All For One

, surname , is the overarching antagonist of the My Hero Academia manga and anime series. He was the founder and benefactor of the League of Villains.
Once Japan's most powerful villain, and All Might's arch-nemesis, his full identity is unknown. His ultimate goal was to steal One For All, the Quirk that originally belonged to his younger twin brother, the only Quirk that can oppose him. He was the mentor of Tomura Shigaraki, having spent the young villain's life shaping him into a successor, and a vessel for his power in a plan to eventually conquer the world as a self-proclaimed "demon lord".
He was imprisoned in Tartarus after his second defeat at All Might's hands until he escaped several months later, single-mindedly focused on destroying the ninth wielder of One For All, Izuku Midoriya, to complete his century-long plan.
==Appearance==
After being mortally injured by All Might years ago, All For One's face was entirely made up of scar tissue, extending from above his upper lip and covering his entire head and the back of his neck. As such, he had no visible nose, ears, hair, or eyes, though the outlines of his eye sockets were visible. All For One was blind but used an Infrared Quirk to "see," and he would sense the directions of vibrations in the area around him, similar to echolocation. There was a small hole in each palm of his hands, which is how he stole and transferred Quirks.
In the past, All For One was a towering man with a powerfully muscular physique, imposing features, short white hair, and faded red eyes that showed no sense of feeling. He usually wore a dark suit over a white shirt.
When All For One left his secret hideout during the Kamino Incident, he donned a navy blue, skull-like gas mask with angular tubes at the top, a wide collar-like life-support system around his neck with additional pipes connecting in the front and back, presumably to help him breathe.
For the start of the Final War, he wore a smoother skull mask with a much wider, sleeker collar. He also wore a patterned vest underneath his suit.
During his battle with Endeavor and Hawks, All For One used a reverse-engineered replica of the Quirk-Destroying Drug to restore his appearance to that of before his first fight with All Might, as well as stealing capes from the Heroes to cover himself up. As the damage inflicted upon him continued to stack and put his Rewind effect into overdrive, All For One continued to physically regress in age, from that of a young man, to a, temporarily glowing, young boy. The conclusion of the battle saw him finally regress back into an infant, and then a fetus, before an egg cell form as he vanished completely.

==Personality==
All For One was a subtle, sadistic, and malevolent man who liked to rule from the shadows and enjoyed himself at the expense of people before discarding them. In the past, All For One used his power to help people, but in exchange for their servitude. Once they could no longer follow his orders, All For One would callously abandon them, and his followers purged those who defied his will. Taking advantage of the chaotic era caused by the uprising of Quirks, All For One offered people anything they wanted as long as they followed him, including choice and power to those who had none, where he would take Quirks from those who didn't want them and gave Quirks to those who wished for strength, all as a means to gather numbers and conduct his schemes through other people. He masked his true intentions by claiming that he just wanted to help restore order and balance to society.
All For One exhibited extreme megalomania and even traits of an outright God complex, having compared himself to the Demon Lord he read about in comic books. He also relished his total power over Japan and saw himself as a higher being. All For One would steal the most powerful Quirks during his rise to power and crushed anyone who stood in his way. He also displayed signs of kleptomania, claiming that he couldn't resist stealing a powerful Quirk when the opportunity presented itself.
The only person All For One seemed to care for was his younger brother, Yoichi, as he was his only remaining family. However, All For One regarded Yoichi as his possession and was condescending towards him for his frail body, even kicking Yoichi for standing in his way. He was also exasperated by his brother's ideals of justice and attempts to stand in his way. All For One had a firm contempt for ideals of justice and morality, dismissing them as arbitrary beliefs of other people that shackle personal freedom. Like All Might yearned to become a symbol of justice, All For One sought to be an all-powerful evil, inspired by the comic books he read with Yoichi in their childhood. His ultimate goal was to use his power to thwart humanity's future and rule above everyone, as it fit with the "Demon Lord" character he envisioned himself as.
Ever since he was born, All For One was already quite selfish, arrogant, and had a discerning lack of empathy. Having been forced to survive in a chaotic era caused by the emergence of Quirks, he believed those who didn't help him deserved to perish, using the Quirk he took from his deceased mother to kill people while stealing their abilities. While his weak younger brother had nothing to offer him, All For One still kept Yoichi around as he felt as though he belonged to him. After being inspired by the Demon Lord in comic books, with how the fictional evil being reigned supreme and ruled through fear, he soon came to dream of a world that would submit to him, leading him down his evil path.
Even when his brother rebelled against him, All For One kept Yoichi alive and imprisoned him, hoping that if he gave his seemingly Quirkless brother a power of his own, he would join his side. When Yoichi chose to flee with Kudo and Bruce however, All For One proceeded to locate and kill him, having done so without any hesitation or remorse. According to Yoichi, All For One only saw people as playthings or as prizes to win, and in the end, even his own brother wasn't exempt from his possessive and dominant nature. Upon learning of One For All's creation, he became obsessed with claiming his brother's Quirk and would go on to pursue it for many decades, as while he didn't care for Yoichi personally, he wanted to regain his little brother and finally be able to possess him. In a twist of irony, All For One ended up creating the one Quirk that he couldn't steal, and along with it, generations of heroes who were sworn to fight and put a stop to him.
