Professor Xavier and the X-Men #13

The original X-Men in their classic yellow-and-blue uniforms clash in full force on this energetic November 1996 cover from Steve Geiger, whose pencils and inks capture Beast, Angel, Marvel Girl, and Cyclops locked in a chaotic, hard-hitting brawl against a snarling foe at the center of the action. Subtitled "Trespassing," the image crackles with that early-team energy, wings sweeping dramatically across the composition while claws and fists fly in every direction. It's a lively, well-constructed piece that should appeal to anyone who loves seeing Xavier's original students cut loose.
