In his empowered form, Toshinori is a towering figure with a powerfully muscular and well-defined physique, resembling a classic Western comic book superhero. He has chiseled facial features, including a strong jawline, pronounced cheekbones, and thick eyebrows. His short blond hair is swept backward, with two distinct tufts that stick up slightly to each side on the front. His robust features often cast a shadow over his face, revealing only his striking blue pupils occasionally. 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. Toshinori's Hero persona as All Might 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 Once Toshinori 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. Above all else, he considers self-sacrifice the most noble action, coming in many forms for Toshinori, such as physically on the battlefield and mentally, sacrificing so much of his time that he barely has a private life.
