Supreme Dalek (The Magician's Apprentice)

The Supreme Dalek was the leader of the Daleks on Skaro in the Dalek City.

He was the Dalek that made all the greater decisions involving the Daleks and he was the one who told the other Daleks to go assist Davros as he pleaded for help, and he was also the one to lead the conversations. He ordered the Extermination of the Twelfth Doctor after he had stolen Davros' wheelchair and mocked the Daleks, however it failed.

He was the Dalek who took the privelege of Exterminating and Clara Oswald when they were captured and brought to the Daleks. He however ordered for a beamer to destroy the TARDIS.

When the Daleks from the sewers began to rise above to the city itself and destroy the Daleks in it in anger and revenge he yelled for the Doctor to help them. He was ultimately destroyed by the angry decaying Daleks. (TV: The Magician's Apprentice/The Witch's Familiar)
