The Doctor runs into Leela on a planet inhabited by two races which, of course, are fighting a war with each other. Leela immediately recognizes the Doctor as the God of Evil in her races cosmology, I wonder why no one has recognized him before? You would think that because their relationship had got off to this shakey start that not much progress would be made, but Leela eventually comes along with the Doctor and stays for about a year until "The Invasion of Time."
Leela definitely isn't a screamer, she's a highly skilled knife fighter that you don't want to mess with. The only problem she has with the Doctor is that he doesn't let her kill enough people.
Leela is played by Louise Jameson (born April 20, 1951 in Wanstead, London)
