The Winter Soldier, also known as Bucky Barnes, is a super-soldier who was brainwashed by HYDRA, a fictional terrorist organization. He was controlled through a set of Russian codewords that when spoken, put him into a compliant state, ready to receive and execute orders without question.
These activation codewords were first introduced in "Captain America: Civil War" (2016) and are as follows:
"Longing"
"Rusted"
"Seventeen"
"Daybreak"
"Furnace"
"Nine"
"Benign"
"Homecoming"
"One"
"Freight Car"
When these words are spoken in this specific sequence, the Winter Soldier is primed for orders and executes them with no memory of his actions.% polyester, 25% combed ringspun cotton, 25% rayon
