Leeds/Other realities
Alternate counterparts of Leeds existed in other realities. These locations shared similarities with Leeds from the Doctor's universe, despite existing in parallel universes or alternate timelines.
Aborted timelines
Graham Dilley Saves the World
In a subsequently erased timeline, Graham Dilley - an English cricketer - failed to catch a ball in the Third Test of the Ashes, hosted in Leeds, after being distracted by Tegan Jovanka. This caused England to lose and sparked civil unrest. Events were later reverted by the Fifth Doctor, Peri Brown and Erimem. (PROSE: Graham Dilley Saves the World)
Parallel universes
Inferno universe
A version of Leeds existed in a parallel version of Earth in which Great Britain was a fascist republic. After the disastrous failure of the Inferno Project, seismic disturbances were reported as far north as this version of Leeds. (TV: Inferno)
Donna's World
In a parallel world, Donna Noble and her family were relocated to the city following London's destruction by a replica of the Titanic. Donna was extremely indignant at being forced to live there. After the activation of the ATMOS devices by the Sontarans, Donna and Rose Tyler watched from a local park as the sky cleared of gas. (TV: Turn Left)
