Marvel tweeted a video of 'Thunderbolts*' star Sebastian Stan covering a poster for the film with one that reads '*The New Avengers.'

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

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.
