The Incredible Hulk #298

Kevin Nowlan's cover for issue #298 sets a genuinely unsettling tone, depicting the green Hulk locked in a ferocious struggle with a looming, purple-hued monstrous figure whose clawed hands and snarling face dominate the upper half of the image — a dreamlike, almost surreal battleground of floating orbs surrounding them. The title "Sleepwalker!" hints that this August 1984 confrontation from Bill Mantlo and Sal Buscema may be as much a battle of the mind as of brute force. It's a striking, psychedelic piece of mid-'80s Marvel that captures the Hulk at his most ferocious and vulnerable all at once.
