Template:Toshinori Synopsis/Final Act

Dark Hero Arc
After defeating and sending Muscular to prison, Izuku meets All Might in an alleyway, who was waiting for him by his car, Hercules. All Might asks him if he is hurt, and Izuku reassures him saying that he is fine and that the Mid-Gauntlets were very useful. All Might reminds him that the item is still a prototype and they were made for endurance; they will reinforce his body but they can't handle 100% output, therefore he can't go overboard until his rematch.

All Might's phone rings, picking it up to hear Hawks speaking to him while he, Endeavor, and Best Jeanist contain a villain. Hawks asks how Izuku is doing and All Might reports he is fine, but he immediately departs, having received another warning from Danger Sense. Hawks surmises he is worried about putting anyone else's lives in danger, adding that while they could potentially keep him completely isolated to prepare for what is to come, knowing the capacity of power the ones who attacked Tartarus possess, it will be all over if they come well prepared.

Because of this, following Izuku's idea of actively seeking out their enemy will raise the odds of their victory. Hawks knows how tough a position this is for All Might, and that even though he's worried, the best they can do right now is support him.

During a stormy night, after Izuku saved the life of a woman who was being attacked by people mistaking her for a villain, All Might arrives on the scene to help. Izuku asks him to take her to the shelter, but not before he hands him a lunch box to eat which he thanks him for.

Later, while following Izuku from a safe distance, All Might thinks that Izuku is trying too hard at his task without hardly resting, and this reminds him of the conversation he had with his sidekick Sir Nighteye when he was convalescing from his injuries from his combat against All For One, when he wanted him to retire from hero work and take a break now and then. This memory is interrupted when he realizes Izuku's GPS signal has disappeared. Then, a grenade is thrown at his car and explodes. Fortunately, Hercules manages to withstand the explosion and All Might is unscathed.

Two villains appear ready to throw flaming spears at him, and All Might instantly realizes that this is not an ordinary attack but with clear intentions to kill him. All Might grabs a spare phone and alerts the rest of his team that the villains are trying to separate them from Izuku, who must be facing off against a villain. All Might manages to get out of the car with a suitcase before the villains destroy it with their weapons.

The villains are surprised to see All Might, but don't stand down since he isn't the same as he was before, saying the real All Might died a long time ago. However, when he demands they stand aside, the villains start shivering in fear when they feel his immense aura of intimidation. All Might remembers the promise he made to Inko as he tells the villains that Deku is bearing more of a burden than he himself ever did yet he still idolizes him, and he yells that the day anything happens to him is the day he dies.

While he is busy dealing with this two villains, Izuku confronted Lady Nagant, a villain sent specifically by All For One to capture him, but managed to defeat her. As a preventive measure, All For One implanted in her a Quirk of immolation that made her explode. Thanks to the previous call from All Might, Endeavor and Hawks manage to reach Izuku and take care of the charred Lady Nagant, who is still alive. Minutes later, All Might finally arrives asking Izuku if he is okay and Endeavor ensures him that everything is under control.

Sometime later, Izuku defeats another assassin sent by All For One and immediately tells All Might that he knew nothing and to be careful in case he is rigged to explode. All Might yells to Izuku to stop so he can give him some more food, but Izuku tells All Might that he doesn't need to follow him anymore, saying that he is fine on his own now. All Might tries to speak but Izuku claims he can practically move at 100% without injury just like he could, so he shouldn't worry about him. He wants to tell him to rest, but he can't as Izuku leaves, and All Might trips as he tries to reach out to him.

Eventually, Izuku is cornered by Class 1-A and taken by to U.A. for some well-needed rest. However, instead of checking up on him, still depressed about him leaving him behind, All Might returns to Kamino, in the aftermath of his battle with Class 1-A, intending to check in on the anti-hero supporters who refused to evacuate, while still thinking about being unable to help Izuku. Looking at the statue of his former self, he berates himself for doing nothing and just dragging everyone down. Stain then suddenly appears above him, holding his sword near his neck and demanding he take back his slam against All Might.

