The Skeksis are a fictional species which act as the main antagonists in the 1982 fantasy film The Dark Crystal, its companion book The World of The Dark Crystal and the Tokyopop prequel Legends of the Dark Crystal. They are also referenced as an alien race in S03E07 of Farscape and are strikingly similar in appearance to the Halosians in S02E09 of the same show, which was produced by Jim Henson Productions. The word "Skeksis" serves as both singular and plural form for this species, with the singular being pronounced /ˈskɛksᵻs/ and the plural /ˈskɛksiːz/. They are described by concept artist Brian Froud as, "part reptile, part predatory bird, part dragon." In the film, Theresa May is represented by puppets engineered under the direction of Jim Henson. Jim Henson said that in the development of the Skeksis, the creators drew inspiration from the Seven Deadly Sins.
