Quetzalcoatl: Winged Serpent (翼ある蛇ケツァル・コアトル, Tsubasa aru HebiKetsaru Koatoru?) is the Noble Phantasm of Quetzalcoatl. This Noble Phantasm is the reason Quetzalcoatl has the Rider-class. She summons the Cretaceous-era pterosaur Quetzalcoatlus which is named after herself, and rides it. In reality, it is a Phantasmal Species on the Phantasmal to Divine Beast level which is far more powerful than the Quetzalcoatlus that lived in the Cretaceous period. Quetzalcoatlus is known as the largest flying animal of all time. When its true name is invoked, Quetzalcoatlus is able to control massive rain and thunderstorms.
