Template:Enji Synopsis/Final Act

Dark Hero Arc
In order to track down Tomura, All For One, and the remnants of the League of Villains, Endeavor, Hawks, and Best Jeanist come up with the plan to team up with Deku and All Might, using the former to act as bait to lure out the villains. While Deku looks for more Tartarus escapees, Endeavor goes with Hawks and Best Jeanist to cover more ground and deal with rampant criminals.

While searching for any clues to the whereabouts of All For One or Tomura, Endeavor finds himself under fire by some low-tier villains, with one of them using a very powerful nail gun support item, which he deduces came from Detnerat. He defeats the villain with his Super Move: Ignited Arrow, as they complain that it is his fault they are even out here in the first place. Endeavor, however, says that that is why he is here, and hands him over to the police.

He meets back up with Best Jeanist and Hawks where he confirms the convicts weren't sent by All For One. The three are then confronted by a mob of protestors, calling the three of them 'hero scum' and demanding they get out of their faces. Several of them blame them for the current state society is in for letting Tomura get away and releasing the prisoners. They also reveal they know Tomura is looking for someone else, meaning the heroes are still keeping secrets from them, as well as asking Endeavor if he has seen the grieving relatives of the people Dabi killed on TV.

Endeavor talks with Jeanist and Hawks about the current situation with Deku and All Might, and how he doesn't want Deku to receive more pressure than he already has, admitting how they are using him as bait to lure out the villains even though he asked for it, but are having trouble since they have gone underground.

The Heroes proceed to discuss what the villains' have planned next, assuming the Tartarus escapees had received some orders from All For One, and therefore it is only logical that they are using the greater confusion and chaos to lay low while pursuing One For All. The three deduce that because All Might damaged All For One to the point he needs life-support to live, Endeavor confirms what Izuku said is true: All For One's top priority is controlling Tomura's body, turning Tomura into his successor would make for a new body for him, which is why he is prioritizing this task.

Shortly afterwards, Deku has an encounter with Lady Nagant, who he managed to defeat in battle, though she was soon exploded due to a trap planted within her by All For One. Hawks arrives in time to rescue her, while Endeavor follows behind, having been delayed because of the rain. He apprehends Kai Chisaki who accompanied her, and the heroes prepare to take Lady Nagant and Deku to the hospital to recover.

Before she passed out, Lady Nagant managed to reveal the location of All For One's supposed hideouts in Haibori Woods, so the heroes prepare to head there. Accompanied by The Lurkers, Endeavor arrives with the heroes to infiltrate the base, but finds it empty, only finding a hologram message from All For One sarcastically telling Deku that he took a thorny path of heroism because the more he fights the more his soul will wear down, and reveals that while in prison, he never stopped thinking about him, no longer having any interest in All Might. He gleefully tells him that it is "his turn” as the mansion explodes.

However, the heroes managed to survive, and they reconvene in a warehouse discussing their current fighting strength. Edgeshot brings up the idea of all of them banding together the other heroes and share One For All's secret so they can create a larger network of investigations. Mt. Lady adds that following this incident with Lady Nagant, the brunt of investigating the League is falling all on Deku, and with the police dealing with their own problems and there being zero witnesses regarding the League, they should gather as many allies as they can while they still can.

Endeavor, however, reminds Mt. Lady that Death Arms retired two days ago because despite keeping up the fight, he had gotten nothing but criticism and doubt, and even though there are people who believed in him. Endeavor also adds that the retired heroes are leaking information regarding One For All, and the public are getting close to uncovering the truth about Deku. Endeavor says that if the public finds out about One For All's nature, Deku will be caught in a cycle of negativity.

Mt. Lady says that she wonders why All For One hasn't revealed One For All himself to the public, which Endeavor responds that if he did that, they would do everything they can to keep Deku hidden, so that is the reason why he hasn't done that. However, he admits they don't have any clues unless they and Deku move, and all of them come to face the reality that there aren't enough police forces and heroes to handle it all. Endeavor's phone rings, and he sees a text from Shoto asking him to pick up. He remembers Shoto telling him to let them work together to stop Dabi and he silently apologizes, saying that he needs to wait a while longer.

