- Synopsis
- Conner-Superboy arrives where an alt-Superboy and alt-Knockout believe he's an agent of Black Zero. In a fight, alt-Knockout slams him, which activates his hyper-jacket. He arrives at an alt-JSA who are also paranoid about Black Zero. Stormguards attack and he tumbles through MANY realities. When his hyper-jacket glows nuclear, another Superboy hurls it away to explode. Clark-Superboy takes Conner-Superboy home to the Kents and finds that though they look alike, they have different fingerprints. Meanwhile, Mickey Cannon and Colonel Winterborne decide with Superboy gone, they must replace him.
