Crossover Recs

[doranwen]

updated 2021-12-25

This post is my complete list of crossovers (as far as I've added them in my database). I will endeavor to keep it updated as new crossover fics are added to the database.

I have included one of my own fics in this post, and tagged it as a favorite, because I like to re-read it. (I only do this for some of my fics.) It is not marked as exceptionally well-written because I couldn't evaluate my own work with clarity that way, even if I particularly like the way I wrote something. It's also tagged as a WIP because I never did get to finishing it. *sheepish grin*

(Icons come from the Icon pack by Icons8.)

As always with my db-generated lists, ratings are all converted to a single system for convenience:
Fanfiction.net - G through R
AO3 - PG through X (though the occasional child-friendly fic I mark G)
anything without a rating (AO3 or other site) - Unrated


I have tried not to spoil readers too much.
Most of the fics in this list are given with no information beyond author, title, rating, word count, major ships, and the summary the author gave it.
However, my database does store information on themes, which cover everything from grammatical things like tense & person (I mark for present tense, first person, second person, and direct address), to format (poetry, songfic, 5+1, etc.), trope (fake couple, stranded together, etc.), general feel (angst, fluff, etc.), and warnings (major character death, non-con, violence/wounds, etc.).
If you would like to see the themes for the recs from any of the fandom lists below, please comment and let me know so I can reply with that information. It is very simple to generate the recs for a large list of fics in such a way that all of the themes are listed.
If you would rather just have a list with certain themes excluded, please also comment to let me know which one(s). You can find the full list of themes here, titled Fanfic Themes.


I listed any ships I thought were major below each fic. If there are any minor/background ships you want to avoid, please leave a comment and ask for a list to be made for you. Note that ships may refer to one-sided or unrequited ones as well as to requited/mutual.
