Marvel's Thunderbolts will be the major team-up movie that acts as the finale to Phase 5 of the Marvel Cinematic Universe, bringing together a team of antiheroes, former villains, and misfits as they battle an as-yet-unknown threat that supersedes even the likes of the Avengers themselves. Currently slated for a summer 2024 release date, Thunderbolts is perhaps the most important film in Phase 5, necessitating that Marvel's films and Disney+ series leading up to its premiere be building its core team and premise. While any Phase 5 project could feasibly act as a set-up for Thunderbolts, certain titles already have direct connections to the highly-anticipated upcoming team-up movie.
