After Crisis on Infinite Earths (1985), there was no Multiverse. Just the DCU. Then in 2005-2006, it came back during and after Infinite Crisis. So in the time between the crossovers how could we have "alternate dimensions"? I remember reading the Teen Titans/Legion Special (November 2004) where The Persuader uses his atomic axe to bring in alternate versions of the Fatal Five from "alternate dimensions". Most people lump alternate dimensions with parallel dimensions, universes, earths. So my question is if there wasn't a Multiverse, and DC had abandoned/disavowed the Hypertime concept, where did all the alternate versions of the Fatal Five come from? Did Geoff Johns just say "screw it" and scrapped continuity? Or is it just sloppy editing on DC's part at the time?
Just curious to get anyone's thoughts on this?
