So, all for one found one of izuku’s hero analysis book and found them interesting and in turn found izuku midoriya a good candidate for his quirk, it takes a while for izuku to say yes since he still wants to save people

All for one discards Shigaraki as his successor and izuku is his new one , but he didn’t fully give up Shigaraki, so he just turns him into one of izuku’s servants

The rooftop with all might still happens, but since all might was smart about trading the sludge villain To a hero early on his encounter with izuku, who said no harshly

Since izuku is smart enough to not attack at the US, he attacks them at the training arc, while building his team

So here’s where things starts to turn around for the heroes side

Aizawa is his cannon self as he expels some of the class 1a who didn’t fit in or was just useless (shouto, denki, henta, soji, the tape guy, and Mina) and later on the school year leading up to the USJ, ochako and jiro and invs girl quit UA due to aizawa not dealing with mineta and his perviness, and not just two weeks later Momo quit since she wasn’t having it with aizawa as a horrible teacher

Her family disowns her and she runs away but izuku finds her and convinces her to join him, the others already did

Izuku and all for one fight all might, and all for one tells all might that his mentor/mother figure nana shimura was manipulating him to give him the one for all quirk since she was on borrowed time, the quirk kills it’s quirked users by shortening their time, and she gave the cursed quirk into him, afo tells all might that nana didn’t care for him or loved him and only wanted him to take the power to live on the legacy that was one for all

All might couldn’t accept this, and dies in the hands of all for one, the heroes has lost, with izuku’s help and shouto’s statement, endeavor quickly was put in jail for his crimes, along with several pro heroes

The villains has won, and made a better world where everyone can live in peace

The end
