All For One/Relationships

Yoichi Shigaraki
Yoichi Shigaraki is the younger brother of All For One. In the past, All For One deeply loved and cared about his younger brother, as he was the only family he had.

However, All For One would insult Yoichi, labeling him as pathetic and fragile as he had his bodyguard go easy on him before imprisoning him. In return, Yoichi had a strong sense of justice and did not back down from opposing his brother's evil deeds.

All For One refused to kill his brother and instead imprisoned him, in hopes he would join his side. To end his rebellion and make him powerful, All For One attempted to get him to submit by giving him a Quirk that even his frail body could handle, unaware that his brother already had one and his act only contributed to the creation of One For All.

Yoichi attempted to defeat him with his newly merged Quirk (now called One For All), but lacked the sufficient power to do so.

It is unknown if All For One killed his brother in battle, but the latter's Quirk was passed down to a vigilante, in the hopes that someone in the future would eventually stop his evil older brother once and for all. Because of his brother passing on the Quirk, All For One sought One For All with each successor failing to defeat him. Once confronting the second user, Kudo, he cried genuine tears upon learning that Yoichi was dead, proving that, despite having imprisoned him, he still genuinely loved his little brother.

One century later, All For One meets Yoichi in the world of One For All, when Tomura attempted to steal the Quirk from Izuku. All For One rebukes Yoichi's decision to remain with Izuku, calling the latter unworthy of such incredible power. Yoichi retorts that All For One can never comprehend Izuku's resolve of self-sacrifice and that is the reason One For All will follow the young hero. Yoichi and Nana Shimura expel All For One and Tomura from the world of One For All, thwarting their attempt to steal the Quirk yet again.

After stealing New Order from Star and Stripes, All For One thinks back to Yoichi, and when they used to read comics, stating to his little brother he always knew there was more, but he simply chose to stop reading it, and now that he's gained the power of New Order, he's just one step closer to his dream.

It's possible that one of the reasons All For One desires One For All, besides its power, is to reunite with his younger brother through his vestige, since he failed to bring him to his side in the real world. Hawks himself would eventually confirm this to be the reason why All For One wants the Quirk so bad.

One For All Predecessors and Successors
In more ways than one, All For One is the arch-nemesis of One For All. When his brother, Yoichi acquired the Stockpiling Quirk after he forcibly gave it him, he inadvertently created the One For All Quirk, and sought to obtain it for his own benefits. Due to his brother's strong willpower and sense of justice, All For One was obsessed to acquire One For All no matter the cost. After Yoichi, at this point, every successor of One For All is the archenemy of All For One, which also makes him their deadliest enemy.

Kudo
At the peak of his power, All For One was opposed by Kudo, who formed the resistance against his new world order. At first, it appeared he didn't care much about the rebellion leader, as he saw him as insignificant and weaker than him, and just allowed his growing number of subordinates to deal with the resistance. However, Kudo caught his attention after he and the future Third User saved his younger brother and acquired One For All, and decided to target him because of it.

Kudo bears a strong hatred against All For One and did everything he could to fight back, even taking the lives of those who got in his way, but he wasn't strong enough to defeat All For One who crushed him and the resistance, before proceeding to choke him to death. During this, Kudo revealed to All For One that his brother Yoichi was dead, something that drove the Demon Lord to tears.

All For One displays scornful emotions and contempt towards Kudo and mocked him by calling his Meta Ability weak as it was only meant to work on small objects, being nothing more than a "peashooter", and how all he was only ever an insect in his path. He calls Kudo a stuck-up pompous brat who didn't even squirm at the last moments of his life.

Yet, All For One remembered how Kudo simply smiled down upon him with satisfaction, as if he was mocking him with pride in knowing that he had failed to steal One For All before eventually killing him. Despite triumphing over Kudo, his memory of him still appears to affect All For One to this day.

Over a hundred years later, with All For One taking control of Tomura Shigaraki's body in the U.A Flying Sky Fortress in the Final War Arc, he wonders why he is panicking so easily over an "extra" who doesn't possess One For All, and sees a blurred visage of Kudo in front of Katsuki as a reminder before Tomura killed him. And later again when Katsuki proclaims himself to be All For One's final boss.

Over the course of his fight with Katsuki, All For One notes that the intense hatred he carries for Kudo is because, if not for him reaching his hand out to Yoichi, One For All would have never existed, and all his troubles are a direct result of that interference. He goes on to proclaim that Kudo is the one person he despises the most, even more so than he does All Might.

Third User
The Third User joined Kudo as a part of the resistance who fought against All For One and his new world order during the peak of his power. Not much is known about the Third User and his confrontation with All For One, but it is implied that he was killed by All For One just after he passed One For All on to Hikage Shinomori.

Hikage Shinomori
Hikage became the fourth successor of One For All.

Unlike Kudo and the Third User of One For All, Hikage lived during the era when society was in chaos and All For One was at his prime. He was twenty-two when he inherited One For All from the Third User, along with the mission to defeat All For One.

