The Winter Soldier

Department X scientists give Bucky Barnes a bionic arm to replace the one he lost. After undergoing hypnotic training, he is used as a secret assassin called the "Winter Soldier." In-between his various covert wetwork missions, he is kept in cryogenic stasis, placing him in suspended animation for months and sometimes years at a time. As technology improves, the Winter Soldier's bionic arm is regularly updated.
