Oscar Isaac has the X factor…

20th Century Fox and Marvel Entertainment have released a new featurette for next month’s X-Men: Apocalypse that appears to confirm that the 37-year-old Guatemalan and Cuban American actor’s mysterious new villain is definitely the first mutant to walk the Earth. And, it also reveals more about what Isaac’s character can do when he meets other super-powered beings.

“He’s all powerful and he magnifies all of [the Horsemen’s] powers,” Michael Fassbender (Apocalypse‘s Magneto) explains at the opening of the Four Horsemen teaser video. “He’s decided to take judgment on the world, so he’s gathered a team of mutants to wipe out the human race.”

This mission statement helps make sense of Apocalypse’s declaration from the last trailer, repeated at the end of this video: “Everything they’ve built will fall — and from the ashes of their world, we’ll build a better one.” But who is the “we” he’s talking about: mutants, or just his followers?

Knowing that Apocalypse can increase mutants’ powers suggests that the scene where Professor Xavier (James McAvoy) says, “I’ve never felt power like this before…!” — also repeated in this video — could refer to either Xavier responding to Apocalypse’s powers, or having his own powers increased by Apocalypse for some reason.

“They’re very powerful … the whole world is at stake,” adds Olivia Munn, who plays another of the Horsemen, Psylocke.
