Kunivas

From Memory Alpha, the free Star Trek reference.

Kunivas was an officer in the Klingon Defense Force in 2364 who became disillusioned by the peace in the Klingon Empire. Along with Korris and Konmel, he stole the Batris, a Talarian freighter, and was involved in the destruction of the IKS T'Acog. Kunivas was severely injured in this conflict. Though he was rescued from the damaged freighter by the USS Enterprise-D, he died soon after. (TNG: "Heart of Glory")

Kunivas was played by actor Robert Bauer.
