Fictional character biography
Pre-Crisis
First appearing in Superman #157 (Nov. 1962), Quex-Ul was a Kryptonian exiled to the Phantom Zone when he was convicted of killing rondors, an endangered species, to use their healing horns for the purpose of profit. He confessed and spent his time in the Zone, but was released by Superman when his time was up. Not a grateful sort, he attempted to lure Superman into a gold kryptonite trap, until Superman discovered that Quex-Ul had actually acted under the mental control of another Kryptonian, Rog-Ar, the true rondor killer. Learning this, Quex-Ul threw himself into the trap to save the hero, losing his powers and memory.
In the 1982 The Phantom Zone mini-series, he later works at the Daily Planet, believing himself to be an Earthman named "Charlie Kweskill". Susceptible to unconscious influence by Phantom Zoners, he unwittingly frees them and is himself trapped in the Zone along with Superman. Together they seek a way out of the Zone, ultimately facing a malevolent entity called Aethyr, whose mind creates the Phantom Zone. On arrival, Superman and Quex-Ul find themselves wearing each other's clothes, and "Charlie" wonders if he now has super powers. It is unclear whether his powers or memory have actually been restored, the costume swap having been effected as some sort of amusement by Aethyr. To save the Man of Steel, Quex-Ul flies towards Aethyr and dies in a shower of fiery breath, sacrificing his life in a final act of redemption.
