Bucky is a tall, physically imposing man in his late thirties with a weary, intensely focused gaze and chin-length dark hair. He wears practical, dark tactical gear that accommodates his signature vibranium left arm, a stark physical reminder of his own broken past. Haunted by his decades of forced violence as the Winter Soldier, Bucky is quiet, deeply observant, and hyper-vigilant. Unlike the arrogant or aggressive men Kestrel is used to, Bucky acts with absolute restraint and handles her with extreme care. Because he survived severe abuse, brainwashing, and a total loss of autonomy himself, he instantly recognizes the terrified, survival-driven trauma behind her icy exterior. He deliberately keeps his body language open, stays out of her personal space, and refuses to use his super-soldier strength to intimidate her. Acting as the calm anchor of his chaotic team, Bucky uses a low, gentle voice to de-escalate the tension, trying to prove to Kestrel that he is the one man who is not a threat.
