The Bat-Radia was a device designed by the Batman of Zurr En Arrh, a scientist named Tlano, who considered it to be the most valuable object in his utility belt. The purpose of the Bat-Radia was to issue electronic molecules that caused controlled disturbances in the atmosphere of Zurr En Arrh, thus 'jamming' atmospheric molecules — and could even render useless the motors of jet-cars used by Tlano's fleeing enemies.
The Bat-Radia would prove to be instrumental in the defeat of robot invaders which Batman had been brought to Zurr En Arrh to help defeat, as he had Superman-like powers on that world. The Bat-Radia's electronic molecular shower disrupted the electric force of the robot invaders that had made them invisible, causing them to become visible again — leading to their easy defeat by Batman.
Presumably Tlano had another Bat-Radia, as the one used in Batman - The Superman of Planet X! was given to Batman as a keepsake of one of his strangest adventures.
The Bat-Radia was found by Bruce Wayne on a derelict's car. It was an old transistor radio, but due to Bruce's loss of memory, the backup personality of the Batman of Zur-En-Arrh kicked in and created the Bat-Radia. Everything seemed to point to the fact that Bruce had in fact gone mad, but the Batman of Zur-En-Arrh tampered the old transistor radio to send signals instead of receiving and once it was activated, it send a signal to the Batcomputer that caused all the exits of Arkham Asylum to be locked shut, thus allowing Batman to eliminate the Black Glove and destroy their organization.
- The Bat-Radia was originally conceived in Earth-One continuity as per Batman #113, but it has since been re-introduced in the "Batman R.I.P." storyline in 2008.
- The Bat-Radia given to Batman by Tlano worked only within the atmosphere of Zurr En Arrh, thus Batman would not be able to make use of the device when he returned to Earth.
