~ Kol, thinking he was about to win his fight against Burnham.
Kol is a villainous Klingon that was first introduced in the Star Trek: Discovery pilot The Vulcan Hello.
He was portrayed by Kenneth Mitchell.
Kol was the son of Kol-Sha. By the 2250s, he led the House of Kor, one of the 24 great houses of the Klingon Empire.
As a leader of a noble house descended directly from Kahless, Kol looked down on most other Klingons, especially those who were outcasts from Klingon society. When T'Kuvma summoned the 24 great houses to a binary star system to fight the Federation, he refused to join up with T'Kuvma, promising to one day see T'Kuvma put in his place.
About six months T'Kuvma's death, Kol wanted to obtain the technology of T'Kuvma's flagship, to not only enable the defeat of the Federation, but to enable him to overthrow the current leadership of the Empire and rule the Empire himself. To that end, he pretended to acquiesce to T'Kuvma's successor Voq's leadership of the House of T'Kuvma, and to join forces with Voq.
Giving the starving crew supplies from his own ship, he was able to convince nearly all of them to turn against Voq once Voq had retrieved technology from the wreck of the USS Shenzhou that allowed them to fix the warp drive. Kol stranded Voq on board the Shenzhou, and left the area. However, T'Kuvma's lieutenant L'Rell transported over to the Shenzhou, and provided Voq a means by which to escape the wreck.
Intending to kidnap Sarek, Kol had a group of Klingons put out peace feelers to the Federation, knowing they would likely send Sarek. Sarek was seriously injured in an assassination attempt by a Vulcan extremist named V'latak before he could make it to the supposed peace conference. Admiral Katrina Cornwell went in Sarek's place. Kol decided he would have to make do with a Starfleet Admiral, and told Cornwell he looked forward to meeting her.
Later, the Discovery was able to use sensors planted on Kol's flagship by Michael Burnham to generate an algorithm that allowed the Discovery to determine the Klingon ship's position while cloaked. After the Discovery personnel were beamed back to safety, Captain Lorca had his crew fire a full spread of photon torpedoes at the ship. Roaring in the face of their impending doom, Kol and his crew died in the resulting explosion, ending Kol's plans to rule the Klingon Empire.
