Gordon Lethbridge-Stewart (Inferno Earth)

Gordon Lethbridge-Stewart, also known as the Director, was the father of James and Alistair Lethbridge-Stewart on the Inferno Earth. Unlike his main universe counterpart, Gordon did not die in World War II, as that war did not happen in his universe. By 1959 he was the Director of External Security for the British government. (PROSE: The Face of the Enemy, The Schizoid Earth)

Upon Alastair Lethbridge-Stewart's arrival in his reality in 1959, the two were introduced. (PROSE: The Schizoid Earth) Gordon took the boy under his wing, indoctrinating him into the RSF, drugging him heavily, and manipulating him into "the perfect fascist soldier". (PROSE: Ashes of the Inferno)

By the end of the 1960s, Gordon's hunger for power had placed him in office as Leader of the British Republic. (PROSE: Night of the Intelligence)

This all stood in contrast to an account where the Doctor, when visiting the Inferno Earth, (TV: Inferno) recognised the face of the Leader as one of the faces he was offered at his trial, prompting him to realise that the dictator was none other than an alternative third self of his. (TV: The War Games, PROSE: Timewyrm: Revelation) It was not unheard of, it is worth noting, for Time Lords to regenerate, or consider regenerating, into forms identical to preexisting individuals. (TV: Destiny of the Daleks, The Girl Who Died).

He died in the volcanic catastrophe that struck Great Britain in the aftermath of I-Day. (PROSE: The Face of the Enemy)
