Superman #6

Superman stands front and center in his classic red-and-blue suit, his expression taut with determination as he faces something just beyond the frame — while a shadowy, glowing-eyed figure looms ominously in the green-tinged background. The cover by Ivan Reis and Joe Prado bathes the scene in an eerie kryptonite-green haze, lending real tension to "The Unity Saga Part 6," Brian Michael Bendis's ongoing run on the Man of Steel. It's a striking image that makes clear Superman is caught between a threat behind him and whatever lies ahead.
