The T-1000 is a fictional nanomorph mimetic poly-alloy (liquid metal) assassin and the main antagonist in Terminator 2: Judgment Day. The T-1000 is portrayed primarily by Robert Patrick; however, being a shape-shifter, the T-1000 is played by other actors in some scenes of the film. In Terminator 2, the T-1000 is presented as a technological leap over the "800 Series" Terminator (Arnold Schwarzenegger). Described by Allmovie as "one of the most memorable roles in one of the most memorable films of the decade", Patrick's portrayal of the T-1000 earned him nominations for Best Villain and Best Supporting Actor at the 1992 MTV and Saturn Award and was ranked #39 in the Online Film Critics Society's "Top 100 Villains of All Time" in 2002.
A similar Terminator appears in the 2007-08 FOX television series, Terminator: The Sarah Connor Chronicles, where it is referred to as a "T-1001".
In the Terminator 2 storyline, the T-1000 is made of "liquid metal". Schwarzenegger's character explains that the T-1000 is a more advanced Terminator, composed entirely of a mimetic metal alloy, rendering it capable of rapid shapeshifting, near-perfect mimicry and rapid recovery from damage. Furthermore, it can use its ability to quickly liquify and assume forms in innovative and surprising ways, including fitting through narrow openings, morphing its arms into solid metal tools or bladed weapons, walking through prison bars, and flattening itself on the ground to hide or ambush targets. The T-1000 also had the ability to extrude small, simple items from itself. For example, it created a motorcycle helmet and a pair of sunglasses when these items were necessary for its disguise. The T-1000 can also change its color and texture to simulate flesh, clothing, and other nonmetallic materials. It is capable of accurately mimicking voices as well, including the ability to extrapolate a relatively small voice sample to generate any words or inflections it requires.
The T-1000 is effectively impervious to mechanical damage, such as being dismembered, shot with bullets, or attacked with explosive devices. Wounds close almost immediately, and any detached parts simply flow back into the T-1000's body. In T:2, this Terminator was even frozen using liquid nitrogen and shattered, but the pieces simply flowed back together after thawing. Temperature-based attacks are effective, however. Low temperatures can cause the liquid metal to freeze, which inhibits its ability to move or shapeshift. High temperatures degrade its ability to maintain a disguise; after emerging from a burning truck, the T-1000 appeared in its default liquid-metal state and was only able to reestablish its policeman disguise after cooling for several seconds. Only extremely high temperatures, such as molten steel used in the climax of T:2, are capable of disassociating its molecular structure and permanently destroying it.
