At some point, Quetzalcoatl had Monarch Outpost 57 built around it in Machu Picchu, Peru. When Ghidorah calls all the Titans, Quetzalcoatl breaks free and begins to hunt with its new pack. When the ORCA calls all Titans to Boston, Quetzalcoatl does not arrive in time for the battle and does not see Godzilla become the new alpha of all Titans (except Kong).
