Played by Christopher Plummer
Chief of Staff to Klingon Chancellor Gorkon. A proud warrior, Chang was also fond of quoting Shakespeare and other luminaries. Chang feared the changes that peace would bring and conspired with Starfleet Admiral Cartwright and others to assassinate Gorkon in an effort to block Gorkon's peace initiative. Chang was killed at Khitomer when attempting to disrupt the peace conference there in 2293. (Star Trek VI: The Undiscovered Country)
NOTES: In addition to Chang's Shakespearean quotes, his demand in court that Kirk answer a question without waiting for a translation is a paraphrase of American Ambassador Adlai Stevenson, who made the same demand of Soviet Ambassador Valerian Zorin at the United Nations during the Cuban missile crisis in 1962.
