Superman: The Man of Steel #37

Part of DC's 1994 Zero Hour crossover event, this issue — cheekily subtitled "Bats!" — delivers one of that era's most striking cover images: Superman stands braced and defiant at the center while a swirling mob of Batman variants closes in from every direction, capes and cowls multiplying into near-infinity around him. It's a wonderfully disorienting visual that captures the timeline chaos Zero Hour promises, rendered with real energy by cover artists Jon Bogdanove and Dennis Janke. Louise Simonson, Bogdanove, and Dennis Janke bring the same creative team inside for "Countdown to Zero!," making this a tightly unified package from a memorable moment in Superman's history.
