Bad Wolf (entity)

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. Newly empowered, she piloted the TARDIS back to the 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 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.

Apart from the Dalek fleet, Rose also destroyed all the Daleks on Satellite Five. She also altered reality to prevent the death of Captain Jack Harkness (DW: The Parting of the Ways). Jack subsequently discovered he could apparently no longer die by any means. (TW: Everything Changes onwards)


 * We do not know if she also restored to life the other victims of the Daleks or restored the damage done to Earth itself by Dalek orbital bombardment.

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)

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