The Anti-Metallix device was a weapon created by Doctor Kintobor and The Underground when the Brotherhood of Metallix turned Mobius into Planet Metallix. Although it was designed to affect a Metallix, the device had never been tested before Kintobor gifted it to Sonic the Hedgehog. After travelling back through time in the Omni-Viewer, Sonic attached the device to the back of a Metallix's head. The technology altered the target's visual circuits, making it believe that the other Metallixes were its targets. Before the Metallix could run out of new targets, the heroes fled the scene.
