T-1000

The T-1000 is a fictional mimetic poly-alloy (liquid metal) assassin and the main antagonist in Terminator 2: Judgment Day controlled by the series main antagonist Skynet. 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 Awards and was ranked #39 in the Online Film Critics Society's "Top 100 Villains of All Time" in 2002, and #29 on Wizard magazine's "Top 100 Greatest Villains Ever" list.

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".
