⓵ Backtagging: Yes, always, onwards forever.
⓶ Threadhopping: Go for it.
⓷ Fourthwalling: Bucky knows he exists in comic books: the original 1940s Captain America comics exist in the Marvel Universe as propaganda for the war effort. His secret identity and general backstory are also well-known in his universe (including that he was once a KGB assassin)— so I don't mind if you want your character to know this stuff. I'd prefer to stay away just flat-out telling him he's fictional, though.
⓸ Alternate Universes: I play from 616¹ continuity but I like threading with canonmates from other universes. I default to not reconginzing most AU canonmates right away but “feeling” a connection nonetheless. I'm also happy to just go with the flow of a thread, if you want to do it another way!
⓹ Offensive subjects: Bucky's canon involves brainwashing, violence, and a more than usual amount of Nazis. Older comics also include period-typical racism & sexism. Please let me know if there's something you don't want to be tagged with.

⓵ Shippy Stuff: I ship Bucky/Natasha, and I'm open to other pairings if there's chemistry. I don't play smut.
⓶ Fighting: Character is from a superhero comic, fighting is what he does, feel free to throw the first punch. Major injury and death is something I prefer to discuss beforehand, but feel free to PM me.
⓷ Psychic stuff: Bucky's been severely brain-scrambled in the past, and has also had SHIELD put in mental safeguards from to make his mind harder to mess with. A powerful telepath could likely get through all of that, though, do what you will with all that.
