After Kyle sacrifices himself to damage the Terminator with a pipe bomb that destroys its legs, Sarah crushes the remaining endoskeleton in a hydraulic press to shut it down permanently. A Model 101 is captured by the resistance, reprogrammed by the future John Connor (Michael Edwards), and sent back to the 1990s to protect young John (Edward Furlong) from a T-1000 (Robert Patrick) dispatched to kill him. While interacting with the Connors as they work to prevent Judgment Day (a scene from the extended version of the film shows the Connors explicitly reprogramming the Terminator to be capable of learning rather than Skynet's default "read-only" programming), this Model 101 is taught how to speak in slang-like terms, such as "Hasta la vista, baby", and encouraged to act more human, to the point that it develops into an almost fatherly role for John. Sarah reflects that the Model 101 is the first male figure John has ever had in his life who can be guaranteed to always be there for him. The T-1000 chases Sarah, John, and the Model 101 into a steel mill and overpowers the latter in hand-to-hand combat, impaling him through the chest and destroying his main power supply. However, the Model 101 activates a backup power source, frees himself, and blasts the T-1000 into a vat of molten steel with a grenade launcher to destroy it. Leading up to these events in the second film, Cyberdyne recovers one forearm and the damaged CPU chip from the Terminator in 1984 and uses those components to radically advance its research and technology, leading eventually to the creation of the machine intelligence entity Skynet. In "Terminator 2", John steals the items from Cyberdyne's research lab and later throws them into the vat to destroy them. Because he cannot self-terminate, the Model 101 has Sarah lower him into the steel in order to destroy his CPU as well and thus prevent his technology from being used to create Skynet. In the third film, a T-101 Terminator portrayed by Schwarzenegger is reprogrammed to protect John Connor (Nick Stahl), as well as his future wife Kate Brewster (Claire Danes), from a T-X (Kristanna Loken). The T-X is also designed to kill other Terminators. The T-101 is powered by two hydrogen fuel cells, one of which it discards after being damaged by the T-X. The T-101 tells John that his efforts in the second film did not stop Judgment Day, but merely delayed it.
