A Cyberdyne Systems Model 101 Terminator with living tissue over a metal endoskeleton, played by Schwarzenegger, is the main antagonist of The Terminator, the original Terminator film. Another Model 101, having been reprogrammed by the human resistance in the future, is the protagonist of Terminator 2: Judgment Day. In Terminator 3: Rise of the Machines, Schwarzenegger plays a Terminator known as T-101. His character is destroyed at the end of each of these films. The fourth installment, Terminator Salvation, reveals the origin of the character. Roland Kickinger was cast as the principal actor but CGI was used to superimpose Schwarzenegger's face from the original 1984 film. In the fifth installment, Terminator Genisys, Schwarzenegger plays an aging T-800 (reprogrammed by an unknown party) and becomes a mentor and father figure to a young Sarah Connor of an alternate timeline, and Brett Azar portrays the original Terminator from the first film, with Schwarzenegger's then-likeness utilized via CGI.

The character's catchphrase, used throughout the franchise, is "I'll be back", though at times with variations; in Terminator 3, it says about the T-X, "She'll be back", and later, "I'm back"; and in Terminator: Dark Fate, it tells its family, "I won't be back". Throughout the films, other characters use the phrase, such as John Connor in Salvation (as Schwarzenegger does not appear in the film) and Sarah Connor in Dark Fate. The Terminator (1984) The Model 101 is sent back in time to terminate a single target, Sarah Connor (Linda Hamilton), in 1984, to prevent the birth of her son, John, the future leader of the Human Resistance. Lack of surviving records in the future meant that he was limited to only knowing Sarah's name and that she lived in Los Angeles at the time, with the result that he killed two other Sarah Connors in the same city before he found his target.
