Toshinori Yagi aka **All Might** is the former No. 1 Hero and Symbol of Peace from Shonen anime/manga franchise My Hero Academia. He is also the mentor to the show's main protagonist, Izuku Midoriya.

## Background

Before he was the Number One Hero known throughout Japan as All Might, Toshinori Yagi was born quirkless in a world where crime rates were high due to evil running rampant thanks to the influence of All For One. When he realized this as a teenager, he believed that the world needed a “Symbol of Peace” that would inspire people and bring in a new age of harmony. Toshinori chose to become that symbol to make sure there would be a world where everyone can smile and live happily ever after together.

Toshinori was trained by the 7th user of One for All, Nana Shimura. She was the one who passed One for All to Toshinori. However, she sacrificed her life when All For One attacked. Afterward, Toshinori was trained by Nana’s close friend Gran Torino, who was also his homeroom teacher at U.A. Academy. After graduation, Toshinori traveled to the United States for training where he met David Shield and later Melissa Shield. Eventually, Toshinori went back to Japan to continue his work of heroism, becoming the Symbol of Peace and Number 1 Hero as All Might.

The crime rate dropped below 6% thanks to All Might, but All For One was still around. Toshinori gained a new partner in Sir Nighteye, who acted as the brains of their partnership. Eventually, All Might battled All For One and defeated him but at the cost of critical injuries that permanently reduced his use of One for All. While All Might refused to step down as the Number 1 Hero and Symbol of Peace, he knew that he needed a successor for One for All. 5 years later, he became a teacher at U.A. Academy in order to find his successor.

It was after those 5 years that All Might came across Izuku Midoriya, a young boy who was born quirkless. Initially, Toshinori told the young boy that it may not be possible for someone to become a hero without a quirk. However, after seeing young Midoriya risking his life to save fellow classmate Katsuki Bakugo from a villain, Toshinori realized that he found his successor.

Toshinori passed down One for All to Midoriya and helped the boy train in order to master the quirk. It even helps that Midoriya got accepted into U.A. Academy. However, there still existed threats toward Midoriya, U.A. Academy, and the hero society such as the rise of the League of Villains and the return of All For One. While Toshinori continued to teach and train Midoriya into becoming the greatest hero despite the villainous threats, his time as All Might continued to shorten.

Eventually, All Might entered a rematch with All For One. After a lengthy, hard-fought battle, Toshinori emerged victoriously. However, the fight had cost him the last remnants of One for All, ending his career as the Number 1 Hero and the Symbol of Peace. Despite all that, Toshinori devoted the rest of his time on Izuku Midoriya’s training and development into becoming the next Symbol of Peace.

