Fictional universe in Avatar
Mountain Banshee (Ikran in Na'vi language) is an airborne predator who lives in mountainous territory on Pandora.  Na'vi warriors attempt to bond with a Banshee, a dangerous and required rite of passage.  A Banshee bonds to a Na'vi warrior for life.  Page spent the most time designing the Banshee for the movie so it would be convincing when it flew or perched.  The designer said, "The hardest thing of all was having a Na'vi on top of it and flying it. You had to backwards engineer it. It was like designing and engineering an aircraft."  Barlowe, who contributed to the Banshee's design, was influenced by manta rays and skates as well as relatively little-known pterosaurs and plesiosaurs that had "many, unique aerodynamic and hydrodynamic" characteristics. Like the color scheme for the Great Leonopteryx, color schemes based on Earth animals were used for various Banshees, though Page was inspired by Art Nouveau prints to warp the schemes so they would not look familiar to movie audiences.
