User blog:Martialmaniac/Characters whose Nen type was revealed elsewhere

Do you think we should create a category for those characters whose Nen type was not revealed in the manga, but in another medium (such as the cards)? And if we do, should we also include Nen types from the databook, make a separate category for them, or none at all?

Apologies for the clumsy phrasing, my language skills are defunct.
