Biography
According to the Beast, he was a liar. 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, which Rose was unimpressed by. (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.
