its just slightly depressing that the creative process was limited to 'let's make pokemon that look like the alphabet". The unown are weird enough. Legendaries shouldn't have to fall into that dreadful cast as well.
you've got a point with Xerneas. The first thing I thought of actually was that movie Princess Mononoke i think it was. If it wasn't that one then it was definitely one of Studio Ghibli's movies. Yveltal though...with that "third wing/hand/phallis?" lol
