Fox Home Entertainment gave Fansided an “exclusive look” at lecturer Mystique’s coursework for Xavier’s School for Gifted Youngsters. It details the history of En Sabah Nur aka Apocalypse (played by actor, Oscar Isaac), describing how the ancient mutant can amass power from other mutants, while also enhancing their superhuman gifts.
Since it’s an exclusive, I don’t want to post all the material here; you’ll have to click here for that. Below is a preview, which shows that En Sabah Nur’s threat cannot be understated.
