It ranks a good bit higher than Vulpix... I never really thought of them as similar. I can't really explain it, I like Shinx's type better and his coloration. Somehow it seems less girly than Vulpix to me. The thought of it having intimidate is also pretty hilarious. I don't have any anime or KFC memories to draw upon, so maybe Vulpix was spoiled for me a while ago. I don't want to say much more since Luxray hasn't been revealed.
