A Terminator, or T-Unit, is a type of Hunter-Killer designed to terminate other life forms. Various Terminators are built by an artificially intelligent computer called Skynet in order to wipe out the remains of the human race after Judgment Day.
Development of the Terminators in Alternate Timelines
How the original Terminators were built is unknown in the Alpha timeline. In the Original timeline, Cyberdyne Systems was able to reverse-engineer and develop robots from the scavenged hand and CPU of the destroyed T-800 in 1984. Cyberdyne Systems had created the T-70 Terminator to impress investors and people with military interests to finance them to improve robotics technology.
Later in Rise of the Machines timeline created by the destruction of Cyberdyne, the US Military and Cyber Research Systems used the reverse engineered technology acquired from Cyberdyne Systems to develop the T-1, the first model of the Terminator Series, as well as building T-600 and developing T-800 Infiltrators prior to Judgment Day in order to replace soldiers on the battlefield prior to Judgment Day. Hence, the T-800 is fully operational in the 2010s in the following T2 Saga and Salvation timelines. (While in the Original timeline, the T-800 came online on 2026.)
In the Dark Fate timeline, Skynet is replaced by Legion, who creates unique versions of Terminator, designated as "Rev" along with a number signifying what model they are, such as Rev-7 and Rev-9. These Terminators seen so far have both an Endoskeleton with a mimetic polyalloy sheath, a concept similar to the T-X. A unique ability allows these units to split into two separate units, one the endoskeleton Terminator, the other the polyalloy Terminator.
Despite Kyle Reese's claim that "cyborgs do not feel pain", a Terminator is capable of sensing injuries and that "the data could be called [pain]". Cameron was revealed to have an intolerance to some degrees of temperature in her surroundings, as humans do. Unlike humans, however, being machines, they are capable of resisting or shutting off this sense of discomfort. It is elaborated that Terminators can appreciate physical sensations such as the wind blowing through its hair and toes, and process them in a psychological manner.
Terminator Cameron states that Terminators' densities deny them the ability to swim. However, that they can survive submerged and walk along the bed to the shore.. T-H Infiltrator Prototype is able to swim possibly due to human nature he/she possesses.

- Main article: Infiltrator
The Infiltrator is a type of the Humanoid Hunter Killer that is built to look exactly like humans and used to infiltrate, seek out and kill human beings. The Infiltrator progresses from rubber skin, human flesh over its endoskeleton, to mimetic polyalloy able to mimic any person or object.
- T-600 - The first Infiltrator model that possesses a rubber skin sheath.
- T-800 - A breakthrough Terminator that uses living tissue covering for superior infiltration.
- T-8xx - Various variants of the Series 800 Terminator

- T-X - An advanced endoskeleton based on T-950 that possesses mimetic polyalloy and onboard weaponry.
- T-900 (The Sarah Connor Chronicles) - A advanced Infiltrator able to mimic humans.
- TS-300 (created by MIR) - A ceramic Terminator designed to replace specific individuals.
- T-1000 - A mimetic polyalloy Terminator capable of altering its form and appearance.
- T-3000 - A highly advanced infiltrator model. Made from infecting human being with nano-machines and having them replace the tissue of the subject.
- T-5000 - A highly advanced Terminator model. Used by Skynet to store its consciousness and infect John Connor with nano-robots and turn him into a T-3000.
- In most of the Terminator fictions, Terminators deployed in the Future War usually kill humans upon finding them. However, Infiltrators sent to the past seem to be programmed to kill only their primary targets and most of them only kill humans when needed, such as anyone who gets in their way, or those who are to be impersonated and replaced in order to get close to the targets.
- Terminators are able to detect their fellow Hunter Killers when they are nearby via transmitters.
Behind the Scenes
- James Cameron asserts that he came up with the concept of the Terminator characters on his own. However, several works of science fiction predating his film have similar concepts, including "Soldier", "Demon with a Glass Hand", "I Have No Mouth and I Must Scream", "Second Variety", "Jon's World", Cyborg, La Jetée, and Cyborg 2087.
The end credits of first three films list Arnold Schwarzenegger's characters as simply the "Terminator". Later films credit the newer Terminator characters by their series numbers, such as "T-1000", "T-X", or "T-800".
Those being chased by a Terminator, will often simply call it the "Terminator" (as Reese does throughout the first film). If more than one type of Terminator is involved, more specific names may be used, ranging from an official designation to a variety of nicknames. The most common seems to be to add "T-" to the beginning of the series number.
