Captain Ganok, son of Ganthet was an officer in the Klingon Defense Force during the Dominion War.
In 2375, he was the captain of the IKS Ro'Kronos when he rescued Klag from Marcan V, congratulating him on his successful battle against the Jem'Hadar and naming him the "Hero of Marcan V." (GKN - Tales of the Dominion War short story: "A Song Well Sung")
