Fox Mulder

FBI Special Agent Fox William Mulder is a fictional character in the Fox science fiction-supernatural television series The X-Files, played by David Duchovny. Mulder's peers consider his (often correct) theories on extraterrestrial activity as spooky and far-fetched. He also has a photographic memory and is partially colorblind. With his FBI partner Dana Scully, he works in the X-Files office, which is concerned with cases with particularly mysterious or possibly paranormal circumstances that were left unsolved and shelved by the FBI. Mulder was a main character for the first seven seasons, but was limited to a recurring character for the following two seasons. He returns as a main character for the tenth season.
