Template:Izuku Synopsis/Final Act

Dark Hero Arc
Surveying a nearly abandoned city, Danger Sense alerts Izuku to a nearby threat, which he goes to investigate. He discovers Grand battling an escaped villain, which turns about to be Muscular, and right before he is killed, Izuku saves Grand by blasting Musuclar away with a smash, emerging from a shroud of smoke wearing his hoodie and mask.

Recognizing Izuku from their previous encounter, Muscular joyfully reacts to his reappearance piping himself up for a rematch, while Izuku looks down on him holding the unconscious Grand. Muscular jumps toward the bottom of the building to Izuku's surprise, throwing it into the air, forcing him to jump away. Izuku makes his way to the Taguchi Building where the civilians are held up, and all while shrouded in smoke, quickly hands Grand over to Turtle Neck; he reflects over how many buildings have been destroyed, but declares to make sure no more damage occurs.

Izuku proceeds to converse with the sixth user of One For All, En, asking if he overdid the use of his Quirk, Smokescreen. En provides him some advice to keep control over it, and suggests he try to relax a little, and that rather than seeing the user's Quirks as ultimate moves, to think of them as tools in his arsenal to strategically organize a plan.

Izuku proceeds to use Float to hover above the city, as well as Smokescreen to reduce Muscular's vision, covering the streets below. Remembering the tactics from their fight, he uses Danger Sense to dodge Muscular's incoming attacks, and finally Blackwhip to grab a hold of him and contained on the ground.

Muscular is annoyed at the "cheap party tricks", while Izuku asks him where Tomura and All For One are. Muscular replies he doesn't know as they just told him to go wild after he was freed, and instead proceeds to berate Izuku for just talking and using all these gimmicks rather than having a proper fight.

Izuku continues anyway, asking why he rages like this, if he has any regrets, and if there is any other path he could go towards, referring to him as "Goto Imasuji", but Muscular simply responds he just wants to indulge in blood and violence and it's useless to try and sympathize with him.

Hearing Muscular's declaration, Izuku thinks back to his previous thought about how if he truly understood the villains maybe things would turn out differently, and how even if the fight now is inevitable, he still wanted to learn at least what makes him tick deep down. As Muscular breaks free from Blackwhip and tries to fight back, Izuku notes how the tendons in his Muscle Augmentation have started to unravel.

Muscular is shocked by this, and Izuku explains to him that his armor of muscles has weakened thanks to his initial battle with Grand and his vibrations, and that was the reason he was purposefully keeping his distance. Muscular screams in annoyance, as Izuku comes at him with a smash to the stomach, knocking him out with one punch, declaring that this is his full power.

Wrapping him up in Blackwhip, Izuku quickly flies away from the city, delivering the unconscious Muscular to the Daina Police Station, before again speeding off into the air to the officers' confusion. With Danger Sense calmed down, Izuku contacts All Might and meets up with him in an alleyway. All Might inquires about his condition, which Izuku says he's alright, thanks to his new support item that All Might ordered from America, the Mid-Gauntlets.

All Might reminds him that it is still a prototype and they were made for endurance, so they will reinforce his body but won't be able to handle 100% output, so he can't go overboard. Just as All Might receives a phone call from Hawks, who is fighting a Villain alongside Endeavor and Best Jeanist, asking about Izuku's status, he gets another alert from Danger Sense, and once again leaps away off toward the trouble.

As night falls and it begins to rain, Izuku comes to the rescue of a large woman with a mutant Quirk under attack by civilians who mistake her for a villain. He manages to calm them down and comforts the woman by telling her that everyone is scared, and he will make sure everything goes back to normal. After All Might arrives on the scene to take the woman to a shelter, he gives Izuku a box lunch which he happily accepts.

While observing the city, he converses with Daigoro Banjo, who compares what is happening now to what it was like during his lifetime. Izuku mentions that they still have no information regarding the League of Villains or Tomura's location, and that unless he can draw out all of One For All's full power, he will never be able to stop all the chaos. With all the successors now ready with their full support, Izuku once again prepares to head off.

Trying to get in contact with All Might, Izuku is shocked when his phone is suddenly shot by an unknown assailant from afar. With the phone pinned to a nearby building, a voice coming from the microphone attached to the bullet directly addresses Izuku, which he recognizes as an assassin sent by All For One, as she tells him to come with her and if he complies, he can keep his limbs.

He quickly realizes said assassin is former Pro Hero Lady Nagant, an incredibly skilled marksman who someone that even Snipe envied, and Hawks' senior at the Hero Public Safety Commission. Izuku recalls his earlier conversation with Hawks and his warnings to run if he encounters her.

Recovering his broken phone, Izuku tries to flee but is constantly shot at by Lady Nagant, who using her Quirk, Rifle, transforms her right arm into a rifle, along with using her pink and dark-blue hair to create any kind of bullet she requires, to blast at him from afar. Izuku tries to use Danger Sense, as well as Blackwhip to swing across the buildings, to avoid the bullets, but they continue to curve and chase him, as he's forced to try and block them head-on.

After thinking about how if it wasn't for Danger Sense he would've been finished by now, he is able to deduce the location of Lady Nagant based on where the previous shot came from, and decides instead of trying to endure the barrage and escape, to confront her directly.

He heads toward the building she is stationed on, zigzagging between the other buildings to stay out of her line of sight, until he is suddenly caught off guard by a bullet coming at him from behind, which he deflects, only for another one to graze his stomach. He is confused at how she was able to shoot at him from two different angles, and temporarily wonders if she has backup, until realizing what's really going on: All For One gave her another Quirk.

As she continues to shoot at him from the air, Izuku realizes that the closer they get, the more intuitively she can shoot, which means he won't be able to react fast enough to guard or dodge. Without any options, he lands and unleashes a Smokescreen at "Full Blast", filling the city with smoke. En re-appears to scold Izuku for releasing so much because once he emerges, he'll be easily exposed to her.

