Summary
It’s been just a day since Asriel’s life turned right way up again. Monsters have returned to the Surface at long last, himself included. He’s got his best friends—new and old—by his side, and both his body and SOUL have been restored to him. There should be nothing left to worry about.
But new threats loom and old habits die hard. It’s been a very long time since Asriel’s been able to trust anyone else to deal with problems. Especially when there are so many secrets that nobody can be allowed to uncover… and one that Asriel can’t bring himself to face.

Summary
I'm just gonna explain a few things about this series.
This story will be a month or 2 after Frisk fell down.
Everyone is still underground. (For now hint hint)
My oc will be a little girl named Charlotte that was hiking with her mother but ended up getting lost and fell into the hole.
Charlotte has long brown hair, red eyes, a scar that goes across their left eye, 5 years old, extremely talented, loves singing and playing intrsuments, survivalist, doesn't show emotions very good, adult like attitude, Empatheitc, helps others when wants too, and only talks when she wants too.
Charlotte's parents aren't the best. (Literally)
Some things may be confusing in the story, but please roll with me! Thank you!
I think that's it for an explanation.
The story will start with Charlotte finding the hole and falling.

Summary
It has been five years since monsterkind left Mount Ebott with the help of Frisk. Now a teenager, that’s six months they had been living far from their people with Toriel, who got hired as the first teacher for humans and monsters. Frisk lives that forced exile badly, but summer vacations are close enough to go back to New New Home and see all those they left behind.
Soon enough, Frisk realizes something is wrong with Sans. Despite the forced smiles, the skeleton is suffering in silence. Worried, Frisk decides to investigate. Is he still mad for all these timelines they did something irredeemable, or is it something deeper?
One thing is for sure, those vacations won’t be like the others.

Summary
After being so rudely discarded, everyone’s favourite vessel finds themself in the world of Undertale, replacing Frisk’s role in the story. Surely plopping in a soulless human with no life experience won’t change any of the events of the tale we know and love, right?

Summary
Sans is the Bane Of Your Existence. Pranks and Puns haunt your days whenever he is near. Unfortunately, Papyrus is your best friend, and you'd do anything for him. Even if that means taking care of his brother after an experiment gone wrong turns him into a massive, and even lazier, house cat.

Summary
Certativus: [kɛr.taːˈtiː.weː] In order to stir up strife, combatively.
For years Mt. Ebott has swallowed the sorrow, the mourning, the grief that mankind has gushed. Legends pass through the air, for those that enter, whether that be glory or greed, none return. Children disappear in the depths of night. Forgotten.
They do not remember the trek into the forest, nor the fall that followed it. But, for a mountain supposed to be empty, they are never alone.

Summary
Your best friend of eight years, Brynlee Sloane, was a main character.
It was clear with the way she found herself in awkward and coincidental situations almost constantly. Love triangles, mean girl bullies, an aunt that she's lived with almost her whole life, parents' mysterious disappearances, etc. You'd been there to see it all. And, from all the movies you'd watched, you knew that you were ultimately the basic main character's best friend. You were constantly disregarded by whoever Brynlee attracted and you were always there to comfort her after a potential lover broke her heart. The constant shade you were unintentionally left in from your best-friend slowly wore on you over time. Though, one day could change a life drastically.
Or, in this case, one blue fish at an amusement park.

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
Frisk’s dad Sans and uncle Papyrus are royal guards. That’s pretty much all Frisk knows about their jobs. Frisk doesn’t know much about their past nor what they actually do for work. All they know, is that they have to wear their monster disguise every day or they’ll be caught. They know that humans who are caught in the underground die. But what happens when Frisk slips up and accidentally alerts the whole of the underground to their presence?
Sans is struggling hard trying to balance being a parent and his job. He wants to be around for Frisk, but he has to satiate Asgore lest he find out Sans’s secret.
Papyrus really wants what’s best for his family. He’s worried about Sans and how stressed out he’s been. Sometimes he worries that Frisk doesn’t have enough social interaction.
I’m so excited about this, I’ve been working on this project for 3 years at this point and I’m so so so happy I’m finally able to post it. It’s still a work in progress, but it’s going well so far! Constrictive criticism is appreciated, especially if you catch a spelling error of mine (just be nice about it please).

Summary
“so, you’re uh…” the blue skeleton in front of Sans had an odd pinched expression.
“an advanced AI” Sans clarified and his social program hissed at him to relax his posture “nothin’ more an’ nothin’ less”
Sans’ analytics quickly gathered the expression of each skeleton monster in the room to come to the conclusion that something was off. He carefully noted the odd atmosphere as the chime of a directive made itself known.
FIND A WAY HOME
Something in him settled and the red circlet at his temple evened out to a mild yellow.
“you sure about that pal?” the first skeleton’s red twin said as he picked his golden tooth after a pause.
“my social programming’s pretty complex, it can be hard to tell i‘m just a machine” Sans tried not to let incredulity sneak into his voice—of course he was sure.
“THAT CAN’T BE RIGHT” a lighter blue skeleton said rather intensely and Sans’ analytics scrambled to see where he went wrong “YOU HAVE A SOUL. RAZZ CHECKED YOU EARLIER”
Sans blinked at the accusation
Or
Sans is pretty convinced he’s a machine, everyone else is convinced he’s got issues.

Summary
ESP: Despertar en una jaula no estaba en tus planes.
Tampoco perder tus recuerdos... ni descubrir que ciertos nombres duelen cuando intentas recordarlos.En un lugar donde la luz del atardecer se filtra entre el polvo y los secretos, dos hermanos esqueleto te observan con más atención de la que deberían. Uno es ruidoso, orgulloso y demasiado protector. El otro sonríe como si nada fuera grave... incluso cuando lo es.
Y mientras tus recuerdos se desvanecen, una pregunta empieza a pesar más que todas las demás:
¿Qué parte de ti no quiere ser recordada?
------
ENG: Waking up in a cage wasn’t part of your plans.
Neither was losing your memories… nor discovering that certain names hurt when you try to remember them.In a place where the light of dusk filters through dust and secrets, two skeleton brothers watch you more closely than they should. One is loud, proud, and far too protective. The other smiles as if nothing is serious… even when it is.
And as your memories begin to fade, one question starts to weigh heavier than all the others:
What part of you doesn’t want to be remembered?
