Gold Dalek (Day of the Daleks)
From Tardis Wiki, the free Doctor Who reference
A Gold Dalek served as the Supreme Dalek in charge of the planet Earth in an alternate timeline where the Second World Peace Conference had failed and the Daleks invaded in the 22nd century in the aftermath of the devastating wars which followed. When the Third Doctor threatened to negate the timeline, the Gold Dalek led the Daleks and their Ogron servants back to the 20th century to ensure the Conference failed. They advanced into the Auderly House which was then destroyed by Shura using a Dalekanium bomb, taking them with it. (TV: Day of the Daleks)
