Summary
Following the War of Humans and Monsters, both belligerents agreed that a second war would be too devastating, instead opting to coexist peacefully.
Centuries later, tensions run high, and the two kingdoms are on the brink of war once more. The unlikely duo of Frisk and Chara, heirs to the throne of the Human and Monster Kingdoms respectively, must learn to set aside their differences and cooperate to prevent another calamitous war (amidst backstabbing, dubious ruses, and similar malefaction), lest they face total annihilation.
And try not to kill each other, of course. Though, that's sort of one-sided.

Summary
Two souls in the Underground, intertwined by fate and by a prophecy that keeps them apart.
Heads up before you read:
In this fic, Chara is alive and far from a good person. They’re not a mindless killer, but a narcissistic kid. This is not a fluffy Charisk story. Chara and Frisk’s relationship is deeply toxic.Please look at the tags before you continue.
I've been experimenting with third person for a while now, and I've grown to like it a lot more than first person. For those who came from my other fic, which I promised a sequel for, I’ll try my best, but I’m not sure how that will go now that I’ve fallen in love with third person and started a new long fic. Please don’t be angry I will try to finish my other fic as well.

Summary
“I CAN’T OPEN THIS BLASTED BOX!! IS THIS SOME KIND OF JAPE?! WHY WOULD HUMANS SELL SOMETHING LIKE THIS?!”
The sound of a trombone plays.
“SANS!! WHAT DID I TELL YOU ABOUT PLAGUING MY LIFE WITH INCIDENTAL MUSIC?!”
“that you love it and want me to do it more?”
“SANS, I WILL DUST YOU.”
“pretty sure that’s workplace harassment.”
“IT IS NOT!”
“is too.”
Envy closes her eyes and tunes them out again as their argument devolves into yelling. She just has to get through today, tomorrow, and the rest of her life. That’s not so bad.(AKA, a less-than-pleasant dojo owner who has too many problems of her own to deal with forgets to take down a "help wanted" sign.)
Please read the before-story author's note of the first chapter!

Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

Summary
The story of the human and monster war, now days just another bedtime story, but that is for the humans. Monsters live trapped underground, they have gone through famines, epidemics, lost of hopes and dreams, and all because the humans were scared of them. Hope came back when finally, a "human" fell down. But it just brought more misfortune.

Summary
What if the war never happened the way they said? Peace was restored (somehow), and now the world is mostly fine—if you ignore the politics, ancient grudges, and the occasional existential crisis. Frisk and Asriel didn’t ask for power, but power showed up anyway. Now they’ve got to juggle diplomacy, family drama, magical weirdness, and each other…

Summary
It’s done, after all these years, monster kind can finally be free of their prison in the underground. But not all is well. A specter from the past haunts Frisk, and only by learning to move on from the past that never was can they both find peace. Meanwhile, another specter haunts the world. A war is brewing once again between the ways of old, and the way of the future. Dreams of world revolution and a classless society reignite, and soon the world will be divided between those who wish for a brighter future, and those who cling desperately to their own past that never was. Soon, the recently emerged monsters will need to choose what role they will play in this conflict, and what their place will be in the world.

Summary
“did he….did he ever do something else than a tantrum? Did he ever…cross the line with you?” Frisk says, fearful of Sans’s reaction and answer. “your personality…isn’t just a facade to hide anything in your home, is it?”
…
saying that those questions caught Sans off guard was an understatement.
his eye sockets were widenly open and his White dot pupils were tiny.
shocked.
“…”
“what.” He says, not believing what he just Heard.the heck is this kid accusing my bro of?
…
alright, this does it, this kid is hiding something and i uh…have to know what it is , because this isn’t right. Sans thought.OR.
Sans date scene, but secrets are revealed and Sans isn't happy in the end.
basically, a remade version of a post i did on undertale's reddit with the same name as this one-shot.
based off an au where Frisk is a depressed teenager, made by Seb_sketches on twitter. -

Summary
Lost in their misery, they don’t notice the figure who’s climbed through their trapdoor until he’s cleared his throat. They immediately shoot up in bed, trembling fingers digging into their knees as they look for the source of the noise. They can only gape as their blurry gaze rests on a short skeleton, whose face is twisted with abject, blatant concern.
“you’re here?” Sans asks, though he doesn’t sound all that surprised.
“You were watching the vacuum cleaner commercials?” Frisk hiccups their reply, reaching up with a clenched fist to wipe away another offending tear.

