The Vengeful Vigilante: An MHA Revenge Story

this is NOT a ship fanfic, but an alternative universe I made. before All Might was the greatest hero, they went into battle with AFO, but when everyone was knocked out, an vigilante called the Vengeful Ghost used his variant of OFA, Royal One For All, to punch AFO hard enough to destroy his skull, before he can finish him off, he teleported away, AFO being scarred for life. 22 years later, 48 year old Toriyuto Midoryia, father of Izuku Midoryia, is now a successful mechanic with a great reputation within his city. but when he comes back to a dead Inko and a mortally wounded Izuku, he finally realizes...he cannot run away from his past. he has to put the suit on, and KILL. those who dared hurt his wife and child..
