These two stories ideas you don't have to use.
Spider-man crossover with stranger things where young peter parker and aunt may and uncle ben moves to Hawkins because of the bills and peter starts being friends with Mike and his friends. He gets his powers around season 3 when Mike was pretending to be sick instead that, peter actually becomes sick and gets his powers.
Peter Parker x Eleven or Peter Parker x max.
Another Story Suggestion, cyberpunk edgerunners crossover with Cyberpunk 2077.
V story became first before cyberpunk edgerunners and v actually changes events of the story.
I wanted to give you more story ideas in distant future.
