Hi! I have another au idea, Izuku havingm everyone (heroes and villains excluding Endeavor because he's a dick) as a parental figure. Like one day, Shigaraki sends Midoriya a scarf because it was getting colder in the winter times and Twice sends him handmade mittens (which are amazingly handmade and have a cute All Might symbol on them)
Dads AU I make the rules and I say everyone is a good dad here.
Endeavour? Embarrassing and overly supportive parent. His children love him but they also refuse to tell him when they have competitions or sports events because he makes flaming signs and its painfully extra. When he meets his son’s new friend (I’m gonna say Todoroki’s fire thing here is bc he hurt someone badly when he was younger) he hugs Izuku so tightly Izuku’s ribs are sore and then pretends he did no such thing.
All for One? Also a good dad. Kidnaps Izuku to take him to a baseball game. Neither of them like baseball. They give up after 20 minutes and go nerd out over quirks like they wanted to.
Twice sends clones to make sure Izuku gets home safe from school. UA once had a freak out bc a villain got into the school, turns out it was Twice showing up to give Izuku lunch because he forgot.
Shigaraki sends him videogames and then play MMOs together on the weekends, he ends up sending him compression gloves bc gaming with his hands like that must really hurt.
He just attracts parents. No one is immune to the baby boy.
