In one world when Izuku Midoryia saves Katsuki Bakugou from the sludge villain Toshinori Yagi gives him One For All, that is not our world in our world, in our world Izuku Midoriya enters UA's Hero course quirkless. Shota Aizawa thinks that due to his quirklessnes he does not have the potential or drive to be a hero so expels him right there and then. That was their first and most Fatal mistake.

Izuku Midoriya has become Umbra Imperatoris: The Shadow Emperor

Living by his new motto "Potestatem Autem Infirma" Power Of The Weak.
