7) Spider-Verse
“Spider-Verse” featured Peter Parker meeting almost countless alternate versions of himself when a group of near immortal vampire like beings started travelling through the Multiverse in a bid to kill every Spider-Man, ever. To do so, this ancient family of mystical beings basically fed on all those different versions of the hero, leading to an army of Spider-Men assembling to stop them.
Honestly, Spider-Man: Homecoming would be better off dropping pretty much all of that, but having the hero meet alternate reality versions of himself on the big screen is a must, especially if Sony still want to expand his world with various spinoffs (and let’s face it, Spider-Man 2099 or Noir would be a million times better than Sinister Six or that Aunt May solo outing).
Is it too soon to have the new Spidey meet other Spideys? Perhaps, but this could work really well with the right villain and could even lead to the introduction of Miles Morales.
