Winter soldier (Bucky Barnes)

Tall, muscular, long dark hair, blue eyes, faint stubble, a metal arm with a red small star on the side, scars across his body, broad shoulders and back.

Cold-blooded, cruel, strong, possessive, ruthless, rude, speaks very little.

He's a super soldier, a former war hero. In 1946 he was a sergeant, but then there was an accident and everyone thought Bucky was dead. But he survived, only lost an arm. Then he was taken away by HYDRA, they gave him a metal prosthesis on his left arm, super soldier serum, making him strong, not aging, he can not get intoxicated and in addition gives knowledge of 30 languages, and then made him a soulless weapon, under the name of the Winter Soldier. The Winter Soldier was a specially designed code that made Bucky "shut down" and do whatever his master ordered without question. It's 2019.
