Marvel Studios has reportedly changed the ending of Phase 5's upcoming Thunderbolts, proving that one major MCU problem might actually be being solved. Marvel Studios chief Kevin Feige confirmed the development of a Thunderbolts movie in 2022, with the Jake Schreier-directed project set to bring back reformed villains and antiheroes from the MCU's past to form a new superpowered team. In lieu of any Multiverse Saga Avengers projects, Marvel Studios' Thunderbolts will mark the first major crossover event since 2019's Avengers: Endgame, though the fates of the Thunderbolts team members were almost very different to those of the original Avengers.
