In Terminator 2, the T-1000's default form is portrayed by Robert Patrick, and in Terminator Genisys, by Lee Byung-hun, while other actors portray the T-1000 in the disguise of specific characters. It is further explained in the prologue of the film's novelization that the T-1000 was created through nanotechnology, and is a " Nanomorph", able to scan the molecular structure of whatever it is touching and visually mimic it. Aside from being able to camouflage itself by assuming the appearance of a nondescript object or take on the likeness of other humans that it terminates in pursuit of its goals, the T-1000's shapeshifting abilities enable it to form its hands into stabbing blades, slip through physical openings by oozing its liquid form, and instantly reform itself from any physical damage. The T-1000 is described in Terminator 2 as being composed of liquid metal, or a mimetic polyalloy ( nanorobotics) that it can manipulate to assume various forms. In the films, the T-1000 was created by the franchise's main antagonist, Skynet, a machine artificial intelligence that directs its robotic creations against the Human Resistance in an all-out war. A similar Terminator, referred to as a T-1001, appears in the Fox television series, Terminator: The Sarah Connor Chronicles.
A shapeshifting android assassin, the T-1000 is the main antagonist of Terminator 2: Judgment Day, as well as a minor antagonist in Terminator Genisys and the theme park attraction T2 3-D: Battle Across Time.
The T-1000 is a fictional character in the Terminator franchise.
