Anka

From Memory Alpha, the free Star Trek reference

Anka was a Troglyte laborer and member of the revolutionary group known as the Disrupters on the planet Ardana. When Vanna beamed down to the mines with Captain Kirk, he helped subdue him. He wanted to kill Kirk, but was ordered by her to alert the other Disrupters to keep a look out for any people trying to rescue Kirk. (TOS: "The Cloud Minders")

Anka was portrayed by Fred Williamson.