All For One was a patient mentor towards Tomura and often gave him constructive criticism and encouragement, even when the latter failed. Upon finding him all alone as a child, All For One took him in and gave him a room of his own while becoming his "Sensei"/"Master," going as far as to rename the young boy while giving him his surname, demonstrating a seemingly caring and even fatherly side. However, All For One only viewed Tomura as a mere vessel for himself, revealing that his reasons for raising him were purely for his own gain. All For One exploited Tomura's traumatic memories of his abusive father and groomed his rage so that he could use it as a tool to overwhelm the willpower of One For All and finally be able to steal the Quirk. This was made clear during the Paranormal Liberation War, where All For One took control of Tomura's body despite the latter's protests. In a twisted and selfish way, All For One was proud of Tomura's growth, knowing that he would serve him well as his new body, even claiming that Tomura would be "the next him."
All For One despised those who persistently defied him, especially the users of One For All. He loathed All Might in particular for ruining his syndicate and crippling him. He was also a firm believer in the hatred of the heart, having believed it to be a very strong source of power. When mentoring Tomura, All For One gave him the hands of his deceased relatives as a way for the negative feelings in his heart to remain close while also giving him a sense of comfort. When encountering the previous wills of One For All in the mental world, the vestige of All For One was not troubled when Tomura started to loathe him, stating that this hatred was only more fitting for the Symbol of Fear.
As much as he encouraged Tomura's hatred, All For One was also highly derisive and mocking towards his enemies as a means to get under their skin and/or cause them to drop their guard. His taunts and expertise in psychological warfare were enough to enrage even the strongest heroes, such as All Might and Endeavor. Even when outnumbered, All For One remained unshakably calm, willing to slaughter enemies with his tremendous power. He often regarded lesser opponents as fodder rather than actual threats, though he was ready to take an interest in their Quirks to see if they were worthy of taking for himself.
Due to his immense power and confidence, All For One had a calm and condescending demeanor, remaining confident even when thwarted and imprisoned. Later, the villain revealed to Dabi that he never depended on a single plan to achieve a goal and has multiple contingencies that he mapped out over his many years alive. He was not averse to acting pragmatically, such as choosing to have Tomura's remaining forces retreat during the Paranormal Liberation War, switching priorities from defeating the heroes to freeing himself from Tartarus. Thanks to a combination of Quirks, All For One was able to detect lies and hostility, with which he could preemptively eliminate traitors. Due to his long life, as well as his status and experience, he was well-informed about almost every significant figure among heroes and villains.
For his malevolent nature, All For One presented himself as polite, sympathetic, and generous towards his associates and underlings, often seeming amicable and fair-minded. However, this was only glib that All For One employed to subtly manipulate people into following his bidding, showing no concern for them once they were captured or outlived their usefulness. All For One admitted to Dabi that he sees people as nothing more than disposable tools - should they fail him, he shrugs and moves on to the next alternative, though he was willing to take enjoyment in when they received their comeuppance, be it from him or someone else. Even if his followers failed him, All For One admitted that it was worth seeing what entertainment they could bring before their downfall and would even tempt someone into helping him before sadistically watching them suffer, showing his twisted willingness to toy with people's lives while having a blatant disregard for whatever happens to them.
While All For One was completely selfish, he was willing to die for his ideals and would not spare any effort to ensure that his idea of a Symbol of Evil would continue even after his death. While he wanted to possess Tomura's body for his own ends, All For One didn't seem to mind if Tomura managed to kill him as long as he continued his legacy. Similarly, while it was not his intention at first, he had no problem sacrificing his own sense of self and allowing his consciousness to merge with Tomura's to become a new evil being entirely. Even so, after sacrificing his own body by activating the Rewind Drug, he became adamant about permanently taking over Tomura's body before his original self vanishes, reinforcing his self-centered ideals.
As a side effect of his own Quirk, All For One explained that he often suffered from nightmares where the people from whom he stole Quirks appeared in his dreams and hurled insults at him. Despite his remorseless personality, All For One admitted that such episodes sometimes left him feeling very discouraged. However, he scoffed at the idea of being able to feel guilt, as he believed it to be a trait of inferior humans. As further proof of his detachment, he repeatedly denied blame for any of his actions, instead laying the fault on his followers who only wanted to support him or who otherwise sided with his plans for their own reasons. He did this despite the evident fact that he had manipulated all parties involved into acting on his behalf with honey-laced promises while also taking advantage of their personal and emotional vulnerabilities to coerce them into enacting his will, persistently refusing to admit that he was to be held responsible, while at the same time, gloating about his results and his alleged power to achieve his goals, grinning with hypocritical delight. While it was initially believed that his followers carried out his orders out of loyalty to him, it's revealed that some obey him out of fear of reprisal, a strong rebuttal of All For One's belief that his supporters acted out of their own will and possible evidence of either a deluded sense of support to his ideals, or downright despicable lies to deflect blame.
