(Undertale | Sans/Original Female Character) As it turned out, nothing was smooth sailing after they all went above ground. Problems were coming to them left and right - fear, politics, power, discrimination, and so on. They were met with opposition - too many to count - and with every step forward, they had to take five steps back, which wasn't ideal. It was why, exactly fifty resets later - with each loop spanning longer and longer - Frisk and Sans decided that a do-over was in order. Not just to the point when they were released. No. But all the way back Underground. Back to when Frisk first came upon the Ruins. Back to the beginning. They didn't want to, but they were left with no choice. There really was no possible way out. So they went all the way back to the only place humans couldn't reach them to reconvene and plan their way out. It should be easy. Despite having left the cycle for decades (centuries? dunno, they didn't really keep track), they'd gone through the motion so much that everything should be like clockwork - predictable and monotonous. Yet, something unexpected happened. There's another human in the Underground. One they hadn't expected to see so soon.

Corporal Adrian Shephard, a US Marine Corps soldier assigned to the HECU division, was sent off to Black Mesa for 'cleanup duty'. Despite the hell he went through, the marine somehow manages to escape the dangerous, alien-ridden facility against all odds and, after being 'detained' by the ever elusive G-Man, is then assigned a new mission many years later... to the UNDERGROUND! Accompanied by Chara Dreemurr, the first fallen human turned apparition, the two journey through the unprecedentedly large Underground for one, very specific goal... but what exactly was it? And is that all there is to it? In... time, all will be revealed.

The Underground isn't silent anymore. Frisk has a voice, monsters have feelings, and the consequences of every choice echo farther than anyone imagined. Pacifist. Neutral. Genocide. All routes converge in a story where every action leaves a mark. Dive into a manga-style retelling of Undertale like you've never read before. Undertale™ and all original characters created by Toby Fox. This is a non-commercial fan adaptation. The cover credits go to @_oyo.art (Instagram)

After escaping the Underground and getting clipped by a truck, an amnesiac Sans ends up in the home of a vet, a doctor, and their daughter. He's certainly nothing they've ever seen before, but they can't just let him suffer either, so he becomes the unlikely son. So when Frisk falls into the Underground, Sans must return home to the place he was born and raised. Can he and Frisk free monsterkind from the mountain, or will they make a home Underground with the family Sans lost long ago?

Seven children fall into the Underground........... Each carries a different Soul............... Each carries a different truth................ They do not speak............. They do not know each other......... But the Underground notices them....... As monsters watch from the shadows and fate begins to bend, the meaning of Determination is challenged........... Because this time.......... It isn't just one human who fell........

Book one! 2nd book is Blood And Bones. This is a Sans x reader! Monsters have finally reached the surface. Sadly, it took the sacrifice of their loving friend, Frisk. She died age 10 breaking the barrier. Now (y.n) arrives, and begins to fill a hole in monsters hearts. She is able to help them heal the bonds between humans and monsters....... At least in this timeline. Warning: -------- If you are sensitive to blood, gore, same sex relationships, or suicidal thoughts/suicide then tred carefully. *the cover art is not mine, and neither is the art inside this book, unless a note says otherwise* *This book is a genre winner of The Red Crystal Awards!* If you are viewing this content on a platform besides Wattpad, you are likely at risk to a Malware attack.

It's been 5 years since monsters emerged from Mt. Ebott. They integrated into society rather quickly, but they still have people who disagree against the Governments decision to give them rights. Personally, you think monsters have better morals and attitudes than humans do. And who new that all you had to do to gain new friends was to get stabbed in the leg? When your insane brother escapes prison unexpectedly, you never have been happier to have friends who care about you. However, one monsters smile keeps you filled with hope and determination along with something you denied yourself of years ago...

How many times have you seen this world, how many resets does it take for you to give up hope? Does anything even matter after all this, does trying do anything? Will the struggle help at all, can I even believe in anyone anymore? The only thing keeping me going now is my resentment.

