This Terminator was sent back in time to kill Sarah Connor before she could give birth to her son John, who will become the leader of the human resistance in the war against SkyNet and the machines.
This Terminator — which runs on a different fuel supply than the T-800 — is sent back in time in Terminator 3 by Kate Brewster, John Connor's future wife to protect John as a young adult.
Deceptively Human Robot: He can talk and behave more like a human than both versions of the T-800. If it wasn't for his Robotic Reveal when T-800 shot him, he would've continued fooling the audience into thinking he was human, let alone the hero.
Not So Stoic: Like all Terminators, normally stony-faced and uncaring, but is genuinely surprised/shocked when hit in the chest by a grenade by the T-101 (giving an Oh Crap look).
Power Incontinence: In the extended edition, after being frozen, shot, thawing, and reassembling, he begins glitching and his body parts take on the texture of whatever surface they touch.
Other forms played by: Mark Famligetti (2003), Claire Danes (2003)
This Terminator was sent back in time in Terminator 3 to kill John Connor and several of the human resistance's top fighters, as well as to help ensure the launch of SkyNet.
Big "NO!": Sarah almost makes it out of the asylum, but she see the T-800 walking out of an elevator. After saying "no" in a low tone of disbelief, it turns into this out of sheer terror.
My God, What Have I Done?: Silently after the attempted hit on Dyson. Exacerbated by the fact that not only had she taken on a dimmer view on human life than the Terminator she was traveling with, but had adopted the MO of the Terminator that first tried to kill her, right down to its weapon of choice (.45 Longslide with laser sighting).
Shell-Shocked Veteran: In the second film as a result of having lost her paramour to a cyborg that was hunting her down with the intent to kill her.
Take the Wheel: Is made to do this in both the first and second movie.
The Other Sarah: Played by Linda Hamilton's real-life twin sister, Leslie Hamilton Gearren, in Terminator 2. Leslie is seen as both the fake Sarah inside the steel mill and as the waitress Sarah in the nuclear nightmare scene. She is also seen inside the garage operating on the fake Arnold's head (Linda is seen with the real Terminator) in the Special Edition.
Drives Like Crazy: Without a doubt. Justified in that he learnt to drive After the End. He also instinctively drives cars at night without the headlights on, as doing so in the future would draw Aerial Hunter-Killers.
