Lego Terminator T-800

The Terminator CPU is a room-temperature superconducting artificial neural network with the ability to learn. In Terminator 2, The Terminator states that "the more contact he has with humans, the more he learns." In the Special Edition, he says that Skynet "presets the switch to 'read-only' when Terminators are sent out alone", to prevent them from "thinking too much". Sarah and John activate his learning ability, after which he becomes more curious and begins trying to understand and imitate human behavior. This leads to his use of the catch phrase "Hasta la vista, baby." A line spoken by the Terminator at the end of the movie shows that Terminators have the potential to understand emotion: "I know now why you cry, but it is something I can never do." Sarah muses in the closing narration that the Terminator had "learned the value of human life". This emotion was so strong he was even able to defy John Connor's orders, thus defying his programming, for the greater good.
Organic covering
The flesh-covering that is used on the majority of Terminator models has similar qualities to real human muscle and skin, as well as the ability to sweat, simulate breathing, and produce realistic body odor. Although Terminator flesh does contain blood, it only displays very minimal bleeding when damaged and has never been shown to experience any kind of profuse bleeding even from massive lacerations, dozens of gunshot wounds, or even complete removal. In the absence of a circulatory system, the flesh uses a system of "nanobots" which maintain the skin. It is unknown what biological processes take place to sustain the flesh covering, since Terminators do not require the consumption of food. Under 2007-era analysis, this blood is shown to be similar to human blood, using a synthetic oxygen carrier rather than human red blood cells, as Terminator endoskeletons contain no bone marrow. Terminator flesh heals by itself, and at a much faster rate than normal human tissue and has never been shown to bruise or discolor from trauma, even after several days. However, a Terminator's flesh covering can die if it sustains adequately massive damage, at which point it takes on a waxy, corpse-like pallor and begins to decompose.
