Superman #22

John Byrne's cover for Superman #22 (1988) is a genuinely unsettling image: a menacing, bird-masked figure in black and green looms toward the viewer, thrusting forward a glowing box that holds what appears to be a fragment of Kryptonite — while speech bubbles declare, "You're responsible for the deaths of a billion beings — for that you must die!" The all-green color scheme gives the whole composition an eerie, poisonous intensity that makes it hard to look away. With Byrne handling writing, art, and inks himself, "The Price" looks like a story that takes Superman's greatest vulnerability and weaponizes it with cosmic stakes.
