Kitty was Sprite, Ariel and then Shadowcat but none of them really stuck, that's why when you look up "Shadowcat" on wikipedia it takes you directly to "Kitty Pryde". Again less is often more, and like "Misty Knight", "Donna Troy" sort of sounds like a code name anyway. You guys are acting as if her name is Donna Horowitz-Silberstein or something.
