Toshinori Yagi

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.

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.

Toshinori Yagi (八や木ぎ俊とし典のり 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 AFO. 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 casts 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 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.
