Batman Superman #5

"The Batman Who Laughs has unleashed his Secret Six! Now these infected heroes threaten to spread their dark infection across our world, and the only thing that might stop them is the combined might of the Dark Knight and the Man of Steel. If they fail, the planet will become the seed that grows a new Dark Multiverse-heroes will fall, villains will rise, and a new era dawns for the DCU in this explosive first arc finale that leads directly into Year of the Villain: Hell Arisen #1!"
