 Fox Mulder (seasons 1 – 7, 10, main; season 8 – 9, intermittent lead) is portrayed by David Duchovny. Mulder is an Oxford-educated FBI special agent who believes in the existence of extraterrestrials and a government conspiracy to hide the truth regarding them. He works in the X-Files office, which is concerned with cases marked as unsolvable; most involve supernatural / mysterious circumstances. Mulder considers the X-Files so important that he has made their study his life's main purpose. After his abduction by aliens at the end of season seven, his role in the show diminished and much of his work is taken on by Agent John Doggett. He appeared in an episode of The Lone Gunmen and in both the 1998 film The X-Files and the 2008 film The X-Files: I Want to Believe.
