We also need a satanic pokémon, then. Y'know, the whole dark vs. fairy type thing.
I think Houndoom fits in that category somewhat. :p We need more satanic Pokemon though. I also saw Gardevoir as angelic, seeing as she was based off on a guardian angel, and she's also fairy-type too. Couldn't really imagine an actual angelic Pokemon, based on an actual angel. It's probably interesting to see how it turns out if they ever do make one of the sort.
