@Monkey:
Quetzalcoatl?
He was the Aztec god of war. They had many gods. He was a feathered serpent in god form.
In man form? A redheaded, blue eyed man, which lends to the idea that the Celts visited the Americas long ago. Because the native American people were, as far as I can find, brown eyed, black haired. For them to have chosen blue eyes and red hair randomly, and just happen to chose that of one of the most widespread people of the time is a bit of a ... coincidence.
