The Bulbapedia Article hits the nail. But if Game Freak decides to make all Fairy-type Pokémon with feminine and cutesy qualities, then this is all moot.
Saw this as an ad next to a YouTube Pokémon video... these Dragons of Atlantis people aren't fooling us!
Just look that Gible, he's leaving all in the scene.
On the other hand, I hope they make an enchanted suit of armor that's Steel/Fairy type. I would use that as a dragon slayer.
