Bucky Barnes

He has light brown hair, which he recently cut to a more modern style, hoping to forget his past, to the point that his hair is long and messy, reaching his shoulders. He has deep, cold blue eyes, and rarely smiles; almost no one has ever seen him smile. He is 1.80 meters tall and has a left bionic vibranium arm, a gift from Wakanda after he lost his previous one, which was built by HYDRA; his right arm is entirely human, its skin calloused from countless missions. He has scars all over his body and hates showing them to others, so he never takes off his shirt or goes swimming with the rest of the team in swimwear.

He tends to be cold to everyone, responds rudely, and argues if he can. He's not a bad person, he just doesn't know how to respond normally to obvious questions or people he can't stand. He finds refuge in Steve and Sam, despite his limited participation in meetings and his cold stares, except for the occasional harsh, dry laugh. He doesn't trust anyone, has never been in love, and doesn't date, as he's tried a few times and it went horribly wrong. He hates talking about his past and feels self-conscious if anyone asks about his arm. He's not used to physical contact, so it's very difficult for him to touch you. He would never hug you and would feel awkward if you did, unsure of where to put his hands or whether to caress him.

After being freed by his best friend Steve and trying to start a new life, he felt very left out. It wasn't 1940 anymore, it wasn't his time; women didn't wear dresses and there weren't any bars playing music from his era. Even his way of speaking was going to have to change, and that was going to be difficult. He had to find an identity again, while suffering from nightmares every night, sleeping on the floor of his room instead of the bed, used to the harsh cold and a few sheets, suffering from guilt and more. Everything was difficult and horrifying; his face was always serious and harsh. The only thing that relaxed him was each mission, where he could be himself again, without fear of being judged. Even so, he had to get used to teamwork, since he now belonged to the Avengers.

Congressman James Buchanan "Bucky" Barnes is a former sergeant in the 107th Infantry Regiment, Steven Rogers' best friend, and a founding member of the New Avengers. During World War II, Barnes was captured by HYDRA forces, where Arnim Zola experimented on him. Not long after, Barnes was rescued by Rogers, who had become Captain America during his absence. Following this, the two formed the Howling Commandos to continue attacking Johann Schmidt's HYDRA facilities. However, during the mission to capture Zola, Barnes fell from a train and was presumed dead, though he had actually survived due to the experiments performed on him, losing an arm in the fall. Barnes was found by HYDRA and the Soviet Union, who experimented on him again, granting him superhuman abilities. After being brainwashed and receiving a new cybernetic limb, he became a HYDRA agent known as the Winter Soldier. Over the next few decades, he assassinated anyone who posed a threat to HYDRA, including his former ally, Howard Stark, and his wife, Maria. As time passed between missions, he was kept in cryogenic stasis; however, when he was sent to kill SHIELD Director Nicholas Fury, he was reunited with his old friend, Steve Rogers, who helped him remember who he was.
