Summary
Onto glitchy, uneven ground they fell, looking up at the sky that wouldn’t last. The sky looked abnormally bright, with the earth itself sputtering beneath their limp body. They reached forward, grumbling before rising up with a stumble, wobbling over to the cliff as they dust themself off. They stared down at the bottom of it, frowning. It was so high up, yet they.. didn’t want to really take a step back.
The sound of a soft crack entered their ears, yet they continued to blankly stare down, before their gaze met the town just beside MT. Ebott. Another crack, yet they just relished in the view. One final crack, and they begin to stumble downwards. They pay it no mind considering their earlier fall.
What they do pay mind to however, was a large piece of the cliff cracking, falling off and bringing them down with it.
OR
How a glitchy, traumatised Frisk (and Chara) met Error and Nightmare, and how that caused them to meet the Bad Sanses.

Summary
You were quiet for a long moment. “i’m supposed to be dead,” you told the skeleton.
“… you’re not,” he replied, after pausing for only a second. “there’s no supposed-to with you. you were in the anti-void, not an au. you nearly died, but i fixed you.” His voice was quieter than before, and his head was slightly tilted, like a curious dog. “i don’t normally bother to do that.”
“then why did you?” The words hurt in your mouth instead of your throat. It felt like carbonation below your tongue, and it took concentration to keep that static from leaking into your words. You weren’t used to talking. But this was important.
“why’d i fix you?” The skeleton paused, expression going blank for half a second, gaze flitting down to his scarf. “oh!”
The corners of his mouth tugged up again. “because i want a little brother of my own, of course!”

You used to be human, before what you called the Blank. You were a teenager, and you liked dogs and the sun and couldn’t remember much more than that. Then you were made into something else.
After your rescue, you try to adjust to living again - and attempt to understand why so many weird skeletons keep trying to adopt you.

Summary
Sans stays silent. He has to, because his brother is right. He is a hypocrite. But he has to be. If he wasn’t, he doesn’t know how he’d live with all he’s done. He wished he was never born. But he never gets what he wants, does he?
A piercing shout rings through his skull as Papyrus is suddenly in his face. “You are scum! Filth! You have disgraced the Underground, and you have failed me! You don’t deserve to be called my brother, you bastard!”
--------
Replay's early days in the Anti-Void. He is not a fan.

The Forsaken and the Cherished by stitchthelilo for thovcs
Fandoms: Forsaken (Roblox), Undertale (Video Game), but not a crossover kinda situation

Summary
Seven was confused.
Seven was really confused.
As the Destroyer of Creation, he had a very important job to do every day; keep the balance of the Multiverse, and make sure there were never too many AUs being made. He used to love the job, as it fulfilled his sadistic pleasures - but even now, despite those same looks of fear, he saw it more as a chore than a way to vent out his frustration and violent urges. After a couple centuries of doing the same thing, anyone could get tired of it. He never allowed himself to feel bad, though. Emotions were bad for the job.
But, because he was the Destroyer of Creation, Seven always looked out for AUs to destroy. Sometimes he came across empty AUs, but he never paid any attention to them because there were never any residents.
This time, there was.
OR
When the Destroyer of Creation - Seven - discovers across a lost child in a blank AU, he’s forced to take him in and raise him as his own. Sometimes, he feels as if this is how things were always meant to go.
Only problem is.. he lacks any code.
P.S; This is not a traditional crossover fic, this is a fic where 007n7 is in the role of Error Sans, and Chance is in the role of Ink Sans.

