7. Captain America Is Resurrected (After Being Killed In Civil War)
It goes without saying that this particularly shocking fan theory only works if Captain America actually dies during the events of Civil War - an event which seemed unlikely at first but also one that fans just can't seem to stop themselves thinking will happen. In the wake of Captain America's death, then, what could be more shocking than The First Avenger meeting his doom only for Steve Rogers to wind up being brought back to life during the events of Infinity War? And right at the end of the first part, no less - ensuring that the internet has something insane to talk about in the space between films. "How the hell would they do that?" you're wondering. Well, according to the fan theory, the answer is as easy as: "With the Infinity Stones, duh!" This might seem a little rough around the edges as far as theories go, but it does ensure a few things. Firstly, it still lets Marvel kill off Captain America, granting them their huge and franchise-shattering death at the end of Civil War. Secondly, it gives them Captain America back. Thirdly, it would offer Infinity War: Part I the chance for a totally nutty cliffhanger.
