Axos Axos was a composite creature , a scavenger entity which came to Earth , supposedly for fuel . Its real motivations were to drain all energy from Earth , with an ultimate plan to gain the secret of time travel , allowing it to feast anywhere in space and time . After its defeat , Axos returned to attack Earth twice . Biology . Axos was grown from a single cell and had nutrition and energy cycles that needed to be replenished . The eye of Axos was on a stalk that could move , the pupil lighting up when it communicated with its other parts and displaying information . The inside of Axos was covered in claws which could restrain prisoners and could fire long tendrils to drag victims within . It was a biological creature / spaceship ; " Axonite " and the " Axons " were extensions of it and were independent , though all of Axos was telepathic and each element could feel what the other did . ( TV : " The Claws of Axos " ) It used thought windows to see the different sections of itself and would bleed if cut into . As Axos absorbed energy directly , individuals walking within it would give it more power the faster they moved . ( AUDIO : " The Feast of Axos " ) By its nature , Axos was morphologically unstable living organic matter , which meant it was possibly capable of performing Block Transfer Computation s and survivng the stress . ( PROSE : " " ) Axonite . The " chameleon " of the elements , Axonite was a " thinking molecule " in which each molecule was individual , so to speak . It used the energy it absorbed not only to copy but to recreate and restructure any given substance . A lasonic injection of Axonite could enlarge and shrink organisms . It could absorb , convert , transmit , and program all forms of energy ( TV : " The Claws of Axos " ) as long as the energy " exists " . ( PROSE : " Doctor Who and the Claws of Axos " ) Additionally , individuals could be copied to obtain their knowledge , but some objects were too complex to be copied . ( AUDIO : " The Feast of Axos " ) Axons / Axonoids . Axons appeared as golden humanoids with white bodies covered in gold blotches . Their skin was metallic gold , with curly hair and " covered " eyes . They could transform into monsters . They could lash out with their tentacles to either shock or disintegrate enemies . They could also instantly absorb victims . ( TV : " The Claws of Axos " ) The Sixth Doctor called these transformed creatures " Axonoids " while Axos referred to them as " Axos units . " ( AUDIO : " The Feast of Axos " ) Biotechnology . The Axons described their technology as having taken a more organic route , and claimed Axonite to be the source of all their growth technology . Axos also possessed some power of time travel , being able to make time jump s that could only travel moments into the past . ( TV : " The Claws of Axos " ) It could incorporate alien technology into itself ( though some was not compatible ) and improved the technology with Axonite . ( AUDIO : " The Feast of Axos " ) History . The Axos worlds were on the edge of the Mutter ' s Spiral . At some point by the 20th century , they were crippled by extreme solar flare activity and entropised , being drained of all life and energy . ( PROSE : " Doctor Who and the Claws of Axos " ) Axos was the last remnant of their culture and was grown for the escape journey . It was a scavenger , sucking energy from planets . Axos encountered and captured his TARDIS , keeping him prisoner as he directed them to Earth , expecting to get back his craft . In England . On Earth , they tried to start a " feeding cycle " . They met with UNIT and promised them axonite to enlarge food and end world hunger . UNIT ordered worldwide distribution . The Third Doctor realised the Axons planned to drain the planet of all its energy . They took power from a nuclear power plant and later raided the plant , killing members of UNIT . They cloned Bill Filer for information but the real Bill escaped , preventing this . The Doctor stopped them by placing Axos in a time loop . ( TV : " The Claws of Axos " ) Some of the axonite was kept ; the Forge had a sample of Axonite in the archive room of their Alpha Facility . ( AUDIO : " Project : Lazarus " ) In Japan . A fragment of Axos was freed from the time loop by Chiyoko to ensure her creation , ( COMIC : " The Child of Time " ) and infiltrated 21st century Japan . Disguising themselves as humans , the Axons produced a television programme for children promoting a new soft drink , Goruda . When children drank it , they developed telepathy and were transformed into Axons . Using the children as leverage , Axos convinced the mayor of Tokyo to send it power from a nearby nuclear plant , claiming they only needed enough power to leave . Instead , Axos used the energy to transform into a giant monster , aiming to begin a new feeding cycle . The Eleventh Doctor defeated Axos by having the citizens of Tokyo turn on all of their electrical appliances , drawing the plant ' s energies away from Axos , starving and eventually killing it . ( COMIC : " The Golden Ones " ) Beyond the 21st century . In the mid - 21st century , British explorers tried to break into the time loop Axos was imprisoned in , hoping to use Axos ' power for a new age of energy for the Earth . Axos turned their transmitter into a receiver and began feeding on Devesham . It copied the Sixth Doctor and made him dematerialise the TARDIS out of the time loop as Axos would follow . Two of the explorers set off a nuclear explosion with their ship , dying for nothing , before the Doctor used the fast return switch to send Axos back . Separated from its main body , the Axon copy of the Doctor melted ; Axos would remain trapped in and feeding on the explosion until the time loop decayed naturally , sometime six billion years in the future . ( AUDIO : " The Feast of Axos " ) Other appearances . At some point , the Eighth Doctor and Mary Shelley fought the Axons . ( AUDIO : " Mary ' s Story " ) An Axon was held in Dauntless Prison . ( TV : " Liberation " ) 78351 was a mutant with Axon , Ogron , and Pyrovile gene s . ( PROSE : " Lights Out " ) Minor references . Axos was filed in the Fourth Doctor ' s memory files .
