A Starfleet Command admiral who refuses Kirk permission to divert the Enterprise to Vulcan in 2267, an order Kirk disobeys to save Spock's life.
Admiral Komack appears in the second-season episode Amok Time. The Enterprise is due at Altair VI for the inauguration of a new president, an occasion with real diplomatic weight, when Spock's condition makes it urgent to take him home.
Kirk asks for leave to go by way of Vulcan. Komack answers by subspace that the ceremony has been brought forward and that the Enterprise is to join the other ships there without delay. Kirk goes to Vulcan anyway.
He is spared the consequences. T'Pau herself asks Starfleet to excuse the delay, and Komack grants the request. The admiral is also named in This Side of Paradise as the officer to whom Kirk reports. He was played by Byron Morrow.
