Now the heroes of the Justice League of America - including a new Flash and a new Wonder Woman - must struggle to stop a champion gone completely out of control.

1997 : From his exile in the Phantom Zone, Superman watches as the 20th century nears its close and a new hero makes his debut in Gotham City. Thogh invisible and intangible, the Man of Steel may still be Knightwing's only hope, a ghost of a chance that super-heroism can survive in a world without a Batman.
