This article is about the Quirk. For the Quirk's original user, see All For One.

All For One (オール・フォー・ワン Ōru Fō Wan?) is the Quirk used by All For One, before being transferred to his successor, Tomura Shigaraki, while keeping a duplicate. A weaker version of the Quirk was also used by Nine.

Description[]

All For One allows the user to steal Quirks from anyone they touch for personal use or transfer the stolen Quirks to anyone. It also allows the user to wield several Quirks simultaneously. Giving and taking away Quirks is done through touch, through a hole in the palm of the user's hand, once it receives contact.

A victim whose Quirk has been stolen becomes Quirkless and loses any abnormal features if the powers are Mutant-types. Interestingly, even if the user holds Mutant-type Quirks, the subsequent features do not permanently manifest on the user's body, and they can summon the mutant features at will. Additionally, when a Quirk is stolen, the victim becomes disoriented and immobile for a short time. Meanwhile, Quirkless people who receive a Quirk through All For One can manifest all its attributes. On another note, if a Quirkless person receives a Mutant-type Quirk, there is a chance that the transformation will manifest differently than it did with the original user.

Rarely a Quirk granted by this ability can blend with the recipient's original Quirk, creating an entirely new power, as shown with One For All.[1] In addition, it is also possible for the Quirks stored within All For One to be combined with other Quirks to boost their efficiency, as demonstrated with All For One's lie detection Quirk that he stole when Quirks first began.[2]

All For One can be used to combine several Quirks to create devastating techniques, which would typically not be possible with the usage of only one Quirk.[3] Furthermore, it can also be used to help restrict a Quirk's drawbacks and weaknesses through the usage of other Quirks, allowing the user to easily handle multiple powers without facing repercussions to their body.

All For One attempts to take control of Tomura

All For One's users, past and present, fighting for control.

All For One's first user intended to have Tomura inherit his Quirk, implying that transferring All For One itself to another person is possible.[4] This was evinced to have already been accomplished, as All For One, before being sent to Tartarus, had Doctor Kyudai Garaki extract his power from his body, and duplicated, with the original being kept on standby to be passed on to Tomura. At the same time, the Symbol of Evil retained the copied version of his original Quirk.[5] It has been shown that the recipient of the All For One Quirk itself can access the Quirks that the previous user possessed due to the said powers becoming applications of All For One, rather than extra Quirks.[6]

Another facet of receiving this power is having a mental link with the previous user, whose psyche was imprinted onto the All For One Quirk. As a result, Tomura exhibits some of his master's personality traits and can meet with a vestige of All For One within his own mind.[7][8] This is similar to how the wills of the One For All users are integrated into One For All itself, which has evolved to where Izuku Midoriya can communicate with the previous inheritors of the said power. It was soon revealed that both cases are due to the familiar spectacle that Quirks, much like organs during organ transplants, retain the consciousness of their donor, whose power was granted to the recipient.[9]

All For One seems to grant access to an unidentified mental realm contained within the Quirk similar to its counterpart Quirk, One For All, as shown when Tomura tries to steal One For All from Izuku. When this happened, the mental realms of both Quirks became connected temporarily, and the current users and the stored consciousness of previous users were shown inhabiting the same mental realm. Furthermore, since the Quirks are counterparts to each other, the vestiges of the earlier users resonate with the other Quirk and can peer into each other's inner workings, as shown when Tomura and All For One can see the vestiges of the previous users of One For All alongside Izuku during their subsequent encounter.[10]

Weaknesses[]

There are some limitations to the Quirk. Only some recipients of a Quirk acquired from All For One can handle the strain of gaining them. Subsequently, they may become mindless dolls who cannot speak or think for themselves. Being Quirk-empowered before receiving a Quirk from All For One is a factor that allows a person's body to withstand the Quirk-bestowal process. This spectacle was evident when Yoichi Shigaraki, Wolfram, and Lady Nagant were not put into brain-dead states upon being endowed with a Quirk by All For One due to already owning their respective Quirks.[1][11] Despite this, being Quirk-empowered does not guarantee a person can withstand the strain, as Spinner's mind became more unhinged after having received two extra Quirks from All For One, causing him to behave more irrationally and violently.[12] However, even if a person can hold their new Quirk, there is still a chance their body will not be able to handle its power correctly. This incompatibility is first demonstrated by Yuga Aoyama, who cannot use his Navel Laser Quirk without a special belt to assist him and even risks damaging his internal organs if he uses the Quirk for too long.[13]

The effectiveness of the Quirks that are stolen by All For One depends on his abilities. He stated that he did not want to steal Best Jeanist's Fiber Master, as it required too much training and experience to master truly; this implies that he prefers to steal Quirks with straightforward abilities.[14]

Nine tries to steal One For All

Nine attempting, and failing, to steal One For All.

