speaking of which they had this to say about yveltal and xerneas which i thought was pretty interesting (roughly translated):
The chances are that Yveltal is based on the mythological being Yatagarasu, the three clawed raven which is said to represent divine intervention. In Japanese history, the emperor Jimmu Yatagarasu guide to current Nara prefecture in Japan. Nara is a city twinned with Versailles says (see below), and whose divine messenger came another forest, the white deer of Nara. Both are considered so legendary divine messengers of Nara prefecture.
