Flash #215

The cover by Howard Porter and John Livesay pulls no punches: Green Lantern and the Flash square off against Green Arrow and Hawkman in a tense four-way confrontation, with a fifth hero — appearing to be the Atom or Captain Atom — visible in the background, hinting at a fracture running deep through the Justice League's ranks. Bannered as an Identity Crisis tie-in, this December 2004 issue carries the weight of "The Secret That Split the Justice League!" right on its cover. Geoff Johns, Porter, and Livesay deliver what looks to be one of the most charged teammate-versus-teammate showdowns of the era.