The heroes then learn from All Might that Deku has abandoned him to go and fight the villains all on his own, leaving them to feel most distraught. However, unbeknownst to him, Shoto and the rest of Class 1-A were getting very impatient with his lack of response, so push forward with a plan to make use of Endeavor's U.A. alumni status to lure him over to the school so they can confront him personally.

Principal Nezu contacts Endeavor, who meets him in his office, but is surprised to see all of Class 1-A present too. Nezu informs Endeavor that he heard what they had to say and decided there was room for discussion since he is constantly getting updates himself. Shoto asks Endeavor why he has been ignoring him and if he forgot the promise they made to stop Toya together. Endeavor responds that it was Shoto's willingness that saved him, but Shoto retorts he doesn't feel the same way without actually doing anything and asks what makes Izuku an exception.

Shoto demands to know if Endeavor is letting Izuku and All Might work together. When he says nothing, Katsuki's suspicions are confirmed, but while he says it may have been the right call, he knows nothing about Izuku. Katsuki states that Izuku has always been crazy for never taking himself into account and insisting he is fine, citing it as the same way All Might became the Symbol of Peace. He tells Endeavor that he can't let the two of them be together, with Endeavor thinking back to when they learned that Izuku had brushed off All Might and how they don't know how else to support him from the sidelines.

Convinced of their resolve, Endeavor decides to hand the students his GPS satellite phone that can pinpoint Izuku's location. Many of them want to help him even though their relationship has been so far school-based and 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.

Endeavor reveals that the outside world is in chaos right now but Nezu reassures them that they are ready. He says that he agreed to let him team up with the top three since he didn't want to return to U.A. and that the villains were targeting him. But he reveals that he can return to school, since the minute they sent out the acceptance notifications, they all became students they will protect. Endeavor asks about the civilians' safety and Nezu tells Endeavor that the designated evacuation areas weren't only chosen based on area, and that the school has reinforced their security "U.A. Barrier" since the Culture Festival. He assures the students that Izuku will be fine if he comes back, so they can go help him.

A few days after Class 1-A confronted Endeavor, he contacts Deku and informs him that the dates for when overseas heroes will arrive will be announced soon, which means they will have more manpower to help with the investigation. He tries to convince Deku to rest, as he knows how much he has been pushing himself, however, he replies that he can still move and he doesn't want to give the villains time to prepare. By then, Deku was already physically and mentally exhausted to the point where he is too weak after being confronted by one of All For One's villains; Dictator until Class 1-A arrived and defeated him.

Despite how exhausted Deku is, he still continues onward to fight against his former classmates while Endeavor arrives near the battle and meets up with Red Riot, Can't Stop Twinkling, and Invisible Girl, who deliver a restrained Dictator to him. Endeavor tells them that Dictator might not be alone and to confirm the safety of the Hero-hating civilians that spread nearby, so they should help Hawks with that. Hawks, however, suggests using Best Jeanist to get it all over with.

As Endeavor sees Deku stuck in Shoto's ice, Red Riot reflects that while there isn't much he can do right now with how much he's moving around, there's still so much he wants to say to him, a sentiment shared by Can't Stop Twinkling and Invisible Girl, who run to check on the civilians. Endeavor tells Hawks that as of now, he shouldn't interfere.

Once Deku collapses from the shock and exhaustion, he returns to the heavily fortified U.A. High where Class 1-A is confronted by angry protesting civilians, who don't want Izuku to be there as they suspect he is the one Tomura is looking for, thus putting everyone in danger.

At that moment, Ochaco takes a megaphone to address everyone. Everyone listens to her speech, appealing to everyone to understand Izuku and let him rest at U.A., reminding them that Izuku has been fighting all by himself for their sake, and now he, as well as the remaining heroes that are still fighting to protect them, needs their support. It works, as the people calm down and allow Izuku to go in.

