A Kryptonian Signal Jammer was a piece of Kryptonian technology that was used to block the signals of enemies.
History[edit | edit source]
When General Zod and his Sword of Rao invaded Earth 33 years after Krypton's destruction, they were defeated and sent back to the Phantom Zone by Kal-El, the last Son of Krypton. Some of the Sword of Rao's equipment was left behind however, including a Signal Jammer.
Criminals used one of the left behind signal jammer's to break into Wayne Enterprises R&D Facility in Metropolis. As they were confronted by Superman while they made their escape, a captured Bruce Wayne knocked out his guard and used the signal jammer on a different frequency to subdue everybody, including Superman.
