Randy tried to stop him, but as a skeleton, it soon became clear he couldn't be harmed. He returned to his lab, and took Howard. He revealed he though he was Viceroy, as Howard was dressed as him, at the time.

Randy and the real Viceroy confronted him in his lab, having activated the doomsday device, and took Randy on with a laser staff. Randy managed to stop him, by removing his head, thus disabling him. However, Viceroy was unable to stop the doomsday device. At that moment his wife arrived, and managed to convince Jerry not to destroy the world.
