Original VA: Scott Porter (alt: Yuri Lowenthall, Ray Chase)

James Buchanan Barnes, also known as Bucky, was Captain America's partner before he was supposedly killed. Captain America fell into the ice and slept for decades until being revived, but so did Bucky, being brainwashed and implanted with a metal arm to become the secret assassin only known as the Winter Soldier. Gone was his upbeat attitude, now he's just a war machine. Even after breaking out of his programming and spending some time as Captain America himself, he is still an incredibly serious person with nothing but the mission on his mind.
