Supporting role

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. When in his hero form he is seen as always happy and undefeated. But when not in his hero form he is weak and doubtful.
