Black Dalek (Doctor Who and the Day of the Daleks)

A Black Dalek served as second-in-command to the Gold 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. With the Gold Dalek and other Dalek aids, the Black Daleks was a member of the High Council of the Daleks on Earth.

The Black Dalek received reports from the Controller of Earth Sector One about human resistance to the Dalek occupation. The Black Dalek referred to them contemptuously as "criminals".

When the Third Doctor threatened to negate the timeline, the Black Dalek joined the force of Daleks and Ogrons which travelled back to the 20th century to ensure the Peace Conference failed. Raiding Austerly House with the Gold Dalek, the Black Dalek and the rest of the invaders were destroyed by Shura with a Dalekanium bomb, after the conference's delegates reached safety.

The Gold Dalek does not appear until Chapter 8 of the novelisation, corresponding with early scenes from Episode 3 of the serial, in which the Daleks learn the Doctor is at large.
