Template:AFO Synopsis/Final Act

Dark Hero Arc
After leaving Haibori Woods, All For One seeks refuge in a secret underground cave, one of the many safe houses he and Kyudai left behind as a contingency measure. He is greeted by not only a brand-new life support mask to replace his original, but also a drug alongside a pre-recorded message from the Doctor.

It explains how Tomura got ahold of the Quirk-Destroying Drug created by the Shie Hassaikai, which he immediately attempted to reproduce. After finding out it originated from someone's Quirk, he decided rather than focusing on the "Quirk-Destroying" part, he focused on its original Rewind effect during his recreation. He cautions All For One he can only use it once, but that once he's freed, he's sure it'll help him achieve his dream. He ends the message saying that his voice, eyes, and smile bring joy to his heart and he wishes his heart be filled with hate.

One month later, Lady Nagant tracks down Izuku and begins to capture him to execute All For One's orders. In the subsequent duel, Izuku defeats Lady Nagant and requests her to join his cause, only to suddenly have her explode.

As it turns out, All For One had been monitoring the battle, and anticipating Lady Nagant's possible failure, had secretly transferred a self-destruct Quirk, which he had detonated upon sensing her change of heart. He mocks Lady Nagant for being a woeful and pitiful woman, remarking that she was nothing but a tool to achieve ends from everyone, and she should blame her Quirk for her tragedy.

Expecting Lady Nagant to also reveal the location of their proposed meet up, All For One sets up a trap in the former Creature Rejection Clan hideout, leaving behind a pre-recorded message for Izuku to find. In the message, he taunts Izuku for knowing that someone like him couldn't abandon someone like Lady Nagant, adding in that he didn't force her to join him and that it was her choice. He continues on about how those in society who fall are labeled as "villains", and even if one takes pride in their Quirk, if you can't fit into the controlled society, you'll be excluded, citing it as human nature. He concludes stating the more Izuku fights the more his soul will wear down, and reveals that while in prison, he was the one he never stopped thinking about, no longer having any interest in All Might, telling him it's "his turn" as the mansion explodes.

Star and Stripe Arc
After abandoning the Haibori Woods Mansion, All For One and the remnants of the League hide out in a secret cave alcove. While sitting on his own makeshift throne, surrounded by the remaining Nomu, All For One talks to Spinner about how thanks to the escaped inmates, the Heroes and Police have been too busy to put their full focus on them, allowing them to "win" their game of hide-and-seek. Spinner asks why they didn't just leave the country, but All For One says evading everyone was just his first goal, and that he has more planned.

After Tomura's completion, and acquiring One For All, All For One's next main goal is to get his hands on New Order, the Quirk of Star and Stripe, the number 1 Hero of America. He believes that with that power, alongside his own and One For All, he would finally have everything to make the entire world bend to his every whim. However, he is also aware that if Star and Stripe were to collaborate with the Japanese Heroes, especially One For All, then it would be trouble for him.

So, using his connections to the criminal underworld all over the world, he got them to stir up enough trouble so that the nations would have to prioritize their own safety, delaying their arrival to Japan. However, he learns that Star and Stripe will be making her way over to the country soon, and while that would be trouble, he also reiterates that if he can get his hands on her Quirk, nothing will be a problem anymore.

He then turns to Spinner and tells him that after spending his time guarding him, he will be the one to support Tomura in his crusade, referring to him as "one who spins this tale", reminding him of his status as a heteromorph. All For One then proceeds to send the still slightly incomplete Tomura out to battle to face down Star and Stripe.

Meanwhile, within Tomura Shigaraki, the vestige of All For One continues to exert control over Tomura, with the two starting to fuse together into one new being. As a result, "Tomura" now begins to recognize himself as both Tomura AND All For One, with the latter as the more dominant personality.

"Tomura" goes after Star and Stripe and her army of fighter jets using a combination of Radio Waves, Air Cannon, and Heavy Payload, releasing an enormous wave of electric energy toward them. Star uses New Order, which can impose a new rule over whatever she touches and names, to remove the air from 100 metres in front of her, forcing "Tomura" to hold his breath, while All For One thinks about how it's a horrifying Quirk that he really wants.

The jets shoot lasers at "Tomura" from every angle, which he simply uses Reflect and Scatter to shoot back, while his body regenerates. "Tomura" notices the air vacuum has come undone right after Star had used a new rule to catch the laser, wondering if that is the limit of New Order. He stretches his body and blasts his way forward toward her, but she simply jumps forward as well, punching him in the face.

Star talks about when she was originally saved by All Might as a kid and that he inspired her to be a Hero, something that greatly irritates him as no matter where he goes it's always about All Might. Now that she's touched him, Star uses New Order to declare that if "Tomura Shigaraki" were to move even an inch, his heart will stop.

