Superman and Quex-Ul, as “Charlie Kweskill”, watch helplessly from the Phantom Zone as General Zod, Jax-Ur, and their Kryptonian cronies attack the Earth. They throw the Justice League satellite out of orbit, with many of the Leaguers aboard. They smash communications satellites, which causes an exchange of atomic missiles, stopped only by Supergirl and Wonder Woman.
Green Lantern’s power battery is stolen, and he is rendered unconscious by the Zoners when he pursues them, with his power ring charge running out shortly afterward. Supergirl tells Batman what has occurred, and then goes to the Fortress of Solitude, where the Zoners have already smashed open the door and destroyed the Phantom Zone projector and viewer. Supergirl engages General Zod, Jax-Ur and Kru-El in battle and is defeated.
Nam-Ek, who had been badly burned and convulsed by Az-Rel and Nadira, uses his Rondor horn to heal himself. Then he has a brief battle with Wonder Woman, who puts him under control with her magic lasso and compels him to tell her what has occurred.
Finally, Mon-El, still in the Zone, tells Superman and Charlie Kweskill that, unknown to Jor-El, there are other levels in the Phantom Zone, though only one has been penetrated so far by some Zoners. Superman and Charlie head into the next level, seeking an escape in time to save Earth.
