Superman, you're a fool to have freed me! I'm going to destroy you forever with an amazing secret weapon -- Gold Kryptonite! 
- — Quex-Ul
Superman #157 is an issue of the series Superman (Volume 1) with a cover date of November, 1962.
Synopsis for "The Super-Revenge of the Phantom Zone Prisoner!"
Phantom Zone prisoner Quex-Ul's 25-year sentence is up, and Superman releases him from the Zone, to which he was sent for allegedly killing the rondors and stealing their "healing horns" for use in a medical scam. Quex-Ul promises to destroy Superman with Gold Kryptonite, a new variety that Superman knows nothing about. They battle inconclusively when Quex-Ul calls a truce so that he can save a man whose life is endangered, which causes Superman to question Quex's criminal inclinations.
Superman travels back in time and space to pre-cataclysm Krypton. There he witnesses the real slayer of the rondors, Rog-Ar, using a hypno-jewel on Quex-Ul, who had intended to turn him in. Instead, Rog-Ar hypnotically compells Quex-Ul to operate his "hall of healing", to take the blame if exposed, and forget Rog-Ar.
Quex-Ul has trapped a submarine in an undersea crevice near the box of Gold Kryptonite, hoping to lure Superman into a trap. Quex-Ul boasts to Supergirl that he has trapped Superman, but she reveals the truth of his false imprisonment. Repentant, Quex-Ul frees the sub, exposing himself to the Gold Kryptonite which extinguishes his powers, and almost his life. When his body drifts far enough away from the Gold Kryptonite, Supergirl and Superman rescue him. Once conscious, Quex-Ul has amnesia from the Gold K exposure. Superman arranges with Perry White to have Quex-Ul, who thinks he is an Earthman, employed in the Daily Planet's production department.

Synopsis for "Superman's Day of Doom!"
Metropolis is set to observe Superman Day with a great parade in which Superman and many of his friends, including Supergirl and some Legionnaires, will participate.
Superman is given a prediction machine from the Cybern Galaxy in return for a good deed he once did them. The machine, which turns up at the Daily Planet, has the power to predict the answers to three questions about the future. Since Clark Kent has been threatened by a gangster lately, he asks who will rescue him if he is endangered that day, and the answer comes back: "L.L."
Later, Superman's life is endangered when Bizarro leaves him a "gift" of Green Kryptonite. Superman hopes for aid from any of his "L.L." friends, including Lana Lang, Lois Lane, Lori Lemaris, Lightning Lad or Linda (Supergirl) Lee, but none of them are aware of his plight. Finally, Superman is saved in the nick of time by Steven Snapinn, a Little League baseball player. Superman presents Steven and his team for special recognition at the Superman Day rally.

Notes
- "The Super-Revenge of the Phantom Zone Prisoner" was reprinted in Superman #227 and Superman: Tales from the Phantom Zone.
- Since Quex-Ul's sentence was 25 Earth years, and he was convicted in Krypton before its destruction, and Kal-El was launched to Earth during Krypton's final moments, Superman is presumed to be around 25 in this issue.
- Only Va-Kox, Jax-Ur and Quex-Ul are named Phantom Zoners in this issue.
- Superman and Supergirl do not discuss the option of sending Quex-Ul to the bottle city of Kandor, where he could live among fellow Kryptonians and, if his memory returned, it would not endanger Superman or Supergirl's secret identities. Because Quex-Ul remains on Earth, living in Metropolis, years later some Phantom Zone criminals are able to escape by mentally manipulating Quex-Ul.[1] This escape results in numerous deaths, both human and Kryptonian, including Quex-Ul's
- "The Super-Genie of Metropolis" was reprinted in The Best of DC #8.
