Superman #24/1974

In a rare moment of father-son tension, Superman and Superman Jr. join Batman and Batman Jr. at a retreat designed to bridge the gap between generations—only to find that even the best intentions can plunge them into deeper misunderstandings. With Dr. Zamm and Mr. Bell overseeing the experiment, the line between mentor and protégé blurs in a story where trust is tested as much as strength.

In this gripping sequel, Dr. Zamm’s shocking realization that Superman and Batman have swapped sons sets off a chain of events that throws both families into chaos. As the two heroes grapple with the mix-up, a far more urgent threat emerges: a prototype Super-Agent has escaped from a government isolation cell, and the city is now in danger.

In "Tausche Vater, tausche Sohn! - Teil 3 : Der Atem des Todes," Superman and Superman Jr. face a chilling threat when the rogue Superagent, Mr. Bell [Bio-X7], unleashes a deadly nerve gas from a train, threatening to overwhelm the city. With Batman and Batman Jr. racing to contain the crisis, Dr. Zamm must uncover the truth behind the agent’s descent—before his robotic form consumes him completely.

When Clark Kent is unexpectedly granted a two-week vacation and Steve Lombard moves in to hide his wild partying from his visiting aunt, their unlikely roommate situation takes a surprising turn when a mysterious kidnapping unfolds at Mr. Giovanno’s Pizza. With Kaye Dane’s help and Superman’s secret identity in play, the duo must unravel the mystery before the truth about Steve’s antics comes to light.
