Dalek Prime

The Dalek Prime was the first Dalek ever. Calculating and ambitious to the point of hubris, he became the first and most lasting Dalek Emperor and inhabited a variety of casings throughout Dalek history, most notably alternating between huge tower-like structures in throne rooms, and mobile golden casings with enlarged, bulbous dome sections. Due to this latter peculiarity, he was sometimes known as the Gold Dalek or the Golden Dalek, or as his race's Master Brain.

As the Dalek Emperor, he ruled the planet Skaro and the Dalek Empire, and was the first Emperor of the Daleks the Doctor encountered. The Emperor was an enormous, immobile, conical shell installed into a corner of the control room in the Dalek City, connected to the wall by tubes and cables, and spoke in a deep, echoing voice. Unlike the rest of his race, he had no gunstick and no sucker arm. He successfully conquered Mutter's Spiral centuries after the 36th century, in what was known as the Second Great Dalek Occupation, until he was usurped by Davros as Dalek Emperor. After leading the Renegade Dalek side of the Imperial-Renegade Dalek Civil War from the shadows, he returned to Skaro triumphant, only to be killed some time later.

He was resurrected by the Dalek Time Strategist during the Last Great Time War to lead the Empire once more, creating the Cult of Skaro. After his warship fell through time at the end of the Last Great Time War, the Emperor created a new Dalek army out of dead humans, though he and his hybrid Daleks were destroyed by the Bad Wolf at the Battle of the Game Station.

Origins
According to one source, the Daleks were originally a race of blue humanoid men. One of them, a scientist named Yarvelling, created a "machine" as a weapon. After asteroids caused the eruption of neutronic weapons owned by the Daleks, those caught in the blast were mutated. The only humanoid Dalek survivors of the war, Yarvelling and the warlord Zolfian, emerged from hiding and encountered the machine that Yarvelling had built being occupied by one of the mutants. As they died from radiation poisoning, they agreed to make more machine cases for the mutated Daleks. The original Dalek was built a new casing, made of Flidor gold, quartz and Arkellis flower sap. The first Dalek Emperor was now in command. (COMIC: Genesis of Evil)

According to other accounts, the Dalek Prime was the earliest Dalek in existence and the one that fired on Davros when they turned on him at their creation. (TV: Genesis of the Daleks; War of the Daleks) The Dalek Prime was responsible for the advancement of the Dalek race, and the Prime became the ancestor of numerous Daleks. (PROSE: The Evil of the Daleks, War of the Daleks)

Rise to Emperor
Following the end of the Thousand Year War, the Dalek Prime began conducting experiments on other life-forms on Skaro, creating mutations which went on to inhabit the petrified jungle and the Lake of Mutations near the foot of the Drammankin Mountains. Eventually the Dalek Prime discovered the molecules that had the ability to cause further mutation within a Dalek and created a drug from its research which would initiate the mutation. Not prepared to test the drug on any Dalek in case it grew beyond its capabilities, the Dalek Prime used the drug on himself and evolved to the peak of Dalek evolution with hugely enhanced mental powers and he proclaimed himself the Emperor of the Dalek race. (PROSE: The Evil of the Daleks)

According to a diffrent account, the future Emperor of the Daleks used to be "Genetic Variant Two-One-Zero", one of several genetically-modified Daleks sent to pass an ordeal. On the planet Shade, he had to collaborate with Steven Taylor to survive the Chaons that infested the planet and to get to a transmat station to escape. During the whole ordeal, Two-One-Zero exhibited qualities unusual for Daleks: he tried to save human prisoners' lives and exterminated another Dalek to save Steven's life. He promised to give Steven a transmat code to return back to the First Doctor and Vicki on the planet Entropica, but betrayed Steven in the end, giving him transmat coordinates that would lead him to certain death had he not been saved by the First Doctor. Upon returning to Skaro, Two-One-Zero demonstrated that he was indeed a superior Dalek as he was the only genetic variant to return from the ordeal. He was transferred to a new casing and declared himself the Emperor of Daleks, his experience with Steven prompting him to search for the Human Factor as a way to achieve total Dalek domination over the universe. (AUDIO: Across the Darkened City)

Early empire
Originally, the Dalek Prime and the Black Dalek Leader officially held the offices of Dalek Emperor and Warlord, respectively, on the basis of an election. Every Skaro-year, all the Dalek Commanders would convene in the Dalek City and choose whether to re-elect their two leaders. (COMIC: The Secret of the Emperor) At one point in their history, the Dalek Prime sent a squad of Daleks in a time machine to pursue the TARDIS and kill the First Doctor and his companions. The Supreme Dalek supervised the operation and was to report their progress to the Dalek Prime. The squad ultimately failed. (PROSE: The Chase)

