The Skeksis are a fictional species that serves as the main antagonists in the 1982 film The Dark Crystal and its related franchise. The word "Skeksis" serves as both singular and plural form for this species. They are described by concept artist Brian Froud as, "part reptile, part predatory bird, part dragon". The Skeksis are 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.
