They can be called "Crap basket white" and "vomit sack black" for all I care. We got sequels, which is cool. What wasn't cool was that the story wasn't nearly as good as the originals, but I digress.
ALthough, you know, now that I think about it, we might be getting sequels anyway. There's more than one form to Zygarde, just like with Kyurem.
