Summary
Created by a laboratory along with other Monsters, (Y/n) or as she used to be known SKE-7, has been on the run most of her life from the shady group simply called 'The Company' that sought to use Artificial Monsters as tools or weapons. She lived in hiding with the scientist who made her and his son for years when suddenly Monsters came to the surface from under Mount Ebott, not long after Monster experimentation was declared illegal finally giving (Y/n) the chance to live out in the open and achieve her dream of being a Chef. Sadly Skeleton Monsters are quite rare, but just as she thought she'd be the last of her kind she runs into some unexpected, or we should say a skele-ton of surprises! Our Skelly is free at last to enjoy her life...but are there trials ahead?

Summary
“Shh, sweetling,” Sol whispered, his voice a low murmur against the curve of Dream’s acoustic meatus. The tone was silk spun with thorns, indulgent and unapologetically crude. “You’re so pliant like this. Did you know that? Such a pretty thing, even when you’re trembling.”
Dream’s SOUL hammered against his ribcage, a wild, frantic rhythm that echoed in his skull. He tried to speak, to protest, but the words caught in his faux-throat, swallowed by the haze of his mortification and the lingering pull of sleep.

Summary
Reader is an exhausted retail worker with nothing in life to look forward to but finishing her shifts daily, coming home, and playing her new RPG VR dating sims game called The Skeletons’ Castle.
She knew she was probably weird for preferring a monster romance simulator over the ones with the usual ‘hot’ anime male options, but it had just the perfect amount of horror and mature themes she was looking for.
One particularly hard day in her life, reader turns to her game to escape, this time restarting a save file after a particularly brutal ending that leaves her disappointed. What she doesn’t realize, is this is her last and final play through, because she gets transported into the game as a random side character, not even as the main character! And now she can’t exit!
How will she survive this intense game, or rather, her new reality?

Summary
This takes place in a post Underfell King Papyrus ending.
Struck by under population, King Papyrus makes it law that all monsters left alive by the murderous little human have to procreate. This leaves Fell!Sans and The King himself in a tight spot. There are no female skeletons left in the whole Underground and both skeletons are sure they are the last of their species. Fell!Sans proposes something. With the help of the first Royal Scientist's machine to travel to other universes, he will find mates for breeding purposes.
Tale!Sans is having his first sub heat as a female. This happens when there are only males left and the strongest one undergoes a gender swap. He knows this means Papyrus will have to be his mate.
That won't do. They are brothers, for the Angel's sake! So he does what he does best, HE RUNS.

Summary
It’s then that Palette really gets to see what Nightmare looks like. Feels the slime covering every inch of bone, oily and dark, the one eye socket forever covered, the other a striking cyan glowing starkly in the darkness.
“Don’t tell me...”
Palette swallows hard, the weight of his dad’s warnings pressing down on him again. Never tell. Never let him know. His dad’s voice in his head is loud, desperate. Nightmare couldn’t know who he really was. It wasn’t safe. For him. For his dad. For anyone.
But Nightmare’s grin returned, wide and gleeful. “Dream had a child?”
