Summary
Papyrus didn't know why he decided to wander over to his Mettaton poster and rip it off his wall. He didn't know why there was a safe hidden in the wall. He didn't know why he knew the code.
And he certainly didn't know what the note along with the syringe filled with a red liquid meant.
All he knew was that he needed answers.
...
After an incident with DT, Papyrus remembers.
But it's all too much.
Now, as his sanity vanishes, he finds himself faced with an impossible task:
Defeat the human and end the Resets.Series

Summary
The Messiah is beaten!
Or rather, a piece of it has fallen...
Frisk, with Asgore's blessing, has set off from Voxis City to France to pursue the next sect of this vile cult. But her true goal remains hunting down and killing Demon. By her side is Trinity Obaseki, the reformed daughter of the German sect's leader, though his influence over current events remains far from over.
As the world expands and truths are revealed, Frisk is forced to confront the darkness within in a most visceral form.
Who controls the timeline? How deep is the Messiah rooted? Can Asgore rebuild Voxis and maintain his reputation? Will Greg fall to his fury and go down a path of villainy? And what about Terrence, what's he doing in China? Most importantly- what does Toby Fox think of all this? Nothing, probably.
Join us on this journey into the next step of Voxistale's journey!Series

Summary
You mum drags you to her boring science lab, forcing you to help her with her research, against your will and interest, until late at night. You're in a lab late at night, what could go wrong?
(Reader is 15 so NOT a romance between reader and the skelebois.)

Summary
Y/N is a normal, definitely not Mary Sue with Main Character Syndrome girl with ordinary life, which gets turned upside down by her younger sister Frisk and bunch of monsters (who definitely won't be their fanon counterparts with zero personality traits). But a CERTAIN skeleton does not like her at all (and won't start loving her for no reason at all after a few chapters just because she is the main character, trust me bro). Will she be able to win him over...and uncover a terrifying secret and save the day (like always)?!
Note:
This is a 'parody' inspired by my bad experience with2020 fanfictions, do not take any of this seriously, characters are supposed to behave like their 'fanon' versions as I remember them from the year of glory, 2017: more shallow than that tiny creek behind your house. Look at this as a source of entertainment of a bored person. Thanx :) -

Summary
well this is my first story, so it probably won't be that good, though I'll be happy with any support, readers, suggestions, or critique I do get!
Frisk and Chara venture through the underground, dealing with their pasts, futures, and complex feelings.
There will also be Charisk eventually. :3

Summary
Everyone knows the story of Undertale. But what if something changed? Just like the tale for-told, King Asgore, King of monsters, declared war on all of humanity after both his human child and biological son died to the hands of the humans who lived in the village on the surface. But tragedy struck, and Asgore died in the war he created for himself.
The King’s ex wife, Queen Toriel, now finds herself trapped within a dire situation he had left for her. She managed to bring the war to an end peacefully like she wanted, but at the cost of her fellow monster’s freedom. The humans created the barrier, and trapped all monsters underground. Queen Toriel, her heart now broken into pieces and now remolded into something darker, set a rule where all humans that fall into the underground won’t be killed, but will instead be made into slaves.
But what happens when it’s a child that falls into her newly established hell? Will her heart be opened up once more? And will a silly little skeleton help her find the most precious thing she lost? You’ll just have to read to find out.

Diving for Justice, Freedom and Managed Democracy by Dangeresque_On_Ice

Summary
The Monsters were dead.
They must have been, the Federation of Super Earth had said so; annihilated during the Great Galactic War along with all the other threats to Managed Democracy. So Clover was understandably confused when he set out to find the five missing Cadets only to discover a whole society of Monsters sealed underground.
What’s more, these Monsters were nothing like the tyrannical, Freedom-hating killers history had portrayed them as.
Things just weren't adding up. But why? It’s not like Super Earth would have lied, right?

Summary
Fazbear Entertainment had always been able to easily control Anthros in the past, taking great advantage of their lost memories for far too long. And now, after all this time, these memories have been brought back to light, restoring the missing parts of each effected Anthro.
Yet, while the Anthros may have regained their memories, with it comes a realization that some may need process their pasts at a slow pace. As it goes, the good memories aren't the only ones which have been restored. Not all is simple clarity as each Anthro recalls their individual pasts, and puzzling line of family generations.

Summary
The legend of the DELTA RUNE foretells a prophecy. It says that one day, the underground will go empty, when an angel who has seen the surface returns, and saves everyone. People in this world may become cynical, they might not be able to muster as much faith in it, they could have heard the prophecy so many times it's become meaningless. Those people, they form a sentiment in the prophecy. That it instead refers to an angel of death, and that the underground will go empty... because no one is left alive.
Now, you may have heard this story before. It's fairly widespread, and in that, allowing the angel to exist... it usually ends in a battle of ideals.
This, what I am offering you now, is a spin on that classic story. This story has always been about what you believe in. Examining what kind of emotions you cling to, the kind of emotion that may make you stake yourself on others, do things your heart isn't in. Exploring this sentiment is the purpose of this deviation, it is an experiment.
There are incredible bonds between people in this world. Sibling bonds, family ones, friends.
How much is worth clinging onto, and how much will clinging onto it hurt you? ...Well. You made your choice long ago.

