Henoch
Star Trek: The Original Series
Episode: TOS 051 - Return to Tomorrow
Henoch to Thalassa: Stay put
One of three advanced beings who survived a devastating war that destroyed their planet 500,000 years ago. His consciousness, along with that of his old nemesis Sargon and wife Thalassa, was encased in a receptacle stored in an underground vault, and discovered in 2268 by the U.S.S. Enterprise. Spock allowed Henoch's mind to "borrow" his body so that Henoch could construct android bodies for himself and the others. Henoch, however, was unable to leave behind his old hatreds, and tried to destroy Sargon and Thalassa before being destroyed himself.
