The Justice Lords hail from an alternate universe where the Justice League™ decided to enforce law and order through any means necessary. Years ago, the Justice League™ defeated them, and Wonder Woman™ returned to their world with them to make sure they stayed in check. But something went wrong. Now, Wonder Woman is back in the world of Batman Beyond™, and Superman™ and Bruce Wayne™ sense that she's hiding something. As Terry McGinnis™ takes a dangerous trip to the Justice Lords' world to find out Wonder Woman's secrets— and encounters a version of himself whose life took a very different path—the Justice Lords return to our Earth in search of Wonder Woman.
