Rarest of Rarepairs 2025

[toothpastepancake]

It's back for another year!

Welcome to the Rarest of Rarepairs ficathon, a ficathon designed to get more fic for your favorite rarepairs out into the world! This one is for the ultra rare ones—-50 works or under on AO3. (This is slightly changed from last year's 65.)

AO3 Collection

Schedule: 

Prompting and Fills open: October 13, 2025
Prompting Closes: January 25, 2026

Fills will remain open after prompting closes.

Info:
-Any medium, even if it is called a ficathon. I don't really care. 
-Any rating!
-No minimum or maximum but fills must be complete.
-You may prompt RPF as long as the individuals involved are over 18.
-You don’t have to fill something to leave a prompt. The more prompts, the merrier!
-One prompt per comment, please.
-Prompts (except “any” prompts) and prompted works must be for ships with 50 fics or under on AO3 ( in the tag using English language works filtered with otp:true) (we're not taking into account other fanfiction archives for this round.)
-You may link to the fill if it is posted elsewhere. Regardless of where it is posted, please include warnings or say choose not to warn.
-If you'd like me to count your fills at the end of the event and award a badge, please post under the fills thread too.
-You may combine these with other events, as long as the other event allows it and there is no anonymous period.
-Canon couples/small fandoms absolutely welcome!

Posting Prompts:
Post the prompt in the following format: “Fandom: Ship - Prompt”
For example:
”Babylon 5: Susan/Na’toth - Undisclosed Desires”
-“Any fandom” and “any relationship” allowed and encouraged!
For example:
“Any: Any/Any - Demon AU”
”Buffy The Vampire Slayer: Any/Any - up too late”
 

Posting fills:
-Reply to the comment with either your fill under a cut or a link to your fill. 

Have fun, and let’s get the creativity flowing for your favorite underappreciated ships!

This year, there are ship-themed (haha get it) badges to award, based on elasticella 's Hotties Haunting The Narrative event! They can be seen below.

Here it is!

Sorted by fandom. Let me know if this looks okay or if anything needs changed, added, or if there are any mistakes (some prompts were formatted in a way that confused me since I wasn't familiar with the fandoms so I might be a bit mixed up on them)! I'll update this every few days but feel free to poke me if it's been a while, I probably just forgot :)

This is really helpful - thanks! I guess at this stage the links are only to the prompts and the fills will only be on AO3?

There's a thread for posting fills which doesn't have too many replies at the moment but I can definitely set up a tab for tracking fills in the same way if that would be useful! I'd be able to pull fills that aren't posted to the thread as well.
