One of the many weapons used by the robots in their struggle against the humans. Destroyer Discs attach to enemy battle machines and send out waves of electricity, frying the battle machine's circuits. It is much stronger than the humans' Energy Disc Launcher and does permanent damage instead of temporary shutdowns. It takes, however, some time to fry the circuits and so, if it is somehow removed quickly, there is little danger. The humans have a weapon similar to this in everything but effect. It is called an Energy Disc Launcher.
