Unfortunately, you picked the only member of the x-men who turned out to be a goddess and not a mutant (can't remember what story arc). How disturbing.

Replying to a very old comment, but doing so to note that although Storm was worshipped as a goddess by an African tribe I don't think she was ever a goddess herself (although some people do sometimes refer to as such). However, Storm's mother in the main Marvel Comics setting is a powerful sorceress, and I think that there's some canon evidence that Storm inherited some of that ability.
