Template:Tenya Synopsis/Final Act

Dark Hero Arc
Tenya is confused along with the rest of the class of what happened between Izuku and the truth of One For All. A few days after he left U.A., Tenya holds a meeting with Class 1-A and asks Katsuki, Shoto, and Fumikage if they can confirm their suspicions by contacting their respective mentors, but all three of them report that they refuse to respond, believing they are hiding something from them. Class 1-A deduce that Izuku and All Might are now working with the top three heroes, but need to find some way to confirm their suspicions.

Ochaco suggests taking advantage of Endeavor's U.A. alumni status to confront him, which is backed up by Nezu. After learning the truth from him, Endeavor is convinced of Class 1-A's dedication to Izuku and Tenya declares that as Class 1-A, they will follow Izuku wherever he goes, and no matter how much responsibility that comes with One For All, they consider him their friend, and they won't let him walk such a troublesome path all by himself.

Nezu gives permission to allow the class to bring Izuku back home to safety, and Tenya leads Class 1-A to search for him across the country while apprehending any escapees from Tartarus and the other prisons. After a month since he first left, Tenya and Class 1-A arrived on the scene to defeat Dictator during his battle with Izuku. Izuku asks why they are all here and insists that he is okay and that they shouldn't worry about him and leave, but they all refuse to leave him. When Izuku refuses to yield, he demands everyone to get out of his way, which means they might have to fight Izuku, with Tenya telling everyone else to stand strong.

Class 1-A proceed to duel with Izuku as he attempts to escape them, while they try to restrain him so they can return him back to U.A. During this, Tenya thinks about how once Izuku sets his mind on something, he never stops. Eventually, Izuku finally tries to escape into the sky, so Class 1-A brings out their ultimate plan. Tenya is coated in Mina's Acidman, with the heavy-hitters, including Mezo, Rikido, Koji, and Fumikage, pushing him and Katsuki forward as Shoto blasts the two up the ice ramp with his Flashfreeze Heatwave. Ochaco tags Katsuki and the Acidman with her Quirk, and then Katsuki blasts Tenya even further into the air at blinding speeds using his Blasting Speed Turbo: Cluster as the Acidman melts away.

With sheer speed, Tenya successfully grabs ahold of Izuku's hand, completely shocking him, still insisting for him to let go. Tenya refuses, stating that he is a hero who will always take a lost child by the hand, and repeating Izuku's words when he saved him from Stain that "giving help that's not asked for is what makes a true hero."

Ochaco releases her Zero Gravity, causing Tenya and Izuku to fall toward the city. He wonders how he's going to stick the landing, when he sees Eijiro who manages to catch the both of them. Tenya and the rest of Class 1-A listen to Katsuki apologizing to Izuku before he finally collapses from the shock and exhaustion. Once Izuku is secured, they escort him safely back to a heavily fortified U.A High where they are confronted by protesting civilians.

The civilians are distressed because they are aware that Tomura is targeting Izuku and him being there at U.A. will put them in danger too. Everyone tries to reassure them but to no avail, until Ochaco floats her way up to the top of the building, shouting down to everyone and giving an impassioned speech to let Izuku stay. During the speech, Tenya and the class watch on in awe, with him telling Izuku that she is fighting for him and everyone's right to smile again, as he eventually tears up and breaks down in exhaustion.

Kota Izumi and a mutant woman rush up to comfort him, with Tenya holding Minoru back from doing so, telling him it's not their turn yet. With all this, the civilians agree to let Izuku stay, and Tenya and the rest of the class proceed to escort him inside. The boys immediately rush Izuku to the bath, stripping and washing him down before getting in themselves. Afterwards, Class 1-A is visited by All Might, where he and Izuku apologize and make up before he heads back out. With Izuku finally passing out and getting some rest, 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 in the courtyard, where they discuss about their plans for the incoming conflict. Izuku says how they need to try and dictate how they enter the fight, and that he's going tor rejoin the search soon, before being reprimanded by Tenya, reminding him that "we" will be rejoining the search. Izuku then 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.

Shortly after this, Tenya and the rest of the class receive the devastating news that Izuku had just captured the Aoyama Family, learning that they have been spies for All For One, and Yuga was the traitor who isolated the class at the U.S.J. and revealed the location of their training camp. Restraining them in the AV room, he and the other class members refuse to back down from the news despite Nezu's request, all in stunned and tears of Yuga's betrayal. He listens to Yuga's desperation that drove him to despair, followed by Izuku's pleading to let Yuga still help them.

The rest of the class quickly realize that they could have Yuga help deceive All For One and "steer the villains" into the fight, and when questioned why they're so willing to trust him, 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 then appears on a tablet screen, taking full responsibility and reveals that he has an idea, which Class 1-A, the U.A. Staff, and Police Force hear while 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 look 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, prepare to bring All For One down once and for all. Tenya and Izuku head to the Development Studio in order to fix up their hero costumes, when Izuku is suddenly caught in a very familiar explosion blast, which Tenya sees as "deja vu", soon spotting Mei Hatsume emerging from the smoke, landing directly on top of Izuku.

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. Mei is confused why they don't just take them to the item agency, and Tenya responds that with recent disruption to the agencies, they have to rely on the support course. 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, due to how damaged it is and not having the available materials. Tenya then asks for repairs for his armor, but just as quickly she shuts him down due to not having a spec sheet. Two of her classmates approach the two saying they'll make it for them.

