toothpastejuice | Rarest of Rarepairs 2025

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.
