Template:Shoto Synopsis/Final Act

Dark Hero Arc
Returning back to Heights Alliance after recovering from their injuries, Shoto, along with the rest of Class 1-A, each receive a letter from Izuku telling the truth about his Quirk and how Izuku has left U.A. due to being All for One's target. A few days later, Class 1-A discusses Izuku's letter and they come to the conclusion that Izuku is currently working with Endeavor, Hawks, and Best Jeanist.

When asked if they could confirm Izuku's location and safety with the top 3 heroes, Shoto, Fumikage, and Katsuki all confirm that their respective mentors aren't answering their phones. A few days later, impatient with their response, Class 1-A pushed forward using Endeavor's U.A. Alumni status to confront him despite knowing how much he does not like to be tricked.

Shoto asks Endeavor why he has been ignoring him and if he forgot the promise they made to stop Toya together. Endeavor tries to claim that his willingness meant a lot for him, but Shoto stops his father and says its not enough for him and Izuku shouldn't be an exception and proceeds to ask if he is letting Izuku and All Might work together. Endeavor refuses to answer which is enough to tell Shoto and Katsuki. Katsuki then tells Endeavor that Izuku will never take his own health into consideration. With Principal Nezu's permission, Class 1-A moves out to bring Izuku back to U.A. since he is welcome to come back.

Once Principal Nezu gives Class 1-A permission to bring back Izuku to U.A, Shoto joins Class 1-A to search for him while at the same time, apprehending any prison escapees along the way. After a month of trailing in Izuku's whereabouts, Class 1-A finally arrived on the scene to find Izuku in the midst of a battle between him and the villain Dictator. Shoto uses his ice to freeze the villain and Momo conjures restraints to subdue Dictator while Tenya, Katsuki, and Ochaco confront Izuku about his behavior. Izuku attempts to make it clear to everyone he is fine but his statement falls on deaf ears.

Class 1-A attempts to subdue Izuku only for him to use his superior strength and speed to escape. One of these escape attempts lands him right inside of Shoto's Heaven Piercing Ice Wall. Shoto remarks how he notices Izuku's unhappy face and feelings and wants him to share his problems with his friends. Shoto remarks that his desire to stay away from U.A and not rest could be playing into All For One's hand which makes U.A an easy target. Shoto states that U.A. could be protected if Deku returns. Deku ignores this and states the conflict is just between All For One and One For All.

Though Class 1-A continues to try and reach Izuku, he tries to ignore them by using his full speed to escape. Before he can, everyone uses their abilities to help Tenya catch up to Deku, including Shoto using the Heaven Piercing Ice Wall and a slope for everyone and he uses his Flashfreeze Heatwave to propel his classmates forward to gain some starting momentum to help them catch Izuku. He joins up with the rest of Class 1-A and listens to Katsuki apologizing to Izuku before he collapses from shock and exhaustion. With Izuku safely secured, they escort him back to a heavily fortified U.A High where Class 1-A is confronted by angry protesting civilians, who figured out that the villains are hunting down Izuku.

Due to the civilians' anxiousness, Shoto stays outside the Barrier alongside a disguised Endeavor and Hawks, while the Heroes inside try to convince them to let Izuku rest. Ochaco gives a speech and plea to everyone that finally lets them agree to let him stay, as Shoto, Endeavor, and Hawks are invited inside by Ectoplasm, with the chaos having died down. Seeing Izuku escorted inside, and the civilians now supporting each other, Shoto turns to his father and tells him they're going to "do it" together, thinking back to Toya's face, which he solemnly agrees.

Izuku is immediately thrown into the bath where the 1-A boys thoroughly wash him down. After they finish, his classmates ask him various questions regarding One For All, when Shoto appears and tells everyone to leave Izuku be so he can rest. Izuku tells him he feels he can't until he apologizes to All Might for pushing him away, only for Shoto to notice All Might peering into the window.

