What is the name of the actor who played the alien bounty hunter?

Brian Thompson played the alien bounty hunter on The X-Files. His imposing height and distinctive appearance made him a memorable recurring presence in the show’s alien-conspiracy mythology.

The character is an extraterrestrial operative capable of shapeshifting into human forms. The bounty hunter usually appears as a dangerous enforcer pursuing escaped aliens or protecting the larger colonization project. Rather than having one consistent human identity, the character is identified primarily by the role he performs within the alien hierarchy.

Thompson portrayed the alien bounty hunter in nine episodes between 1995 and 2000. The role connected him to major mythology stories across several seasons, including episodes involving alien rebels, government conspiracies, and the long-running threat of colonization.

The other options are associated with different X-Files performers or characters. Bruce Harwood and Tom Braidwood played members of the Lone Gunmen, while Orestes Matacena appeared in the series in another role. Thompson also worked extensively in science-fiction television, including Star Trek productions, but the bounty hunter remains one of his signature X-Files parts.
