There are spoilers for Avengers: Endgame ahead.
By the time the credits roll in Avengers: Endgame, Marvel wraps up a number of dangling storylines in a satisfying way. One of the most satisfying conclusions occurs when Captain America passes on the mantle to one of his most loyal lieutenants.
At the end of Avengers: Endgame, Captain America reveals that he's retiring as the red, white, and blue super soldier, having lived out his life after traveling back in time. But before hanging up his suit for good, Cap passes on his shield to Sam Wilson/The Falcon.
Cap's passing of the torch shouldn't come as a surprise to Marvel fans. Other heroes have taken over the Captain America alias in the past, including Bucky Barnes. As of 2014, it's been The Falcon who has taken on the role as the new Captain America.
Giving the shield to Falcon makes a lot of sense, considering how alike the two characters are. But the fact that Sam is a modern day man and not someone out of his time makes him a better fit for the role compared to someone like Bucky. He is better equipped to handle 21st century problems.
The changing of the guard is likely a setup for a Disney+ show starring Falcon and Winter Soldier, where we may see how Falcon deals with his newfound responsibilities that come with the iconic shield. It's unlikely he'll immediately embrace the Captain America persona, but the show could detail how that transition unfolds.
Disney hasn't revealed much about the upcoming show starring Falcon and Winter Soldier, although it should hit Disney+ in the first year of its launch on November 12. Whether Falcon turns up in a future MCU movie with the shield remains to be seen, as Marvel is still keeping its future plans a secret.
