Why Yveltal? Y NOT?
despite his name sounding like it was put together as a random series of letters beamed down from space by the Planet of Blue Men in Corduroy Pants, Yveltal is alright.
For one thing, dude looks like a Y. that's important. there's some nice radial symmetry going on, and he even folds up into a neat little ball or something.
He's got a striking color scheme that, while perhaps a little too messy with those black veins, is still actually pretty simple in its structure. Red on the inside, black on the outside, add some funky claws and there you go. Plus I will never not dig those fur collar thingies.
