Doggett replaces him as Scully's partner and helps her in her search for Mulder, and later involves Reyes, of whom Doggett had professional knowledge.

In 2000, Alvin Kersh assigned him to the X-Files office as Dana Scully's partner after an unsuccessful task force attempt to find missing agent Fox Mulder in " Without ".

However, during a period of time after Scully's cancer went into remission ( season 5 ), Mulder was convinced by Michael Kritschgau that aliens did not in fact exist, and that the government conspirators had merely concocted that threat as a smokescreen, to justify military activities and toy with him.

In the season six episode " How the Ghosts Stole Christmas ", a ghost that seems to know the inner workings of Scully's mind suggests that her source of intimacy for Mulder comes from her desire to always prove him wrong.

In his early appearances, he is seen in the offices of Division Chief Scott Blevins and Assistant Director Walter Skinner, Mulder and his partner Dana Scully's supervisors.

In his first appearance in the series, he oversees FBI agent Dana Scully's briefing and debriefing, and later disposes of evidence Mulder and Scully had brought back from their investigation of an alien abduction.

Initially, Skinner acts solely as a supervisor to Agent Mulder and Dana Scully's investigations of the paranormal.

The season continued on from the 1998 feature film and focused heavily on FBI federal agents Fox Mulder ( David Duchovny ) and Dana Scully's ( Gillian Anderson ) separation from The X-Files, the assignment of new agents Jeffrey Spender ( Chris Owens ) and Diana Fowley ( Mimi Rogers ) to the division, and the demise of the Syndicate — a " shadow government " group attempting to cover up the existence of extraterrestrials — in the two part episode " Two Fathers " and " One Son ".

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.

Krycek plays an important part in several events that are harmful to Mulder and Dana Scully: he assists in Scully's abduction, and murders Mulder's father, William " Bill " Mulder.

He also attempted to separate Mulder and Scully, believing that Mulder threw away a promising career as a criminal profiler, but that Scully's career could still be saved.

Four main characters from the television series appear in the film: David Duchovny, Gillian Anderson, Mitch Pileggi and William B. Davis reprise their respective roles as FBI agents Fox Mulder and Dana Scully, FBI Assistant Director Walter Skinner and the Cigarette-Smoking Man.

As an Assistant Director, he temporarily became supervisor to Agents Fox Mulder ( David Duchovny ) and Dana Scully ( Gillian Anderson ) when they were assigned away from the X-Files division.

After Mulder returned home to his apartment, an application was submitted to the FBI for his reinstatement to the X-files but this was declined by Deputy Director Alvin Kersh, who had been promoted in charge of the X-files shortly after Mulder had been abducted.

It was around this time that Mulder was fired from the FBI by Deputy Director Alvin Kersh, and Scully left the field to teach forensics at Quantico.

In 2000, Agent Doggett was assigned by Deputy Director Alvin Kersh to head up the manhunt to find Special Agent Fox Mulder.

When Mulder and Scully were reassigned to the X-Files office, Kersh continued to climb the ladder, culminating in an assignment as Deputy Director of the Federal Bureau of Investigation.

Despite a defense organized by Walter Skinner with numerous witnesses, the judges sentence Mulder to death.

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.

During this time Doggett and Kersh developed a bitter enmity, similar to the early relationship between Mulder and Walter Skinner.

Having been given the location of a downed UFO, she and Krycek betray The Smoking Man, instead going to FBI assistant director Walter Skinner and Mulder to inform them about the craft.

Skinner is originally the direct supervisor of special agents Fox Mulder and Dana Scully in the X-Files office.

Although he is originally portrayed as a somewhat malevolent character, Skinner eventually becomes a close friend of Mulder and Scully.

At the start of the series, Skinner was unfriendly towards Mulder because of his belief in the extraterrestrial, while throughout the series run Skinner has moved on to respect and agree with Mulder's idea, which is finally proven in " Requiem ", when he saw an Alien spacecraft.

Eventually, Skinner begins trusting Mulder and Scully and becomes their ally, saving both of their lives on multiple occasions.

Six years later, with the X-Files still closed down, Skinner assists Scully in finding Mulder after he goes missing while consulting on the FBI's investigation into the disappearance of a missing agent.

Mulder and Skinner are shown to still be on friendly terms, despite Mulder's animosity towards the FBI for the events following the trial.

Lea continued to play Krycek, who became a nemesis not just of Mulder and Scully but particularly of A. D. Skinner ( Mitch Pileggi ).

Later, when Mulder was abducted by aliens and returned in a death-like state, Krycek attempts to again blackmail Skinner, with the means to save Mulder's life.

In the season eight finale, " Existence ", Krycek is shot between the eyes and killed by Skinner, during an unsuccessful attempt to kill Mulder.

After Skinner fails to track her down, the ghost of X hands Mulder a scrap of paper with her new address on it.

* In the X-Files season 3 finale ( Talitha Cumi ), Mulder gets a call from AD Skinner, who tells him that his mother has been admitted to a hospital in Quonochontaug, where Mulder's family owns a summer house.

In the end, Kersh showed a heroic side during the series finale " The Truth ", when he helped Doggett and Skinner free Mulder from a military prison.

* In The X-Files Season 1 Episode 6 ( Shadows ), Agents Scully and Mulder encounter a poltergeist of a deceased CEO.

The Lone Gunmen authored a news publication called The Lone Gunman ( once referred to as The Magic Bullet Newsletter ; a pejorative reference to the single bullet theory and, like the group's name, a reference to the Kennedy assassination ), to which Mulder loyally subscribed.

He tells Mulder and Scully all he has left to reveal ( including the fact that the aliens are scheduled to invade in 2012 ), and shortly after is finally killed by a missile shot from a helicopter ordered by Knowle Rohrer.

Black Sigatoka, also known as black leaf streak, was named for its similarities with the Yellow Sigatoka caused by Mycosphaerella musicola ( Mulder ), after the Sigatoka Valley in Fiji where an outbreak of this disease reached epidemic proportions from 1912 to 1923.

That evening, Mulder encounters a paranoid doctor, Alvin Kurtzweil ( Martin Landau ), who explains that the five victims were already dead, and that the bomb was allowed to detonate in order to destroy evidence of how they died.

He serves as an antagonist to FBI special agents Fox Mulder ( David Duchovny ) and Dana Scully ( Gillian Anderson ), being a member of the sinister Syndicate the agents seek to foil.

Although the Syndicate's goals are opposed to those of Fox Mulder ( David Duchovny ) and Dana Scully ( Gillian Anderson ), the Well-Manicured Man will, at times, aid them with clues or information, believing that letting out a certain amount of information would help to keep the two close, and consequently allow for them to be controlled.

In the Dutch short film " De Blauwe Bus " ( The Blue Bus ), which was released in 2009, he was portrayed by Jan Mulder.

Details of some missions make humorous references to various games or movies, using parodical names, such as Boston Flowers ( Austin Powers ), or Mox Fulder ( Fox Mulder ).

Portrayed by the American actor Robert Patrick, Doggett was a main character from the eighth to ninth seasons ( 2000 – 2002 ), replacing David Duchovny's character Fox Mulder.