However, Hikage was aware that given the huge difference in their combat abilities, and power levels, he could never defeat All For One. He chose to avoid fighting All For One, and instead cultivate One For All in seclusion. Over the next eighteen years, Hikage strengthened One For All with rigorous training. When he turned forty, Hikage's body began to deteriorate and showed signs of old age. Confused by the rapid aging, Hikage entrusted One For All to Daigoro Banjo before passing away.

All For One could never find him and continuously searched for him and his successor, Daigoro.

Daigoro Banjo
Daigoro was entrusted with One For All by Hikage.

Daigoro bears the same hatred against All For One because of his evil schemes and deeds that threatened the world and harmed the innocents, even calling out his diabolical plot to take over Tomura's body and turned him into beyond saving. Given that he resisted having One For All stolen by All For One, Daigoro presumably has an extremely strong willpower. Yet, despite that, Daigoro wasn't strong enough to defeat All For One. He attempted to steal One For All from Daigoro, but failed, and Daigoro was killed by All For One after transferring One For All to the sixth user, En.

En
Like his predecessor, En was chosen to be given with One For All, making him All For One's sixth archenemy.

Like Daigoro, En refused to give One For All to All For One and resisted through his strong willpower. Eventually, All For One killed him, but not before En had passed on One For All to the seventh successor, Nana Shimura.

Nana Shimura
Nana Shimura became the seventh user of One For All after En passed it on to her.

All For One is scornful of Nana Shimura. He mocks her commitment to ideals and disparages her strength and, by his admission, declared the latter died a pathetic death. He was so contemptuous about Nana that he used her name as a form of mockery to her successor, All Might, enraging the hero in the process.

All For One tarnished her memory by knowingly taking in and grooming her grandson to be his successor.

All For One meets Nana in the world of One For All and insults her in front of Tomura. Nana recognizes her grandson and isn't pleased with the situation. She and Yoichi Shigaraki work together to thwart All For One's attempt to steal One For All.

All Might
Like all the predecessors before him, All Might is the archenemy of All For One, which also makes him his eighth enemy.

All For One and All Might loathe one other. All For One holds a deep hatred for All Might for crippling him, defeating his comrades, denying his ambitions, and being called the Symbol of Peace for this. All Might sought retribution against All For One for murdering his master. It is revealed that All For One viewed All Might as huge threat who could defeat him and groomed Tomura to succeed him.

He states to All Might that he needed a successor because of the injuries All Might inflicted on him from their first battle. Due to the crippling injuries All For One received, he can never be in his prime again. It's also heavily implied that All For One is in even worse shape than All Might is. While All Might's injuries limited his use of One For All, All For One is not capable of living without a life support apparatus keeping him going.

During their second battle during the Kamino Incident, All For One confesses that he still has nightmares and mental trauma from their first encounter from when he saw the look on All Might's face after ripping All Might's guts out. All Might seems to not only be the first to defeat All For One, but also the first to ever severely scar him mentally.

All For One enjoys belittling and ridiculing All Might, even relishing in breaking All Might's spirit by revealing that Tomura is Nana Shimura's grandson. He also enjoys watching All Might become riled up by belittling Nana's heroism and death. In their second battle, All For One aims to take everything from All Might, his image, and pride by revealing his gaunt form and weakness to the public.

Even after being captured, All For One continues to play with and taunt All Might, using any and every opportunity to strike at his nemesis. Despite being defeated by the latter, All For One took his loss in stride and mocked All Might for not dying when he had the chance, confident that his pupil will become stronger to take over the League of Villains. All For One is also aware of the fact that Izuku Midoriya is the current bearer of One For All and criticizes All Might for being a pathetic teacher.

While All For One was imprisoned in Tartarus, his interest in All Might waned as he set his sights on the ninth user of One For All: Izuku Midoriya. Despite this, he continues to feel spite for him, raging at how he continues to inspire heroes like Star and Stripe, and quickly realized the plan to split him and his army up when he confronted Izuku at the parking lot was a strategy All Might came up with.

Due to the instability from melding Tomura's mind, when All For One encounters All Might on his way to Tomura, the villain is unable to resist the sheer amount of hatred he carries for the hero. All For One looks down on him grinning with madness in his eyes, gleefully excited that he can settle the score with his old archenemy for the last time.

Over the course of their final battle, All For One acknowledges All Might as the number one hindrance in his life, and can't resist attacking the armored hero once he sees his trademark smile. All For One continues to mock All Might over the course of their fight, constantly deriding him as trash and how foolish he is for believing that wearing his "trash bag smile" would allow him to stand against him. However, All For One's hatred for All Might is what allows the fight to take place to begin with, as he had a chance to kill All Might by crushing his skull but instead disabled his legs, so he could see it when All Might finally stops smiling. Eventually All For One manages to destroy the suit and intends to carry the injured hero to U.A. for the whole world to see his failure. Just then All Might grabs All For One with his remaining gauntlet for a last ditch attempt to blow them both up.