Speaking in the City Centre, the Emperor brought up the issue of metal fatigue slowing the space conquest programme when inventor Zeg announced that his metalert was the key, demanding that he be made the new Emperor on the basis of his greater strength. Outraged by Zeg's challenge, the Emperor summoned the Black Dalek Leader to test Zeg's claim of invincibility, finding that even his gunstick could destroy him. As popular support moved to Zeg, the Emperor put the matter to the Brain Machine, which declared that Zeg must prove his intelligence and the Emperor must prove his strength in a duel for leadership.

The following day, the Emperor and Zeg were to meet on the plain. When Zeg reached the acid river, the Emperor blasted away at the rock ledge beneath him. Zeg escaped unscathed and followed the Emperor's trail to the mercury geysers, where he fired on his rival only to hit an inflatable facsimile, the Emperor having deployed a ruse to get Zeg within range of a geyser diverted towards him. Unaffected by the mercury, Zeg pursued the Emperor into the abandoned Dalek workshops. When the Emperor doused Zeg in liquid oxygen from one of the tanks, the cold cut through and caused Zeg to explode. Returning to the city, the victorious Emperor promised the other Daleks that they would improve on Zeg's invention and take to the stars. (COMIC: Duel of the Daleks)

Following several prototypes, the Daleks succeeded in developing interstellar travel and constructed a space fleet. Leading the fleet, the Emperor commanded a Dalek saucer designated Proto-Leader. Via radio, the Emperor warned "all planets in all galaxies" that the Daleks were coming before seeing to the invasion of Alvega, the nearest planet to Skaro. Finding only plant life, the Daleks' audio meter hinted at the presence of intelligent live and so the Emperor had Scout Daleks clear a path through the grass in their search. Soon after, the Daleks found themselves under attack by intelligent plants known as the Amarylls, who were led by a Controller. When the Amarylls turned on the Emperor's fleet, the Emperor fled the planet, leading the main space fleet to other conflicts while entrusting four ships remaining to wipe out all life on Alvega. The Emperor was witness to the successful destruction of Alvega, announcing that whatever the Daleks could not conquer was to be destroyed. He then turned his attention to Solturis, a mineral rich world populated by humanoids. (COMIC: The Amaryll Challenge)

Landing on Solturis, the Emperor claimed to come in peace and gained the trust of the planet's ruler Redlin. Learning that the planet had a defensive weapon, the Penta Ray, the Emperor had a fake created and smuggled into the capital city as the Daleks made off with the real Penta Ray. Upon returning to their ship, however, it was found that the weapon required a missing key to operate it. The Daleks were approached by Geltis, a Solturian traitor who offered the key in exchange for being allowed to rule Solturis. Confident of victory, the Emperor left the planet to attend to other conquests while leaving two Dalek ships behind. Shortly after, the Emperor learnt that the Solturians had reclaimed the Penta Ray, which they used to destroy the Dalek forces. However, his attention was drawn away by a message calling him back to Skaro. (COMIC: The Penta Ray Factor)

The Emperor returned to Skaro, where he found that a radioactive cloud of rust was wreaking havoc upon the Daleks, eating away at their outer casings. Fear of this plague led to Daleks attacking each other while the Emperor determined that it was being carried inadvertently by the Black Dalek Leader. Though the Black Dalek intended to die, the Emperor deemed that his loss would be unacceptable and so had his casing reconstructed while the Daleks worked to cure the plague.

As the Daleks rebuilt from the rust plague, a Monstron spacecraft had landed on Skaro, (COMIC: Plague of Death) and the Emperor watched as Dalek hoverbout patrols fell victim to its defenses. The Monstrons then sent their Engibrain soldiers to attack the Dalek City, entombing it in liquid metal. The Emperor survived, saved from an electric eel by the Daleks' magnetiser. Using the eel's electricity, the Emperor intended to use an underground river to launch a surprise attack only to find the spacecraft had been destroyed. Nevertheless, the Emperor was conscious of threats from space. (COMIC: The Menace of the Monstrons)

