Yes, We’re talking about the Daleks, the most evil creatures ever invented.
Listening to the sound affects in this audiobook version of Genesis of the Daleks really does bring home the fear of the Daleks you once had as a child.

Tom Baker narrates an abridged version of this 1975 television adventure in which the Doctor. Sarah and Harry are sent to Skaro, home world of the Thais and the Kaleds. As a thousand year war of attrition reaches its climax, the crippled scientist Davros has created protective casings for the genetic mutations which his race will become. Only the Doctor knows what fear and misery these ‘Daleks’ will inflict upon the Universe – but with time running out, can even he prevent the birth of such evil?

Travelling in their time and space machine, the Tardis, the Doctor and co. began their adventures on November 23rd 1963 by voyaging 100,000 years into Earth’s past to help some slightly dim cavemen discover fire.
