Template:AFO Synopsis/Final Act

Tartarus Escapees Arc
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 from an unknown location, 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
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. Appearing to use a Quirk-Restoring Drug, 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 Dynamight, 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 Dynamight 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 Dynamight's chest, bursting his heart and seemingly knocking him out for good. While the Heroes panic over Dynamight'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.

Back at the Gunga Mountain Villa Ruins, an almost fully recovered All For One 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.
