Superman #7/1976

In "Das Wunder des durstigen Donnerstags," a young historian from the year 3475 travels back to 1975 to uncover the mystery behind a day when Metropolis fell into terror over water. When a lab accident unleashes a dangerous substance into the city’s water supply, panic spreads and a young scientist, Dr. Larry Ishmael, takes a wrong remedy and spirals into chaos. With the help of Lois Lane, Steve Lombard, and Inspektor Bill Henderson, Superman must contain the crisis—putting the entire city to sleep and holding the unstable man at bay until dawn.

When a thief infiltrates the Legion's headquarters and dares them to stop him from stealing the Mirakelmaschine within 24 hours, the young heroes face their greatest test yet. As the machine’s power to turn thoughts into reality proves too dangerous to destroy, Ultraboy is pushed to the edge when the Legion’s ship approaches the thief’s hidden lair inside a space dragon’s maw—triggering a long-buried trauma. Can he overcome his fear in time to save them all?