However, learning from past experiences that All Might is most dangerous when wounded, All For One thwarts All Might's suicidal attack, to allow his old enemy to die "a heroic death." Realizing that All Might had used his last trick, All For One paralyzes him with Bloodcurdle, and grins excitedly as he sees the face he's been waiting for all this time: All Might in absolute despair and at his very lowest point. Just before he can rip All Might apart in front of the entire world, he is narrowly saved by the combined effort of Katsuki Bakugo and Izuku Midoriya.

Izuku Midoriya
While he and Izuku went a long time without directly interacting, All For One has made it his mission to hunt down every One For All wielder he can find in an attempt to steal the Quirk and make his brother, the original user, become one with him. When Izuku became the ninth and final user of One For All, it makes All For One his most dangerous foe alongside Tomura, as he inherits him as a nemesis by accepting All Might's power.

Once All For One deduced that Izuku was All Might's successor, he prepared to crush the boy's heroic spirit with an all-or-nothing plan to destroy him and acquire One For All at last. During his time in Tartarus, All For One lost interest in All Might and moved on to Izuku, fantasizing about tormenting him. Izuku, on the other hand, knew there was a chance he'd have to go up against One For All's mortal enemy someday even if the details of the supervillain's plan wouldn't be deduced until months after his imprisonment.

Upon witnessing All For One in the flesh, Izuku felt overwhelming fear, seeing visions of him and his friends dead by his hands. Izuku's feelings toward All For One became extremely spiteful near the end of the Paranormal Liberation War, when the latter takes over Tomura's body and stabs Katsuki, following it up with dismissing the efforts of all the heroes trying to stop Tomura as "pointless". Enraged, Izuku lost his calm and went straight toward Tomura/All For One, leaving him vulnerable to getting One For All stolen.

In the vestige world, All For One mocked Izuku's altruism as a weakness and claimed that All Might made a mistake choosing him as a successor. Yoichi and Nana, however, fought back against him, rebutting that Izuku's perceived weakness is exactly why he was chosen for this power. All For One fails in stealing One For All, and while he acknowledges Izuku as a threat to his plans, he is still dismissive of the young hero.

All For One finds Izuku to be predictable, and exploits this quality to try and break Izuku's spirit. He anticipated that Izuku would reach out to Lady Nagant, so he detonated her using the bomb quirk he'd planted into her in secret. He also left a video message at the former Creature Rejection Clan hideout when the heroes investigated it, telling Izuku that society will always exclude certain people and label them villains, so he is fighting an endless and ultimately pointless battle. All For One's manipulation makes Izuku paranoid to the point that he doesn't try to reach out to other villains he sends his way and begins working alone, making civilians fearful of the hero. His attempts to exhaust and isolate Izuku were thwarted when Class 1-A brought him back to U.A., though he shrugged it off.

Izuku's hatred toward All For One would grow further when he learns that he forced Yuga Aoyama to become a mole for him, endangering the students' lives numerous times. He and his classmates become newly determined to defeat All For One in the coming battle to decide the fate of the world. He and Aoyama ended up drawing him out to a secluded parking lot, whereupon All For One summoned his army of villains in a moment of arrogance and allowed the heroes to spring their counterattack using Warp Gate.

Upon encountering each other again at the floating U.A. High School, All For One jeered at Izuku over the death of Katsuki and the heroes' devastating injuries. Izuku once again lost control of his emotions and was in severe danger of All For One breaking his spine until Mirio calmed him down, informing him that everybody else was still alive and that Katsuki could possibly be revived by Edgeshot. Remembering Banjo's words about controlling his anger, Izuku was able to keep his cool and prepared to fight, asking All For One if Tomura still remained after his forceful merger with him.

All For One, while unaware Izuku was trying to save Tomura, still sensed he had a plan to defeat him that involved the young man, so he bluffed by saying Tomura was gone and that he was the dominant personality. He was quickly proven to be lying by Mirio, prompting him to lunge at Izuku in another attempt to steal One For All, knowing his control over Tomura weakening meant his window to take back the Quirk was dwindling. However, Izuku had unlocked Gearshift, which allowed him to move far faster than Tomura's body afflicted by Erasure could keep up with. All For One was left stunned and unable to move by Izuku's attacks, expressing his petty hatred for him and the heroes before insisting he hadn't lost just yet, vowing that victory or defeat for heroes and villains would be decided very soon.

Tomura Shigaraki
All For One groomed Tomura as his successor. He was the one who found and rescued Tomura from the streets after the incident of killing his family during his childhood even giving him his surname after renaming him.

It's later revealed and heavily implied by Yoichi that the main reason All For One groomed Tomura to be so hateful of the world and of All Might was in order to foster a hateful will; through a stronger willpower, it would be possible to overcome the will of a One For All user, bypassing it's natural resistance to being stolen.

All For One is deeply invested in Tomura's growth and was pleased when Tomura finally developed a plan to achieve a goal on his own. Although well aware of his immaturity, he works to mold him into the successor he dreams of him being. When the police and Pro Heroes capture Tomura, All For One retaliates with force before teleporting Tomura and his friends to safety.

