FBI Special Agent Fox Mulder
is a character in The X-Files
and The Lone Gunmen
, two science fiction shows about a government conspiracy to hide or deny the truth of Alien existence. Mulder's peers consider his (often correct) theories on extraterrestrial activity as spooky and far-fetched. 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, as he's referred to, is often reserved but highly observant.
