The G.K.D. (Global Killer Device) once belonged to the Fallen. They left the device on earth years before, originally to destroy the Guardians and other enemies. Before the Battle of Outpost IV in 2032, the Fallen were planning to activate the device, so that the EDF were focused on Earth while the Fallen would destroy Outpost IV. However, Doctor Alexia managed to stop them as they were activating the device, deep out in a desert in Africa. The G.K.D. would have been taken away by the US government, not long after then. Years later, after the death of Johnson and Susie, the sinister Claw reforms Dark Origin and steals the device from the Global republic. He later uses the weapon against his enemies, this causes the near extinction of the human race in 2040.
