T-1000

The T-1000 is a fictional android assassin featured as 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);[1] Schwarzenegger’s character explains how 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.