All Might enters and the two of them apologize to each other, as everyone proclaims they'll work together to fight back together. All Might then leaves the group to meet up with Endeavor and the rest of the Heroes, who Shoto says isn't at the school due to wanting to keep a distance between the civilians because of Dabi's revelation. By that point, Izuku had finally fallen asleep as Shoto gives him a blanket, also saying he feels he may be a cause for concern for the others due to being Dabi's brother. Eijiro says that he is going through a lot even though he views him as innocent, but Shoto corrects him saying his hatred of his blood blinded him to his origin, but he feels he has changed and wants to prove it so no one will be concerned for him anymore.

Kyoka thinks about Shoto's words about the evacuees not having a full change of heart yet, dragging Denki, Fumikage, Katsuki, and Momo closer to her, stating that just like the last time there were other people that regarded them with apprehension, they need to do something to reassure them and bring smiles to their faces, just like they did at the Culture Festival. Class 1-A comes back together, as they declare they won't just bring the world back to how it was, but to make it a better place than before, and do it all together.

U.A. Traitor Arc
Two days later, 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. The class reveals over the past month they had been training with the Wild, Wild Pussycats in order to keep up with Izuku in the incoming conflict, and are now about to head out to continue their training.

The class train amongst themselves out in the courtyard, with Shoto finally achieving equilibrium, matching his control of his left side with his right and continues to practice on making both halves into one power so that Dabi cannot burn his body. While training, he alongside everyone else received news that Izuku has captured the Aoyamas and was informed of Yuga being confirmed as the traitor who isolated the class at the U.S.J. and revealed the location of their training camp.

Once the Aoyamas are restrained, he and the other class bluntly refuse to back down from the news despite Nezu's request, all in stunned and tears of Yuga's betrayal. They listen to Yuga's desperation that drove him to despair and then Izuku's pleading to let Yuga help them. This leads the class to realize that they can use Yuga to deceive All For One and "steer the villains" in their direction.

Present Mic asks Class 1-A why, with them being the greatest victims after all this, they're so willing to trust him, and 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.

Shota appears on a tablet screen, taking full responsibility and reveals that he has an idea. They all listen to Shota's plan after the Aoyama Family's ears have been covered. Naomasa then has the Aoyama Family escorted back to their HQ, telling everyone not to say a word to anyone else about the plan while he and the rest of the class looking on sullenly.

Back at Heights Alliance, Shoto and his classmates take a breather, before getting ready to gear back up, as he and everyone, with fire and rage in their eyes over the betrayal, prepares to bring All For One down once and for all. After reassuring that Yuga will return and help them, he and 1-A form their "Search Squad" and head out to hunt the villains.

Later that night, Class 1-A ended up with nothing and no information about their whereabouts. After returning to Heights Alliance, Shoto takes a break from his search efforts, feeling incredibly tired. All Might, alongside Naomasa and Nezu, then burst into the dorm, to inform the class 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. 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.

Shortly after the details are planned out and everyone's groups are assigned, Endeavor calls up Shoto, asking him to change, having learned that he will be the one to face Dabi. Shoto responds that Endeavor has to be the one to deal with All For One, since he's the strongest of the Pro Heroes left, same with how Izuku is the only one who can deal with Tomura. Endeavor tries to tell him Dabi shouldn't be his burden to bear, but Shoto insists that it is his decision and he wants to be the one to stop him, as it is his part to play, just as everyone else does to stop the villains for good.

As all the boys head to the baths, Izuku talks to Shoto about his worries for him fighting Dabi, but he says it was his decision, and while his father will be annoyed he couldn't keep his promise, they'll think of it as his "punishment". He tells him Dabi's existence is their family's crimes, and in order to reach what he's aiming for, he can't run from this.

Shoto then shows off the Phosphor technique, which gets Izuku really excited, recognizing it as his own version of Flashfire Fist. The boys mention that he had been focusing on it while Izuku was gone, though Shoto states training and maintaining it is still difficult. He explains that he elevates his Flashfire using his right and left sides at the same time, with his heart being central to make them both manifest, creating what is akin to cold fire through his heated and chilled blood. He mentions how Endeavor wanted to use the ice to control his inner heat, while he's going in the opposite direction. Now feeling more confident in affirming the reason why he was born in his family, he thanks Izuku, saying the words that he told him back 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, with Shoto speaking to Rei, Fuyumi, and Natsuo.

