When Alexander Luthor assembled several different DC Superheroes and attached them to the Anti-Monitor's corpse, he began to recreate the Multiverse that was destroyed in the Crisis on Infinite Earths. His goal was to find the "perfect" Earth, where he and his cohorts could live in peace.

When Mr. Mind discovered this new Multiverse, he planned to feed on its energies -- histories, time-space, intelligence -- until nothing was left. Rip Hunter, Booster Gold and his ancestor Daniel Carter set off to stop him. However, in their battle, the entire Multiverse was left changed. The previously identical 52 worlds were now all unique from one another. Currently only several have been documented.

Currently Documented Multiversal Worlds

=================================

• EARTH-2 -- The world of a new and unique Justice Society, where apparently Power-Girl and Superman are missing. Possibly the home of Kal-L and the Power-Girl currently residing in NEW EARTH.

Pre-Crisis Multiversal Worlds

=================================

Before the Crisis on Infinite Earths, there were many (hence "infinite") versions of the Earth scattered throughout the Multiverse. The DC Multiverse first appeared in The Flash #123 when Barry Allen (Flash) found himself in another universe that was separated from his own by being on a different vibrational frequency. This world came to be known as Earth-Two and was populated by the heroes of the "Golden Age" of comics (the 40's and 50's). After this, more worlds were found, and then even more, until finally DC decided it was time to put an end to the expansion of the Multiverse. As was mentioned before, the other worlds were destroyed during the Crisis, but here is a list of the known Earth's before they were lost.