It's implied that he required the hatred and will of Tomura to steal One For All successfully because All For One himself did not carry any hatred, or at least nowhere near as much as needed. Hawks questions why, after so many years of chasing down One For All, All For One would not deeply resent the users to that great of an extent, and theorizes that this was because something was missing in his soul, pointing out how he always smiled. This was supported by the fact that, no matter how cruel or sadistic his actions were, he never seemed to hold or exhibit any true malice or emotions. This apathy was further demonstrated during the Final War, as despite having been backed into a corner by the onslaught of heroes and at the threat of being rewound out of existence before he could finalize his plans, he still kept a smile on his face. All For One's complacent disposition could have been due to his selfishness, as he literally could not care about anything beyond himself enough to form the required attachments needed to create a powerful grudge or intense feeling of revenge. However, he was shown to be crying before killing Kudo, the second user of One For All, blaming the latter for taking his brother away from him, though he claimed these were only crocodile tears that were meant to cause confusion.
Although All For One grew a very strong contempt and hatred towards All Might for having permanently damaged his body and taking away his rule and status over Japan, he later admitted that he lost all interest in All Might and was solely focused on the current One For All wielder, Izuku Midoriya. It appears that All For One was so egomaniacal to the point where only those who persistently stood in his way and were strong enough to defy him warranted both his constant attention and hatred. He was so emotionally inclined towards his goals that he was either dismissive or manipulative towards everyone else, only seeing people as obstacles in his way or as pawns to manipulate for his own gain.
Despite how All For One was always perceived as calm and composed, a few instances agitated him to the point of becoming emotionally unstable, especially when his infallible belief that he was above all others was threatened. When someone challenged his authority, specifically those he deemed "insignificant," it was enough to rile him with anger and frustration. These included Star and Stripe after Tomura's attempt to steal New Order had failed, and people like Kyoka Jiro who refused to back down despite how significantly "weaker" they were in comparison to him. This was most emphasized through Kudo, who, despite being a "pebble" in his path that he could dispose of easily, was the one responsible for freeing his brother from his grasp and allowing One For All to exist. All For One eventually realized that Kudo was the one he truly hated the most, even years after the latter's death.
During the Final War, All For One's emotional instability worsened due to the repeated efforts and delays from the Heroes and students of U.A., the effects of the Rewind drug, and the side effects of melding with Tomura's mind. This caused All For One to become far more expressive with his emotions than before. For example, as All For One encountered All Might on his way to Tomura, he was unable to resist the hatred he felt towards his old archenemy and chose to confront him one last time, despite being on the clock due to the effects of Rewind, something his usual pragmatic self would have never done. All For One also became more spiteful as he intended to steal Fumikage Tokoyami's Quirk partially out of resentment for all the trouble he had caused him. His need to remain in control as the Demon Lord had magnified to the point where he outright denied anything that threatened this image. For instance, when All Might managed to delay him with his mechanized suit, All For One vehemently denied that All Might's plan to stall him worked, even though All For One actively chose to fight All Might instead of going after Tomura. Ironically, his plan to use Tomura's hatred to steal One For All would ultimately lead to his undoing and eventual demise.
In his final moments, All For One was left in such a vulnerable and emotional state that he finally admitted to himself his desire to become a Demon Lord was so that nobody would ever be able to forget him, since negative memories stick around in people's minds so strongly. All For One's own lack of strong motivation beyond rudimentary, basic hubris left him unprepared to deal with the strong emotions of not only Tomura, but all of the Heroes he had faced since launching the final phase of his plan to steal One For All. With all of his efforts come to nought as Katsuki applied the final bit of damage that caused him to vanish, he died crying and scared, unable to cope with having let emotions compromise him at the most critical juncture of his hundred year scheme and doomed to never reclaim his brother as his most prized "possession".
==Abilities==
Overall Abilities: All For One was one of Japan's most powerful villains. Thanks to the Life Force Quirk, All For One was virtually immortal and was active since the emergence of Quirks. He had collected numerous Quirks with an extensive range of applications and was able to combine them as he pleased. This longevity and the ability to steal any Quirk from his opponent made All For One nigh-impossible to defeat. The villain was willing to employ any means necessary to hurt his opponent before killing them. Following his final battle with Nana Shimura, All For One developed a fighting style that involved starting battles with powerful ranged attacks to wear down opponents before stealing their Quirks.
In his prime, All For One easily defeated powerful Pro Heroes, making himself appear unequaled and unstoppable. The only individuals that were able to effectively oppose the Symbol of Evil are the inheritors of One For All, a Quirk All For One himself inadvertently created, and the only Quirk he can't steal (though he tried to steal it from Daigoro Banjo and En, but failed both times). All For One sought each One For All user (excluding Hikage Shinomori), and easily killed them by overwhelming them with his barrage of Quirks. However, All For One could not steal One For All nor prevent any of the users from passing on the Quirk. Nevertheless, All For One remained unchallenged until the rise of All Might, who possessed the necessary strength to challenge All For One and the two opponents fought a bloody duel. Although All Might sustained crippling injuries, he succeeded in defeating All For One, forcing the villain to rely on a life support system.