Class 1-A reconvenes at the Makeshift Fortress dubbed, "Troy", a fortified structure where they can stay at. Inside the dorms after moving in, Shoto thanks his friends for being there, thinking about what to do about Toya and how there's so much about him he still doesn't know about, like his favorite food, which Katsuki quips is probably udon, leaving Shoto to respond he wouldn't mind making him sit down to eat with him sometime.

Final War Arc
Shoto stays with Class 1-A at Troy until Izuku is contacted by Yuga and agrees to meet him at a disclosed location, a nearby parking lot. Izuku and Yuga manage to trick All For One, leading him to Warp his remaining villain forces to the location, followed by the Heroes utilizing Warp gate to warp themselves in.

Dabi attempts to incinerate the heroes to hurt his father, but Shoto creates a massive ice wall that matches the power level of Dabi's flames right as he exits the Warp Gate alongside his classmates. He calls his older brother out on being stupid for not counting them in the fight, and the latter responds by yelling his name.

As the battle begins, All Might springs the Troy system trap, catching all of the villains in the cages. Dabi mocks the heroes on how they didn't even last three seconds, but Shoto rebuffs three seconds was all they needed. Using his ice, Shoto shoves in as many villains into the Warp Gates, sucking in everyone in at the same time. There, Shoto enters one of the Warp Gates, and is teleported to Kamino where he prepares to fight his fated duel with his eldest brother.

Dabi proceeds to burn down Kamino Ward with a gigantic fire tornado, dwindling down the accompanying Heroes, and reminiscences on the current events being similar to the Hosu Incident, as seeing that battle was what spurred him to action in the first place. Inside, Dabi is confronted by Shoto, Burnin, Kido, and Onima, lamenting how Endeavor couldn't face him and instead sent his son and his three Sidekicks to deal with him. Onima warns Kido to stay back, since he can't withstand the heat, though Kido notes that he's been redirecting the trajectory of the air around him with his Quirk, and just like he has done for the past decade, he will continue to follow his leader's orders because he wants to. Burnin then says that even despite his family drama, Endeavor always got the job done, and now that he's entrusted them to Shoto, they have his full support, which Shoto appreciates.

Shoto declares that he's not there because someone ordered him, but because he wants to be the one to stop him. Dabi claims that still just makes him their dad's pawn, but Shoto replies that if he simply ignored him and tried to be a hero, then that would be true. Dabi proclaims about how this War is about the people involved, not the mindless soldiers, but the ones who want to change or destroy the world, fighting for their feelings, all representing the limitations of their super-powered society. Shoto then asks Dabi if he was alive this whole time why didn't he come back home, as his increasingly rotting corpse states that, as his older brother, he will explain how he became Dabi, why he's still alive, and how his flames even surpassed his father's "masterpiece".

Dabi then reveals that he survived by being taken in by All For One, only to run away and come home to find his family had moved on and Shoto was now the center of Endeavor's attention. Seeing that nothing had changed, he decided to reject who he was as Toya and became Dabi, now with the sole purpose of destroying Endeavor, studying his hero moves to improve his skill, and keeping himself alive on his pure burning hatred. Shoto realizes through his maddening rants that Dabi has been prepared to die from the start, and with his Quirk going wild, Dabi's body is reduced to a crisped husk before he moves to attack Shoto. Standing defiant, Shoto prepares his Flashfire Fist, declaring he won't succeed.

The increasingly combusting Dabi thanks Shoto for the chat, stating that he'll make for some fine kindling even with their dad not there. Shoto notices how Dabi's raising his temperature even faster than him with no hesitation. Dabi then tells Shoto that he has always thought about him too, before asking if he is a fan of All Might, making a spite of him by unleashing Flashfire Fist: Hell Spider, sending a wide array of fire spirals all outside the tornado.

