From a planet bereft of life for half a million years, the Enterprise hears the voice of Sargon, who is able to control the ship and tells them to transport to specific coordinates which target them to a subterranean chamber. The away party consisted of Kirk, Spock, McCoy and astro-biologist Ann Mulhall; the security guards they planned to take along were prevented from de-materializing. Sargon is one of only three survivors of the planet's intelligent race - pure energy, matter without form. They tell the away party that they once started life on Earth and many other places. Suddenly Sargon possesses Kirk's body, saying he requires Spock and Ann Mulhall's bodies, too, in order to give the only other survivors of his race new life. He promises the bodies will be returned after they build superior mechanical robots as their definitive bodies, then leaves Kirk's and allows them to beam up and freely make up their minds. McCoy isn't tempted by curiosity and potential benefits, but Kirk ... Written by KGF Vissers

Sulu: The reading's growing stronger, Captain. Coming from a star system directly ahead.
Uhura: It's not a signal, sir. It does not seem to even exist, and yet it's affecting all my channels.
Capt. Kirk: [addressing Mr. Spock] Well?
Mr. Spock: Someone - or some *thing* - is attempting to attract our attention.
Capt. Kirk: "Someone or something" has succeeded. Our distress signal relays have been activated. We've been given a direction to follow, but how? What's causing it?
Mr. Spock: I do not know. Not even a Vulcan can know the unknown, Captain. We are...

Sargon Needs 3 Human Bodies
11 January 2017 | by Rainey-DawnSee all my reviews

Season 2, episode 20. The Enterprise receives a distress call from a lifeless planet. They enter into a zone that has never been explored by humans nor anyone else. Sargon communicates telepathically and wants Kirk, Spock and Dr. Ann Mulhall to beam down... McCoy wants to join for medical interests and Kirk has 2 security guards on the transporter to join them when they beam down. Sargon does not allow the 2 security guards to beam down but allows McCoy to beam down. Sargon takes over Kirk's body and also wants Mulhall and Spock's bodies as well for his wife and friend so they all 3 can live again. They want to construct robots to but themselves in and need to be in physical form to do so - that is their need for the bodies. They do not want the ship's crew to do it because they do not have the knowledge to construct exactly the android bodies they want. Sargon leaves Kirk's body leaving him with some knowledge of who and what Sargon's kind are. Kirk and crew are given a choice to help or not... if they refuse to help they are free to leave. McCoy protests helping the aliens because of the danger involved but finally agrees to it. Now Kirk, Spock and Mulhall are suspended while the aliens take over their bodies to do what they must do in creating their new android bodies but they love being in a human form but there are medical complications involved all except Henoch in the Vulcan body. It is Henoch that is the "evil" one.

Interesting concept for an episode. Spirits taking over the bodies of the 3 while the spirits or souls of Kirk, Spock and Mulhall are in a state of suspension.
