The X Files S010

The second season of the science fiction television series The X-Files commenced airing on the Fox network in the United States on September 16, 1994, concluded on the same channel on May 19, 1995, after airing all 25 episodes. The series follows Federal Bureau of Investigation special agents Fox Mulder and Dana Scully, portrayed by David Duchovny and Gillian Anderson respectively, who investigate paranormal or supernatural cases, known as X-Files by the FBI.

The second season of The X-Files takes place after the closure of the department following the events of the first season finale. In addition to stand-alone "Monster-of-the-Week" episodes, several episodes also furthered the alien conspiracy mythology that had begun to form. Season two introduced several recurring characters—X (Steven Williams), an informant to Mulder; Alex Krycek (Nicholas Lea), Mulder's partner-turned-enemy; and the Alien Bounty Hunter (Brian Thompson), a shape-shifting assassin.

The eighth season of the American science fiction television series The X-Files commenced airing in the United States on November 5, 2000, concluded on May 20, 2001, and consisted of twenty-one episodes. Season eight takes place after Fox Mulder's alien abduction in the seventh season. The story arc for the search of Mulder continues until the second half of the season, when a new arc about Dana Scully's pregnancy is formed. This arc would continue, and end, with the next season. The season explores various themes such as life, death, and belief.

Season eight was received well by critics but got more mixed reviews by fans and viewers, since David Duchovny elected to return only as an intermittent main character, meaning that he appeared in only half of the episodes. Duchovny was initially replaced by Robert Patrick who played new central character John Doggett. Duchovny appeared for only twelve episodes in season eight, and reduced his time on The X-Files dramatically in season 9. "This Is Not Happening" marked the first appearance of Annabeth Gish as Monica Reyes, who would become a main character in season 9 as Doggett's new partner in the X-Files office.

The first season of the science fiction television series The X-Files commenced airing on the Fox network in the United States on September 10, 1993 and concluded on the same channel on May 13, 1994 after airing all 24 episodes.

The first season introduced main characters of the series, including Fox Mulder and Dana Scully who were portrayed by David Duchovny and Gillian Anderson respectively, and recurring characters Deep Throat, Walter Skinner and The Smoking Man. The season introduced the series' main concept, revolving around the investigation of paranormal or supernatural cases, known as X-Files, by the Federal Bureau of Investigation; it also began to lay the groundwork for the series' overarching mythology.

The ninth and final season of the American science fiction television series The X-Files commenced airing in the United States on November 11, 2001, concluded on May 19, 2002, and consists of twenty episodes. Season nine takes place after Fox Mulder's leave after the events of the eight season finale, "Existence". Mulder is in hiding during the whole season, with the exception of the series finale, "The Truth".

Season nine received mixed reviews by critics and garnered negative reaction from many long-time fans and viewers, partially because David Duchovny did not make regular appearances on the show, after fulfilling his contract in the previous season. Duchovny appeared in only two episodes this season. Previous recurring characters Monica Reyes (Annabeth Gish) and Walter Skinner (Mitch Pileggi) were billed as main characters for this season, which follows Dana Scully (Gillian Anderson), John Doggett (Robert Patrick) and Reyes on their hunt to reveal a government conspiracy who are creating "Super Soldiers".

The fifth season of the science fiction television series The X-Files commenced airing on the Fox network in the United States on November 2, 1997, concluding on the same channel on May 17, 1998, and contained 20 episodes. The season was the last in Vancouver, Canada; subsequent episodes would be shot in Los Angeles, California. In addition, this was the first season of the show where the course of the story was planned in advance, due to the 1998 The X-Files feature film being filmed before it, but schedule to be released after it aired.

The fifth season of the series focused heavily on FBI federal agents Fox Mulder's (David Duchovny) loss of faith in the existence of extraterrestrials and his partner, Dana Scully's (Gillian Anderson), resurgence of health following her bout with cancer. New characters were also introduced, including agents Jeffrey Spender (Chris Owens) and Diana Fowley (Mimi Rogers) and the psychic Gibson Praise (Jeff Gulka). The finale, "The End", led up to both the 1998 film and the sixth season premiere "The Beginning".
