Legion of the Beast
The Legion of the Beast was how the entire Ood stock of Sanctuary Base 6 identified themselves whilst possessed by the Beast of Krop Tor, serving as his eyes and ears. They were led by the Beast himself, who would talk through]] them as well as personally taking possession of the body of Toby Zed, a human crew member. The size of the Legion was fluid, the Beast noting that "the Legion shall be many, and the Legion shall be few", and vowing that his Legions would swarm across the worlds.
The Ood were freed from the Beast's possession when he was destroyed by the Tenth Doctor, with Rose Tyler being forced to eject the possessed Zed into space. Much to his regret, the Doctor was unable to save the Ood as they perished when Sanctuary Base 6, along with the planet Krop Tor, fell into the black hole K37 Gem 5. The lost Ood were acknowledged as deceased with honours by the surviving crew of Sanctuary Base 6.
