Summary
Disclaimers:
Several details in this fic are heavily inspired by 'Blue joins the bad sanses' comic, so go check that out
Canon innacuracies: Passive and Corrupted Nightmare are the same person, Ink is the creator and not the protector, Ink, Error, Nightmare, and Dream, are all gods, Blue, Killer, Horror, and Dust's specific au timelines were all destroyed, and i took liberties with how the void works. Also, no Cross sans will be mentioned, i don't know enough about underverse, and there will be some OC non-sans God/entity/things later on. The fic will be split into parts, each lasting nine chapters.
Schedule: Once a week, on Saturday, Sunday, or Monday, and i will post art or a reference sheet with every chapter. Trigger warnings will be specified in chapter notes. I've never written for undertale before, so please let me know what you guys think :3With that said, the actual plot: After an injured Error crashes into Nightmare and Co's home, a close bond starts to form between the two gods, both forced villains. In light of Ink's attempt to kill Error, Dream finally starts to lose it, and Blue gets dragged along.
Average chapter length is 500-2000

A Strange Family include... by LittleNinjaSpy
Fandoms: Harry Potter - J. K. Rowling, Undertale (Video Game)

Summary
A strange family includes: at least four skeletons, a corrupted god and a human toddler.
When Nightmare saw baby Harry being left on the Dursley's porch while he was taking a stroll (read: scaring random people for fun), he was intrigued and disgusted that someone could leave a child like that. But when he got closer, he was surprised and worried—really worried. The child was surrounded by foreign magic and much more than what could be considered normal. So he took him; what could go wrong?

Summary
The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.
Within this realm, Dreamtale exists as an enigma, plucked from another Multiverse entirely. The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.
Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.
Nightmare woke up freshly dead.
Au: Get it? Cuzhe died lmao

Where Have You Buried All Your Children? by Estel_dreamer

Summary
Ink was familiar with creating, it’s what he was created to do after all. It was woven into his very magic and essence. Every universe, every variant derived from him in some way, whether it be from being formed by his own hands or splitting off from his own creation into something new. But even so, they were never truly his own. He gave them tangibility, but they gave themselves form, they took his starting point and rushed headlong into the unknown. He loved them all the same, as fleeting as they were.
Ink knew he shouldn’t have done it. He was putting more than just himself and this new universe at stake. But he wanted something that he could call his own, he wanted to be selfish and greedy just this once. He’d seen others have children, have beings tied so closely to themselves that they loved and called their own. He wanted that, he wanted his own child, his own creation.
A choice to be selfish may be just what the multiverse needs though to start repairing broken bonds, to form a happy family once more. Or it might break it all apart once and for all. Only time will tell

Summary
Error gets stuck when reaching through a hole for chocolate during a supply run and Nightmare appears before he can get himself out.
The hand trailed lower, and the glitch stilled, eyes going wide as phalanges played with his waistband under his coat. His Soul pounded in his chest, and suddenly Error found himself hyperaware of how vulnerable he was. "WhaT—?"
"Come on, think about it, darling. The poor defenseless maiden gets trapped and the big bad wolf comes along to take advantage."
"I-I'M Not A DeFEnSLess 'MaiDEn'!" He immediately sputtered, but that didn't stop his cheeks from turning bright gold as the idea was planted, "An-And DoN'T CaLL Y0uRSelF A WolF! ThAT's FuCKinG GrOss!"
Error squeezed his eyes shut, shaking his skull and trying to get the thought out of his head. Stars, he didn't like the implication there! He didn't want to think about it! And yet he couldn't help imagining what it would be like if the scenario played out— the position he was in, the teasing, the predatory gaze boring into him…
The glitch swallowed nervously, the heat spreading further across his face.

Summary
Nightmare was in the middle of speaking to the murder trio when he felt it, the distinct feeling of despair that was overwhelming. It was something he had felt before ending up with the three of his cohorts- wards- no, the better phrasing these days would be 'his boys'. He was the oldest by a few hundred years, and they were like children, but in adult form.
Anyway, it was that exact feeling that had drawn him to each of them, with Killer it was despair mixed with overwhelming guilt. With Dust, it was an emptiness that had come along, just knowing the human was no longer interested in resetting after Dust had murdered over and over, letting him drown in it. With Horror it had been an overwhelming hunger that had caused overwhelming food anxiety that took forever to get under control.
This- this despair was like that, but there was a sadness, a loneliness, and he could taste it more than any other form of negativity right now. It was the strongest feeling throughout the multiverse and it was calling to him, practically screaming at him.

Summary
“My ecto-o isn’t unsummoning.”
He kept his gaze firmly locked on the carpet, refusing to look the other God in the eye. The tentacle in his grasp curled around his radius and ulna, and he squeezed it.
There was an awful, crushing silence for a few moments, before his husband spoke: “…you don’t think..?”
*----*----*
After their mating cycles lined up, the "evil" Gods of Destruction and Negativity find themselves in quite the predicament. They must figure out how to balance their dangerous work with the task of ensuring their baby's development is healthy. That, and they have to ensure the Council does not find out.
No matter what, Ink cannot find out.

Summary
The rain still crashes, like crying over the funeral. The ash, the silence, the bones, the static. It all blurs.
My vision fading at the edges—
Glitches bloom like dying stars—
And I close my eye—Even in the darkness,
I still feel him beside me.
As if always be. -

Summary
The hit Reality TV show called 'Aftermath' was made after the confirmed truce of the Bad Sanses and Star Sanses but today's airing was different. Everybody's favourite star of the silly show was having her dirty laundry aired out by a random nobody after her creator practically sentenced her to death.

Maple (my character) gets played like a puppet by a parasite that was hungry and needed to feed.
