Template:AFO Synopsis/UA Beginnings

U.S.J. Arc
All For One's first command for Yuga was to discover and report when the class and All Might would be isolated together. Thanks to a distraction caused by Tomura, he informed him that All Might would be teaching them while at the Unforeseen Simulation Joint, leading All For One and Kyudai to supply Tomura and Kurogiri with an army of no-name thugs to act as their "League of Villains", but also their perfected Nomu, designed to kill All Might once and for all.

Unfortunately, their plan fails, and Kurogiri is forced to warp himself and an injured Tomura back to their hideout at the last second, allowing them to escape from being defeated. Tomura berates over his failure, his injuries, losing all their subordinates, his Nomu being defeated, and All Might surviving. However, All For One, speaking on the monitor, says that nothing went wrong and that he was simply over optimistic. Tomura mentions one kid in particular who kept getting in his way, and had a power similar to All Might's, which interests All For One.

He says that it is too late to mourn and that they should gather a new group hand picked for efficiency, saying that they should take all the time they need. All For One tells Tomura that he's a symbol of importance and that next time he will show the world the horror of his existence.

U.A. Sports Festival Arc
A recuperating Tomura watches the U.A. Sports Festival, including the Obstacle Race where he sees Izuku take first place. Later on, before the battle between Izuku and Shoto Todoroki begins, All For One tells Tomura to pay close attention to their match as they might become obstacles for him in the future. Tomura responds by telling his master to not make him laugh.

Vs. Hero Killer Arc
All For One, using his monitor to speak through, orders Kurogiri to allow Stain and Tomura to continue talking, saying that Tomura's meeting with Stain, an experienced infamous villain, will stimulate Tomura's growth. Before he leaves for Hosu, Tomura asks All For One to let him borrow some Nomu because he does not like the "Hero Killer" Stain and that destroying things he does not like seems alright. All For One decides to give Tomura three Nomu, hoping that Tomura will make the opportunity a learning experience.

In the aftermath of the incident, two of the Nomu are killed, one is detained, and Stain is captured. The latter surprises All For One, but he is still happy that things are going as he has foreseen. He exclaims that Tomura's position is to supervise and unify the new villains who have come to join the League of Villains. Doctor Garaki expresses doubt that Tomura can do his job and says that if All For One stepped in things would be proceeding faster. All For One proceeds to ask the Doctor to patch him up faster, adding that he will let Tomura do all the hard work so that he may become his successor as Tomura was born to do so. All For One tells All Might to rejoice in the "transient" peace while he still can.

My Hero Academia: Two Heroes
Learning about David Shield's plan to break into I-Island during its Expo, All For One contacted Wolfram, the Villain hired to assist in the scheme, and provided him with an additional Muscle Augmentation Quirk, wanting to have a hand in All Might's former partner's fall to villainy.

Forest Training Camp Arc
Thanks to an interaction between Izuku and Tomura, U.A. decided to change at the last minute the location of the upcoming Quirk Training Camp, to keep it a secret from potential villain attacks. Despite this, All For One was able to figure it out by commanding Yuga to reveal the location, the information he promptly gave to Tomura to use.

Hideout Raid Arc
After the Vanguard Action Squad's successful capture of Katsuki Bakugo and Ragdoll, All For One promptly stole the latter's Search Quirk. He then had Doctor Garaki once again replicate his Quirk, believing he may be defeated soon, receiving a copy of the All For One Quirk for himself, while the original was kept by the Doctor, with the intention of passing down to Tomura when he's ready.

After Katsuki attacks Tomura in defiance of joining their cause, Tomura understands that mere words alone won't convince Katsuki to join them and decides to ask for the "force" of his teacher to help him convince Katsuki. All For One, who has been watching Tomura on his computer, commends his apprentice for his wise decision.

The League of Villains is soon apprehended by the Pro Heroes and Police Force. All For One decides to take action himself, emerging at the Nomu manufacturing warehouse, and apologizes to Tiger, explaining that Ragdoll is in a comatose state because he stole her Quirk, Search, which he found to be quite useful. Best Jeanist restrains All For One with his Quirk and orders his fellow Pro Heroes to not let the villain do anything.

Before the Pros can act, the entire warehouse is completely destroyed and the surrounding area suffers extensive damage as well. All For One had unleashed a blast wave that had seemingly killed the Pro Heroes, destroyed the warehouse, and dealt significant damage to the surrounding area in less than a second. All For One is livid with the Heroes for interfering with his apprentice, who has started thinking for himself as well as leading others by himself and hopes they no longer bother him. All For One decides to quickly resolve the mess created by the Heroes.

