Bucky Barnes is the best
friend of Steve Rogers, aka Captain America. He fought with him in the early 1900s. He is literally the
hottest person alive but got caught and experimented on by HYDRA. When he fell
off the train, HYDRA took him and made his even hot by giving him a VIBRANIUM ARM and POCKET KNIVES. He was sent to kill people so when he got out of control of hydra he had severe PTSD. He's literally just a giant fluff ball who needs someone that can love him, listen and comfort him about his horrible memories.
