Izuku Midoriya, Private Eye Hero (Neran and Diapered Avenger)
 

Izuku Midoriya sat in his bed as he scrolled through his computer, looking for requests for ‘missions’, it was what he called them. See, usually he would be quirkless, but not this version of Izuku. No, this version of Izuku had a quirk, however, it wasn’t exactly a… well it was better if he started from the beginning. His quirk first activated when he was in his house and when he was four.

His mother, Inko, was bringing in some fresh laundry for him.

Izuku was concentrating on a feeling he had before his clothes suddenly changed so that he was in just a diaper. “What the…” He said before he started looking around, only to see his reflection and see…

An infant was staring him back in the mirror.

He widened his eyes before he waddled around to his mom, trying to figure out what happened.

"How's my baby boy?" Inko cooed as she picked him up.

“Mommy? What’s going on?” He asked, before focusing on the feeling again, this time trying to reverse it.

All Inko saw was her little baby boy.

Izuku watched as his room became a nursery as he kept trying to reverse it.

Inko checked Izuku's diaper to see if he needed a change.
