I think you do a lot of good work adding missing categories to articles in general. :) Since you've been doing a lot of category-related editing, I thought I should share some notes with you.

I noticed you kept misapplying Category:Martial Arts to character articles. So, with this confusion in mind, I recently created Category:Martial Artists. Martial artist characters can go there, but Category:Ninja is a subcategory and ninja should go there instead. The S has informed me that Category:Ninjas should remain empty and not be used, because the wiki has formally decided to use Category:Ninja in all cases.

I also recently purged the category Non-Humans as an excessively broad category of exclusion. Ideally, non-humans should be found in the various subcategories of Category:Characters by Species where Category:Humans should also be a subcategory.

I'm trying to help reduce category clutter in general. It is best for articles to be placed and cross-referenced in appropriate and relevant subcategories. Broader categories (like Category:Mammals, Category:Reptiles, etc.) shouldn't have direct article entries unless there exists no appropriate subcategory for that article's species. For mutant species used only once (like hedgehog, aardvark, etc.), a dedicated species category is currently not necessary&mdash;a category needs at least two entries (two articles, two subcategories, or one article and one subcategory) to justify its existence.