A few months later, the Dalek City was rebuilt as the Emperor ordered that a space station be constructed as a base for the mining and exploration of the planet Oric. However, the Emperor found that Skaro Control Sky Seven had been attacked by the Interceptors of the robotic Mechonoids, resulting in the destruction of a Red Dalek Leader. Learning that the Mechonoids made use of hypnotic clouds to enslave Daleks, the Emperor used the thought patterns of an afflicted Dalek to create the image of a Mechonoid. Preparing for galactic war, the Emperor ordered the Daleks to construct new defenses and weapons while searching through space for the potentially useful inventions of other races. (COMIC: Eve of War)

As the Daleks searched space, the Emperor was on Skaro when the hidden planet Phryne was uncovered and conquered by the Daleks led by Searcher One Leader, who ordered it reported to the Emperor. (COMIC: The Archives of Phryne)

The Astrodalek detected the appearance of a new, rogue planet, named Skardal by the Emperor, who ordered it be tracked. Finding that its course had been diverted to Skaro, endangering the Daleks, the Emperor had the Daleader's fleet set out to stop it. Using magnetic meteorites, the Daleks sent Skardal on a course to Mechanus. (COMIC: The Rogue Planet) Skardal was pursued by a Dalek rocket, actually commandeered by an alien agent, which the Emperor ordered detonated only after entering Mechanus' orbit. However, the rocket's warhead was detatched and sent back to Skaro, where it was destroyed by defensive rockets. This resulted in the destruction of Skardal before it could strike Mechanus, thus preventing war between the Daleks and the Mechonoids. (COMIC: Impasse)

When the Terrorkons endangered the underwater rocket defense system, the Emperor ordered against detonating the rockets lest the City be damaged and poison since the Terrorkons themselves were a means of defense. Finding that a Terrorkon had acquired a Dalek rocket, the Emperor went with the Red Dalek through the ancestors' extractor pipes to destroy the Terrorkon. Finding that the rocket had been discarded and inadvertently activated, the Emperor had the Red Dalek disarm it, saving the City. The Daleks themselves were saved from the Terrorkon when it was attacked by an eel, with the Emperor ordering a search to find all potential dangers on Skaro. (COMIC: The Terrorkon Harvest)

During the exploration of Skaro, the Emperor learnt of the existence of preserved Humanoid Daleks when a Dalek admitted to killing one. He then ordered patrols to search for other survivors so that the Daleks may learn the secrets of their ancestors. However, a clash between the two remaining Humanoid Daleks, Lodian and Zet, resulted in both their deaths after their capture, with their secrets lost to the Metal Daleks. (COMIC: Legacy of Yesteryear)

Whilst ordering the construction of a new road on the Lake of Mutations, the Emperor was questioned by a Dalek who did not make themselves known. Placing his subordinates under scrutiny, the Emperor found that a One in a Million Dalek sought to preserve the beauty of flowers, destroying machinery and Daleks themselves to that end. His position as Emperor challenged, the Golden Dalek confronted the One in a Million Dalek and his growing faction. Pointing out that the Dalek had neglected to preserve the dying flowers on his own outer casing, the Emperor saw that he was exterminated, dismissing beauty as a concept for human beings who were to be destroyed. (COMIC: Shadow of Humanity)

When the Jevon spaceship Guardian approached Skaro, the Emperor had the magnetrap bring it down to the planet. Kirid, the Jevon commander, revealed that they were headed to Arides to destroy the plants there before they could pollinate and endanger all life in the universe. Though the Daleks believed themselves immune, they were deceived into believing they were susceptible. When a Dalek was destroyed while examining the Jevon weapon, the Emperor led ships to destroy the Guardian, doing just as it completed its mission on Arides. The Emperor then declared all-out war on humanoids everywhere. (COMIC: The Emissaries of Jevo)

Detecting the approach of the spacecraft Starmaker, the Emperor ordered it bombarded with meteorites, forcing the ship to land on Skaro. His attention was to acquire prisoners to learn the location of their planet. While Starmaker was destroyed by the Daleks, three survivors were able to escape using a stolen Dalek transporter. However, they left behind a sheet of paper revealing the path to their planet, Earth, which the Emperor vowed to conquer. (COMIC: The Road to Conflict)

Aboard his Dalek Flagship, the Emperor led an invasion fleet into the solar system on a course to Earth. Engaging what appeared to be a fleet of organic spacecraft, actually the mediums of the telepathic Elders, the Dalek fleet was overpowered and forced to regroup before attacking a human colony on Titan, moon of Saturn. Capturing six human colonists, the Emperor had them conditioned to operate Dalek spacecraft in order to attack the mysterious aliens. However, the Elders saw through this plan and freed the humans of the influence of the Daleks who, induced to state of confusion, destroyed the majority of their own fleet. Spared the power of the Elders, the humiliated Emperor was forced to retreat. (COMIC: Return of the Elders)

