Midoriya Izuku becomes a vigilante. Maybe it's the hero complex, maybe it's the guilt, or maybe it's the ever growing need for a hero to stick up for the little guys; none of that matters, except for the fact that he's there. And he's going to save them all. "Them", notably being the insomniac we know and love, Shinsou Hitoshi, the mechanic, Hatsume Mei, and our resident pretty boy, Todoroki Shouto.

Izuku is raised by Nezu after Inko died giving birth and dad couldn't deal with him. Grows up with lots of pro heroes to call his family. Nedzu raises Izuku to be the most dangerous cute person you will ever deal with. This is a combination of my ao3 works: Nedzu Raising a Baby...What? And Nedzu Raising a Teenager...What?