Summary
The legends said you'd meet kind monsters.
They didn't say the flowers would be rotting.
They didn't say the Underground would be starving.
And they definitely didn't say what happens to a kid who falls in after the ending.Igor is quiet. Careful. Not the kind of kid who should be here.
But he fell anyway.
Now all he can do is survive—if the Underground lets him. -

Summary
After Basil’s death, Sunny runs towards his home in an attempt to end it all, but Aubrey follows him and she prevents him from dying. Sunny tells her the truth and now they have to face it together.
After moving, they find themselves camping until something happens and now the two will travel together in order to escape the Underground filled with creatures that were only believable to see in fantasy books.Notes:
the Undertale tags are there because I want to make an Omori x Undertale fanfic, but there won't be anything related to Undertale during the first two chapters except for some references to Mt. Ebott and its legend, but around Chapter 3 or 4 onward, the Journey through the underground will begin!
So stay PATIENT!Series

Summary
Considered one of the most important works of the 2Xth century, Memoirs of a Young Human describes one human's journey through one of the most mythical finds in all of history: The Dyrses Underground, in which an entire civilization laid underneath, unknown. Memoirs of a Young Human details much of the culture, people and history of the Underground and ultimately serves as a powerful message of how love can break all barriers, from language, to actions and to the endless violence that is war.

Summary
“Long ago, two races ruled the earth, humans and monsters. But there was a third race that was rarely known, they were known as aethers, a hybrid between the two, born when people from the two race fall in love. Decades before the monster/human war, there used to be millions of them, before the human prince ordered to have them slaughtered, leaving them a dying species. When the now king eventually waged war against the monsters, he used the rest of the living aethers to seal them underground, forcing them to give up their loved ones. Shortly after this, the aethers and the kings subjects mutinied against the evil king, putting an end to his reign, but not without great cost, as there was now only half a dozen aethers left, not enough to break the barrier. But they swore a vow, that someday, they’ll save their family and friends, along with all of monster kind. Many centuries later, on top of mount ebott, a mountain that says whoever ends up going there never returns. a young girl ends up climbing the mountain, in hopes of finding out what happened to the 7 missing children. But nothing could ever prepare her for the adventure ahead.”

Summary
A human child by the name of Frizk climbs the forbidden mountain, Mt. Ebott. Her goal? To go to a new world in order to live a new life. While she expects an isekai, she instead falls into the Underground where she meets a talking flower. This flower has the ability to seemingly alter time. To the human's surprise, the flower is helpful and friendly. Now in the Underground, Frizk wishes to live a life amongst monsters. To do so, she must keep her human identity a secret.
Unlike the Underground that you readers may know, this Underground is different. In it exists a young Boss Monster, the child of the King and Queen who are still together.
This young Boss Monster wished from her youth to make the Underground a better place. In order to accomplish this, she became the Royal Scientist and started to improve the lives of monsterkind. However, in doing so, she ended up often overworking herself. Monsterkind treated her as the pride, joy, and second hope after the long-distant passing of their first prince, Asriel. Due to her habits, this Royal Scientist Princess lives a solitary, lonely life.
Will the two be destined to meet? Or will they continue on with their predicament, their lives never crossing paths?

Summary
Alcohol.
How did it all start? Maybe it was those girls and their cruel remarks? Perhaps it was when your father left for some new family? Could it have been that goodbye text from the only person who truly knew you? Or maybe it was all of the above, mixed with how easy it was to throw back a swig and let it all go?
The bottle became a solution before you realized it was a problem.
One to calm the nerves.
Another to blur the memories.
A third to forget how ineffective the other two were.Relief. Hangover. Recover. Repeat.
Eventually, the relief stopped coming, no matter how many bottles laid empty, the pain seeped through the cracks in your defence - so you looked for a different escape.
"Legends say that those who climb the mountain never return."

Summary
With a world-shattering wave of Determination, Frisk disturbs the balance of the multiverse and transmigrates to a timeline where monsters were never sealed underground. Their sudden appearance in Twisted Wonderland awakens a long-forgotten magic, and Frisk and Chara navigate the consequences while searching for a way back to their universe. Figuring out the messy effects of SOUL magic in a world that existed normally without it isn't an easy path, nor is trying to teach them how to use their SOUL trait's abilities… but Frisk had no shortage of Determination. Fortunately for them, it seems that the most effective way to fight against the recurring Overblots around campus was with their friends' newly established SOULs.
