Crossover/Fanfic

To identify a story as a crossover, add either Category:Crossover Fanfic or Category:Mega Crossover to the Work page, as appropriate.

To identify which works are included in the crossover, add all of the relevant "fanfics by series" categories to the Work page. Yes, we know that can lead to a page with a category cloud with hundreds of entries.

If a source work has a navbox, list the fanfic there as well.
