"The Terratin Incident" is the eleventh episode of the first season of the animated science fiction television series Star Trek. It first aired in the NBC Saturday morning lineup on November 17, 1973, and was written by American screenwriter Paul Schneider[note 1] who had previously written the Original Series episodes "Balance of Terror" and "The Squire of Gothos". It came from a one-paragraph story idea by Gene Roddenberry based on Gulliver's Travels.[1]

In this episode, after an apparent attack, the crew of the Enterprise find themselves beginning to shrink in size toward the point that they will no longer be able to control the ship.


On stardate 5577.3, while observing a burnt-out supernova, the Federation starship Enterprise picks up a strange message transmitted in a two-hundred-year-old Earth code.

The signal is traced to a nearby planet. When the Enterprise enters orbit, it is hit by an energy beam that damages its dilithium crystals and makes the crew begin to shrink (and apparently their clothing has also shrunk, because they are organic). The cause is the inhabitants of a miniature city called Terratin. Terratin is a lost Earth colony; its inhabitants have mutated, because of the supernova's radiation and are now all microscopic size. Chief Medical Officer Dr. McCoy determines that the crew will continue to shrink beyond their ability to control the ship unless a cure is found.

Captain Kirk beams down to the surface and finds that the transporter can reverse their size. Kirk returns to the ship, but the crew are now microscopic. Meanwhile, the Terratins have beamed the bridge crew down to their city, where the crew learns the Terratins' fate. The crew are beamed back to the ship and return to normal size. However, the Terratins have been small for generations and cannot be restored to normal size. Their planet is in peril from massive volcanic activity, so the whole Terratin city is beamed aboard the Enterprise, and moved to another planet.
