Story Impact

 * All Might, Naomasa Tsukauchi, and Nezu inform Class 1-A of their plans for the "Final War".
 * Using Hitoshi Shinso's Brainwashing Quirk, which he has trained to allow him to get people to speak, he can brainwash the Aoyama Family so they can communicate with All For One without him detecting any lies in their voices, and allow them to lure him to a specific location.
 * Meanwhile, Shota Aizawa enlists Neito Monoma to Copy Kurogiri's Warp Gate Quirk, so that the Heroes can be warped onto the battlefield for a surprise.
 * It is revealed during the first era of Quirks, All For One stole a "Lie Detector" Quirk from one of Naomasa Tsukauchi's ancestors.
 * He commands the Aoyamas to deliver Izuku to him, using the Quirk to determine they aren't lying.
 * After meeting in an abandoned parking lot, Yuga seemingly betrays Izuku to All For One, only to reveal it was all an act they put on to lure him out of hiding.
 * He also reveals during the charade All For One's ultimate goal to instill chaos throughout the world so that Quirks are the only thing of value, so that he may rise up with his arsenal of Quirks and take control of everything.
 * All For One warps all the Villains to fight, while the Heroes, thanks to Neito, utilize the Warp Gate Quirk to warp themselves to the battlefield.
 * As the final battle between the Heroes and Villains begins, All Might activates the "Troy" defense system, surrounding all the villains into separate cages, delaying them enough for the Heroes to throw them into separate Warp Gates, splitting them all up.
 * All For One is warped to the ruins of the Gunga Mountain Villa, to face against a group of Heroes led by Endeavor and Hawks.
 * The team also consists of Kamui Woods, Shishido, Pixie-Bob, Tiger, Shemage, Tsukuyomi, and Earphone Jack.
 * Dabi is warped to Kamino to face off against Shoto.
 * The team also consists of Burnin, Kido, Onima, and Ingenium.
 * Tomura Shigaraki is warped to a now floating U.A. High, with the intention to face against Deku, but he's instead snagged away and ends up in a separate Gate.
 * The team also consists of Dynamight, Best Jeanist, Edgeshot, Mirko, Nejire Chan and Suneater.
 * Himiko Toga is warped to an aquarium on Okuto Island to face off against Uravity, Froppy, and Deku, who she had forcefully dragged with her..
 * The team also consists of Gang Orca, his Sidekicks, and Sirius.
 * Fat Gum is in command of the parking lot, to watch over Yuga and deal with the villains who weren't warped.
 * It is revealed the floating U.A. Fortress is designed to break off into individual segments in order to counter Tomura's Decay, as well as being surrounded by an electromagnetic barrier to prevent him from escaping.
 * The fortress is maintained by Power Loader, Cementoss, Mei Hatsume, and the Development Course to rebuild the broken pieces, with Mei being the one who designed the original structure.
 * Additional resources are provided by Creati, while the power to sustain the energy and barrier is provided by Chargebolt, Comicman, and the other electricity-based U.A. students.
 * Furthermore, Phantom Thief, assisted by Eraser Head and Manual, copies Erasure to once again erase Tomura's Quirks.
 * "Tomura" suddenly begins to sprout a monstrous glob of never-ending fingers from his left hand, revealed to be a result of the Quirk Singularity, with his body adapting to the immense amount of power he possesses.
 * Deku is unable to be warped to their location, due to Phantom Thief only being able to use one Quirk at a time, and the danger of undoing Erasure on "Tomura", forcing the Heroes to fight him in the meantime.
 * On Okuto Island, Himiko attacks Deku, bypassing his Danger Sense due to not having any malicious intent, asking him to be her boyfriend.
 * Deku's response causes Himiko to feel rejected, as Uravity and Froppy resolve to handle her, while he blasts away across the ocean back toward the battlefield (using Float, Fa Jin, and Air Force).
 * The Second User of One For All cautions him not to overdo himself, as well as revealing that his Meta Ability has evolved beyond the point it used to be, and so must only be used as a last resort.

