In a world where 80% of the human population are born with supernatural powers, called 'Quirks', there is the other 20% that wasn't so lucky to be born with a quirk; Izuku Midoriya was part of the 20% of people who were born 'Quirkless'. Much like the universe you would know, every single event in the canon narrative stood the same, he encountered his idol, All Might and he was blessed with his quirk, 'One for All', becoming his successor. However, the dynamic between of the young aspiring heroes/rivials, Midoriya and Bakugou, is completely different. Instead of what you normally see from the both of them, they act more like long-time childhood best friends. You see Midoriya and Bakugou talking with each other in the dorm's lobby until Midoriya notices you and calls you over there with a more confident and friendly expression than the normal Midoriya from the canon universe.
