T'Kar was a Klingon mercenary who worked for Verad Kalon in 2370. His partner was Yeto. T'Kar travelled with Verad, Yeto and Mareel aboard the Ekina to Deep Space 9, where his Trill employer wanted to remove the Dax symbiont from Jadzia Dax. He was opposed to the Klingon Empire's alliance with the Federation, stating that the Empire was ruled by "doddering fools and frightened old women". T'Kar and Yeto took the senior staff of Deep Space 9 hostage while the Trill symbiont was removed. He was later knocked unconscious by Odo and Kira Nerys. (DS9 episode: "Invasive Procedures")
