My Hero Academia Creator Horikoshi Confirms Deku's New Power Up Bigger Than One For All

The most iconic and well-known quirk in the entirety of the My Hero Academia story is the One For All. This legendary Quirk relies on the inherited powers of its predecessors, which, with each generation, build up its strength and potential. This Quirk previously belonged to the iconic Number One Hero of Japan, All Might. However, All Might ended up passing the Quirk to his successor, Izuku Midoriya, the protagonist of the series, at the very beginning of the series. Izuku Midoriya then went on to master the Quirk as no one had done before him.
