In the mirror universe, Colonel Gowron was a Klingon male in the service of the Klingon-Cardassian Alliance during the 24th century. He was a firm and outspoken opponent to cross-species breeding. As part of this agenda, he sent a Terran slave to assassinate B'Elanna, the half-Klingon, half-Terran Intendant of Ardana, in 2371. The slave was unsuccessful and was himself killed by B'Elanna's personal aide Kate Janeway. (VOY - Mirror Universe novel: The Mirror-Scaled Serpent)
