Zaroff
Professor Zaroff was a scientist who lived during the 20th century. He was well-known for producing cheap food from the sea. He went missing, and was reported as dead, but in reality he had found the submerged city of Atlantis and was living there.
When the Second Doctor and his companions were about to be sacrificed to the Atlantean goddess Amdo, the Doctor sent a note to Zaroff. Zaroff was intrigued and put a halt to the sacrifice. He put Ben, Polly and Jamie to work and took the Doctor to his laboratory. He told the Doctor about his plans to raise Atlantis from the sea.
The Doctor found out that Damon was going to operate on Polly and turn her into a fish person. The Doctor told a servant girl named Ara to rescue Polly at the first chance she got. The Doctor cut off the power to Damon's lab. Damon came to complain to Zaroff and Ara rescued Polly. Zaroff found the Doctor had cut of the power to Damon's lab, which the Doctor called a "accident". This made Zaroff suspicious of him and to keep him close.
Zaroff explained his plan to the Doctor, which involved draining the ocean. He knew his plan would destroy the world, which was, as he saw it, the scientist's ultimate dream of power.
Atlantis's leader, Thous, betrayed the Doctor and Ramo to Zaroff, who ordered them to be sacrificed. They were rescued by the Doctor's companions, and kidnapped Zaroff to stop his plans. Zaroff faked a heart attack and grabbed Polly to use as a hostage. Polly was rescued by Jamie but Zaroff escaped, killing Ramo. He then shot Thous and his guards, claiming the rule of Atlantis for himself. He boldly proclaimed, "Nothing in the world can stop me now!"
Zaroff tried to start his experiment, but the Doctor flooded Atlantis, and Zaroff was trapped in his laboratory. He drowned. (TV: The Underwater Menace)
