Z000.M was a Series 800 Terminatrix activated in a Skynet facility in response to an incursion by the Resistance cell led by Colonel Mary Randall into a fully functional Skynet network complex six months after John Connor destroyed the Master Control central node. Upon maturation, this unit was immediately deployed via TDE to reinforce C890.L in countering the human offensive. Z000.M's Infiltration outersheath model appeared as a large, muscular Caucasian female with long brown hair.
