K'muc

In the mirror universe, K'muc was a $𝜇$ captain in the Klingon-Cardassian Alliance. In 2371, commanding the Imperial Starship Mek'leth, he confronted a $𝜇$ that had destroyed a Klingon outpost near $𝜇$. Refusing to believe that resistance was futile, K'muc fought valiantly, but the Borg quickly adapted to the Klingon weapons. The Borg surgically dismantled the Mek'leth with tractor beams, killing K'muc and his subordinates. (TNG novel: The Worst of Both Worlds)


 * K'muc was probalby the first Klingon to make official contact with the $𝜇$ in the mirror universe.
