Bad Wolf T-Shirts
Description: After looking into the heart of the TARDIS, the Time Vortex itself filled Rose Tyler, who then temporarily became the Bad Wolf entity. She scattered the two words throughout time as a sign to herself that she was linked to the Doctor, creating a looped ontological paradox.
Description: Bad Wolf was a message scattered in space and time to tempt Rose back to the Game Station to save the Doctor. Later the phrase 'Bad Wolf' became a warning, the TARDIS translated every word to Bad Wolf letting the Doctor know that the universe was in danger.
Description: Beware the snarling wolf, for he's big and bad, with sharp teeth ready to strike fear into the hearts of those who cross his path. This lone wolf carries the spirit of the infamous big bad wolf from the timeless tale of the three little pigs, making him a force to be reckoned with in the world of eshirtlabs.
