Bad Wolf (entity)


 * For other uses of Bad Wolf, see separate page.

After looking into the Heart of the TARDIS, Vortex energy (if not the Time Vortex itself) filled Rose Tyler, who then temporarily became the Bad Wolf entity.

Rose Tyler as the Bad Wolf
Newly empowered, she piloted the TARDIS back to the Ninth Doctor. A nimbus of light surrounded her and shone through her eyes. Rose's natural London accent vanished. She also possessed the destructive and creative powers of a goddess, enabling her to destroy an entire Dalek fleet and have an enormous influence over time and space.



While possessed of these gifts, the entity set out to spread the Bad Wolf meme through many worlds and times. In this way, the Ninth Doctor and Rose's past selves would eventually follow the clues that would enable them to defeat the Daleks, creating an ontological paradox in the process. The Bad Wolf Entity destroyed and Dalek fleet and all the Daleks on Satellite Five. She also altered reality to prevent the death of Jack Harkness (DW: The Parting of the Ways).

Jack would later discover he could apparently no longer die by any means, and it would take him nearly a century and a half of subjective time before he finally learned that she was responsible. (TW: Everything Changes onwards, plus DW: Utopia)

The Doctor restored Rose's human self by absorbing the Vortex energy into his own body, a process that would prove destructive to his cellular structure and so prompt the Doctor's next regeneration. (DW: The Parting of the Ways)

Subsequent mentions

 * Upon her meeting with the werewolf host, that entity noted that Rose also had "something of the wolf" in her. (DW: Tooth and Claw)


 * While on the Valiant, the Master commented to the Doctor he "once had companions who could absorb the time vortex".


 * Professor Yana overheard the Tenth Doctor talking about this with Captain Jack Harkness during the events of Utopia. It is most likely one of the things that prompted his realisation that he was, indeed, the Master.


 * An unknown force, presumably the Bad Wolf entity, changed all the banners and signs in the Shan Shen market place to read "BAD WOLF." (DW: Turn Left) This warned the Doctor and Donna Noble of the impending danger of Davros and the Daleks. (DW: The Stolen Earth)


 * The Torchwood files concerning Rose were damaged by the "Bad Wolf virus." This may be the virus the Doctor gave Mickey or an action of the Bad Wolf entity. (DW: Love & Monsters)

Behind the scenes

 * Though Billie Piper portrayed Rose infused with the Bad Wolf entity in both body and voice, another actress (or possibly actor) recorded the dialogue and the final cut involved both voices mixed together.
