Star Trek TOS Season 2 1967-1968 (1970, UK)

This season saw Ensign Pavel Chekov added to the regular bridge crew. Although his first appearance in "Catspaw" had him operating the science station, "Friday's Child" established him as the ship's primary navigator.

The Klingons returned, appearing in three episodes, establishing them as major adversaries. The Romulans also made a brief reappearance in "The Deadly Years" while Harry Mudd returned for a second tussle with the Enterprise crew in the comedic episode "I, Mudd". "Mirror, Mirror" saw Kirk and company paying a first visit to the mirror universe.

The show began to explore the rest of the Federation, with the Enterprise making its first trip to Vulcan as Spock underwent Pon farr in "Amok Time". "Journey to Babel" saw the Enterprise transporting representatives of the Vulcans, Andorians, and Tellarites to a conference to admit the Coridans to the Federation, among them Spock's father Sarek. "Obsession" provided an insight into Kirk's early Starfleet career, revealing some of the details of his tour of duty on the USS Farragut.

Regular crewmembers began to appear more. Scotty was firmly established as the Enterprise's third-in-command, given a spotlight in "Wolf in the Fold", in which he was accused of a series of murders. Chekov and Uhura were given a chance to accompany Kirk on an away mission in "The Gamesters of Triskelion" and Chekov also had a prominent role, and an opportunity for romance, in "The Apple".

The Enterprise visited several planets based on Earth history, either by coincidence or as a result of Human visitors, such as Ancient Rome ("Bread and Circuses"), Chicago gangsters ("A Piece of the Action"), Nazi Germany ("Patterns of Force") and the American Constitution ("The Omega Glory"). There were other surprising encounters with Zefram Cochrane, the father of warp technology ("Metamorphosis"), the Greek god Apollo ("Who Mourns for Adonais?") and a giant space amoeba ("The Immunity Syndrome").

The show continued Gene Roddenberry's original idea of political fables, with two episodes identified as providing somewhat opposing commentary on the Vietnam War.

The season closed with "Assignment: Earth", a back door pilot for a proposed spin-off series which saw Kirk and Spock encountering Gary Seven, a man employed by mysterious aliens to watch over 20th century Earth.
