X-Men Apocalypse Art Pits Two Heroes Against Each Other

In this newly released concept art for X-Men: Apocalypse, classic heroes Cyclops and Jean Grey are defending themselves against a flying assailant, but if you take a closer look that opponent appears to be Storm.

Like Cyclops and Jean Grey, Storm is a veteran member of the X-Men, so to see her fighting Xavier's team is very concerning. The team will be put up against Apocalypse, who will assemble his four horsemen in the film. Will the movie flip the story on its head, and make Storm a villain?
