Bad Wolf meme Bad Wolf was a meme created by " the Bad Wolf " to inspire Rose Tyler to save the Ninth Doctor from the Game Station . ( TV : " The Parting of the Ways " ) It also prefigured the return of Rose into the Tenth Doctor ' s life , following his regeneration , as well as the crisis they would face together . ( TV : " Turn Left " ) " Bad Wolf " was thus both warning for the end of the universe and signpost . Timeline . The Moment . When the consciousness of the Moment took form , it selected the form of Rose Tyler as the Bad Wolf entity . When the War Doctor commented that he could kiss her for giving him a way out of the dual - genocide he was prepared to commit , she remarked , " That ' s definitely gonna happen . " The Tenth and Eleventh Doctor s , having already heard the Bad Wolf meme , were visibly surprised to hear his past self mention " Bad Wolf girl " , as she was only visible and audible to the War Doctor . Due to the timelines rearranging themselves , the War Doctor ( and his immediate successor ) retained no memory of Bad Wolf . ( TV : " The Day of the Doctor " ) During the Doctor ' s ninth incarnation . TARDIS graffiti was the Doctor ' s first known direct encounter with the phrase . The phrase was most commonly found in graffiti during the 20th and 21st centuries ( TV : " Aliens of London " , " Father ' s Day " , " The Parting of the Ways " , " Captain Jack Harkness " ) , but the first chronological occurrence was in 1592 , where a tavern sign showed a picture of a wolf ' s head and the initials " B . W . " . ( COMIC : " A Groatsworth of Wit " ) It later occurred in 1869 , when Gwyneth , a parlour maid and clairvoyant , looked into Rose ' s mind and declared she had seen " the Big Bad Wolf " .

The Moxx of Balhoon told the Face of Boe that the current situation was " the Bad Wolf scenario " . ( TV : " The End of the World " ) Bad Wolf was on one of the posters for " ENERGIZE " . ( TV : " Father ' s Day " ) It appeared in other languages as well .

( TV : " Boom Town " ) A group of weapons on the Fluren Temporal Bazaar on Fluren ' s World held a banister labelled " Bad Wolf Bargains .

( TV : " Dalek " ) . Another company , Bad Wolf Holdings , was a part of the Consortium in New Vegas in the 23rd century . ( AUDIO : " Night of the Whisper " ) The phrase became more common in the years 199 , 909 to 200 , 100 , when the Dalek - controlled Bad Wolf Corporation and the television channel " Bad WolfTV " made use of it ( TV : " The Long Game " , " Bad Wolf " / " The Parting of the Ways " ) It turned out that to save the Doctor ' s life , Rose Tyler had opened the Doctor ' s TARDIS , looked into its heart and become the Bad Wolf entity . She then used her seemingly unlimited reality - warping powers to destroy the Dalek Imperial Fleet and spread the Bad Wolf meme throughout space and time , so she would realise she could use the TARDIS to save the Doctor ( thereby creating an ontological paradox ) . Rose was later restored when the Doctor saved her life by taking the Time Vortex energy from the heart of the TARDIS out of her body and regenerating . ( TV : " The Parting of the Ways " , " Children in Need Special " ) One of Mickey Smith ' s video games was entitled Bad Wolf . ( PROSE : " Winner Takes All " ) After Bad Wolf .

( TV : " The Christmas Invasion " ) In 1879 , the Host , a human boy under control of a werewolf ' s bite , stated that Rose had " something of the wolf about her . " Because the wolf was also very hostile , it could be considered a literal interpretation of the Bad Wolf . ( TV : " Tooth and Claw " ) The Torchwood Institute ' s files on Rose Tyler were corrupted by the Bad Wolf virus ( TV : " Love & Monsters " ) and , after the Doctor and Rose had been separated in different universes , the last hole through the Void linking them led into " Dårlig Ulv Stranden " ( Bad Wolf Bay ) in Norway . ( TV : " Doomsday " ) It also appeared in the year 5 , 000 , 000 , 053 , inside a New New York car .

On a parallel Earth , Donna Noble was sent back in time to make her past self in the " main " reality turn left at a junction on Little Sutton Street . She did this by running into a lorry , creating a traffic jam . As Donna died , Rose told Donna to tell the Doctor two words : " Bad Wolf " . The " real " Donna vaguely remembered the words whispered to her other self , which she told to the Tenth Doctor . Immediately , the whole of Shan Shen was covered with the words " bad wolf " . Even the Doctor ' s TARDIS was altered to include the phrase on all of its exterior signs . Donna asked what this meant , and the Doctor told her it meant the end of the universe . ( TV : " Turn Left " ) By the time the Doctor and Donna returned to Earth , however , the Bad Wolf words had disappeared from the TARDIS . ( TV : " The Stolen Earth " ) Other appearances .
