The Cyberdyne Systems Model 101 Series 800 Version 2.4 Infiltration-Combat Unit, once referred to as "Uncle Bob", was sent from the future to arrive in Acton, California on June 8, 1995. Its mission was to protect young John Connor, which it successfully completed.
Hasta la vista, baby!
Terminator 2: Judgment DayEdit
To protect his younger self in the past, John Connor reprogrammed this Terminator and sent it back in time via the time displacement sphere. Upon arrival, it encountered a group of bikers, stealing one's clothing and the bar owner's sunglasses and shotgun.
The T-800 then tracked down John Connor in a shopping mall. When it met the T-1000 sent by Skynet to kill Connor, a lengthy chase ensued, but the two managed to escape the T-1000. Connor questioned the Terminator about itself and who sent it. The Terminator answered that it is a cybernetic organism, having living tissue over its metal endoskeleton. It told John that it was his future self who sent it to protect him.
John and the Terminator go to the Pescadero State Hospital to help free John's mother, Sarah, who was also trying to escape from there as well. The Terminator later told John and his mother that it has the ability to learn. In the Extended-Release version of the film, however, the three go to a garage and Sarah tried to kill the Terminator by smashing it CPU, but she was stopped by John, who felt that it was needed. Later on, John started teaching some things to it in an effort to help it "blend in" with humans better (some of the things he taught the Terminator included the cult phrase "Hasta la vista, baby!"). When Sarah asked it how Skynet was created, it answered that Miles Dyson was the most directly responsible person. It also explained that Skynet became self-aware after its creation, and began to deny human authority.
The group later encountered Dyson, but didn't kill him. The Terminator explained him the consequences of his research. The three, along with Dyson, attempted to destroy the Cyberdyne building to prevent Skynet from being created. They were soon approached by the police. John, Sarah, and the Terminator escaped the building while Dyson blew up the building with himself inside.
The three were encountered again by the T-1000. The Terminator succeeded in destroying it when it fell into molten steel. Afterward, John drops the CPU and the arm of the first Terminator into the hot liquid. Since the Terminator had a computer chip in it, it also planned to destroy itself to prevent its technology from being discovered by others to create Skynet. John begged it not to be destroyed, but it had to fulfill its mission. When John cried, the Terminator understood why, but could not cry itself because it was a machine. It hugged John for the first and very last time, and having finally earned Sarah's respect, shook her hand offered to a brother warrior. As it is lowered into the steel below, the Warrior of Steel-in-Flesh gave John an encouraging thumbs up before sacrificing its life for humanity's future. The machine also renewed Sarah's hope in humanity as she mused that if a machine could learn to value human life, then so could humans.
This Terminator had all the strengths and capacity of the first unit, and was very logical, and at first seemed to have a limited capacity for human emotion and learning.
After his learning capabilities were activated, the Terminator began to exhibit other human traits such as humor, quipping "I need a vacation" after defeating the T-1000, and an understanding for compassion, as he tenderly wipes John's tears away and hugs him like a father before allowing itself to be destroyed to save humanity. John laters says to a T-850 that the T-800 was the closest thing he had to a father. Next to the Guardian introduced during Terminator Genisys, this model has displayed the most "humanity", for lack of a better word, being able to use humor, taunts and expressions that are needless for a machine, no matter the circumstances, he smirked when discovering the mini-gun and later again when asking John to trust him, pulled a shrugging expression when John yelled at him for not yet realizing why he can't kill people, more evidence is in his speaking tone, while logical and computer like at first, he began speaking more like a human at the end of the film: "John, you got to go now, go! now!" - T-800 speaking with stress and urgency.
He was able to understand why humans cry and eventually able to sacrifice itself for humanity when its only mission was simply to protect John Connor, during this action he was able to defy John's order which would be hardwired in his programming.
