Sans can't wait to start his first day of kindergarden! But he has one big issue, and Gaster isn't sure starting school is a very good idea...

Frisk woke up in their bed. Their old bed. Had their whole adventure been a dream? Perhaps. But does that really mean that none of it was real? The monsters they met along the way certainly don't seem to think so. (Original post-pacifist AU. Rated T to be on the safe side.)

Set after a true pacifist run, this story shows some of Frisk's everyday experiences with her cool and…flamboyant friends. Mostly based in funny and cute situations on the surface, but with an upcoming plot concerning the resets, a punny skeleton and a little human with a stripped sweater. (Fem Frisk)*(T Just in case)

This is an AU in which Frisk is tiny compared to all the monsters, only a few inches tall. Because of the size difference between Frisk and the Monsters, several things in the game happen a bit differently. Or maybe not at all. I'll be using one-shots to show those differences. G/t, macro micro.

The first time Frisk enters the underground, they finally feel like they have a family under Sans and Papyrus's care. They discover, however, that there is more mystery, pain, and love behind all three of them and the Underground itself. (SANSXHAPPINESS) (Agender Frisk)

Everyone has something 'wrong' with them. Something to make them hate themselves. In this series of oneshots, Sans helps you realize that the things you hate so much, aren't so bad after all. He helps you learn to love yourself. Some subjects include self-harm, bullying, bulimia, anorexia, abuse in many forms, self hate and more.

(oneshot turned into story) Frisk comes home from school one day with a black eye. She won't tell anyone what happen either. Sans gets suspicious and follows her to school, not liking what he sees when he does. (Previously called Bullies are going to have a bad time...)

Papyrus was and is a lively skeleton, and moving to the surface didn't change that one bit. How does a cool dude like him deal with things like interdimensional threats, complex emotions, and a lack of spaghetti? By being the Great Papyrus, of course. Set after the True Pacifist ending, Frisk a little girl. ON HIATUS

{WARNING: This fic is INCREDIBLY old, has godawful typos and isn't finished, nor may it ever be completed.} A year passed since Frisk freed the monsters from the underground. They now live with Toriel, and every day is a new adventure as they do their best to help their new friends adapt to living on the surface.

The year is 2030. The monsters are now aboveground, freed by the then nine year old, now 11 year old Frisk. Papyrus is taking regular cooking lessons, Toriel's a teacher. And Sans? He's happy, finally. The nightmares have stopped, and he has an amazing wife and is an awesome dunkle to Frisk. But one day, he goes to tuck in said child, and finds a nasty surprise... SPOILER WARNING

(AU) The war has passed. W.D. Gaster and his son Papyrus remain as the only living skeleton monsters in the Underground. As time passes, Gaster notices that Papyrus is becoming lonely and saddened. He then becomes driven to complete his greatest science experiment yet - giving Papyrus a brother to call his own. But is it easier said than done? Please read and review!

This is why Frisk and Flowey should never mess with Sans' stuff…

All monsters can fuse when they are close enough, due their magic core. Except for one particular skeleton. Frisk tries to help their friend out with his predicament. After all, humans can't fuse... Right? (Rated T because Sans has a dirty mouth when he so chooses)

Relatively short, happy chapters about life on the surface where Frisk, Toriel, Sans and Papyrus live together. Some hurt/comfort but nothing depressing, mainly happy monster family fluff. Romance is not the main focus, but there is Alphyne, eventual Soriel and Papyton bias. Alphys, Undyne, Asgore, Mettaton, Monster Kid, Asriel and Gaster (and more) also show up.

After an accident, Frisk loses their ability to move their legs. What will happen to them? (cover image not mine!)

Everyone has just a little something that they would like comforted about... Contains NO NSFW, however another story on my profile will be dedicated purely to Undertale smut (not yet published). Please, no flames for anything! You can request a pairing, be it platonic or romantic, as long as it's from Undertale! There is some swearing.

Humans are made up of a body and a soul. Without its partner, the remaining part has difficulty functioning; when a soul is stolen, the body has no determination left. But what happens when it's offered, and some determination gets left behind? Well, it can't replicate a human soul. But maybe it's enough for the soul of a monster.

Frisk and Chara fell together... as twins. Both are polar opposites, and both affect the timelines in ways that no one in the Underground ever though possible... (first fanfiction, and I suck at summaries... rated T because I'm paranoid - FemFrisk and FemChara)

A post-pacifist story of life on the surface. Due to the difficulty of starting a new life, most of the main characters are living together. There is some occasional language, and things may turn darker in later chapters. Also, Frisk is female in this. Deal with it. Cover art is by Jendra, who drew this fabulous picture for me. Thanks Jendra!