It is unknown whether Tomura is aware or cares that All For One killed his grandmother, however, it does appear that All For One truly cares for Tomura, having a similar relationship like All Might has with Izuku. All For One even allowed Tomura to carry on his family name, Shigaraki, when renaming him. Instead of punishing Tomura as any archetypal villain would do to their apprentice, All For One instead encourages Tomura to simply start over as many times as he needed to and that he will always provide him with help. His care goes so far as to urge Tomura and his friends to leave the battlefield with All Might, keeping the Symbol of Peace distracted and entrusting Tomura to continue the fight in his stead.

Although All For One groomed Tomura with the intention to demoralize All Might and even scorn the lineage of Nana Shimura, it is evident that he supposedly grew to care for his adoptive son and is the only person to whom he has shown genuine love to, besides his brother, even if greatly motivated by evil.

After Tomura received the All For One Quirk, All For One (or at least a vestige of him in the Quirk) attempted to take control of Tomura's body, and use it to steal the One For All Quirk from Izuku during his battle with him. Tomura regained control and rebuked his master, saying he wanted to follow his own will, and become greater than he was.

Tomura begins to resent All For One when the latter repeatedly attempts to take over his body to steal One For All. All For One doesn't mind though as he cheers on Tomura while he resists his control as it proves that Tomura is strong enough to be his successor. He later advises Tomura to retreat and let his body heal while he waits for his body to adjust to his new power. As the battle continues, however, All For One once again takes control of Tomura's body, noting that the more hatred Tomura has in his heart, the more his consciousness takes hold of his protege's body. All For One remark how Tomura should pay back for losing to Endeavor and Deku, saying that it is all for his sake; this implies that All For One only saw Tomura simply as a crux to regain power and had no true affection for him.

This is further shown when he called himself in Tartarus his "real body", implying that he sees Tomura as nothing more than an additional host for his consciousness. When Tomura attempted to regain control, All For One refused, stating that this was the fruit of Tomura's labors, and when he refused to be a pawn, All For One replied that he was no mere pawn and someone very "near and dear to him". However, when he finally escaped Tartarus he stated that this is the story of how he would become a more perfect demon lord. This heavily implies that he had no affection for Tomura, and after his body was heavily damaged by All Might, he spent all those years of raising him and nurturing his hatred in order to both gain a new, healthier and stronger body and use Tomura's hatred in order to steal One For All thus allowing All For One to rise once again by taking permanent control of Tomura's body giving him even greater power than before.

This would make sense as All For One is notorious for manipulating people for his own benefit and often enlightening them with false promises and motivations.

In spite of this, when conversing with Spinner, All For One said that he greatly respected Tomura's will, and that once Tomura's body healed, all their desires would come to fruition; this could insinuate that even if All For One never cared for Tomura personally, at the very least he respects Tomura and his resolve, as well as the wishes of his allies, although he could have just told this to Spinner to put him at ease. Additionally, while All For One is trying to remake himself using Tomura's body, he is also seemingly okay with Tomura being stronger than him. At the very least, he is reluctantly willing to let Tomura usurp him as the true user of All For One and the Symbol of Evil if it comes to that, but Tomura must prove himself to be stronger.

It is eventually revealed that All For One wishes to merge his own consciousness with that of Tomura's so they can both combine into a stronger, evil entity altogether. While Tomura is vehemently against this and continues to fight his former master's control, All For One praises his former protégé while saying that all the hatred he had built up over the years is speeding up the process of his new body's completion and them combining to become the ultimate evil. At this point, All For One expresses a twisted form of pride towards Tomura, praising him for exceeding his expectations yet willing to fuse with him against his will.

Some time after, All For One realized that while his merging with Tomura was indeed a success, it came with the drawback of his original aspect as Tenko Shimura creating a "fissure within" that actively resisted him. All For One never growing aware of this until his confrontation with the heroes at U.A. High School proved the self-serving nature of their relationship, and his attempts to keep Tomura under control against his will showed he doesn't actually care for the boy himself, and will use him like he uses anybody else to accomplish his goals.

During his confrontation with Hawks, All For One reveals that he never intended to have a shared consciousness with Tomura and had planned to take full control of his body, but Tomura's hatred forced a mental fusion between his vestige and Tomura. All For One's end goal was to have Tomura absorb the Quirk Factor of the second All For One Quirk, allowing him to have full control over Tomura's body and permanently suppressing his personality.

Kyudai Garaki
All for One puts deep trust in his physician, exclaiming that Kyudai's insatiable curiosity and inquisitive nature has always been the source of All for One's strength, and thanks the doctor from the bottom of his heart, going so far as to call him his friend.

All For One met Kyudai when he was at his lowest point, after being ostracized from society due to his Quirk Singularity theory. All For One, on the contrary, believed in his theory and gave him his full support. Thanks to this, Kyudai became one of his most loyal followers, giving him his original Quirk as proof of this. Since then, Kyudai has worked as All For One's personal doctor.

All For One tasked Kyudai with several assignments like making Nomu, searching for Quirks for him to use, and overseeing Gigantomachia, among others. All For One is the only one that Kyudai entrusts with his 'children' (Nomu) and the knowledge of his appearance. Kyudai was also the one who treated All For One's injuries, using his talents as a doctor to help rebuild All For One's body after his battle with All Might.

