I hope Bucky keeps some of that menacing-vibe he had in Winter Soldier. Might be my favorite MCU movie, then he got neutered in Infinity War and Endgame.
It's over breh. The menace went away the moment he became "Bucky".
He's always a tweener or anti-hero in the comics though. By the end of this they should either put him on ice or have him at odds with the main heroes again so he can get a little of that mystique back.
