My second idea is what got me a little more. I'll start with a story...
A beautiful contest Pokémon with many beautiful ribbons was abandoned by its trainer at an altar. She waited an eternity for her trainer's return among the bells. She haunted the altar in the afterlife, and grew to be the most beautiful bell of them all.
Note: The story is just what the little village people came up with, I don't suggest that it is a legendary. It looks pretty feminine and could be a unigender Pokémon, but I can see it pulling off a Gardevoir and being mixed.
The colour scheme might be a little drab, I'm not sure what to do about that. I might colour the ribbons purple or something and see about that but I'd like suggestions.

This is a picture of it flying around, doing its ghostly deeds...

Here it is performing Rapid Spin, oddly enough. I realize the concept has very little to do with Rapid Spin, I just hought it looked like it could use it. x) Maybe Whirlwind instead?