What if there was an anomaly in the Underground? No, not Frisk. Not Chara either. Someone else entirely. How could a few measly children stand to this supposedly immortal foe and save the Underground from destruction? Is it even possible to do so? Only one way to tell... ~o0o~ Disclaimers before you start! •There is NO fanon ships. That means no Soriel, Papyton, etc. The only ships are Torgore (in the past) and Alphyne. •This is NOT an x reader. I dislike those types of stories. The reader will have no part in this, and they will not be shipped with anyone. •This exists outside of canon to an extreme. For example, Frisk is the second human and not the eighth. •There will be OCs, but only for a few humans and they still technically exist in normal Undertale. •There is a sequel. I'm planning on rewriting it after this one, as it is much more random and definitely needs it. Clanky, plot holes/retconning, etc. It's more of an OC thing, to explore them and their issues, than an Undertale thing, but it has its similarities. •There will be some explicitives. It won't be unnecessary or excessive, only when it fits the situation and character. I will not be using any slurs, as that's just plain disrespectful, even if some of them apply to me. Credits: Undertale, obviously, created by Toby Fox and Temmie Chang. "The Time Before" by ANinnyMouse42 is the backstory for Sans in this AU with some adjustments (mainly since that was very close to my original idea before I read it and I don't want people to think I copied their masterpiece or smth, if you haven't read it please do so, it's really good). Some things will be in reference to the other books in the trilogy or "From War to Science" by Emotistic-optimistic. If you haven't, read that too. It's really good (along with its sequel). The cover was made by me! Have a good day! (Also, the title is a placeholder, if anyone has any ideas that make more sense, please let me know.)

Hi there! Feel free to ask anything you'd like! I, The Great Papyrus, will try my very hardest to answer every question I receive! Or... At least attempt to... Ask Away!!

After monsters were driven to the underground for many years, a human, Frisk, comes along and changes everything. She must learn how to survive the monsters there and must choose to kill or show mercy... [This is mainly a retelling of Undertale in third person Pov, mostly following Frisk. The plan is for about 3 'seasons' at the least for the story Im going to eventually tell.]

Frisk Traicionado version StoryShift. Recordad que los personajes no son mios sin nada mas...QUE ESPERAS LEE!!

The Pacifist Route is complete. The monsters are free. Frisk should be at peace. And yet... their soul trembles with something missing. Someone. Chara. The one who watched, who guided, who lingered through every path. An old, impossible bond begins to pull them back-somewhere between memory and reality. Frisk returns to where it all began. In the silence of the Underground, something awaits. But not all presences return without consequence. (Note: Frisk and Chara will be non-binary. But to make reading as smooth and uncluttered as possible, Frisk will be gendered as They/Them, and Chara as He/Him.)

(There may be some Undertale or other AU shippings in this story so let me know or comment what ship you wish to be included, thx! There might also be some sensitive things mentioned through the story so as a small warning, if you are weak with it, I will gladly have this sign, 🔴, as to warn of something is gonna come up, thank you and please enjoy ^^) Papyrus has always been a happy, innocent soul in the undergrounds. For his entire life, Papyrus was the positive, determined monster to keep up his guard and heal anyone with a broken heart. He lived as a little smart kid that was always wanting to dive deeper into both the knowledge of the Undergrounds and even secretly, the surface world in which he has been fascinated to study from his home in Snowdin. As he grew, so did his bravery and responsible nature to protect those he cared for. Even for strangers of the entire Underground. His older brother, Sans, and Papyrus's friend group couldn't ever be happier to have him the way he is: innocent, happy, persevered, pure, brave, and most of all....determined to become part of the Royal Guard. But after meeting up with a question and a ghost of negative pride, accidentally hearing the truth from who should've seen more in him, nightmares of the death of his brother, mentally losing the only support he's ever had, Papyrus felt an emotion that he should've never had, an emotion nobody should ever feel...... .......................................heartbreak.....................................

Crossposted from Archive Of Our Own Monsters have long forgotten the Judge through the passage of time. Reduced to myth and legend. What will happen when a certain skeleton is realized to be the Judge long forgotten. How will he deal with the certain societal pressures that have now been imposed on him? Will he ever be able to live up to the feats of his predecessors? What happens when time anomalies and timelines get into the picture? Will he break or will he persevere? Did fate perhaps make a mistake when choosing this skeleton? Only time will tell.
