M'kar

M'kar was a Klingon commander in the late 23rd century. Circa 2269, M'kar dueled with a subordinate officer, Krong, who was attempting to earn a promotion to first lieutenant. However, M'kar was distracted during this fight -- reportedly by a female, Sharjara -- and was slain in a dishonorable fashion. After his death, Krong was exiled, and no one attempted to avenge M'kar's death. (SS TOS (Where Everybody Knows Your Name))
