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. In his empowered form, Toshinori is a very large man with an equally-muscular and well-defined physique. He has blonde hair in blue eyes. In his non-muscular form, he's still quite tall but Toshinori's declining health reduced him to a very skinny man with sharp, angular features.
