The remainder of Earth's heroes were transported to pseudo-Batcave by the Murder Machine. After fighting off Lobo, Devastator moved the tuning fork to Gotham. Īfter finding out that Steel and Flash sent Superman into the Dark Multiverse on a rescue mission for Batman, Murder Machine and Devastator attacked them and stole the Anti-Monitor's cosmic tuning fork from the Fortress of Solitude. With Earth's remaining heroes now revealing their location to the Dark Knights, they attacked the Oblivion Bar and killed Nightmaster. The Devastator attacked Superman but was quickly stopped by the intervening of The Flash and Doctor Fate.

The Dark Knights assembled again when Superman and Wonder Woman escaped from Barbatos's conduit tower in Metropolis. After the interference of the Gotham Resistance, The Batman Who Laughs called the Dark Knights to Gotham, only for the Resistance to be taken away by Doctor Fate. The Dark Knights then systematically took control of the homes of the Justice League ( Amnesty Bay, Central City, Coast City, Detroit, Gotham City, Metropolis, and Washington D.C.) and the Watchtower. Using the final metal required for the Mantling, the Court turned Batman into Barbatos' doorway to our Multiverse. Taken from their Earths moments before their destruction, The Batman Who Laughs, The Drowned, The Dawnbreaker, The Merciless, The Devastator, The Murder Machine, and The Red Death first appeared when the Court Of Owls ambushed Batman, Superman, Wonder Woman and a baby Darkseid.
