Hey guys!! Welcome to my first ever story OwO 

this chapter isnt gonna be the start of the story as you can see from the title so lets start explaining

So in my AU deku didnt get his quirk at the age of 3 because he was a late boomer and everyone thought he was quirkless, he was late because his quirk was so strong his body couldnt handle it as a kid and since he was a kid if he got it then he could mess up and end up wrecking the world .

 His quirk was called Developing . It was sort of like monoma's quirk but he could control how long he has this quirk whether to have it forever like AFO or to keep it till the end of a fight and there were no side effects if he decides forever .

 The person he took the quirk from wont lose their quirk . As this is a very very strong quirk and he hasnt learnt to control it yet he starts to and the side effect of taking too many quirks is illness, tummy aches, migraines , body pain and dizzyness he will also find it hard to walk . And to top it all of deku has severe anxiety so if under too much preasure or pain he could have a panick attack . 

Unlike the original AU , in this one all might will NOT lose his quirk . in the original AU he lost his quirk cuz he passes it on to izuku , But in this AU Izuku just copied the quirk and kept it forever . AFO is a VERY VERY powerful quirk so it gave izuku all the side effects x3 , Bakugo was there when izuku was taking OFA as all might asked both of them together , Bakugo refused as he thought he was powerful enough so izuku took it along with some more quirks , like aizawa's quirk , nezu's quirk and a few more . 

Izuku doesnt have control on his quirk so sometimes they pick up a new quirk on their own from strangers , so while training izuku doesnt notice and ends up discovering a new quirk. 

The villians find out of his quirk and are targeting Izuku unlike the original AU where bakugo is kidnapped. And Izuku won the sports festival with first place Katsuki second todoroki third .