Six years later, despite having lost his senses and being unable to recover from his injuries, All For One was far from weak. He single handedly overpowered Endeavor, Best Jeanist, Edgeshot, Mt. Lady, and Gran Torino with little effort, and was able to fight on par with All Might until the hero was exhausted out of his muscle form. With his ultimate Quirk combination and All Might's declining power, All For One nearly succeeded in killing All Might, but the latter summoned his willpower and used the last of his power to knock out the Symbol of Evil.
In the Final War, despite having been imprisoned for months, All For One's fighting skills showed very little decline. He fought top Pro Heroes Endeavor and Hawks, largely maintaining the upper hand while severely wounding the former. However, once the Flame Hero was revitalized, he overwhelmed and would've incinerated the villain had he not possessed the reverse-engineered Quirk-Destroying Drug.
As the effects of the Rewind drug accelerate, All For One's body rewound into a younger version of himself, making his abilities even more powerful than they ever were during his prime. All For One's power had increased even further in this more youthful state, allowing him to fend off Fumikage Tokoyami's "Light of Baldur" technique, which he previously struggled against. He was also able to overpower the combined all-out assault from Fumikage, Mt. Lady, Gigantomachia, and Inasa Yoarashi. The more injuries he received, the faster his Rewind effect became in responses, as he was able to instantly regenerate half of his body after it was vaporized from using his Impure Beam Quirk which brutalized Gigantomachia in his heavily armored casing and Dark Shadow in its Light of Baldur form.
*Immense Strength: All For One had tremendous amounts of incredible strength, easily trading blows with All Might, whose brawn was considered unrivaled. In his zenith, he was able to effortlessly overpower pre-Nomu Hood, though the latter was weakened from battling O'Clock and his allies.
*Immense Speed and Reflexes: All For One had incredible speed, as shown when he destroyed the Nomu factory, defeated the 4 Pro Heroes, and dealt significant damage to the surrounding area in a split second. He also has sharp reflexes, being fast enough to react to All Might's punches and casually dodge attacks from Edgeshot, who can transform faster than the speed of sound.
*Immense Durability: Despite being in a disheveled state with severe injuries, All For One possessed incredible durability. During his second battle with All Might, he, unlike the latter, never flinched or screamed from pain, proving that the Symbol of Evil was able to withstand the Symbol of Peace's destructive blows with monstrous resilience. Another testament of his sturdiness was when All For One survived All Might's United States of Smash, though was rendered unconscious afterward.
*Enhanced Senses: Due to All For One being blind, his hearing improved immensely, as he was able to perceive his surroundings by sound. He could also sense vibrations in the air. An example of this was displayed when All For One quickly dispelled a flame attack from Endeavor, who had arrived on the scene with Edgeshot. However, this ability does have its limits, which is shown when he is placed in Tartarus: the lack of sound and vibrations leaves him completely oblivious to his surroundings.
Genius Intellect: All For One possessed an extraordinary intellect, most likely due to his advanced age and life experience. He ruled Japan from the shadows for over a hundred years, with most of the public ignorant of his existence. He was well-informed about current affairs and significant figures among heroes and villains. He also possessed a vast knowledge of the Quirks he had stolen, which enabled him to use them effectively.
While condescending towards his opponents, All For One was an expert at observing his enemies and exploiting their flaws. Another terrifying aspect of All For One's intelligence was his ability to prey on people's insecurities. Aware that All Might still mourned his mentor, Nana Shimura, All For One used that to taunt the hero by insulting her and revealing that Tomura is Nana's grandson. Afterward, he exposed All Might's emaciated form to the public to demoralize them as well as humiliate the hero.
From observing All Might, All For One deduced that he no longer possessed One For All, and Izuku Midoriya inherited the Quirk. In the aftermath of the Kamino Incident, it was revealed that All For One anticipated the possibility of his second defeat at the hands of All Might. He knew if that were to happen, he would be unable to transfer his All For One Quirk onto Tomura as planned. To ensure the inheritance of his power was fulfilled, the Symbol of Evil, before resurfacing, had his Quirk replicated by his physician, Kyudai Garaki, leaving All For One with the copied variant and the Doctor with the original variant, which would then later be passed down to Tomura.
When attacking Tartarus with his army of High-End Nomu, All For One was able to overcome the prison's nearly impenetrable defenses through a coordinated attack from the outside (since his consciousness took control of Tomura's body) and inside (where his original body was housed). He successfully freed all the prisoners in Tartarus, including his original body. Given his inability to steal One For All and knowledge of Quirks being imprinted with the original user's consciousness, it has been discussed that All For One primarily grooms Tomura's negative emotions so the former's will inside of the All For One Quirk can more easily inhabit Tomura's modified chassis, all in a final attempt for the original Symbol of Evil to acquire One For All.
