The Klingon ambassador who demanded that Kirk be extradited for the death of Kruge and the theft of a Klingon ship.
Kamarag is the Klingon Empire's ambassador to the Federation. In Star Trek IV: The Voyage Home he addresses the Federation Council, playing back Kruge's last recordings and demanding that Kirk be handed over to answer for the events of the Genesis affair. His accusations cast Kirk as a criminal and help shape the charges that Kirk and his crew later face before the council.
He returns in Star Trek VI: The Undiscovered Country among the Klingon delegation travelling with Chancellor Gorkon to peace talks. He was played by John Schuck.
