My Hero Academia's U.A. Hero Academy features some of the strongest students harnessing quirks with the potential to one day turn them into a Pro Hero. Quirks are powers granted at birth and unlocked at an early age, giving those who possess the powers a choice to use them for good or evil. Not everyone is born with a quirk, as those who fail to unlock their own powers are referred to as quirkless. Such is the case for the main protagonist of the story, Izuku Midoriya, who failed to awaken a quirk until one was passed down to him by the former Number-1 Hero, All Might. Once a quirk is unlocked, those who possess special powers will be expected to strengthen their abilities and become powerful heroes.
