A new Superwoman named "Laurel", is a female version of Superman from a parallel Earth (now identified as Earth-11), appeared for the first time in "Superman/Batman" [Issue #23 and Issue #24]
In December 2007, Superwoman and Batwoman were featured in "Countdown Presents: The Search for Ray Palmer: Superwoman/Batwoman" #1.
She also appeared in the Search for Ray Plamer series during Countdown. If you can check that one out their are also female a female atom and batman PLUS a male "Wonder Woman" and Black Canary. I am so glad someone else is a fan of the Alternate Earths. Although I am a Earth 9 guy.
