R.E.C.R.

R.E.C.R., Short for Reverse-Engineered Collective Robot, is a robotic, war machine created at Area 50.

History
It's prime programming was to defeat "the enemy", but due to a programming flaw, it considered everything to be that enemy. It was awakened by Coop and fed off of Megas' electrical energy to become stronger. After trapping Megas in Area 50, R.E.C.R went in search of power for its need to consume vast amounts of energy to operate properly. After R.E.C.R attacked Las Vegas, Coop defeated it and later buried the robot in the Grand Canyon to prevent it from draining any more power.
