WARNING: The following article contains major spoilers for Justice League #21, by Scott Snyder, Jorge Jimenez, Alejandro Sanchez and Tom Napolitano.

As teased in the final page of Issue #20, Scott Snyder and Jorge Jimenez's Justice League #21 brings us an all-out brawl between Superman and his (possibly evil) counterpart from the future, and CBR has the exclusive preview of the first round between the Men of Steel.

Though the League currently trusts the Superman of the future and his teammates, readers know there's something off about the team. Not only do they apparently control all of reality from their base in the Sixth Dimension, everything seems just a little too perfect to be true. That suspicion seems to have turned out to be correct as Justice League #20 set the stage for Batman and the rest to learn the truth when Hawkgirl and Martian Manhunter's son telepathically pleaded with the younger versions of his parents not to trust anything they were being told.

In addition to the Sixth Dimension Superman stranding his younger counterpart on a sunless planet, CBR's preview shows J'onn and Kendra begin to share that information with the rest of their teammates. But while this should be an easy sell, even Batman has been completely taken in by what he's learned of the future, which includes a near-perfect Gotham City, and his adopted son, Dick Grayson, carrying on the legacy of the Bat.

Check out the full preview, along with the issue's solicitation text, below. Justice League #21, by Scott Snyder and Jorge Jimenez with covers by Jimenez, Jae Lee and Jone Chung, arrives in stores Wednesday, April 3.
