Spinning out of the pages of Dark Nights: Death Metal, Nightwing's on a mission to free the Legion of Doom from Perpetua's clutches, and he's formed his own Justice League to do it! Starfire, Cyborg, Hawkgirl, and Detective Chimp team up to fight their way through an Earth twisted by the Dark Multiverse, but they'll need one more to get the job done...none other than Lex Luthor!