However, "Tomura" thinks about how she fell for his trap, while All For One continues to push his dominance over Tomura, telling him how thanks to his hatred, the process that should've taken 2 months is now at 97-98% in just over one. He gleefully tells Tomura to let his hatred flow to deliver them to their glorious future, while the resistances permeate to the outside, with "Tomura" suddenly growing long hair and exploding.

Regaining back some control, All For One through Tomura deduces exactly how New Order works. He was able to notice some of her limitations, like how while there's no limit to incapacitating someone, it can only power up a body to a certain amount. He also figures the rule can't arbitrarily involve things she hasn't touched.

He realizes the true utility behind the Quirk is it has the most freedom of control with nonliving things, as when it comes to naming a living thing, both targets have to have the same sense of understanding. The reason Star's declaration didn't work on him was because "Tomura" isn't sure of his true identity, whether he's "Tomura Shigaraki", "All For One", or even "Tenko Shimura", however for inanimate objects with no sense of self, Star's one-sided understanding is enough to enforce the rule. Thinking about all the potential tests for it just makes the Quirk even more irresistible to All For One and want it even more.

After being jostled off the plane he was just standing on, "Tomura" lands back on the flying Nomu, when the two are suddenly blown far away by a giant air visage of Star and Stripe, and proceed to be pinned downwards into the ocean with a giant laser sword.

"Tomura" realizes that something big is coming, and that Star is only using the laser sword to stall, so as the dangerous Tiamat missiles arrive to finally put an end to "Tomura", he uses the Nomu to distract the pilots, while he uses Decay to dig underground, avoiding most of the brunt of the missiles and barely surviving.

He emerges from the cracked hole, stating to them all that he was only just playing along with their game, and if it was anyone other than him they would've been done for. He proceeds to Burst his way forward from jet to jet, gloating how "me and myself" will make better use of her resources. One of the pilots tells Star to try and end them quickly while he's on top of the jets, but Star is unable to do so, allowing "Tomura" to jump and grab her face.

All For One within Tomura thinks about how he knew facing Star and Stripe with the incomplete body and without One For All was a gamble, but thankfully has finally paid off as he begins to steal New Order, while simultaneously Decaying Star. The Hero uses the Quirk to try and halt the Decay, but only succeeds in delaying it due to reaching the cap of her strength. Successfully obtaining New Order, All For One calls Star an idiot for trying to protect herself, and thinks back to Yoichi, and when they used to read comics, with now gaining the Quirk being just one step closer to his dream.

However, before he can make use of it, the vestiges of Tomura and All For One are faced against a vestige of Star and Stripe, who's presence causes "Tomura" to internally explode in the real world. As it turns out, Star had used New Order in order to declare that the Quirk would revolt against other Quirks. A gigantic Star and Stripe begins to pound away at all the vestiges, including the ones of the stolen Quirks, causing All For One to curse Star's name.

All For One as Tomura laments to himself that he can only steal or bestow Quirks, but not dispose of them, and desperately tries to find someone he can force New Order onto to stop the Quirks from rebelling. Instead, the pilots continue to fire at "Tomura" with their laser barrage, while inside the Star vestige destroys the Reflect Quirk. All For One once again angrily curses Star and Stripe as "the spectre of All Might."

"Tomura" takes the Wing Quirk from the remains of the Nomu and desperately escapes the battlefield, intending to find someone to pass on New Order too, once again cursing All Might's existence, taking off into the sky. He crashes in on the hideout of prison escapee, Kashiko Kashi, touching his face planning to take his Quirk to make him Quirkless, so he can safely transfer New Order without it revolting, allowing him to preserve it.

However, as he's about to, the Star and Stripe vestige mocks him, stating that thanks to all the Quirks she revolted against, it has resulted in the destruction of the Quirk itself. As she starts to fade away, she declares even though she wasn't able to kill him, as long as people are willing to stand up to save each other, the will of heroism shall be passed on, and will put an end to him. All For One angrily balks that the winner is the one who lives the longest, as the ghost finally vanishes.

U.A. Traitor Arc
"Tomura" returns back to the League's secret base, screaming over in pain. All For One tells him to calm down, since their Quirk Factors are damaged and need to heal. However, "Tomura" just keeps yelling obscenities, and that as long as people remember All Might, he'll never know peace. All For One notes how, since their minds have fused, he shares "Tomura"'s hatred, telling him even though they couldn't steal New Order, now that they've removed their greatest obstacle, they just need to take it easy for now.

