The unnamed Klingon magistrate who presides over the trial of Kirk and McCoy for the murder of Chancellor Gorkon in Star Trek VI and sentences them to Rura Penthe.
The judge presides over the show trial of James Kirk and Leonard McCoy on Qo'noS in Star Trek VI: The Undiscovered Country. Seated high above the accused, he keeps order in the roaring courtroom by pounding a heavy clawed sphere on the bench.
General Chang prosecutes and Colonel Worf defends. Once Chang has used Kirk's own log entry and his admission of responsibility for his crew against him, the judge finds both men guilty.
He then announces that, in the interest of good relations at the coming peace conference, the death sentence is commuted to life in the dilithium mines of Rura Penthe, a place from which nobody returns. The part was played by Robert Easton.
