Alrighty so I saw this one online but it's got me thinking. So what I read is a theory that All for One is Izuku's FATHER. It seems crazy but it lowkey MAKES SENSE. Alright so we literally never hear about Deku's dad. For all we know Inko fuckin got artificially inseminated be cause she clearly need no man. Anyways All for One is this big bad guy and leader of this League of Villains who is clearly like immortal. Who becomes like a main villain because he seems like THE SHIT. But what if really he's Izuku's dad and that's why he was made the villain.