25th century invasion
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)

27th century invasion
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 weaponry, 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 interrogated 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. (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)

The rebuilt Emperor
The Emperor participated in a temporal attempt to invade Earth before it knew what hit it; the Emperor followed the main invasion force in his time machine to 2415. However, his machine was faulty and he instead landed in the middle of the Battle of Agincourt in 1415. While he was lost in time, his forces, clueless as to what to do without their leader, surrendered, aborting the invasion. Sometime later, the invasion of Uranus was likewise a failure for lack of efficient command by the Emperor, whose casing's sonic guard had been damaged by the supersonic waves used by an Earth colony on an artificial satellite orbiting Uranus.

On the Super-Skaro year, in the 40th century, (COMIC: The Brain Tappers ) the Commander of the Red Extra-Galactic Squadron protested when the Black Dalek began to announce that the Emperor was to be re-elected once more. According to the Red Commander, his squadron, during its distant travels, had witness the disastrous effects of the Emperor's strategies against humankind, leading the Red Daleks to rule the Dalek Prime unfit for leadership.

Outraged, the Emperor ordered the entire Red Squadron exterminated at the hands of the Black Dalek. However, this sent the Dalek Prime in an identity crisis which spanned several weeks of reclusion, at the end of which he emerged with the conclusion that the Red Daleks had been right after all, and he was not perfect. However, this did not mean he relinquished power; instead, he allowed the Dalek Scientists to take his casing apart and rebuild it from the ground up, integrating more cybernetics than before. In the meantime, the Daleks were ruled by the Brain Machine, to which the Emperor had transmitted all his knowledge.

When he returned, the fault with the Golden Emperor's memory cells had been found and the entire first half of his casing had been replaced, now containing a large, external, artificial organic main brain in addition to the actual brain of the Dalek mutant, and which was far more powerful than any computer. (COMIC: The Secret of the Emperor)

The Time Destructor
In the year 4000, the Daleks constructed a base on the planet Kembel and formed an alliance with the rulers of the Outer Galaxies to gather the resources they needed to build the Time Destructor which they planned to use to wipe out the entire Solar System. The Dalek Prime awaited the completion of the invasion on Skaro. Due to the interference of the First Doctor, the Time Destructor's taranium core was stolen. The Dalek Prime sent a Red Dalek from Skaro to Kembel in another time machine to aid in its recovery. When the taranium was recovered and returned to Kembel, the Doctor got hold of the Time Destructor and wiped out the Dalek force stationed there. The Dalek Prime, unable to replace the invasion fleet and the Black Dalek commanding it, was forced to accept the defeat. (PROSE: Mission to the Unknown, The Mutation of Time)

Search for the Human Factor
In the wake of the Time Destructor disaster, much of the galaxy was warned about the Dalek plan and several war forces — among them the Thals, the Draconians and the Terran Federation — were formed to battle the Dalek Empire in a series of wars fought over the course of the millennium and into the 5000s. It was eventually predicted by Dalek computers that the race would become extinct within eighty years if it could not secure victory. The Dalek Prime took on the title of the Dalek Emperor during this time and, desperate to win, ordered the Daleks to conduct research into the Dalek Factor. (PROSE: The Evil of the Daleks) He ordered the Daleks to capture the Second Doctor so that they could force him to conduct research into the Human Factor. This would unlock the secrets of the Dalek Factor which was to be spread throughout all areas of human history, giving all humans the mentality of a Dalek and preventing the Great War from ever happening. When the Doctor escaped, the Emperor was caught in the chaos of a civil war between humanised Daleks and un-altered Daleks and nearly destroyed. (TV: The Evil of the Daleks) Having survived, the Emperor's forces began rebuilding, (COMIC: Bringer of Darkness) resulting in the emergence of a new command structure involving grey Dalek drones and Gold Supreme Daleks. (TV: Day of the Daleks)

Shortly after this, the Emperor met Bernice Summerfield as she moved through time, and questioned her on why the Civil War had occurred and why the other Daleks questioned him. She berated the Emperor during their short discussion, mocking him for not even having a gun, and walked away so that she would live, giving "the greatest insult [she] could think to give a Dalek". The Emperor was left screaming after her for her to obey him and that she would be annihilated. (AUDIO: The Lights of Skaro)

