The Klingon commander of the M'Char, who stops and attempts to search Kasidy Yates's freighter in 2372 and is executed for backing down when Sisko intervenes with the Defiant.
Kaybok is a Klingon officer who appears in The Way of the Warrior, the feature-length opening of Deep Space Nine's fourth season. He belongs to the task force that General Martok has brought to the station, supposedly to help defend against the Dominion.
Acting on orders to look for changelings, Kaybok halts the freighter Xhosa in Bajoran space and prepares to board it. Sisko arrives in the Defiant and tells him that searches of neutral shipping will not be allowed, and Kaybok, unwilling to fire on an ally, withdraws.
Martok later informs Sisko that the commander has been put to death for disobeying his instructions. The incident is an early sign of how far the Klingons are prepared to go.
