Biography
Having had his TARDIS placed beyond his reach under unknown circumstances, the Master spent his time stuck on Earth through the 1970s right through to 1997 when the Doctor is sent to Earth by the Time Lords. Under Ke Le alias, the Master had to live through the series of crises and disasters befell this Earth in the 1970s. He worked first for the United Nations and then defected to China after being sent there to assist against alien parasites. He turned the parasites into a way of brainwashing political prisoners into zombie-like soldiers organized into Ke Le Divisions. (DWU: Sympathy for the Devil)


 * In the main timeline, the Master had used an alien parasite to create the Keller Machine. (DW: The Mind of Evil)

Losing favour with the new Chinese government in 1997, he fled to Hong Kong to allegedly defect back to the West. He regenerates when he crashes an experimental cloaked plane on Hong Kong, and tried to gain the last of the parasites. China intended to wash their hands of the Ke Le Divisions by destroying the other parasites, and the Master realised this would cause the Divisions to go insane under the weight of their returned memories; with the last parasite, he intended to seize control of the Divisions and the country ("I'll save the world from anarchy overnight").

When the Doctor arrived, the Master showed a genuine bitterness over having to live on an Earth where the Doctor hadn't been presented for thirty years; he brought up scores of atrocities (both real-world and alien related) that the Doctor had failed to stop, accusing him of letting entire cultures and races die from missing the big picture, choosing the wrong sides, and simply not turning up. Eventually, he agreed to help the Doctor and UNIT destroy the last parasite - allowing them to believe nothing bad would happen - in return for being taken off Earth in the TARDIS, while secretly planning to betray everyone. Unfortunately for him, the Doctor had anticipated this and tricked the Master into being left in Hong Kong as the TARDIS departed.

In a desperate attempt to be evacuated from the city, he admitted to UNIT's Colonel Brimmicombe-Wood that the Ke Le Divisions would go insane once the last parasite was destroyed. By this point it was too late, and the Master was last heard giggling as the Divisions massacred Hong Kong. (DWU: Sympathy for the Devil)