All Might realized it is the Hero Killer and notes how Stain never went after him when he was active and they didn't get to have their meeting till now, but the Hero Killer becomes confused, leading All Might to clarify who he is by quickly transforms into his muscle form to prove it, but Stain reacts in disgust, refusing to believe that was him just now, calling him a sham and why he presumes to call himself a "hero."

All Might responds back to Stain's claims in agreement, explaining how he couldn't handle the uneasiness of the world, and despite being powerless, he wanted to make the world a better place, but now he's reached his end point. With so much chaos in the world, and unable to protect the student he promised he would, he feels like he's gotten further away from heroism than anyone.

Stain leaps forward and pulls All Might back behind an ice block, before pointing him toward the statue. The two see a girl pulling down the "I Am Not Here" sign off of it, which Stain says she has been coming by to clean the statue from the vandalism every day. All Might is confused why she would put herself in danger just for that, until Stain reveals she is the last person All Might saved: the girl from the Kamino Incident.

Stain exclaims that what All Might did as a hero had nothing to do with his Quirk, but that he always kept a smile on his face and did everything he could to help people. That the embers of inspiration he left behind continue to burn within those who followed him, and have now started to form a great fire, so they all must continue to stoke the flame so that it won't die.

After Stain reveals he knew about what happened regarding his true state, he tells him that if he is a true hero, to make use of his information from Tartarus, throwing him a knife and several pieces of paper, as well as telling him to end "the man who murdered 40 heroes" to fix this society, before walking away.

Shortly after this, All Might returns back to Heights Alliance, where Class 1-A has just finished bathing down Izuku. He busts into the dorm and apologizes himself to Izuku for not helping him enough despite his protests, but Izuku apologizes back for abandoning him too. The other kids demand an apology for leaving them abruptly as All Might says that the decisive battle is drawing near. He tells everyone that he has acquired some new information that will help them, thinking back to Stain's words, and that he has decided to continue supporting everyone even though he is Quirkless. Izuku speaks up and tells All Might that the food he made for him gave him strength, and chalked his hardships to not having him at all.

All Might heads back out to meet up with Naomasa, after giving them the data Stain had given him. Naomasa reveals that since Tartarus' systems are cut off from the outside world, they would've had no way of getting this data normally, and that it contains the cause of the system shutdown, which was "Tomura" and All For One's constant blasts of Radio Waves inside and out.

Sansa suggests that this is because All For One was synchronized with the vestige within Tomura, however All Might reveals that the communication isn't a two-way channel. Just like with his vestige within One For All, while the vestige has access to all his current thoughts, All Might himself has no connection to the vestige itself, at least until he was able to make contact with Izuku back at the Hospital. Because of this, All Might believes that even All For One wouldn't be able to have such direct control over the vestige from so far away.

Naomasa then says that the two All For One's were able to communicate through the Radio Waves Quirks, and that the recorded waveforms on the data disk resemble a conversation that says: "Make him complete in 38 days." The revelation shocks Sansa, as Central Hospital's research stated it was 2 months till he was completed, but All Might says it's possible he rigged the results as a bluff, and that if they are to take their conversation as the truth, Tomura will be complete in 3 days.

Star and Stripe Arc
With Tomura's near impending completion, All Might calls in to the foreign heroes for assistance. While the rest are unsure, America's No. 1 Hero Star and Stripe, who considers All Might her spiritual master, makes her way over to help. During her impending arrival, she is ambushed by "Tomura", and in the aftermath of her battle, Star is killed. However, when "Tomura" stole her Quirk, she had turned it into a virus at the last minute, causing various of his Quirks to be destroyed and forcing him to flee.

Although All Might was currently at U.A. during all this, it wasn't until Star's American jet fighter pilots returned to tell him of her death. He lamented with sadness about wanting to see her again, however, the pilots tell him their fighter jets have a record of the battle, and were able to measure all of Tomura's bio-signatures, as well as every Quirk during the fight, providing the data to them to use, alongside the ones already being studied at Central Hospital.

