The Uncanny X-Men #202

Two massive, purple-helmeted Sentinels dominate this snow-swept 1986 cover, their enormous fists practically bursting off the page while a small band of X-Men — including figures in green, red, and yellow costumes — scramble and fight in the space between them. A glowing pink energy sphere pulses near the feet of one colossal robot as another X-Man in dark clothing stands defiantly at the base, the whole scene carrying that unmistakable sense of desperate odds. John Romita Jr. and Al Williamson's cover work crackles with kinetic tension, and the "Secret Wars II continues in this issue!" banner promises that the Beyonder's shadow looms over everything the X-Men are fighting through.