All For One cannot steal One For All from its wielder, as that Quirk, by its very nature, can only be passed on if the present wielder wills it.[1] Thus, wielders of One For All can act as a natural counter against All For One's ability to steal other Quirks. However, he overcame this limitation in the past against previous wielders of One For All due to the sheer number of Quirks he possessed. Furthermore, Kyudai performed various experiments on the body of Tomura so that the latter could be capable of stealing One For All, a feat All For One himself couldn't accomplish. It was eventually revealed that someone with strong negative emotions can override One For All's anti-theft properties because it eats away at the potential inheritor's will. The vestiges of the previous One For All users surmised that All For One has been grooming Tomura's body and hatred to override One For All's will and finally steal it in that manner.[15] This also means that the elder Shigaraki didn't have enough hatred to steal One For All on his own.

It's been discussed by Kyudai that, over time, the large number of accumulated Quirks within All For One was becoming dangerous to the user himself. While All For One could allow the user to control any number of Quirks safely, there is a limit to how much the user can control without adversely affecting them, like the Nomu. Kyudai went on to state that if the "memory" (the amount of power of a Quirk) exceeds the "hardware" (the body of the Quirk user), then it will cause serious problems.[16] This is somewhat similar to One for All, which causes a severe burden on the user's body and can shorten their lifespan if they already possess a Quirk when receiving it due to the burden of having multiple Quirks.[17]

Tomura's body begins to fail

Tomura's incomplete body unable to properly handle All For One.

The body strain drawback of this Quirk was displayed during the Paranormal Liberation War when Tomura's body began to suddenly tear apart despite having Super Regeneration, which activated shortly afterward. Tomura was intended to awaken with his newly enhanced body within four months but was forced out of stasis early due to Mirko shattering his capsule, leaving him at 75% of his intended strength. Due to this premature emergence and insufficient power, Tomura's body couldn't keep up with the power of All For One and the multitude of Quirks stored within it.[18] Furthermore, due to the multiple different Quirks stored within All For One and have changed over the years, Tomura's body is unable to handle all these Quirks properly and has experienced the effects of the Quirk Singularity Theory, which results in his body growing hundreds of hands and fingers uncontrollably.[19][20]

Quirks are tied to their user's body and have been stated to be a function of the user's physiology; much like an organ or limb, injuries or adverse health conditions will limit a user's Quirk or their ability to use it. This drawback is even more pronounced with All For One, as the ability to use stolen Quirks, along with how many Quirks can be stolen, is directly connected to the health and strength of the user's body, the user's ability to steal Quirks and use them is drastically diminished if they become injured or disabled. After his first battle against All Might, All For One's permanent, life-threatening injuries drastically reduced his power and output with his Quirk, forcing him to come up with a way to either heal himself or strengthen and take a new body to recover and surpass his previous limits.

A hostile Quirk going berserk in the vestige world.

All For One can only give and take Quirks from others; it does not allow the user to destroy the ones they hold, even if they threaten the user's health. After stealing New Order from Star and Stripe, the hero placed a rule on her Quirk, which stated that it would revolt against other Quirks, allowing New Order to severely weaken Tomura's body and destroy many of his Quirks from within.[21] The only way for an All For One user to rid themselves of a self-destructive Quirk is for them to transfer it to someone else, as demonstrated by "Tomura's" failed attempt to do so with New Order. Another possibility would be for the user to gain a Quirk that could heal or negate another Quirk's damaging effects, although this was impossible with New Order as the rule set upon it prevented it from coexisting with other Quirks.

Another critical weakness of All For One for an inheritor of the original Quirk variant is the threat of the previous wielder's will taking over the body and controlling the current user, as is the case for Tomura being taken over by All For One. As described by the vestigial will of All For One contained within the Quirk, negative emotions such as hatred and anger would allow his consciousness to take over the body of its current wielder, as well as shape the body into a whole new being, that is a fusion of the two minds.[22] However, should the new wielder possess the willpower necessary, they can replace the original vestige entirely if said vestigial will sustains enough damage, as demonstrated by Tomura after All For One was defeated by Izuku and a group of other heroes.

