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.

The origin of the name (why it was chosen as opposed to another term) has yet to be revealed.

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 entity may have also left a similar message in the Doctor's future (DW: Turn Left). The Bad Wolf Entity destroyed the Dalek fleet and all the Daleks on Satellite Five, including the Dalek Emperor. 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) As the instigator of Jack's immortality, Bad Wolf was therefore indirectly responsible for the event known as Miracle Day on Earth (TW: The New World, et al).

Rose was unable to hold the power permanently without burning up, and 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. Rose subsequently lost most of her memory of her time as the Bad Wolf, saying that the knowledge had been locked like it was "forbidden", and that trying to repeat it could cause the universe to blow up.