However, Izuku tells him he isn't planning on escaping, as En realizes what he's planning to do, leading him to advise against it. He is backed up by the third user, who recognizes that he is attempting to use his Quirk, warning him that he hasn't tested it out yet. Izuku tells him that he knows it's too late to properly train, but he can't waste this opportunity to stop Lady Nagant and force her to tell him where All For One and Tomura are.

Izuku uses several of his equipment, including Gran Torino's cape, his backpack, and his mask, to act as decoys to distract Lady Nagant long enough for him to activate the third user's Quirk, Fa Jin, releasing all the kinetic energy he built up in his body, allowing him to completely blast through a building, catching Lady Nagant off guard and managing to grab ahold of her arm.

While he tries to get her to tell him where All For One is, she proceeds to use her Rifle to punch him off of her, allowing her to escape and continue to shoot at him. He asks her why she's working for All For One since she used to be a Pro Hero, but brushes him off that he just doesn't understand the real truth. During the chaos, Izuku realizes that due to using Fa Jin for the first time, his parallel processes are screwed up, forcing him to attempt to readjust himself while still avoiding the shots.

Lady Nagant proceeds to explain her history with the Hero Public Safety Commission to Izuku, how she believed all she was doing was preserving the fake society by secretly killing rogue villains and corrupt heroes, and how she killed the former President after she was threatened for voicing her resignations.

Izuku is shocked by the revelation, since the news was that she had killed a fellow Hero in an argument, while she continues saying he's just ignorant, that a superpower society is an illusion and bringing back the status quo will have history repeat itself. Izuku, however, admits that while he had been ignorant in the past, he has started to realize the world isn't all black-and-white, but mostly shades of gray, and that is exactly why he needs to lend a helping hand.

As Izuku makes his way over to Lady Nagant's location using Blackwhip, she turns her Rifle to a man on the skyscraper above them, Kai Chisaki, who Izuku is surprised to suddenly see as well. Shooting the bullet directly at him, Lady Nagant plans to use Izuku's hesitation to catch him off guard, however to her surprise, he immediately swings himself forward toward Kai, using a combination of Fa Jin and One For All at 45% to create a sensation of "Faux 100% One For All", becoming faster than the bullet and knocking Kai out of the way.

After telling Kai they'll talk later, Izuku uses Blackwhip to realign himself, as using One For All at 45%, Fa Jin, Danger Sense, Blackwhip, Smokescreen, and Float all in rapid succession caused his parallel processes to get screwed up and needed to take a moment to readjust. Using the last bit of Fa Jin stored up in his leg, he utilizes a Faux 100 Percent: Manchester Smash to break Lady Nagant's Rifle before she can start shooting again.

As she starts to fall, Izuku grabs ahold of her, telling her that he recognized that the shot headed toward Kai was off, and that she could've shot him right from the beginning rather than give him a chance to surrender, meaning she's not truly on All For One's side. He tells her that because she's seen the darkness, she can also recognize the light, and asks her to join him since he still sees the soul of a Hero within her. As Lady Nagant smiles and starts to tell Izuku he is a true hero, she suddenly self-destructs causing Izuku to scream in fear.

Hawks soon arrives to catch the unconscious Lady Nagant, followed by Endeavor to back him up. Due to still not having enough feathers to fly and carry someone, Izuku uses Blackwhip to grab ahold of them but can't carry them due to running out of strength. He manages to tell them that Lady Nagant had received a Quirk from All For One and because of that, he believes that the self-destruction was part of a trap he implemented.

Landing on the ground, Hawks gets Lady Nagant to briefly wake up and inform them of the location she was supposed to deliver Izuku too, as well as warning them about other criminals All For One hired to go after him.

Endeavor returns carrying Kai, who berates Lady Nagant for not fulfilling her promise, as he just wants to apologize to his Boss. Hearing his pleas, Izuku confronts Kai asking if he remembers what he did to Eri, as he goes off saying he wishes she was here too. Izuku tells him he understands he wants to apologize, and that if he can direct those feelings toward Eri as well, he will honor the deal in Lady Nagant's place.

All Might arrives as the Heroes prepare to fully apprehend Lady Nagant and Kai, as well as deliver the former to medical aid, which Hawks also suggests Deku do as well, all the while he festers up with rage toward All For One.

Sometime later, Izuku, the Top 3 Heroes, and The Lurkers, locate the former Creature Rejection Clan's hideout in Haibori Woods. Despite Endeavor's pleas not to be reckless, Izuku enters only to find it abandoned, which Endeavor had anticipated. They're then faced with a pre-recorded message from All For One, taunting Izuku for expecting him not being able to abandon someone like Lady Nagant and falling into the trap.

He continues on about how society labels people who don't fit in as "villains", and that all the fights Izuku will have to deal with continue to wear his soul down. He concludes revealing that he was the only one he kept thinking about in prison, and that he no longer cares about All Might, stating it is "his turn", as the hideout suddenly explodes.

Shortly after escaping the explosion, the Pro Heroes regroup to plan their next move while Izuku continues his endless quest to hunt down the villains. He's soon attacked by another hired assassin, but almost immediately takes him down with ease. He quickly leaves the body behind, warning All Might to be careful in case he is rigged to explode, but before he can leap away, All Might yells at him to stop.

He tries to hand him another lunchbox, however Izuku tells him he doesn't need to follow him anymore, since he can practically move his body at 100% capacity without injury just like him, so he shouldn't worry about him. Despite All Might's attempts to reach out to Izuku and tell him to take it easy, he is left behind as Izuku heads off all alone.

Endeavor attempts to contact the lone Izuku, informing him that the foreign heroes should be arriving soon to assist and that he should take this time to rest, but he refuses to stop and continues his search for the villains. At the same time, the previous wielders of One For All also try to get Izuku not to push himself, but he also ignores them as he jumps toward danger.

