Comments:
First official use of Gold Kryptonite, which permanently removes a Kryptonian’s super-powers. It had been used once before in the imaginary story starring Superboy in the first story of Adventure Comics #299.

Synopsis:
Phantom Zone criminal Quex-Ul is released from the Zone by Superman having completed his sentence. Quex-Ul swears revenge against Superman, whose father Jor-El sentenced him on Krypton. While Quex-Ul creates a magnet to gather Gold Kryptonite, Superman visits Krypton’s past to learn that Quex-Ul is innocent of his convicted crime.

When Superman returns, Quex-Ul tries to use the Gold Kryptonite against him. Supergirl informs Quex-Ul that he has been cleared of his previous crimes. This revelation causes the former Zone resident to save Superman, sacrificing his own powers to the Gold Kryptonite. The accident gives him amnesia, so Superman gets him a job at the Daily Planet.
