Klingon advocate who prosecuted an extradition hearing on Deep Space 9 in 2372, in which Worf was accused of intentionally firing on an unarmed Klingon transport vessel and killing all its passengers. During the trial, Ch'Pok seemed to be succeeding in showing that Worf was full of bloodlust and would knowingly attack an unarmed opponent. But new information uncovered by Odo and presented by Worf's counsel, Captain Sisko, showed that the entire incident was staged, and Ch'Pok was forced to admit it was possible that the Klingon government was trying to frame Worf and discredit the Federation. Upon that admission, the trial ended.
Ch'Pok had a son, Katogh, who served in the Klingon Defense Force.