Civil War
After Davros was captured by the Daleks on Necros, the Emperor personally attended his trial on Skaro. The Emperor charged Davros with perverting the destiny of the Daleks, while Davros protested that the Emperor had allowed the Daleks to become weak. Though a number of Daleks considered that they could learn from Davros, the Emperor sentenced him to extermination. Before the sentence could be carried out, the Dalek City was struck by an asteroid while the Daleks' systems were incapcitated by a virus. In the ensuing chaos, Davros was escorted by technobots to the Sixth Doctor and Peri Brown, who took him with them in the TARDIS. From the court room, the Emperor presented video evidence of Davros consorting with the Doctor.

To exact revenge on both of them, the Emperor had Dalek Killer Abslom Daak transmated just before he would have died destroying the Death Wheel in orbit of the planet Hell. Using androids as a decoy, the Emperor secretly gave Daak the task of capturing the Doctor, ostensibly to aid humanity's effort against the Daleks. Once Daak and the Star Tigers captured the Seventh Doctor and Bernice Summerfield on Hell, they were transmated to Skaro, where the Emperor revealed himself. Though an attempt at escape was made, the Daleks quickly pacified the humanoids. Under interrogation, the Doctor was forced to reveal to the Emperor that he had taken Davros to Spiridon, while his friends were conditioned to serve the Daleks and used to force the Doctor to assist the Daleks in eliminating him. While the Emperor remained on Skaro, the Doctor and his friends accompanied a Dalek fleet led by the Black Dalek to Spiridon, where they engaged Davros' Daleks in battle. Ultimately, Davros' Daleks prevailed over those loyal to the Emperor, while the Doctor was able to set his allies free.

Naming himself the new Emperor of the Daleks, Davros took the Doctor and his company with him aboard his mothership, which set a course to Skaro. Upon arrival, the mothership transmitted a computer virus to impair the Dalek City's systems before launching an attack, soon reducing it to ruins. Touching down in his assault shuttle, Davros proceeded to confront the Emperor. A brief argument ensued, after which Davros deemed that the Emperor was no longer needed and ordered his extermination. Subjected to the firepower of two of Davros' Daleks, the Emperor was seemingly killed as his casing was blown apart. (COMIC: Emperor of the Daleks!) However, the Dalek Prime, as the Emperor of the Renegades, had regained control of Skaro and used his ability to be active in the world through remotely-controlled decoy casings to fake its destruction. (PROSE: War of the Daleks)

After the Civil War
The Dalek Prime returned following the Imperial-Renegade Dalek Civil War and set about planning to extinguish the remaining support Davros still had within the Dalek Empire. A deal was made with a group of Thals who kidnapped Davros, along with the Eighth Doctor, and they transported him to Skaro to stand trial. Before the trial, the Dalek Prime claimed to the Doctor that much of Dalek history was a fabrication to prevent destruction of Skaro by Davros and the Seventh Doctor at the culmination of the Shoreditch Incident. During Davros's trial, one of Davros's supporters destroyed a decoy of the Dalek Prime, igniting another civil war. The Dalek Prime claimed victory after Davros's capture and apparent execution and, after his supporters were apparently wiped out, proclaimed himself the Dalek Emperor again. (PROSE: War of the Daleks)

According to the research of human historians of the Daleks, however, the Dalek Emperor took over the Imperial Dalek faction after Davros was lost in the explosion of Skaro's second sun (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) caused by his activation of the sabotaged Hand of Omega in 1963. (TV: Remembrance of the Daleks) He carried forward Davros's long-held plan to move against the High Council of the Time Lords, thus beginning the Last Great Time War. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

The Emperor remained on Skaro whilst it sent the Dalek Supreme to take over the Library on Kar-Charrat. After the Seventh Doctor's apparent death before he was able to be interrogated, the Emperor ordered the Dalek Supreme to return to Skaro and self-destruct, replacing him with the Chief Scientist. With the library destroyed, the Emperor declared that he would devise an alternative plan. (AUDIO: The Genocide Machine)

Second Great Dalek Occupation
Upon learning of Project Infinity, the Emperor planned to hijack it to bring a victorious Dalek army to N-Space from a parallel universe. He had Vega VI invaded and the people begin mining veganite, disguising his ambitions by invading the rest of Mutter's Spiral. (AUDIO: Project Infinity) He monitored the conversations between the Dalek Supreme and Susan Mendes, planning on utilising her to improve the efforts of the workforce. (AUDIO: Invasion of the Daleks)

The Emperor made sure that Suz would not be exterminated except on his own order, although he was aware that her unique position might compel her to act against the Daleks. (AUDIO: The Human Factor) He allowed Suz and Kalendorf to be made aware of his and the Dalek Supreme's suspicions, knowing that it would motivate them to redouble their efforts to prove their loyalty. (AUDIO: "Death to the Daleks!")

