All For One (Character)

# All For One

## General Description

Shigaraki, known more commonly by the alias (and name of his quirk) All For One, is a large man with white hair and red eyes. He is often seen wearing a black suit and fedora hat. He's well known for his intimidating smile and manipulative behavior, along with his indomitable will and keen intellect.

## History

Little is known about Shigaraki before his rise to power. It is understood that he was born in the second generation of quirk users, and that his parents were alive at least until his younger brother, Yoichi Shigaraki, was born.

During the chaos of society after quirks came into being, Shigaraki begun to unite people under his rule by using a quirk that could STEAL the quirks of others, and also grant quirks to others. This quirk came to be called All For One, as did Shigaraki himself. For many years he stole quirks from many individuals, and used them as his own to amass power, or to give quirkless individuals a quirk of their own, thus gaining their loyalty. His quirkless younger brother, Yoichi, was against this, claiming that All For One was acting only out of selfish desire. To get his brother to submit to him, All For One forcefully gave him the Power Stocker quirk. Unknown to either of them, Yoichi actually DID have a given quirk, with the ability to transfer itself to another person. The Power Stocker quirk "stockpiled" the Quirk Bestowal ability, and fused to create a new quirk, capable of stockpiling raw power, and transferring that power to another person for their use. This quirk was called One For All. The sickly Yoichi attempted to face his brother with this power, but was unable to make full use of One For All due to his weak constitution. In the end, he chose to pass it on to a successor, in the hopes that someone in the future could defeat All For One.

For the next century, All For One pursued the wielders of One For All. He desired to steal the quirk, but discovered that he couldn't. As a function of the Quirk Bestowal quirk, One For All could only be transferred if the wielder wills it. As such, All For One was unable to steal it. He killed both the second and third users of One For All, but lost track of it when it passed down to the fourth. He recovered the trail when the fifth user emerged, but was still unable to steal the quirk. This pattern repeated with the sixth and seventh users, with All For One killing each one, but without stealing the quirk. It was the eighth user of One For All that was the turning point in this pattern.

The eighth user of One For All, Toshinori Yagi, was the most proficient user of the quirk at that point. The reason: he was originally quirkless. After inheriting the quirk, Toshinori quickly mastered the god-like amount of power stockpiled within the quirk after generations of users, and became the most famous hero in Japan, All Might. All For One quickly attempted to steal the quirk, or at the very least, kill it's user once and for all. However, this time, and for the first time ever, All For One was defeated by All Might, a user of One For All. This resulted in him becoming severely wounded, and forced to retreat into hiding, although, All Might also received a serious wound in turn.

In the time after his defeat, All For One stayed hidden, having his underlings such as Kyudai Garaki and Gigantomachia, collect the quirks he'd use to repair himself. In the end, this proved to be fruitless, as his wounds had cauterized, and could not be fixed with quirks like Super Regeneration. Additionally, All For One had numerous projects on the side, namely, finding a new vessel. Along with his damaged body, All For One knew that he'd never be able to steal One For All himself. So, in an attempt to fix both problems, he begun to create potential bodies that he could transfer his consciousness and quirk to. The prime candidate for this was a boy named Tenko Shimura, who All For One had deceived and groomed to become the "next me", as worded by the villain. In addition to a healthy body, Tenko Shimura, renamed by All For One to Tomura Shigaraki, had developed a deep hatred of the world, and specifically, heroes. All For One theorized that, with enough of this hatred, he could actually overcome One For All's anti-theft property. And so, the master plan to steal One For All begun.

Six years after their first true battle, and All For One's defeat, All Might fought the villain yet again. With both of them limited by their wounds, the fight was still more or less on equal ground. Despite this, All For One was defeated yet again by All Might, but at the cost of All Might using the last remains of One For All's embers, left over from when he passed the quirk onto the ninth user, Izuku Midoriya. With his defeat, All For One left everything to his successor, Tomura Shigaraki, and quietly (yet not so quietly) went to Tartarus, the maximum security prison for the most dangerous villains.

After approximately a year's time, All For One broke out of Tartarus thanks to a joint effort by himself, and the new "symbiotic" consciousness that now resided within Tomura Shigaraki after getting the ORIGINAL version of All For One (quirk) implanted within him. As stated by the villain, "the quirk inside me now is just a duplicate of my original quirk". With the prison break successful, All For One now focused on completing the first phase of his plan to steal One For All.

