@movies_creatorr: T-850 vs T-X. In Terminator 3: Rise of the Machines, Skynet sends a highly advanced T-X terminator back in time to kill John Connor's future lieutenants—including his future wife, Kate Brewster. An older, reprogrammed T-850 is also sent back to protect John and Kate, ultimately revealing that the nuclear apocalypse (Judgment Day) cannot be stopped, only survived.
