All Might

**Toshinori Yagi** ( *Yagi Toshinori*?), also known as **All Might** (オールマイト *Ōru Maito*?), is the former No. 1 Pro Hero who bore the title of the world's **Symbol of Peace** (平和の象徴 *Heiwa no Shōchō*?). He teaches Foundational Hero Studies at U.A. High School.

All Might was the eighth holder of the One For All Quirk after receiving it from Nana Shimura. He has since passed the torch to Izuku Midoriya, whom he is training to be his successor. After using up all the embers of One For All to defeat All For One, All Might retired and ended his era as the world's greatest hero.

## Appearance

In his empowered form, Toshinori is a very large man with an equally muscular and well-defined physique, his design resembling a typical western comic book superhero. He has chiseled features on his face with a strong jawline, pronounced cheekbones, and bushy eyebrows. He has short blond hair, swept backwards, with two distinct tufts that stick up above his head, leaning slightly to each side. His strong features regularly cast a dark shadow over his face, hiding everything but his bright blue eyes.

Toshinori's Golden Age hero costume consisted of a skintight blue bodysuit decorated with a red symbol that somewhat resembles a "Y", designed with a white diamond at its center, with white lines connected to it that trace from his chest to his back shoulders; the lines trimmed with the aforementioned red symbol. The symbol appeared to have wings on the side that ran from the atop his torso before ending around his back, over which was a similar red and white design absent of the white diamond. Large white patches lined with red-covered each side of his hips before ending at his lower thighs, and he wore a gold belt that had a silver buckle with red eyes. His forearm sleeves were colored in gold that each had white lines covered in blue accents over his wrists, and had spiked fins on the sides of his arms, his feet were covered in shin-length gold boots trimmed with white and red accents.

In his "true form", after sustaining permanent damage from All For One, Toshinori's declining health reduced him to a very skinny man with sharp, angular features and long limbs, his neck long and his eyebrows absent. He possesses a large scar that covers most of the left side of his chest, and it is not uncommon for him to spout blood from his mouth when excited or surprised. He typically wears baggy clothing to accommodate the change in body mass between forms, but after the end of Toshinori's tenure as a hero, he starts wearing clothes that fit him in his true form, as he no longer needs big clothes that fit his muscle form.

In his early career, Toshinori was a lean but fit young man. In his empowered form, his facial features were noticeably softer. In both his normal and empowered form, he did not have shadowed eyes on his face, completely showing his white sclerae while retaining the deep blue irises of his eyes, possibly showing how he was not a shell of his former self.

## Personality

All Might's hero persona appears to be derived from comic book superhero stereotypes: exuberant and filled with dramatic flair. He always protects and saves innocent people with a huge smile. The habit of smiling was ingrained to him by his mentor, Nana Shimura, who believed that the ones who smile are the ones who are the strongest. Though he can be annoying at times, All Might is extremely friendly and amicable due to his popularity and years in the spotlight, always taking his time to interact with fans.

Once All Might reverts to his true form, he becomes reserved and solemn, avoiding attention in direct contrast to the grandiosity of his hero identity. While he's an optimist, he still ensures his goals are grounded in reality. When a Quirkless Izuku tells him about his goal of becoming a hero, All Might praises him for having a dream, but reminds him to stay realistic and suggests he enter another profession that helps people. He considered the harsh words necessary to save the boy from long-term frustration. In this form, he frequently vomits blood as an indicator of his fragile health, although it might happen if he gets surprised or amused enough. Two personality traits that seem to be always present on him, regardless of which form All Might is currently taking, are his optimism and oafishness.

Since his young days, All Might had always carried a single, yet burdensome goal in his mind: to become a pillar of hope that people could always rely upon during harsh times. After obtaining One For All from Nana, All Might rose to become not only a hero but a legend, thanks to his seemingly endless competency and charisma. No matter who or what he faced, All Might would stand up triumphantly every time, one battle after another, inspiring the world and sending fear to the hearts of villains everywhere. He has a chronic ability to save as many people as he can, a trait he shares with his successor. He exhausted himself and fell behind on his other hero duties, such as filing paperwork. Though he was embarrassed by it, he still gratefully accepted the offer of Sir Nighteye and (later) Naomasa Tsukauchi to file his reports.

After his fight against All For One, he considered it necessary to keep his weakened state hidden from the public, for the sake of keeping up morale. Unfortunately for All Might, injuries inflicted on his body were starting to take a toll on him. Despite the concern and warnings from some of his close associates, All Might's determination to preserve society from evil prevented him from relinquishing his role as the Symbol of Peace. His smile, once a gesture that served to calm others, started becoming more of a way for All Might to hide his fears and insecurities from the general population. As time passed, All Might began to forget some of the basic principles of heroism, until Izuku, in a brave attempt to save Katsuki Bakugo from the Sludge Villain's attack despite being Quirkless, rekindled his heroic spirit and taught him that something can always be done to fight injustice.

