Superman / Batman #48

This unsettling cover for Superman/Batman #48 puts Superman's familiar red-and-blue costume front and center — but something is deeply wrong, as jagged green Kryptonite crystals burst through the Man of Steel's fist and chest while an inferno rages behind him. Shane Davis and Matt Banning deliver a visceral image that raises immediate questions about what's happening to the World's Finest hero in "K Chapter 5: All-American." Part of a larger Kryptonite-focused arc, this 2008 issue promises the kind of high-stakes tension that the Superman/Batman series did so well at making feel genuinely dire.
