Bucky Barnes → Supernatural

Role: A former government operative who disappeared after a classified mission and now works independently, occasionally crossing paths with the Winchesters.

Personality: Quiet, guarded, observant, dryly funny, and extremely loyal once trust is earned.

Friend: Dean Winchester — minimal emotional conversation, maximum mutual understanding.

Partner: Jody Mills — mature, capable, and independent. She wouldn’t treat Bucky like someone who needs fixing, and he’d respect that she doesn’t scare easily.

Biggest flaw: He assumes he has to handle everything alone.

Reputation: The mysterious guy who always seems to know more than he says.

Signature: Old motorcycles, black jackets, coffee, motel rooms, and disappearing before anyone can ask too many questions.

What stays: His loyalty, restraint, dry humor, protective instinct, resilience, and complicated relationship with his past.
