All Might also known as the Symbol of Peace is a Pro Hero who also happens to be the eighth holder of the One For All Quirk. He inherited his powers from Nana Shimura and saved humanity from the villains many times throughout his illustrious career. When it was finally time to hang the boots, he chose a quirkless boy named Izuku Midoriya as his successor and slowly took a backseat as his days as No. 1 Pro Hero slowly came to an end.
