Defining major character by media is not a good idea in my opinion, because then we wouldn't have pages like Bertilak Celadon who is only a book character, but has a describable appearance, name, and actively participates in the books as a major antagonist. The only thing he doesn't have is a voice actor.

Following that, sorting by Kingdom they were seen in sounds best to me.
