only one well-placed shot. In the second film, the Terminator says he can fully operate for 120 years on his power cell before it drains. In the finale to Terminator 2, his power source is damaged, and he is able to find an alternate source, described on the DVD commentary as heat sinks, harnessing the thermal energy from the hot surroundings. During both films, Terminators demonstrate the ability to continue functioning even after losing one or more limbs (both legs and one hand blown off by Kyle Reese, one arm crushed and torn off by rotating gears). In the third film, the Terminator—an 850 series rather than the 800 series depicted in the first two films—operates on two hydrogen fuel cells and discards one of them early due to damage. It explodes shortly thereafter with enough force to produce a small mushroom cloud. The endoskeleton is actuated by a powerful network of hydraulic servomechanisms, making Terminators superhumanly strong. For instance, in the third movie, Schwarzenegger's character was able to handle firing a Browning .30 machine gun from the hip with one hand, while holding a coffin containing an alive John Connor and a heavy cache of weapons, showing no signs of the extra weight being any real concern. Late in the first film, the Terminator is stripped of its organic elements when the tanker truck it is driving is blown up. What remains is the machine itself, in James Cameron's own words "a chrome skeleton, like death rendered in steel." In the later Terminator films, armies of endoskeleton-only Terminators are seen. They are visually identical to the one in the first film, and feature prominently in the "future war" sequences of those films. CPU The Terminator CPU is an artificial neural network with the ability to learn and adapt. It was also briefly referred to as a room-temperature superconductor. In Terminator 2, The Terminator states that "the more contact [it] has with humans, the more [it] learns." In the original film, it learns how to swear from the punks it encounters in the beginning of the film, and when a janitor of the building where one of the Sarah Connors he killed lived visits to ask about the odor from the room, it replies with "Fuck you, asshole", from a list of responses. In the second movie's Special Edition, it says that Skynet "presets the switch to 'read-only' when [Terminators]
