About 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 (Chancellor) of the Klingon Empire. 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 humorously referred to as "that crazy loon eyeball thing".
