Warning: This article contains Thunderbolts* spoilers.] The Fantastic Four have taken their first steps into the Marvel Cinematic Universe. There are four movie-ending reveals in Thunderbolts*, with the first being that the final film of Phase 5 is an Avengers movie after all.

By the end of Thunderbolts* the rag-tag group of sidekicks and antiheroes has emerged as the collective savior of New York. A supersoldier serum test subject named Bob (Lewis Pullman) tries to become the superhero Sentry but loses control of his powers and becomes the villainous Void.

The 'Thunderbolts' post-credits scene sets up 'Fantastic Four' and 'Avengers: Doomsday' as the New Avengers are officially formed.