Outside of U.A., Endeavor, Hawks, and Shoto listen to Ochaco's speech before Ectoplasm lets them in, saying that everything is fine for now. Endeavor was convinced that all they ended up doing was pushing the burden onto Izuku and didn't make any progress, but Hawks says they did take a step forward. Just like how One For All is a power that links together people's hearts, so too is everyone connected here at U.A.: All Might through Izuku, Izuku to his classmates, Ochaco connecting Izuku to everyone, and with everyone thinking about each other, this can lead to the bright future where everyone will have time to laugh.

As Class 1-A helps with the civilians and Izuku is escorted inside, Shoto turns to his father and tells him they're doing it together, thinking back to Toya's face, which he agrees. The next day, while Izuku rests, Endeavor flies to a specific location, being followed by Hawks and Best Jeanist in the latter's car.

Based on the information obtained from Doctor Garaki's interrogations, the confessions of the captured agents, and the research of the Nomus in Central Hospital, they believed that they still have at least a month to make their move to take down All For One, however, new information has changed things.

Star and Stripe Arc
Thanks to information given to All Might by Stain, which he received from Tartarus, the heroes learn that Tomura will be completed far sooner than they initially believed. Due to this, All Might puts in a request for immediate aid from the foreign heroes, which is responded by America's No. 1 Hero, Star and Stripe. Endeavor, Hawks, and Best Jeanist head out to rendezvous with her, when they suddenly hear a warning call from Naomasa that "Tomura" has shown himself and confronted Star and Stripe.

The three rush their way toward their location, with Endeavor spotting the two's devastating battle from afar, however reach the location too late, with Star and Stripe being killed and Tomura escaping, but not before she used her Quirk, New Order, to deal heavy damage to "Tomura", destroying several of his Quirks and forcing him to flee. The heroes try to track down "Tomura", but he is able to go back into hiding.

With the death of Star and Stripe, the rest of the nations prefer not to send help to Japan to keep their homelands protected. The only positive thing about the battle is that, thanks to the data and records obtained by the pilots about "Tomura", he ended up so badly injured that he will need another week to recover and complete his body.

U.A. Traitor Arc
During the week, Yuga Aoyama is discovered to be a spy for All For One, being captured along with his parents by Izuku. When questioning them, it is discovered that they are only agents of All For One because of the fear that he instilled in them after he gave Yuga his Quirk. Despite this, the heroes devise a plan to use Yuga and his parents against All For One, in order to ambush him and separate him all the villains so they are unable to help each other.

Endeavor continues to assist the remaining available heroes in taking down any of the escaped convicts they come across, while Hawks meets up with All Might and the newly formed "Counter-Force" to come up with a plan to take down the League of Villains for good. He and Ragdoll later proceed to inform all the heroes of the details behind the plan, approaching in just a few days.

Learning that the plan is to pit Shoto and Dabi against each other, Endeavor calls Shoto asking to reconsider the team placement, believing he should be the one to deal with Toya. However, Shoto responds by mentioning All For One, since among the remaining Heroes, he's the only one with a chance to stand against him, just like Izuku is the only one who can face Tomura. He says that not only is he the best pick to stop Toya, he wants to be the one to do it. Endeavor says it should be his duty, but Shoto responds everyone has their part to play, and together they'll defeat all the Villains.

Final War Arc
The plan is revealed to be to utilize Yuga and Izuku to lure All For One and his forces out of hiding into an abandoned city outside, using Hitoshi Shinso's Quirk to deceive All For One. Thinking that he has already succeeded, All For One is caught off guard when the farce is revealed, so uses his Warping Quirk to bring his remaining forces to the area, only to be further surprised when dozens of heroes begin to appear through several Warp Gates, created by Neito Monoma, who had copied Kurogiri's Quirk.

As the Heroes and Villains charge toward each other, Dabi taunts Endeavor, preparing to burn everyone with his fire, but from another portal the U.A. students emerge, with Shoto canceling his brother's fire with his ice. Then, All Might and Naomasa activate the "Troy" system, causing numerous cages to rise up from beneath the battlefield to encapsulate and separate the various villains parties, holding them long enough for Neito to summon several more Warp Gates around the cages, and allowing the heroes to shove them all in, splitting up the villains into different parts of the country, separated from each other by hundreds of kilometres.

