Marvel Civil War: 21 Predictions For Who Will Side With Who

9. The Winter Soldier (Anti-Registration)

Captain America: The Winter Soldier saw Steve Rogers' old friend Bucky Barnes having been brainwashed by Hydra. As a result - and having been kept on ice since World War II to keep him alive - he fought Captain America as the movie's lead antagonist. However, at the end, he showed signs of remembering who he used to be and, once that happens, he will undoubtedly side with his childhood best friend on the anti-registration side. Having lived for more than seventy years as Hydra's puppet, it will make sense for Barnes to want freedom rather than being forced to register himself as superhuman - and that's regardless of his obvious affiliation with the anti-registration side's leader.