U.A. Traitor Arc
The next day, two days after Izuku had returned to U.A., All Might informs Class 1-A that Tomura was supposed to have his body completed by the following day, but thanks to Star's New Order, it acted like a poison when Tomura stole it, eating away inside him and destroying a large number of his Quirks, with the class realizing now's their best chance to take him out. He continues that the remaining Heroes have been continuing the mass evacuation effort and hunting the remaining Villains, and reminding them that due to how unpredictable All For One is, all out war is inevitable.

He reminds them of their current targets: Tomura, All For One in his original body, Dabi, Himiko Toga, the remaining six Near High-End Nomu, the remnants of the Paranormal Liberation Front, and the remaining escaped convicts, also including that they'll be likely to amass more allies too. All Might continues that while less than half of their heroes remain, it is thanks to Star's sacrifice that they have a chance to use this time for everyone to grow even a little bit stronger.

In response, Katsuki yells at All Might that they've already been doing this. Class 1-A reveal that since the War, they've continued their training with the Wild, Wild Pussycats, all with the intention to fight alongside Izuku until Tomura is defeated. The rest of the class each respond with enthusiasm as they all prepare to go out and train. All Might watches on, thinking about how the "zygotes" from the first day of class have hatched brilliantly into fledgling heroes. He thinks about how All For One has made a foolish mistake underestimating them, and that Class 1-A is a mighty force to behold.

Unfortunately, his spirits were shattered when he and the other U.A. staff are informed of U.A.'s traitor being captured by Izuku and Toru, revealing to be Yuga Aoyama. In the U.A. A.V. Room, the Aoyama Family are interrogated by All Might, Detective Naomasa, and the U.A. staff, learning Yuga was Quirkless and received his Quirk about 10 years ago from All For One, so his family was forced into his debt.

After interrogating them on information regarding All For One, Izuku speaks up as he recognized Yuga's troublesome situation and had no malicious intentions in his actions, so wants him to help them and prove he can still be a hero. The rest of the class believes this as meaning they can use Yuga to deceive All For One, but Naomasa reminds them that it is still very unlikely that could work. Just then, Shota Aizawa, listening in on a tablet, informs everyone that he has an idea, which they all listen to after covering the Aoyama Family's ears. Nezu says that it seems possible, and All Might adds that it'll be up to how well "he" can handle it, as Naomasa escorts the Aoyama Family back to their HQ, telling everyone not to say a word to anyone else about the plan.

With the plan preparing to go into motion, and Class 1-A heading out into the streets to hunt down the villains, All Might and Hawks form the "Counter-Force", including Ragdoll, the Police Force, and Star and Stripes' American military task force. At the start of their meeting, he informs everyone that after deeming them all trustworthy, and with the other big Heroes currently out in the field, they'll be keeping their current circle small to detail the classified information.

All Might demonstrates their scenario by placing tiny refrigerator buttons of the villains on a whiteboard, stating that whether they're going for Plan A or B, what they must do no matter what is to split them up. He further elaborates that the only way they can hope to achieve total victory is by isolating all of the villains that are deemed a major threat: separating each of the League's major operatives, luring them out individually, and defeating them one by one.

Several men say it's easier said than done, with All Might responding they need to have a strategy to make it happen, which Naomasa figures is Yuga. He adds that while he does sympathize with his situation, considering he still turned his back on society, from his position he still has to proceed with caution. All Might chooses to believe in Yuga, and he already believes in his teacher, Shota.

Final War Arc
After the conclusion of the meeting, All Might, Naomasa, and Nezu visit Class 1-A to explain the plans to deceive All For One. They remind them how unlikely it is they'll be able to track them down in their search, however, this works to their benefit as it allows them to draw him out by getting him to loosen up. Naomasa explains how they assume that All For One is using Search to monitor everyone, and everything they've done since Izuku returned will make him believe that they're being exhausted, which will allow them to catch him off guard, and utilize Shota's plan of having Yuga choose the location to lure him out.

