MCU: 10 Characters Most Likely To Die (And The Movies They'll Die In)

10. Thanos (Avengers 4)

Why He's Likely To Die: Currently, we don't know anything about Thanos' role in Avengers 4, other than that he has one.

It's assumed that the movie will involve all sorts of non-linear jumping around in space and time, with our heroes searching for a way to reverse that deadly genocidal snap. Should they succeed - or come close to succeeding - Thanos will probably be quite annoyed with that, and this could be how he enters the fray.

Infinity War made it clear that he will stop at nothing to achieve his goals - he even sacrificed his own daughter as a means to an end. So if the Avengers do reverse the snap, you can be damn sure that Thanos will do everything in his power to make it happen all over again, or even stop them before they can undo it in the first place.

Simply put, he's too powerful and driven to be left alive. If he's locked up, injured, or otherwise taken out of the game in a non-deadly way, he's just going to come back later and cause more trouble. Killing him is the only way to stop him for good.

Plus, while his popularity might turn him into a recurring threat, he's already reached the peak of villainy after literally destroying half the universe. What else could he possibly do after that?