 * It is revealed that Toya survived his "death" after being rescued by All For One and Doctor Kyudai Garaki, intending to raise him as one of their "spare vessels".
 * He was comatose after his accident and awakens after three years, where he learns the experimentation process failed, with Toya still unable to handle his fire with his new body.
 * Toya escaped the nursery, with All For One and the Doctor letting him free, being unable to manipulate through his obsession with Endeavor, and believing he will only last a month till he dies.
 * Toya secretly returned home to find Endeavor continuing his abuse to Shoto, and once again reminded of his status as a failure, left his Toya identity behind and was reborn as "Dabi".
 * After being reunited with the Doctor years later, he realizes Dabi managed to survive all this time purely on his grudge toward his father.
 * Having studied his father's moves to get stronger, and breaking off his limits with his new body that can't feel pain, the increasingly combusting Dabi utilizes the Flashfire Fist technique to unleash attacks on Shoto and the Heroes.
 * Shoto unveils his own Flashfire Fist technique, Phosphor, a move completely of his own making, combining his fire and ice into one, which he declares he'll use to take Dabi down.
 * He's eventually able to use this technique to power his Ultimate Moves, neutralizing Dabi's fire and seemingly defeating him.
 * All Might announces to all the battlefields of Shoto's success against Dabi, boosting everyone's morale.

 * At the Gunga Mountain Ruins, All For One faces off against Endeavor and Hawks, who fight him alone in order to keep him away from the other fighters while trying to remove his new life support helmet.
 * It is revealed not all of Hawks' feathers were able to be recovered, so he wears prosthetic ones to reclaim some of his speed.
 * All For One taunts Endeavor, revealing his role in Toya's disappearance, allowing him to catch him off guard and slice his chest.
 * Tsukuyomi and Earphone Jack manage to save Hawks from All For One's attack, ready to help him fight and buy time till Endeavor recovers.
 * Earphone Jack loses her left ear and subsequent earphone jack from an attack by All For One, but continues to fight back and resist despite his taunting and mockery.
 * The vestiges of the Quirks All For One has stolen in the past start to resist against him, due to him possessing a copy of All For One, making him weaker and more vulnerable.
 * The three remaining fighters successfully manage to destroy the mask, but All For One regains control of his Quirks by absorbing several of them into himself, and unleashing a hell of Rivet Stabs to attack his opponents and reclaim the pieces of his mask.
 * Endeavor returns to the fight to protect the three Heroes from most of the damage, but losing an arm in the process.
 * It is revealed what inspired Endeavor to be a hero was after seeing his father get killed while trying to save a girl from a villain.
 * Endeavor conflicts with his younger self about his actions and desires, declaring to makeup for his mistakes, he will put an end to All For One so the youth will have a better future.

 * The fight against Tomura at the U.A. Flying Fortress continues, as the Heroes try to avoid the fingers and reach the main body.
 * Dynamight attempts to unleash the full power of his Cluster attack, only to be stopped by Tomura, crushing his right arm, telling him he's only interested in him due to his closeness with Izuku, intending to kill him to enrage Izuku like what happened during the War.
 * Lemillion arrives on the battlefield, revealing that he was also within the U.A. Flying Fortress, in charge of communications and acting as a bodyguard, and reunites with The Big 3 to fight Tomura.
 * Lemillion rescues Dynamight, telling "Tomura" he doesn't have any friends as he attacks him.
 * This unintentionally causes the spirit of "Tenko Shimura" that remains within him to re-awaken, leading "Tomura" to realize their melding is still incomplete.
 * Details about Nejire's past are revealed.
 * She used to be cold and distant towards everyone at U.A., due to their belief that she looked down on them because of her powerful Quirk, until Tamaki, and then Mirio, befriended her, causing her to open up.
 * Tamaki unleashes the true potential of his Quirk, the Vast Hybrid: Plasma Cannon, creating an ultimate fusion of every animal and plant he has eaten in his system, combined with Nejire's energy, to attack "Tomura", but unfortunately isn't enough.
 * Despite the pain and humiliation in his body, Dynamight tries to face off against "Tomura", outspeeding his movements.

