Summary
“So I ask again, dear Phoenix. How bad does that scar burn?”
The long, eons long war between the angels and demons has ended decisively in the angels' favor, due to the newly appointed Angelic General, Frisk. Their strength and determination ensured a victory that was all too easy, wiping out every demon but one. One demon who was away, tricked into leaving while the angels attacked. One demon who would usually be ever too tired to think about taking revenge.
But there is only so long one can withstand the boredom of a lonesome eternity before the idea of revenge begins to sound fun.Or,
A demon Sans forces an Angel Frisk to fall. Long revenge monologue included.

Summary
A little spot for my shameless Sans x Reader oneshots and momentary inspirations to gather! Particularly, of the magical kind. Nagas, sirens, winged monstrosities, cursed creatures, fantastical beasts of all shapes and sizes... maybe even a normal skeleton once or twice, if you’re lucky! Canon is a speck in the rear-view mirror and we're all just here to have fun.
So just sit back, relax... and enjoy the mess that is me being totally self indulgent.

Summary
Kranion always knew that you were his one and only, sure you didn't know of him- only his name which was permanently etched into your right forearm. Just like how your name was permanently etched into his collar bone. His soul always knew, been watching you from afar ever since your own mark came alight. At the age of 20 (your 24 now) your own mark and his own came to your respective bodies.
The only issue? Kranion is the demonic embodiment of Glutton, and you? You're just a measly little Human.

Summary
At first, you'd had no suspicions about Red, too excited about your first summoning and space renting plans. Back then, you'd only had a soup cart and a dream. You weren't well off enough to attend the academy. That's why you didn't have anything really before your luck changed. No guild to call home. Let alone a contract.

Summary
“You... y-you did this to me. You took my wings,” she rasped, her unused voice dry and scratching at her throat, and he looked down on her a single moment longer, tail sliding over the stones inlaid around his throne with the rough scratching of a death rattle, before he shrugged, totally unbothered, and returned to his meal.
“yep.”

Summary
( This is the third book to Sans' House Guests, you should go read that and Shadows of Remorse before you read this because you will be confused on what the heck is happening! This is an original crossover story between Undertale and CreepyPasta where Sans is the main character and makes some CreepyPasta friends! I own neither UnderTale or CreepyPasta, I just own this story and crossover idea! )
17 years.
It's been 17 years since Sans had last been heard from, and his old friends and family have grown to accept that he wasn't coming back. They made their mistakes, they pushed Sans out of their lives. It was only fair that he lived his on his own accord. And if Sans didn't want Papyrus to be included in that life, then that was fair.
But it doesn't look like either have a choice when their lives clash again.

Summary
Injured and halfway frozen, (Y/N) wakes up in a snowy forest with a mental block regarding the series of events that led to her terrifying situation. She's rescued by a strange man named Sans with a lazy grin, as well as his equally strange friends who are certainly not what they seem. As (Y/N) tries to piece together what happened to her, strange and unexplainable events are occurring around her in the small town of Snowdin, and they may have more of a connection to Sans and his friends than (Y/N) can possibly imagine. And even if it scares her, they're the only ones who can protect her from the increasingly sinister things that are plaguing the town.

Summary
During the war known as The Schism, Angels forced Devils to the Rings of the Underground in an attempt to save Humans from Vice. However, Humans still practice Vice, causing Angels to have animosity towards Devils. This leads Angels to kill Devils on sight whenever they attempt to come to the Surface.
Red is sent by his brother Fell to destroy a Devil that has been sighted around Limbo, the area between the Underground and the Surface. However, upon finding this Devil, Red notes that he doesn't look scary at all. In fact, when the Devil sees him, he waves, gives him a big smile and simply says, "Hi, bud. I'm Sans. Ya come up here to enjoy the view?"

Summary
Monsters get reborn after death. Reborn monsters don't remember their past memories. They either turn into a demon or an angel based on their psychological state. The more pure the monster, the more holy they are. Same thing for the other one. When they have more darkness and pain the monster has before death, they have more power as demons and their tails are longer. An angel and demon being together meant that the demon is tricking and manipulating the angel.
Papyrus became an angel after being sliced by the human, and Sans turned into a demon for his soul was full of anger, hate, vengeance, and regret.
Being reborn usually meant complete loss of memories. But Sans can remember everything. Clearly. He can remember his beloved brother, his "unique" spagetti, the horrible torture experiments by the doctor... EVERYTHING.
So what happens if Sans meets with his brother once again? Will he do his unspoken job? Or will he silently watch and protect his sweet little angel?
Try finding that out yourself.