Dabi
When All For One was scouting for more vessels to replace Tomura should he ended up dead or become inadequate, he found Toya Todoroki at the lake near Sekoto Peak, but the latter was left with severe degrees of burns all over his body and barely alive, but breathing. He sees the boy's potential in his Blueflame and took him to have his body treated by Kyudai. It was a long process of recovery that Toya was left in a comatose state for three years. In order to restore his burnt body, his missing pieces had to be replaced with regenerative tissue, however All For One became aware that he'll be unable to utilize the power he once had, with his organs damaged, body debilitated, and senses all dulled, unable to feel pain.

He intended to welcome him back at his full strength, but with so much damage to his body, All For One believes that Toya was another failure, which causes a visceral reaction in Toya. Despite how much of a failure Toya is, All For One was willing to restore his fire to its former glory, asking if he will allow him to raise him. However, Toya viciously denies him, saying he has no intention of being trained by anyone else. Toya doesn't want All For One to be his master, and thus, All For One was unable to exploit his obsession with his father. Since that boy never bought what they were selling, All For One decided to let him go because his body shouldn't have lasted a month, however, Toya saw the results of his "death" and was reborn as Dabi, essentially coming back to join the League of Villains half a decade later. All For One was surprised by his survival and had him recruited to discover how it was possible.

All For One is amused by Toya's hatred for his father and acknowledges his deadly skill. Before the Final War, he also offered to give Dabi more power in the form of another Quirk, but the younger villain refused without question.

All For One later taunted Endeavor about his role in Toya's disappearance, gloating of how he is responsible for him becoming Dabi.

Kurogiri
All For One ordered the creation of the Nomu, Kurogiri, using the body of Oboro Shirakumo. Although programmed to obey his commands, and the memories of his past life suppressed, All For One granted him with intelligence of his own and some traits of his former self's personality was retained, especially Oboro's caring traits and his drive to help others, especially people close to him.

All For One wanted to create Kurogiri in this way because he entrusts him into looking after Tomura and ensure that he is given the proper guidance. He also told him the location where he hid Gigantomachia in case he needed it to protect Tomura.

In the few interactions that are seen between the two of them, All For One shows some respect and appreciation for Kurogiri despite being a Nomu, valuing his honest opinions. During the Underground Masquerade Incident, All For One tried to teach Kurogiri the dichotomy between heroes and villains, and how the relationship between a person's will and their Quirk is what defines one and the other.

Gigantomachia
Gigantomachia was his bodyguard when All For One controlled the world from the shadows and said loyalty has not waned despite All For One's downfall. For his part, All For One considers Gigantomachia an essential piece for Tomura and the resurgence of the League of Villains. Because of this, All for One hid Gigantomachia in the mountains as a means to help preserve his dreams.

However, the same loyalty to All for One that makes Gigantomachia useful also makes him difficult to control for others. He initially refuses to accept Tomura as his successor because he believes that Tomura is not All For One's equal. It is noted that a recording of his master's voice can quickly soothe him to the point that he will purr. However, he came to accept Tomura after seeing his reawakening in action.

In spite of Gigantomachia's unyielding loyalty to All For One, he still chose to abandon Gigantomachia; once when he had to go into hiding, and for a second time when he left him along with Mr. Compress and Himiko Toga during the Paranormal Liberation War. Despite All For One assuring Gigantomachia that he would miss pampering him, this shows that the villain largely takes the behemoth's loyalty for granted, suggesting that he only sees Gigantomachia as dispensable as the rest of his followers.

This decision would later come back to haunt All For One during the Final War. As Gigantomachia arrived on the battlefield, All For One was shocked to see the behemoth attack him of his own free will, after freeing him from Hitoshi Shinso's Brainwashing. Gigantomachia expressed his heartbreak at his master's abandonment of him, and instead threw an all-out assault at All For One as revenge. In return, All For One retaliates by firing a giant blast of lightning at Gigantomachia, destroying half of his body and taking him down along with the Heroes.

Lady Nagant
Following the Tartarus prison break, All For One meets the Ex-Pro Hero as she carries along a catatonic Kai Chisaki. All For One humbly greets Lady Nagant, saying that its an honor to meet a traitor of the heroes while Nagant smiles, recalling that she had targeted him in the past. All For One asks Lady Nagant to capture Izuku Midoriya for him, complimenting that her skill far exceeds that of the other escapees. While at first she refuses, prioritizing her escape, All For One manages to convince her by saying that the Hero society will never see its downfall as long as Izuku is around. Lady Nagant ends up accepting his request, and All For One gifts her his Air Walk Quirk to assist her mission and to seal the deal between them.

