It's no secret that when "X-Men: Apocalypse" hits theaters this month that Storm will be on the side of the enemy. Her character will somehow be manipulated by Apocalypse into becoming one of his horsemen, which means she'll be using her weather-bending powers against the X-Men.
In the featurette below, the actress who plays Storm, Alexandra Shipp, describes how Apocalypse (Oscar Isaac) is able to tap into Storm's dark side. The power that he gives her will amplify her abilities, which will make her a powerful adversary for Xavier's X-Men to fight.
Directed by Bryan Singer and starring James McAvoy, Michael Fassbender, Jennifer Lawrence, Sophie Turner, Olivia Munn, Oscar Isaac and many, many more, "X-Men: Apocalypse" arrives in theaters May 27, 2016.
