Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.

Summary
𝗦𝗲𝗾𝘂𝗲𝗹 𝘁𝗼 𝗣𝗲𝗿𝗶𝘀𝗵.
𝙐𝙣𝙙𝙚𝙧𝙛𝙚𝙡𝙡 𝘼𝙐---
In a world where everything seems to be slipping through his fingers, Sans knows that the only way to survive is to do whatever it takes. With the weight of her life in his hands, he faces a terrifying truth: some things are worth losing, but he’ll do anything to ensure she isn’t one of them. In the end, the question isn’t just how far he’ll go—it’s whether he can live with the cost.
---
He remembered the conversations and the words they’d already spoken a thousand times over, the responses they’d known before they’d even asked. He remembered the fights and the endless, grueling battles where he had lost, and then won, and then lost again. The victories became hollow, empty echoes, and in the end, even the victories felt like failures.“You ever wonder,” Flowey’s voice trailed off, dropping into a hushed murmur that seemed to blend with the sound of water lapping at the stone. “If maybe she was never supposed to come back?”
The question hung in the air, heavy and unresolved. Neither of them spoke after that. They just sat there in the swamp, a place that used to be full of life, now lost to time and decay for what seemed like ages.

Summary
'ALIENS ARE REAL IN ENGLAND', the headline rolling across the bottom edge of the television screen read. the news reporter babbled something unintelligible in their own excitement, before pausing to pivot and look at something off-screen. turning back with a wide grin to face the camera, they hurriedly urged the cameraman to swerve to focus on whatever it was that had caught their interest.
a spaceship, completely and utterly inhuman in design.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
or, in which you are an alien with an appearance strikingly similar to that of a skeleton monster. with a tongue that speaks only in an alien script, you are reluctantly relocated under heavy security to live with monsters that may be able to read your intent rather than the enigmatic language you keep throwing around orally.
━under the condition that they report anything and everything they manage to translate from you to the government.

Summary
Waking up buried in snow, alone, and with no memories but basic common sense?
Check.
Seeing numbers, words, and broken code floating around every object and surface?
Also check.
Looking like a walking system crash—with one eye red, the other computer-blue, and a body flickering like corrupted a light?
Triple check.He doesn’t know who he is.
He doesn’t know what happened.
And most importantly...
He doesn’t know why everything feels like he shouldn't be alive.Everywhere he looks, the world speaks in code—and he can read it like instinct. Names, stats, system files, broken timelines. And yet, the more he tries to remember, the more he feels like a mistake.
Note from the Me:
This is my take on Fatal Error—a much more none canon, wandering version of him. He’s not fully canon-compliant inn terms of power and has a different origin and personality. It’s a reimagining: glitchy, lonely, and filled with questions, bad puns, power and some more bad puns. -
An Unexpected understanding by Ari_Artzzz404

Summary
when the monsters finally were freed from the underground, the humans were outraged, though that was to be expected, humans tend to be afraid and disgusted by things the don't understand, and they didn't know the whole story, And the monsters were wary and cold towards humans due to this.
therefore, the tension between humans and monster remained at a constant high.
Y/N was a human who wanted to understand. At first they were wary of monsters, they didn't hate them, they knew that at a lot of the things humans say about them are probably wrong, but they never really knew or not, so they were overly anxious around them, especially with a SOUL defect already making them anxious. until an event with a monster makes it clear to them that human bias is true sin, and that it was time to be open their mind and change.

The multiverse reboots every once in a while, and error is the only one whose memories remain intact.
He was left behind, and thus the destroyer of the worlds could only cradle his rust-stained memories, watching as everything familiar faded. He observed the ebb and flow of the multiverse, while he himself gradually extinguished, as if the flame of anger in his heart had lost the fuel to keep it burning.

Summary
After almost eighty-nine genocidal routes and forty-six pacifist routes.
Frisk, wanting to mature a little and wanting to save the monsters after playing so much with the resets, decided to start a new pacifist route. At the beginning everything went as it should and there was nothing strange, but...
Why does Papyrus sometimes look at him with terror?! Why do they all have scars on their bodies?! Where are the human souls and where did they go?!
Frisk was very confused and didn't know what to do, he tried to do a reset, and in the new route... nothing changed and everyone still had scars.
