Bnha au where Izuku unknowingly has a quirk that at an unknown trigger swaps the quirks of two people within a 50 meter radius and that range only gets bigger after getting OFA
Series: Boku no Hero Academia AU Criteria: Izuku has a quirk that allows him to swap quirks of two people within 50 meters, and now he has OFA powering it. AU title (optional): Trademan
Izuku has never activated his quirk, because of the quack that did a discredited test and came back with a false-quirkless diagnosis. So he never considered that he had a quirk, and the reports of swapping quirks must have been a sickness. He is fascinated as it is quirk related, and really cool.
The first time he has a clue that something's going on is when All Might tries to offer him a hair, and he suddenly has One For All. He misses the entrance exam, but Nezu and All Might convince him to take an apprenticeship with Nezu, who makes him his personal students while they investigate his quirk, One For All, and his parental lineages.
So anyways, Inko Midoriya, mind telling us how you came to meet your husband All For One? When was the last time you saw him? Oh, don't mind us, he was just supposed to have been dead at the time. Did you know your son had a quirk? Oh, here's a more comprehensive report, and here's the paperwork to make him my personal student and All Might's apprentice. More wine?
Bakugou is… well he can't stand not being told everything, so Izuku gives him a full briefing on what happened with the quirk doctor, Nezu helps ensure no secrets are slipped in, and then he is brought into Nezu's office for a very serious discussion. Izuku is asked to get some copies from a teacher, and then Nezu begins explaining the rules and what is going to happen should Katsuki decide HIS student was someone to target in the future.
Izuku spends time split between the two Heroics classes as Nezu tests him out of a few lower level subjects, and decides to make Izuku into someone else's problem, intentionally. Whose? Well yes, them.
