Toshinori Yagi (八木俊典, Yagi Toshinori?), more commonly known by his hero name All Might (オールマイト, Ōru Maito?), is one of the main characters of the My Hero Academia franchise.
He was the No. 1 Pro Hero and the eighth user of the One For All Quirk, and now a staff member at U.A Academy, teaching Foundational Hero Studies. He was known to the world as the Symbol of Peace, who brought an era of peace and harmony to the world, being an ideal hero to many who admired him. He later became the mentor to Izuku Midoriya, a quirkless teenager who dreams of becoming a hero after witnessing his selfless nature, and appointed him as his new successor and 9th user for One For All.
After fighting against All For One where he used up the leftover embers of One For All completely to defeat All For One, All Might retired from crime fighting, and thus, ending his era. He was then replaced by his rival, Endeavor as the No. 1 Hero and the Symbol of Peace. Despite this, All Might still assists the students and Pro Heroes in every way he can as possible.
In Japanese, he is voiced by Kenta Miyake, who is known for voicing Muhammad Avdol in JoJo's Bizarre Adventure: Stardust Crusaders, and by voice actor Christopher R. Sabat in the English dub, who also voiced Vegeta, Yamcha and Piccolo in the Dragon Ball franchise, Yami Sukehiro in Black Clover, Roronoa Zoro in One Piece, Elfman Strauss in Fairy Tail, and Alex Louis Armstrong in Fullmetal Alchemist.

Overview[]
Toshinori Yagi, better-known as All Might, is Japan's #1. Pro-Hero and the Symbol Of Peace. When All Might was at his prime, the crime rate in Japan decreased to less than 6%. He is widely regarded as the strongest hero.
Unknown to the world, All Might was actually born Quirkless. As a teenager, Toshinori became the eighth One For All user, after inheriting the One For All Quirk from a Pro-Hero named Nana Shimura. Five years prior to the story, All Might fought a bloody duel with Japan's most powerful supervillain, All For One. All Might won the duel, although he sustained crippling injuries to his respiratory organs and lost his stomach. Subsequent surgeries reduced All Might to an emaciated, lanky and skeletal man who constantly coughed up blood and could barely maintain his muscle form for three hours a day. Even so, All Might concealed his battle with All For One and his true form from the public, maintaining his rank as the No.1 Hero for years.
Eventually, All Might meets a Quirkless teenager named Izuku Midoriya. Impressed with Izuku's resolve to save people, All Might chooses him as his successor. He also joins his alma mater U.A High, teaching Foundational Hero Studies. The story of My Hero Academia follows his successor's time at U.A, as All Might teaches the young man how to hone the immense power he's been gifted with.
Appearance[]
In his hero form, Toshinori is extremely tall and very muscular man, whose design resembles a generic American comic book superhero. His hair spikes on top of his head and his whole body has more shadows than any other character in the series regardless of the time of day, furthering his stylized appearance. His Hero Costume consists of a red, white, and blue bodysuit with golden gloves and boots, a lot like generic American superheroes. It has been shown with and without a cape. Overall, its design is considered very classic.
In his true form, he is an overly skinny man with angular features, long limbs, and neck. He has spiky, dishevelled hair with two bangs framing the sides of his face and loses his eyebrows from his hero form. 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 his Quirk's size change, but after his true form was exposed to the world, he started wearing more fitting clothes.
Note that in both forms, his eyes are sunken in. The difference is that you can see his eyes more in his true form.
Personality[]
Even as a Quirkless teenager, Toshinori Yagi possessed a strong sense of justice. He came up with the concept of "The Symbol Of Peace", to provide hope for citizens and alleviate their fears in the face of rising crime rates. He was greatly influenced by his One For All predecessor and mentor, Nana Shimura, and admired her as a mother figure. He was also mentored by Nana's best friend, Gran Torino, although he feared Gran Torino's violent sparring sessions. Nevertheless, he respected the older Pro-Hero.
In his public persona, All Might always sports a cheerful smile. He is a jovial, magnanimous, and courageous larger than life man, who presents himself as the ever-victorious Symbol Of Peace. All Might's exceptional achievements inspired an entire generation of heroes. Even the Hero-Killer Stain admires All Might as a true hero and evaluates other heroes using the Symbol Of Peace as the standard. In private, All Might becomes a more solemn individual. In his prime, he was notorious for being an extreme workaholic, ignoring the cautions of his sidekick, Sir Nighteye, and working non-stop up to 72 hours.
All Might is proud of his protege and successor, Izuku Midoriya, appreciating the boy's fearless commitment towards saving people. He also commends all students at U.A High for their courage and effort, reckoning them as true heroes. After losing his powers and retiring as a Pro-Hero, All Might dedicates himself to become a better teacher to all students, and does his best to mentor Izuku.
Despite his optimistic personality, All Might utterly loathes the supervillain, All For One. As a teenager, All Might was traumatized by the death of Nana Shimura at the hands of All For One. After becoming a Pro-Hero, All Might dedicated his efforts towards destroying All For One's criminal empire across Japan. He cannot comprehend nor tolerate All For One's crimes of exploiting people and ruining their lives. All Might is anguished upon learning that All For One's successor, Tomura Shigaraki is Nana Shimura's grandson.
In his true form, All Might becomes a more serious and focused person, although is still capable of showing his genuine smile and concern for others well-being, albeit not at his usual grandiose extent.
Regardless of what form he is in, All Might still embodies the ideals of a true hero with a good heart to match. Ever since he was young, he dreamed of becoming a symbol that others could rely on during harsh times, upon receiving his Quirk he would rise not only to become that symbol but to become a legend that would inspire countless others to become heroes and follow in his will. Even the notorious Hero Killer, Stain, regards All Might as a true hero and what every hero should be; selfless and willing to help others.
After his retirement, All Might dedicated the rest of his life to training Izuku, entrusting him with the information about the other One For All users and their Quirks.
Abilities[]

