Gowron

Gowron, son of M'Rel is a fictional character who appeared in the American science fiction television series Star Trek: The Next Generation and Star Trek: Deep Space Nine. Portrayed by Robert O'Reilly, he is the leader of the Klingon Empire, known as the Chancellor. O'Reilly had appeared earlier in The Next Generation as Scarface in the second season episode "Manhunt", and was cast as Gowron due to his comedic ability and his piercing and extremely unsettling gaze, or what O'Reilly himself amusing referred to as "that crazy loon eyeball thing".

Appearing first in "Reunion", where he was named Chancellor, Gowron went on to cement his position against the challenge of the Duras family in the two part episode "Redemption". Following the advice of Lt. Worf (Michael Dorn) in "Rightful Heir", he incorporated the clone of Kahless into the Klingon government without disrupting his own leadership. In Deep Space Nine, he brought the Klingons into a conflict with the Federation over fears that the Cardassians had been infiltrated by the Founders. After Cardassia sides with the Dominion, he allies with Starfleet throughout the rest of the war. However, he later grows jealous of the success of General Martok (J. G. Hertzler), resulting in his death at the hands of Worf.