As stated by All For One, in order to transplant his consciousness into Tomura's body and take FULL control, it was necessary to "complete" the transplant of the All For One quirk itself. As such, All For One immediately dedicated his main focus to completing Tomura during the period after his breakout. The villain appeared to have done so, more or less, but was not able to completely take over Tomura's body before confronting the heroes at U.A.

In the war between the heroes and villains, All For One was unsuccessful in taking over Tomura's body, but was however able to Rewind his own body back to it's prime. Assisted by his recovered power and new-found strength, he was able to defeat all of the heroes in his way, until finally getting to Izuku Midoriya. Unfortunately, he was forced to kill the boy, as he learned that it truly WAS impossible to steal One For All. With it's ninth user dead, and no successor, One For All lost, once and for all, to All For One. In the aftermath of his victory, All For One became the dark ruler of Japan once more, as the self appointed Demon Lord.

## Quirk

Shigaraki's quirk is All For One. By touching the potential target, Shigaraki can steal their quirk, and use it as his own. Alternatively, he can transfer the stolen quirk to another individual.

All For One can be used to steal and amass numerous quirks, with any variety of abilities. By using these quirks in combination, it can lead to devastating effects, granting the user near god-like power. As of current, Shigaraki has amassed countless quirks, some of which are:

* **Hypertrophy:** Allows him to massively increase the size and power of his arms.

* **Rivet Stab:** Manifests black tendrils with glowing red cracks that can grab things with precision or simply impale.

* **Super Regeneration:** Allows him to heal wounds at incredible speed and recover from certain-death injuries.

* **Hardflame Fan:** Manifests a "wall" of flames to block an incoming attack.

* **Search:** Allows him to locate and analyze targets from a distance.

* **Air Canon:** Allows him to fire blasts of highly compressed air from his hands.

* **Multiplier:** Allows him to multiply the number of arms he has.

* **Kinetic Booster:** Amplifies the kinetic energy of an attack. He has four copies of this quirk.

* **Strength Enhancer:** Amplifies the strength of an attack. He has three copies of this quirk.

* **Warping:** Allows him to manifest pools of black goo that teleport those it envelopes to or away from him.

* **Springlike Limbs:** Allows him to coil up his muscles for enhanced strength.

* **Forced Quirk Activation:** Allows him to forcibly activate the quirk of someone he touches. Works with Rivet Stab.

* **Impact Recoil:** Allows him to return the force of an opponent's attack.

* **Infrared:** Allows him to sense the world through infrared scanning.

* **Life Force:** Doubles his lifespan but sacrifices mobility.

* **Radio Waves:** Allows him to emit signal jamming radio waves.

* **Fierce Wings:** Grants him large red wings on his back that aid in flight. The feathers can be fired from them and controlled remotely.

* **Unnamed Telekinesis Quirk**: Allows him the ability to levitate objects with his hand. He used it to levitate his medical device once freed from Tartarus.

* **Unnamed Mind Control Quirk**: Allows him 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 Levitation Quirk**: Allows him to levitate in the air.

* **Unnamed Lie Detector Quirk**: Allows him to sense whether a person is lying or if they possess any semblance of ill will.

* **Unnamed Razor Blade Quirk**: Allows him to create crescent shaped razor blades.

* **Unnamed Ooze Quirk**: Allows him to generate a muck-looking substance which can cover and dissolve an area.

* **Unnamed Mouth Quirk**: Allows him 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.

* **Unnamed Vibration Detection Quirk**: Allows him to enhance his senses about his surroundings, giving him a superhuman awareness of the world around him.

* **Unnamed Glue Quirk**: Allows him 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**: Allows him 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.

* **Unnamed Body Appendages Quirk**: Allows him to grow appendages from his back in the shape of wings that can serve to expand the usage of his Unnamed Black Lightning Quirk.

* **Unnamed Black Lightning Quirk**: Allows him to shoot black lightning bolts from his body. He uses this in combination with his Unnamed Body Appendages Quirk.

As a function of how quirks work, All For One contains a "vestige world" that holds the consciousnesses of the original owner of the stolen quirks. They can, in special cases, disrupt and hold back the wielder of All For One if given a chance, even stopping the activation of the quirk itself. A duplicate version of All For One will find it harder to deal with than with the original version.

Additionally, the longer a stolen quirk is kept, the more powerful it becomes. This process is slow, like with Shigaraki's unnamed Lie Detection quirk, which he's had for many decades now.

## Current Status

Currently, All For One is facing Masahiro Kojaku in their final battle. While the fight is even, it could tip any moment, with the villain's ultimate goal being to steal Masahiro's Capacitance quirk.