He tells the League to remain on standby for a bit longer, but Dabi responds against this idea, saying how he can't stand the sight of still seeing his dad flying around. All For One tells him that while they are very alike, they have one crucial difference. While Dabi may have only one goal firmly in his mind, he's planned out many different routes over the decades, all to eventually reach his final goal. He tells him while they must wait for Tomura's body to be perfected again, now that Izuku has returned to the fortified U.A., he mentions the other thing that Dabi lacks: "friends to spare".

He promptly goes to contact the Aoyamas once again, with the order for Yuga to isolate Izuku somewhere so they can get him. Dabi asks All For One whether it'll be a problem if his "friends" get caught, but he simply says it won't be at all. If his friends succeed, he'll be rejoiceful, but if they fail, it's a just a brief disappointment before moving on to the next plan: his "friends" are merely just "disposable tools" that he wants to gleam the most amount of excitement as they can.

Sometime later, All For One sees Spinner checking in on Tomura's progress, which has turned him into a monstrous mutated body, before transforming back into "Tomura" himself. All For One tells Spinner not to worry as his recovery is progressing smoothly, gradually overcoming the Quirk Singularity. Spinner asks if he's "still Tomura", which he claims he is. All For One and Skeptic proceed to convince Spinner to take on the role as the commander of the Paranormal Liberation Front, to liberate the heteromorphic villains to their cause. Reluctantly taking on the role, All For One confidently states to him that "everyone can be somebody's hero".

Final War Arc
In the preparation for the upcoming battles, All For One offered up additional Quirks to the other members of the League; Dabi declined but Spinner accepted. Having determined that Kurogiri was being held at Central Hospital, and him not only being the High-End Nomu closest to perfection, and with his Warp Gate Quirk being instrumental in their success, he tasks Spinner with freeing him. He gives him two Quirks, Body Bulk and Scalemail, both of which will give him the strength, defence, and appearance of a true leader, commanding an army of heteromorphs consisting of Paranormal Liberation Front members and civilians to storm the hospital. He also gives him a recording device containing his and Tomura's voices to wake him up, and in case that fails, implants a micro device in Nana Shimura's stuffed hand which will reactivate him once given.

For the next several days, All For One continues to watch over Class 1-A using the Search Quirk, seeing their fruitless efforts in attempting to track him down. Believing that the time is right, he prepares the next part of his plan and contacts the Aoyamas. He thinks about how lies don't work on him thanks to a Quirk that he stole back during the first era of Quirks, which has grown stronger due to his mix of his other Quirks. He recalls the original owner being a disappointment, however his descendant has become much more impressive, even working alongside All Might to bring him down. Either way, he figures the Quirk will bring him victory.

He calls up the Aoyama Family, asking for a "40 year Macallan" which they respond will be "aged 16 years" that their "son will deliver". He asks for their son's contact info, which they agree too. All For One senses no ill will, lies, or deception in them, meaning they're telling the truth through their coded conversation, and all prepared, is ready to meet up tomorrow. He then calls up Yuga, who also through no deception in his voice, informs All For One of the meeting place and where he will lure Izuku to.

In an abandoned parking lot outside U.A., All For One finally re-emerges in front of Izuku after Yuga deliberately lured him out in the opening successfully. He thanks Yuga for delivering Izuku as promised, asking how terrifying it was for betraying his friend, and congratulating him on his big speech about his goals, having also promised his family a blessed existence in his new world.

Unfortunately for him, Yuga overcomes his fear against him and turns against All For One, attacking him with his Navel Laser. All For One is caught off guard by the attack while Yuga hides in Izuku's Smokescreen, with the two noting how he completely fell for their trap, and Yuga declaring for his mom, dad, and everyone's sake that he'll fight him. All For One is disappointed and confused, having not sensed any lies or ill-intent in their conversations, unsure of how they deceived him.

Annoyed, All For One states that even if it was a setup, he doesn't care because his prize is within reach. One For All is so close to him, and using Search, he knows all the Heroes Tomura fought in the War are miles away, so uses his Warping Quirk to summon the Paranormal Liberation Front to overwhelm One For All and finally seize his prize.

However, All For One is once again taken aback when he spots Kurogiri's Warp Gate starting to appear behind them, wondering how they activated him. He thinks this saves him the trouble of getting him back, only to spot Neito Monoma appearing from one of them. As the Heroes begin emerging from the gates, Yuga declares to All For One the one thing he knows he fears most is that Japan isn't finished and if they can lead the way, it will inspire the rest of them, so today is the day where he falls.