With the veganite on board, the Emperor headed to the Lopra system before Suz's rebellion. He was almost killed when Kalendorf and the Seer of Yaldos linked minds with Mirana and struck back at him, giving Kalendorf a brief look into his mind. The Emperor recovered and took control of Project Infinity, finding a suitable universe and bringing through the alternate Daleks who attacked upon learning of the Emperor's Daleks many crimes. (AUDIO: Project Infinity)

Within Susan Mendes
In the first battle on Lopra Minor, the Emperor was captured by the Earth Alliance and became totally inert, transferring his consciousness into Suz (AUDIO: Dalek War: Chapter One) as he knew that Alby Brook would save her. (AUDIO: Dalek War: Chapter Three) His body was taken by the Mentor to a secure location (AUDIO: Dalek War: Chapter One) whilst his Daleks took possession of his casing.

The Daleks took Suz and scanned her, briefly reawakening the Emperor. (AUDIO: Dalek War: Chapter Two) They completely wiped Suz's personality, giving the Emperor complete control, and he tortured Kalendorf to learn of his plans, focusing all of the Daleks' mental energy into him. Kalendorf was able to restore Suz momentarily with his telepathic powers, allowing her to cause the Great Catastrophe and kill the Emperor. (AUDIO: Dalek War: Chapter Four)

The Last Great Time War
During the early part of the Time War, the Emperor was informed by the Dalek Time Strategist about Project Revenant. Romana II tried to convince him to stop the war as it would involve both sides being destroyed as a result. (AUDIO: Desperate Measures) Because of 's activation of the Heavenly Paradigm, the Emperor took control of the Cruciform. (TV: The Sound of Drums; AUDIO: The Heavenly Paradigm)

After the Valeyard temporarily succeeded in wiping out all Daleks in N-Space save for the Dalek Time Strategist, (AUDIO: The War Valeyard) the Strategist used dimensional engineering to restore the Empire. However, believing the Daleks needed "a god" rather than "a relic" to lead them, the Strategist discarded the substitute Davros he had created as an unsatisfying leader for the Dalek race. Instead, he "scoured every dimension", looking for the original Emperor. Although initially unsuccessful, he was eventually able to resurrect the Emperor using the temporal power of the multiverse itself.

The Emperor began to make himself heard as he was coalescing, roaring "I AM RETURNING!". The process accelerated past this point until the Emperor had materialised completely, descending over the planet Koska inside his shift and making a broadcast during which he announced his "resurrection" to the universe. (AUDIO: Restoration of the Daleks)

The Dalek Emperor resided in his throne room within the Dalek City on Skaro, protected by the Imperial Guard Daleks. The Daleks' strategy computers and assessment engines predicted an incoming war, that would rage throughout all time and space, against an "ancient enemy" that was potentially a match for the Daleks. Believing that the coming conflict would take every resource and stratagem just to survive, the Emperor sought to ensure victory by employing new methods, daring to even question what it was to be a Dalek. As such, the Emperor gave an order with his unique ident codes to summon four high-ranking bronze Daleks, all of whom were deemed to have demonstrated abilities above and beyond the simple execution of orders as they used initiative to emerge successful in every endeavour, to meet with him: the Commandant of Station Alpha, an Attack Squad Leader in the Thirtieth Assault Group, the Force Leader of the Outer Rim Defensive Batallion and lastly the Dalek Commander of the Seventh Incursion Squad, whose order came just after he had saw to the extermination of the Mechonoids.