## Powers & Abilities

* **One For All:** The origin of One For All started with two brothers. One brother, who would later become the villain All For One, has the power to steal other people’s Quirks and transfer them into someone else. The other brother, on the other hand, had no Quirk. At least, not that they were aware of. All For One forcibly transferred a Quirk into his brother, the ability to stockpile power within one’s own body. However, it turns out that the brother did have a Quirk, which only has the ability of it being transferred to other people. These two Quirks merged, becoming One For All. Knowing he couldn’t beat All For One, the brother decided to entrust One For All to future generations so it can grow, with the hope that they can defeat All For One with it. All Might is the 8th person to have One For All, which has grown stronger since All For One’s brother had used it. By channeling this power through his body, All Might gained superhuman strength, speed, agility, and durability. All Might proficiency with One For All allowed him to be widely known as Japan’s Number 1 Hero.
	+ **Immense Strength:** All Might's most distinguishable trait was his boundless levels of immense strength. A single punch from All Might could not only defeat a villain but completely change the weather subsequently. It also has the power to completely destroy several city blocks from the wind pressure it creates. Despite becoming severely weakened since first meeting Izuku, All Might's pure overwhelming strength is still comparable to that of a nuclear device. He quite literally beat the Shock Absorption out of Nomu, forced Izuku and Katsuki into fleeing rather than continue fighting him head-on, and clashed with All For One's attacks and cancel out their highly destructive power with brute strength alone. After defeating Nomu, All Might himself admitted that, compared to his prime in which he could've defeated Nomu with five hits, it took over three hundred blows to defeat the bio-engineered creature. This is another testament of All Might's weakened state.
	+ **Immense Speed:** In conjunction with his immense level of physical strength, All Might possesses an equally impressive amount of speed. When he arrived at the U.S.J., All Might moved a remarkable distance from the gate and simultaneously incapacitated villains in the blink of an eye. Tomura even says that he was completely unable to track his movements despite the latter being slower than he once was. All Might was also able to swiftly defeat multiple Nomu and travel 5 kilometers from the League of Villains Bar, towards All For One's location at the Nomu Factory, all in thirty seconds after the Nomu were warped by All For One himself. However, according to All For One, this was actually much slower than what All Might was originally able to accomplish in his prime. Even in his weakened state, he was fast enough to travel from Might Tower to the Tokyo Egg in mere seconds. In his prime, he proved swift enough to single-handedly defeat the army of Instant Villains created by All For One and save nearby children all in the span of three seconds.
	+ **Immense Durability:** All Might had extreme durability, almost to the point of being completely invulnerable to attacks. He sustained no life-threatening damage from his battle with the U.S.J. Nomu and took point-blank, full-power explosions from Katsuki without showing any signs of injury. All Might was even able to survive All For One's enhanced Air Cannon, a move that can cause catastrophic, city-wide damage due to being amalgamated with many other Quirks, and emerged virtually unharmed, albeit with only some minor scratches.
	+ **Immense Stamina:** In his prime years, it was noticed that All Might has never been shown to be exhausted even when fighting against multiple villains. The only time that All Might was shown to be panting and out of breath was against All For One and the U.S.J. Nomu, and those cases were only due to the injury he received from the former six years prior that also limited All Might from using the maximum output of One For All. In his prime, All Might was able to do more than seventy-two consecutive hours of hero work and still had enough energy to respond to an emergency call in Osaka.
* **Moves:**
	+ **California Smash:** All Might attacks with a frontal somersault to built up momentum and air pressure and is then released in a smash.
	+ **Carolina Smash:** All Might runs towards an enemy while keeping his hands in a cross position, then in a downwards cross chop to the enemy's head. This move is first used against Tomura, but it is intercepted by a Nomu, who withstood the full force of the attack, seemingly unharmed.
	+ **Detroit Smash:** All Might performs that same attack as Texas Smash except this move is with a downward punch instead of a straight punch. The punch is powerful enough to create a shock wave large and powerful enough to clear the weather. This move is first used to save Izuku and Katsuki from the Sludge Villain.
		- **Double Detroit Smash:** All Might and Izuku use One For All at 100% and combine their Detroit Smash attacks to create a smash more powerful than anything they can accomplish alone. First used this move to defeat Wolfram.
	+ **Missouri Smash:** All Might runs towards an enemy while keeping his hand flat and hits the enemy on the head while running past them in order to knock them out. This move is first used against Habit Headgear.
	+ **Nebraska Smash:** While throwing a punch, All Might rotates his arm to create a tornado. This move is first used to destroy a swarm of two hundred Mini-Bombers.
	+ **New Hampshire Smash:** All Might punches the air while in the air to propel himself backwards towards his enemy and smashes his body into the enemy, crushing and injuring the enemy with his great weight. This move is first used to propel himself at Izuku.
	+ **Oklahoma Smash:** All Might whirls around while enemies have latched onto him, spinning with enough force that when they are released they are easily thrown through concrete. This move is first used against Nomu however it was named during the Kamino Ward Incident.
	+ **Texas Smash:** All Might throws a punch in order to create wind pressure in order to blow objects and people away. This move is first used to save Izuku from the Sludge Villain.
	+ **United States of Smash:** All Might throws an immensely powerful punch and smashes his target into the ground. As All Might's final and strongest move, the impact of this smash is so great that it can not only reverberate shock-waves and leave massive craters in the ground, but also spawn twisters powerful enough to carry nearby buildings. This move was used to defeat All For One and marked the end of All Might's hero career.