The second War has began, and the heroes and villains rush to attack each other. All For One wonders if they plan on fighting in an all-out brawl, when All Might activates the Troy defense system, as cages emerge from beneath the battlefield, capturing all the villains in individual metal containers. All For One knows they're aware they could break through them all easily, until he realizes what their plan is. Just as they're all able to bust out after a few seconds, that gave the Heroes just enough time for Neito to summon several more Warp Gates around the cages, allowing the Heroes to shove them all in, separating the villains.

All For One and some of the villain army are teleported to the ruins of the Gunga Mountain Villa, where Endeavor and a squad of Heroes corner him. Hawks attempts to strike All For One straight in the head with his Quirk, but failing to get through his mask. The heroes recognized All For One's Warping Quirk from the Kamino Incident to be inferior to Kurogiri's Warp Gate, taking it all into account when they built the U.A. Barrier, and that his hubris will now lead to his downfall.

All For One mocks the heroes' plan to split them up, pointing out that dividing their forces due to the decline in heroes was necessary, while also noting the supposed ill-fated decision to pit "One For All" against Tomura, and worst of all to have Shoto face off against Dabi, with All For One criticizing Endeavor for having his youngest son clean up his mess, and continuing his abuse toward the oldest.

As the fighting continues, Endeavor and the Heroes receive word that Dabi has been defeated by Shoto, causing him to react. In response, All For One comments on Endeavor's face, taunting him that he allowed his youngest son to take the burden of defeating his eldest sibling. Hawks tells Endeavor not to listen, expecting his upcoming verbal assault, while All For One continues, berating him for not even looking at Toya and letting Shoto handle everything, confidently stating that is why he'll never win, as he prepares to attack with his arsenal of Quirks.

All For One attacks Endeavor with crescent shaped projectiles, which he manages to block with Hell's Curtain. Hawks shoots some of his feathers through the fire, aimed at All For One's helmet. All For One deduces their strategy and realizes that the two heroes are coordinating their attacks together to destroy his life support mask as he blocks the feather attack. Hawks attempts to attack from behind but All For One once again blocks the attack and taunts the number two hero, stating that even Recovery Girl couldn't save all his feathers and that he needs to use prosthetics in order to be at his top speed but Hawks just laughs him off.

Hawks flies away just as Endeavor comes in and attacks with Vanishing Fist. All For One notes that he can't block the attack with Impact Recoil and that Endeavor's heat is passing right through his Hardflame Fan shield. However, he also notices that Endeavor's attacks aren't quite on the same timing as Hawks' attacks. He uses this opportunity to further taunt Endeavor for not being completely focused on their battle and asks him if he's thinking about Shoto and Dabi.

He then reveals that he's had his eye on Endeavor for decades, as Endeavor tried his hardest to surpass All Might. He then finishes his taunts by asking Endeavor about not finding Toya's body, revealing his role in his disappearance. This enrages Endeavor who screams at All For One and attacks, only for the villain to take a massive slice at Endeavor's side with a massive Quirk protrusion on his arm.

Endeavor falls to the ground below as Hawks charges at All For One. He prepares to obliterate "Nagant's Replacement" with a massive Air Cannon blast only for Hawks to be saved by Heartbeat Wall, courtesy of the arriving Earphone Jack flying on top of Tsukuyomi. All For One disgustingly refers to the two students as gnats, referring to how in the comic that he read as a kid, there were always side characters that only existed to be killed by the Demon King as a show of power. Earphone Jack confidently brushes him off, telling him to save the insults until he's actually defeated them.

As the two student heroes in training join the battle against All For One, he notes that he needs to get back to his "other self" and realizes that the heroes are going to try and buy time for Endeavor to get back up and rejoin the fight. He turns his attention to Earphone Jack, deducing her as the weakest link in their group, and attacks her by shooting several heads at her. Hawks manages to use his feathers to save her and then lands another strike on All For One's helmet with his sword. All For One notices and taunts Earphone Jack for showing fear, chastising her for seeing this fight as "just another lesson from school", calling her just a mere extra.

He prepares a massive blast attack with his left arm and simultaneously holds back Hawks with Rivets from his right arm. His attack lands on Earphone Jack, blasting one of her Earphone Jacks off. Despite the pain, she relents, decrying All For One's beliefs, and fights back with her Heartbeat Surround: Legato Ultimate Move. The attack barely phases All For One who further taunts her for such an underwhelming attack.

Suddenly, he is held back within the vestige world of his Quirk, as the vestiges of the Quirks he has stolen over the years begin fighting back, restraining All For One and making him unable to use any Quirks. All For One comments on how even New Order wasn't able to achieve this, wondering how they were spurred on by such "weaklings". This leaves him open for an attack as Hawks, aided by Earphone Jack's soundwave attack, lands another blow on All For One, shattering a piece of his life support mask.