Endeavor leads the charge against All For One, warping them all to the ruins of the Gunga Mountain Villa, where Hawks is waiting, attempting to strike All For One straight in the head with his Quirk, but failing to get through his mask. Hawks apologizes to Endeavor for it, but the flaming hero tells him to relax, since he did not have much hope that such attack would work.

Endeavor taunts All For One, stating that they knew his own Warping Quirk was inferior to Kurogiri's Warp Gate, having a much lower range and unable to warp himself either. For this reason, the U.A. Barrier got some upgrades taking these drawbacks in mind, and that his hubris will now lead to his downfall.

All For One mocks the heroes' plan to split them up, pointing out that dividing their forces due to the decline in heroes was necessary, while also noting the supposed ill-fated decision to pit "One For All" against Tomura, and worst of all to have Shoto face off against Dabi, with All For One criticizing Endeavor for having his youngest son clean up his mess, and continuing the abuse toward the oldest.

Endeavor and Hawks choose to face All For One in the air, keeping the other heroes out of harms way to avoid getting their Quirks stolen, with the goal of destroying his mask, which they know he uses as his life support. While they are in the middle of their fight, Endeavor hears the news that Shoto has defeated Dabi, unsure how to feel. Seeing his expression, All For One taunts the hero, berating him for not even looking at Toya and letting Shoto handle everything, confidently stating that is why he'll never win, as he prepares to attack with his arsenal of Quirks.

With the tide of the fight being turned, Endeavor and Hawks charge at All For One. The villain shoots several Razor Blades at them, but Endeavor blocks it with a Hell's Curtain, while Hawks shoots his Fierce Wings through it, which All For One dodges. Endeavor plunges into All For One with a Vanishing Fist, with All For One attempting to block with his Hardflame Fan, but the heat starts to pass through, and he's unable to reflect it with Impact Recoil. Seeing Hawks ready to counterattack, he asks if they're having trouble coordinating, and if Endeavor's heart isn't in it. Endeavor brushes this off, saying that they've been landing damage on him, with him not having anything like Hyper Regeneration.

All For One continues to taunt Endeavor, showing him all the Pro Heroes and students fighting on the ground, focused on their battle, while he's got his mind focused on other things, asking if he's thinking about how his "masterpiece" took care of his "failed experiment". Hawks tries to tell Endeavor not to listen, reminding him what happened to All Might in Kamino, but Endeavor can't resist. All For One sticks the knife in further, commenting on how he's always been interested with Endeavor's twisted longing for power, and after saying he can't help but sow seeds he comes across, comments on him never finding Toya's body, revealing his role in his disappearance. The revelation shakes Endeavor to the core, realizing that All For One was responsible for his son's downfall.

Full of anger and rage over All For One's manipulation and the corruption of his son, Endeavor screams out to the villain and attacks him blindly, allowing All For One to catch him off guard and slice his chest with a Quirk combination attack. After landing on the ground, Endeavor thinks about both of his sons, and wonders if they are both okay. He then laments over how foolish it was to let All For One get him, and that everything he's had to deal with is all on him.

As he's recovering, Earphone Jack and Tsukuyomi join the battle and help Hawks in destroying All For One's life support mask. However, in a fit of rage, All For One unleashes a hell of Rivet Stabs, both to repair his mask, and to skewer the three Heroes. Endeavor returns to the battle just in time to protect the three from most of the damage, losing his right arm after one of the Rivets gets into contact with him. As All For One continues to mock him, within his mind, his younger self berates him for his weakness and tells him to remember his origins. He then continues to tell him that he will never be like All Might nor Deku, and that he's been fighting his weakness this whole time. Back in the present, Endeavor creates a fiery fist in place of the arm he lost and then blasts All For One, declaring to him that ending this battle once and for all is his duty.

All For One barely manages to protect himself from Endeavor's fiery assault, but the Hero doesn't let up, charging up his flame fist, and thanks to a boost from Hawks' feathers, catches All For One off guard to unleash a Vanishing Jet Burn, shooting him down to the Gunga Mountain. Hawks asks Endeavor why he didn't finish him off with Prominence Burn, but Endeavor remarks that he had his guard up, and since he can't use it as many times as he wants, he needs to break through his defenses to ensure it connects.