Above all else, he considers self-sacrifice the most noble action. This comes in many forms for All Might, such as physically on the battlefield, but also mentally, sacrificing so much of his time, he barely has a private life. He believes in this core value so much, he dropped Sir Nighteye's preparations for a successor on a whim after witnessing Izuku's single act of selflessness to save Katsuki. This selflessness has served All Might well to become a symbol, as civilians trust his words, "Do not fear", truly knowing he won't hesitate to save them. The dismissal of his own safety eventually caught up to him, causing issues with both his work and personal life. As a U.A. Teacher, he couldn't help but be distracted helping people on his morning commute, shortening his time with his students. It also estranged All Might from Sir Nighteye, who disagreed on whether he should be avoiding his prophesied death or continue hero work. All Might attempted to ignore his prophesied death, keeping it secret from Izuku for a long time. At Inko Midoriya's request, he gained a new resolve to avoid it entirely; he found a greater value in his own life, knowing Izuku needed him as a mentor, not just a savior.

Izuku has compared All Might's personality to their mentor Gran Torino since both of them apparently play dumb often. All Might is actually more intelligent and perceptive than his campy image would suggest. He has a tactical mind when it comes to battle strategies and public speaking. Assessing a villain's threat level, he skillfully applies the necessary force and avoids injuries when possible. If he's in control, he even makes dramatic performances out of their defeats, as examples to other villains. His presence alone decreased Japan's crime rate by 3%. He's aware of villain tactics, such as monologuing, and actively ignores them. Only the most manipulative of villains, like All For One, can bring out rare instances of anger in All Might, such as catching him off guard and giving him a mortal injury, as well as mocking his late master, Nana, causing All Might to rise in anger, saying that he would destroy All For One's wicked ambitions and bitterly stating that the villain would die in prison.

Despite his battle intelligence, his great powers and fame make him dissociated with others' capabilities, and Gran Torino asserted this made him ill-suited to teaching. Sometimes All Might underestimates his students and is outsmarted as a result. Lacking teaching experience, he required a script in order to convey his first lesson to Class 1-A. He is also reprimanded on occasion by his fellow teacher, Eraser Head, for being sometimes unavailable for his teaching duties. However, All Might bringing his typical attitude into his teaching can be beneficial, creating an energetic and motivating environment. While his U.A. coworkers respect him as a Pro Hero, they can get frustrated with the conflict his presence brings to the school, such as attracting journalists. He has also faced criticism from the media for attracting villains to U.A.

For Izuku especially, All Might has a habit of projecting himself onto his protégé, and overestimating his limits as a result. While All Might grew accustomed to being able to use One For All at 100% instantly, Izuku received grave injuries when he did so. After receiving multiple scoldings from Recovery Girl for encouraging Izuku's self-destructive behavior, they both realized that the boy needed to be his own individual hero and develop in his own way. This is reflected when All Might told Endeavor, after taking his place as the Number 1 Pro Hero, to figure out on his own what kind of symbol he wanted to be. While All Might wishes to inspire others, he is not self-righteous and sees the value of different ideologies. He also has a respect for other professions outside of heroes, such as the Police Force, while others tend to underappreciate them.

All Might always prioritizes the lives of others over his own, considering them his responsibility. Still, All Might is deeply aware that saving everybody in the world is an impossible task, which is why he sought to become a symbol who could inspire others to take action as well. While All Might is seen smiling, laughing, and being cheerful most of the time, he is extremely protective of his students, showing a very rare instance of rage if they're in danger. He is willing to go above his limits for their safety, making sure to alleviate their worries through his trademark smile. Even after his retirement, he remains willing to provide support to the Heroes during major operations such as Mission: Humarise and the Final War.

Despite having the best intentions in becoming a symbol that everyone could rely on, All Might's debut and tremendous rise in the world of Heroes also came with unintended downsides and consequences; as a result of his immense power, society began to over rely on both him and other Heroes in general, to the extent where they would become downright ignorant in thinking that a Hero would always appear on the scene and rectify any situation, becoming more like bystanders and spectators in the process. This was unfortunately the very opposite of what he wanted to inspire in people, and would also be the main catalyst of his mentor's grandson becoming a villain when no one turned to help him, causing him to be found by All For One. In other and more extreme cases, Endeavor would go to horrible lengths in order to surpass All Might, such as creating his son, Shoto, with the intention of training him to surpass All Might as his father's successor. Furthermore, fanatics such as Stain believed that All Might was the true example of what every Hero should be, and killed those whom the Hero Killer believed were unworthy and did not meet his standards.

