Summary
Sans didn't expect to find the door to the ruins open. He didn't expect to find a human corpse, piles of dust, and a lone living human baby inside. He sure has hell didn't expect ending up taking care of it. What does he know about babies, anyway?
But a promise is a promise and this one has to be kept.
No matter what.

Summary
With no memories and nowhere to go, you’ve been shuffled from universe to universe as the secret healer of the guardian of positivity for a decade. But years without a place to truly call home would leave anyone a little stir-crazy. So when you find a knife-wielding skeleton in the woods on your morning jog, you go against your better judgement and heal him. At least he’s nice enough to pay you back with outings that are starting to feel a whole lot like dates.
Too bad that skeleton is actually one of the enemies you’re supposed to be fighting against, and your existence is about to become not-so-secret to his boss.

Summary
In the end, the lost lackey wasn’t hard to find. He was sitting at the bottom of one of the shallower craters, head firmly pressed against his knees. His arms were wrapped tightly around his skull, pushing it down even further. He was wound up so tight that his knees must have been digging into his eye socket. Didn’t that hurt? That couldn’t be comfortable…
With an ounce of concern for the murderer left stranded in his AU now mixed in with the apprehension for everyone else’s safety, Outer slowly approached him.
“Heya pal” he greeted, still a good distance away. He was ready to dodge and fight if needed, but the main reason why he spoke up so early was to avoid spooking the guy. He already looked tense enough as was, and Outer was trying his best not to be a dick.
Despite his best efforts, Goopy Sockets still sprung up, knife in hand, and teeth twisted into a snarl. Outer was almost surprised he wasn’t growling at him.
He went to raise his hands placatingly, but the guy immediately lunged forward.

Outer finds Killer after he's been abandoned in Outertale by Nightmare. Will he gain a new pal, or will he end up as a pile of dust?

Summary
The cab's door closed with a soft *thud*.
Cross looked at the rear-view mirror, more professional than fully turning around to see the person he'd be driving around. He was just that, professional.
Or at least he tried to be, he hadn't been working as a taxi driver for very long, actually, but it was a nice enough job. The pay was good, even if the company that hired him was less than desirable. He'd climb his way up from there in due time.
Besides, the service was plenty when the city was so full of life.
Not this part, specifically. This part was nearly desolate, industrial estate thirty minutes away from it, no one in sight... except for the man that he had in his back seat.
Or,
Cross is an overworked taxi driver, too overworked to really judge the weird guy that keeps on requesting rides from random location to random location. He pays well, and Cross really just wants to get by. He knows nothing of the other, other than how nice he is to talk to, in the sea of tourists he has to drive around.

Summary
Annoyance and guilt is a tumultuous concoction that roils in his nonexistent gut and combusts outward into a vexed growl before he could stop it. He tried to hide his limp wings further but they laid, broken and useless just like him, tucked into his sides from where his draconic bottom half sat. “I already told you and Chara both, they’ll heal on their own.”
“I know,” Epic soothed. “I won’t try an’ heal them. I just wanted to clean ‘em a bit, that’s all.” Epic’s smile falls at the corners as he gazes purposefully over his body. The inspection has Cross defensively straightening his back and feathers bristling before he can think of why he’d do that.
“Figured you probably weren’t feeling too great after not showering for a hot minute.”
With dawning horror and shame, Cross realizes he hadn’t exactly been able to bathe after…everything. Shit, he hopes he doesn’t smell that bad after a month.
When Epic’s turned back around to fiddle with his machinery, Cross takes a quick sniff under his left humerus and winces. Nope, he smelled that bad.

Kiss (me now) and Tell (me you want me) by ChocoholicLogophile

Summary
“I’m sorry?”
Magic rushed to his own cheekbones as he repeated, “Could you teach me how to kiss?” His soul beat faster in his chest.
Epic’s mouth opened and closed as Cross watched in real time as the gears shifted in his mind, replaying and processing his inquiry and confirming as his eyelights darted over his face that he was serious. It was rare to catch Epic off-guard, his friend usually unflappable and down for anything that was all in good fun.
Epic’s startled blush lightened as his flustered expression settled into something more contemplative. Bemused, he asked, “Why, uh, why?”

Summary
Dream wasn't expecting to find Error when he located the negativity source. He definitely didn't expect to find the so called Destroyer curled up on the ground, glitching horribly and unresponsive.
Error doesn't understand why an anomaly is so willing to help him. But something about Dream ends up making his soul flutter as they continue to spend time together.
Perhaps positivity and destruction can get along, even with the struggles that come with it...

