Watch The Post-Credits 'X-Men' Scene From 'The Amazing Spider-Man 2'

Jennifer Lawrence rocks a uniform well.

Audiences that stuck around until after the credits of "The Amazing Spider-Man 2" were treated to a special look at the next adaptation of another Marvel Comics property.

That clip from "X-Men: Days of Future Past" is now online (via IGN) and features another good look at Jennifer Lawrence in action as the shape-shifting Mystique.

In the preview, a young William Stryker arrives on an army base to collect a number of mutants, including Toad (Evan Jonigkeit) and Havok (Lucas Till). What Stryker doesn't count on is Mystique hiding under the skin of one of men present in the bunker.

"X-Men: Days of Future Past" opens in theaters on May 23.
