Gold Dalek (Day of the Daleks)

On the eve of the Second Dalek War of the 26th century, a Gold Dalek, acting as Dalek Supreme, led a platoon of Daleks to meet on the Ogron homeworld. There, it ordered the Master's captives — including the Third Doctor, Jo Grant, General John Williams and the Draconian Prince — exterminated. However, the Master convinced the Daleks to leave the prisoners under his supervision until the Daleks' planned war began so he could see the galaxy in ruins, to which the Daleks agreed and left the planet. Later, the Doctor managed to escape the prison cell by using the Master's hypnosound device, which caused the Ogron on guard to perceive the Doctor as the Gold Dalek and he opened the cell out of fear.
