Jessica Chastain’s as-of-yet unidentified villain in Dark Phoenix will battle all members of the X-Men at once. Her character is one of many mysteries surrounding the follow-up to Bryan Singer’s X-Men: Apocalypse in 2016. 

Following the tease at the end of X-Men: Apocalypse, the latest entry in the X-Men franchise will see a dark and dangerous cosmic force manifest within Jean Grey (Sophie Turner), causing her to spiral out of control. As a result, the mutant heroes will not only have to battle one of their own, but a race of aliens seeking to control her powers. X-Men stories have faced criticism in recent years, with even the comic-book characters lamenting the repetitive nature of their stories, and the first trailer for Dark Phoenix only exacerbated those cries, with many claiming that it feels too similar to The Last Stand. Still, many remain hopeful, especially following the news that Dark Phoenix will draw from the popular “Secret Invasion” storyline.
