I meant the concept, it's story is that of the Ziz which is the hebrew counterpart of the Roc.
Actually it's Aztec...kind of wish people will not confuse the two. Yvetal's name also came from the same god btw...also Therian Thundurus' design like Rayquaza was based off it...Gf must really love the Aztec wind god...
Actually have you ever heard of the story of how the Aztecs thought the spaniards were gods? it was because their wind god was white and bearded...the Aztecs when being converted to Christianity noticed parallels between Jesus and him, like wise for a goddess (beleive it was a sun or Earth goddess) with the Virgin Mary.
I wish there were more info on Aztec mythology...it allows me to see what my ancestors beleived in...though it's more common than your area of knowledge...
Where did you heard of it from? Your contacts? Or your own research?
