Endeavor, Hawks & Trainees vs. All For One is a battle taken place during the Final War as Heroes Endeavor and Keigo Takami, with assistance from several trainees, face against the Villain All For One.

Prologue
In order to defeat the Paranormal Liberation Front once and for all, the Heroes determine their first priority is to separate them, specifically Tomura Shigaraki and All For One, so that they can not assist each other.

To deal with All For One, Endeavor is chosen to take the lead in the assault. While his preferred choice was to handle Dabi, everyone else agreed that he should be the one to face All For One, due to being one of the strongest Pro Heroes left fighting, and with All For One as the second biggest threat behind Tomura, they need his firepower.

Hawks joins him for the battle, with their plan being to have the confrontation just between the three of them, allowing them to keep the fighting in the air away from other people who could potentially have their Quirks stolen by him. Their primary objective during the battle is to destroy All For One's life support mask, as using the footage from the Assault on Tartarus, they discovered All For One still requires it to survive, and destroying it will take him out of the fight.

To accomplish all of this, the battlefield they choose is the former ruins of the Gunga Mountain Villa. Aware that other Villains will be caught up in their initial separation, a group of other Heroes, including Kamui Woods, as well as several U.A. students, will accompany Endeavor to the Villa to deal with the stragglers on the ground while he and Hawks deal with the major threat.

On the day of the operation, All For One contacts his mole, Yuga Aoyama, using him to lure Izuku Midoriya out into the open so that he can steal One For All, using a Lie Detection Quirk to make sure Yuga doesn't attempt to deceive him, and the Search Quirk to make sure no other Heroes are nearby. However, the Heroes are successfully able to trick All For One out into the opening, summoning the might of the Front, while the Heroes are warped to the battlefield thanks to Kurogiri's Warp Gate.

Right before the fighting can start, All Might activates the Troy defense system, entrapping all the Villains in cages. All For One is initially confused, due to how easy it is for them all to break out of them, however quickly deduces their true purpose, and the Heroes' plan. Sure enough, after just a few seconds, the Villains break out, but that is enough time for the Warp Gates to be summoned, and allow the Heroes to push the respective Villains into their correspondent portals.

All For One and a group of miscellaneous thugs, as well as one Near High-End Nomu are sent to the Gunga Mountain Villa, where Hawks is already there waiting, immediately striking All For One with one of his feathers, though the attack is ineffective due to All For One's mask. After Endeavor states that they are aware of the limitations of All For One's Warping Quirk, meaning he'll be unable to reach Tomura, All For One comments on the pros and cons of their "divide and conquer" plan, particularly the risk of having Izuku face Tomura, and the "cruelty" of having his two sons fight each other.

While the fighting amongst the Heroes and Villains continue on the ground, Endeavor and Hawks are able to keep All For One busy in the air, when they receives word that Shoto has successfully defeated Dabi in battle. All For One notices Endeavor's reaction, wondering if it is a face of affection or grief, leading Hawks to remind Endeavor not to listen to his mind games. As All For One readies his Quirks, continuing to taunt them for their decisions, the three begin their fight proper.

Battle
Endeavor and Hawks charge their way forward, All For One lamenting how rude they are for ignoring him. He fires several Razor Blades toward the Heroes, which Endeavor blocks with his Hell's Curtain. Hawks shoots several of his feathers through the fire toward the mask, which All For One is easily able to dodge, using an Ooze Quirk to stop Hawks in his tracks from attacking him from behind with his two swords. He states that the obvious tactics are shameful from the "man who used to be too fast", able to tell that his wings were never able to fully recover, even with Recovery Girl's help, forcing him to rely on prosthetics to keep him up to this speed. Hawks simply smiles and responds that it means they're both crippled now.

Hawks then flies out of the way as Endeavor appears, assaulting All For One with his Vanishing Fist, which the Villain attempts to defend. He thinks about how the intense heat of Endeavor's Hellflame passes right through his Hardflame Fan, that he can't reflect it with Impact Recoil, and that Hawks isn't giving him an opening to strike back. To make up for this, he decides to restart his mind games, telling Hawks their timing isn't exactly right and that Endeavor's heart doesn't appear to be in it.

Endeavor doesn't bite the bait, revving up another Vanishing Fist as he tells Hawks they're landing damage on it, with him not having a Super Regeneration-like ability. All For One continues to taunt while defending from the blows, pointing out all the Heroes, including students, fighting their hardest on the battlefield, while Endeavor seems to have his mind on other things, asking if he's delighted his "masterpiece" cleaned up his "failed experiment".

This starts to get at Endeavor as he responds back to shut up, with Hawks trying to warn Endeavor not to fall for his provocations like what happened to All Might during the Kamino Incident. His words fall on deaf ears as Endeavor charges forward toward All For One, as the Demon Lord reveals that he's always had an eye on his twisted longing for power, and that he can't help but "sow seeds" whenever he comes across fertile ground. He then unleashes his bombshell, asking if he never found Toya's body, revealing his role in his son's disappearance.

The revelation completely shocks Endeavor, while a following Hawks is also surprised that he had such a nasty card to play. Thinking about how hard he has been trying to atone, and knowing that in his current state he would be unable to fight and beat Dabi, he has to be there to support him. Hawks cries out to Endeavor to keep a cool head as it's his duty to take down All For One, but Endeavor is unable to listen, fuming with rage as he cries out the villain's name in anger.

All For One is able to take advantage of his lapse in focus, gleefully stabbing him on the side with his Quirk combination arm, as the Flame Hero begins to fall to the ground. Hawks tries to save him, but All For One raises both his hands toward the Winged Hero, asking if "Nagant's Replacement" can dodge his attack at that close of range. Hawks realizes he's unable to dodge, but is able to send some of his feathers toward Endeavor to help him.

Just then, Hawks is saved from All For One's Air Cannon blast by a Heartbeat Wall courtesy of Earphone Jack, riding Tsukuyomi. The two try to readjust their bearings while flying in the air, while Hawks cries out to the students that it's too dangerous for them to be in the fight. Tsukuyomi yells back in response that even though he's not in Endeavor's league, he's still capable of teammwork with his mentor.

In response to this new development, All For One addresses the "gnats around One For All, and how in the comics he used to read they had "jobber characters" who only existed so the Demon Lord could show how strong he was. Earphone Jack confidently responds back that he should wait to save the line until he's won the fight.