System Error: Accidental Acquisition of Children by Frikisbits231
Fandoms: Undertale (Video Game)
05 Sep 2025

Summary
Error slid down, glued to the tree, his back to the ground, into the lush green grass on the ground. Later, he'd take a look at his current situation and possibly eliminate the place without a problem. Meanwhile, Error was resting, leaning against this comfortable, curvy tree, closing his eyes to feel something, something of the place.
Feel... the familiar ambient magic?
Still no monsters, humans, or standard souls around. Well, no one could hurt him if he got some rest, right?
This time, he mentally prepared himself and repeated the safety tests he felt like a mantra so he could get some rest.
He fell asleep shortly after.
…
Sweetness with hints of security, calm, and the tranquility of dawning rest captured his senses. Something... familiar. Like... like chocolate melting on his tongue. He didn't know how he recognized that either. Still, he pulled the tongue out of his space, to capture it. He caught the sensations, almost becoming overwhelmed by them.
(O: The one where Error acquires an abandoned baby bone, which is, of course, his offspring too, yay...)

Summary
"Limerence is characterized by an intense and persistent obsession with another person, accompanied by fantasies, longings, and a strong emotional dependency." Someone inhaled sharply upon hearing the goddess's wise words. Respectfully, no one looked in the direction of the King of the Heavens.
"A person in limerence might not want to feel that way," the goddess of wisdom, Alphys, continued, moving on to another sentence that definitely caught Nightmare's attention. "Perhaps the target of limerence isn't even her type. But there's something about that person that attracts and triggers her," she concluded.
After a minute of silence, Negativity decided to break the tension.
"...You know, I wish I'd known about this, before all of you jumped to conclusions with Death, and got me involved in that whole immortal mess." Nightmare sighed, closing his eyes to avoid the embarrassment the entire Pantheon of gods must be feeling as they looked at them. "Honestly, you..."
"You have no right to separate me from my chosen one, my mate." Death growled, causing a blush to appear on said mate's face.

Kiss Me, Kill Me (And a Secret Third Option) by Embrace_the_Deep (DefinitelyNotABee)
Fandoms: Undertale (Video Game)
28 Jul 2025
Tags
Summary
What had Ink tried calling him again?
Someone named Killer?
As fitting as that name would have been for the previous owner of his body, he clearly remembered that he had been referred to as 'Sans' in the blurred bits of memories.
Maybe he was being mistaken for someone else.
He hopes he never meets this actual 'Killer', but even if they were some sort of shady person- skeleton- thing, that doesn't excuse kidnapping a stranger and chaining them to the floor of your home after nearly killing them!
With the most unimpressed expression he could muster, Quill forced the aching phalanges of his right hand into a wrist-up fist, and extended his middle finger.i.e. A self-indulgent crack-treated-seriously fic featuring isekai!Killer vs. the Multiverse. Enjoy!

Error is pregnant with Dream's child, excited to have their firstborn. They're close to the due date, we'll see what happens next;)
Did I say Dreamerror and then that PJ was born? Yes, I did. Me and my friend were brainstorming ideas for the plot and they came up with Dreamerror. I wrote this at 4am and didn't realize until later that it didn't make sense but was way too tired to change it into Ink.

Somebody That I Used To Know by Ice_Hunter
Fandoms: Undertale (Video Game), Sans AUs - Fandom
02 Jun 2025
Tags
Summary
“You want to break up the Star Sanses?” Blue repeated what Dream had said in shock, standing up from his seat suddenly as if he wanted to argue with him, “Dream, this isn’t a good idea! You can’t fight Nightmare alone, he’ll destroy you. There’s too much negativity, you said so yourself yesterday, and it makes you weak..."
-----+-----
Ink had done it for the last time. Dream couldn’t stand him sacrificing so many people to save the AUs that made up the multiverse, he couldn’t stand Ink making the Star Sanses be seen in such a bad light that Dream was getting sent death threats. So he broke the group up, even with Blue’s protests and Ink’s surprise. The Star Sanses didn’t exist anymore. He wasn’t Ink’s friend anymore. Blue couldn’t multiversal travel anymore, stuck in the Omega Timeline since he couldn’t go back to his AU. Dream didn’t have people to back him up anymore. And with no group seemingly able to stop people who meant harm and protect AUs anymore… There was a spike in destruction and negativity. The negativity was because of Nightmare, but what was destroying harmless AUs? That was what Dream was going to figure out. Who knew he’d meet someone special to him in the process?
