Professor X
The last on this list, Professor X is the leader of the X-Men – the teacher who helps all the young mutants control their powers. In the original trilogy, Patrick Stewart brought him to life, while James McAvoy took the role starting with First Class.
It can be said that his story arc is much more interesting in the new trilogy, since it shows all of his weaknesses – in Days of Future Past he has to face his own fears and become who he was supposed to be from the first place.
The trailer shows him in even more interesting scenes. In one of them, he can walk again and he engages Apocalypse in hand to hand combat. This means that he either took the serum again, either that the fight takes place in his mind (he is losing, by the way). The other one shows him in awe at the tremendous power displayed by Apocalypse – in a way, this scene may have something to do with him losing his hair.
As James McAvoy said, the character will literally pull his hair off at one point in the movie. Is it because he was forced to do something/anything by Apoc? We have no clue – but it surely seems that he will also be tempted by the First Mutant.
