Stex

General Stex was a Klingon flag officer in 2293.

Stex was one of the Klingons serving on Klinson flagship IKS Kronos One and accompanied Chancellor Gorkon, his daughter Azetbur, General Chang, Brigadier Kerla, and another Klingon general to the dinner party aboard the USS Enterprise-A following the invitation of Captain James T. Kirk. During the dinner he sat between Azetbur and Kerla.

He was present in the staterrom of Gorkon aboard the Kronos One when the two Starfleet yeomen Burke and Samno beamed aboard to assassinate Chancellor Gorkon. He was ordered to watch the door by Gorkon and lost his right arm when one of the assassins shot at him while the anti-gravity was off.

He later testified against James T. Kirk and Leonard McCoy when they were on trial for assassinating the chancellor.

Stex was also present at the Khitomer Conference and witnessed the assassination try at the Federation president. (Star Trek VI: The Undiscovered Country)

General Stex was played by actor Brett Porter.
Stex's name was not spoken in the movie, but was mentioned in the end credits.

The Star Trek Customizable Card Game gives his name as Kor'choth.
