As new content is released, there are more possible combinations of Doctors, companions, and foes, so that there are many possible combinations to create stories. One example of this is the Fifth Doctor and Donna Noble battling a Crack in Time. With the future inclusion of Locations, this can occur in the TARDIS. Recent updates have added Susan Foreman, Rose Tyler's Bad Wolf persona, and the Statue of Liberty Weeping Angel. Future updates will include Jackie Tyler, Sally Sparrow, and Vastra.