Tenya is surprised that Mei would turn down the offer due to how much she loves making things, as they look 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.

After Mei tells Izuku about how even she is aware of the trouble Heroes are facing now, and that inventing stuff is how the support course does heroics, she suddenly 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. 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. Following Izuku, the Class 1-A Search Squad assembles and heads out.

Later that night, Class 1-A returns to Heights Alliance, unable to find any information about the villains' whereabouts, to take a break from their search efforts, feeling incredibly tired. Tenya advises everyone to get some rest as soon as possible, when All Might, Naomasa, and Nezu arrive into the droms, informing them all about their secret finalized plans for the upcoming Second War.

The next day, Nezu announces to the civilians that Tomura will make his big move in 4 days, with Class 1-A moving outside of the U.A. barrier to begin prioritizing their safety. Tenya says goodbye to his family members one last time before heading out. The class proceeds to move into the upgraded makeshift fortress called "Troy". After unpacking, Tenya, Katsuki, and Eijiro go to visit Shoto to comfort him regarding Dabi, with Tenya offering his support as someone who also has an older brother.

Final War Arc
The plan is revealed to be, utilizing Hitoshi Shinso's Brainwashing, they will brainwash Yuga and his parents when they contact All For One, allowing them to deceive him without him being able to detect any malicious intent, luring him to a specific area. Then, using Neito Monoma copying Kurogiri's Warp Gate, they will summon several portals which will not only warp the Heroes to the battlefield to surprise the villains, but also to create portals which they will use to send the major threats all over Japan and split them up.

On the day of the operation, All For One and the villains are successfully drawn out by Izuku and Yuga, with the Heroes and then Class 1-A themselves warped to the battlefield soon after. Before the fighting can truly start, the "Troy" defense system is activated, trapping many villains in cages from beneath the battlefield.

The villains are able to quickly escape, but were delayed long enough for the Heroes to push the villains into their respective portals. Tenya joins the team consisting of Shoto, the Flaming Sidekickers, and several other Heroes, to end up in Kamino to face against Dabi.

Dabi proceeds to completely burn everyone down in a fire tornado, accompanied by a Near High-End Nomu, which dwindles down the accompanying Heroes. Tenya, meanwhile, is forced to stand outside the fire tornado, noting the incredible heat and how he can't get any closer or his Engine will overheat, while Dabi is confronted by Shoto, Burnin, Kido, and Onima.

Tenya continues to evade throughout the battle as Dabi unleashes his Flashfire Fist: Hell Spider to send a wide array of fire spirals all outside the tornado. The Heroes try to avoid it, recognizing it as Endeavor's move, with Tenya noticing it as thicker and more haphazard, causing him to worry about Shoto. Nonetheless, Shoto is able to overcome Dabi's burning hot blue flames and defeats him with Great Glacial Aegir Ultimate Move.

With Dabi defeated, the Heroes cheer over Shoto's success, having taken care of all the accompanying villains, and resolve to finish off the last threat in the vicinity, being the Near High-End Nomu. Tenya goes to help Shoto while several other Heroes deal with Dabi. Shoto apologizes for messing up Tenya's Engines with his attack, with him telling his classmate he has nothing to apologize for.

However, unbeknownst to him, Dabi managed to copy Shoto's Phosphor right before he covered him in ice. Tenya and Shoto then watch in horror as Dabi begins to scorch both Kido and Onima alive, all the while revealing to him how he copied his technique.

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. Dabi then prepares to fly himself directly toward Endeavor's location, when he's suddenly enveloped in a Warp Gate and teleported there. Despite Dabi's disappearance and the inferno still around them, Shoto declares it is not over yet, supported by Tenya, both unaware that Stain is observing their determination from afar.

Because of how much Phosphor took a toll on his body, Tenya tells Shoto he hasn't recovered from using it yet, but he insists he's fine, yelling that All For One is about to reach Izuku and he can still fight. Tenya continues to speak about how he can only imagine the thoughts in his head having to fight his brother, wondering why this must be his emotional burden to bear, especially after all he has done and shown to him.

Just then, the two receive a call in their communicators from All Might, telling them to run to Gunga as he informs them of even worse news. They learn that ever since Shoto defeated Dabi, he has been internally compressing thermal energy inside of his body, and continues to compress even more. With all of his Blueflames building up, in about ten minutes, his body will explode and cremate everything within 5 kilometers in a massive nuclear blast. In addition, several of the U.A. evacuation blocks are trapped directly within the blast radius.

All Might warns them about all this, telling Tenya to he knows he can handle running there, and telling Shoto that he knows his mind and body are one. After saying that a "powerful ally" is waiting to deal with All For One, All Might continues telling the two that he has the utmost respect to those who still continue to fight even with doubts, telling them to stop Dabi and reassure everyone, and that they need the two of them and their Quirks together to avert the disaster.

Initially, Shoto is worried that Tenya's unable to run all the way to Gunga since his Engine was stalled, but he simply responds that the rain cooled his Engines off, reminding Shoto his legs exist to guide wayward children. Tenya puts his mask and armor on Shoto as he blasts off at his maximum speed while carrying Shoto across the city to reach the location.

On their way to the battlefield, Shoto and Tenya create a jet made of ice to help themselves in reaching their destination fast.
