Robot Yeti Robot Yeti were servitors created by the Great Intelligence , originally as protectors before using them as an army . Appearance and construction . The Yeti robots were large and hairy to disguise themselves in the Himalayas . Their claws , feet , and eyes were the only parts not covered in fur ; their claws and feet were black and bumpy , their teeth yellow , and their eyes green . The first Yeti were bigger and more bear - like , whereas the " Mark II " s , as the Second Doctor called them , in London had better - defined hands capable of wielding web - gun s . These Yeti had flaps at their chest which hid the control sphere s that provided their motive power , serving as a brain . Yeti could also be directed somewhere through the use of a locus . Until activated , Yeti could stand immobile for long periods , completely shut down and unaware of what went on around it . When instructions did arrive , it would come to life and begin moving . ( TV : " The Abominable Snowmen " , " The Web of Fear " ) New World University ' s research into nanotechnology and atomic engineering produced Yeti that resembled the " Mark I " models . A control sphere could plunge itself into a human chest , nano - instructions inducing immediate atomic restructuring and multiplication until the person became a Yeti . Whether this meant they were organic or cyborgs is unclear , but these Yeti had yellow fangs and were more susceptable to projectile fire . They could also fire web from their claws . ( PROSE : " Downtime " ) Yeti created by the Intelligence at the end of its life ( called " Mark III " Yeti by Humans as the Intelligence had travelled back in time to before the events where it had created the New World Yeti ) were different from previous versions . They had longer claws and were much larger than previous incarnations ; allowing for them to grab human beings by the throat with one hand . They did not operate by the metal spheres as before , as to remove an obvious design flaw which could be utilised by the humans . These Yeti could continue to operate after their fur outlining had been destroyed , and were impervious to bombs . ( PROSE : " The Forgotten Son " ) History . Origins . The Yeti were created to serve the Great Intelligence ( TV : " The Abominable Snowmen " ) A non - corporeal entity , the Great Intelligence took over the body of Padmasambhava , the lama of Det - Sen Monastery , and built the Yeti over hundreds of years . The Yeti were initially a ruse to scare off curiosity seekers from the mountain cave where the Intelligence planned to manifest ; later , they became more of an army serving the Great Intelligence . These robots were similar in appearance to what explorer Professor Edward Travers called " real " Yeti . ( TV : " The Abominable Snowmen " ) The Intelligence also took over the body of Jemba - Wa , using him to build the yeti . The first individual to be built was a white - furred robot named Kabadom . ( PROSE : " Times Squared " ) 20th century . The Second Doctor , a friend of Padmasambhava ' s , arrived in the Himalayas in 1935 with his companion s Victoria and Jamie . Along with Professor Travers , they put an end to the Great Intelligence ' s plan when Jamie smashed the pyramid control in the cave . ( TV : " The Abominable Snowmen " ) More than forty years later , a formerly non - functioning robot Yeti on display in Julius Silverstein ' s private museum in London was reactivated by a control sphere Travers had re - activated , subsequently somehow transforming into the " Mark II " and killing owner Julius Silverstein . Setting up a Yeti production plant in Wimbledon , ( PROSE : " Millennial Rites " ) the robots then covered London in webbing , forcing the evacuation of the populace . Later , in the Underground , Alistair Gordon Lethbridge - Stewart and his troops attempted to stop them and the Intelligence from using the Underground as a nervous system . ( TV : " The Web of Fear " ) Within days after this was stopped , a returning Great Intelligence reactivated the Yeti and laid siege to Bledoe , Cornwall as part of the second attack . Both British soldiers and Bledoe citizens organised by Lethbridge - Stewart struggled to damage the robots . { PROSE : " The Forgotten Son " ) These twin events gave impetus to the formation of both the Home - Army Fifth Operational Corps and later UNIT . ( TV : " The Invasion " , PROSE : " The Forgotten Son " ) In October of the same year , the Intelligence used the Yeti to launch an attack on the Brigadier in New York City . With the help of Adrienne Kramer , Owain Vine , Edward Travers , and Sally Wright , the Intelligence was defeated and the yeti deactivated . These yeti had the additional ability to harbour the diseased rats which spread the Intelligence ' s plague . ( PROSE : " Times Squared " ) Lethbridge - Stewart again encountered a Yeti on Gallifrey , left over from Rassilon ' s games . On this occasion , the Second Doctor maddened it with a Galactic Glitter , and the resulting rock fall prevented any further interaction with it . ( TV : " The Five Doctors " ) Establishing New World University by 1995 , the Intelligence - controlled Victoria Waterfield utilised control spheres to find the final locus , which bound the Intelligence to Earth . These spheres turned several New World students into Yeti , which proceeded to battle UNIT to defend the generators powering the Intelligence , but were subseqently defeated once more through the combined efforts of Victoria , Sarah Jane Smith , and Lethbridge - Stewart . ( HOMEVID : " Downtime " ) 21st century . A Yeti sidearm was removed from the Hub , the underground HQ of Torchwood 3 , following the Hub ' s destruction . It was then delivered to the CIA Special Operations Division who went rogue and stole the shipment . ( PROSE : " The Men Who Sold the World " ) In 2010 , UNIT Underbase contained a Yeti salvaged from a past alien invasion of Earth . ( COMIC : " The Age of Ice " ) Other encounters . A group of Yetis were put in the Doctor ' s TARDIS by to battle the Graak . ( GAME : " Destiny of the Doctors " ) At some point , explorers searching for the Yeti were captured by the Intelligence . A lama Gampo called the real Yeti to battle against the robots , defeating them . ( COMIC : " Yonder . . . The Yeti " ) The Seventh Doctor figured out he was dreaming when a Yeti asked him for cigarette s in halting Old High Gallifreyan . ( PROSE : " The Hollow Men " ) New Jupiter ' s EarthWorld themepark had replica Yeti as part of the Twentieth - Century London Zone attraction . Fitz Kreiner , who came from the early 1960s , didn ' t know why " abominable snowmen " were meant to be part of Swinging London . ( PROSE : " EarthWorld " ) A robotic yeti attended Bonjaxx ' s birthday party at Maruthea . It drank a martini while some of the party - goers fought . ( COMIC : " Party Animals " ) Alternative timelines . In an alternate timeline created by the Black Guardian where the First Doctor never left Gallifrey , and became Lord President , the Yetis were one of many forces that invaded Earth , and fought over the planet with invaders of various alien races . This timeline was destroyed when the Seventh Doctor retrieved the Key to Time . ( COMIC : " Time & Time Again " ) In the pocket universe of the Great Kingdom , a trapped Intelligence used sheer will to transform the material around it into eight - foot - tall Yeti with red - brown fur animated directly by the Intelligence . ( PROSE : " Millennial Rites " ) In an alternate dimension in which the Doctor ' s adventures existed as a fictional TV show called " Doctor Who " , a fan dressed as a Robot Yeti was present at a " Doctor Who " convention which the Eleventh Doctor visited with Ally in 2013 . ( COMIC : " The Girl Who Loved Doctor Who " ) Minor references . " Abominable snowmen " were filed in the Fourth Doctor ' s memory files . ( COMIC : " Doctor Who and the Iron Legion " ) Behind the scenes . Appearances in unmade stories . The Yeti would have reappeared in " The Laird of McCrimmon " , a story abandoned because of the Yetis ' creators dispute with the BBC . This story would have seen the writing out of the character of Jamie McCrimmon . The Yeti would also have also appeared briefly in the planned 30th anniversary special " The Dark Dimension " as one of the races controlled by Hawkspur .
