Nayrok was a male Angosian who was the Prime Minister of Angosia III in the 24th century.
In 2366, he represented his people in applying for Federation membership, and was answered with a visit from the USS Enterprise-D. However, a major incident occurred in which one of the Lunar V prisoners, Roga Danar, escaped on a transport. Nayrok and Zayner requested assistance from the crew of the Enterprise in apprehending Danar. He was captured on the Enterprise and escaped again, but not before the crew learned of his background as a genetically-engineered and psychologically altered soldier. When Captain Jean-Luc Picard attempted to speak with Nayrok on the matter, Nayrok refused to cooperate on the basis that it was a matter of internal security, which obliged Picard to comply.
Nayrok was soon confronted directly by Danar when he managed to use another transport to free other prisoners of Lunar V and invade the government building in a full insurrection. Nayrok called Picard for help, however, Picard, disgusted at Nayrok's hypocrisy, declined to involve Starfleet further in what he pointed out Nayrok earlier insisted was clearly an internal matter other than to note that his official report will include the blatant systematic sentient rights violation discovered, which means Angosia III's application will be refused. With that Picard and his crew left Nayrok, horrified that he inadvertently given the Starfleet officer a clear rationale to abandon him, and the Angosian government to come to an accord with the veterans on their own. (TNG: "The Hunted")
Nayrok was played by veteran Trek actor James Cromwell.
