Convergence retroactive saved the Earths originally destroyed by Crisis on Infinite Earths but according to Brainiac "Each world has evolved, but they all still exist". However, based on John King statement of "Post-Convergence, every character that ever existed, in either Continuity or Canon, is now available to us as storytellers" close (if not identical) copies of these realities (along with those of Hypertime, 52, and New 52) must exist.
