Ch'Rega

Officer Ch'Rega was a female Klingon warrior who served under Kohlar during their crew's quest to find the kuvah'magh (or savior) of the Klingon race. She and the other Klingons were transported onto USS Voyager when the Klingon battle cruiser they were on developed "engine problems." She at first wished to mate with Harry Kim, but later became aroused by Neelix and had a torrid affair with him, much to the frustration of Tuvok, who was sharing quarters with Neelix at the time. She and the other Klingons settled on a new planet soon after.