As All For One is still stunned, Tsukuyomi uses Dark Shadow to land another massive strike on All For One's shattered mask, successfully destroying it. As All For One ends up stunned by the attack, he notes that his awareness and reaction time is off due to the vestiges within his Quirk rebelling against him. He realizes that since he gave up his orignal Quirk to Tomura and is using a synthetic copy, his authority over his Quirk has lessened.

Within his vestige world, he begins to eat the other vestiges trying to rebel against him in order to reclaim control over them. Outside, Hawks prepares to land a killing blow only for All For One to angrily unleash a massive burst of Rivet Stabs in all directions. Hawks is caught in the attack and severely injured while All For One uses the opportunity to reassemble all the broken pieces of his life support mask in an attempt to put it all together. Suddenly, Endeavor re-enters the fight, fighting through all the rivets. Even as he loses an arm, with All For One taunting him for his doggedness, Endeavor persists and creates a massive flame fist where his arm used to be and smashes All For One, once again shattering his mask.

All For One manages to barely protect himself from Endeavor's surrounding fire. He thinks about how he knew he might go hard on him, but never expected Endeavor would be the one to make him relive the pain he had when he originally faced All Might, reminding himself that a wounded hero is always the scariest. He's then caught off guard as Endeavor closes the distance, unleashing a Vanishing Jet Burn attack, blasting him downwards onto the Gunga Mountain battlefield.

Before he has time to fight back, Endeavor blasts himself downward, grabbing him and dragging him all throughout the forest. Due to his mask being destroyed and his body not listening to him, All For One tries to grab Endeavor and steal his Quirk, but he proceeds to shoot fire from his eyes, burning his hand. Endeavor states that all his hands do is ruin people's futures, to which All For One claims he does too, but to which Endeavor simply agrees. Blasting his way into the air, and despite All For One's attempts to stop it, Endeavor unleashes a Prominence Burn, engulfing All For One completely and reduced him to a crisped corpse.

All For One is seemingly dead for good, but suddenly, he begins to speak, asking Endeavor if he believed he would show up to the big battle empty-handed. With his body having served its purpose and destined to be scrapped anyway, he has decided to test something out. As an eye and an ear begin to emerge from the villain's head, with a grinning smile on his face, All For One asks what made him think Heroes were the only ones to make "sacrificial moments", and that Villains are also scariest when wounded.

Meanwhile, "Tomura", whose mind has almost completely fused between Tomura and All For One, has been fighting off a group of Heroes at the floating U.A. Fortress, overwhelming them with his immense strength and growth courtesy of the Quirk Singularity. However, upon his confrontation with Lemillion, claiming he doesn't have any friends, the deep spirit of Tenko Shimura re-awakens, causing "Tomura" to hysterically rebuke his claim.

This action causes the All For One side of the personality to re-take control, realizing that despite him supposedly being fully assimilated, he can sense that "Tenko" has not fully melded together yet. Knowing they can't let the action continue on any longer, "Tomura" heads over to try and finish off Katsuki, in order to enrage Izuku once he finally arrives.

The Heroes continue to try and throw everything they can at the villain but it proves fruitless to stop him. An incredibly injured Katsuki then steps up once again and utilizes his speed to dodge and evade each one of "Tomura"'s attacks from up close. "Tomura"'s actions begin to get more hectic, wondering how he is getting so pissed off at and panicking by an "extra" who doesn't possess One For All, causing All For One to suddenly have a flash of a memory to the Second User of One For All.

Despite the quick movements, "Tomura" is successfully able to land a hit right in Katsuki's chest, bursting his heart and seemingly killing him for good. While the Heroes panic over Katsuki's lifeless body, "Tomura" laughs that "they've" come prepared with the perfect Demon Lord body for the Final Boss, and that this is their story, the Villains' tale.

Despite his domination, the Heroes continue to put up a fight, with Edgeshot attempting to revive Katsuki from the inside. All of this makes Tomura increasingly more unstable, causing him to undergo another transformation, with his entire body compromised of fingers. This new increased strength is able to overwhelm the remaining active Heroes, but Lemillion is able to distract "Tomura" for long enough for the electromagnetic barrier to be opened, allowing Izuku to join the battle, slingshotting into "Tomura" with a smash.

Upon being sent backwards, "Tomura" notices that Izuku is stronger now, with All For One recognizing the glow around him as being the Quirk of the Third User. Izuku then realizes the fate of all the other Heroes, with "Tomura" ready to take advantage of his imminent emotional duress to counter him. However, Lemillion steps in to calm Izuku down, and back under his own control, Izuku confronts "All For One", asking if Tomura is still in there.