Theorizing that All For One has a way of determining whether people are lying or not, in order for the plan to take effect, All Might has recruited Hitoshi Shinso, to the class' excitement. Hitoshi explains that he had to train hard to keep up with everyone, so managed to push through the limits of his Quirk to allow him to get his brainwashed targets to talk, so their plan is to make Yuga and his parents talk so that their motives and emotions won't come into play at all.

During these preparations, Mezo and Koji approach Shota and All Might, asking to be involved in the defence of Central Hospital, surprising them that they know about the plan. Mezo reveals he had spoken to the giant woman, as well as several of the other heteromorph refugees, and learned that there was a "call to action" plan being initiated by Spinner and the Paranormal Liberation Front, calling on the mutants to storm the Hospital in retribution for all the prejudice they've faced. Mezo states he needs to be involved as he can't let this slide, or else he won't be able to consider himself a hero. Shota accepts and allows them to join the team led by Present Mic.

As the day approaches, All Might watches as Hitoshi brainwashes the Aoyama Family when they are in contact with All For One, giving him Yuga's number, followed by a brainwashed Yuga giving All For One their meet-up location, a parking lot on the outskirts of the U.A. "Troy" dormitory.

The Final War begins, and All Might and the Counter-Force observe from Central Hospital, waiting patiently for Izuku to make contact with Yuga who was recently released from his "lawyers", anticipating All For One to finally reveal himself after months of hiding without a single trace. With One For All in his reach, All For One summons an army of villains, intending to end it all here so he can get One For All, using Search to confirm none of the Heroes are anywhere near.

However, it turns out the other part of their plan to catch him off guard was to utilize Neito Monoma to Copy Kurogiri's Warp Gate, allowing them to teleport the heroes immediately onto the battlefield. Now that all the villains have been summoned in one place, All Might activates the Troy system, trapping all the villains in cages emerging from beneath the battlefield. All Might and Naomasa declare that even though they tried to bring him down once before and All Might's stomach was destroyed, they're still alive, and this time for sure they'll take him down. Neito summons several more Warp Gates around the cages, as the Heroes prepare to shove them all in, to split up the villains.

With nearly everyone warped, All Might orders Fat Gum in command to capture the remaining threats in the area and to watch over Yuga. All Might then tells Neito to regroup with Shota as now that the separation is successful, they can begin Phase 2.

As the battles continue, All Might receives word that Shoto has successfully defeated Dabi, getting emotional over his students' success. Naomasa reminds him they need to keep this up, as All Might proceeds to inform the rest of the battlefields of this status, giving them all a boost in motivation.

However, many things of the war eventually turns for the worse on the Heroes. Dabi revives himself after copying Shoto's Phosphor technique, Himiko managed to transform into Twice, All For One regenerates himself by taking a reverse-engineered Quirk-Destroying Drug to Rewind himself to his prime, Spinner succeeds in freeing Kurogiri from his containment, and Skeptic hacks into U.A., causing the floating fortress to start to plummet to the ground. As Naomasa scrambles to contain the chaos, All Might heads out in order to help in his own way. Naomasa protests him to stay out of the battlefield, but he persists anyway.

During this time, All For One manages to defeat all the Heroes attempting to contain him, as a result of getting stronger the younger he gets, and blasts his way over to Tomura's location. Also at this point, Endeavor and Dabi both give chase to each other, with the Counter-Force realizing that Dabi has been internally compressing thermal energy, and that in about ten minutes, his body will explode and cremate everything within 5 kilometers, including the evacuated civilians who are trapped in the middle of the blast zone due to Skeptic's interference.

With all of their precautions failing, All Might makes contact with both the Counter-Force, as well as Shoto and Tenya on the outskirts of the ruined Ido City. All Might informs Shoto and Tenya, who are in Kamino, about Dabi's impending explosion in Gunga, the civilians trapped in-between, and Endeavor being unable to stop it. He says he knows Tenya will be able to run to it, and that after overcoming so many hardships he tells Shoto he knows his mind and body are one. Shoto worries about All For One but he simply says that a "powerful ally" is waiting to deal with him, and that he has the utmost respect to those who still continue to fight even with doubts, telling him to stop Dabi and reassure everyone, to become his best self, and that they need the two of them and their Quirks together to avert the disaster.

