9. The Fall Of The First Class
X-Men: Days of Future Past features a huge cast of characters, so it was inevitable that not everyone could be brought back and fitted into the story. You may have noticed that when Mystique visits Bolivar Trask’s office she looks through a number of files which contain images of the mutilated corpses of Angel, Azazel and more. During a future set scene of the movie, we see one of the Sentinels use Emma Frost’s powers, hinting that she too was a victim of the man who created the mutant hunting robots. It’s a clever and satisfying way of explaining where many of the X-Men: First Class characters are, and while it’s a shame that we won’t see many of them again down the line, it does at least sound as if some other familiar faces will make a return in X-Men: Apocalypse!
