Superman #54

In a haunting chapter of the "Time & Time Again" arc, Superman arrives in the Warsaw Ghetto in June 1943, where the past has fractured and a hidden Nazi plot threatens to unravel history. With the help of a few desperate souls—including a young woman named Sonia and a defiant resistance figure named Schlomo—Superman races against time to stop a stolen atomic bomb carried on a Nazi train. As the city braces for destruction, he faces an impossible choice: save the present or risk everything to preserve the future.

In the heart of the Cadmus D.N.A. Project, a towering green clone of Jimmy Olsen—now a rampaging D.N.Alien—attacks the Guardian, trapping him with his elongated limbs. The Newsboy Legion springs into action, only to be turned on by the creature, forcing Dubbilex to intervene. As alarms echo through the facility, Shino Kurosawa and Mr. Barstow race outside, while the Guardian, determined to stop the threat, leads the clone into the project’s dangerous nuclear corridors—leaving Dubbilex to protect the boys.
