Justice League 3001 (formerly known as Justice League 3000) has always featured a revolving door of superheroes.

The trippy series finds a corporation of the distant future recreating the Justice League of today using DNA samples from the likes of Superman, Batman, Wonder Woman, Green Lantern and the Flash. Not everything is quite what it seems — but to say any more would be getting into spoiler territory.

As the series has unfolded, more superheroes of yesterday have been cloned and have joined the team, while others have left. After issue #15, the comic jumped forward by a year and renamed itself Justice League 3001. The ever-shifting lineup continues in this "second year" of the series, and as of this January, it's going to morph into an all-female team.

Creator Keith Giffen told Newsarama that it wasn't done in order to conform to the industry's demands for more diversity, or because all the cool kids are doing it. Instead, it's "just the way it shook out."

"Some of the characters just seemed more interesting or more appropriate for the kind of stories we're trying to tell," Giffen continued, expanding on his thinking. That girl-powered lineup is likely to include 3001's cloned versions of Wonder Woman, the female Guy Gardner Green Lantern, the female Flash and Supergirl. But Supergirl is an exception to the rule — she's not a clone, she's the real deal from the planet Krypton.

In Newsarama's interview, Giffen also noted that his intention is for the comic to continue changing its title every 12 issues. So after Justice League 3001 reaches issue #12, it will become Justice League 3002, and so on.