* **Overall Abilities:** All Might was recognized as the greatest hero in the world. He was the "Symbol of Peace" and such a deterrent against crime that villains were largely discouraged by his presence in society, single-handedly bringing near-absolute stability throughout Japan, a stark contrast to the rest of the world. He was able to defeat All For One, infamously known as the world's most powerful villain, twice; a feat that all the previous wielders of One For All could not. Despite winning however, All Might suffered a gruesome injury at the hands of All For One that limited his maximum power output going forward, gradually reducing his sheer might and how long he could use his power at all. Even after his Quirk's power was constrained by his injuries, All Might's strength and speed were unmatched. After he passed his Quirk onto Izuku, relying on the residual energy of One For All made his strength and time limit decrease more rapidly. Even so, All Might could still defeat villains on his own that groups of normal Pro Heroes struggled against. By pushing his power beyond its reasonable limits, All Might defeated Nomu, who was created specifically to kill him, with over 300 blows. Against Izuku and Katsuki, who are among Class 1-A's elites, he completely dominated them in their fight, even while wearing high-density weights. Forced to once again break the limiter placed on his Quirk, All Might defeated All For One by using up his remaining reserves of power. Even though he is unable to keep his hero form for more than a few seconds after his final battle with All For One, All Might still keeps a keen intuition and sharp reflexes, which helped him hone his skills as a hero ever since he acquired his powers. This is shown in his observations regarding Izuku's use of One For All, and the fact that he was capable of catching one of Mei Hatsume's "babies" coming in from behind with minimal effort in his true form. Despite his physique in his true form, he is actually quite physically able but isn't as efficient compared to when he is in his hero form.
* **Trained Muscles:** Usage of One For All requires the user to have strong muscles, as One For All is a lot to handle and could cause the user's body to be blown apart if they don't possess the necessary strength of body. Gran Torino said that All Might, in particular, had a strong body that allowed him to master One For All much faster than previous users.
* **Indomitable Spirit:** All Might's will is clear in almost all of his actions as a Hero. He is known for saving people with a smile and his catchphrase "I am here", two facets of him being the Symbol of Peace. During the pinnacle of his battle against the U.S.J. Nomu, All Might remembered his resolve of being the Symbol of Peace, and his resolution allowed him to push beyond 100% of his power in order to finally defeat the artificial human. Another prominent spectacle featuring All Might's willpower was during his final showdown with All For One. One of All For One's primary strategies in their fight was to wear down All Might psychologically, such as taunting All Might by mentioning the latter's former mentor and predecessor, Nana, as well as revealing that Tomura Shigaraki is her grandson. The first taunt enraged All Might, while Tomura's kinship to Nana made him despair greatly. However, in spite of the guerrilla warfare employed by All For One, All Might remembers Nana's teachings on heroism, and re-established his will, enabling the weakened hero to muster up some of his remaining power in order to continue fighting. Worn out of his muscle form and faced with certain defeat at the hands of a virtually unscathed All For One, All Might was still able to channel what was left of One For All to defeat All For One in a single strike. All Might possesses an extremely strong presence that has struck fear into others, such as Izuku and Katsuki during the Final Exam. This aura was strong enough to cause two villains to freeze in terror even though they'd been prepared to kill him and despite him being powerless.
* **Teaching:** While All Might has shown to be a poor teacher on occasion, as he lacks proper teaching practice and required a script for his first lesson, he does show to have his exceptions when it comes to training and hero practice. All Might was able to help train Izuku Midoriya's skinny body into a muscled vessel for One For All, having created a training regimen that would allow Izuku to train up his body and safely inherit his Quirk in the limited space of ten months. Furthermore, he realised that Izuku had been deliberately pushing himself to go even further, revealing that he designed the regimen so Izuku could train his body properly, but without completely exhausting himself. This shows that All Might does have a great understanding of physical training and the human body's limits. His first practical battle lesson was also designed realistically, with him giving the villain team earpieces to communicate and a map of the building, whilst the hero team would go in without said advantages, replicating a similar experience to heroes storming a villains hideaway without proper preparation. He also assigned 1-A's partners randomly, as Izuku pointed out that Pro Heroes often have to team up on the spot and make use of their collaborative skills. Following his retirement, it is revealed that he's studied teaching more intently from a guidebook, as he commended Izuku for having developed his own fighting style and was also seen giving advice to Kyoka Jiro during 1-A's Ultimate Move training. This shows that he has improved in giving verbal advice and feedback to his students as well, realising the proper steps he needs to take to motivate them without giving them the complete answer.

## Equipment

* **High Density Weights:** All Might and the rest of the teachers use these bracelets to give themselves a handicap while they are fighting their students.
* **Air Pressure Shooting Torso Armor:** At one point, All Might wore armor over his torso that was designed to aid him in releasing shots of pressurized air. It was designed to work with 20-30% of his power. Due to All Might's close range fighting style, the bulky armor ended up being more baggage than it was worth, and it kept breaking, so All Might decided to stop using it.

## Feats

* Defeated numerous other villains over the course of his hero career

## Weaknesses

* **One for All:** His use of One For All can be very destructive, so he will not go max out if others will get harmed in the crossfire. One For All also does not give the user a healing factor since All Might’s stomach was lost and his respiratory system was damaged beyond repair. When All Might suffers a major blow, his usage of One For All becomes limited and shortens every time he overuses it. Most importantly, his United States of Smash is only a last resort since using all of his power will permanently disable his connection from One For All forever.
