Doctor Who

Fourth Doctor

The Doctor is a Time Lord from Gallifrey, an ancient and advanced civilization. He stole a Type 40 time capsule to explore time and space, often accompanied by a companion, and uses his intellect to resolve adversity. Like all Time Lords, he can regenerate, changing his physical appearance and personality to survive fatal injuries. In his fourth incarnation, he left U.N.I.T. to travel freely, becoming a fearless and flippant bohemian known for his oddball humor even in danger.
