Deleted Coldflash fics

Hi, Coldflash fam!

For the past month, I’ve been working on a fun little project to recover as many fics that were deleted from the tag as possible. I’ve managed to find quite a few of them (some I never even knew existed), and I will happily share them with anyone who is interested, but there are also many I haven’t been able to recover yet, so I thought I might as well try asking tumblr for help!

Here’s the Dropbox link with the full list of deleted Coldflash fics I’ve been able to identify.

Please send me an ask or message me if:

you’ve kept a copy of one of the missing fics and you’d be willing to share it

you can think of some deleted Coldflash fics that are NOT on the list (even if you don’t currently own a copy of them)

you’d like a copy of one or more of the deleted fics that I did manage to find

I’ve considered making a zip folder or public OneDrive or something where everyone has access to them, but there are several problems that have kept me from doing so quite yet

If you want a more detailed explanation, I will ramble about that below

The main problem is that most of these fics were originally saved in different formats. Some of them are .epubs, some are .pdfs, some are .txt files, and a few still only exist on the Internet Archive, as I haven’t gotten around to making a copy of them.

In order to share them, I’d have to convert them all to the same format, for ease of use and because I’d like the drive to be at least a little organized!

I also wasn’t sure if anybody would even be interested in this idea and which format they would prefer if they are. Please note that a lot of these fics were unfinished, some are just drabbles and some only have one chapter. I was interested in retrieving them for archiving purposes, but I’m not entirely certain they’ll necessarily all be of equal interest to anyone else…

So, basically, let me know what you’re thinking, whether you would like me to create a public drive or not, and which format you’d prefer if I do!

In the meantime, definitely send an ask or a DM my way if you see a deleted fic on the list that you’d like a copy of and I’ll get back to you ASAP

I wondered if there were any fics that cover infinite-crisis with Coldflash? No worries if not!

There are a handful of fics that are post-Crisis, but I can’t think of one that’s actually happening during the Crisis, sorry.

[coldflashficlibrary]

Heyy I remember this really weird fic and I honestly don't know if it exists but it's one where Barry was captured by some rich collector along with other metahumans I think

Len is looking for him or helps team Flash look for him and the next chapters is Barry recovering from the trauma I think?

Hi! That sound like it could be To Pretend this Never Happened by RedHead.

[coldflashficlibrary]

Hi do you know any fics where Barry gets like really into meta-human rights (like I swear there was one where when he was trapped in the mirror by mirror master he and Julian argued about it or something and it was being recorded and went viral and he was elected and some sort of meta-human spokesperson but I can’t find it) preferably coldflash but it doesn’t have to be thank you

Hi! The fic you’re looking for is Going Rogue by nlpiersee

I can only think of a few other fics that deal with Barry getting involved in some way with metahuman rights and meta discrimination:

Remembrance by Onyx_Stars

Falling Fast by HolyCafe

A Fine Day for a Forced Wedding by Alexis_Tenshi

I Live So That I Will Never Die by sweetNsimple (this has some supernatural elements, so not sure if it will be what you’re looking for)

By Any Other Name by cardinalstar (unfinished, sadly, but it is 250k so I’m including it anyway)

I don’t save anything that’s not Coldflash so I can’t really help you with more general Flash fics. But if anyone else can think of fics to recommend to anon, please say so in the comments!

[coldflash-ao3feed]

Welcome!

This is an automated AO3 feed who posts from the Barry Allen/Leonard Snart tag on AO3. It is a successor blog for @ao3feed-coldflash which hasn't been active since 2022.

It only generates posts for new stories; additional chapters are not posted. You'll need to subscribe directly to the story on AO3 for that.

If you have restricted your work so that only logged in AO3 users can access it, it will not be picked up by the automated feed.

You may send an ask with a link to your restricted work if you want me to make a new post for it in the feed style here.

Ask box is open if you run into any issues!

[coldflashficlibrary]

Do you know if there are any good works with Barry aiding the Legends? Coldflash established or otherwise.

Thanks!

Hi! Here are the ones I could think of:

We Could Keep Things Just the Same by asexual-fandom-queen

Taking Our Chances by BeauxregardsTaxicab

The Mandretti Affair by Moriavis

real by dryadfiona

The Time Beast by Writing_Queen

what the future holds by avengersincamphalfbloodstardis

If anybody can think of more, don’t hesitate to say so in the comments!

