MCU Phase 4: 9 Insane Fan Theories You Won't Believe

7. Captain Marvel Will Lead The New Avengers

A theory that's dependant on both Captain America and Iron Man departing our screens in some fashion, but one that's certainly possible all the same.

While we'll have to wait until 2019 to see Brie Larson's Carol Danvers on the big-screen (in a nineties-themed prequel no less), we know for certain that she'll be featuring in Avengers 4, in what will likely be the conclusion to the Infinity Stone saga. She's been hyped up as the most powerful superhero in the MCU, and one that - having fought across the cosmos an entire decade before Iron Man et al. - has the most amount of experience too.

That's a really interesting dynamic to present to the Avengers, especially since she was absent for two potentially world-ending events in the Chitauri Invasion and Ultron's uprising. Despite this, it's obvious that Danvers is the character best equipped to lead a team against superhuman threats, be they domestic, cosmic or otherwise.

With both Tony Stark and Steve Rogers billed for an early departure in either Infinity War or Avengers 4, it could be that Brie's Captain Marvel steps in to lead a new team, one that lacks - for the time at least - a real Captain.
