All Might

Toshinori Yagi, most commonly known by his hero name, All Might, is the tritagonist of My Hero Academia anime and manga.

All Might is the former No. 1 Hero who bore the title of the world's Symbol of Peace. 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 grooming 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 "muscle form", All Might is a very large man with an equally muscular and well-defined physique, his design resembling a typical western comic book superhero. He has short blond hair, swept backwards, with two distinct tufts that stick up above his head, leaning slightly to each side, which often casts a dark shadow over his face, hiding everything but his bright blue eyes.

All Might's Golden Age hero costume consisted of a skin-tight 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", All Might is actually 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 All Might'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 "young age", All Might used to 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 western superhero stereotypes. His personality is very colorful and tends to have a lot of dramatic flair. Always sporting a giant smile, All Might usually show off a bright, borderline obnoxious, can-do attitude to inspire others. He tends to be extremely friendly and amicable, due to his popularity and years in the spotlight. However, when he reverts to his sick and scrawny form, he tends to be less energetic. He loses the need to hide his worries about the state of affairs around him behind his smile. Additionally, he avoids drawing attention to himself altogether, afraid that others might learn of his current state of health.

Two personality traits always persist in All Might whether he is in his muscle form or true form: his optimism and his oafishness. He has always had faith and hopes that someone would come along, worthy enough to bear One For All. Enough so, that he was willing to pass the power onto Izuku Midoriya soon after meeting the young man. All Might admitted that he had started losing faith in his ability to protect the world until Izuku's heroism taught him that something can always be done to fight injustice.

Izuku has compared All Might's personality to their mentor Gran Torino. Both apparently have two sides and are often playing dumb. All Might is actually more intelligent than his image would suggest, but he is still sometimes outsmarted by his students. He struggles as both a teacher of Class 1-A and mentor to Izuku. He has to use a script while teaching his class and often fails to help Izuku improve his mastery over One For All. His fellow teacher, Shota Aizawa calls him an idiot on occasion and Gran Torino says that all his strength and fame has not translated well into teaching others.

While All Might is seen smiling, laughing, and cheerful most of the time, he is extremely protective of his students and his rage will show if they're in danger. He was willing to use his Quirk beyond his time limit in order to save his students from the League of Villains. In spite of his anger, he made sure his students felt safe by showcasing his trademark smile before the fight.

All Might has a fatherly attitude towards his students (Izuku in particular) and takes pride in helping better his students as heroes. He is quick to give encouraging advice to them and often says he is proud of their improvements. On several occasions, All Might has tried to help mend Katsuki's pride and his relationship with Izuku. All Might was not afraid of pushing Izuku and Katsuki during their final exams and pulled no punches because he knew he needed to do his best to teach them both a lesson. He even used a villainous persona during their battle to get his point across, which both Izuku and Katsuki described as very intimidating. He also has a habit of adding "young" to the surname of his students whether he is speaking out loud or thinking to himself (ex. "Young Midoriya").

Abilities
Overall Abilities: All Might was recognized as the strongest hero in the world. He was the "Symbol of Peace" and such deterrent against crime that villains were largely discouraged by his presence in society. He was able to defeat All For One, a dangerous supervillain who once ruled all of Japan ages ago. He was the only user of One For All who was able to win against him. Despite winning, All Might suffered a gruesome injury at the hands of All For One that limited his maximum power output going forward.

Even after his Quirk's power was constrained by his injuries, All Might's strength and speed were unmatched though he was only able to manifest it for a limited time period. This time limit got shorter and shorter after he passed his Quirk onto Izuku. 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 three hundred blows. Izuku and Katsuki, who are among Class 1-A's elites, were completely dominated by All Might in their fight. All Might wore high-density weights during this battle and was still more than strong and fast enough to effortlessly overpower his two young proteges. Forced to once again break the limiter placed on his Quirk, All Might defeated All For One by using up his remaining power.

It should be noted that, even though he is unable to keep his Hero form for more than an instant 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.

Overwhelming Strength: A single punch from All Might could not only defeat a villain but completely change the weather shortly afterward. 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 comparable to that of a nuclear device. He quite literally beat the Shock Absorption out of Nomu and was able to clash with All For One's attacks and cancel out their highly destructive power with brute strength alone.

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. He was also able to travel over five kilometers from the bar the League of Villains was in towards the hideout where All for One was in about thirty seconds. However, according to All for One, this was actually much slower than what All Might is capable of in his prime.

Near-Invulnerability: 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 Nomu and took point blank, unrestrained explosions from Katsuki without so much as slowing down at all. All Might was even able to survive All For One's blast wave attack, a move that can cause city-wide catastrophic damage, and emerged unharmed with only some minor scratches.

Immense Stamina: in his prime years, it was noticed that All Might has never been shown to be tired even when fighting against multiple villains. Even when unleashing a punch that is far more powerful enough to destroys several cities, All Might has shown no signs of fatigue. The only time that All Might was shown to be panting and out of breath was against All for One and Nomu, and that was only due to the injury he got from the former six years ago that also limited All Might from using the maximum output of One For All.

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. The most prominent featuring of All Might's willpower was during his final showdown with All for One. 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. Indeed, one of All for One's primary strategies in their fight was to try to wear down All Might psychologically, albeit to no avail.

Former Quirk
One For All: Inherited from Nana Shimura, All Might's Quirk gave him access to nearly unlimited, stockpiled power. By channeling this power through his body, All Might had superhuman strength, speed, agility as well as invulnerability. All Might was so proficient with One For All that he was widely known as the world's most powerful person.

Super Moves

 * Texas Smash (Tekisasu Sumasshu): All Might uses a powerful straight punch that creates a mass amount of wind pressure. So much so, that All Might can level half a city with a single punch.[4] He first used this technique to save Izuku from the Sludge Villain.
 * Detroit Smash (Detoroito Sumasshu): Similar to Texas Smash, All Might uses a downward punch so powerful it creates a powerful updraft that changes the weather. He first used this to save Izuku and Katsuki from the Sludge Villain.
 * Missouri Smash (Mizūrī Sumasshu): All Might uses a focused straight chop to strike his opponent in one quick motion. This move was first used against Trapezius Head Gear.
 * California Smash (Kariforunia Sumasshu): All Might attacks with a frontal somersault leading into a downward punch. This move was first used against a villain while he was studying abroad the United States.
 * Carolina Smash (Karoraina Sumasshu). All Might attacks with a double hand chop that crosses the opponent's body. This move was first used against Nomu.
 * New Hampshire Smash (Nyūhanpushā Sumasshu): All Might blasts himself towards his enemy and smashes his body into the enemy, crushing them with his great weight. This move is first used to propel himself at Izuku.
 * Oklahoma Smash (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.
 * United States of Smash (Yunaiteddo Sutētesu Ovu Sumasshu): Using all his power, All Might delivers a massive punch, then slams his opponent into the ground with his fist. It is powerful enough to send shockwaves reverberating the surrounding area and can incapacitate enemies of extraordinary caliber such as All For One. All Might first uses this move to defeat All For One, at the cost of almost completely exhausting what remains of One For All's power in his body. The influx of power was such that his broken right arm was restored to full capacity, albeit only for a single strike.
