An official of the Eminiar Union's High Council and aide to Anan 7, who helped administer the computer-fought war with Vendikar when the Enterprise arrived in 2267.
Sar 6 appears in the episode A Taste of Armageddon. He is among the councillors who receive Kirk's landing party on Eminiar VII and who monitor the war room where simulated attacks from Vendikar are tallied and casualties assigned.
When the computers register the Enterprise as destroyed in a fusion bomb strike, he assists Anan 7 in the effort to make the crew report to the disintegration chambers within the day, including the deception that lures Ambassador Fox down to the planet.
He is in the council chamber when Kirk and Spock seize control and destroy the war computers, ending five centuries of tidy slaughter and forcing the council to choose between real war and peace talks. He was played by Robert Sampson.
