Master Brain
From Tardis Wiki, the free Doctor Who reference
Master Brain was a futuristic computer in the Land of Fiction who had enslaved the Master of the Land of Fiction and tried to do the same to the Doctor. (DW: The Mind Robber)
- The origins and ultimate purpose of the Master Brain remains unknown.
- Due to the fact that the Gods of Ragnarok ultimately creatred the land of fiction (implied in Conundrum), it could be speculated that they probably created it.
