Abomination

Abomination was a term given by the Daleks to beings that were abhorrent to them.

Among the beings given this appellation were the Special Weapons Dalek, said to be insane; (PROSE: Remembrance of the Daleks) the Overseer due to his non-Dalek motives and his impurity to the Dalek Race, (AUDIO: Planet of the Ogrons) the Bad Wolf entity; (TV: The Parting of the Ways) Dalek Caan after he saw time itself; (TV: The Stolen Earth) and a Dalek mutant that had been genetically altered to be passive and benign. (COMIC: The Only Good Dalek)

When the Tenth, Eleventh, and Twelfth Doctors met, the Tenth called the event by this name, to which the Twelfth Doctor pointed out its Dalek origins and saying, "Nice." (COMIC: Four Doctors)
