8. The Winter Soldier's "Central" Role
Only briefly mentioned in Age of Ultron, fans are hoping that the hunt for Bucky will be a major part of Captain America: Civil War despite the fact that it's shaping up to essentially be another Avengers movie. Well, it's been widely reported that The Winter Soldier will have a pivotal role in the threequel, and is actually the catalyst for the war between the heroes. Captain America and Iron Man are apparently on opposing sides when it comes to how Bucky should be dealt with. Steve wants to help his former sidekick, while Tony believes he should be stopped because he's a potential threat. Why is he so passionate about this? Well, Iron Man learns that it was The Winter Soldier who years ago assassinated his parents.
