Henoch
From Memory Alpha, the free Star Trek reference.
Henoch was the last survivor of the rival faction to Sargon's.
In 2268, Henoch occupied Spock's body and decided that he would not give it up. He used Spock's mind meld abilities to confuse Nurse Chapel so that she would administer a worthless metabolic formula to Sargon occupying Captain Kirk's body, so that Sargon and Kirk would die. He then took control of the Enterprise. When the doctor tried to inject him with a (supposedly) deadly poison, Henoch ordered Nurse Chapel to inject the doctor. She seemed to follow this order, but as Spock's consciousness inhabited Chapel's mind, she was able to resist and inject Spock's body instead. Henoch then left Spock's body and tried to transfer to another body, but was stopped by Sargon, so his consciousness died. The injection had not really been deadly, as it was used as a ploy to drive Henoch from Spock's body. (TOS: "Return to Tomorrow")
- The name Henoch is a variation of the Biblical name Enoch.