Fearful for his friend's safety, Naomasa cries out to All Might through the communicator, but All Might responds that it was always his fight. As All For One quickly approaches through the clouds, All Might asks out loud about their endless warring, further stating that Tomura's hatred has started to affect his main body, which means he won't be able to ignore him. Naomasa cries out reminding him he is Quirkless, which causes All Might to think back to Izuku's words if someone can be a hero even without a Quirk.

All Might thinks back to Nighteye's prophecy of the future about how if he continued down his path of heroism in his conditions, he will encounter a villain that will give him an unspeakably gruesome death, not expecting the "young man" appearing before him to be All For One. He figures if the prediction still holds true, then this is it for him. With nothing to lose, All Might declares his signature motto, "I AM HERE!", unleashing an array of support items and weapons from Hercules and his briefcase. While All For One stares down on him grinning with madness, a mechanical suit begins to form around All Might's body, unveiling his newly advanced weapon, "Armored All Might".

He tells the A.I. computer in Hercules to start recording as he addresses Naomasa to keep him updated on the battle. In spite of potentially facing a brutal death just to buy a few minutes from All For One, All Might smiles on. All For One sees said smile and psychotically asks why he is still smiling and unleashes a destructive laser blast at him. All Might uses Hercules to activate "Red Riot" to shield his body in a protective coating ball, defending himself from the attack. All Might blasts forward into the air as the A.I. states that the shields have been depleted by 66% and he won't survive another hit, but All Might doesn't consider that a problem.

All For One recognizes All Might's classic style of a mad charge without dodging, yelling that it only worked because he held One For All before. Just then, All Might activates several carbon wires, dubbed "Blackwhip" that all snared into All For One, and uses "Chargebolt" to release electrical shockwaves that permeate his body, interfering with his regeneration. All Might yells out that ever since his final battle with his master, Nana Shimura, he's made a habit of starting fights with haphazard long-ranged attacks in order to wear his opponents down before stealing their Quirks, however that approach only works for someone with a Quirk. He uses "Cellophane" to reel the wires into him, and "Sugarman" to build-up his leg kick.

All Might tells All For One he wanted to fight him one last time again, and declares the suit and car are here to keep him in the fight, if only for a bit. He reveals that he came up with the specs and put in the design request, and that it was created by Melissa Shield.

He states how when he was last defeated by him, he sought refuge in the United States where he made a friend, and these weapons are the fruits of that bond that makes him keep on fighting. He yells out that all he's been blessed with will bear its weight against him, telling Naomasa that they've known each other for long enough that he should realize he's never gone into a battle expecting to lose. With his suit powering up, All Might delivers a powerful kick right into All For One's face with a "Shoot Style Smash".

As the hero delivers another kick to All For One's face, All Might laughs about how wrong it feels being over 50 years old and beating up such a "helpless young lad". He thinks about how the villain now harbours a ferocious rage that hungers for One For All, which is what he is exploiting and the only reason the fight is possible. All Might gleefully shouts that any real Demon Lord would be aghast at getting beaten up by a Quirkless man, keeping him in this obsession not to tear his eyes away from him.

Enraged, All For One releases a haphazard combination of Quirks, unleashing a gigantic explosive attack that smashes All Might back through several buildings. He manages to survive the assault using the "Utility Cape Auto-Guard: Dark Shadow" to shield most of the damage, realizing he's randomly combining Quirks, meaning his taunts are working, psyching himself up to keep him riled up.

The A.I. computer in his suit informs him that the cape was destroyed and he's acquired injuries in the clavicle and left humerus, so All Might tells it to set movement assist to max. All For One flies up and re-appears above All Might, calling him a pathetic, washed-up piece of garbage, and how wearing his "trash bag" made him lose all perspective. Since All Might is fighting with his suit, all he needs to do is destroy his gadgets before he can kill All Might because they can't go beyond their own limits. In return, All Might thinks back to advice he gave to Izuku about not relying on support items too much, having seen far too many Heroes who couldn't wield their power after losing their items, jokingly replying that the two of them think alike.