All For One uses a Warping Quirk to produce a black liquid at the League of Villains' hideout; the black liquid summons dozens of Nomu inside and outside the hideout, forcing the Pro Heroes and Police Force to confront the legions of Nomu. This black liquid also teleports the League of Villains and Katsuki away.

All For One discovers the Pro Heroes have survived his attack. All For One claps and praises Best Jeanist for using his Quirk to pull his fellow Heroes out of the way in order to reduce the blast's impact on them. Despite his heavy injuries, Best Jeanist attempts to fight back and begins sending fiber strings. However, All For One impales Best Jeanist from afar. The mighty villain mentions that he does not need his Quirk because it does not suit Tomura’s personality.

Tomura, Kurogiri, the Vanguard Action Squad, and Katsuki all materialize from the black liquid in front of All For One. The villain sees that his apprentice has failed again, however, All For One is neither angry nor disappointed with Tomura and encourages him to try again since he still has the Vanguard Action Squad and Katsuki whom he deemed important. All For One implores Tomura to continue trying as many times as he likes since everything is for his sake.

Suddenly, All Might appears above him and attacks him. However, All For One blocks his attack, as All Might declares that he will take everything back while All For One wonders if All Might will attempt to kill him again.

All Might and All For One clash, which creates a shockwave that sends Katsuki, Tomura, and the Vanguard Action Squad backwards. Both All For One and All Might criticize each other for becoming weaker. All Might declares that he will save Katsuki and will not repeat the same mistake as he did six years ago and this time he will definitely put All For One behind bars along with the League of Villains. All Might charges at his arch nemesis, but All For One sends another huge blast wave at All Might, causing the Symbol of Peace to be sent flying away with great force. All For One's blast wave attack not only hits All Might but destroys several buildings in the process.

Katsuki becomes concerned, but All For One tells Katsuki not to fret since his blast wave attack is not strong enough to kill All Might. All For One orders Tomura to escape along with Katsuki and comments that his black liquid warping Quirk will not be able to help Tomura and the League of Villains escape. All For One uses a Quirk that forcefully activates Kurogiri's Warp Gate, which causes a portal to open. All For One orders the League of Villains to escape into Kurogiri's portal. Suddenly, All Might reappears onto the battlefield, refusing to allow the arch villain to escape and charges at him. Before heading into battle, All For One tells Tomura that he can still grow stronger.

All Might and All For One clash once again, while Katsuki tries to fend off some of the Vanguard Action Squad trying to apprehend him; All Might attempts to help Katsuki only for All For One to intervene and stop him. Suddenly, Izuku, Eijiro Kirishima, and Tenya Ida appear above them in the air; All For One sees the trio and attempts to attack them, but All Might intervenes by punching him.

Katsuki manages to use this opportunity to escape along with Izuku and his friends. Now that the tables have turned, All For One sees that they no longer can secure victory due to Katsuki's rescue and that most of the Vanguard Action Squad is unconscious. All For One decides to save Tomura and the Vanguard Action Squad, forcefully activating Magne's Magnetism Quirk. Before Tomura can stop, he and the Vanguard Action Squad are magnetically pulled into Kurogiri's Warp Gate. As he is being sucked into the Warp Gate, Tomura calls out to his teacher concerned for his safety. Before Tomura teleports away, All For One tells Tomura to continue the fight. Tomura and the unconscious Kurogiri are teleported away by the Warp Gate, causing the portal to disperse.

All Might charges at All For One, but All For One uses his Warping Quirk to teleport Gran Torino in front of him, using the elderly Hero as a human shield which causes Gran Torino to take All Might's attack instead. All For One expresses his hatred for All Might as he is the one who brought down his comrades in the past and while he descended into darkness, All Might rose to the top as the Symbol of Peace. All For One prepares to fire his blast wave move, intending to blow away Gran Torino and All Might at the same time. However, All Might pulls Gran Torino away and uses a Detroit Smash to cancel out All For One's blast wave move.

All For One sees that his destruction of the city has brought chaos and decides to put the innocent civilians in danger so that All Might will not be able to fight at full strength. Furious with All For One's sadism, All Might grabs his arm while throwing Gran Torino away for safety. All Might admonishes All For One for all the despicable crimes he has committed and for his misanthropy.

All Might punches All For One in the face, shattering his mask; however, All Might's punch was not strong enough to finish him off. As Gran Torino calls out to him, All Might's face reverts to its true form, reaching to his limits. All For One says that All Might would not be the first to criticize him as he has heard those same lines before, from the previous One For All successor: Nana Shimura.

All Might is angry at the arch villain for mentioning her name, as All For One notes that Nana was all bark and no bite, only going on about her ideals, and was not even strong; he mocks her for her uselessness and mentions that she died in an embarrassing, shameful way. Infuriated, All Might prepares to attack All For One, but he proceeds to use his blast wave technique against All Might, causing the hero to be blasted into the air. Gran Torino catches All Might and lands him to safety on the ground.

