"You have a metal arm? That is awesome, dude!"
Spider-Man to Winter Soldier[src]

Winter Soldier's Prosthetic Arm was a cybernetic implant attached to the Winter Soldier's body to be used in place of his missing left arm.

HYDRA's scientists turn Bucky Barnes into the Winter Soldier.

Following Bucky Barnes' fall from Arnim Zola's speeding train, he suffered injuries that included the loss of his left arm. The prosthetic arm was only a portion of the reconstruction efforts HYDRA used in turning Barnes into their deadly assassin. The construction of the arm presumably took place in secret HYDRA facilities in the Soviet Union, following World War II. With the communist red star imprinted on the arm, the brainwashed Barnes eventually became known as the Winter Soldier.

"He's fast. Strong. Had a metal arm."
Captain America about the Winter Soldier[src]

During his fight with Captain America in Washington, D.C. following his attempt to kill Nick Fury, the Winter Soldier's arm was damaged by Captain America's Shield. The arm, which is at least partially mechanical, was repaired later by HYDRA doctors in the Ideal Federal Savings Bank, a HYDRA facility run by Alexander Pierce. Barnes later used the arm to rescue Rogers from drowning in the Potomac River.[1]

Barnes used his prosthetic arm to defend himself from Tony Stark's allies at the Flughafen Leipzig-Halle. Intercepted by Spider-Man, Barnes found the strength of his arm matched when an attempt to land a strike was countered by the enhanced youth who casually voiced his awe that Barnes had a metal arm. Later, when the two Avengers factions met in a skirmish, Barnes was engaged by Black Panther, who quickly overpowered him due to his use of the vibranium suit, Panther Habit.[2]

Battle of the HYDRA Siberian Facility

The arm was destroyed by Tony Stark's unibeam when Stark was manipulated by Helmut Zemo to attack Rogers and Barnes. The arm was not replaced even after the battle, and the remaining shoulder of the arm was removed before Barnes chose to be frozen until a cure for his brainwashing can be found.[2]


The bionic arm gives him strength superior to that of Captain America. The Winter Soldier was able to rip open a S.H.I.E.L.D. armor SUV, rip apart Sam Wilson's EXO-7 Falcon, and smash concrete by punching it. With his bionic arm supporting his already-enhanced natural strength, the Winter Soldier was able to overpower Captain America in a fight.[1]

The limits of the bionic arm's strength were realized during the Avengers Civil War. While the arm was stronger than a natural one, it was not as flexible. This was seen when the Winter Soldier found himself matched by Spider-Man, an enhanced youth, who was able to counter his blow due to his superhuman strength and bend back the appendage with ease. The arm was later overpowered by the Black Panther whose vibranium suit, the Panther Habit, allowed him to push back the force of the bionic arm while exploiting its limited mobility. The arm proved inferior to the gauntlets of the Mark XLVI as Stark was easily able to counter it before disintegrating the limb with his unibeam.[2]