However, All For One predicted that Lady Nagant would either be defeated by Deku, or would be swayed into helping the young hero, remarking on how the human soul is far too fickle. Foreseeing Lady Nagant's betrayal, it is revealed that he also gave her a Self-Destruct Quirk along with Air Walk to act as a failsafe. After said Quirk detonated from within Nagant's body, almost killing her in the process, All For One smiled and said that in the end, she was just a tool for him to use and went as far as to say that she should blame her own Quirk for it. Later on, All For One would mock the former hero's choice in helping him towards Izuku, saying that he couldn't resist tempting her and then remarked on how she acted completely of her own free will in assisting him and paid the price because of it.

In the end, All For One had manipulated Lady Nagant to do his bidding before disposing of her, as he has done with countless other people.

During the Final War, after Lady Nagant returns and shoots "Tomura" in the hand to prevent him from using Decay, All For One's vestige is enraged to discover that she's alive, causing the villain's spiritual counterpart to accuse her of playing the victim by helping the heroes and calling her an aimless weakling.

Endeavor
Out of all the heroes he has faced, he has sincere respects for Endeavor for rising up to becoming the No. 2 during the fight with All Might at Kamino. It was a rare thing for All For One to have some respect for heroes and Endeavor was one of them. Essentially, he sees Endeavor as a hero would become obsessed with surpassing All Might in terms of strength and power, and recognizes him as a man of power. Nonetheless, he still treats Endeavor as nothing more than nuisance like all the other heroes.

All For One mocks Endeavor for failing his role as a father, and having Shoto face off against Dabi, one of the strongest villains in the army. He often wonders why Endeavor would allow his youngest son to deal with his eldest when he knows that it was all because of him that lead Toya to become Dabi in the first place.

When he fights against him and the heroes, Endeavor and the Heroes receive word that Dabi has been defeated by Shoto, causing him to react. In response, All For One comments on Endeavor's face, taunting him that he allowed his youngest son to take the burden of defeating his eldest sibling. Hawks tells Endeavor not to listen, expecting his upcoming verbal assault, while All For One continues, berating him for not even looking at Toya and letting Shoto handle everything, confidently stating that is why he'll never win. To further pester the hero, All For One revealed his role in Toya's disappearance, allowing him to catch the enraged hero off guard and attack him.

Endeavor remained out of the fight for a few minutes more, whereupon Kyoka Jiro and Fumikage Tokoyami took his place. Their efforts gave Endeavor the time he needed to get back on his feet, furiously launching back into battle and taking All For One away from where he could hurt them and Hawks. When Endeavor claims that All For One has done nothing but destroy lives, the villain retorts back by saying that Endeavor is no better than he is. Endeavor accepts this however, acknowledging how his past actions have harmed everyone involved and resolves that he will continue to atone so the next generation of heroes won't be burdened by his mistakes. He burns All For One to a crisp, pushing the supervillain to employ his last trick and use Rewind on himself, a move All For One acknowledges shows Endeavor had pushed him past his limits and essentially forced him to sign his own death warrent.

Hawks
All For One battled Hawks when he was split up from his army, the hero assigned to chip away at his mask in order to weaken him while Endeavor kept All For One preoccupied with heavier attacks. All For One eagerly took the challenge on, knowing that revealing his involvement in pushing Toya to villainy would enrage Endeavor and leave Hawks alone. When he put this strategy into effect, he tried to kill Hawks, but failed when the hero was saved by Kyoka and Fumikage.

All For One now contended with several new combatants, shifting from Hawks to the kids as his new targets. Hawks having an obligation to watch over the students was something All For One took advantage of, as he mercilessly attacked Kyoka and Fumikage. When Kyoka managed to stir the vestiges inside All For One's copied Quirk to action, this gave Hawks the opening he needed to finally shatter his mask to pieces. Stunned, All For One flew into a fit of childish rage, flinging Rivet Stab in multiple directions and forcing Hawks to move in front of the kids to protect them, with Endeavor launching into the air just in time to protect them all from getting stabbed.

After All For One regenerated to his prime with Rewind, he dropped to the ground and stole an unnamed female hero's Quirk and cape to clothe himself. He shrugged off Hawks' slash across his face as it naturally rewound on its own. Hawks, stalling for time so Endeavor could wind up for one last attack to finish him off, stoked All For One's ego and got him to speak about his motivations. All For One revealed to him his true goal beside stealing One For All was to be seen as the ultimate evil that everybody could universally hate no matter their background, and "thwart the future of the whole world."

Once the heroes lay broken and defeated at All For One's feet, Hawks feebly resisted the villain in the hopes of protecting his protege Fumikage Tokoyami from losing his quirk. While holding the nearly eviscerated winged hero by the throat, All For One begrudgingly acknowledges how far Hawks managed to push him, despite possessing such a crippled quirk factor. Hawks continues mocks the villain before All For One steals his quirk and tosses him aside, spitefully informing them soon the public will know that once again the heroes failed to protect everyone before racing off to Tomura.

Best Jeanist
They first encountered each other during Kamino Incident, where Jeanist quickly saved his allies from All For One's attack, though at the cost of being wounded.

In response, All For One praises Best Jeanist's skills and proficiency with his Quirk. However, he deems that his Quirk requires too much skill and therefore it's useless to him. Despite Best Jeanist's attempt to attack him, All For One blasts a gust of air that, in the long run, costs Best Jeanist a lung. Best Jeanist is terrified of All For One's sheer power and skill.

