Behind the scenes

A parallel universe's Sauron appeared as part of an alliance of antagonists in the crossover video game, LEGO Dimensions. The alliance also included licensed appearances by the Daleks. However, due to a branching storyline, the game is not considered a valid source by this Wiki.
In J. R. R. Tolkien's Legendarium, Sauron's domain is the Land of Mordor, referenced as a fictional location in the 1988 comic story Nostalgia Corner, but no link has yet been drawn between the Doctor Who Sauron and Mordor in a valid source.
