Comic books would be under "Sequential Art & Animation" in this scheme. "Sequential Art & Animation" would cover comic books/graphic novels, web comics, manga, manhua, anime, comic strips, cartoons, etc. If the category is enormous, we can always create subcategories, but the goal is not to use fandom terms, but generic format descriptions.

Bandom goes under Music_RPF. The existing subcategories under Real People -- Music RPF, Sports_RPF, Actor_RPF, and Historical_RPF -- would remain where they are now.
I think the SCA would fit under Fandoms by Community.