Indomitable Will: Befitting his epithet, the Symbol of Evil, All For One possessed a malefic volition so resolute that he could quickly amass hordes of followers in his long life through sheer influence. Within and outside the battlefield, All For One was unfazed by unforeseen spectacles that would leave him otherwise intimidated or unhinged, and he commonly maintains his complacent attitude even when he seemed to be at a disadvantage. His presence was shown to be so malicious and dark, Izuku, Tenya Ida, Momo Yaoyorozu, Shoto Todoroki, and Eijiro Kirishima were utterly paralyzed with fear, despite the quintet previously experiencing life-or-death situations and encountering lethal villains. All For One's will was also significant enough for his original Quirk to overwhelm Tomura Shigaraki's willpower and possess the young villain like a puppet. This was convenient as All For One planned to transfer his consciousness into Tomura, intending to become a more powerful being.
However, in spite of having his ambitions thwarted time and again by users of One For All and the circumstance of All Might destroying his body and permanently crippling him, his hatred, if any, wasn't strong enough to allow him to override the collective willpower of One For All's users. Even disregarding the physical requirements to take One For All into himself, he seemed to lack the emotional resolve to overpower the wills of the spirits in One For All. This indicated that while his will is unyielding when it comes to resisting things that might change him personally (his sense of self/personality), he didn't care enough about anyone or anything to have an emotional investment to strengthen his will. Tellingly, when Tomura was in a negative state and consumed by rage, All For One was able to take control of his protegee's body, as anger causes people to become unstable and forget themselves.
Despite All For One's tremendously strong willpower, it ultimately lost to Tomura, who hid his origin deep within their vestige as a means of winning back control over his body and the All For One Quirk. Later, All For One was unable to warp Tomura to his location, as the latter's terrifying willpower far exceeded his own.
===Quirks===
: All For One's Quirk allows him to steal other people's Quirks, leaving them Quirkless, and wield the Quirks as his own. All For One can also redistribute his stolen Quirks to other people.
His multiple Quirks grant him a very wide variety of options in combat, and he can combine his stolen Quirks to create compound attacks with devastating effects. However, he cannot steal the original users' Quirk proficiency and is therefore limited by his own skill with his stolen powers. Because of this, he prefers to steal Quirks that rely more on raw power, rather than ones that take practice and experience to master. In order to steal a Quirk, he also must physically touch the user's body, as touching something produced by a Quirk, such as the flames of a fire user, would not suffice.
While he can steal any Quirk, All For One's body cannot properly contain Quirks of newer generations, which is the reason why he sought Dr. Garaki's medical research. He also mentions having frequent nightmares where the consciousnesses of the people he stole Quirks from appear before him. To top it off, All For One's permanently injured body puts a limit on how many Quirks he can take and use in succession, making him far weaker than he was in his prime.
Shortly before the Kamino Incident, his Quirk was duplicated by Doctor Garaki and the original version of it was given to Tomura, while All For One kept the copied version. A conscious vestige of All For One remains within the original Quirk and has the capabilities of overriding Tomura's will and taking control of his body. It is revealed that the vestige of All For One and the real All For One can work in tandem with one another, as seen when a possessed Tomura attacked Tartarus and gave time for All For One to act and free himself along with all the other prisoners. The copied version of All For One doesn't give him as much command however, meaning that vestiges from stolen Quirks can resist the user from within.
All For One has stolen a wide variety of Quirks with his ability, including:
*: This Quirk generates drill-like bone structures around All For One's body. All For One stole this Quirk from his mother after he was born and is the first Quirk stolen by him overall.
*: All For One stole this Quirk from Ragdoll. With this Quirk, he can observe and monitor up to a hundred people at a time, including their location and weak points.
*: All For One can produce a black liquid that acts as a portal, similar in nature to Kurogiri's Warp Gate. He can use this Quirk on a large scale, producing multiple black liquid portals that transport dozens of Nomu to the League of Villains' hideout, and later the entirety of the Paranormal Liberation Front for the final battle. This Quirk, however, has many limitations: it's not a coordinate-based warping and can only warp things to and from his location. It also has a limited range and it only works if it's used on someone with whom he has a close relationship.
*: All For One releases an air shockwave from his arms. This Quirk is further strengthened by its combined usage with Springlike Limbs and several other power-up Quirks.
*: This Quirk allows All For One to coil his muscles in order to enhance his physical strength, and can also be used to augment other Quirks, like Air Cannon.
*: All For One transforms his fingers into black tendrils that have red prominent cracked lines that extend from the his fingers, although they can also emerge from other parts of the body such as the spine. These appendages can easily pierce bodies, however, the user may choose whether to wound the target or not, as seen when All For One used it with Forced Quirk Activation, without harming the target.
*: All For One can activate a target's Quirk against their will, whether they are conscious or not. All For One has used this Quirk in combination with Rivet Stab.
