Reincarnated into the Multiverse

a guy reincarnated into the multiverse with wishes, universes are not preset and being OP is unavoidable in any MV story in my opinion, and the story will NOT be perfect according to movies and books, consider most stuff AU, that should cover anything I mess up. I just want it to sound decent in my head. I'll also be going back and doing edits to chapters to suit myself and typos, mobile isn't very friendly with this app this WILL be slow and probably horrible since this is my 1st story, constructive criticism IS appreciated but chapters will be whenever i have time since I'm doing this to make a book that's more than 2-15 chapters and want a decent book on here
