Holly and Harley, powerless now they have returned to Earth, decide to return to Gotham while the Challengers take Karate Kid and Una - freed from the OMACs control - to the JLA to ask for help. When they arrive, though, the JLA has no idea who they are and Firestorm teleports them away as they quickly realise that this world has no memory of them. They fly to Cadmus where they find Jimmy, Forager and the Hairies waiting for them along with Harley and Holly who have also realised they're not remembered. Jimmy helps them gain access to Cadmus and they are met by Dubbilex who allows them to explain why they have arrived but before they can help Karate Kid, Dubbilex proclaims him dead.
