Kaled mutant Kaled mutants were the mutated descendants of the humanoid Kaled s on the planet Skaro . Enclosed in protective armour and weaponry , they became the organic parts of the Dalek s , mounted in the upper parts of the Dalek travel machines . The Third Doctor once described the Kaled mutant to Sarah Jane Smith as " a living , blubbling lump of hate " . ( TV : " Death to the Daleks " ) Biology . Kaled mutants had a fundamental DNA type of 467 - 989 . ( TV : " Daleks in Manhattan " ) They were cephalopod , being large brained creatures with tentacle s , though young mutants were globular , soft and shapeless with tendrils . Although usually dependent on their travel machines for offence / defence , the bare mutant could be dangerous ; even the young were quite lethal and capable of strangulation with their tentacles , and , in this way , attacked the fourth and seventh incarnations of the Doctor . ( TV : " Genesis of the Daleks " , " Remembrance of the Daleks " ) The Fifth Doctor once said that they had a deadly sting , and during a 1984 incursion into London , one of these creatures , separated from its casing , attacked and injured a human soldier without difficulty . ( TV : " Resurrection of the Daleks " ) One Dalek remained operational for four thousand centuries . ( AUDIO : " The Lights of Skaro " ) The mutants on occasion demonstrated an accelerated healing ability in response to localised wounds . One Dalek mutant in particular , while being tortured by Commander Farrow , began to repair its damaged body , its flesh growing over Farrow ' s hand and burning it . ( AUDIO : " Jubilee " ) The voice of a Dalek was electronic as the actual vocalisations from the mutants amount to little more than squeaking sounds . Without the assistance of their casing , they were unable to produce speech as they did not possess tongues or vocal chords . ( TV : " Resurrection of the Daleks " , AUDIO : " Jubilee " ) Kaled mutants were quite possibly fatal to a Time Lord when eaten . ( PROSE : " The Scarlet Empress " ) However , their " Dalek juice " could be ingested with no apparent ill - effect . ( AUDIO : " Jubilee " ) The Eleventh Doctor claimed that " [ t ] here [ wasn ' t ] a bone in [ a Dalek ' s ] body . " ( TV : " Victory of the Daleks " ) Variations . Kaled mutants often varied in appearance , as the Daleks continuously altered their DNA , ( TV : " Victory of the Daleks " ) though kept the same basic structure of a relatively - octopoid species with a comparatively large brain . Because the mutants were genetically designed to " not die , " as they aged they would degenerate and liquefy . ( TV : " The Witch ' s Familiar " ) Davros ' s original mutants were yellowish - green globs with tendrils able to lash out and choke someone . ( TV : " Genesis of the Daleks " ) Thousands of years later , there were mutants in the Skarosian wilds . These appeared as gurgling pink blobs that could stretch and be handled , but had no apparent tentacles , brain , or eyes . Whatever reason they were not in Dalek casings is unknown . ( TV : " Destiny of the Daleks " ) Other mutant variations included one that possessed a clawed " hand " , during a time when the Thal s believed the Daleks ' mutation had not come " full - circle " and that they had not reached their final form . ( TV : " The Daleks " ) Other mutations were green blobs with tendrils that were " scooped " into their casings . ( TV : " The Power of the Daleks " , " The Evil of the Daleks " ) During the Imperial - Renegade Dalek Civil War , the mutants were eyeless and green with whip - like tentacles . ( TV : " The Five Doctors " , " Resurrection of the Daleks " ) The Imperial Dalek s commanded by Davros were surgically altered , with their appendages physically grafted into their machines , which the Renegade Dalek s saw as impure . ( TV : " Remembrance of the Daleks " ) Others , after the Last Great Time War , were pale - pink , blue - green or green - brown with one large functioning eyeball and a small vestigial socket . The remnants of a face could be seen , more clearly on some mutants than on others ; as well as the functioning eye and the sealed - up eye , a nose and mouth were vaguely discernible . ( TV : " Dalek " , " The Parting of the Ways " ) The mutants created using human cells produced small , blue - green creatures , apparently consisting purely of a head , with two eyes and an overall clearer " face " . ( TV : " The Parting of the Ways " ) Dalek Sec had lower tentacles that were long enough to grab hold of an adult human and had an unusual , trunk - like appendage that could envelop and carry a whole adult human . ( TV : " Daleks in Manhattan " ) Mutants of the New Dalek Empire were grown by the cells of Davros ' own body , ( TV : " The Stolen Earth " ) meaning they were not " pure " Daleks . Survivors of the encounter with the Doctor , using a progenitor , tricked the Eleventh Doctor into helping create a New Dalek Paradigm , possessing pure DNA but still maintaining the appearance of other post - Time War mutants . ( TV : " Victory of the Daleks " , " Asylum of the Daleks " , " Into the Dalek " COMIC : " The Only Good Dalek " , GAME : " City of the Daleks " , " The Doctor and the Dalek " ) History . " For an account of the creation of the Daleks , see separate article . " Kaled mutants appeared different over time , and , as noted above , during the war between the Imperial and Renegade Dalek factions , the two sides had physical differences , with Davros ' side now altered into true cyborg s and physically made one with their travel machines , ( TV : " Remembrance of the Daleks " ) whereas they had only used the casings as battle armour and were not actually integrated into them . ( AUDIO : " The Four Doctors " ) Iris Wildthyme once became fatally ill after eating a live Kaled mutant . ( PROSE : " The Scarlet Empress " ) . By the time several Dalek variants from across history had returned to Skaro to make it anew , the Dalek City possessed " living " sewers where the walls were made of decaying , liquefying , enraged mutants that would even attack other Daleks if they could .