With Nine's lower-tier variation of the Quirk, he could only steal up to 8 other Quirks. In his attempt to steal One For All from Izuku Midoriya, Nine could not do so, which he believed was due to his storage limit (the Quirk's anti-theft properties). It is unknown if Nine's version allowed him to transfer Quirks to other people, as he was never seen nor mentioned to have done so. Moreover, the power of All For One put further strain on his body and caused the cellular degeneration from his Weather Manipulation Quirk to worsen. This drawback is the reason why Nine attempted to steal the Cell Activation Quirk of Katsuma Shimano so that he can rejuvenate his lost cells and continue using his various Quirks without limit.[23]

With All For One's duplicate of his own Quirk, it is revealed during the Final War that the copied version gives him less power over his stolen Quirks than the original. This inferior duplicate has caused some of the vestiges of people he's stolen Quirks from to rebel against him and hinder him in battle.[24] Much later, after using the Rewind Drug and taking brutal damage, All For One loses control of his Quirks as a result of his emotions overwhelming him.[25]

Since All For One's Quirk Factor resides in the user's hands, they would be unable to use it should they lose said limbs unless they possess a Quirk that can regenerate and regrow them. Likewise, for All For One to steal another Quirk, the user must physically touch the target, not the unleashed Quirk. For example, they cannot steal a flame-based Quirk by touching the flames released from a person.

If a Quirk Factor is significantly damaged when stolen from a user, All For One will only obtain the Quirk in its current weakened state, as shown when he stole Fierce Wings from Hawks, which only manifested in their small stub form.[26]

Usage[]

All For One[]

The man who would call himself "All For One", manifested his eponymous Quirk mere moments after he was born. It is implied that the All For One Quirk manifested even before its user was born, with the fetus being able to steal most of the nutrients for himself and draining his mother's life force. As a newborn, he instinctively stole his mother's Meta Ability, Spearlike Bones, demonstrating his innate knowledge of stealing and giving Quirks. He initially used the Quirk to kill and take from whoever stood in his way, believing all was for him. He would then wield his Quirk to dominate Japanese society since over a century ago, using his Quirk to take away unwanted Quirks and give them to those who needed them in exchange for favors. Eventually, All For One's user would amass a large following of loyal subordinates who fulfilled his wishes.

Later, this man would use All For One to empower genetically engineered creatures known as "Nomu" to assist Tomura and the League of Villains with the achievement of their goals. The Nomus' creator, Kyudai Garaki, explained that artificially transplanting Quirks, most of which he was able to replicate,[27] into a person's body requires complex surgery and takes at least three months to integrate into the chassis fully. Still, it's more difficult without All For One.[28] This vindication postulates that All For One's ability to transfer Quirks onto people made the Nomu production process much more manageable.

All For One using multiple Quirks

Ultimate combination of Quirks.

For combat, All For One's user prefers to combine many of the Quirks he has collected throughout his life to maximize their power and effectiveness, often to catastrophic levels. Since this man has no qualms with killing, he doesn't hold back in fights and will even target defenseless people, using them as a distraction to his advantage. Despite his severe and debilitating injuries, the Symbol of Evil was still an incredibly fearsome adversary, using his many Quirks to unleash destruction onto his surroundings. He also used an Infrared Quirk to sense other people and compensate for his blindness.

It's been suggested by All Might that All For One was used to obtain a Quirk that grants agelessness, explaining how its user is still alive to this day. This longevity would later be confirmed by Kyudai, who replicated his own Life Force Quirk, gave the original to All For One, and kept a copy. All For One was also able to circumvent this Quirk's dampening effect on physical mobility by using other Quirks.

All For One can also implant more than one Quirk within a person without them noticing, allowing him to sabotage them and turn them into living weapons secretly. Knowing that Lady Nagant was liable to turn on him while fighting Deku, the villain secretly gave her a Self-Destruct Quirk that exploded from within her after she was swayed by the young man's heroic spirit, which almost succeeded in killing her.[29] This made the Heroes highly wary while dealing with adversaries sent by All For One, as they feared that other assailants might have been rigged to explode this way as well.[30][31]

As All For One gained complete power over Japan, he plans to do the same with the whole world by causing total devastation, which would cause currencies around the world to lose their value, creating a worldwide catastrophe similar to the Great Depression or the chaotic uprising of Quirks. His ultimate goal is to make Quirks the sole factor in people's lives to bring about sustenance, water, and power. Because of this, people would have to rely on All For One for his vast myriad of Quirks and his ability to give and take them to solve all their needs, thus granting him complete control over the world.

