K'zeq was a male Klingon who served as a commander of the Klingon prison facility on planet Pao'la between 2279 and 2281. During this time, he was responsible for several survivors of the USS Gagarin who had been taken prisoner in 2279. Two of those prisoners, Captain Gralev and Ensign Randall Bird, died during his tenure, the latter because K'zeq denied him proper medical treatment for a flu Bird had contracted.
