Valkris

Valkris was a Klingon operative who was romantically involved with Kruge. In 2285, she obtained classified Federation data regarding the Genesis Device that she carried with her aboard the vessel Merchantman. Valkris was killed when the ship was destroyed by Kruge's Bird-of-Prey, after the Klingon commander learned that she had seen the data. Moments before her death, however, Kruge vowed that Valkris would be remembered with honor. (Star Trek III: The Search for Spock)

Valkris was played by actress Cathie Shirriff.