Explaining their new purpose as a weapon, the Emperor announced that that they were to be reconditioned to enable them to think as no Dalek had ever been able to think, to think and become like the enemy, daring to plan and act in ways that no other Dalek, even himself, would countenance. Designating them as the Cult of Skaro, the Emperor chose to name the four Daleks Thay, Caan, Jast and Sec, the latter being the leader of the Cult. On the Emperor's order, the Cult were escorted to the Weapons Factory to be fitted with the latest armour and weaponry, while a unique black casing composed of Metalert was prepared for Dalek Sec. (PROSE: Birth of a Legend)

Towards the end of the War, the Emperor oversaw the creation of the Eternity Circle, and was present when they created the Temporal Cannon to use against the Time Lords. The Emperor witnessed the other temporal weapons used against human prisoners, like the former governor to Moldox, Jocelyn Harris who had betrayed her people to work for the Daleks as their puppet. The Emperor watched as Jocelyn was removed from history as a demonstration. (PROSE: Engines of War) When Skaro was devastated, the Emperor was thought to have been killed. (GAME: City of the Daleks)

The Dalek Emperor was aboard his saucer flagship when all thirteen incarnations of the Doctor moved Gallifrey to a pocket universe on the last day of the Time War. The assembled Dalek Fleet ended up firing on itself through the space Gallifrey once occupied, an event which was presumed to have been the activation of the Moment; (TV: The Day of the Doctor) as such, the Emperor was believed to have died with the rest of his species. (TV: The Parting of the Ways)

After the Time War
The Emperor's lone ship barely survived the Time War, falling through time in a heavily damaged state. The nine-metre tall Emperor's new casing had the appearance of his Kaled mutant revealed floating in a transparent tank of liquid, topped by a giant-sized Dalek dome, complete with eyestalk, flanked by panels of armour dotted by Dalek "bumps" with a ring-shaped "throne" on the bottom. He went into seclusion at the edge of the solar system "damaged but rebuilding" during the Fourth Great and Bountiful Human Empire while he used any humans that stumbled upon him to create a new army of Daleks, and he steadily rebuilt his fleet.

Circa 199,909, he secretly installed the Jagrafess aboard Satellite Five to play the "long game" of slowly manipulating humans and re-establishing the Dalek species and fleet. A hundred years after the Jagrafess was killed, in the year 200,100, the Emperor was still using Satellite Five, now renamed the "Game Station" to manipulate humanity and conceal a Dalek fleet. (TV: Bad Wolf) The Emperor secretly used transmat technology aboard the space station to kidnap humans for nearly two hundred years. The kidnapped humans were harvested for their genetic material, and "one cell in a billion" was used to rebuild a new race of Daleks (TV: The Parting of the Ways) numbering roughly half a million aboard a fleet of 200 ships in just a century. (TV: Bad Wolf)

Because the Emperor had recreated the Dalek race, he saw himself as a god and immortal and so was worshipped by the new Daleks. These and other religious concepts such as blasphemy were new to Dalek psychology. The Emperor had become insane due to the fact he had been in hiding for so many centuries. (TV: The Parting of the Ways)

The Emperor's pawn aboard Satellite Five, the Controller, hated her masters and transmatted the Ninth Doctor aboard the Game Station to help defeat them. (TV: Bad Wolf) When he encountered the Emperor and his new religiously fanatical Daleks, the Doctor surmised that they were driven insane both because they had isolated themselves for so long, but also because they were in denial of the fact that they were part human. The Daleks killed almost everyone aboard Satellite Five, and they attacked Earth, bombing millions of people, to transform it into the Emperor's "temple". Shortly afterwards, the Doctor turned down his chance to use an uncalibrated delta wave to destroy all nearby life, human and Dalek alike. The Emperor thought he was victorious, but he and his entire fleet were atomised by Rose Tyler after she had absorbed the energies of the time vortex and became the Bad Wolf temporal paradox; (TV: The Parting of the Ways) she later described what she did as "pouring the Time Vortex into his head and turning him into dust". (TV: Doomsday)

The Kotturuh crisis
Sometime after the Last Great Time War, the Tenth Doctor encountered a version of the Dalek Empire who had no recollection of participating in the War. He referred to the event as a "paradox" which had "brought back" the Golden Emperor. (COMIC: Defender of the Daleks) Realising the timeline was "diverging", the Emperor ordered that the situation be rectified and appointed the Time Squad to travel back to the Dark Times and do what they could to ensure the fluctuations in time worked out to the Daleks' advantage. (PROSE: The Guide to the Dark Times)

The resurrected Dalek Empire soon faced attack from the Hond, an omnicidal species from the Dark Times who had been believed to be extinct. The Emperor ordered a squadron of Silver Daleks to track down the Doctor and bring him to Skaro, where the Emperor explained the basics of the situation to the Doctor and commanded him to save the Daleks, which the Doctor reluctantly accepted. The Emperor then sent the Dalek Prime Strategist to apprise the Doctor of the state of Skaro's defences, with the two taking a tour of the Dalek City before heading into the Vault of Obscenities. (COMIC: Defender of the Daleks)