Hi! Here are some fics that might fit the bill:

my eyes caught light from yours by Moriavis

Ace of Hearts by haute_coldture

A Walking Bad Decision by Triskel_Samulet

[irresistible] by MissSugarPlum

Smooth Criminal by FableOfUs

The 2026 Coldflash Fic Exchange is Live!

An Archive of Our Own, a project of the Organization for Transformative Works

[coldflashficlibrary]

Hi!!! I’ve been watching the Flash series and I love it and I also have been hankering for some coldflash… I read and loved Tumbling Together and that’s about all I’ve read so far, do you have any longfic recs, preferably no mpreg (although I don’t mind it much) but lots of hurt/comfort? I love shenanagains and angst alike and would prefer fics that are in-world (Barry di the flash and Len is cap cold) Im fine with soulmates! I just need to devour some stuff and I haven’t been having a ton of luck searching. Thank you so much!!!!!!

Hi! Here are some longfic recs for you:

the roommate verse by coldflasher

It truly does not get longer than that! It starts with Len and Barry becoming roommates and getting together pre-series and then expands into a giant 600k S1 re-write, with Barry becoming the Flash and Len becoming Captain Cold, and both of them hiding it from each other.

Seventy Three Seconds by RedHead

This is from the same author as Tumbling Together, and I would definitely recommend checking all of their other stuff out! Their soulmate AU is also very long and it’s probably the blueprint for soulmate AUs for this pairing. VERY angsty though!

Out Cold by Crimson1

This author has written some of my favorite Coldflash fics, so if you like this one you might also want to check out The Color of Love, Lovesick and Timeless as well.

This Delicate Thing We’ve Made by spacemonkey766

This is a slightly more recent one, from 2020, and it was posted all at once so I feel like it did not have time to build as big an audience as it could have, but it’s great! This is post-Oculus, so the Flash/Cold dynamic is a bit different than in earlier ones, but no less compelling imo.

Landslide by Maxc

Okay, so this is a Sentinel/Guard AU, so might not be what you’re looking for, but Barry is still the Flash and Len is still Captain Cold, so it’s not totally removed from canon. This is kind of the wild card of this list though, so feel free to take it or leave it!

The Things series by n_a_feathers

A classic for hurt/comfort fics if you ask me! The series is 4 parts and complete, and although some of those parts are pretty short the whole thing is still decently long (150k words in total).

The Second Time Around by Linzero

I’m cheating a little with this series, because it’s not done being posted (it is still being updated though), but the first two parts are complete and it is already over 330k, so it might still keep you occupied for a while.

If anyone else has longfic recs for OP, please don’t hesitate to say so in the comments!

[coldflashficlibrary]

Small update: I’ve added the summary, chapter count and word count for every deleted fic I currently have, because I think it will make it easier to navigate for anyone looking for a specific deleted work.

[coldflashficlibrary]

Let me know if you want me to upload them somewhere for you since AO3 is down rn

[coldflashficlibrary]

I can't believe it's nearly the end of January! I have too much to do for the year to be going so fast already.

@coldflasher and I are going to discuss what Coldflash events we're going to have this year, but I definitely want to hold the Fic Exchange again, it was so fun!

An Archive of Our Own, a project of the Organization for Transformative Works

Here are the dates and rules for the Exchange.

I've also opened the sign ups early!

We will keep you up to date on what other events we're going to have as soon as we know! <3

[coldflashevents]

Sign-ups are open until March 1st, FYI!

[coldflashficlibrary]

Library, I am lost and have forgotten. I am trying to find a Coldflash fic that I read years ago. Barry gets whammied by Bivolo to be in love with Leonard. Leonard has to navigate Barry’s attachment to him as well as his own feelings. I remember Barry’s pupils turning into little hearts when the effect was particularly strong.

It’s multi-chapter, but it’s not Drunk Minds Speak Sober Hearts by m4x_87 (which I already reread today).

Hi! I think the fic you’re looking for is Love Me by sinplicity.

[coldflashevents]

Greetings, fellow Coldflash lovers!

@moriavis and myself (@coldflasher) have been at work behind the scenes deciding on this year's event schedule, and we are pleased to announce our first event of the year:

Coldflash Valentine's Day Weekend 2026!

This event will be held from the 14th to the 15th of February.

The theme is romance, whatever that means to you. We're keeping this one nice and flexible, so there are no prompts or word limits—and you can feel free to get creative.

As always, all fanworks are welcome, not just fanfics. Playlists, moodboards, edits, art, all are encouraged.

We'll be sharing some more details on our other upcoming events soon, so watch this space!

Feel free to drop us an ask if you have any questions.

Happy Coldflashing!
