x-men, apocalypse, x-men: apocalypse, jennifer lawrence, james mcavoyThe first full trailer for "X-Men: Apocalypse" dropped this morning, and it's bursting with new characters, explosive action sequences, and a feeling of dread that can really only be applied to a film with "Apocalypse" for a subtitle.

The literally-dark mood certainly suggests the end of days, and the clip begins with Jean Grey (Sophie Turner) waking with a start, telling Professor X (James McAvoy) that she "saw the end of the world," littered with death. X assures her it was just a dream, but it turns out to be a very real nightmare soon enough.

Apocalypse (Oscar Isaac), believed to be the first-ever mutant, has awakened from an ancient sleep, and makes quick work of taking over the minds of several mutants, harnessing Psylocke (Olivia Munn), Storm (Alexandra Shipp), Angel (soon-to-be-Archangel, Ben Hardy), and Magneto (Michael Fassbender) into his own version of the Four Horsemen of the Apocalypse. Led by Raven (Jennifer Lawrence) and Professor X (who we finally see bald, at the end of the clip), the rest of the X-Men must fight back against Apocalypse's power grab -- and assured destruction of the rest of the world -- or risk Jean Grey's premonition coming true.

"This is war," Raven declares.

Game on.
