A Starman is a cosmic being with a primitive conscience which might be created during the collapse of a star and exists in several different dimensions simultaneously. They consume stars and planets, and travel through time and space with the energy drained from them. The Starman's physical appearance is huge but ethereal, and its apparent form may range from humanoid to amoeboid and anything in between depending on the planets it has absorbed. They may also show up with the appearance of two separate but identical beings moving in union. Once escaping from its own time, a Starman can become a very destructive force, strolling through the universe, rewriting both history and the laws of science. The Doctor acknowledges them as a kind of gods. It was one of the Time Lords duties to protect the universe from these creatures.
