The Reman Viceroy was the title of Praetor Shinzon's Reman adviser, Vkruk, during the Remans successful coup of the Romulan Star Empire's government. He served as Shinzon's lieutenant and helped him cope with his sickness through a form of telepathic healing though this only eased the pain. It is uncertain whether this title would have remained had Shinzon remained as Praetor or if the Reman government has adopted the title for its head of state. (movie: Star Trek Nemesis)
