Superman Batman #50

Long before Superman and Batman became the legendary World's Finest team, an extraordinary encounter between their fathers helped shape the future of both heroes.

Years ago, Thomas Wayne and Martha Wayne are traveling through Kansas when they witness a mysterious object falling from the sky. Thomas investigates and discovers a strange Kryptonian device connected to the arrival of Superman's father, Jor-El.

In the present day, Superman and Batman uncover an ancient Kryptonian artifact that activates a dangerous chain of events. As mysterious technology begins taking control of machinery in Gotham and threatening the surrounding areas, the heroes must investigate the connection between the artifact and their fathers' shared history.

With the Titans joining the fight, Superman and Batman face a threat that could change everything they know about their families and their destinies.
