Biography
The Beast described Danny as "the little boy who lied". (TV: The Satan Pit) He worked for the Ethics Committee, a job which he found "not as boring" as it sounded, and served as its representative on the Walker Expedition in 4221. On Sanctuary Base 6, Danny observed the Ood's telepathic field, as it was "the only way to look after them". Danny introduced the Ood slave race to Rose Tyler. (TV: The Impossible Planet)
When the Ood were possessed by the Beast, Danny came up with the idea to create a psychic flare to disable the Ood and break the Beast's hold over them. When that was successful, he, Rose, Toby Zed, and Zachary Cross Flane escaped from Krop Tor on a rocket, which the Tenth Doctor towed to safety with the TARDIS when the gravity field keeping Krop Tor in orbit around the black hole, K37 Gem 5, vanished.
