Miles Morales has already been teased in the Marvel Cinematic Universe, and he will inevitably cross paths with Tom Holland's Spider-Man in the future. Miles was first introduced to the Marvel lore in 2011, and he's now a mainstream character thanks to the widely successful Spider-Verse films and Insomniac video games. Spider-Man producer Amy Pascal has also hinted a live-action Miles is coming soon.
