The FK Reaper, or Reaper class assault machine, was a bipedal HK unit utilized by Skynet in the alternate future of Terminator 3: The Redemption. An FK Reaper possessed four optical sensors and an arsenal comprising a heavy plasma gun and a flamethrower. The FK Reaper is apparently compatible with T-850 CPUs, allowing John Connor to install the chip of his protector into one such unit.
