Spider-Man 4
Low Level Spider-Man, no conection with the Avengers anymore (since the team is broken up and noboy remember about Peter anymore)
Daredevil side character
Kingpin sends Prowler after Peter
Prowler is still Donald Glover, but way more serious and fucked up, because him and Miles were both alive during the blip and got into shit with Kingpin during this time
Peter learns about Miles Morales, after searching to find out who is the Prowler
young Miles Morales get powers by the end of the movie
Tom Holland already said he wanted to make a "Mentor Spider-Man" to the next generation, so that could be Spider-Man 5
and Spider-Man 6 could be a final team up between the two
kinda like the games are doing
