Tag horse
Something else to consider that there isn’t much representation of in your examples are Dullahans and other, modular/magical/non-gory heads not screwed on right. As such, tags like “detachable head” and “detached head” do exist (and probably should be aliased with each other) and the question really is, are these the tags to keep mutually exclusive? I would say that “severed head” and “detached head” definitely should…but “decapitation” is debatable. After all, it is possible to see a dullahan with the head put on, in which case it would not be “detached,” but when they take the head off - what tag do we use for that?
Some dullahans:
(one gory-ish dullahan, just to be contrary)
