With Chris Evans saying that Avengers 4 will be his final appearance as Captain America, a lot of fans are guessing that they will have someone else take up the mantle for the future of the MCU. One fan favorite choice is Bucky, and actor Sebastian Stan comments on how different his Captain would be.
Talking to BUILD Series, Stan comments:
"I mean look, you know it would have to be a very different quote ‘Captain America.' It just wouldn't be the same. It would be interesting… in the comic books it was always interesting because there's an emotional turmoil, there was a guilt there that was driving for me, a character, because, because it's Steve's absence. It sort of felt like the guy had to once again carry on this vision that his best friend had for years and what he stood for, and that struggle, have that kinda coming into conflict with someone who's still grappling with their own past and what is the right thing to do now, and if you have a character who's always searching and forgetting an identity and finally gets an identity only to have to lose it again to an idea, then it makes it for the complex take on it, you know what I mean. So if they ever were to explore that it would be a very different, definitely way darker take on the situation."
For now, Bucky's fate is up in the air after Avengers: Infinity War, but it's entirely possible for him to come back somewhere down the line. The Winter Soldier has become a very popular character with MCU fans, and it would be interesting to see how Bucky would be able to carry on Cap's legacy.
Then again, I think it would be more fitting for Falcon/Sam Wilson to take on the role—just like in the comics.
For now, we can catch Sebastian Stan's Bucky Barnes in Avengers: Infinity War.