"Tomura" simply responds that he no longer exists; Tomura and All For One have fully merged into a new being, and supposedly due to him being older, All For One is currently in charge, saying that despite whatever he's scheming, he won't get his ideal ending. But then, Lemillion tells Izuku about what happened earlier when he spoke harshly to him, which caused him to throw a fit as if he were a child, figuring he isn't "fully merged"; the more he was provoked, the more unstable he became, which starts to irritate "Tomura". Seeing the disembodied faces of the Shimura Family on his left arm, Izuku and Nana Shimura realize that Tomura is still in there, causing "Tomura" to retaliate.

Jumping into the air with all his power, shaking the entire Fortress, "Tomura" charges at Izuku angrily declaring he's taking back One For All. His smash erupts throughout the whole battlefield, but Izuku is able to stop the attack, telling All For One he's the one who won't get his ideal ending. He uses a combination of Blackwhip and Fa Jin to create the Blackchain, wrapping it around "Tomura's" arm and sending him flying. "Tomura" attempts to try and restle the chain off, not intending to fall for the same move again, only to be surprised when Izuku undoes it himself.

He then notices Izuku concentrating to himself, when suddenly, in the blink of an eye, he appears under "Tomura", punching him with at such a tremendous speed and sending him flying upward. "Tomura" is completely caught off guard by the attack, realizing its strength and speed is different from the glow he was using before, and that he is currently using a different Quirk, the one of the Second User, Gearshift. Thanks to its ability to let the user shift and change the target's speed when touched, Izuku enables Gearshift: Overdrive, turning his 100% power into 120%. Yoichi declares to his brother that today is the day they finally end things, as Izuku unleashes a fully powered Detroit Smash directly into "Tomura's" stomach.

Seeing the power of Gearshift causes All For One to recall back to his encounter with the Second User of One For All, when his Meta Ability was only able to work on small objects, being nothing more than a "peashooter". He states that all he was meant to be was an insect in his path, becoming further enraged at how much the power has grown, just as he and Tomura are able to see the vestiges of One For All around Izuku. After crashing into the battlefield, Izuku comes at them with a Detroit Smash: Quintuple, knocking them further down. "Tomura" notes that the attack wasn't as strong, due to him not having his "built up glow", and despite being too fast to see, he figures he can predict his next attack based on the previous timing. However, he misses the swing, as Izuku shifts into Low Gear at the last moment.

"Tomura" attempts to counter again, but Izuku uses Danger Sense to detect the threat, and immediately block his vision with Smokescreen. He then uses Float to quickly rise into the air, restraining and reeling "Tomura" up with Blackwhip, preparing to combine the power stored up thanks to the Quintuple attack with Fa Jin, executing another blast of Overdrive with Gearshift, unleashing the full might of One For All.

The Second User states that their Meta Abilities were never what All For One should've been worried about, rather he should fear the reason why someone chooses to use their gifts; true power lies in an individual's intent, which is why people call them "Quirks". Izuku declares that he's giving it all he got, telling All For One he won't let him hurt anyone else, and despite "Tomura's" screams in defiance, Izuku pounds him with his ultimate smash, breaking many of his fingers apart.

As "Tomura's" body falls with a gaping hole in his chest, Yoichi states how One For All and All For One have begun to resonate with each other, able to see his brother within as the vestiges of Tenko, Tomura, and All For One attempt to recover from all the damage. He continues that what Lemillion said is correct, that the course of the battle, and the events that led to this moment, has shaken the balance of their melding.

Meanwhile, "Tomura" laments over Izuku not holding anything back and using all his Quirks, while he hasn't been able to use a single Quirk yet, unable to show the true power of his body all because of Eraser Head's Erasure, the U.A. Coffin, and all their underhanded tricks. Just then, his body starts to undergo another transformation as the massive hole in his chest begins to swell and expand.

Back at the mountains, All For One is revealed to have used his trump card that is the reverse engineered Quirk-Destroying Drug, rewinding his body back to his prime state. He tells Endeavor and Hawks that while the Heroes managed to keep the Villains on the defensive during the previous war, it won't be the same now: since Heroes are those who defend, Villains are those who violate, and they will plunge headlong to their dream.

He further compliments Endeavor, not thinking he'd have to play the card against him, and with how light his body feels, he swiftly makes his way down to the battlefield, stealing the Quirks off nearby Heroes, as well as their capes to cover his nudity. Hawks quickly pushes a Hero away, while All For One reveals that after using the drug's Rewind effect, he's doomed to vanish, but since his dream has already been passed onto Tomura, he intends to rescue him from the Heroes' trap before he's gone. Hawks, attempting to stall for time, asks All For One what is his dream after obtaining One For All.

