Cheetah Planet

"Welcome to my new home, Doctor"

- The Master (Tremas)

The Cheetah World was a mysterious sentient planet and home to the Cheetah People and Kitlings.

Features
The Cheetah planet has rough terrain featuring rocks and sand. Due to the Cheetah People and Kitlings living there, it is covered in bones of dead humans and other creatures in the galaxy. It has a few hills and mountains in it as well and ruins of houses that a civilisation also used lies here decaying. The Planet was also described by the Master as being covered in Artron energy.

Life forms
The Cheetah People where the dominant species there along with the Kitlings who the used as part of there teleportation powers. They do ride horses but it remains to be seen if the horses evolved on the planet or where taken from another planet. (DW: Survival)

Sentience
The planet was in some sense, sentient and empathic and is connected to the Cheetah People. When the Cheetah People fight, the planet became unstable and starts to destroy itself. The water on the planet has healing properties to the Cheetah People. The World allowed the Cheetah People to teleport to other planets to bring back prey. It also allowed people who wished to come home enough to return there by teleportation. Near-Humans such as Humans and Gallifreyans slowly begin to metamorphosize, turning aggressive and physiclly changing into Cheetah People. The Master described the world as dying because of the aggression of its inhabitants. (DW: Survival)

History
At some point before the 20th century, an unknown civilization tried to conquer the planet. They bred the Kitlings to be their eyes and thought they could control the planet, but they were wrong. They too were turned into Cheetah People, leaving only the ruins scattered around the landscape.

During a physical struggle between the Doctor and the Master, earthquakes shook the planet, implying that it may have destroyed itself, though the Doctor told Ace that she still carried the planet inside her. (DW: Survival)
