The class of Terminator in the Future War was the T-800 , also called the Series 800, which appeared as a nearly undetectable infiltrator after 2026. The future-war setting itself is the resistance’s war against Skynet after Judgment Day.

What it means

  • The T-800/Series 800 replaced earlier Series 600 units as the more advanced infiltrator model.
  • Earlier in the war, the Resistance also faced Series 600 Terminators, but those were easier to spot because of their rubber skin.
  • In the future-war timeline, Skynet used multiple machine types, but the best-known “class” from the war scenes is the T-800.

Quick note

If you meant a specific movie, game, or timeline version, the answer can change slightly because Terminator continuity varies across versions.
