Earth-Three’s future is ruled by the Cabal of Super-Criminals, but for the first time a hero might just challenge them! And it will take a voyage through time and to a parallel universe to transform Urthlo 5, the last descendant of Alexander Luthor, into the Defender! Guest starring the Faultless Five, the Crime Syndicate of America, and the Adult Legion of Super-Heroes!
In the alternate future timeline of the Adult Legion of Super-Heroes, the good fight continues with new members such as Lexor Man and Mr. Mxyztic. But even grown-up Legionnaires can be fooled, as shown when they are manipulated by Lightning Lord and Saturn Queen into letting them go free. Meanwhile, a new threat is on the horizon when a rogue Coluan with thirteenth-level intelligence who calls himself the Computyrant begins reassembling the Legion of Super-Villains!
