Golden Emperor

The Golden Emperor, also known as the Master Brain, (COMIC: City of the Daleks) was an early Emperor of the Dalek Empire. It was slightly shorter than the other Daleks, with a disproportionately large spheroid head section rendered in gold rather than grey. It also had three globes on each panel unlike other Daleks.

Origin
After the neutronic war that devastated Skaro, the mutants had survived in the casings. The only humanoid Dalek survivors of the war, Yarvelling and the warlord Zolfian encountered a Dalek which persuaded them to build more Dalek casings for their mutated descendants. Before the last two humanoid Daleks died, a special casing was built for the Emperor to reflect its new rank, made of Flidor gold, quartz and Arkellis flower sap. (COMIC: Genesis of Evil)

Rule
In 2400, the Emperor gave an address at the Great Council Chamber, ordering a Dalek invasion of the solar system. (COMIC: Invasion of the Daleks)

Residing in the Emperor's Quarters, the Emperor gave the order to switch on the revitalising rays. He was unaware that he was being observed by the human Jeff Stone, who was conducting espionage in the Dalek City. (COMIC: City of the Daleks)

Ultimately, the war ended with the Emperor being forced to sue for peace by Earth ambassadors. In a televised ceremony, the Emperor renounced the Dalek dream of conquest and promised that the Daleks would never leave Skaro again. (COMIC: Battle for the Moon)

After two hundred years of peace, a mysterious Mechanical Planet came which threatened both Skaro and Earth. The Emperor landed on Earth and made an offer to eliminate the threat in exchange for the return of confiscated Dalek weaponary, which the humans grudgingly accepted. Ultimately, the Daleks destroyed the Mechanical Planet and, with their weapons and power restored, the Emperor vowed to conquer "all the planets in every sky." (COMIC: The Mechanical Planet)

Having given him a tour of the Dalek City, the Emperor personally interogated Irishman Pat Kelley, who had arrived on Skaro in the spaceship Emerald Isle. Believing him to be a spy, the Emperor ordered all the Dalek inventions and technology, which Kelley had praised, to be screened for flaws. Interpreting Kelley's advisement for the Daleks to grow out their five-leaf clovers as an attempt at sabotage, the Emperor had his ship refitted before sending Kelley back to Earth with the clovers, believing that it would bring Earth to ruin. Little did he realise however, Kelley had infact been playing an elaborate ruse to acquire the clovers all along. (PROSE: The Five-Leaf Clover)

When the Skaro water plant was sabotaged, the Emperor initially believed that human slaves were responsible. Soon after, however, the Daleks caught an alien spy whom the Emperor ordered to be brought to him. The spy proved to be scout for an army of Birdmen that invaded Skaro. Though the invaders were ultimately exterminated, the Emperor lamented that their ability of invisibility, a potential asset to the Daleks, was lost with them. (COMIC: The Invisible Invaders)