He arrives at a mall where he protects a group of civilians from some thugs, but after they retreat, the woman cowers over Izuku's appearance, seeing his multiple Quirks and believing he's working for All For One. He quickly shoots that down, as they are nervously relieved running to safety. He continues running from location to location, whenever he receives a notice from Danger Sense, endlessly fighting villains and protecting civilians caught in the middle, with barely any sleep or eating time.

During his escapades, rumors begin to pop up regarding Izuku, with some believing him to be some kind of Nomu, and others seeing him helping people, although also noting he looks nothing like a hero, as his costume becomes more tattered and his Blackwhip more out of control, contributing to his monstrous appearance.

Meanwhile in his mind, all he can think about is tracking down All For One and the League of Villains, and doing everything in his power to save everyone, all so he can once again reunite with those he cares about, specifically his mother, All Might and his classmates, so he can smile with them again.

In the city, Izuku's exhaustion starts to get to him as he's confronted by the next assassin sent by All For One, Dictator. Using his Quirk, Despot, Dictator takes control of an army of civilians which he uses to attack Izuku. He recalls how he was previously defeated by Crust several years ago, and that in order to deactivate his Quirk, either the victims need to receive a large shock or Dictator be taken out.

However, unable to use Air Force properly without his gloves, nor Blackwhip for being too dangerous, the civilians dog pile Izuku as they apologize for attacking him, tearing off his costume. He silently understands, as he attempts to think of a way to help them, but slowly starts to fall unconscious.

Suddenly, Katsuki arrives on the scene, shooting Dictator with an AP Shot, and informs those on the other end of his phone that he's found Izuku. When the rest of Class 1-A arrive on the scene, he asks why they came and they answer that they wanted to help him. Izuku responds saying he is fine and for them to stay away, causing Katsuki to mockingly applaud him before asking if he can smile now. Izuku says that he needs to keep moving if everyone can smile again, and demands everyone get out of his way, prompting his classmates to fight him.

Izuku tries to use Smokescreen to make an escape, but Katsuki uses his Land Mine Blast to blast away the smoke, asking if he believes that now he's one of the big-shots if they're all just a bunch of "NPCs" to him. Anima uses his Quirk to command birds to halt Izuku, yelling that Nezu has asked him to come back and stop running away. He tries to use Blackwhip to free himself, but Cellophane uses his Tape to grab ahold of it, commenting how freaky it looks. Earphone Jack then uses her Heartbeat Wall, forcing him to jump away, as she tells Izuku how happy she was back during the Cultural Festival.

Tailman then arrives, grabbing ahold of Izuku with his Tornado Tail Dance, telling him that he'll never forget how frustrated he got for him during his fight against Hitoshi at the Sports Festival, and they all can't overlook how ragged he's become fighting alone. Izuku continues to insist that he'll put everyone in danger and he doesn't want All For One to take them away from him, which is why he had to leave.

Tsukyuomi appears next, using Dark Shadow to grab onto Izuku, knocking him into a building. Sugarman, after rescuing Earphone Jack and Tailman, yells at him that while he may have a special power, they all share the same feelings, and to think about what they said, or else he won't let him use food coloring for Eri's candy apples.

Still attached to Dark Shadow, Izuku is suddenly restricted by a machine created by Creati, who says that they've been authorized to use their Quirks to help Endeavor and the other heroes, with the intention to join him and ensuring his safety. Recognizing it's a machine to put him to sleep, Izuku breaks free, yelling at them to stop wasting their efforts on him.

Chargebolt grabs ahold of him next, telling him that even though One For All is important, and they may not have any hobbies in common, he's still someone he considers a friend so he will force him to listen. Tentacole uses his Dupli-Arms covered in Insulation Tape created by Creati to cover up Izuku and Chargebolt, reminding him of Izuku's words during the Training Camp how everyone together can even give All Might a scare.

Tsukuyomi finishes it off by using Dark Shadow to completely entomb the two with Ragnarök: Womb, reminding him how using Dark Shadow's offensive power as defense was his idea as well. As Chargebolt sends his electrification through the containment, Izuku still manages to break free, blasting away from the building. Fighting back tears, he thinks about how he knows everyone is truly worried about him, because Danger Sense hasn't alerted him at all, but still continues to shout and insist he's fine.

He suddenly smacks right into a Heaven-Piercing Ice Wall, as Shoto looks down on him, seeing his broken face, telling him to let them share his burden. On a building close by, Froppy appears to be shedding tears and tells him that it's okay to cry when you're scared, and that if he wants to remain strong like a comic book superhero, they won't let him go at it alone.

Shoto yells to Izuku that his current state is part of All For One's plan and could take the opportunity to attack U.A., so he should consider a backup plan if he hasn't been able to find him: to protect the school by letting them all fight alongside him. But as All For One's words continue to ring in his head, Izuku refuses, yelling that this is a fight between One For All and All For One, and the others can't keep up.

He breaks free of the ice attempting to flee, when Grape Juice latches onto him using a chain of balls. He cries that he never thought his power was what made him awesome, and what made him so cool to him was how he led everyone to victory despite being scared himself. Izuku, however, says that that version of him is gone, striking Grape Juice with Blackwhip, slamming into a nearby building. Izuku prepares to make a getaway using Faux 100 Percent, but Uravity comes from the sky, trying to grab him and tell him the situation is different, desperately trying to ignore her words as he dodges her and blasts into the air.

Nearly escaping his classmates, Ingenium suddenly appears to grab ahold of his hand, having been blasted through into the air through a combination of nearly everyone putting their abilities together to push him forward. Izuku demands he let him go, but Ingenium refuses, saying that Ingenium is the Hero who will grab the hand of a lost child and repeats Izuku's earlier words to him, that giving help that's not asked for, is what makes a true Hero.

