Character nomenclature
The end credits of all three Terminator films list Schwarzenegger's character as simply "The Terminator". Later films call the newer terminator characters by their model numbers (T-1000, T-X, etc.). The only consistent name for Schwarzenegger's Terminator character has been "The Terminator". Kyle Reese in The Terminator and Schwarzenegger's character in Terminator 2 refer to it as a "Cyberdyne Systems Model 101", and in Terminator 3, the Terminator refers to itself as a "T-101".

However, other sources contradict this designation. On the T2 Extreme Edition DVD, he is referred to as an 800 series and a T-800.[3] The T3 extras refer to him as an "850 series Model 101", a "T-850", and a "T-101".
