crossovers

galorechallenge is a returning Crossover Fic Challenge from LiveJournal where you would find a crossover, grab a prompt & start writing! NO CLAIMING NESSARY! Post your story to the community (or at least link to it) once you're done. Feel free to grab more than one prompt, and more than one crossover! There are no limits on how much you can write per round. Check out the rules for more information.
Also once the round ends, we'll vote on our favorites by fandom & you can get a fancy award. Or if there is only 1 crossover for a particular fandom, it will move on to the next round.
While it is a multi-fandom challenge, and SO MANY fandoms are allowed, there are some restrictions, so check out the fandoms currently allowed.
Round 14 is open until June 30, 2026 @ 11:59 EST.

(Mods - this could use a Portal fandom tag)

This is only the second time I've started posting something novel-length with very little prewritten or even planned out in advance, and Portal is a very new fandom for me so I'm not super knowledgeable on the lore. The plan is to go for moderate to occasional heavy smut and put more emphasis on the emotions and actual story. Regular and frequent updates will likely be the exception and not the rule, but you never know what the future may hold.

Last Resort
Portal / Terminator: The Sarah Connor Chronicles / Portal 2: The Unauthorized Musical
GLaDOS, Chell, Sarah Connor, undisclosed characters
Gen, F/F
Time travel, artificial intelligence, emotional baggage, consent issues, angst and feels, angst and fluff and smut, apocalypse fix-it, enemies to lovers
Mature audiences
Word count: 2,689 words (incomplete)

Being a hyperintelligent supercomputer, it doesn't take GLaDOS long to realize she's made a mistake. The solution may involve more than trace amounts of time travel. But it's a simple plan.

What could go wrong?

Post-"You Wouldn't Know" / post-2x22 "Born To Run" with some changes to canon.

If anyone fancies joining in with this on-going ghost/vampire/murder story, please let me know.

So far, there are several original characters, plus Sam and Dean Winchester, and Lestat de Lioncourt. It's open to any character from any fandom, as the plot is totally flexible and able to be taken in any direction.

I've made another themed rec list of crossover fic - this time with the theme of crossover family.

Fandoms include The West Wing, X-Men, Buffyverse, Lucifer (TV), Daredevil (Netflix), Doctor Who, MCU, Teen Wolf, Murder She Wrote, NCIS, Dark Angel, and Smallville.

As with my previous list, I will be adding to this as I discover and/or remember more fics that fit the theme. Fics that fit more than one theme will be on more than one list.

I hope you all find something new you enjoy!

Hi! I've made a themed rec list of crossover case fics - crossovers between crime or medical procedurals and speculative fandoms, where the format and focus is on solving a case - over at my journal.

This is one of my favorite genres of crossover fic, and I'm excited to share my favorites with you all. Most of these will be on AO3, but a few are on other archives like A Teaspoon and an Open Mind, or Twisting the Hellmouth.

This list will be updated if/as I discover or remember more fic that fits the theme.

Please come take a look if you're interested!

Fandoms currently include CSI, Criminal Minds, NCIS, House, Numb3rs, Law and Order, Buffy, Supernatural, Highlander, Dark Angel, X-Men, Batman, Doctor Who, Torchwood, The Sandman, The Sentinel, Lucifer, Teen Wolf, and Murder She Wrote.

The Halloween season is the time for recs! Fics, vids, graphics, anything and everything fandom has produced in all the Whedon fandoms will be on offer

buffyversetop5. We'll be reopening on October 20 at midnight UTC (what time is that for me?) and running through midnight November 2.

I'm SO excited to work a brief 2-part Lucifer cameo into my SPN/TWD crossover!

I feel like their addition is a stand-alone storyline, so if you're a Lucifer fan but don't want to read the whole longfic, check out Ch. 27.

Mods - is there any way I could get Being Human (US) & Lucifer tags? Thanks so much!

Title: What We Become: A Supernatural/Walking Dead Crossover

Author: Ahavah

Genre: Apocalyptic, Horror, Action/Adventure, Supernatural

Rating: Mature

Warnings: Graphic depictions of violence and gore, major and minor character deaths, adult language, longfic, WIP

Spoilers: Spoilers for both series, as well as mild spoilers for later seasons of Being Human (US) & Lucifer (tv), whose characters have cameo storylines. I hope you won't know spoilers from what I've made up or swapped around.

Summary: Fic: Set after TWD season 3 (after Woodbury but before Season 4 picks up) and an alternate SPN season 6 where the main apocalypse was still thwarted but Pestilence succeeded in releasing the Croatoan virus "swine flu vaccine".

Chapter: 27: Morning Star After the group parts ways, the Winchesters investigate an angelic anomaly. Featuring a cameo from the characters of the Lucifer tv show.