Finally starting to break down, Izuku tries to break free of Ingenium's hand, but doesn't have the mental strength to let go, just as Uravity deactivates her Quirk, causing both of them to fall out of the sky. Thankfully, Red Riot is there able to catch them. He then tells Izuku that he remembered an old story on the news about a kid his age that rushed to save a friend from a villain, and figured it was him that day. He says that being a Hero has nothing to do with being special or strong, and his behavior from back then is what everyone else is doing now.

Everyone else catches up as Pinky tells Izuku she doesn't want to lose anyone anymore, and to return to U.A. so they can have classes together. Izuku stands up and says he wants to come back but considers it too dangerous for all the people already there, and he says he can't go back to the way he was before.

Katsuki walks over to him though, and asks if he remembers what he said when he got stabbed by Tomura during the war. When Izuku says he doesn't, Katsuki reminds him that he said "stop trying to win this on your own," and continues telling him that in that moment, his body had moved on its own. Katsuki admits he looked down on Izuku because he was Quirkless, and therefore he felt he would be far behind, but the truth was, he always felt he was above him.

Katsuki tells him that he couldn't accept the way he was, which led to him bullying him over the years and trying to prove his superiority, but after entering U.A., he kept losing, and he started trying to understand Izuku's strengths and his weaknesses. Katsuki tells Izuku that even if it doesn't change anything, he has to speak his current truth: He apologizes to him for everything he had done to him up until now, even calling him by his first name.

Katsuki's words snap Izuku to his senses as Katsuki tells him that his choices weren't misguided, but he can't handle it by himself anymore. If he encounters a hurdle, he can rely on his friends to help him, and the only way to surpass All Might is for everyone to protect U.A. and the civilians together. Izuku weakly collapses and apologizes for what he said about everyone not being able to keep up with him, which Katsuki accepts as he catches him.

When Izuku wakes up, he is greeted by the face of Thirteen, and the front of the massive U.A. Barrier that encompasses the entire surrounding school area. Thirteen informs Izuku how most of the civilians have been evacuated to various centres, with only the anti-hero vigilantes and violent pillagers left to deal with, though also notes that those numbers have been dwindling due to the anti-hero civilians' exhaustion and the pillagers being easy to catch. She also thanks Izuku for everything he did to help on his solo journey.

Being let down by Mezo, Hanta tells Izuku about some of the Barrier's security features, with Toru adding it can even combine to Shiketsu High. Izuku still believes he can't go back, and his beliefs seem to be enforced by a group of protestors within the school demanding he not be let in. The civilians say they know he is the rumored boy Tomura is after and since they were convinced by Nezu U.A. would provide them guaranteed safety, allowing what they consider a "ticking time-bomb" in is a horrible idea. They say he should go somewhere else and Izuku even considers leaving, but Ochaco grabs his hand to stop him from leaving, and tells him not to worry.

Despite Best Jeanist's attempts at reassuring the civilians by informing them of Izuku's purpose in their plans, their hatred and anxiousness continues to boil over, overloading Izuku's Danger Sense. Suddenly, Ochaco floats her way above the crowd toward the top of U.A., where she gives an impassioned plea to let Izuku stay. She lets them know that he has a special power that can stop the villains, but he's also been running himself ragged all by himself, begging them to look at him and let him stay.

As Izuku remains speechless through her proclamations, Katsuki turns to Izuku and reminds him that he and the others will step up when he can't handle things alone, and Tenya tells him that everyone is fighting, including Ochaco, causing him to start to tear up. Ochaco concludes her speech declaring to the crowd that Izuku's just a high school kid and that it's up to everyone else to help when the heroes are hurting. All her words cause Izuku to finally break down in exhaustion and relief, collapsing to his knees and crying hysterically.

Kota and the mutant girl Izuku had saved several days earlier rush their way out of the crowd to comfort him. Kota apologizes for being too scared to run but after hearing Ochaco's words, he knew he had to move, tearfully telling him not to cry anymore because he's here. The girl picks Izuku up and tells him that she had been refused by several shelters for being a Mutant, but she's glad she ended up at U.A. because it meant getting to see him again, as the two give him a hug.

As the civilians look on and see Izuku for who he truly is, they discuss amongst themselves about what they should be doing and how they must become more than mere "spectators" now. One of the boys turns to Izuku, talking about the rumors of a man dressed in rags with multiple Quirks who's either a villain or "true hero", asks if him staying will give them back all the lives they once had. Izuku confidently responds that now that everyone's together with him, he will bring it all back. The civilians agree to let him stay as they and his classmates escort the tired Izuku inside.

The boys of 1-A immediately rush Izuku to the bath, stripping and washing him thoroughly before throwing him in and joining in with him. Katsuki yells at everyone for poorly scrubbing him before jumping in himself, as Fumikage states that even after his heartfelt apology, he still hasn't changed. Katsuki, however, reminds everyone that his goal to become number one hasn't changed, which makes everyone his rivals still, including Izuku, who he tries to refrain from calling him "Deku." Izuku tells Katsuki that he doesn't have to force himself and can still call him Izuku.

After the bath, Izuku learns that Ochaco has fallen asleep after her speech, as well as some others too, with the rest of his classmates drying off in the common room. Izuku once again apologizes for the trouble he felt he caused and they forgive him, while also asking some questions about One For All. Shoto tells everyone to leave Izuku be so he can rest, but Izuku tells him he feels he can't, at least not until he apologizes to All Might for pushing him away.

Suddenly, All Might appears in the dorm and apologizes himself to Izuku for not helping him enough, despite Izuku's protests. After All Might tells everyone he has gained new information to help them in the fight, Izuku speaks up and tells him that the food he made for him gave him strength, and chalked his hardships to not having him at all. Now, they all will fight for what they love together. All Might promptly leaves to regroup with the other Heroes, as Izuku finally passes out on the couch, where Shoto covers him up in a blanket.

