What is the Dalek's ultimate goal?

The Daleks are a fictional alien race in the British science fiction television series Doctor Who. Created by writer Terry Nation, they are one of the Doctor's most persistent and deadly enemies, and have been featured in the show since its inception in 1963. The Daleks' ultimate goal is to achieve universal domination and exterminate all other forms of life, which they see as inferior to their own. They are driven by a fanatical belief in their own superiority and a desire to purify the universe of all impurities.

The Daleks are known for their distinctive appearance, which includes a pepperpot-shaped metal casing and a plunger-like arm. They are also known for their catchphrase, "Exterminate!", which they shout while firing their signature weapon, a powerful energy beam. Despite their seemingly robotic nature, the Daleks are capable of complex emotions such as hate, fear, and anger, and have been shown to be capable of deception and manipulation.

Overall, the Daleks are a classic example of the "evil alien race" trope in science fiction, and their relentless pursuit of universal domination and extermination has made them a memorable and iconic part of the Doctor Who franchise.
