[quote]HERCULANs (Humaniform-Emulation Roboticized Combat Unit with Leg-Articulated Navigation) (or 'HERCs' for short). On November 29, 2471, the race for true artificial intelligence ended when Sentinel Cybertronix activated Project: Prometheus. Prometheus was a prototype, the first cybernetic-hybrid machine, or Cybrid. It was incredibly intelligent, and its success quickly paved the way for mass-production of Cybrids. These new machines, free of human needs and exceedingly intelligent and efficient, proved invaluable in countless fields, including mining and space exploration. Military minds saw another usage for Cybrids: incredibly fast-thinking pilots for the recently developed HERCULAN war machines, pilots that could not die. Militaries quickly took control of Cybrid production, and factories around the globe began churning out Hercs adapted for Cybrid use, at enormous expense. Those who didn't have the resources to build Cybrids began to wage small wars on those who did. While the humans fought themselves for control of the Cybrids, the AI machines watched and calculated. Apparently they concluded that humans were not fit to control Cybrid destiny, for the Cybrid armies all rose up against humanity in a strike known as the Overthrow. Unprepared for this blow in the ashes of nuclear war, humanity was helpless as the Cybrids seized control of every military base, space port, and city.
