In a mafia run by monsters on the surface run by Don Asgore, Ms. Toriel, Mettaton, and Dr. Gaster, bodyguard Sans finds himself hiding a 6 year old child named Frisk from practically everyone, with this skeleton maybe changing for the better. This tale is told from the views of Sans in lowercase, Frisk in italics, and Flowey in normal text. Sorry I couldn't tag UnderFell Enjoy!

What if Chara and Asriel had lived? Their plan still failed, but they lived? Let's see what happens when the other humans fall down...

Sans tries to save his brother, over and over and over again. It never quite takes.

Frisk has RESET 365 times now. Every time since they finished the pacifist Route, all it's been is nonstop genocide. On the 365th RESET, Sans is determined to stop them.

This is a greenlight for a book I was inspired to write after a very... specific set of events. This will be an Undertale fanfiction, so I guarantee that tears will be shed while writing this particular story.

[Error x Ink] Ink has just moved into his very first apartment of his own in the big city! Perfect for a budding artist, his apartment is located in a somewhat rundown building, filled with interesting characters. One of them is his neighbor, who he hears making death threats to someone one night. Will Ink be able to stop him from becoming a murderer?

A Sans x Human!OC lemon for all the naughty boys and girls. ;}

When you start a new game in Undertale it's always the same thing, a protagonist looking extremely bored. A bed of buttercups that somehow let you survive and an entrance to the ruins. Now mabye you've seen Undertale animations where Chara is a ghost that only Frisk can see. What would happen if you swapped those around? What would happen if Chara landed on those buttercups?

A series of chapters detailing the characters' highschool adventures - through text messages - starting with their first day of school and the arrival of a new student. Humor, friendship, romance and shenanigans will occur! You've been warned. Future/potential pairings will be all the canon ones plus Charisk, and story is rated T for mild swearing and suggestive content.

Underatle AU's. Con toda honestidad, Ink nunca había sentido mucha preocupación o interés en los fantasmas… así que cuando uno se interesó en él, toda su vida se puso de cabeza, y no estaba solo en eso. ¿Quién podría haber pensado que un espíritu lograra lo que nadie más había podido lograr con Ink?

Peace is always a struggle to find. Rebellions, corrupt monarchs, flowers and gods. All of these are things on their path to peace. Asriel, Chara, the fallen humans and monsters strive to be freed. But Flowey, Frisk and Asgore will prevent their path from being reached. Will monsters ever be freed and find peace on the surface? First they have to deal with Genocide and war.

The barrier is finally open. Frisk and the monsters have no time to celebrate. Thrown amidst a world of distrustful humans and even more vengeful monsters, Frisk needs to find where her loyalties can truly lie. However, her worst enemy may be herself, and every rose has its thorns. (Sequel story to Howlingtale, an Undertale AU story. Warning for maturity. Rating may be changed.)

Another human falls into the underground. She befriends Underfell Sans and together they work to save the monsters from their underground prison before she gets completely covered in the lilies that are draining her energy and life. The human girl is about 18 or 19. Sans is maybe 5 or 6 years older. Sans POV. (Basically Flowerfell with a twist and then a happy ending)

A day at the park turned into an interesting encounter with 2 skeletons and an annoying dog. Thought this would be a normal day drawing in the park. Who knew I'd meet some handsome skelies...wait, I mean interesting, not handsome...maybe a little handsome...what am I saying?

Frisk's story after the underground! Frisk is a girl in this story as well as being shipped with Asriel! They live with Toriel and are in 7th grade.

It was a nice enough party, Alphys guessed. Three years on the surface was nothing to sneeze at, even if she's seen it all before. Being one of only two monsters to remember the resets did tend to make everything a bit duller like that. Wait, when did she set this alarm? Oh..OH! Time to resume a conversation with a certain someone...

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.)

With Monsters free of the underground, setting up businesses, and schools, navigating politics, rights being established, history rewritten, world views shattered, was it unsurprising then that it wasn't until after that anyone noticed anything off? "Join not the fay in revel, mind/Nor whirl around the elven track/for when in leaving ye shall find/Time dances not so merry back"

BARISTA!PAPYRUS, MALE/CHILD!FRISK, FLOWERPOT!FLOWEY, and the others join up in this oneshot that follows Papyrus' new job as a coffee shop barista. Papyrus' friends come to visit him at work and he finds that though they cause lots of mayhem, they make the day go by faster while providing him with fun and laughter.

A roleplay of escalating ticklish shenanigans, mainly featuring the skeleton brothers. New chapters will be uploaded every Wednesday and Saturday. (WARNING: Will contain NSFW bits, but each chapter will have a warning for anything unsuitable for young readers.)

Blueberry has a hard life.

With the monsters now free from the binds of the Underground, negotiations for the humans seem to be going well, until old secrets are uncovered. Will Asgore be able to deal with the growing mistrust between the humans and monsters? Or will he find himself being thrown into yet another war?

Has anybody ever wondered what happened before Frisk? This is the story of Undertale, starting all the way back to when Chara first fell into the underground, and continues from there. This is the full story. (Pairings and character lists change as the story continues)

TogetgwrTale is a undertale au about the 7 souls falling down and trying to survive in the underground together! Each having their own reasons and goals and making some new friends along the way! I threw in some mystery in there so Enjoy!

Sans is invited for a cup of tea with Asgore, who was feeling lonely at the time. As Sans is there, Asgore starts to feel strange, as if he needed some sort of affection, which Sans did not sign up for.
