We've just happened to see dragons who have elements. We've seen dragons with a null element: Motherglare, Zirconis, Scissor Runner, and the Dark Dragon. They just run absolutely loose and destroy stuff. I mean, Zirconis was named for his color; Belserion was named for his wisdom. Dragonic naming conventions don't appear to necessarily follow elemental or eating standards.
