The “All for One is Izuku’s father” theory is both interesting and hilarious because any time I think about it, I just imagine Toshinori finding out and having a “I love this child with every fiber of my being and he has my complete trust but how the fuck did I manage to choose the one (1) child of my arch-nemesis as a successor” moment.
