Samantha Mulder Abduction Little Green Men

Samantha Mulder's abduction, the impotus for Mulder's research into the paranormal. (TXF: "Little Green Men")

The mythology, or mytharc, is the overarching story developed in a series of episodes of The X-Files where Mulder and Scully investigate and expose an international conspiracy by an organization known as the Syndicate to develop a human/alien hybrid and suppress knowledge of the existence of extraterrestrials who plan to colonize Earth.

Common themes include:

It should be noted that some key mythology characters also appear in Monster of the Week episodes; notably, Deep Throat, X and the Cigarette Smoking Man each appear in episodes which involve government activities. Furthermore, as his role expanded, Walter Skinner appears in more Monster of the Week episodes.

There are 68 episodes in the Mytharc from the original run (including the movie and the feature length finale as one episode). There are 5 episodes in the new mini-series, bring the total to 73. Season premieres and finales always focus on the mythology arc, with the premieres typically continuing on the events of the previous seasons finale.
