Captain America: Civil War - Ranking The Characters By Screen Time

2. Iron Man

As Captain America: Civil War's main antagonist - and indeed the flagship star of the Marvel Cinematic Universe - Iron Man AKA Tony Stark will undoubtedly be second only to the titular hero in terms of his screen time. He'll be the leader of the pro-registration team, tasked with bringing Captain America down non-lethally - having been asked to do so by the government, as an alternative to them being less merciful. He'll also have a personal vendetta to pursue - the one involving his parents' killer; Bucky Barnes AKA the Winter Soldier. With that in mind, it'll be another action-packed, emotional adventure for Iron Man - one that won't be at all pretty - and he'll barely make it out alive. Uniquely for a movie's antagonist, given his unrivaled popularity, he'll probably have the fans on his side.
