Cool, okay I’m good with that, maybe you could have him use the info that Ujiko (All For One’s Doctor) was Izuku’s Doctor at one stage track him down, and steal his research so he can gain a variation of All For One like Nine from the Movie
oh MHA world, to be honest I really want there to be an MC who changes the rules for using quirks in Japan and where the MC destroys All For One's plans, especially killing the Doctor or Shigaraki and his experiments.