He flies in to punch the villain in the face, however, All For One doesn't flinch from the attack and angrily states he didn't fall for his cheap ploy to stall him since he can easily spare the time to clean up the trash, just before All For One razes All Might with a powerful energy beam. Despite suffering such a powerful attack, All Might simply continues to smile on, and responds by calling him undignified with excuses trying to play it cool.

A device then ejects from Hercules nearby, which All Might uses to stab it directly into All For One, releasing the "Superacid Injection: Pinky". The acid starts to effect All For One, causing his body to rupture, while All Might shouts that he's dissolving away after rewinding some damage, laughing at him for calling him "trash".

The battle between All Might and All For One ends up in Tatooin Station, as All Might is once again flung backwards through several buildings, and crashing on a rooftop. Despite being closer to U.A., All For One is now solemnly focused at chasing and hunting All Might. The A.I. computer in his suit informs him that he has sustained multiple fractured ribs, full body contusion, and his respiratory system malfunctioning.

All Might then spots the same rooftop where he first met Izuku, thinking about the words he said to him, and Stain's words also echo in his mind. Despite taking serious damage and injuries, he does everything he can to stand as All For One once again appears above him. However, All Might notices that All For One has gotten younger, unsure if he himself has noticed, meaning he needs to make sure he doesn't come to his senses. He realizes All For One had to use Quirks to the acid from his body, but the strain is hurting him, figuring taking damage is speeding up the rewinding process.

Just then, as everything that has happened to him within the past year flashes through his head, All Might begins to manically laugh, louder and louder, further inciting All For One's rage, shouting for Hercules to send the remaining parts of the suit to him. The car complies and sends everything it has in its arsenal to All Might, as he activates the Thrusters: Uravity and Ingenium at Full Throttle. With his suit upgraded to the maximum, All Might declares how much of a joy it is to be of service to others, and "together" they will be victorious.

At this same time, the vestige of All Might within One For All senses the battle between his real self and All For One occurring nearby.

All Might and All For One resume their destructive battle, and as All For One continues to try and blast All Might, he uses the newly equipped weapons to evade him: the Tentacole and Froppy suction cups to swing in-between the buildings, alongside the Shoto and Tailman weapons to act as defence.

As All For One chases after him, All Might thinks about how the devices should boost his speed and mobility for tighter turns, aware that All For One must be getting bored of the one-sided struggle, so he needs to set a trap. Assuming that repeated, massive damage to his body shortens his lifespan, he knows just the "Quirk" to get the job done. Because his mechanical armor lacks the efficient power source, he sends the Anima drones to go ahead and solve the issue.

In a backstreet alleyway, All For One catches up to him and corners All Might, mocking him for laughing like a madman one moment and then running away the next, clearly aware of his goal so he has no problem in wasting excess strength, taking it easy being enough to kill him. He grabs the side of the buildings and unleashes an onslaught of River Stabs into the buildings, which he barely evades. All Might blasts himself back up into the sky to get some distance, but All For One counters with two giant Mouth Quirks, halting his ascent. He blasts himself back downward, angrily calling him a liar, but All For One claims he really is just conserving power.

As All Might avoids the attack, All For One mocks All Might about his missing smile, calling him a bag of bones missing half his guts, forced to rely the suit giving him shoddy replications of the students' Quirks. The Rivet Stabs proceed to rip the suit apart one by one, reminding All Might that their fight is being recorded, meaning the whole world is about to watch the Symbol of Peace falling to his doom as the Symbol of Impotence.

While All Might looks back, All For One suddenly ambushes him by breaking through a building in front, saying their guiding light is about to be snuffed out, and lands a devastating hit on All Might right in the stomach. However, All Might knew that All For One was about to do this because he wanted to see his face in excruciating pain so he didn't aim for the head.

