The Gamma Gun was a device created by Wayne Enterprises that emitted a steady stream of gamma radiation. Bruce Banner believed it could cure him of the Hulk. The original was stolen by The Joker and used on the Shaper of Worlds, but malfunctioned. Bruce Wayne, Wayne Enterprises CEO, hired Banner to recreate it, but interference from the Joker inadvertently caused it to never be finished.