*: This Quirk seemingly enables All For One to completely reflect the impact of an attack back to the attacker.
*: This Quirk seemingly multiplies the number of All For One's arms.
*: This Quirk seemingly enlarges All For One's arm.
*: This Quirk possibly generates rivet-like growths on All For One's arm.
*: This Quirk seemingly increases the amount of kinetic energy All For One creates and releases. All For One has four copies of this Quirk.
*: The Quirk grants All For One a boost in physical strength. All For One has three copies of this Quirk.
*: This Quirk allows All For One to sense his surroundings using infrared senses. He uses this Quirk to compensate for his blindness. However, the amount that he is able to sense is very limited.
*: This Quirk was given to him by Doctor Garaki, and has allowed him to possess supernatural longevity in lifespan.
*: All For One can disrupt radio waves and cause communicators to malfunction.
*: This Quirk allows All For One to generate a wall of flames to act as defense.
*: This Quirk grants All For One a pair of bright red, feathery wings on his back, albeit only in its stub form due to the Quirk already being damaged. All For One stole this Quirk from Hawks.
*: This Quirk allows All For One to unleash a powerful beam of light, which in conjunction with his power-boosting Quirks, turns it into a devastating explosion. It's strong enough to severely damage Gigantomachia and Dark Shadow in its Light of Baldur form with a single shot. It is one of All For One's most powerful Quirks. The only major drawback of this Quirk is that All For One's body cannot withstand the power of the blasts as it maims his own arm in the process, and as a result, slowing down the reversed-engineered Rewind drug regeneration.
*: This Quirk allows All For One to release an array of dark balls.
*: This Quirk allows All For One to expel all the blood from within his body and then retracts it back into his body.
*: This Quirk allows All For One to change his blood type. He used this Quirk in the past to leave no traces of himself behind.
*: This Quirk allows the user to paralyze someone when they ingest their blood and based on the blood type, can paralyze for extended periods of time. All For One stole this Quirk from Stain.
*Unnamed Luminescence Quirk: This Quirk allows All For One to illuminate himself. All For One stole this Quirk from the grown-up Luminescent Baby.
*Unnamed Telekinesis Quirk: This Quirk allows All For One the ability to levitate objects with his hand. He used it to levitate his medical device once freed from Tartarus.
*Unnamed Mind Control Quirk: This Quirk allows All For One to control a person's actions by touching their head. He used it on a Tartarus guard to fly an emergency plane and escape the prison.
*Unnamed Lie Detector Quirk: This Quirk allows All For One to sense whether a person is lying or if they possess any semblance of ill will. The Quirk got stronger through the mixing of various other Quirks throughout the years. The Quirk was stolen from Naomasa Tsukauchi's ancestor.
*Unnamed Levitation Quirk: This Quirk allows All For One to levitate in the air.
*Unnamed Razor Blade Quirk: This Quirk allows All For One to create crescent shaped razor blades.
*Unnamed Ooze Quirk: This Quirk allows All For One to generate a muck-looking substance which can cover and dissolve an area.
*Unnamed Mouth Quirk: This Quirk allows All For One to morph the flesh on his hand into a mouth which can be shot out to attack. It has enough strength to bite through flesh. He can alter their size by using his entire hand, making them range from the size of a small mouth to the size of an enormous structure. Additionally, he has the ability to sprout appendages from his back that resemble a long mouth and are strong enough to tear into a whole body.
*Unnamed Vibration Detection Quirk: This Quirk allows All For One to enhance his senses about his surroundings. He uses it along with Infrared to compensate for his lack of vision and hearing, while at the same time giving him incredible awareness of the world around him.
*Unnamed Glue Quirk: This Quirk allows All For One to generate a glue-like substance which can be used to instantly joint broken pieces together. He used it along with Rivet Stab to try and repair his broken mask.
*Unnamed Spatial Distortion Quirk: This Quirk allows All For One to manipulate the space around him at a range, similar to the Quirk of the Nomu Robot. He uses it to seemingly kill Hawks, only for it be an illusion. He has previously used it to kill his brother and claim his left hand.
*Unnamed Body Appendages Quirk: This Quirk allows All For One to grow appendages from his back in the shape of wings that can serve to expand the usage of his Black Lightning Quirk.
*Unnamed Black Lightning Quirk: This Quirk allows All For One to shoot black lightning bolts from his body. He uses this in combination with his Body Appendages Quirk.
*Unnamed Repulsion Quirk: This Quirk allows All For One to generate repulsion rings that let him propel himself through an allegedly repulsive force, gaining a rapid increase in speed.
*Unnamed Fangs Quirk: This mutant Quirk gives the user a fanged jawbone. All For One took this from someone in the past as a favor to make him one of his loyal servants.
*Unnamed Mutant Quirks: All For One stole a variety of mutant Quirks in his quest to force people to submit to his will.
*Unnamed Hardening Quirk: This Quirk allows All For One to somewhat harden his skin exceptionally. He stole this Quirk from a fighter in the Underground Masquerade.