Frisk was living on the surface with their new family. Everything was perfect except, the dreams that seem to belong to someone else. Something is left undone. The past is pulling them back. The world is reset, everything is undone. Somehow, they have to break the cycle and save everyone, and themselves. (pacifist run spoilers)

These are some ideas I have that could make some pretty decent comics, but I can't draw a bit, so I decided to write them in fan fiction form (NOTE: If you want to illustrate my comic ideas or post them on the Internet, I won't mind, as long as you credit me) Rated T for some language and safety :3

When there isn't enough Determination left in Frisk's soul Chara comes along and takes that chance to persuade Frisk to join her. What Chara wants is another genocide run but this time on the surface and why not get a bonus adding in humanity into the game too. Frisk doesn't remember who Chara was and in Chara's eyes this is the perfect time to achieve that goal. (Genocide Route)

Everyone is moved onto the surface now and trying to live normal lives. Sans has been acting mysterious and seems more tired than usual. Frisk thinks they've been more curious then they mean to be. As time flies by frisk learns more about their friends and learns not everyone respects the "ambassador for monsters". Soriel shipped. (Might be continued one day.)

11/11/2016 UP TO CHAPTER 5 HAS BEEN FIXED. Soon, this story will be ready to be continued. (LIKE EVERYTHING UNDERTALE RELATED, IT CONTAINS SPOILERS) A re-telling of Undertale, but from a... shorter... perspective. Like the source material, small changes make monumental differences. Does NOT contain Angst. Leans toward a more adorable side of the game.

Frisk has been stuck in nothingness for four years. When she finds a way out, she is bombarded with new questions everyday. How will she find out away to get away from the void forever? And who will be there to cheer her up? (SansXFrisk) Other minor pairings. Please tell me your thoughts. Horrible summary.. First story *Minor swearing..*

Chara is the unfortunate heir to a troublesome kingdom and runs away into the world of banished monsters to avoid their fate.

Gaster has been ripped from the void after Alphys tries to bring him back, but he ended up in the overworld. He was confused and alone in this strange human world, until he meets an abused, agender teenager named Frisk. Together, they might be able to put an end to both of their problems and perhaps, even find a friend in each other. Cover image drawn by LuminousMoonRay!

Light returned to his black eye sockets and Sans stared at the ceiling of his old room. Blue tears were slowly forming in the corner of his eye-sockets. His memories were intact not a piece missing and he knew why. This would be true fully their very last run and he had to make it count. He would keep that damned Flower away from his Frisk even if it was Asriel to some point...

{A pointless fic for a pointless AU.} Imagine a world where the eighth fallen human dies after falling down the chasm on Mt. Ebott. Now, imagine if dead humans have an incredibly small chance of coming back as a monster, and the eighth human does just that.

Something is wrong with Frisk. Every night and day she is plagued with dreams of killing her family, one by one. Now telling the difference between reality and nightmares has become much harder, and is threatening to tear her and her family apart.

When the True Pacifist ending doesn't end well, Frisk's friends are given the choice of risking their lives to save them, or simply taking their happy ending and walking away. And in the end, thanks to ASRIEL, Frisk learns that they're never alone. Mostly a combat story with some feels. Pretty long, getting longer. Will be done 'fore long. AU 004.

Surface life proves to be about as great as it can be, but for two brothers, something threatens to pull everything apart. Sans isn't happy, and won't let anybody in, leaving Papyrus to feel slightly less great than usual. Why? Wasn't this their "happy ending?" Smells like something is wrong.

Frisk falls down into the Ruins, but when they try to speak to Flowey, he doesn't understand them. Now he's on a journey through the Underground with this kid, and sometimes they get this weird gleam in their eyes and it looks like they're talking to themself. He doesn't have time for this when there's a couple of human souls that need to be stolen.

When Frisk chooses to go back to their human family, Sans still feels like he needs to be watching out for them. But if Frisk's got their own big brother to take care of them, what exactly is it Sans is trying to protect them from?

Long ago, two races ruled over Earth: HUMANS and MONSTERS. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell. Unfortunately, over time the monsters grew hateful, and swore vengeance upon all humans. The result? UNDERFELL. [Cross-Posted on AO3]

Frisk doesn't know the surface world, they've seen it but they were far too young to remember anything before they fell into the mountain and were adopted by the kindly Toriel. The Ruins are their home and they have no real desire to leave the underground as a result but what they do desire is to explore it and hopefully make a few more friends along the way. (AU)

How kid Sans got his 1HP. Gaster is Dadster. A murderous human attacks Sans. Dadster will not let this injustice go unpunished... Gaster also conducts experiments on a certain fish girl. Bye Gaster! Brotherly bonding. (There's so much stuff...)

Frisk wakes up on the cold floor of the Ruins with no idea of where he was or how he ended up there. Luckily a white-furred monster child finds and rescues him. But little does he know that he wasn't meant to be here and that the child he stole this timeline from watches on, silently plotting his revenge. AU in which Frisk takes Chara place (much to the latter's displeasure).

To Jessica her sister Frisk was the worst. Always getting praise, now more than ever because she 'freed' the monsters. Well, no more. Jessica was tired of her sister and the monsters, so, she planned to do what she believed to be the perfect crime.

