Fisher King
From Tardis Wiki, the free Doctor Who reference
The Fisher King was an alien warlord who conquered Tivoli and ruled it for ten years. However, the planet was eventually liberated by the Arcateenians. He apparently died and his body was transported to Earth in 1980 by the Tivolian funeral director Albar Prentis. However, he was still alive and planned for his people to recover him by turning people into ghosts transmitting coordinates to Earth. He first killed Prentis, who would become a ghost in 2119. He was tricked by the Twelfth Doctor, who blew up a dam. The Fisher King was caught in the flood and killed. (TV: Before the Flood)
