Episode Title: "WHOM GODS DESTROY"
Production Number: 71
Original Air Date: 01-03-69
The U.S.S. Enterprise arrives at Elba Two, a planet with a poisonous atmosphere where the Federation maintains an asylum for the few remaining insane criminals in the Galaxy. Captain Kirk and Commander Spock beam down to the colony to deliver a new medicine to treat mental illness. They learn that the newest inmate is Garth of Izar, a former starship Fleet Captain, who has used Antosian shape-shifting techniques to take over the asylum.
The peaceful people of Antos taught Garth the techniques of cellular metamorphosis to repair destroyed parts of his body when he was dying, but Garth later learned to use the techniques to assume any form. Captain Garth tried to destroy Antos Four, but his crew mutinied and Garth was sent to the asylum.
Garth has invented a powerful explosive, and plans to take over the Galaxy, but Kirk and Spock are able to overpower him and regain control of the asylum; they deliver the medicine to treat Garth and the other inmates.
Factoid: Fleet Captain Garth's exploits were required reading when Captain Kirk was in the Academy, and his victory at Axanar is still required reading.
Factoid: The Enterprise used the Cochrane deceleration maneuver to defeat a Romulan vessel near Tau Ceti. The Cochrane deceleration is a classic battle maneuver that every starship captain knows.
