The Beast (The Impossible Planet)


 * For the parasitic species of the same name, see The Beast.

The Beast was a colossal demon locked away in the heart of planet Krop Tor. He said that he had many names, including Satan, and claimed to be the essence of all Devil-like figures in religion and myth. He also claimed to have been imprisoned since before the universe.

Physical form
When the Doctor encountered him, the Beast resembled a gargantuan crimson horned figure with a corpse-like face, bound by chains. While possessed by the Beast, its hosts had eyes with crimson irises.

Powers and abilities
The Beast could manifest himself through electronic media, including computer voices and, crudely through hologram viewers. Its mind could leave its body and possess a single hive mind of the Ood collectively or a single Human individually, though not more than one at one time. He had the power of telepathy and, through a host, telekinesis. Possession of a human subject affected the host's skin, causing strange markings to appear all over their face and body; and vocal chords, allowing them to speak with different pitches simultaneously. Whether a single human or a hive mind, the eyes of those possessed by the beast glowed a fiery red. The Beast could also project fire from his mouth. His hosts could also physically survive in a vacuum indefinitely. (DW: The Impossible Planet / The Satan Pit) The Doctor realized that the Beast, or the Devil, or Satan was "an idea in the minds of men", and not a physical form, and that is why it could manifest into others, and could survive indefinitely after the destruction of its body.

History
Though the exact circumstances are unknown, it is known that the Disciples of the Light confined the Beast to the planet later known as Krop Tor and placed the planet in orbit around the black hole K37 Gem 5. If he ever tried to escape, the field holding the planet in orbit would break and the planet would be sucked into the black hole.


 * ''The Beast claimed to have existed before the Universe, a claim the Doctor found difficult to accept. He may have originated in the previous Universe.

The Beast spread his influence throughout the cosmos. He claimed that the devils and demons that appear in various religions were based on him. (DW: The Impossible Planet / The Satan Pit)

The Beast had a son known as Abaddon. (TW: End of Days)


 * Some also called the Beast itself Abbadon. The Beast had an unknown relationship with the Ood, who said that they served as his "Legion". This is possibly only because they were the only ones who were unable to resist the Beasts presence, and it is probable that The Legion is simply a phrase to refer to all servants of The Beast.

The Beast possessed Toby Zed, a crew member of the Walker Expedition Sanctuary Base 6, via the text transcribed into the Krop Tor Notebook.

Through Zed, the Beast's first action was to kill Scooti Manista by breaking one of the windows (the Beast and those he possesses can survive in a total vacuum indefinitely). The Base's Ood were taken over. Upon the Ood's defeat, the Beast planned to escape by keeping his spirit in Toby's body, leaving his physical body behind. The Doctor deactivated the force holding Krop Tor in orbit.

The Beast's original body was destroyed when Krop Tor fell into K37 Gem 5 and his spirit is believed to have been destroyed when Toby's body was pulled into K37 Gem 5, although he claimed that he would never be truly destroyed. (DW: The Satan Pit)
