Wow what comic was that? I’ve never read it. Was it in Superman/Batman? To answer your question yes. The first instance of Earth 22 was in Elseworld’s Finest: Supergirl and Batgirl #1 written by Barbara Kesel. It’s a 66-page one-shot. The genderbend is done a little differently, instead of a female Clark Kent, Kara Zor-El is the primary Kryptonian superhero. Same with Barbara Gordon. But yeah if you like canon gender bends you’ll love this book.
someone just corrected us that its not earth-22. its earth-11. the point stills stands
Weirdly enough, the Flash of Earth-11 is the main Flash in a KFC promotional comic where the Flashes and Col. Sanders of the Multiverse team up to reassemble the secret recipe of herbs and spices, which has been scattered across multiple realities.
I swear I’m not making it up. You can find it on Comixology.
