Fantastic work! I'm looking forward to reading this in detail. In my view, COIE remains the best and maybe only major mainstream comic "event" book that really, really worked.
One question: years later, Power Girl is restored to her origin as Superman's cousin. As I recall, the Psycho-Pirate figures in this. Kara is a refugee from a universe that was destroyed. Later, she discovers another universe with another PG, but it is not her own. At any rate, is Power Girl meant to be a refugee from a universe destroyed during COIE or was she made a refugee during some other universe-destroying event?
