The Time Eaters were beings that fed on time.
Some of them were trapped in orbit around the event horizon of a black hole. They were able to contact Elliot Payne on 19th century Earth. In exchange for his help in freeing them, they promised to bring his dead wife Shania back to life. However, they could not really do this and were using Payne so they could escape and eat time across the universe. Their plan was stopped by Leela, Henry Gordon Jago and George Litefoot.
