Falcon & Captain America:

Steve Rogers explained why he chose Falcon as the new Captain America before he time traveled at the end of Avengers: Endgame. In the lead up to the culminating Marvel Cinematic Universe film, one burning question fans had was what the future held for Captain America (Chris Evans). Many thought he could die saving the day, but he instead got a happy ending as he went back in time to grow old with Peggy Carter (Hayley Atwell). The moment served as a great closing to Steve's story, but then left the world without a Captain America.
