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 Dalek s , with a disproportionately large spheroid head section rendered in gold rather than grey . It also had three globes on each panel unlike other Daleks . History . 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 ray s . 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 planet s in every sky . " ( COMIC : " The Mechanical Planet " ) Having given him a tour of the Dalek City , the Emperor personally interogated Irish man 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 clover s 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 slave s 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 .
