- "Uy ah ual ing ual ing wetail."
- ―Quetzalcoatl
One of the "giant aliens" that Nicholas Ballard encountered when he found a crystal skull at a dig in Belize. He was encountered by SG-1 in 2000 during a mission to P7X-377 in which Daniel Jackson discovered a second Crystal skull identical to the one found in Belize. After returning to P7X-377, and replacing the skull, SG-1 sans Teal'c and Nick Ballard were dimensionally shifted so that they might meet the Omeyocan, and were greeted by Quetzalcoatl.
