17 Moments That Will Define Upcoming MCU Movies

4. Captain Marvel Joins The Team - Avengers 4

Though she may appear very briefly in Infinity War, we're being led to believe as a fanbase that Captain Marvel won't appear properly for the first time until her stand-alone movie. And a cameo or post-credits sting setting that movie up aside, that means we won't get to see Brie Larson's new all-powerful hero join the Avengers' fight against Thanos until Avengers 4.

Given how powerful she is, it's likely that Marvel's introduction will be a major turning point for the Avengers. Could it be that the time travelling element of the movie is introduced primarily to go back and rescue her from her original fate to bring her to the fight against Thanos?

How ever it's set up, having a new hero debut in Avengers 4 when there's already so much more going on is as brave as it is surprising, and that SHOULD mean it's done with lots of fireworks.