Endeavor blasts himself downward after All For One, causing all the remaining Heroes to flee and get out of the way of their incoming rampage, grabbing the villain and dragging him all throughout the forest. All For One attempts to grab Endeavor and steal his Quirk, but he proceeds to shoot fire from his eyes, burning his hand. Endeavor states that all his hands do is ruin people's futures, to which All For One claims he does too, with Endeavor agreeing.

He thinks about how Toya is the result of his mistakes and led to many stolen futures and declares that since the future is the path for the youth, he will win this so that the past won't get in the way of their future. Endeavor says he will keep paying his penance so he can keep looking after Toya, all the while his rage will continue to burn, blasting All For One with a Prominence Burn. Holding his crisped remains, he thinks about how they already confirmed he doesn't have any Hyper Regeneration, but even if he did, there's no surviving that attack without a body like Tomura's. But then, Hawks cries out to Endeavor to get away.

Somehow, All For One begins to speak, asking if he believed he would show up to the big battle empty-handed. As an eye and an ear emerge from his body, with a grinning smile, All For One asks what made him think Heroes were the only ones to make "sacrificial moments", and that Villains are also scariest when wounded.

Much to his and Hawks' horror, All For One has resorted to using a reversed-engineered Quirk-Destroying Drug on himself, which used the original function of the Rewind Quirk to rejuvenate his body back to its prime. Endeavor and Hawks are stunned as they see an almost fully recovered All For One declaring that while the Heroes managed to keep the Villains on the defensive in the previous battle, it won't be the same now; since Heroes are those who will defend, Villains are those who will violate, and they will plunge headlong to their dream.

All For One praises Endeavor for making him use the last trump card he's got in his arsenal. Endeavor is mortified that All For One is regenerating himself back to his physical prime, while he struggles to recover. All For One swiftly makes his way down to the battlefield, with Hawks giving chase to confront him.

Hawks attempts to buy time by telling All For One to explain his ideals, where he proceeds to declare that people's experiences when they're young define who they become, referring to Spinner's dark upbringing, so his feelings for the friends who accepted him are strong. He also mentions he installed a microchip in Nana Shimura's hand to make sure Kurogiri is active no matter what state he was in.

He yells that Spinner has succeeded as above the Heroes he notices two Warp Gates appearing. Dabi gleefully and maniacally emerges from one of them, saying hi to his dad, while Endeavor watched him, stunned by his reappearance. Accompanying him is Himiko having transformed into Twice, and immediately begins unleashing a Sad Man's Parade on the Gunga Mountain.

While fighting off Twice Doubles, Endeavor recognizes the fire around Dabi's chest as Shoto's Phosphor move, asking what happened to him. Dabi says he wanted to give him his head but he was too strong, upset that his dream won't come true, but he will still try to take as much as he can from whatever he tries to protect. While Hawks is fighting All For One preventing him from escaping, he yells out to Endeavor that since their divide and conquer plan was a bust, if things fall apart now it will eventually reach Deku and Tomura, so they need to stop Dabi now.

All For One attempts to lambast Hawks by reminding him that Endeavor's already lost an arm and that he's supposed to be trying to stop him rather than abandoning his duty, but Hawks smugly responds that he's already lost to him once. As Dabi comes charging toward him, Endeavor thinks about his duty, and how this time, he's really seeing Toya.

Knowing that Dabi still posed a big threat to the heroes despite the villain burning himself to a crisp, Endeavor jets himself into the forest far away to let his maniacal son to jet himself after him, unaware that the Shiketsu High School Hero Course students have joined the war. Inasa Yoarashi uses his Whirlwind to suck up all the Twice Doubles and Himiko into the air, giving the Heroes the opportunity to counter attack. With additional reinforcements from Shiketsu High, the battle in the Gunga Mountains have has become the turning point as the Heroes are now at the offensive, While Inasa continues to suck up all the Twice Doubles along with Himiko among them, Kamui and the Heroes that have long-range attacks pour in everything they’ve got at All For One.
