So, after agonising over gijinkifying Xerneas, I watched Brave and sketched out Elinor, after which I realised that I associate deer with Celtic regions. Therefore, it made sense to give it a Celtic air. Couldn't decide between making it male or female, so I did both and just coloured the woman. The drawings next to the man were supposed to be antler-pattern ideas for his cloak, instead of giving him dreadlocks too.
For Yveltal, Bulbapedia said its name could be derived from a 'quetzal', which made me think of Quetzalcoatl and by extension Mesoamerican culture. So even though Yveltal looks nothing like an Aztec, that's the idea. *shrug*
And then there's Little Chespin Riding Hood.
