After emerging from the time displacement sphere, at 1:52 AM on May 13, 1984 at the Griffith Observatory, the naked Terminator encountered three punks roaming the streets and forcibly demanded their clothing. At some unspecified time later, in the earlier hours of the morning, it went to a gun shop to acquire weapons for its mission, killing the shop's proprietor. The Terminator then checked a phone book for a list of Sarah Connors, finding a total of three. It proceeded to kill Sarah Ann Connor and Sarah Louise Connor before tracking down its intended target, Sarah Jeanette Connor, in Tech Noir. The Terminator nearly succeeded in killing her. However, Kyle Reese, a soldier sent by the future John Connor, helped Sarah to escape.
A chase ensued and the Terminator was injured in a car crash, damaging its arm and left eye. After removing the useless flesh eye and revealing its cybernetic eye, the Terminator wore sunglasses to hide its features. Armed with an assault rifle and shotgun, it then went to an LAPD police station to terminate Sarah, and while it went on a shooting spree, it failed to eliminate Connor. It later tracked down Sarah and Kyle at the Tiki Motel, but the two escaped. The Terminator then pursued them on a high speed motorcycle through a tunnel, and then drove a gas truck while Kyle used a pipe bomb to destroy it. However, while the truck was destroyed, the Terminator was not. Its living tissue was burned away by the fire and its endoskeleton was revealed. It chased Kyle and Sarah into a factory, where Kyle attempted to blow it up, but it still survived. Sarah Connor finally destroyed the robot when she crushed it in a hydraulic press, just seconds before it was about to choke her.
Terminator 2: Judgment Day
The same arm that came so close to killing Sarah Connor and its damaged CPU had survived the hydraulic press. Dr. Miles Bennett Dyson, a cybernetics scientist and a high-ranking employee of Cyberdyne, was tasked with creating a new neural-net processor from these two pieces of unknown-sourced advanced technology.
Miles studied the processors and was able to build a revolutionary new brand of automated systems, a more-advanced form of artificial intelligence and making other existing computer systems obsolete in comparison. The project eventually reached the point where he nearly completed a prototype of the processor. Like how Kyle Reese's entrance into the timeline altered the fathering of John Connor, the introduction of the Terminator's remains altered and accelerated the rise of Skynet, introducing another alternate future revolving around a predestination paradox. The remains were recovered by John Connor (Now ten years old) and his mother Sarah and destroyed by being thrown into a vat of burning steel in an attempt to change the future and eliminate Skynet once and for all.
In comparison to most other Terminators, who could exhibit emotional attachment, frustration, shock, fear and a sense of humour, the first T-800 was extremely emotionless, cold and ruthless; it almost never showed any facial expression beyond a cold and flat face, and it usually only spoke when it meant to engage others for information or when it intended to throw unwanted attention off of itself. The T-800 was noted to have an "attitude problem," tending to physically throw others out of its way to get past them or to use a phone booth. The T-800 was also very brutal and completely merciless, and was quick to killing when others in any way didn't cooperate with its plans and demands. Like most Terminators, the first T-800 was single-mindedly and inhumanly relentless in completing its mission at all costs, to the point that it continued its pursuit of Sarah Connor without giving up, even when it lost its skin sheath and its legs in the process.
Despite its almost-blank personality though, the Terminator did still possess just enough social information to calculate what the best verbal response with which to throw off unwanted attention was. It was also intelligent and resourceful enough to calculate multiple different methods of tracking down and/or killing Sarah Connor; from pursuing and murdering all Sarah Connors named in a phonebook, to impersonating Sarah's mother over the phone in order to obtain her location, to attempting to run Sarah down with a commandeered truck.
