toshinori yagi

Toshinori Yagi, also known as All Might, is the former No. 1 Pro 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 onto 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.

In his empowered form, Toshinori is a massive 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 backward, with two distinct tufts sticking above his head, leaning slightly to each side. His robust 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 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 atop his torso before ending around his back, over which a similar red and white design was 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 with a silver buckle with red eyes. His forearm sleeves were colored in gold; each had white lines covered in blue accents over his wrists, spiked fins on the sides of his arms, and 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 extended, his eyebrows absent and the sclera of his eyes turned black. His hair is wavy, with two long strands coming down from his hairline and framing his face. He possesses a large scar covering most of the left side of his chest, having lost his stomach and some of his lungs' respiratory system. It is common 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 Toshinori's tenure as a hero, he starts wearing clothes that fit him in his regular form, as he no longer needs big clothes that fit his muscle form.

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 in him by his mentor, Nana Shimura, who believed that the ones who smile are the ones who are the strongest. Though he can sometimes be annoying, All Might is highly 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 commends 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 to indicate his fragile health, although it might happen if he is surprised or amused. Regardless of which form All Might is currently taking, two personality traits always present in him are his optimism and oafishness.

Since his youth, All Might had always carried a single yet burdensome goal: to become a pillar of hope that people could always rely upon during harsh times. After obtaining One For All from Nana, All Might became a hero and 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. All Might has a chronic ability to save as many people as possible, a trait shared 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.

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.

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.

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.

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.
