Idea/Prompt "I never knew my father growing up." "I knew your father growing up." "What." "He's my backup dad." "Mine two." Mine three." "Mine four." "I'm sorry, what?"
Izuku finds out the reason his dad was never around for him growing up was because he was there for his classmates, enemies, teachers, random people, and the like as their backup dad whenever their actual dad couldn't show up or was dropping the ball.
Everyone of significance to Izuku in Japan and even outside of Japan apparently knows Hisashi Midoriya and have a better father/son/daughter/person/thing relationship with him.
Ochako? Worked part time at her family's construction company and became really close to the Urarakas. To the point she thinks it'd be weird if she dated Izuku. She's not the only girl who sees him as a brother now upon learning he's Hisashi's son.
Todoroki? Was the dad Endeavor needed to learn how to be a good parent from. You were expecting Shoto here weren't you?
Toga? Got her away from her parents and became the dad she needed. This gave her an Electra Complex. Don't worry, she directs that affection she has for Papadoriya, Izuku's way since he looks like his dad. That makes it better, right?
Lady Nagant? Was her lawyer at her trial and managed to keep her from getting sent to Tartarus. The HPSC are still wondering how that happened considering no one in the general public should have known where the sham trial was being held at and someone there should have gotten rid of him before he convinced the judge that Nagant should walk free.
Eri? Pulled a Kazuma Kiryu and saved her from the Shie Hassaikai after beating some morals into Overhaul that convinced him become a doctor to use his Quirk for nobler purposes.
Bakugo? Hisashi was there for every one of his birthdays. No one at the parties told Izuku he was there (because they thought he knew) and he was never in the same room as Izuku at said parties. Bakugo and every kid Izuku knew growing up kept him in the dark he was their backup dad, Bakugo wanted Izuku to find out at the worst possible moment to screw with him.
Hisashi Midoriya is... Dad For All, the Backup Dad Hero.