===Former Quirks===
Quirks obtained via All For One and then passed onto others:
*Power Stockpiling: An unnamed Quirk which allowed All For One to stockpile power. He gave it to his younger brother to try and force him to his side, causing it to merge with his Quirk and create the Quirk One For All.
*: This Quirk allows the user to project twinkling laser beams from their navel. This Quirk was given to Yuga Aoyama.
*: This Quirk allows the user to shapeshift their arms. This Quirk was given to Hood to try and make him a better fighter.
*: This Quirk allows the user to grow mole-like claws from their fingers, as well as spines on their back, to dig through the earth. This Quirk was given to Gigantomachia for the purpose of hiding underground.
*: This Quirk allows the user to stimulate their brain's perception of information, granting them hyper speed, reflexes, and an improvement to their healing factor. This Quirk was stolen from O'Clock and given to Number 6.
*: This Quirk allows the user to augment the power of their muscles, changing their appearance. This Quirk was given to Wolfram to assist in his incident.
*: This Quirk is capable of allowing the user to levitate and walk in mid-air. This Quirk was given to Lady Nagant as payment to capture Izuku.
*Unnamed Self-Destruct Quirk: This Quirk makes the user self-destruct in a big explosion. This Quirk was secretly given to Lady Nagant in case she failed in her mission.
*: This Quirk bulks the users entire body, greatly increasing their strength and body size. This Quirk was given to Spinner to grant him extra power in the Final War.
*: This Quirk covers the user with sharp scale-like armor, granting them increased strength and defense. This Quirk was also given to Spinner at the same time as Body Bulk.
*Several unnamed Quirks: All For One transferred several Quirks to fighters in the Underground Masquerade including: an electricity-based power, beast-like traits, making the user turtle-like with a spiked shell and cannon on their back, granting the user wings in place of arms, giving the user arm-scythes, making the user wolf-like, a strength enhancer, and a reptilian transformation. He also transferred a variety of power-up Quirks to the Near High-End Nomu to buff them up during the Final War..
It's also possible that he possessed some, if not all, of the Quirks possessed by his Nomu, as well as Gigantomachia's additional Quirks. It is also possible that he still retains some, if not all, of the Quirks he's transferred away as originals or duplicates.
===Ultimate Moves===
*: All For One utilizes the strongest combination of Quirks that he currently holds inside his body to greatly enhance his right arm, combining Springlike Limbs, Multiplier, Hypertrophy, Rivet, Air Walk, and Spearlike Bones, as well as four Kinetic Booster Quirks and three Strength Enhancer Quirks. This combination of Quirks is what All For One attempted to use in order to kill All Might. Impact Recoil was later added to this combination to better his chances of defeating All Might.
*: All For One summons every single Quirk he has ever stolen into one powerful attack. He uses this move during the Final War in an effort to kill Katsuki Bakugo and succeed in his goal of reaching Tomura all at once.
===Stats===
==Equipment==
*Breathing Mask: All For One suffered serious damage in his battle against All Might and now has trouble breathing. He wore this mask to compensate. After escaping from Tartarus, All For One used an upgraded version of this mask after the previous one was destroyed by All Might. Both were created by Kyudai Garaki.
*Rewind Drug: Created by Kyudai based on the sample of the Shie Hassaikai's Quirk-Destroying Drug, this version focuses on the original effect of Rewind and restores All For One's body back to his prime state. However, it could only be used once as a last resort as it eventually rewinded All For One out of existence.

==Trivia==
*All For One's surname contained the kanji for , and .
*All For One's rankings in the Popularity Polls are as following:
**Ranked 49th in the second Popularity Poll.
**Ranked 69th in the fourth Popularity Poll.
**Ranked 40th in the fifth Popularity Poll.
*All For One's black, ornate mask and life-support system were possibly inspired by the character of , the iconic antagonist of the first trilogy and recurring element of the franchise as a whole.
**While the black skull-like shape comes from the Batman villain .
**He also resembled the Superman villain , one of the first recurring villains in comics with a genius intellect and the ability to transfer his mind into other beings, as he does when his Quirk was transferred into Tomura.
**His status as All Might's arch nemesis, genius intellect, baldness, and wearing a suit also made him similar to , Superman's arch enemy.
*All For One was one of the oldest known individuals in the series, predating generations of users of One For All and their associates, such as the elderly Gran Torino, though it's unclear whether or not he was older than Doctor Garaki.
*All For One and Tomura have the most Quirks in the series, however between Tomura losing several Quirks after they were destroyed by New Order, and All For One transferring some of his to others, it's unknown who had the most.
*All For One was a dark parallel to All Might.
**All For One had once been Japan's worst villain, just like All Might was Japan's greatest hero. This was further emphasized by All For One bearing the epithet "Symbol of Evil", contrasting with All Might's epithet "Symbol of Peace".
**Both also passed on their respective Quirks All For One and One For All to their successors, with the intention of them improving their usage and taking up their former titles as the "Symbol of Peace" and "Symbol of Evil", though All For One still has a copy of his Quirk.
