After years of epic battles, the Dark Knight finally finds a way to cure the twisted mind of his archenemy. The Joker...is now sane. The Clown Prince of Crime has now changed his ways, fighting for good in Gotham City, and it may just cause Batman to go over the edge of his own sanity.
The event that asked, "What happens when evil wins?" is collected in an omnibus edition that features every tie-in miniseries and chapter, as Superman, Batman and the Justice League must face this reality when Darkseid and his followers win the war between light and dark!
The Red Death. The Devastator. The Merciless. The Murder Machine. The Drowned. The Dawnbreaker. And the Batman Who Laughs. These evil Batmen-twisted mirror images of the Dark Knight-have been unleashed upon Earth-0 and the Justice League with only one thing on their minds: total devastation.
