Toshinori Yagi, otherwise known as the former #1 hero All Might, was known as the Symbol Of Peace. 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 All For One, All Might retired and ended his era as the world's greatest hero. He currently works as a teacher at U.A.
