Ch'Pok was a Klingon advocate who prosecuted an extradition hearing on Deep Space 9 to have Lieutenant Commander Worf extradited to Qo'noS after he apparently destroyed a Klingon civilian ship and killing all 441 of its passengers. Ch'Pok sought to prove that Worf was full of bloodlust and would knowingly attack an unarmed opponent. He infuriated Worf by accusing him of killing innocent people to prove himself a true Klingon. At first Worf denied that he would do such a thing, but angered and feeling that his honor had been questioned he attacked Ch'Pok. Ch'Pok had provoked him into an attack on an unarmed opponent. Satisfied, Ch'Pok rested his case.
The ship was later determined to have falsified its sensor readings in order to appear as a transport vessel. All the supposed victims never existed. Sisko forced Ch'Pok to admit that the entire affair was staged to discredit Worf and was part of a elaborate Klingon plot to stop the Federation from escorting Cardassian freighters.
