Mulder is known for his unwavering belief in the existence of aliens and his catchphrase, "The truth is out there." 2. **Dana Scully** - Portrayed by Gillian Anderson, Dana Scully is also an FBI Special Agent, partnered with Mulder to provide a scientific and skeptical perspective on the X-Files. She is a medical doctor with a background in forensic science, which makes her a perfect foil to Mulder's more credulous nature.

Initially presented as an ambiguous character, Skinner eventually becomes their ally. Despite facing political pressure from higher-ups within the FBI and other government entities, Skinner often provides key support to the agents, helping them continue their work on the X-Files. Additionally, there are several recurring characters who play significant roles over time: - **The Smoking Man / Cigarette Smoking Man (CSM)** - Portrayed by William B. Davis, he is often seen as the primary antagonist, deeply involved in the overarching government conspiracy to hide the truth about extraterrestrial life and other paranormal phenomena. - **Alex Krycek** - Portrayed by Nicholas Lea, Krycek starts as an FBI agent but is quickly revealed to have darker allegiances and becomes entangled with the series' various conspiracies. - **The Lone Gunmen** - A trio of conspiracy theorists named Byers, Frohike, and Langly who often assist Mulder and Scully with their expertise in various fields related to technology and government cover-ups. The dynamic between Mulder and Scully—Mulder the believer and Scully the skeptic—forms the backbone of the show, providing a balance of perspectives on the cases they tackle. Their evolving relationship and the series's ongoing mysteries, including government conspiracies and the search for truth, make "The X-Files" a compelling exploration of science fiction and paranormal phenomena.
