Marvel is gearing up to drop Captain America 4 and here are some hot rumors popping out on the Internet.
The Falcon and the Winter Soldier, a film from the Marvel Cinematic Universe, signaled the beginning of a new era for a few key Captain America characters. Not only do Sam Wilson and Bucky Barnes enter the next chapter of their MCU narrative, but Agent Sharon Carter also enters.

However, her story does not lead her to heroism; instead, she becomes the Power Broker, a facilitator of the Flag Smashers’ anti-nationalist organization, and is effectively turned into a series villain. The majority of fans were dissatisfied with this new Sharon because she is a cherished figure and because her huge change in morality becomes inconsistent with her character. However, the next Captain America 4 may be able to correct this oversight.
Agent Sharon Carter had previously been a state adversary, but for very different causes. In “Captain America: Civil War,” the former S.H.I.E.L.D. Agent supported Team Captain America by taking Falcon’s wings and Captain America’s shield from the state and returning them to their legitimate owners so they could fight Team Iron Man. Sharon went on the run when the bulk of Captain’s squad was imprisoned for resisting the Sokovia Accords, having settled in Madripoor.

Team Captain was not imprisoned for long; by the conclusion of the Civil War, Steve had freed them. Sharon later becomes the antagonist Power Broker in “The Falcon and the Winter Soldier” after being left in her own ways in Madripoor. The cause for her moral-180 is not stated; it may be due to her enraged feeling at being neglected by Steve Rogers after playing such an important part for Team Captain.
Captain America 4 Updates

Fans were not thrilled with villain Sharon in Falcon and the Winter Soldier due to many reasons. While the agent has previously played a criminal role in Marvel Comics, it was never her own decision; she was always indoctrinated or disabled somehow. However, in Captain America 4, she is not brainwashed; instead, she is appointed as the Power Broker by her agency. This is why people disliked Sharon as the adversary since it was out of line for her.
Marvel Studios seems to have heard the outrage, as it was rumored last year that Sharon’s position in Captain America 4 would be altered from what was originally intended. Instead of becoming the major enemy in the next film, Marvel has cast a different figure to play the villain. Though MCU followers will likely be pleased with this revelation, it does mean Sharon’s position in Captain America 4 will be decreased. Regardless, this probable adjustment provides the film a chance to rehabilitate Sharon Carter in the MCU.