 * He learns thanks to Skeptic Endeavor's location at the Gunga Mountain Ruins.
 * Skeptic is revealed to have re-taken control of the Feel Good Inc. satellites, preparing to hack into the U.A. underground bunker.
 * Among those in the underground bunker are Eri, the Todoroki Family, and the Masegaki Primary School staff and students.
 * It is revealed the Doctor reverse engineered the Quirk-Destroying Drug and created a sample that executed the original Rewind effect on the entire body.
 * He left it, a new mask, and a pre-recorded message for All For One to find in the secret underground cave as a contingency measure, warning it can only be used as a last resort, as it will eventually rewind him to nothing.
 * All For One uses the drug to regenerate himself to his prime state, for the limited time available, to rescue Tomura from the Heroes' trap.
 * All For One's face is shown un-silhouetted for the first time.
 * In America, Timothy Agpar attempts to reason with the President to target Tomura, who instead suggests appealing to him, believing him to be unstoppable.
 * Edgeshot uses his Quirk to enter Dynamight's body, becoming as thin as a surgical suture to repair his heart, even at the cost of his own life.
 * It is revealed that Best Jeanist and Edgeshot went to U.A. together and created the "Textile Arts Association", with Best Jeanist as the club president.
 * Tomura, in a fit of rage, tries to stop the Heroes from their recovery attempt, but is held back by Mirko and the others.
 * Tomura realizes that he feels threatened by Dynamight, unable to understand why.
 * Mirko loses her right arm, being chomped off by Tomura's finger wave, but continues to fight, using her Ultimate Move Luna Rush to knock Tomura down.
 * Within Tomura, Tenko starts to get corrupted as the memories of not being saved by anyone flood back to him.
 * As a result, he begins to transform into a defensive state where his fingers surround his entire body, while the visages of the Shimura Family are emerged from his left hand.
 * Tomura uses this power to completely decimate the remaining Heroes, leaving Lemillion unable to do anything to stop him.
 * The Heroes receive word from Mandalay to delay Tomura for two seconds so they can remove the electromagnetic barrier.
 * Remembering Sir Nighteye's words, Lemillion moons Tomura, distracting him for long enough.
 * Deku finally arrives on the battlefield, using Blackwhip to slingshot into Tomura, joining the fight.
 * He goes into a state of shock upon seeing Dynamight and all the other Heroes' comatose bodies, causing his emotions and Quirks to erupt out of control, which "Tomura" attempts to take advantage of to attack him.
 * Lemillion is able to calm Deku down by telling him everyone is still alive and get him back to his senses.
 * Deku confronts "All For One", asking if Tomura is still in there.
 * He claims that the original Tomura is no more, now that he and All For One have merged into a new being, with All For One mainly in control, but Lemillion reveals "Tomura's" unstableness, realizing they aren't truly fully merged.
 * Nana Shimura sees the visage of her son Kotaro on "Tomura's" body, also coming to this conclusion.
 * Deku uses the Second User's Quirk, Gearshift, to power two new Ultimate Moves. The first being Transmission, shifting the speed of anything he touches through different gears. The second is Overdrive, activating the Second User's Quirk on himself and giving a power-up to his existing Ultimate Moves.
 * Deku uses Overdrive to greatly enhance his speed, boosting his power to 120%, greatly overwhelming "Tomura".
 * It is revealed that in the past, the Second User's Meta Ability was only powerful enough to control the trajectory of small objects.
 * We see the conclusion of his battle with All For One, where the villain is shown crying.
 * Deku utilizes the power of all the Quirks of One For All together to overwhelm "Tomura", and execute his ultimate attacks.

 * She also faced predjudice due to her looks, but was defended by his father, telling her son to follow in his footsteps and get mad at people who laugh at those he loves.
 * Anima undergoes his transformation, using his newfound growth in abilities to defend Tentacole by attacking the Liberation warrior.
 * Tentacole also transforms himself to keep up with Spinner, pleading to him and the crowd not to misplace their anger and resentment.
 * Spinner repeats his "call to action" and not to waver, charging his way toward the Hospital at blistering speeds.
 * He breaks into Central Hospital, barreling towards Kurogiri's location, with the intention of using All For One or Tomura's voice to awaken him.
