Daleks

The Daleks were a warrior race (TV: The Witch's Familiar, Hell Bent) made up of genetically engineered mutants (TV: The Daleks, Genesis of the Daleks) belonging to fundamental DNA type 467-989 (TV: Daleks in Manhattan) who were originally from the planet Skaro. (TV: The Daleks) The mutants were usually encased inside armour consisting of polycarbide(TV: Remembrance of the Daleks) and the metalDalekanium. (COMIC: The Humanoids)

On many occasions, the Daleks openly acknowledged a single Time Lord, the Doctor, as their greatest enemy. (TV: The Chase) The Doctor described them likewise, (TV: Victory of the Daleks) and, in their tenth incarnation, stated that a Dalek was "not just metal, it [was] alive," that "inside that shell, there [was] a creature born to hate, whose only thought [was] to destroy everything and everyone that [wasn't] a Dalek, too." (TV: Daleks in Manhattan) The War Doctor also said that Daleks were "not robots", but "savage, incredibly intelligent, living, breathing creatures housed inside a war tank". (PROSE: The Stranger)

The Daleks fought the Time Lords in the Last Great Time War, ending in the near-total destruction of the Dalek race, (TV: Dalek) until they rebuilt their empire (TV: Asylum of the Daleks) by using a progenitor. (TV: Victory of the Daleks) Intensely xenophobic and bent on universaldomination, the Daleks were hated and feared throughout time and space.
