Extermination



Extermination was the goal of the Daleks, who sought to kill all other lifeforms in existence. (TV: Genesis of the Daleks) Though used synonymously with pest control or genocide, (TV: Doomsday, Evolution of the Daleks) the execution of a single lifeform could be refered to as extermination. (TV: The Parting of the Ways) The Daleks' first and foremost instrument of extermination was their personal gunstick located on their weapons platform. Before firing a fatal blast, the Daleks would typically and loudly exclaim "Exterminate!" (TV: Genesis of the Daleks)

Other words used by the Daleks synonymously with extermination were destruction, termination, elimination, obliteration, annihilation, and eradication. (TV: The Chase)

A most prolific subject of the Daleks' hatred was the Time Lord known as the Doctor. As such, most Daleks sought to kill the Doctor on sight. (TV: Remembrance of the Daleks, Dalek, Evolution of the Daleks)

Similarily, the Cybermen of Pete's World, whom the Daleks engaged in the Battle of Canary Wharf, (TV: Doomsday) sought to "delete" all those they deemed incompatible for the upgrade to cyber-form. (TV: Rise of the Cybermen/The Age of Steel) Cybermen of N-Space used eradication. (TV: Silver Nemesis)
