter how he looks.

Annoyed, All For One scatters them and assembles a monstrous arm from stacked Quirks, revealing that he knows One For All has already passed to Izuku and that only embers remain. The two collide. Told he will die full of regret over a student he cannot control, All Might answers that he has to live to scold the boy and do for him what Nana did for Toshinori. He sacrifices his right arm to close the gap and lands a punch that takes more of the mask. Dismissed for a weak, unfamiliar trick, he retorts that his back simply was not in it, gathers the last of the power, and finishes with United States of Smash.

Onlookers chant his name. He bids One For All farewell, holds the muscular form once more, and Gran Torino explains the job is not done: the Symbol of Peace has to restore the public's faith. Rescue crews move in, the villain is taken into custody, and All Might aims a finger at the lens with a parting line, "You're next". The public hears a warning to criminals. Izuku hears an inheritance.

All Might shields a trapped civilian from an air cannon and permanently reverts to his weakened form in front of a live broadcast. All For One reveals Tomura Shigaraki's blood relation to Nana Shimura and that he knows One For All has been passed on to a successor.

Public encouragement restores All Might's resolve. He gives up his right arm to close the distance, then finishes the fight with United States of Smash. With the villain in custody, All Might's televised "You're next" doubles as the handover of his legacy to Izuku.

The forty-ninth episode and the eleventh of season three, concluding the Kamino rematch inside the Hideout Raid arc. Japan saw it on 16 June 2018 and the United States on 11 May 2019, adapting chapters 92 and 93 plus the first seventeen pages of chapter 94, with Odd Future and Update.

The flashback to All Might's conversation with his mentor is moved earlier than its manga placement, and the sequence of Nana explaining how One For All passes from holder to holder for a greater purpose runs longer. The manga has him in tears as he vows to bring the villain down.