U.A. Traitor Arc
Two days later, Izuku and the rest of Class 1-A learn that during this time, Tomura had fought American No. 1 Hero, Star and Stripe, and while she was killed during the battle with Tomura successfully stealing her Quirk, New Order, thanks to her actions, the Quirk acted like a virus within his body, destroying several of his Quirks and delaying his procedure by about a week. All Might informs all this to the class, telling them that this is now their perfect time to prepare for the inevitable all-out war.

Katsuki yells at All Might that they've already been preparing, with the rest of the class revealing 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. Izuku says that Katsuki and the others agreed to practice with him to help master One For All, but Katsuki barks back at him, just like he usually does, claiming he only wants to test out his new Cluster moves on him, to his shock. The rest of the class each respond with enthusiasm as they all prepare to go out and train, with All Might looking on proud and satisfied.

In the courtyards in front of the school, Class 1-A train amongst themselves, with Izuku and Katsuki sparring between each other. He talks about how he's starting to learn how to focus on saving sweat for a barrage of explosions rather than one big explosion, while Izuku also notices Shoto going for a different approach, working to make his both halves into one.

The class proceed to discuss about how they'll be able to deal with Tomura and All For One, specifically how they have no way of tracking down All For One, that they only have half of the Heroes remaining from the previous battle, and that the villains are the ones with the edge on deciding when the battle starts. Izuku says that it is because of that they need to try and dictate how they enter the fight, and that he's going to rejoin the search soon, before being reprimanded by Tenya, reminding him that "we" will be rejoining the search.

Looking around, Izuku asks if he can go for a quick stroll, which Tenya says is okay as relations between the Heroes, students, and the evacuees have grown warmer since Ochaco's speech. Izuku goes out into the woods looking for Yuga, who had gone missing and who he had noticed was acting weird ever since he came back to school. He ends up running into a panicking Toru who was also looking for Yuga and overheard a conversation between him and his parents revealing a devastating truth: Yuga is the U.A. Traitor.

It turns out Yuga was born Quirkless and his parents approached All For One who gave him his Navel Laser Quirk, though now also putting the family in his debt. Izuku and Toru approach the Aoyamas, telling them he heard the details from Toru. The parents try to feign ignorance, while Izuku tells Yuga that he noticed how gloomy he's been looking, believing something is wrong, and came looking for him. After hearing these words, a tearful Yuga sorrowly admits to Izuku that he was the one who helped the League during both the U.S.J. Incident and the Training Camp, declaring himself a "despicable villain."

With the truth revealed, Yuga's parents attempt to escape with their son, while Izuku and Toru give chase. Yuga tells Izuku that after reading his letter and finding out he too was Quirkless, he fell into utter despair. Izuku's Danger Sense goes off as Yuga prepares to fire at him with a Navel Laser, with Izuku ready to defend, but Toru jumps in front and refracts the laser away. After Toru confronts Yuga about how his actions have affected everyone, with the parents trying to rebut, Izuku uses Blackwhip to restrain all three of them, with him telling Yuga for them to put an end to this now.

The Aoyamas are taken to the U.A. A.V. Room, where they are interrogated, by All Might, Naomasa and the Police Force, the U.A. Staff, and Class 1-A, all who are devastated by the betrayal. Among everyone's reactions, Katsuki simply states that it's a "small world" that he's another one of them that started out as Quirkless.

The parents explain how they know nothing about All For One, only carrying out his orders, fearing for their lives if they disobeyed, while Yuga himself confesses, feeling that he is terrible for having the nerve to try and smile with everyone like they were friends after everything he's done. Especially after seeing Izuku, another former Quirkless person, fighting so hard against All For One, made him realize how pathetic he was, wallowing in his own despair, and that he's just a villain through and through.

However, Izuku bluntly retorts, asking if that was true why he tried to save Katsuki and Fumikage during the Training Camp, as well as asking about his cheese message, now realizing that it was a cry for help, and that's why he's crying now. He continues that he knows of another Hero who was manipulated by All For One, but her soul wasn't crushed, only her spirit. He states that doing wrong doesn't make you a villain for the rest of your life, as he extends his hand to Yuga, telling him he can still be a hero.

Naomasa dismisses Izuku's pleas, reminding him that no matter the circumstances, he still conspired with All For One, and even then, they still aren't sure if he's booby-trapped like Lady Nagant was, so they can't allow him to talk again until he's examined at Central Hospital. He continues to interrogate the Aoyama parents, only for Izuku to cut him off, reminding them that they have no way of locating All For One. This causes his classmaes to remember Izuku's point about "steering the villains" to enter the fight, realizing Yuga may be the only one able to deceive All For One.

Present Mic asks Class 1-A why, with them being the greatest victims after all this, they're so willing to trust him, but Tenya simply responds that what happened is in the past, and with them being unable to realize how he's been feeling all this time, they carry some responsibility, so they must reach out to him as friends in order for them to become equals again. Eijiro also yells to Yuga that while he may have thought it was impossible to against All For One, now Izuku has given him and his parents a chance to finally break free from him, reminding him that they would never blame someone for being Quirkless, or would hate them for holding back their tears and hiding their pain in secret.

Naomasa reminds the class that the Aoyamas already told them All For One won't believe any lies so they need to keep a level head, when Izuku is called on by Shota Aizawa, watching from a tablet held by Present Mic. He asks Izuku if he has a plan, which he says no, followed by him addressing Naomasa, taking full responsibility for also not recognizing and siding with the rest of the class, informing Yuga he has no intenion of expelling him from U.A.

Shota reveals that he has an idea, and after the Aoyama Family's ears have been covered, he informs Class 1-A, the U.A. Staff, and the Police Force of his plan. After the discussion, Nezu states that it seems possible, while Naomasa has the Aoyama Family escorted back to their HQ, telling everyone not to say a word to anyone else about the plan. Before he leaves, Izuku shouts out to Yuga, with the rest of the class looking on sullenly.

