Anthony Mackie thanks fans for watching the Falcon and the Winter Soldier finale with an awesome picture of his new Captain America costume. Marvel's second Disney+ series has come to an end with Friday's finale, which introduced some major changes for the MCU. The Falcon and the Winter Soldier followed Sam Wilson (Mackie) and Bucky Barnes (Sebastian Stan) in the aftermath of Avengers: Endgame as they both grappled with their places in a changed world and several new threats. Between the Flag-Smashers and a government-backed Captain America (Wyatt Russell's John Walker), they had a lot on their hands.

The Falcon and the Winter Soldier episode 6, "One World, One People," brought everything to a head as the Flag-Smashers launched their final attack. The episode featured several major developments, such as Walker's new positioning as U.S. Agent and the reveal that Sharon Carter (Emily VanCamp) is in fact the Power Broker (as many had suspected). However, the best and most anticipated part of The Falcon and the Winter Soldier's end was Sam's debut as Captain America, something audiences had been waiting for since the final moments of Avengers: Endgame.

Sam spent all of The Falcon and the Winter Soldier's run trying to decide if he wanted to be Captain America, and the finale saw him take on the mantle wholeheartedly. This, of course, featured a new comics-accurate costume, much to the delight of fans. On the day of the finale's premiere, Mackie took to social media to say, "thank you to everyone who’s seen The Falcon and The Winter Soldier!" He included an excellent black and white photo of himself in his full Captain America costume striking an action pose with the shield. It's enough to reignite fans' excitement all over again. Check it out below.

To properly cap off Sam's journey, the series changed its name to Captain America and the Winter Soldier in the credits. This led many to believe a season 2 is on the way, but it looks like Marvel is taking things in another direction. Hours after the episode debuted on Disney+, Marvel announced Captain America 4 is in development with The Falcon and the Winter Soldier showrunner Malcolm Spellman. Though the studio opted to not say who will star in the film, it' seems certain Mackie will be getting his own Captain America movie.

Though the finale has received some mixed responses, there's no question that Sam becoming Captain America was the most celebrated moment. Time and time again, Sam has proven himself to be Steve Rogers' (Chris Evans) perfect replacement, and it's amazing to finally see him step into the role. With Captain America 4, Sam can really settle into his new position now that the set-up and first mission has taken place. The Falcon and the Winter Soldier was a good start, and now both Mackie and Sam are ready for what's next.