Summary
Hopping from universe to universe after his own Anti-Void no longer suffices as a safe place from the chains of Fate, Error winds up in Nightmare’s Castle with none other than the God of Negativity himself, who’s far too pleased with the Destroyer’s presence. Unaware of Nightmare’s true intentions, Error finds himself taken aback by a suspicious yet remarkable deal that very few people have the courage to propose.
It was meant to be a simple session, a once-in-a-lifetime opportunity, but then the both of them find out that there might be more to their meeting than meets the eye…

Summary
Error blinked in surprise, staring up at a rather puffy-looking Sans.
He was sweating, his eye light spilling red magic into the air as he stomped into the clearing. There was no doubt that this was the Sans of Underfell; otherwise known as Fell among other Sanses.
For a moment he wondered if Fell had noticed him or not.Bookmarked by AFlyingManta

Summary
In which all the bad Sanses, and especially Nightmare, learn that Nightmare's corruption seems to have a mind of its own.
A mind that has, apparently, decided all his lovers were important to him and therefore deserved to be protected and helped at their lowest points. Who knew ancient corrupted emotion magic would be so much better than therapy?

Summary
Five years after Frisk freed the monsters, the multiverse began to collapse — merging every version of the Underground into one fragile, uneasy peace.
The Sanses and Papyruses of those worlds have learned to coexist. All except one.
The original Sans keeps his distance, isolated and withdrawn, haunted by something no one talks about — least of all his brother.
When Underfell Sans (“Red”) loses a drunken bet, he’s forced to ask the other Sans on a “date.” What starts as a joke turns into something much more complicated. The quiet, nervous skeleton he meets isn’t cruel or bitter — he’s broken, polite to a fault, terrified of making anyone angry.
Red can’t stop thinking about him. About what could make someone so kind so afraid. And about why Sans flinches every time his brother’s name comes up.
As Red digs deeper, the truth he uncovers will test every assumption he’s ever made about family, love, and the kind of monsters they’ve all become.
Themes: Trauma recovery, found family, abuse and healing, love as redemption, identity across multiverses, breaking cycles of violence.

Summary
Nightmare's life is great. He's one of the most powerful threats in the multiverse, despite the Star Sanses' (often failed) attempts to stop him. He destroys AU's on a weekly basis, feeding on their negative energy. And when he's not out causing chaos, he's at home either taking care of paperwork or taking care of his four boys. Nightmare has everything. A home. A purpose. A family.
He should be happy.
But he's not.
He can't be. At least, not until his brother pays for what he did to Nightmare all those centuries ago. The only thing standing in the way of his revenge is Dream’s positive magic. Thanks to some help from a potion Sci made, Nightmare can finally fix that pesky little problem.
Unfortunately, that problem isn’t the only thing that’s little now.

Summary
After an incident at the world-famous Ebott Aquarium, you find yourself placed on a team of staff dedicated to the care of the prize exhibits at the facility; three notoriously aggressive skeleton siren monsters captured in the name of 'research'. An orca with a disturbing record of finding new ways to attempt to drown his keepers, a shark who's excellent at removing whatever stray hands come his way, and a deep-sea octopus whose past (and body count) are hidden behind endless stacks of legal papers. Despite their pattern of brutally murdering their ever-changing team of keepers, they all seem to immediately take a shine to you- a worryingly bright shine. A shine that won't go away, a shine that starts to unnerve you.
However, the longer you work there, the more you see the inner workings of Ebott Aquarium. The more you realise the sirens you're 'caring for' aren't dumb beasts, they're deeply intelligent... they aren't mindlessly aggressive, they've gone insane, locked in those tiny glass cages.
... The more you interact with the sirens... the more you realise their murderous aggression might not be all that misplaced.

Summary
Running from your past isn't so simple when it's actively trying to catch up with you. Cross never had a simple life, no luxury, rare instances of happiness. When he finally breaks free, he's willing to do whatever it takes to stay out of the chains of a puppeteer.
An Underverse fic where Cross is in hiding from XGaster and gets taken into Nightmare's gang.
(The tags make it seem more horny than it is, it is horny in places but it's a more serious fic about morality and difficult emotions.)NOTE: Cross is not sharing a body with Chara in this fic.
