Mistake (Experiment Deku AU)

Izuku Midoriya was kidnapped by the LOV when he was only a little baby. His mother tried fighting back against them but they got away. They then brought Izuku to their master All For One, where he would use Izuku as his new experiment subject. All For One wanted to create a human that wasn't a Nomu, but would destroy the world when he grows up, since he isn't sure if he'll be around for that long.

But after 4 years, when Izuku turned 8, All For One finished his experiment but then they were ambushed by the police and pros, making the LOV flee. AFO tried getting away with Izuku but no such luck and Izuku was sent off to a hospital.

But after all of this, Izuku, who now liked to be called Deku, was never the same again...