Star and Stripe
All For One recognizes Star and Stripe as a huge threat to his plans of global conquest. Upon hearing of her sudden arrival, he decided to fight her himself despite Tomura's body not being fully ready, out of fear of her collaborating with Izuku Midoriya. The fact that he planned to steal One For All before confronting her proves how much of a threat All For One viewed her as. During his fight with the hero, he becomes eager to test out the limits of her Quirk, New Order. After she unleashes her final move upon "Tomura", he admits that any other move would've finished him, but then derides her over her failure while saying he would make better use of her resources.

After stealing New Order, "Tomura" mocks the hero by agreeing with the pilot who called her an idiot. However, before he prepares to use New Order, All For One sees the vestige of Star and Stripe going wild, tearing apart the other vestiges and destroying "Tomura's" body, thanks to the last minute rule placed onto New Order which caused it to revolt against other Quirks. All For One is infuriated, completely caught off-guard by this and unable to do anything to stop New Order from destroying his body. In the mental world, All For One curses her, viewing her as the specter of All Might. Star and Stripe is the only hero besides All Might that has managed to make All For One lose his composure.

Yuga Aoyama
As Yuga was born Quirkless, All For One was visited by the Aoyama parents and he bestowed upon the young boy Navel Laser. Years later, All For One decided to collect on this debt and had Yuga become his mole within U.A. High School. To that end he forced the young man to relay information to him whenever it was convenient, leading to both the U.S.J. Incident and the Vanguard Action Squad Invasion.

All For One has no regard for Yuga, seeing him and his parents as expendable pawns, and going as far as to compare Yuga to a cheap lighter that would eventually fizzle out and stop working. He threatened Yuga and his parents with death should they have disobeyed or lied to him, and even showed them an example of what became of someone who once ratted him out; a man who went to the police and was killed when he was released from prison. As a result, All For One had sewn a strong fear into the Aoyama family, as well as a strong and horrible guilt within Yuga for having betrayed his classmates and putting them in danger.

In return, Yuga heavily resents All For One for exploiting him and his parents. He confided in his parents that he believed he was free upon witnessing All Might defeat him during the Kamino Incident, believing that he could move on and become true friends with his classmates. However, these hopes were dashed after All For One broke out of Tartarus.

Upon contacting Yuga's family, All For One puts on his normal benevolent guise, addressing them like family relatives and greeting Yuga as though he was his nephew. After Yuga seemingly betrayed Izuku by delivering the U.A. student to him, All For One congratulated Yuga on accomplishing the task he gave him, commenting on how hard it must have been for him to betray his friends yet again while also commending him for his speech about his final plan (although it wasn't completely accurate). All For One promised Yuga that him and his parents would have a happy life in his new world. After his plan looked as though it came together however, Yuga turns on All For One and blasts him with his Navel Laser, revealing this was just a ploy orchestrated by U.A. that Yuga and Izuku went along with. After being betrayed by his unwilling spy, All For One angrily calls Yuga an ungrateful wretch and summons his PLF forces, initiating the final war between heroes and villains.

Katsuki Bakugo
All For One had known very little about Katsuki even when Tomura went to the trouble of kidnapping him, which he exploited to lure out All Might and force him into an early retirement. However, he began to take an interest in him after Izuku's furious reaction to stabbing him, realizing his death would further torture the final One For All wielder. Thus, he began focusing on him as a priority target in his attempts to compromise Izuku's willpower and steal back his brother's Quirk.

During the battle on the floating U.A. High School, the All For One vestige inside Tomura's body engaged Katsuki and the other heroes in a deadly battle, able to grievously injure them with Izuku absent thanks to Himiko pulling him away before the fight could begin. He espoused to Katsuki his vision of a world that was truly equal in universal poverty, with him alone at the top enjoying the spoils. He also came to inform Katsuki of his intentions to kill him as a way of hurting Izuku, and that all he amounts to is a "minnow in One For All's wake."

Katsuki, realizing All For One wouldn't stop until he killed him, chose to stand his ground and fought him head-on after developing full body explosions, reflecting on his own relationship with Izuku as he fought. All For One suddenly became unnerved by Katsuki's speed, reminded of the second One For All user, before striking the killing blow out of fear, leaving Katsuki dead. Regaining his composure, he gloated over Katsuki's death until seeing Edgeshot attempt to revive him, whereupon Tenko's indignation over never being saved prompted him to leap forward in a fit of rage.

He continued to wreak havoc on the remaining heroes until Izuku arrived. All For One wasted no time to inform Izuku of Katsuki's death, which had the desired effect of making him lose himself to anger when combined with the other injuries he'd inflicted on the heroes. He became irritated once Mirio informed Izuku that Katsuki could possibly be saved and the other heroes were still alive, his investment in targeting the boy ending up far less effective than he had been hoping for.

