The Leader
Template:Infobox In a parallel universe, the alternate version of the Third Doctor (known to humans by the title of The Leader) was the ruthless dictator of the Republic of Great Britain.
This universes version of the Second Doctor selected one of the bodies offered to him by the Time Lords after his trial. It is unclear exactly how he became president of the British Republic after his regeneration since the Fascist revolution occurred in 1943 at the very latest and the Time Lords had taken specifically away his ability to travel in time. It is possible that he managed to work his way up through the ranks of the ruling Party utilising his superior Gallifreyan intelligence (and possibly hypnosis) until he replaced the previous leader.
His fate remains unknown, human members of the British government (who were unaware of his alien origins) believed that he died in the volcanic catastrophe that struck Great Britain in the aftermath of I-Day. (PDA: The Face of the Enemy)
