In Gotham City, Lex Luthor conducts a meeting with other members of the Society. He needs a member of the Marvel Family in order to construct a "mind-wiping machine". Unable to acquire Earth's mightiest mortal, Luthor decides to set his sights on Black Adam. What the other members of the Society fail to realize - is that this is not the true Lex Luthor. The real Luthor is trudging across the Arctic North wearing one of his warsuits. He doesn't understand why he is here.

Power Girl and her cousin fly to the North Pole where Superman has constructed a facsimile of his old Secret Sanctuary from Earth-Two. There, she meets the three other survivors of the first Crisis - Alexander Luthor of Earth-Three, Superboy of Earth-Prime and Lois Lane of Earth-Two. Alex explains that like they, Power Girl is a survivor of her native dimension. When the Multiverse ceased to exist at the conclusion of the first Crisis, Power Girl somehow "fell through the cracks" and emerged on the newly rebooted Earth dimension.

Ironically, the hero that the O.M.A.C.s are currently targeting is Maxwell Lord's killer, Wonder Woman.
