SPOILERS are ahead for the MCU up to Black Widow, which is playing in theaters and on Disney+ Premier Access.
Since the Marvel Cinematic Universe began, the end credit scenes have become important bookends to setting up what’s to come for fans through the studio’s upcoming projects. However, following Avengers: Endgame it’s not quite clear what next big event is being set up. There are musings of the multiverse being a huge part of the next chapter, but the first official Marvel movie in Phase Four, Black Widow, is also teasing something else: the Thunderbolts. The Thunderbolts are essentially Marvel’s own version of Suicide Squad, as in they are villains who become heroes.
