The X-Files episode titled “The Host” features the creature called the Flukeman.
“The Host” is the second episode of The X-Files’ second season and originally aired in 1994, despite the series beginning in 1993. The episode follows FBI agents Fox Mulder and Dana Scully as they investigate gruesome deaths linked to a sewer system. The monster, nicknamed the Flukeman, is a humanoid parasite covered in fluke-like features.
The episode is sometimes associated with Pandora-themed trivia because its plot centers on an apparently contained biological danger emerging into the public environment. However, it does not feature the mythological Pandora or a character named Pandora. Its title is simply “The Host.”
“The Host” was written by Chris Carter and directed by Daniel Sackheim. It became notable for its creature design and body-horror imagery, helping establish the darker tone of the show’s second season.
