Superman Taschenbuch #13

When a dangerous experiment turns leaden Kryptonite into a weapon, Superman is struck and suddenly recalls the day all Kryptonite on Earth inexplicably turned to lead—leaving him haunted by a memory that may hold the key to the present crisis. With Lois, Jimmy, and Perry racing to uncover the truth, and Professor Bolden’s research pointing toward a hidden pattern, Superman must piece together a past that now threatens the present.

When Jimmy Olsen’s call to his father abruptly cuts off, he’s drawn into a mystery that defies belief: the entire city of Hartsdale has vanished, snatched away to become a display in a cosmic museum. With help from his father, Professor Mark Olsen, and the relentless reporting of the Zeitungsboys, Jimmy must uncover how a whole city was stolen—before the truth becomes another exhibit behind glass.

In the second part of "Das Kosmo-Museum," Superman races to find Jimmy Olsen while Kandor and Lois Lane are mysteriously transported to the museum's planet. When Superman finally locates the bottled city, he's struck by the red sun's power—leaving him powerless just as new dangers emerge.

In "Das Kosmo-Museum - Teil 4: Der Lichtkäfig," Superman races to free Krypto from a dazzling, prison-like cage of light, sending the loyal dog on a critical mission to destroy a hidden generator keeping them trapped. Along the way, Krypto crosses paths with Lois Lane and Jimmy Olsen, setting off a chain of tense, high-stakes moments in the heart of the mysterious museum.

In "Das Kosmo-Museum - Teil 5: Endkampf um Kandor," Superman, Nachtschwinge, and Flammvogel face a desperate stand as Phantomzone escapees threaten to ransack the city of Kandor. With General Zod and Ver-Na closing in, the unlikely allies must confront their pasts and unite—or fall apart—before the museum’s final defenses collapse.

In the final chapter of the Kosmo-Museum saga, Supergirl traces the missing city of Kandor to the mysterious museum planet, where she reunites with Superman, Lois Lane, and their allies—including Zor-El, Allura, and Krypto—in a desperate race to restore the stolen cities. With the fate of Kandor and countless others hanging in the balance, the heroes must confront the alien forces behind the museum’s deception before the final pieces of their world are lost forever.