Despite his waning power, All Might goes beyond his limits to defeat a Nomu specifically created to kill him.
Overall Abilities: While officially earning the rank of the Number 1 hero of Japan, All Might was also well-recognized as the strongest and greatest hero in the world. He was the "Symbol of Peace" and such a deterrent against crime that villains were primarily discouraged by his presence in society, single-handedly bringing near-absolute stability throughout Japan, a stark contrast to the rest of the world. He defeated 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, 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.

Even when handicapped with weights, All Might can still overpower Izuku & Katsuki easily.
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 break the limiter placed on his Quirk again, All Might defeated All For One by using up his remaining power reserves.
Even though he is unable to keep his hero form for more than a few seconds after his rematch 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 intuition 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 standard form.
Despite his skinny physique in his true form, he is actually quite physically able, but isn't as powerful as when he possessed One For All. Even then, he retains some of the fighting skills necessary for the Final War. With his new support item, the Armored All Might, he was able to stand up against his arch-nemesis, All For One, whose body was being rewinded back to his physical prime due to the effects of the reversed-engineered Quirk-Destroying Drug. Despite All For One becoming younger and more powerful, All Might can compensate for his lost power by applying some of his students' skills and Quirks into the Armored All Might, enabling him to fight more creatively instead of relying on brute force like before. He also uses All For One's mental instability to distract him, mainly using his still-exposed smile to trigger his rage.
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 body strength. 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.

All Might's incredible willpower transforms One For All's remaining embers into a raging inferno.
Indomitable Will: All Might's will is evident in all his actions as a hero. He is known for saving people with a smile and his catchphrase, "I am here," two facets of being the Symbol of Peace. During the pinnacle of his battle against the U.S.J. Nomu, All Might remembered his resolve to be the Symbol of Peace, and his resolution allowed him to push beyond 100% of his power to defeat the artificial human finally. Another prominent spectacle featuring All Might's willpower was during his last two showdowns 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, despite the guerrilla warfare employed by All For One, All Might remember Nana's teachings on heroism and re-established his will, enabling the weakened hero to muster up some of his remaining power to continue fighting. Worn out of his muscle form and faced with inevitable defeat at the hands of a virtually unscathed All For One, All Might could still channel what was left of One For All to defeat All For One in a single strike. All Might possess a powerful 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. Even when All For One crushed his spine and legs, destroyed his armored suit, and blew him away, All Might's unwavering spirit presses him on to keep fighting.
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 regarding 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 correctly but without completely exhausting himself. This insight shows that All Might greatly understands 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. In contrast, the hero team would only go in without said advantages, replicating a similar experience to heroes storming a villain's 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 use 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 fighting style and was also seen advising Kyoka Jiro during 1-A's Ultimate Move training. This counsel shows that All Might has improved in providing verbal advice and feedback to his students, realizing the steps he needs to take to motivate them without giving them the complete answer.
Former Abilities[]
- One For All: All Might inherited the Quirk called "One For All." It would allow 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 that make All Might nearly invincible.
- Vestige Manifestation: All Might wielded One For All for forty years, and despite being originally Quirkless, he imbued the Quirk with his vestige. The vestige takes a crude shape of All Might, and dwells with the vestiges of past One For All users, within Izuku Midoriya. All of All Might's knowledge is transmitted to the vestiges of One For All, through his vestige. However, the vestige cannot commune with All Might unless he is in close proximity with Izuku Midoriya.
- Intimidation: Even without his powers, All Might can project his own will to intimidate others in a similar manner to Stain. However, All Might's will instead stems from his protectiveness towards Izuku and his willingness to risk his own life for his student.

- 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 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.
Equipment[]

Armored All Might.
- Hercules (エルクレス Erukuresu): Ever since his retirement, All Might has gained himself heavily armored car dubbed Hercules, using it as a means of transportation to provide aid for heroes. The vehicle itself is equipped with durable defense, strong enough to endure explosives at point-blank range.
- Armored All Might (アーマードオールマイト Āmādo Ōru Maito): In addition, Hercules is equipped with an armored battle suit that All Might used against his final showdown with All For One. The armor itself not only provides protection, but also enhances his capablities, as well as provide him powers and abilities based on the Quirks used by his students.