All For One explains that he was influenced by comic books, and asks Hawks why Villains are feared over the world. Hawks responds it's because they do bad things, but All For One states that in a world full of different cultures and values, those "bad things" would be an action that the masses react to in disgust; it is something that thwarts the future they envision. It is because of this that All For One wants to thwart the future of the world, as it's all he's ever wished for. He declares that if everything that has happened will spell out victory or defeat for all, then victory still lies within his grasp.

To add further cause to his ideals, All For One declares that people's experiences when they're young define who they become, referring to Spinner's dark upbringing, so his feelings for the friends who accepted him are strong. He reveals his plan to have Spinner free Kurogiri, also mentioning he installed a microchip in Nana Shimura's hand to make sure he was active no matter what state he was in.

As two Warp Gates appear above the battlefield, he yells that Spinner has succeeded. Dabi gleefully emerges from one of them, saying hi to his dad, while from the other emerges Himiko, now transformed into Twice, calling out to Hawks. All For One states that the "sad man's" death gave rise to the hatred in Himiko's heart, further aided by Dabi, in his quest for revenge, giving her the tool she needed to destroy all. He tells Hawks to watch and see what will happen if he hadn't made his death his top priority before, causing Hawks to panic. Right before Hawks could attack Himiko, she unleashed Sad Man's Parade all over the battlefield, swarming the heroes with thousands of Doubles.

With the heroes now in full retreat, All For One laughs as this is going on, thinking about how the chain of events is working in his favor, and figuring that Kurogiri warped himself to Tomura's location. He also thinks about how he should think about obtaining the Warp Gate Quirk for himself, as it is far superior to his sludge Warping Quirk. He attempts to use the chaos as cover and blast over to Tomura himself, but Hawks blocks him, asking him why he is in such a rush to leave, even despite the Rewind effect, realizing he doesn't have faith in Tomura's "perfect body".

Annoyed by Hawks' cleverness, All For One responds that he's right the body isn't complete, and that he is still essential for the process. Hawks cries out to Endeavor that since their divide and conquer plan was a bust, if things fall apart now it will eventually reach Deku and Tomura, so they need to stop Dabi now. All For One attempts to lambast Hawks by reminding him that Endeavor's already lost an arm and that he's supposed to be trying to stop him rather than abandoning his duty, but Hawks smugly responds that he's already lost to him once.

Back at U.A., thanks to Kurogiri and the Twice Doubles, Shota and Neito are attacked, undoing Erasure, causing "Tomura" to unleash a massive explosion, destroying most of the U.A. Fortress. However, as a result of the massive damage done to the body, the All For One vestige loses control of it, still attempting to recover, while Tomura re-emerges from his skin within.

As All For One struggles to retake control, Tomura attempts to attack, but both his arms are shot off by Lady Nagant, sniping from atop the hospital below. All For One, within Tomura, hysterically cries out to her, lambasting her for trying to play the victim after murdering her fellow Heroes, only to be shut up by Tomura who unleashes a hoard of fingers out of his mouth. All For One realizes too late that his control over Tomura has started to wane as Tomura laughs asking if his attempts at manipulation have failed and mocking his current state. He further criticizes his attempts at grooming him, using All Might and Nana Shimura to irritate him, scheming to hijack his body and soul and attempt to absorb his hatred to steal One For All.

However, as they merged together and became part of him, Tomura admits that he hated all of it, so he hid his own core deep within his own soul, and without him noticing, he has been reclaiming himself from the inside and out, both body and spirit and desires to follow the path toward his origin. Infuriated, All For One tries to command Kurogiri to transport him to his other self at the Gunga Mountains, but "Kurogiri" begins to stutter, unable to comply.

Tomura decided that he doesn't need One For All, and that he won't let himself be controlled anymore. Breaking free of All For One's vestige, he states that his heart won't waver, and that everything that exists in the world led to the existence of the house he grew up in. Now back in complete control, Izuku knocks Tomura outside U.A. where they prepare to fight once again.

With Tomura now free from his influence, All For One continues to try and escape Hawks' pursuit at Gunga. He explains how he was supposed to have full control of Tomura's body, and that the fusion and new personality weren't part of the original plan. He stated how he underestimated Tomura's desire for destruction which was stronger than he anticipated, but nonetheless, all he has to do is get him to absorb his Quirk Factor, and he will be regain control of Tomura once again, allowing the creation of the "Demon Lord" to be complete. Hawks retorts back that it isn't his story, but theirs, and not his to do as he pleases, as he continues to swipe at him and prevent him from escaping.

All For One mocks that the winds are blowing his way and seemingly kills Hawks by destroying his body with a spatial distortion Quirk. But then suddenly, Hawks' face turns all "glittery" and simply fades away, revealing him to be an illusion created by Camie Utsushimi who had just arrived on time with reinforcements from the Hero students of Shiketsu High School. Inasa Yoarashi proceeds to unleashes a massive Whirlwind which sucks up all the Twice Doubles, as he declares he is the one who decides which way the wind blows.

