X-Men Apocalypse: 11 Best Moments
4. The Danger Room
The movie's final scene has Mystique training the new X-Men recruits in a hanger-type room in the bowels of the X-Mansion, all while Xavier watches on with curiosity.
As it turns out, however, the team are actually inside the Danger Room, as the movie concludes with some Sentinels materialising and attacking the team within the controlled environment.
The Danger Room is of course an iconic X-Men locale and to date has only appeared in X-Men: The Last Stand, which has since been obliterated out of continuity.
Though we didn't actually get to see the fight sequence itself, it was still a fun little tease, and made it clear that the new X-Men team will surely be a well-oiled machine by the time the next film rolls around.
