Daleks

Daleks are robots from the planet Skaro. They are a powerful race, bent on universal conquest and domination and completly without pity. They have had every other emotion apart from hate removed from them. They are mortal enemies of the Doctor. Their famous catchphrase "Exterminate!" is screeched whenever they are about to kill someone or something with their death ray. They are designed to look like human sized salt-and-pepper shakers. Alot of people take to hiding behind the sofa when the Daleks come on the TV.

Unlike most people think, Daleks aren't remote controled. People are actually inside the Daleks, making them move by walking around. Gethin Jones, former Blue Peter presenter, played a Dalek in 'Stolen Earth' being the Dalek that walked behind Sarah-Jane, Mikey and some other hostages.