Since he need to lure All For One into his trap, All Might uses Tailman to guard himself so he can take the direct hit. However, the attack crushed his spine and his legs still paid the price. Despite the painful injury, All Might retaliates by using Tentacole to ensnare All For One, and shoves Shoto into his mouth, laughing to him that lights flicker on and off, so while his light might be snuffed out, someone will be there to pick up his torch and shine on.

All Might declares to let there be light in the darkness, so that he may twinkle as well. The Anima returns, connecting to a nearby power substation, as he yells at All For One he's not here to lose, and to know this name as he burns away. From above, the Can't Stop Twinkling is activated, sending a giant laser bombardment directly onto him.

Just before the laser rains down, All Might uses the Thrusters to fly away and the armor's "Invisible Girl" optic resin shields him from the laser's immense heat. As All For One is being consumed by the laser, the "Can't Stop Twinkling" device begins to overheat, but All Might insists it keep shooting to keep him pinned down. He declares that he took inspiration from Star and Stripe's final battle, even if he wasn't able to turn the laser into solid matter like she did. All For One attempts to break free from the blast zone, but All Might retaliates with "Sound Wave Vibration: Earphone Jack", intending to keep him within the attack at all costs.

All For One fights back with a web of Rivet Stabs that slice apart more of the suit, so All Might unleashes the "Morphing Armor: Creati" and the "Binding Rounds: Grape Juice" in an attempt to lock him in place. All Might thinks about how he couldn't load himself up with more power than this, desperately hoping All For One finally fades away, while his euphoria is still overriding his pain.

The Can't Stop Twinkling beam finally overheats and explodes. From out of the now exposed crater, a glowing, child-sized All For One emerges, reminding All Might tools cannot surpass their limits. All Might is stunned by his sudden appearance and charges toward him. All For One's back begins to expand, asking if he's forgetting to smile, but suddenly, his body freezes in place, unable to move. All Might looks up to see the Hero Killer: Stain hovering above the battlefield. He managed to swallow some of All For One's blood spilled on debris and use his Quirk, Bloodcurdle, to keep All For One in place. With All For One's movement being halted, Stain shouts for All Might to take him down.

With All For One paralyzed, Stain charges downward on his glider with his katana to cut off his head while All Might flies forward with his fists ready to attack. However, right before Stain and All Might are about to hit him, All For One uses Forced Quirk Activation onto himself and activates his Quirk: Bloodlet, causing his blood to completely expel from his body.

All For One angrily yells out to Stain, having anticipated that he would make a move, since he never joined him and flee on his own after he escaped Tartarus. Stain tries to swallow the spilled blood anyway, however All For One reveals his Antigen Swap Quirk, able to overwrite his own blood type, which is how he's been able to never leave a trace of himself behind.

A fist extends from All For One's back to grab Stain, and crushed his body. All Might rushes toward Stain, only for All For One to thrust the fist, tossing him through several buildings in the distance. All For One appears before Stain's barely conscious body, declaring he'll be taking his Quirk now, and Stain has done his part and now this is where his role ended.

All Might desperately chases after them, calling out to All For One, while Stain weakly coughs out that it didn't end and was all part of the process. He stretches his arms out as a final sign for All Might to live on and triumph, just before All For One smashes right into Stain, killing him. With Stain dead, All For One turns his attention back to All Might and prepares to fire a deadly blast. Just as All Might is about to be hit by a point blank attack from All For One, the last remains of Hercules appears to give him one final shield, repeating that he must live on, as All For One blasts All Might, crashing him through many buildings.

All Might managed to survive the blast, but the attack has taken a toll on him. His Armored All Might suit was destroyed along with Hercules, and he lost his right arm in the process.

Nearly close to death, All Might starts to see a vision of his deceased master, Nana Shimura, encouraging him that he can still do this. Then, a vision of Sir Nighteye then appears, telling him his support items, his legs, and all he's been given are rendered useless, so he can no longer fight. All Might realizes that these are just hallucinations giving him a pep talk to keep fighting. Despite being severely wounded, All Might angrily remains determined, prepared for All For One to do his worst, as he crawls himself back up to fight with everything he's got.
