The T-1000 is a Cyberdyne Systems Infiltration Terminator. Previous infiltrators required a metal endoskeleton bonded to an organic matrix to create a Human-like appearance, but the T-1000 uses a mimetic poly-alloy that allows it to take the molecular structure of anything with which it comes in contact. It is an autonomous unit sent back in time to kill John and Sarah Connor. To accomplish its mission, it can form stabbing weapons using its body, imitate a person's voice, and run as fast as a speeding car. The T-1000 can survive extreme temperatures. Extreme cold slows the unit, and it does have a melting point equal to or lower than that of steel. When its mimetic poly-alloy is separated from its host, it can independently return to a larger mass. While the T-1000 has a repertoire of Human bodies and clothes to mimic, it prefers its default face and the uniform of police officers as they lend an air of authority.
Major Plots
I'mma Cop, You Idiot.
In 1995, a T-1000 Terminator is dispatched by Skynet in the future to kill John and Sarah Connor. Luckily, when the T-1000 first arrives, it runs into a police officer and patrol car. The T-1000 kills the cop and uses his car to find the likely locations of John Connor. It travels to the home of John Connor's foster parents. It does not find him there, but it does get a current picture of John Connor. It shows it around the neighborhood and discovers that John Connor is at the local shopping mall. The T-1000 goes to the mall and asks if anyone has seen John Connor. He soon finds the Connor boy in a video game arcade. He pursues his quarry.
In a utility corridor, the T-1000 draws his stolen police sidearm and tries to kill John Connor. Unfortunately for him, a T-800 Terminator reprogrammed by the Human resistance in the Future intervenes. The T-1000 fails to kill John Connor, but it does manage to kill a maintenance worker drinking coffee. The T-1000 continues to fire, but the T-800 shields John Connor with its body. The T-800 fires five shotgun blasts into the T-1000, but the T-1000 reforms around the damaged areas. The two Terminators engage in a brawl, tossing themselves around the shops of the mall. The T-1000 wins this fight and runs after John Connor.
The T-1000 Merely Shrugs off Flames.
John Connor flees on a mini-bike, so the T-1000 commandeers a Semi Truck and chases the boy with the intent to crush him. The pursuit enters the Los Angeles River aqueduct system, and the recently recovered T-800 joins in the chase. Eventually, the T-800 does enough damage to the T-1000 and its vehicle to cause it to flip. The T-1000's truck explodes, but the T-800 knows the flames will only delay the T-1000. The T-800 and John Connor escape the scene. The T-1000 dramatically walks out of the flames in its mimetic poly-alloy form. It struts as if it knows someone is watching.
The T-1000 changes tactics and returns to John Connor's foster home. It kills his foster parents and awaits for John Connor to call home. He does. The T-1000 mimics John Connor's foster mother Janelle. Dog do not like Terminators and the family dog Max starts barking at the T-1000. The T-800 suspecting a trap tests the person on the other end of the line by impersonating John Connor's voice. He gives the wrong name of the dog, "Wolfy," instead of Max. The T-1000 falls for the trick, and his prey are warned of its ambush. It goes to the next likely place the John Connor would go.
Ha-ha! I Was the Floor the Entire Time.
The T-1000 arrives at the Pescadero State Mental Hospital to set an ambush for John Connor using his mother Sarah Connor. It mimics the floor and kills a guard. It disguises itself as a guard and finds Sarah Connor's cell, but Sarah Connor is recently escaped. The T-1000 reverts to its police officer form and chases after her. John Connor and the T-800 rescue Sarah Connor, but the T-1000 continues to follow. The T-800 shoots it in the head which suns it briefly. The T-1000 then uses a variety of stabbing weapons to stab at the fleeing group. Sarah Connor hijacks a sheriff's department patrol car, and the group drive away from the T-1000. The T-1000 latches onto the car and continues its assault. The T-800 shoots the T-1000 off the back of the car. The T-1000 stops to think about its next move.
"Get Out."
Days later, a call comes over the police radio that indicates that John Connor is attacking Cyberdyne Systems Research Headquarters. The T-1000 heads to the location but is too late to stop them. He commandeers a helicopter and chases the still fleeing Connor Party down the highways of Los Angeles. The Connors drive a stolen SWAT van but are forced to switch to a stolen poultry pickup truck. The T-1000 switches from its helicopter to a truck hauling liquid nitrogen. The chase ends at a steel foundry in the Industrial Park area of Los Angeles County.
I'm Melting! Melting! Oh, What a World!
The T-1000 experiences some major setbacks in its assassination attempt on John Connor. First, the liquid nitrogen truck ruptures, freezing it. Its mimetic poly-alloy cannot function in low temperatures. Luckily, the T-800 shoots the frozen T-1000, thus increasing its relative surface area and thaw rate. The T-1000 melts and reforms into bipedal form. Its prey flees into the foundry. The T-1000 struggles with the T-800 and uses the steel beams and mechanical gears of the foundry to inflict damage. The T-1000 finds Sarah Connor and mimics her in an attempt to lure John Connor into a trap. In a cooperative effort, Sarah Connor and the T-800 shoot the T-1000 into a smelting cauldron using a combination of shotgun blasts and a 40mm grenade. The T-1000 transforms into all the patterns it has learned before finally dying. It loses coherence as it dilutes in the steel.
Personality and Traits
We Are Not Amused.
The T-1000 is a merciless killing machine whose sole task is the destruction of its target. Any emotions it exhibits are merely tricks to either prevent the suspicions of Humans or to trick its target. The T-1000 is an advanced system but shows no interests outside of its task. Its thoughts and actions are highly ordered and organized. Despite its constant failure, it formulates new plans without frustration. It does have a preference for police uniforms, but this is a logical decision based on the position of power police have in society.