With the Shiketsu High School students joining as backup, the Heroes throw their full assault into attacking All For One to prevent him from escaping. He touches one of the Twice Doubles, only for it to melt, thinking to himself how he can only steal a Quirk by touching the user's body directly, and while they only attacked him with two people at first to avoid that risk, now they've become desperate they're willing to accept the risk, which he smiles wickedly at.

Despite the arrival of reinforcements, All For One still manages to overpower every one of them. Using several thorns extending from his back, he unleashes a massive laser explosion, decimating the battlefield below. The Heroes, however, stands their ground, to keep their defense strong and continue attacking, especially now that he's stopped running away. All For One monologues asking what makes them think they will emerge this time, that they lost the only one who could face him head on, and how ignorant he believes they are; with none of them being born from his golden dark age where his powers are at his peak, with some of them only having witnessed All Might's rise to power, and most being born when he reigned supreme.

All For One tells them he has lived in an era when people trembled in fear of something lurking in the darkness, when all were tainted by suspicion, resentment, exploitation, and prejudice; and how it was his golden dark age. Inasa proceeds to attack him with his Whirlwind and berates him, retorting they knew about that period through history class, and that he's decided to root for Endeavor and Shoto, believing hot-blooded passion will always triumph over fear.

In response, All For One decides to try to steal some Quirks, unleashing another hell of Rivet Stabs that manage to slice part of Inasa's face. Yet despite being injured, Inasa continues fighting and states his Quirk is even stronger on windy days, and that instead of All For One's ancient glory days, he'd rather see a future built by the people he's cheering on. With the Heroes throwing their attacks into the Whirlwind cage, All For One becomes irritated at the look in their eyes, looking past him and are constantly stoking the flames even after the light has gone out. He rebuked that it's all for naught since they won't come too close for fear he'll steal their Quirks, however, he then suddenly feels an ominous presence behind him, and is stunned into silence as a massive "dark shadow" emerges from behind. All For One then realizes what it was that made him tense up when he faced against this being earlier.

Now completely immersed in total darkness, thanks to the dark clouds blocking the sunlight, the flames dying out by the rain storm, and covering himself in the Earth to pile up the darkness, Fumikage tells All For One that even darkness comes in a range of shadows, and that they've already devoured the filthy darkness that he brought, as he reveals Dark Shadow's giant monstrous form at his Total Release of full power. Fumikage tells him what All Might said, how he can't steal Endeavor's Quirk just by touching his flames, which is why he was tasked with supporting them, since he can't steal the Quirk just by touching Dark Shadow. Fumikage proceeds to use Dark Shadow boosted by Inasa's Whirlwind to unleash Black Abyss: Light of Baldur, pulverizing All For One down into the ground.

Fumikage continues his assault on All For One, but eventually, he is able to retaliate by unleashing a massive nuclear explosion that blasts away Dark Shadow, greatly diminishing him once again. All For One states how obnoxious they all are, and as a result of the Rewind effect, he has become visibly younger and more powerful than ever. Now free, All For One uses his Quirks to blast his way out of the battlefield.

The Heroes give chase, with Inasa carrying them with his wind, refusing to let him escape, when to everyone's surprise, Gigantomachia suddenly appears on the battlefield. All For One smiles, commanding him to finish them, but instead, the beast throws a giant mountain boulder directly at his master, much to his surprise. All For One is infuriated, cursing out the insects who were on Gigantomachia's back, Eijiro Kirishima and Hitoshi Shinso, who is currently Brainwashing Machia.

Realizing that Hitoshi was the one who was controlling the behemoth, All For One deduces Hitoshi's Quirk was how they were able to get the Aoyamas to deceive him, commenting that it is his tactic. Now aware of what Hitoshi's Quirk can do, All For One fires off a huge wave attacking Machia with a giant blast in attempt to kill him.

Although Eijiro was successfully able to defend Hitoshi with Red Riot Unbreakable, All For One succeeded in the attack that seemingly break control away from Machia. However, Machia responds that even though he looks different, he can recognize his scent as his master, proceeding to ask why he left behind. When All For One doesn't respond, Machia tearfully then yells that even after he came back in Tomura Shigaraki's body, despite having faith and waiting for him, he still abandoned him and ran away. Full of anger and rage, Machia turned against All For One for neglecting and abandoning him all these years and viciously attacks him. With Machia now officially the Heroes side, the Heroes plus Machia throw their full assault on All For One until he vanishes for good.