Back at Heights Alliance, Class 1-A take a breather, before getting ready to gear back up, as everyone, with fire and rage in their eyes over the betrayal, prepares to bring All For One down once and for all. Izuku and Tenya go to the Development Studio in order to fix up their hero costumes, when Izuku is suddenly caught in a very familiar explosion blast. Mei Hatsume emerges from the smoke, once again landing directly on top of Izuku, as she asks him what he needs, all the while his face keeps a stern expression.

Mei asks Izuku and Tenya what they need from her, with Izuku lamenting how his Danger Sense didn't activate. Tenya tells Mei they came looking for repairs for their Hero Costumes with her confused why they don't just take them to the item agency. Mei's increasingly nonchalant reactions cause Izuku to realize that Mei has no idea what is going on outside.

Power Loader emerges from the explosions, inviting the students to see the new set-up in the Development Studio, revealing they are in charge of both developing and controlling the U.A. Barrier. Izuku hands Mei his Mid-Gauntlet, asking if she can fix it for him, but she immediately says no, as due to how damaged it is she'd have to create a new one, and they don't have the amount of condenium required for the compression mechanism. She also quickly shuts down Tenya's requests as well, as two of her classmates approach them saying they'll make it.

Tenya is surprised that Mei would turn down the offer due to how much she loves making things, as Izuku looks on to see her currently working on the evacuation shelter blocks. Power Loader tells them that Mei was brought on to help strengthen the barrier, and she's been busy creating new mechanisms in case of mass evacuation. Power Loader compliments her inventive mind, and she responds with how she always needs to try think up new "babies" to improve themselves.

Izuku compliments Mei on how focused and busy she is with her inventions that she had no idea how the outside world is, but Mei responds calling him dense, saying that even she is aware of the trouble Heroes are facing now. And while they aren't fighters, they're also doing everything they can to protect people; inventing stuff being how the support course does heroics.

Before Izuku can react, Mei throws a pair of Air Force Gloves attached to new make-shift Gauntlets right at his face, saying that she couldn't make an exact copy but it's the best she can do, surprising Izuku that she did that all with just her left hand. She proceeds to throw a new piece of armor for Tenya right at his face too, exasperating the support students that she did it all so fast. She concludes saying for them to tell the rest of the hero students that they'll all win this.

Outside, Izuku and Tenya meet up with the rest of Class 1-A and Mt. Lady, who reminds them that even after learning what they just dealt with, their main objective is tracking down and eliminating the remnants of the villains, and they must do it all without haste. Mina wonders if Yuga will still take their hand and help them, with Izuku and Shoto replying that they believe he will come back. Following Izuku, the Class 1-A Search Squad assembles and heads out.

Later that night, Class 1-A ended up with nothing and no information about the villains' whereabouts. After returning to Heights Alliance, Izuku laments the lack of any free time given to them due to the number of prisoners still being on the run and the whereabouts of All For One. As his class takes a break, he thinks about how he hasn't been able to thank Ochaco properly yet. All Might, alongside Naomasa and Nezu, then burst into the dorm, to inform them all about their secret finalized plans for the upcoming second War.

They explain to the class the full extent of their plans: that they have purposefully been running themselves around to make All For One, who is presumably observing them through Search, believe they are being exhausted, allowing them to catch him off guard and utilize Yuga to choose the location to lure him out. Class 1-A, especially Izuku, react in joyousness over Yuga's involvement, but when asked about how to get around All For One being able to perceive their lies, they bring in Shota's next part of the plan, Hitoshi Shinso.

To the class' further surprise, he reveals that he has trained his Quirk to allow himself to be able to make people speak when Brainwashed, and that they can use this in order to get the Aoyamas to communicate with All For One without effecting their emotions. When asked about what happens after they lure the Villains out and if its possible to deploy all the Heroes without being found out, All Might states the Heroes don't have to be there in advance, revealing Shota's next piece to use Neito to Copy Kurogiri's Warp Gate.

They proceed to assign each of the students to different teams to face down the villains, with Izuku obviously chosen to deal with Tomura. During their bath after the discussions, Izuku talks to Shoto about his worries for him fighting Dabi, but he tells him it's his decision, and he needs to face him himself. Shoto then shows off his new technique, Flashfire Fist: Phosphor, which gets Izuku really excited. After explains how it works, Shoto turns to Izuku, now feeling more confident in affirming the reason why he was born in his family, thanking him by repeating the words he said to him at the Sports Festival, that it is his power.

The next day, Nezu announces to the civilians within U.A. that Tomura will make his big move in 4 days, with Class 1-A giving their thanks to everyone at the entrance, and Izuku saying he's had more than enough time to clean himself up, with them all ready to head back out. Class 1-A each say goodbye to their family members and their friends. Izuku reunites with his mother Inko, Kota, and Eri one last and final time before heading out.

Class 1-A reconvenes at the Makeshift Fortress dubbed, "Troy", a fortified structure where they can stay at. After moving in, Izuku spots Ochaco reflecting outside and jumps down see her. He thanks Ochaco for what she did earlier, which she simply brushes off, before saying she's just watching the city. She proceeds to tell him she feels weird, as back when she was shouting from the top of the building, Himiko popped into her head. She tries to brush off her feelings by thinking of all the wrong they've done, but Izuku replies that he understands her, having seen a little boy crying inside Tomura, and that even though there's no way to avoid the battle, he can't ignore that side of him.

Final War Arc
Izuku stays with Class 1-A at Troy until he is contacted by Yuga and agrees to meet him at a disclosed location in a parking lot nearby. He asks if he's supposed to be detained, and Yuga says his parent's lawyer had him released. Yuga proceeds to tell Izuku about All For One's true goals: to become the Demon Lord of the world after chaos spreads throughout the world unchecked. With Japan fallen, the economy is shattered, alongside the various villain attacks all over the world, facing such immense crisis since the Great Depression, or even the period of the advent of Quirks, chaos has already begun to spread unchecked.

