Giant Superman Album #40

In "Amazo’s Big Breakthrough," Superman faces his most dangerous foe yet when Amazo, a synthetic warrior with the power to mimic any hero, gains the upper hand as a wave of red sun radiation drains Superman’s strength. With the Justice League trapped in another dimension, Amazo turns his sights on his creator, Professor Ivo, seeking to be shut down—but Superman, weakened but determined, must protect Ivo before Amazo’s rampage reaches its climax.

In "The Super-Revenge of the Phantom Zone Prisoner," Superman grants freedom to Quex-Ul after his sentence in the Phantom Zone, only to face a vengeful vow from the former prisoner—targeting the son of the man who once condemned him. As Quex-Ul’s actions blur the line between villain and hero, Superman journeys back to Krypton to uncover the truth, discovering a past shaped by manipulation and deception. When the truth comes to light, Quex-Ul makes a final, selfless choice that changes everything.
