Plot

The Psycho-Pirate tells Power Girl how the two of them are the only survivors of a parallel universe and that she came from the Krypton in that universe to its Earth and became a member of the Justice Society of America there before the universes were combined when the Anti-Monitor attacked. The Psycho-Pirate surmises he survived the re-writing of history because he was with the Anti-Monitor and that Power Girl survived because she still has some tie remaining in this new universe. The villain sends Power Girl off to tell everyone what she has learned before the coming crisis.