*All For One's relationship with Tomura was a dark mirror to All Might's relationship with Izuku. Like All Might, All For One believed that Tomura will not only become a great successor of the League of Villains, but a great villain in general. He also acknowledged Tomura's childish nature, leaving room for him to teach him how to become a villain. He also showed a caring side for him, as he assured that Tomura would always be able to learn from his failures.
**Because of this, Tomura looked up to All For One as his ideal mentor and inspirational figure, like how Izuku looks up to All Might.
**Despite his childlike behavior, it's implied that All For One admired Tomura's personality in an odd way, similar to All Might's own admiration of Izuku's personality. When he defeated Best Jeanist, he refused to take away his Quirk, as he believed that "it wouldn't fit Tomura's personality".
**The biggest difference between the two is that while All Might truly wants Izuku Midoriya to be his successor, All For One had selfish reasons for grooming Tomura as his successor. Over the decades, All For One found it increasingly burdensome to store Quirks due to the Quirk Singularity and his body was extremely damaged following his first battle with All Might, and thus needed a more superior and healthy body to properly contain advanced Quirks and regain his strength. That was the reason he had Tomura undergo the body augmentation surgery and transplanted the original All For One Quirk onto him, so that he could take over the younger villain's body. The other reason was that Tomura's hatred would allow All For One to steal One For All, which would have otherwise been impossible.
**Ironically, while Tomura grew to be the strongest villain in the world with strength exceeding even that of his master, All For One became more reckless and insecure upon using the Rewind Drug, causing his behavior to resemble Tomura's in the latter's early stages.
*While he was imprisoned in Tartarus, his prisoner number was 1541.
*All For One was the first known villain to name himself after his Quirk: the latters are Kai Chisaki and Hari Kurono, and the thirds are Chojuro Kon and Kiruka Hasaki.
*All For One's background and history with Yoichi seem to have been inspired by the mythological story of the founders of Rome, , with the two fulfilling these respective roles as brothers and the "founders" of superhuman society, analogous with the founding of the famous city. While no wolf or shepherd came to care for the twins like in the story, All For One did suck the remaining Quirk and nutrients from his mother's fresh corpse by a river as a reference to the famous portion where the Roman twins suckled from a she-wolf after being rescued from the Tiber. Romulus eventually wound up ruling Rome as its first king after murdering Remus (in some versions of the story at least). This matches the events where All For One kills Yoichi and goes on to reign over the chaotic century of super-powered society that formed, only forced to retreat into the shadows after his first defeat at All Might's hands.
**All For One's own short-cropped hair seems similar to the initial Roman emperor, Augustus, compared to the more stylish/shaggy hairstyles Horikoshi normally draws for his characters.
==Quotes==
*(To Yoichi) "Remember what that comic book said? "One for all" and "all for one". Words to live by. That hero had to hide his identity and battle on in solitude... while everyone paid tribute to the wicked demon lord out of fear. Just as you were inspired, I now want a world that exists for my sake and mine alone. I've found my own dream!"
*(In regards to Yoichi and One For All) "My crocodile tears served to cause confusion and dismay. All that I loathed... and everything I coveted... I had manipulated... and corrupted... to make it all my own. Yet... you never behave as I wish. I only want... to make you mine! I hunt... and pursue... yet you slip through my grasp."
*(To Nana) "Thank you truly, for this amusing farce."
*(To Doctor Ujiko, in regards to Tomura) "I know that boy will rise to the occasion. He was born twisted. So enjoy it while you can, All Might... This transient peace of yours!"
*(To Tomura about the League of Villains and Katsuki Bakugo) "You've failed again, Tomura. But you mustn't lose heart. There will be more chances to set things right. That's why I've brought along your little band. And the boy... because you determined that he is an important pawn. So go and try again. That's what I'm here to help you to do. It's... all... for you."
*(All For One to All Might, saying his slogan) "I don't think so, because I am here."
*(To Tomura) "Heart is power, and the more fiercely he embraces that source in his heart, the more my consciousness takes hold in our little symbiotic relationship. Never let that hatred die, Tomura."
*(To himself) "Why do they assume tomorrow will come for them? No, I won't grant them a moment's rest. Because it's my turn now, and my turn will never end."
*(To the prisoners of Tartarus) "If it's freedom you desire, then submit to me, my brethren. And bear witness, by my side. This impending void era will give rise to a more perfect demon lord. This will be the story of how I became the greatest demon lord of all!"
*(To Endeavor and Hawks) "My side was entirely on defense during the last great battle. In fact, I hear you and yours kept them from accomplishing much of anything. This time? Not so much. Heroes are those who defend, while Villains violate. Behold, as we plunge headlong toward our dreams!!"
*(To Katsuki Bakugo) "'I must save all my remaining strength to succeed in that transfer.' Such was my thinking, but... no, enough of this. Killing you, reaching my goal, executing the transfer... All are one and the same."
