FWIW, when I first came across categories such as Category:Batman, Category:Flash, etc I had assumed that they were for characters that had used that identity. Not that they were for everything under the sun that touch on that character.

That said, I can see an argument for them including:
 * 1) The character that use the identity.
 * 2) Series titled after the character. Or, if there are enough of them, the "Name Titles" subcategory.
 * 3) Storylines from those series or strips headlined by the character in anthology titles, either individually or under "Name Storylines"
 * 4) Villain and supporting cast categories, though I'd argue both need to be ties to the villain or cast member being using in #2 above. No, I do not think that Kal-L should be grouped in the Power Girl Supporting Cast nor Booster and Ted Kord cross categorized as the other's supporting cast.
 * 5) At the far end would be other media titles that are primarily focused on the characters under #1.
 * 6) Lastly, if subcategories for #2, #3, and/or #5, then only the subcategory should be added. Barring that, the only individual articles/pages that should be in the category would be anything under #1, #2, #3, and #5. The supporting cast/villains shouldn't be individually catted - even the dab pages - in these things.
