Federal Bureau of Investigation

The Federal Bureau of Investigation (FBI) is the primary investigative arm of the United States Department of Justice, serving as both a federal criminal investigative body and a domestic intelligence agency. The FBI has investigative jurisdiction over violations of more than 200 categories of federal crimes.

The FBI served as a major backdrop on the television series The X-Files. The series revolved around Special Agent Fox Mulder, a conspiracy theorist who was considered "spooky" by his peers. Fox was a specialist in cases revolving around unexplained phenomena, often referred to as "x-files". Assisting him in his endeavors was Special Agent Dana Sculley, a forensic scientist who did not share Fox's appreciation for the inexplicable. Initially, Sculley was assigned to Mulder for the sake of discrediting him, and though she always remained a skeptic when it came to the existence of UFOs, she became a loyal and trusted companion to Mulder, frequently risking her own career and life to save his.

The FBI was also used as a focal point in the 2009 television remake V. The main character from the series, Erica Evans, was an FBI agent who worked under New York section chief Paul Kendrick. They played a vital role in trying to maintain peace between the citizens of Earth and a race of aliens who called themselves Visitors. Though the Visitors gained momentous support amongst the populace of Earth, there were many factions that rallied against them, not the least of which was the terrorist cell known as the Fifth Column. Paul Kendrick placed Erica Evans in charge of a special task force aimed at bringing down the Fifth Column, never realizing that she was in fact one of their number.
