A common Skynet tactic is to have a Terminator impersonate another human or Terminator's voice or appearance.

Most Terminators seem to have the ability to perform vocal impersonations. Terminators utilizing mimetic polyalloy - including the T-1000 in Terminator 2, the T-X in Terminator 3, and the T-1001 in Terminator: The Sarah Connor Chronicles - are able to impersonate both the voice and the appearance of other humans.

Vocal impersonation

Vocal impersonations have been used in all four Terminator films and the TV series:

  • The T-800 did a vocal impersonation of Sarah Connor's mom while talking to Sarah. While doing the impersonation, the T-800 was able to convince Sarah to give her the phone number of the Tiki Motel. The Terminator
  • The T-800 did a vocal impersonation of a police officer (1L19) during pursuing Sarah Connor. The Terminator

Mimetic polyalloy impersonation

The physical impersonation strategy has been used in Terminator 2: Judgment Day, Terminator 3: Rise of the Machines, Terminator Genisys and Terminator: The Sarah Connor Chronicles. It was not used in The Terminator, as mimetic polyalloy Terminators had yet to be sent back in time, nor in Terminator Salvation, as mimetic polyalloy Terminators had yet to be built.

Machine phase matter impersonation


T-3000's disguise as Detective Cheung is revealed.

The Machine phase matter allows any human converted into a T-3000 to change the outer appearance for infiltration.


  • Impersonation is a short-term tactic; this differs from the long-term strategy where a Terminator replaces a human for long periods of time.
  • Guardian states that " As a T-800, I lack the mimetic skills to appear as anyone else." This means that while the T-800 can interface with mimetic polyalloy, changing the outer appearance to something other than its Model is too complex for its CPU.
