Namor, the Sub-Mariner #5

Against a sky burning red with smoke and flame, a silhouetted Namor soars over a devastated cityscape — a striking, moody image that immediately signals serious trouble for Marvel's First and Mightiest Mutant. Floating alongside him are the alarmed faces of several supporting characters, including a helmeted figure, hinting at a wide cast caught up in whatever catastrophe is unfolding below. John Byrne's clean, dramatic linework gives issue #5 of this 1990 series a real sense of scale and urgency, and the story title "All the Rivers Burning!" promises the action lives up to the cover's ominous promise.