Later once Katsuki finally awakens, he is able to narrowly save All Might from a gruesome demise at the hands of All For One. Blood Boiling at Katsuki's interference he nearly attacks them before realizing he can't waste anymore time as he needs to finally get his brother and One For All. Fortunately his anger leaves him open for a point blank explosion from the young hero, as flashes of Kudo flash through All For One's mind once again. During their battle, All For One scoffs at Katsuki's attempts to stop noting he isn't on the same level as Endeavor or Dark Shadow, and it's just pathetic comparing him to All Might, and trying to reaffrim that he is simply a pebble in his path. He finally realizes that the reason he is so vexed by Katsuki is due to his resemblance to the second user of One For All: Kudo.

Kyoka Jiro
All For One came across Kyoka during the battle over the Gunga Villa ruins when Endeavor and Hawks had tried to take him on away from the other heroes in a more concentrated attack strategy. Following his successful provocation of Endeavor's anger leading to him taking a chunk out of his side, Kyoka swooped in on Fumikage's back to push Hawks out of harm's way. All For One described the two students as merely "jobber characters", but Kyoka defiantly told him to save it until after he had actually managed to beat them.

The villain king continued to mock Kyoka, calling her a deluded extra as he focused on attacking her as a weak spot with full intent to kill her. Kyoka bravely stood her ground, but was nevertheless terrified at All For One's sheer malice as he volleyed several deadly attacks that just barely missed her, with one managing to tear her ear off. Despite the pain, Kyoka retorted that she had to face All For One for putting her friends Izuku and Yuga in so much distress before firing off her new special move, Heartbeat Surround Legato.

All For One took the attack head on and dismissed it as weak as he prepared to counterattack, gleeful at the thought of getting to kill another child. His arrogance was stopped short by the Quirk vestiges inside the weaker copy of his Quirk rebelling against him in response to Legato. Inspired by Kyoka's bravery, they held All For One back long enough for Hawks to finally shatter his mask, subsequently leading to Endeavor finally burning him to a crisp.

Kyoka's efforts proved instrumental in pushing All For One to the brink and make him trigger his last fail-safe by using a copy of Rewind to regenerate to full strength. While restored to his prime, he had also signed his death warrant and acknowledged Rewind would eventually kill him.

Mirio Togata
All For One, while unaware Mirio was at one point a candidate to be a One For All user, nevertheless came to blows with him in his vestige form during the battle at U.A. High School. While outwardly dismissing him as having nothing to offer, Mirio proved instrumental in disrupting the merger between himself and Tomura he believed had been completed flawlessly. Mirio's comment about Tomura wanting to destroy the world because he had no friends prompted his child self as "Tenko" to burst out and briefly wrest control away from All For One. The supervillain grew panicked upon discovering there was a part of Tomura he had failed to assimilate, since Mirio had unintentionally pulled at the thread that began unraveling his meticulous plan to steal One For All.

A short while later, Mirio threw All For One off-guard several times more, once by distracting him with a juvenile joke through "Full Moon Risin' Tonight", and then informing Izuku of Tomura's earlier outburst as Tenko, proving the merger between their wills wasn't as perfect as All For One was pretending. In his petty spite over being severely beaten by Izuku immediately after, he cursed Izuku and the other heroes for getting in his way, Mirio included.

Fumikage Tokoyami
In the beginning of the final war, All For One was confronted by Tokoyami as he supported Kyoka Jiro and Hawks during the battle over the ruins of Gunga Village. As the titular professional hero, and Endeavor, attempted to lead the former villain king away from the other heroes; particularly Izuku Midorya, as part of the combat strategy the hero coalition had concocted in preparation against Shigaraki's forces.

Fumikage would swoop in to give Jiro a chance to assist in the battle after AFO's provocations begat serious injuries on Enki Todoroki's part. Initially, All for One wrote both him and Kyoka as "side characters" in the manga he often read, Tokoyami would pay no mind to this and continue offering aid to Keigo during their bout. Despite his boasts however, the elder Shigaraki would soon come to regret his disregard of the two. As Tsukuyomi and Earphone Jack's running interference came in handy, much to his detriment. He particularly underestimated the destructive power of Tokoyami's quirk, as it was pivotal in crushing his mask after successive strikes by his mentors damaged it enough to be broken by the young hero completely.

Underneath all of his boasting and denunciation of the two students, AFO came to secretly fear the power behind Fumikage's Dark Shadow over time. After their second encounter where the latter had empowered his quirk using distaff darkness to enlarge itself. The demon king had the same premonition he received when the lot of them first shattered his life-support helmet as Light of Balder loomed over him. Citing that it is the truly strong ones of the bunch one needed to watch out for as the damage received caused All For One to regress even further.

Hitoshi Shinso
Hitoshi was one of those who joined the assault against All For One in Gunga, taming and controlling Gigantomachia in the process to face him.

Realizing this, All For One cursed Hitoshi and taunted him when he realized that due to his Quirk, the Aoyama family had managed to trick him. Sarcastically commenting that those kinds of tactics were his. Later he proceeded to attack the beast, managing to free it from Hitoshi's Brainwashing, only to be surprised when the beast turned on All For One of his own free will.