Growing up, Frisk was forced to be perfect. If they made any mistakes, they were hit and yelled at. Now they live with Toriel and the others. When Frisk discovers their new powers, they are able to bring Chara back. What happens when Chara finds that Frisk is being bullied? Follow Frisk and the others into their day to day lives, dealing with their pasts and futures. Abuse mentions

Around 4 years ago Sans the skeleton vanished from Snowdin Town without a trace and no one could find him or where he went. But when Papyrus, Alphys, and Undyne find out where he was... They weren't expecting to see a little human girl with him, calling him 'Daddy! How in the heck did that happen! Read and find out! Fem Frisk! I OWN NOTHING! PLEASE REVIEW!

Post true pacifist ending (SO SPOILER ALERT). There are still some unanswered questions after the monsters are freed. How do humans interact with them? Why does sans have a lab? Who is W.D. Gaster? And why did Frisk go to the underground in the first place? The story continues where the games leaves off, watch all the characters you love adapt to their new lifestyle.

After several Resets, Chara and Frisk have managed to co-exist peacefully within the same body and bring the Monsters to the surface. However, all is not well as their tampering with space and time has drawn the attention of a being with incredible power...

For Frisk, life at Lady Irwin's was harsh, lonely, and worst of all, mundane. Until they one day find themselves atop Mt. Ebott.. *Undertale as told by Frisk' point of view,as always Frisk goes by they/them pronouns and their race/characteristics/etc is up to the reader!*

Just a bunch of stupid moments with Daddy Sans, Uncle Pappy, and Frisk Pure Fluff!

Have any burning questions? Ask away!

For the week of #cheeruptheskeleton, a weeks worth of little one shots in which Sans is finally truly and legitimately happy. One shots, because I can't draw well. They've made it to the surface, and everyone is finally happy, including a certain skeleton who finally comes to understand what real happiness is for the first time in years.

This story won't be continued. Sorry about that.

Frisk is trapped in the space between save files while Chara rampages through the Underground. All hope seems lost until Sans finds a way inside.

Sans encounters a very sleepless Frisk, and they try to think of a way to close the barrier without giving up Frisk. Pacifist AU!

A series of drabbles featuring the various characters of Undertale after their ascent to the over world once the barrier was broken.

One of Undertale Alternate Universes. An abused child fall down to the underground and must stop the evil king and queen, Asgore and Toriel, from hunting her down to death before it was too late. WARNING: Have spoilers on characters AND some topics about abuse and suicide. Sorry, but this is outdated. Rewriting the story right now.

Reborn as a monster, Frisk has a lot to deal with: meeting their friends again, learning to control the magic they've been remade out of, and, until they manage all of that, living in the same space as Sans and Papyrus. It's strange and scary, but they're safe, and that's all they've ever wanted. (WILL NOT BE UPDATED HERE; BEING REWRITTEN.)

After an unfortunate accident involving Undyne and Papyrus and cooking Alphys' place is now trashed and uninhabitable. While it's being repaired Alphys' stays at Undyne's and the lucky(?) Mettaton bunks in with the skeleton brothers. (After the true pacifist Route on the surface). Please R&R if you like :3

When frisk has serious insecurities reguarding themselves that cause them to have a full blown panic attack, sans is shocked to say the least. But when he wakes up a few hours before the time it should be, he knows he's going to have to kill frisk. TW: self harm, suicide, panic attacks.

It's been at least two months since everyone was released from the underground. Getting settled, having fun, random winking, stuttering, yawning, NYEH HEH HEH'ing, etc. and bad puns is all this story is about.

Everyone knows Papyrus is a kind person; he always has been, even as a child. However, he wasn't quite as strong and well-trained back then. Not a good combo when you get lost in the Snowdin Woods with all sorts of monsters-most not nearly as merciful as him. [a sort of backstory fic-papyrus is a young kid, sans is a teen] [cover art by bedsafely]

Takes place after the Pacifist Run. When Sans and Papyrus get into a bit of sibling rivalry, Frisk tries to see if they can help them forgive each other.

*Pacifist ending* One year has past since the barrier has been broken and all monsters left to the surface to live a better life. However even life on the surface isn't all that easy. Especially for somebody with friends and family full of monsters.

Frisk and the gang have escaped the nightmarish hell of the loops. Sans doesn't trust Frisk at all though, and keeps a close watch on them. A seemly meaningless incident has a huge effect on Frisk however, and starts a chain of events that Sans' could've easily avoided had he simply thrown a snowball with his hands instead. Intrigued? You better be. T for safety. Spoilers of course

Frisk decides to invite Napstablook over for a sleepover! Napstablook may still seem a bit timid and unsure of the idea, but the inhabitants are sure to give him a warm, friendly welcome! ...Most of them, anyway.

After being captured for the third time by Papyrus, Frisk starts to feel something. The various notes that were left for them made them realize how much they missed home. (Cover art by /sansy)

Frisk is an abused human child who runs to Mt. Ebott looking for an excuse to put them out of their misery, but instead finds a wonderful family. Rated T for some eventual adult themes, self harm, and suicide. Mostly frisk x sans.

Before the events of Undertale, W. D. Gaster and his two sons, Sans and Papyrus, live out their lives in the lab at Hotland. With their father consumed in his work, Sans has to juggle his responsibilities as his father's son and lab partner, as well as his responsibilities to his neglected little brother, all the while discovering the secret behind his father's true research.
