Fullmetal Badass: a.k.a Bucky Barnes
In which Bucky pranks Sam, pisses off Tony, trusts Natasha, doesn't trust Wanda, forms an unexpected friendship with Clint, almost kills Thor, hates T'Challa, and of course, loves Steve.
AU where Bucky lives in the Avengers Tower with everyone else. Set before Infinty War *sob* because the events of the film were painful to watch. I saw it the day after it came out and I can't shut up about it.
