We don't need a category for "Royalty". As for "Voltron Alliance", I see the merit in it, but think they only use "Voltron Coalition" for the rebellion against the Empire and the term "Alliance" is used in one episode of S1 and then never used again. (I watched S7 only once through tho so idr if it's used there.) I'd wait until the end of the series to see what they eventually call the whole "good guy" group of the universe once all the remaining villains are dealt with. Because categories can't be renamed, you have to manually delete the old, make a new, and then remove/add categories to pages, so waiting means less work. And also check if such a group doesn't exist in other Voltron series in case a distinction needs to be made?
