Humanised Dalek Humanised Daleks were , as the name suggests , Dalek s implanted with the Human Factor as isolated by the Second Doctor . The Factor caused significant changes in the behaviour of the creatures , which led to an enormously destructive Dalek Civil War which for a time put the future of the species in doubt . Nature . The original humanised Daleks received the Factor from positronic brain s constructed by the Doctor . The nature of the relationship between this machine intelligence and the organic brain of the Dalek creature is unclear . Later , mass - implantation of the human Factor was contrived by the Doctor , suggesting it was possible to directly alter the nature of a Dalek without the use of technology such as the brains . ( TV : " The Evil of the Daleks " ) Large numbers of humanised Daleks were seen in their colony on Kyrol . ( COMIC : " Children of the Revolution " ) Humanised Daleks behaved fundamentally differently to the rest of the species : they were non - conformist , sometimes playful , frequently questioned orders , and lacked instinctive obedience to their superiors . Perhaps most unusually , they showed no signs of the intrinsic Dalek desire to destroy all other life - forms , or the self - destructive psychosis which tended to afflict Daleks who acquired physical or behavioural traits from other species . It was suggested that it was this which allowed them to realise their full psychokinetic potential . ( TV : " The Evil of the Daleks " ) Origins and history . The discovery of the Human Factor . As part of a typically devious scheme , the Daleks recruited the Doctor to discover those traits which epitomised the essence of the human s who had so often defeated them . The Doctor was told that the Daleks planned to assimilate this " Human Factor " into themselves , but in fact the plan was to use it to define the quintessential Dalek Factor and introduce this into the human race instead and prevent the Great War from happening . ( PROSE : " The Evil of the Daleks " ) The Doctor successfully determined the nature of the human Factor and implanted it into three test Daleks known as Alpha , Beta , and Omega . These original humanised Daleks were later reintegrated into the population on Skaro . Inevitably , one of them questioned a routine order given by a superior . Civil war . The Dalek Emperor realised that independent thought was anathema to Dalek culture and civilisation and that the humanised Daleks were a deadly threat . It ordered that all Daleks be re - implanted with the Dalek Factor - but the conversion system had been sabotaged by the Doctor , and rather than reinforcing the Dalek Factor , many Daleks were exposed to the human Factor instead . Led by Alpha , Beta , and Omega , the humanised Daleks approached the Emperor , demanding to know the reasons for the orders with which they were constantly being issued . Fighting broke out between them and non - Humanised Daleks , which rapidly escalated into a full - scale war throughout the Dalek City . Even the Doctor , who was largely responsible for the conflict , believed the fighting would only end with the final destruction of the Dalek race . ( TV : " The Evil of the Daleks " ) Azhra Korr , and the final sacrifice . However , the unmodified Daleks were too numerous and the surviving humanised rebels , led by Alpha , were forced to flee Skaro in a captured saucer . Alpha had a vision of a world where they could live in peace and seclusion , knowing the rest of their species would never stop hunting them . They settled on Kyrol in a subterranean city , Azhra Korr , beneath the sea bed . Here they created their own culture , making art , meditating , and developing the psychic abilities latent in all Daleks . Many years later a human submarine was disabled by a mysterious electromagnetic pulse and the Daleks intervened to save them . They were delighted to learn the Doctor was also aboard , as they considered him their saviour . However , their need to remain secluded meant that neither the humans or the Doctor could ever leave the city again , and Alpha extracted a promise to this end from the Doctor . However , the saviour of the Daleks broke his word and attempted to contact the humans on the surface of the planet . At the same time paranoia and distrust was spreading amongst both the humans and the humanised Daleks . The Doctor eventually discovered that the Daleks had been duped by Kata - Phobus , the last native Kyrolian , an immensely powerful psychic creature . Kata - Phobus had sent Alpha the vision of Kyrol , luring the Daleks here so they could prosper and multiply — before harvesting them for their vast reserves of psychokinetic energy and going on to destroy the human colony as well . Alpha and the other Daleks refused to let themselves be used this way , opting to self - destruct " en masse " — the interruption in Kata - Phobus ' feeding cycle killing the Kyrollian , even though it meant the sacrifice of every known humanised Dalek . ( COMIC : " Children of the Revolution " ) Similar examples after the Time War . Similar phenomena occurred with Daleks " after " the Last Great Time War , but on account of different circumstances . In one instance , one Dalek drone ( nicknamed Metaltron by its captor , Henry van Statten ) experienced a flood of human emotion s after extracting DNA from Rose Tyler . This drone eventually considered emotions to be unbearable " sickness " , and asked for the order to commit suicide . ( TV : " Dalek " ) Later , the leader of the Cult of Skaro , Dalek Sec , engulfed the human Mr Diagoras and underwent a " Final Experiment " . He became an entirely new creature , a Human - Dalek , who felt all the emotions of humans . A force of " Dalek - humans " ( human shells with Dalek minds but with a bit of Time Lord DNA that gave them free will ) was also created . However , Sec and the " Dalek - humans " ended up questioning their species ' xenophobia and ruthlessness ; the hybrids were exterminated by the last remaining pure - bred Dalek in existence , Dalek Caan .