Summary
Hush now, little one. I have a story to tell. A story about humans and monsters.
Frisk Estrella lived on the surface, and was just one face in the crowd of thousands within the large city. Buckling under the pressure on his home life and internal forces preying at his mind, the last think Frisk wanted was to end up being on the run from the cops. Unfortunately, some don't get a happy life.
After a confrontation leads the boy wanted for murder, Frisk ends up in the bottom of Mount Ebott, where he discovers a civilization of mongers just below his feet. To anyone, they would be horrified, and would try and venture through to leave.Frisk however, finds himself growing familiar with this place of monsters, and soon enough, thinks about staying. But as he makes friends and allies, hundreds of years of history begin to rear their heads as Frisk must confront enemies that could threaten not just the Underground, or humanity, but the very nature of existence as well.
In order to save his friends, and himself, Frisk must have DETERMINATION to survive.

Summary
'She was always the adventurous kind, right? Her just going missing for two days is fine, Right?!'
Y/N had always been... aware. Whether it be a small, useless detail about the world around them. To the entire personality of the person in front of them. They always seemed to know everything they needed to.
Yet when their sister went missing, when days started repeating over, and *over* again. The top of Mount Ebott, the place no one returns from, sounds less like a threat from a lost time, and more like a release
---------------------------------------------------------
'the kid's still going? huh... i doubt that'll last much longer.'Sans had seen everything. He'd been through *everything*. Genocides, pacificism, death, and resurrection. A never-ending loop he could only sit and watch, never being able to break from the cycle he was forced into by the morbid curiosity of a child who could barely comprehend the power they wield. Yet, the timeline had never lasted this long

Summary
Frisk has always been good at dodging and always been able to take a hit, but what if there were a different reason for that? What would happen if Frisk had to adapt to an abusive life when they couldn't feel pain?
Frisk dodges like it's second nature, avoiding most attacks easily. As for the attacks they can't dodge, well how much of a threat can they pose if none of them are fatal? Frisk just needs to make sure to care for them afterwards...

Summary
"El odio es un sentimiento... interesante. Puede hacer que te cuelgues de el, cegarte por la dulce tentación de vacilar y envolverte en el, de dejarlo meterse profundamente en su cabeza, convencerte de hacer cosas horribles, de convertirte en una criatura horrible. Pero... el odio tambien puede impulsarte, ayudarte a encuentrar los modos y establecer los lineamientos para cumplir lo que te propones, incluso de cara a un panorama complicado o de pocas oportunidades. Es una emoción divertida, ¿No crees?"
Solo una interpretación diferente de como podría haber sido si Sans hubiera obtenido determinación a través de su odio por el nuevo dueño de la línea de tiempo, Frisk.

Summary
Undyne was a runaway foster kid. Gaster was a genius. Asriel and Chara were royals. Frisk was an orphan. Sans and Papyrus's childhoods were...messed up, to say the least.
The childhoods of Undertale Characters aren't really expanded on in the game or AUs. So, let's explore their childhoods in my AU. =)
Edit: I changed a few things.

Summary
Life wasn’t difficult for you. It wasn’t necessarily easy either. But what you did know was that you got a brand new job at Ebbott library, in a small community that was settled on the edge of a National Park.
It was beautiful and quiet, until the barrier broke and introduced you to a rather charming skeleton that wore fuzzy pink slippers just about anywhere. Now you have to figure out how you’re going to bring him home to your parents.

Summary
If there is one thing Frisk was proud of, it was their poker face.
It didn’t matter the situation, whether they were playing in the pretty autumn leaves in their back yard or getting chased at by bigoted fish monsters. Their face would remain blank.