Mutant Phase fiasco
In an alternate timeline where the Daleks came under attack by the infection called the Mutant Phase, the Dalek Emperor still commanded the empire from Skaro, with the Fifth Doctor commenting that they'd both "had a face-lift" since they last met. As the Mutant Phase swarm destroyed Skaro, the Emperor was able to place his mind into the body of the Thal Ganatus, possessing him, and ordering the Doctor to take him back to the 22nd century Dalek invasion of Earth, where the Mutant Phase started. Travelling back in time, the Emperor tried to warn the Daleks of the great catastrophe that would devastate their race, but the Doctor explained that his interference is what caused the mutation in the first place. When the Emperor realised this, he chose not to change the past, erasing both himself and the Mutant Phase from existence. (AUDIO: The Mutant Phase)

The Master once called the Dalek Prime "ridiculous". (PROSE: Legacy of the Daleks)

Another Dalek Prime
According to another account, the battle of Pejorica, fought between the Daleks and the Jariden, occurred at a point in Dalek history prior to the creation of a Dalek Prime encountered by the Doctor in command of a ship. Travelling back in time, this Dalek Prime was able to take control of the earlier versions of the Daleks fighting in the battle; they didn't know about his existence and rank. This account referred to Dalek Primes as an advanced form and rank of Dalek, rather than a singular individual. The time-travelling Dalek Prime, pulled through the Doctor's timestream and encountering the fifth, sixth, seventh and eighth incarnations of the Doctor, was finally trapped in a time loop created by the Fifth Doctor. (AUDIO: The Four Doctors)

Personality
The Daleks believed that the Emperor had the greatest mind in the universe. (AUDIO: Project Infinity)

Characteristics
As the Golden Emperor, he was slightly shorter than the other Daleks, with a disproportionately large spheroid head section rendered in gold rather than grey. He also had three sense globes on each panel of its base unit unlike other Daleks. (COMIC: Invasion of the Daleks) During the war with the Hond, the Golden Emperor was now wearing a battle armour with a significantly smaller globe-like "dome" and had two large white Luminosity discharger instead of a wreath of red ones. (COMIC: Defender of the Daleks)

Behind the scenes

 * The Dalek Prime's original appearance was to be the War of the Daleks TV serial proposed by John Peel. The story was never produced following the show's cancellation in 1989. Peel kept the idea and the Dalek Prime appeared or was mentioned in all of his Dalek novels and novelisations apart from The Power of the Daleks. The audio story The Four Doctors marks the Dalek Prime's only appearance in a story that was neither a novel nor written by Peel (excluding Genesis of the Daleks since it was originally a standard Dalek before future writers came up with the concept of a Dalek Prime).
 * Novels usually refer to the Dalek Prime as a "he" rather than an "it" like all the other standard Daleks. This would also happen with Dalek X in the novel Prisoner of the Daleks.
 * In the non-narrative book The Dalek Handbook, it is said that the Emperor actually survived the Great Civil War despite his apparent demise in The Evil of the Daleks, subsequently refocusing his strategies on time manipulation. This suggests that he and any number of chronologically-later Emperors are actually one and the same.
 * The Golden Emperor features in the Dalek annuals of the late 1970s, mostly in the form of reprinted Dalek Chronicles and games. However, he does not appear in any of the original stories, the majority of which concern the Daleks' conflict with Earth's Anti-Dalek Force in an undisclosed time.
 * The Golden Emperor also appears in Deadline to Doomsday, a Doctor Who Magazine back-up comic and follow-up to Return of the Elders which was under production with Ron Turner, the artist of the original TV Century 21's The Dalek Chronicles, when the artist passed away. The first two pages, with no text or header art, was printed in the end of Doctor Who Magazine 276 among an article remembering Turner. Years later, the comic was completed and printed in the fan magazine Vworp Vworp! 's third issue.
 * Depending on the player's progress, "Dalek Prime" is a potential rank for the Metaltron to attain in the video game NOTVALID: The Last Dalek.
 * A Dalek Emperor of identical appearance, and also voiced by Nicholas Briggs with the same voice effect, appeared in the video game LEGO Dimensions, though it is not clarified whether he is the same Emperor from The Parting of the Ways, or another lookalike using an identical casing as the one from City of the Daleks. However, the game, due to its branching story, is not considered valid on the Tardis Data Core.
