A fictional artificial being from the Terminator Science fiction series. It first appeared in the Terminator 2: Judgment Day film from 1991, where it was the main antagonist and was played by American actor Robert Patrick. It also appears in the Terminator: The Sarah Connor Chronicles TV series from 2008 where it was played by Scottish actress and female musician Shirley Manson (vocalist of the American rock band Garbage).
The T-1000 Terminator is a type of artificial creature (technically still a robot) programmed as an infiltration assasin unit.
They are made of liquid metal, what allows them to imitate the form of everything they touch, including organic materials and living beings.
The T-1000 are very intelligent, strong, resilient, very agile and fast. They also can create blades and melee weapons from their limbs. Some of their only weaknesses are extreme temperatures and explosive weaponry.
The T-1000 was originally conceived by James Cameron as the main antagonist for the first Terminator film, but since special effects at the time weren't advanced enough, he came with the T-800 design instead.
