The 24-episode final season of Star Trek began in September 1968 with "Spock's Brain." Season three also includes "The Tholian Web", where Kirk is trapped between two universes; this episode would be revisited in the 2005 two-part episode "In a Mirror, Darkly" from the prequel series Star Trek: Enterprise. The series' final episode, "Turnabout Intruder", aired on June 3, 1969, but Star Trek would eventually return to television in animated form when Star Trek: The Animated Series premiered in September 1973.
