The Winter Soldier was the villain in the second installment of Captain America. But towards the end, (SPOILERS) he saves Steve Rodgers from the crash of the SHIELD Helicarrier. But how I think he's gonna be in Civil War? I personally think he's gonna be a surprise. I think he won't be recognized as much as the other characters. The Winter Soldier is kind of a character, that I feel, is not shown as much in the media side of Marvel. Winter Soldier was only brought in through comics. And I don't know a lot about the Winter Soldier comics.