Izuku declares he will never let that happen, with Yuga apologizing, as All For One finally re-emerges from behind him. All For One congratulates Yuga and prepares to attack Izuku, when Yuga overcomes his greatest fear and betrays against All For One, hitting him with his Navel Laser. Izuku deploys Smokescreen to cover Yuga, telling him how good his performance was that they managed to trick him. Annoyed, and since using Search he can tell all the Heroes Tomura faced are miles away, All For One uses his Warping Quirk to summon an army of villains to overwhelm One For All once and for all.

However, All For One is once again taken aback when he spots Kurogiri's Warp Gate starting to appear behind them, with Neito Monoma appearing from one of them. As the rest of the Heroes begin emerging from the gates, Yuga declares to All For One Japan isn't finished with them, and that today is the day where he falls.

With all of the villains in one place, All Might activates the Troy system as cages emerge from beneath the battlefield, trapping all the villains in individual metal containers. Neito summons several more Warp Gates around the cages, as the Heroes prepare to shove them all in, to split up the villains. Izuku blasts all of the villains with Air Force to push them all through new Warp Gates. However, before he can follow Katsuki into his Warp Gate to face Tomura, he is suddenly caught off guard by a whip, forcefully dragging him into a separate Gate, to his confusion.

Izuku ended up getting warped to an aquarium in Okuto Island, alongside Ochaco and Tsuyu, by Himiko using her whip. He is confused that his Danger Sense didn't even activate, staring down Himiko. He contacts the U.A. Flying Fortress where he was supposed to be in and asks for a Warp Gate at his location, but Shota reveals that he and the other heroes cannot help him due to the new abilities of Tomura despite Neito using Erasure on him to keep the villain from using his Quirks. He tells Izuku that he is on his own to find a way back to the mainland. Before he can leave, Himiko ambushes him, declaring her love for him and asks Izuku to not go. He is still surprised that even when she's charging at him, his Danger Sense isn't activating, wondering how someone like her could get so far in life. Izuku asks what she wants as Himiko tells him to be her boyfriend, leading to confused reactions from him and Ochaco.

Izuku freaks out with flabbergasting reactions, asking what she's talking about, leading Himiko to confess she's felt this way ever since they first met, since he was so beaten up and looked exactly like her first crush, her face twisting saying she wants to suck his blood and become him.

Himiko asks him what he wants to do with her, and Izuku responds by saying that he too wanted to become like All Might, and that he understands her, and how fulfilling it feels. However, he proceeds to say he could never share the same heart and mind as him or think about hurting the ones he love. Enraged, Himiko attacks him and Ochaco with her knives and whips, with Tsuyu and Ochaco holding their own against Himiko. Ochaco tells Izuku to leave now to deal with Tomura, and to trust in them to handle Himiko. Izuku nods in agreement and speeds away.

Using Float, Fa Jin, and his Air Force, Izuku blasts his way across the ocean, however laments that he is still too slow, noting that there's nothing for Blackwhip to sling off of, so he is unable to use his Faux 100 Percent technique. He thinks about needing to get faster, when the Second User of One For All appears telling him not to lose his cool.

He reminds him his gear can't withstand using One For All at 100%, asking if he plans on hurting himself before he even reaches the battlefield. He then asks if he tried to activate his Meta Ability, which Izuku responds yes to. He tells him that it is only to be used as a last resort, as after melding with One For All, it has evolved into a "unique power" and something which can't be wielded like it used to. He tells him to believe in his friends, who are all out there for their own reasons, and to focus on his own battle.

As Izuku continued to travel across the ocean, Yoichi senses something and informs him that he has a bad feeling, much to his surprise, when multiple figures start to appear in the distance. These turn out to be the American fighter jets, planning to escort him back to U.A. As he uses Blackwhip to sling to the side of the jet, the Bravo Leader informs him they were meant to defend the aerial space around U.A., further saying that they've remained in Japan even despite their orders to retreat because "their gal" decided to wager everything on him, having inherited All Might's power. The fleet proceeds to create a path of jets for Izuku to swing off of, telling him to go so he can take down the greatest villain once and for all.

Izuku eventually makes it to the Flying Fortress, using Blackwhip to cling onto two poles outside, waiting for the electromagnetic barrier to be opened. Once it finally is, after Mirio is able to distract Tomura for long enough, Izuku prepares to slingshot his way in, as he and Tomura both exchange glances, releasing himself right into Tomura with a Smash.

Arriving in the battlefield with the barrier closing, Izuku apologizes for being late and asks if everyone is okay, only to be stunned into silence after witnessing an unconscious Katsuki lying on the ground. Seeing the other barely conscious Heroes around sends Izuku into a further induced stress, all the while Tomura mocks him for his tardiness, figuring that Himiko had something to do with it, and asking if he has any excuses or reasons to run away from his responsibilities like everyone else.

The fear and rage over everyone starts to once again overwhelm Izuku's emotions as his Quirks begin to spiral out of control, unable to move. As Tomura begins to make his way over to him to take advantage of his current state, Mirio re-appears to Izuku, attempting to talk some sense into him. He tells him that everyone is still breathing and that Edgeshot is saving Katsuki's life, so they need to keep on fighting because they haven't lost anyone yet.

Tomura claims it's all merely "empty talk" to avoid facing facts and reality, but Mirio continues that as Heroes, they have to talk the talk in order to turn their ideals into reality. Remembering back to All Might's words of encouragement, and Daigoro's words to keep his emotions under control, Izuku calms down and comes to his senses, apologizing to Mirio. He then turns to the villain, calling out to "All For One", and with the One For All vestiges backing him up, asks if Tomura is still in there.

