GENIE A GENIE , short for Genetically Engineered Neural Imagination Engine , was a small , man - made creature with the power to grant its owner ' s wishes . The prototype was first created in 2375 by Salvatorio Moretti of the Bureau Tygon . A GENIE was a small scaly creature that looked much like a dragon , but had the bill of a duck - billed platypus . They had advanced AI and could easily figure out how to tap into any available power source to grant bigger and bigger wishes , to the point where they almost had no limit . In a potential timeline seen by the Tenth Doctor , the GENIE was specifically created to easily provide everything the 24th century society pleased . However , what was intended as a simple and innocent invention quickly got out of hand . Their inventors failed to realise how powerful they truly were . Because of this , and the GENIE ' s inability to take into account human nature , they quickly began to destroy Earth . GENIEs became self - replicating in a way , a person merely had to wish for their own in the presence of GENIE , and the original GENIE made one for them . With everyone having a GENIE , power sources on Earth were quickly drained . People also began wishing harmful things on one another , and wishes could not be regulated . Some GENIEs brought their owners back to Arabian times and became the inspiration for the genie legends from that time period . Attempts to stop the use of GENIEs proved futile . Laws could not be passed and enforced , as someone would merely wish the law away . GENIEs themselves could not be wished away despite being able to be wished into existence . People considered wishing GENIEs to never have been invented , but , fearing a destructive paradox , abandoned the idea . An idea did come about though , as a group of people found the earliest make of GENIE they could , made in May of 2375 , and used it to find a way around the paradox . Realising the amount of power it would take , they drew energy from the sun and wished that time be turned back to the day it was first created . Thanks to the enormous amount of power at its disposal , it granted that wish , therefore cancelling out the existence of all other GENIEs . It was known , however , that no GENIE could cope with using the power of the sun , and it burnt up . The heat from its destruction set fire to the lab it was created in and destroyed all research into the project . The GENIEs that had been sent back to Arabian times were erased as well , but echoes and ripples of the timeline they came from remained and mystics and wisemen continued to remember them , leading to the present - day genie legends . However , Vanessa ' s GENIE still existed since it had transported her to Rome on April 17 , 2375 . Being the prototype , it existed before the turning back of time and the nullifying of all other GENIEs . While speaking on her phone with a friend about a documentary she saw on television , she wished she could live in Ancient Roman times . Unbeknownst to her , the prototype GENIE was in the room and , with a thunderous roar , both her and the GENIE were transported back in time . Eventually , during the Doctor and Rose ' s search for Ursus , they come across the GENIE in the form of the Roman god dess Minerva . The Doctor , sensing its guise , wished for it to show its true form , to which the GENIE had to comply . After dealing with the ensuing chaos , the Doctor and Rose returned Vanessa to her own time and took the GENIE with them until they could figure out what to do with it . It was Rose , however , that found the solution : she wished for the GENIE ' s freedom . With a final wish from Rose for the GENIE ' s sake , the GENIE disappeared from the console room to an unknown place in space and time to find a peaceful existence for itself , choosing whether or not it would fulfil a wish . The first creature it came across was a guinea pig - like alien . Upon asking if it had a wish , it squeaked , and the GENIE produced its wish : a large carrot - like vegetable . The GENIE concluded that it would be happy there . In the future , Vanessa ' s father ' s laboratory was still destroyed , but she didn ' t remember the Doctor ' s warnings about not getting her father to try again and contemplated asking him to make her another GENIE as a result instead .
