Okay, so just so I can clear up how Peter being in the MHA world is gonna affect it, I'll clear up a few things.
So this is gonna be clarifying what happened to Peter after Dr. Strange cast him out of his universe. So when Peter caused the multiverse to start converging onto his universe, it was because Peter was there. After all, people remembered him. (In the movie) I changed this in my version of events, so the same parts where Peter's presence was the reason for the multiverse's convergence. But instead of people simply having to forget Peter, I made it so Peter had to leave his universe entirely. Like you guys read in chapter 0. And the reason for this is that Peter's soul itself was tainted. And the only way to fix everything was to. A. Completely cast Peter out beyond even the multiverse. Making it so there wasn't anywhere for the other universes to converge. Or. B. Wipe Peter's soul effectively, resetting him. Which is what Dr. Strange chose when he cast Peter out. As a sort of last good act before Peter was completely gone. Which is why Peter is in another universe. When his soul was reset, so was his universe.
So Peter's effect on his new home universe is gonna change some things. Vigilantes have more of a presence than in the original MHA story. But the effects are really felt after Peter is bitten and gets his powers. Permanently changing the universe to be more like his soul's first home universe or a variant of the MCU.
I also want to clear up how long this story will be. Going from when Peter first gets his powers at thirteen (Younger than most stories I know.) Ending when Peter is seventeen.
A/N
For any readers of this story (On Fanfic, SB, or Webnovel, I have some more details on Wattpad.) Things like Peter's suits, polls, updates, and announcements. Along with whatever else I post on there. (Random stuff mostly.) You can find my account

So yeah, just wanted to clear some things up about Peter being in a new universe and how it'll affect it.
