El Jefe

"El Jefe" was a nickname for a renegade member of a mythical race of trans-temporal oppressors (PROSE: The Rise and Fall of Señor 105) from the previous universe. (PROSE: First Meetings)

"El Jefe" was not his real name but a demeaning nickname, given to him by Theo Possible and interpreted through Señor 105's translation technology. (PROSE: The Rise and Fall of Señor 105)

History
For four hundred years, El Jefe worked as a minor functionary for the Lords Temporal, the most important race in the Clockworks. He helped out in the Monkey God crisis by pressing buttons and moving dials. Bored of his insignificant life among his own people, Jefe stole a wordship and ran away to pursue a life of adventures.

While he had been aware of her for a while, Jefe first met Iris Wildthyme in a back alley on Hyspero. Iris would later pretend to have met Jefe in Paris during the revolution. (PROSE: First Meetings)

Jefe visited the Witch's Tipple in Hertfordshire for a 1973 Christmas party and waltzed with Iris Wildthyme. (PROSE: Iris at the V&A)

Appearance
Jefe was an older grey-haired man who wore purple silk capes. (PROSE: Iris at the V&A) Iris once described Jefe as a "white-haired gollum... comfortable only in the shadows and within secret, quiet spaces". He used a cane. (PROSE: First Meetings) Panda thought that Jefe looked like a dandy. (PROSE: Iris at the V&A)

Behind the scenes

 * El Jefe is clearly intended to be a parody of the First Doctor. This has been repeatedly confirmed by the authors: in Blair Bidmead's short story Significant Others from the charity anthology A Target For Tommy, the First Doctor is shown to remember El Jefe's meeting with Theo Possible from El Jefe's point of view; and in Stuart Douglas' short story When Iris Met Billy, an edited version of First Meetings published in A Second Target For Tommy, the words "El Jefe" are replaced with "the Doctor", who is also referred to as "Billy" in reference to William Hartnell.
 * El Jefe appeared in Blair Bidmead's Señor 105 novel By the Time I Get to Venus, which was later reprinted in The Rise and Fall of Señor 105.
