Me and my brother are attempting to do a story together but we are to lazy to do allegences. Please do them for us and don't be upset if your character isn't used. I will use it on a different story. FINISHED

They made it out of the Underground, and of course something drags them back. Old ghosts will come back to haunt our friends from this underground in this tale. Don't forget to R&R!

Sans thought it was finally over, but it had really only just begun. Something dark lies; something he forgot, and it's only a matter of time before old memories, and old purposes, are revived. When a happy ending is all at once a nightmare, Frisk and her friends are faced with either saving a dear friend, or saving the world. And saving both might not be an option.

Echopaw and her sister, Frostpaw, have just began their apprenticeship. Every thing is going fine until strange scents start appearing around the territory, and cats start mysteriously dying... This is my first Warriors FanFic. I do not own Warriors, Erin Hunter does. This is Book 1 of the Growing Darkness series.

It's been almost three years since Frisk had come through the Underground and disappeared. Undyne has taken up the task of continuing what Asgore had started. Two siblings fall into the Underground, and must make their way through a now-militarized world.

A Mage of Void absconded from a Null session into a different one. He hides out in The Veil, using computers, books, and Skaian technology to learn all he can in the many years before entry. This is the journal he writes in to keep his mind intact, and to share all he's learned for whoever decides to read it. And soon he'll have to fill a role that he never knew even existed.[edit]

Took a whack at what life would be like for the Undertale characters once the story ends. Set in a more or less 'realistic' universe (as realistic as can be when it comes to talking skeletons and eating ramen in battle). Sans is constantly expecting and dreading resets, struggling with nihilism to make the best out of life. Intended for mature audiences, not to be taken seriously.

Underfell is a living hell for Sans. He's mistreated, unloved and unwanted. By a random act of fate, he is sucked into a portal at his darkest moment and spit out into the Underswap universe, where he meets his alternate counterparts. The long healing process must now begin and Sans and his Papyrus must both make choices that will change their relationships forever.

Papyrus remembers things. He remembers being king of a desolate and empty underground. He remembers a house on the surface with a bright blue door and a bright red car. He remembers the sharp sting of a knife slicing through his vertebrae. Papyrus remembers all these things. Sans doesn't know. No one knows. And he'll keep it that way.

Frisk suddenly left 4 years ago, with a single note left on the counter that read "Don't look for me. I'll be back." That's enough to make any concerned friend worry, but as the friends get closer to the heart of the problem, they realize there's a much darker side to the surface. (Post-Pacifist Run - Modern AU - Female Frisk)

Meet Yvonne: A bright young woman with pink hair, an affinity for writing, and no idea what she wants to do with her life. One night, however, she decides for the first time to take action with her life. This results in her making the decision to move to Beach City. There, she meets a young boy named Steven and his 'interesting' guardians. One of which she may have feelings for...

When Papyrus naively trusts a stranger, he finds himself trapped in a completely different world -the Netherworld. Strangely enough, they folks there seem to like puzzles just as much as the folks back in the Underground. Meanwhile, Sans, fearing the worst, sets off to find his kid brother and realizes that things aren't always as black and white as they seem.

A mysterious new girl falls into the Underground and her life is changed for life. This is a story about love in the face of darkness!

A one-shot about how Frisk says farewell, for good this time. Rated T for Death and some other stuff.

He never thought he'd end up here again, but here he was... Back where they had come from. No matter how much you hate them, you might just turn out to be just like the one who raised you... Takes place after the King Papyrus neutral ending.

(T for cliffhanger, death, murder, dieing, violence, and grief.) I am so not sorry. :) ((Chara/Frisk is female for simplicity))

But today, all the laboratory employees were buzzing in excitement, gathering around boss outside the cafeteria; he was carrying a new shipment of samples, but what warranted such an enthusiastic reaction by all the employees? You walked closer, when he opened the box a soft blue glow emitted from inside.

During the fight with omega flowey, what happens when the souls don't come? What happens when Frisk gives up, and flowey absorbs the last human soul needed to shatter the barrier? NOW ONLY A SHORT ONESHOT. WILL MOST LIKELY NOT CONTINUE.

(Songfic oneshot) (TRIGGER WARNING) Life is so repetitive. Like a vicious cycle, over and over and over. Frisk, in high school, soon realizes this. Her realization came right after having a run in with a pack of not-so-kind kids at her school. Sick of this endless mayhem, she attempts to end it horribly. It's a good thing she has friends there to save her from this awful fate...

What would happen if the barrier was never broken, and Frisk lived in the Underground from ages 10-18? What if Chara found a way to manifest in the real world without Frisk as a vessel? What if Sans fused powers with Frisk? Find out!

Inspired by the popular web game "No One Has To Die." A leak of deadly TAINTED DETERMINATION happens in Gaster's lab. Alphys, scientist-in-training, arrives to move in. Security doors slam shut, alarms ring, and one thing is certain: someone is going to die.

Frisk's whole adventure was nothing but a hallucination as their brain tried to cope with the pain...at least, that's what their human captors keep saying.
