The Challengers From Beyond arrive on Earth-43 in a Gotham City plagued by reports of vampires. Splitting up to search for Ray Palmer, Donna finds the staked body of this world's Barbara Gordon who dies just as Donna finds the print of Ray Palmer's Atom symbol on her arm. Attempting to track down the vampire killer that they believe is Palmer, Kyle and Jason are attacked by homeless people who are also vampires, one of whom bites Kyle. Dick Grayson, meanwhile, is the vampire killer and he tracks down the lair of this world's Batman, planning to plunge a stake into his heart. The Challengers track him down as well and try to stop him killing Batman which, in turn, allows Batman to bite Grayson. The pair escape and, as the Challengers leave Earth-43, Grayson is revealed as a new vampiric Robin alongside Batman.