In response, "Tomura" claims that he no longer exists, that Tomura and All For One have fully merged into a new being, with All For One primarily in charge, telling the hero that despite whatever he's scheming, he won't get his ideal ending. However, Mirio retorts back, telling Izuku that when he spoke harshly to him, it caused him to throw a fit as if he were a child, and the more he was provoked, the more unstable he became, figuring he isn't as "fully merged" as he believes. Looking at the disembodied faces of the Shimura Family on his left arm, Nana sees Kotaro's looking at her, causing her and Izuku to realize he's still in there.

With all his power, "Tomura" jumps into the air, shaking the entire Fortress, charging at Izuku and 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 boosted binding combo, Blackchain, wrapping it around "Tomura's" arm and sending him flying.

"Tomura" attempts to try and restle the chain off, only to be surprised when Izuku undoes it himself. Concentrating to himself, the Second User tells him to make it quick, because once he starts using his Quirk, they need to finish him off in five minutes or the world is doomed. Izuku activates the Second User's Quirk, Gearshift, powering his Ultimate Move, Transmission, where in the blink of an eye, he appears under "Tomura", punching him with Second Gear, Third Gear, and finally Top Gear, sending him flying upward. Thanks to the Quirk's ability to let the user 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.

Thanks to Gearshift's significantly increased power after melding with One For All, Izuku is able to greatly enhance his speed, and unleashes a Detroit Smash: Quintuple at "Tomura", revving around the arena too quickly for him to defend. The villain tries to predict where his next attack will be, but at the last moment, Izuku shifts into Low Gear, causing "Tomura" to miss the swing, as the Quirk is able to adjust speed while ignoring the laws of inertia.

"Tomura" attempts to counter, 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.

Thinking about everyone that has been injured in the battle, Izuku declares that he's giving it all he got, telling All For One he won't let him hurt anyone else, pounding "Tomura" 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. He continues that what Mirio said is correct, that the course of the battle, and the events that led to this moment, has shaken the balance of their melding. The Second User tells Izuku to remember what Nana said and not to take it easy yet, as he attempts to recover. Just then, "Tomura" screams out, as the Heroes realize he still isn't done yet.

Meanwhile, Shota, Manual, and Neito were caught off guard by the sudden arrival of Kurogiri who teleported himself and Present Mic from a Warp Gate, alongside another portal containing Twice Doubles conjured by Himiko that begin to swarm them.

The Doubles proceed to attack Manual and Shota, and dogpile on Neito, causing him to shut his eyes and undoing Erasure. As a result, Tomura unleashes a massive explosion, destroying most of the U.A. Fortress. With the power line busted and the electromagnetic barrier barely standing, Mandalay then reports in that someone has hacked into their system and they have lost control of the flight system, causing the fortress to be on the verge of falling to the ground, warning them of what will happen if Tomura escapes.

Izuku notices a Warp Gate beginning to emerge near Tomura, realizing it is Kurogiri and wondering what happened at Central Hospital. He also sees after Tomura's explosion, his body has started to molt away, like as if he is shedding his skin. Tomura then surprisingly addresses Izuku, asking what he is going to do if he said "he's here now", telling him they aren't going to have a chat at the mall, since he's his villain. Izuku realizes that Tomura's original persona has emerged.

He begins to worry about how he needs to stop U.A. from crashing to save everyone inside, but also needs to keep an eye on Kurogiri so Tomura won't escape. Due to the immense power after using Gearshift, he finds it harder to breath, as he knows when his cells don't get a moment to rest, his body won't get enough oxygen and will be at risk of breaking down.

The Second User reminds him he can't fall yet, however, he continues that there is a silver lining, as thanks to One For All and All For One resonating with each other, they can see "inside" each other, and can see All For One currently unable to manipulate Tomura's body. He tells Izuku to do whatever to make his body act, as the chain of events leading to this moment will be his power.

As both Izuku and Tomura attempt to regain their bearings, Tomura's words continue to ring through Izuku's head. As U.A. continues on a collision course downward toward the city, suddenly they are saved when U.A. is stopped in the air through what Mandalay describes as a "trampoline in the air". Izuku immediately realizes what she is talking about, and happily cries out to Gentle. The reformed criminal had joined the fight and used his Ultimate Move, Gently Super-Lover, to prevent U.A. was plummeting, while La Brava worked alongside the Police Force to hack back into the systems.

However, Daigoro warns Izuku that Tomura has started to move again, and even though they averted the crash, if he touches the ground it will all be for nothing. Tomura finally gets a handle of things again, and prepares to make the first move by touching the ground with his Decay, however before he can do so, a speeding bullet is suddenly shot out of nowhere and hits Tomura, splitting his right arm off. Izuku recognizes the shape of the bullet, and is greatly surprised to see another former enemy has returned to aid them: Lady Nagant. Lady Nagant also proceeds to shoot his left arm off as well, giving Izuku enough time to recover.

With All For One's control of Tomura losing grip, he tries to command Kurogiri to transport him to his other self at Gunga, but "Kurogiri" begins to stutter, failing to comply. Tomura manages to regain complete control of his body, revealing that he kept his "origin" hidden deep within All For One so that it could fester and reclaim control in defiance of All For One's attempts to absorb him. Tomura decides that he doesn't need One For All and that he won't be controlled anymore, vowing that his heart will never waver. Tomura tells Izuku that "Tomura Shigaraki" and "Tenko Shimura" have one and only hope: the destruction of everything that stemmed from the abusive house he grew up in and will stop at nothing to eradicate everything associated with it, which will be the only thing that will save him.

Just then, Izuku grabs Tomura and blasted the both of them outside of U.A., as he thinks about how since Tomura can use his Quirks again, he can't fight him in the "tomb" anymore. Landing on the ground near the city ruins, Izuku states that while he won't let him do that, he also can't pretend he didn't see him crying back there, as both archenemies prepare themselves to fight once again.

Unknownst to him or Tomura, the students from the Hero Business Course were recording their brutal battle from above at the U.A. Flying Sky Fortress, as Izuku disables his Blackwhip to charge right at Tomura in full speed.