Burnin, Kido, and Onima protect Shoto as he readies his blast, but Dabi suddenly appears behind him, having used the Hell Spider as a distraction. Dabi throws a fiery punch at Shoto, asking him how he felt holed up at U.A. with all the scared civilians, as the son of Endeavor and brother of Dabi. He continues his assault, lambasting Shoto as despite being "the boy born with everything", blessed with an ideal body in the right place, he still depends on everyone else, and as a half-baked puppet, he'll never make a thing of himself, unleashing a Jet Burn attack that blasts Shoto directly into a building.

However, Shoto manages to neutralize the heat, to Dabi's surprise. He responds that he's not wrong and was full of doubt all this time, recognizing himself as a "half-baked dummy". Despite that, considering he thought Dabi was only ever focused on Endeavor, he was happy to hear that he's been keeping a close eye on him too. Shoto yells to Dabi that even though their dad was a madman and their family screwed up, everybody he burned to death was his own choice, and that he is not taking any more innocent lives. Dabi reacts vigorously as Shoto tells him to aim his rage at his family, unleashing his ultimate Ultimate Move, Flashfire Fist: Phosphor.

With Phosphor keeping Dabi's scorching flames at bay, Shoto regains the upper hand and unleashes an "Icebound Crash - Coldflame's Pale Blade" attack at Dabi, yelling at him to cool his head. Dabi manages to recover using his fire, just as Shoto ends up losing control of his Phosphor due to the lack of extensive training with the technique and needs to switch it back on, just as Dabi pushes his fire into the ground, creating massive volcanic eruptions all over the battlefield, telling Shoto to just burn up and die already.

Fortunately, Burnin, Kido, and Onima take the brunt of the damage to protect Shoto, giving him enough time to recreate Phosphor and go after Dabi. After apologizing, with the Sidekickers telling him not to worry, he yells out thank you, thinking about how after reclaiming so much of himself, it still seemed like everyone else was so far ahead of him. However, they were actually all already beside him, every member of Class 1-A never let anyone behind, and were always there to reassure him.

Building up his fire and ice, Shoto bursts toward Dabi's chest, telling him they're going to mingle whether he likes it or not, and to stop already, blasting Dabi with his Ultimate Move, Great Glacial Aegir, creating a gigantic wave of cold fire that shoots directly through his chest. The fire all over Kamino is frozen over by Shoto's ice, as he grabs ahold of Dabi's body.

With Dabi finally unconscious, the heroes cheer over Shoto's success, ready to deal with the remaining villains and Nomu. The exhausted Shoto holds onto Dabi until a couple heroes arrive to help apprehend him. Ingenium approaches Shoto, who then apologizes for ruining his engines due to his giant attack, but Ingenium tells him there's nothing to apologize for.

However, unbeknownst to him, Dabi managed to copy his Phospor right before he covered him in ice. Shoto then watches in horror as Dabi begins to scorch both Kido and Onima alive, all the while revealing to him how he copied his technique. Due to the fiery battle between the two brothers and the brutal fight between All For One and Endeavor, a massive cumulonimbus storm has started growing all over Japan and continues to expand, combined with a tropical typhoon nearby.

Dabi's inferno continues to endlessly increase and consume the city. Tenya tries to hold Shoto back, telling him his Phosphor move took too much out of him, but Shoto can't believe that despite everyone surpassing their limits to fight, Dabi is the only one still standing. Knowing that his body won't last anymore if he tries to keep fighting Shoto, Dabi decides to abandon his brother, using his feet as jets as he prepares to fly himself directly toward Endeavor at the Gunga Mountain Ruins.

Shoto realizes that he can still move despite reaching his limits, and resolves to go after him. He cries out to his brother, telling him not to run away and calling him the "half-baked one" now, demanding them continue their fight. But suddenly, they are shocked as Dabi is enveloped in a Warp Gate and teleported directly to Endeavor's location.
