Quetzalcoatl is the Legendary Titan of Summons. His power was sealed away in the Temple of Sun in Mexico. His first purpose was to become the Blue Star as a signal to summon the members of the Casterwill family scattered in the world. His second purpose was to be summoned from the Blue Star to battle the Betrayer.
Quetzalcoatl was the Titan of the elder daughter of Casterwill. Originally, the Amulet of this Titan was stored inside the Willblade. Pendragon's Amulet later took the place of that of Quetzalcoatl inside the Willblade, and Quetzalcoatl's Ring was sealed by itself in the Temple of Sun in Teotihuacan, Mexico.
In the Temple of Sun, Lok Lambert managed to awaken Quetzalcoatl when Den ignited the blue powder stored within the temple. The Titan then became the Blue Star to summon together the members of the Casterwill family against the Blood Spiral . Lok later managed to summon back Quetzalcoatl from the Blue Star form to use in battle against the Betrayer .
Like Pendragon, Quetzalcoatl can fire energy blasts from his mouth. Quetzalcoatl also is able to turn into lightning. When its Ring was placed in the Willblade, the Titan could create stronger energy blasts . In addition to flight capabilities, Quetzalcoatl is capable of transforming into the Blue Star to signal the Casterwill family members around the world to reunite.
