Chameleon Boy infiltrates Imperiex's ranks as Persuader. But something goes horribly wrong.

The Legion must face Imperiex in final battle... while a traitor lurks in their midst.

After eliminating Imperiex, Brainiac 5 takes over his army and plans to conquer the universe. With Superman presumed dead, the other Legionnaires must stop him before it is too late.
