In the Marvel comics, how is Bucky Barnes alternatively known?

I love comic books!! Miss the back page ads for Sea monkeys. I would envision them riding the sea horses and protecting their realms. Those ads with the skinny guy getting sand kicked in his face was hilarious. Ahh for the old days...

Which is the film called Untitled in the blurb

I’m just looking at him now in Avengers: Endgame
