Quetzalcoatl is a deity and mythical hero from real-life Mesoamerican culture.
Quetzalcoatl is an ancient Mesoamerican serpent deity which was prevalent in South America though it is possible there were multiple Quetzalcoatls or that it could assume multiple forms simultaneously. Several structures and structures were built in Quetzalcoatl's likeness. At some point, it was affiliated with the Temple of the Crystal Skull in the Lost River Delta of Cusco, Peru. Quetzalcoatl assisted the crystal skull in defending the temple, filling it with snakes and fighting off trespassers.
Other temples dedicated to the serpent god were located in Teotihuacan in modern Mexico. Some of these temples belonged to the Olmec civilization under the Babylonian conquerer Azerim, a disciple of the inter dimensional entity Marduk. Quetzlcoatl was summoned by the Olmec king to defend part of the Infernal Machine which could be used to enter the dimension of the Aetherium where Marduk resided.
In 1931, the serpent encountered archaeologist/adventurer Indiana Jones when he excavated the Temple of the Crystal Skull. Due to his crippling fear of snakes, Jones refused to fight Quetzlcoatl or its snake minions and left several tourists of the temple to fend for themselves against it. Jones encountered the serpent god once again in 1947 while hunting for the Infernal Machine's pieces and used the temple's spy traps to kill the snake (or at-least that form of it).
Appearances and allusions
Quetzlcoatl is a minor antagonist in this attraction, appearing in the serpent chamber to attack Indiana Jones and his guests on behalf of the Crystal Skull. Depictions of Quetzlcoatl are also prevalent throughout the queue for this attraction. A board left by Indiana Jones brings up searching for glyphs of Quetzlcoatl among other deities in the temple.
The Mexico pavilion's Pyramid of the Mexico is modelled after the real life Aztec Temple of Quetzalcoatl in Teotihuacan, Mexico. As a result, statues depicting several feathered serpent heads decorate the pyramid.
El Rio del Tiempo
A priest dressed as the feathered serpent appeared in this defunct attraction. The priest would depict the rivalry between Quetzalcoatl and Tezcatlipoca.