Sometime before the Kamino Incident, All For One had his Quirk duplicated, keeping the copied version for himself while the original was preserved until it was finally transferred to Tomura.[5] During the Final War however, it is revealed that the duplicated version of the Quirk does not give All For One as many commands over his stolen Quirks as the original, causing some of the vestiges of whom he's stolen Quirks from to rebel against him.[24]

All For One has stated that if he can get Tomura to absorb his duplicate of the Quirk, then he will be able to take complete control over his body and permanently suppress his personality.[32] Before his disappearance, All For One comments that the vestige within is likely suppressed after Tomura regains control and still holds one final tactic that wasn't used before being usurped.

Nine[]

Nine donated his body to Kyudai Garaki of the League of Villains for experimentation so that he could become more powerful. During the process, Nine was implanted with the DNA of All For One, and since his body was compatible with the latter's Quirk Factor, he obtained the same power to steal Quirks from other people. However, his variant was much weaker compared to the original user, as Nine was only capable of stealing eight other Quirks, and it's unclear whether he was capable of giving Quirks to others.[23]

Nine used All For One to gain more power by targeting the Quirks of Pro Heroes, choosing to steal and use ones of particular natures, allowing him to attack and defend from short and long-range distances. He also acquired a Scanning Quirk that allowed him to view other people's Quirks and measure their power, which gave him more insight into different Quirks and allowed him to identify and pursue the ones he wanted more quickly.

Tomura Shigaraki[]

Foreseeing his defeat at the hands of All Might, All For One had his Quirk duplicated, keeping the duplicate for himself while his ally, Kyudai Garaki, preserved the original, intending to have it transferred to his disciple, Tomura Shigaraki. Kyudai would then perform a long and complex operation to transfer All For One to Tomura.[5] After the procedure was complete, Tomura was not only capable of wielding his master's power but also had access to all of the Quirks All For One himself possessed.[6] However, due to the operation being only 75% completed, Tomura didn't have enough power to steal One For All, nor the complete control over the various Quirks he now possesses.[9] All For One's will is contained within the original Quirk, and has been using Tomura's anger to fuse him and Tomura's wills into one ultimate being.[22]

As shown when he stole Star and Stripe's New Order, Tomura can use All For One on top of his original Decay Quirk to steal an opponent's power and promptly finish them off by disintegrating them straight after.

The Quirk responds favorably to feelings of intense negative emotions like rage and hate, similar to Daigoro Banjo's advice to Izuku about using One For All's full power by using and channelling his anger. This indignant influence is best exemplified by Tomura's affinity for it, allowing him to leave a fragment of himself behind in the form of his childhood self, Tenko Shimura, even as the All For One vestige seized temporary command of his body. By holding onto his "origin", he can never forget why he's so determined to destroy hero society and retain his sense of self. This remnant allows Tomura to override his master's vestige and, in turn, make his own will the only one residing within the Quirk with All For One suppressed, proving himself the superior wielder and its true successor.

Named Ultimate Moves[]

All For One using multiple Quirks Ultimate Quirk Combination ( (さい) (てき) の“ () (せい) ”たち Saiteki no “Kosei” tachi?): All For One combines several of his stolen Quirks to greatly enhance his right arm. It consists of 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.[3]
Omni-Factor Unleash Omni-Factor Unleash (全因解放 (ぜんいんかいほう) Zeninkaihō?): All For One summons every single Quirk he has ever stolen into one powerful attack, in an effort to succeed in his goal of reaching Tomura.[33]

Trivia[]

  • One For All is an inversion of All For One in many ways.
    • One For All gives its current user the Quirks of the previous users, but All For One takes the Quirks of people.
    • To transfer One For All is to gain the strength necessary to handle the sheer power and then ingest a DNA sample of the user who intends to pass it on, while All For One requires complex artificial means that left Tomura in pain for nearly 4 months.
    • One For All's name is an inversion of All For One, showing the differing philosophies between their wielders. The former emphasizes one using their power for the betterment of others while the latter is meant to selfishly hoard power for one's own sake.
  • The names of both One For All and All For One are in reference to the phrase "All for one, one for all" a motto commonly associated with the titular characters of the novel The Three Musketeers by Alexandre Dumas.
    • This phrase is used in the Captain Hero comics All For One and Yoichi read, and what inspired him to call himself and the Quirk as so.[34]
  • One For All, All For One, Life Force, Fa Jin, Gearshift, Spearlike Bones, and the unnamed Luminescence Quirk are the oldest known Quirks in the series.
