Mr Minus
Mr Minus was the name given to a shady auctioneer operating within the Obsidian Mainframe.
Having tapped into the Mainframe's primary operating systems, Mr Minus transformed himself into a purge programme which gave him the ability to manually erase data at a single touch. He attempted to auction off five members of the Kindred of Fel, highly desired telepaths, only to be duped by the Doctor's fake bid. Upon realising that the Doctor didn't intend to pay Mr Minus erased him from the Mainframe, the Doctor was forced to undergo a data regeneration leaing him weakened.
As Mr Minus turned his attention to Clara Oswald and attempted to have her auctioned off, the Doctor devised a plan to overload the Mainframe's systems by selling the TARDIS and causing a bidding storm. The plan succeeded and in the resulting power shortage Clara found an opportunity to free the Kindred of Fel allowing them to use their telepathic powers to make the bidders feel their pain. Now without his connection to the Mainframe, Mr Minus lost his disguise within the database and was exposed as being a member of the Kindred of Fel himself. (COMIC: Pay the Piper)
