10 Past MCU Moments That Will Mean Something Big In Phase 4 And Beyond

10. Red Guardian Vs Captain America - Black Widow

During the events of the first proper phase 4 MCU film Black Widow, there’s a running gag surrounding the character of Alexis. He claims at multiple points in the movie that he fought Captain America during the Cold War, something that should have been impossible considering Steve Rogers was frozen during this time.

However, even though this is played for laughs, there’s no actual payoff or confirmation that what the Red Guardian is saying here is a lie or not, and with The Falcon And The Winter Soldier confirming that attempts at new super-soldiers have been made, there is a possibility that what Alexis is saying here may be the truth.

There are multiple evil versions of Captain America in the comics, including characters like William Burnside, who looks and acts precisely like Steve Rogers and takes the hero's place post World War II. With this in mind, it's possible that Alexis didn't fight the Captain America, but possibly a Captain America.

This may be a joke for the movie and nothing more, but it’s equally as possible that Marvel is foreshadowing something much bigger and that we’ll see develop in future projects.
