The motley crew of "Doom Metal" sets sail for the cliffs of insanity, captained by Nightwing-or so he thinks! The team fractures, and Detective Chimp reveals the horrible secret wish in his heart. And speaking of hearts, Hawkgirl will stop at nothing to find Martian Manhunter, even if she jeopardizes the League's mission and their souls. Part three of this five-issue tie-in to Dark Nights: Death Metal features the debut of a villain so huge he dwarfs all hope. Enter the Omega Knight.