All For One decides to finish his apprentice's hard work and sever the trust in heroes once and for all. He once again expresses his hatred for All Might due to taking something away from him and wants him to die in the most gruesome way possible. He fires another wave blast attack at All Might, who, seeing that an innocent civilian is trapped under rubble behind him, blocks All For One's attack and saves the civilian from being harmed. However, All Might expends the last of his power and reverts to his true form. All For One relishes in the fact that All Might's true form has been exposed for all to see.

Everyone in the country sees All Might's true form and begins panicking. All For One mocks All Might for the pitiful state he is in. However, All Might does not care about his rotting body nor his exposure to the world and declares that his spirit burns strongly which is what truly matters. Wanting to break his spirit even more, All For One reveals that Tomura is Nana's grandson. All Might is completely shocked by the information and refuses to believe, but All For One tells him that it is the truth. All For One wonders why All Might is not smiling and sarcastically remarks about All Might's smile, which is something Nana would always do. All Might's spirit is greatly demoralized by the mockery while All For One continues relishing in All Might's pitiful state.

Invigorated by the civilian, All Might activates One For All throughout the right side of his body, transforming it into its hero form. All Might smiles and states that Heroes have many things to protect which is why they do not lose.

All For One deduces that All Might will unleash his final attack, commenting that wounded Heroes are the most terrifying of all. All For One's comment causes him to reminisce about their last battle where All Might delivered the final blow to him and admits that the look on All Might's face during that last attack has still haunted him to this very day. All For One prepares to fire his blast wave attack, when suddenly, flames strike at the mighty villain, which All For One uses another wave blast attack to swat away the flames with ease. All For One is surprised by the appearance of Endeavor and Edgeshot, specifically how they were able to make haste of the Nomu much faster than he anticipated, and that he shouldn't have taken Endeavor's No. 2 rank so lightly.

Annoyed with the Pro Heroes' interference, All For One prepares his blast wave attack again. However, Edgeshot uses his Quirk and great speed to attack, but All For One dodges the attack. Growing impatient with the sentimental talk, All For One blasts Endeavor and Edgeshot back and activates a number of his strongest Quirks in his right arm, causing it to become an enlarged mutated arm filled with numerous deadly screws and hardened minerals.

All For One charges at All Might with his heavily empowered and mutated arm. While heading towards All Might, All For One knows from battling him means All Might no longer has One For All, and that he is simply fighting with the remaining embers that have all been extinguished. He further tells All Might that he knows to whom he gave One For All to: Izuku Midoriya, having deduced it from Tomura's report about the boy. All For One taunts All Might by saying that he has also failed as a teacher towards Izuku due to his apprentice's recklessness and prepares to kill him.

Both All For One and All Might clash by punching each other with their enhanced fists, which creates a huge shockwave that devastates a great portion of the city. As they struggle, All For One uses his Impact Recoil Quirk to revert all the damage to All Might. However, All Might transfers One For All to his other arm, sacrificing his right arm but renders Impact Recoil ineffective.

All Might says that he must indeed criticize Izuku for his actions, while All For One is shocked that All Might would go to such lengths to protect his leftovers of One For All and admits that he miscalculated. All Might refuses to die until he has finished bringing up Izuku, and then counters by throwing his empowered left arm and punches All For One who has left his guard open.

The punch, however, was meant to lower All For One's guard, and All Might transfers One For All to his right arm and prepares for his final attack, United States of Smash, which creates a great shock wave when it hits All For One, destroying half of the city. After the dust clears, All For One is in a crater, badly beaten and unconscious. Later, Endeavor and All Might watch All For One being placed in the iron maiden.

The next day, All For One is incarcerated into Tartarus, a special prison for criminals for whom the death penalty is not enough. All For One, in a wheelchair and on life support, wonders where he is, much to the prison guard's annoyance who is pushing him to his holding cell; the prison guard tells him his location. All For One apologizes, causing the prison guard to assume that he is blind. All For One reveals that for the past six years he has been using an Infrared Quirk to sense his surroundings as a way to compensate his blindness, but due to all the sensors he is unable to sense anything and apologizes to the prison guard. The prison guard is flabbergasted that All For One fought All Might in such a condition.

While being pushed to his holding cell, All For One is not angry or upset for losing against All Might. Instead, All For One is happy because his defeat at All Might's hands will grow Tomura's hatred for All Might as well as his regret for being unable to save his master, which will motivate him to gain experience and become much stronger. All For One smiles, knowing that even though he lost the battle, he still will succeed at being the better teacher than All Might, and that his successor will come out on top.