Another negative aspect of All Might's drive to be the Symbol of Peace and the ideal hero is that he often has a self-deprecating view of his life and work as a hero. He doesn't see himself as heroic or as some kind of paragon simply because that's what he was aiming for. He believed that because he was going out of his way to be a hero or that his goal was to be a hero rather than being heroic for the sake of altruism or compassion that it somehow reduced his accomplishments. Due to the stresses of acting like the ideal hero while fearing being found out versus being himself when he used his hero persona, he seems to have developed a minor case of imposter syndrome. As a result of this and his selflessness, All Might has a habit of placing burdens on himself and being very self-critical. When Izuku left him behind as to deal with All For One's forces and began distancing himself from everyone in fear for their well-being, All Might fell into harsh dejection, chiding his now-retired self for being unable to help and feeling as though he was only dragging everyone down in his now powerless state. It would take Stain of all people to show All Might that there are still those, both civilians and heroes, who recognize the heroic legacy that he left behind and will continue fighting for what's right, even in the face of hopelessness.

All Might has a fatherly attitude towards his students (his successor Izuku, in particular) and takes pride in helping their development as future heroes, being quick to give encouraging advice and celebrate their accomplishments, but he's also not afraid of pushing them further, even if he ends up going a bit too far. All Might has the habit of adding "young" (少年 *Shonen*?) to the surname of his students whenever he is speaking out loud or thinking to himself (ex. "Young Midoriya").

However, during the Final Exams Arc, out of all the teachers he is, by far, the most ruthless. Like his hero persona, All Might can put on a theatrical villain one, doing it to bring out the full potential of others with rough love. His sheer intimidation alone was, according to Izuku, similar to that of Stain. When Katsuki stated that he'd rather lose than seek Izuku's assistance, All Might was more than willing to force Katsuki to lose. He also punched Katsuki hard enough for him to vomit, showing he will not hold back and is willing to injure his student if that means they'll pass the exams properly. He would even go as far as to crack Izuku's back, as well as crush them both under his boot (all of which earned him a serious scolding by Recovery Girl). He later admitted that while he cared a lot about saving people (like Izuku), he also cared a lot about winning (like Katsuki).

## Abilities

**Overall Abilities**: While officially earning the rank of the Number 1 hero of Japan, All Might was also well-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.

After his Quirk was constrained by his injuries, and even after he passed it onto Izuku, relying on the residual energy of One For All, All Might's power and capabilities were still unmatched by any other hero, despite his strength and time limit decreasing more rapidly. 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 realized 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, realizing the proper steps he needs to take to motivate them without giving them the complete answer.

### Former Quirk

**One For All** (ワン・フォー・オール *Wan Fō Ōru*?): Transferred to him from Nana Shimura, Toshinori's Quirk allowed him to stockpile an enormous amount of raw power, allowing him to significantly enhance all of his physical abilities to a superhuman level. This resulted in unbelievable levels of strength, speed, agility, and durability. Seemingly unique to him, Toshinori's mastery of this Quirk enabled him to morph himself into a towering, powerfully built man to hide his identity from society.

All Might was so proficient with One For All that he was widely known as the world's most powerful person. However, most of the known feats he performed are after he'd been grievously injured by All For One, and after he started the process of transferring One For All to Izuku, so the fullest extent of his abilities are mostly unknown.

* **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 300 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.

### Ultimate Moves

* **California Smash** (カリフォルニア スマッシュ *Kariforunia Sumasshu*?): All Might attacks with a frontal somersault to build up momentum and air pressure and is then released in a smash.
* **Carolina Smash** (カロライナスマッシュ *Karoraina Sumasshu*?): 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** (デトロイトスマッシュ *Detoroito Sumasshu*?): 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** (ダブルデトロイトスマッシュ *Daburu Detoroito Sumasshu*?): 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** (ミズーリースマッシュ *Mizūrī Sumasshu*?): 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** (ネブラスカスマッシュ *Neburasuka Sumasshu*?): 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** (ニューハンプシャースマッシュ *Nyūhanpushā Sumasshu*?): 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** (オクラホマスマッシュ *Okurahoma Sumasshu*?): 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** (テキサススマッシュ *Tekisasu Sumasshu*?): 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** (ユナイテッド ステイツ オブ スマッシュ *Yunaiteddo Suteitesu Obu Sumasshu*?): 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 cannot only reverberate shockwaves 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.
