This standalone issue ties in with the “DC One Million” mini-series which features the future versions of characters meeting their historic counterparts. Only the future version of Wonder Woman is featured in this story.
She was a member of the Justice Legion Alpha, from the 853rd Century. Like Diana, this Wonder Woman had an unusual birth too, born as a marble statue and granted life by the Goddess of Truth, who was possibly Diana after having ascended to Godhood once again.
She was appointed the protector of the planet Venus, the new home of the Amazons, and worked with the Justice League along with her sidekick Troy, a younger girl likewise made of marble.
