Long ago the humans went mad. Monsters built massive walls around their cities and huddled for protection, living out their entire lives within these fortifications. One day Chara appears, very much like a human but in many ways not, and insists they are a "person".

Since she was Five years old, Ten year old Frances "Frisk" suffered from frequent Epileptic seizures after being diagnosed with Epilepsy. One day, whilst out with her parents, a seizure causes Frisk to fall into a hole in Mt Ebbott, leaving her trapped in the world of monsters. Now Frisk has to survive this new world whilst having to deal with a medical condition at the same time

"So, you really want to hear my side of things?" the young goat boy asked. "Well, I... I guess. But it's a long story, okay?" A poetic retelling of the greatest tragedy and the greatest redemption the Underground had ever experienced.

According to Legend, Monster souls are Made out of Love and Magic. Human Souls are far more Determined, therefore they do not require these things. This is the Story of a Monster who Fell Underground and Learns what it means to be Human.

Two years after monsters were freed and reached the surface, Lucius finds himself a strange power. The ability to turn back time using his determination. But a power this great takes a heavy hit on one's mental state and Lucius wasn't the first person to hold that power but the third. Its only a matter of time before those that came before realise what's happening. Weekly updates.

This is a collection of stories and one-shots that would make too much work to make separate books for. There will be multiple ships and AUs in this so if you don't like the ship and/or AU then don't read or skip to the chapter you want to. Reviews are appreciated so I know how you all are enjoying or if there's something that needs to be fixed.

Undertale, one of the coolest games around. Simple story, excellent characters, and endless fanfiction potential. But what if it wasn't just a game? What if it could be free of its true and final enemy? The Player.

"El jugador" ha muerto... Y ahora todos quieren JUGAR. En la peligrosa Ebott City, radica una constante inconformidad por habitar monstruos y humanos en un mismo lugar., desatándose conflictos delictivos que atentan con la vida de los habitantes.

Sans, overcome with depression and yearning for the past after the past few horrible years, is determined to do better for his brother's sake. To accomplish this goal, he decides to pay a visit to the grave of his deceased childhood friend Chara.

Chara found themselves being bored. Maybe this new human that can see and hear them can relieve them of their boredom. The only issue is that the new human is a baby. Can Chara help the baby survive the Underground? How many years will the baby lose to the ability known as Reset? Why am I asking so many questions?

After an abandoned genocide route and an abnormally placed TRUE RESET button, I have now respawned on the field of buttercups with no way to do another genocide route. No weapons, and the other characters that can remember timelines know nothing of it. Can I redeem myself in the underground? Let's find out. Sans X OC Rated T for that. PS: I suck at summaries.

When monsters first come to the surface, panic ensues and the monsters and Frisk flee. Can a family who's been trying to get Frisk back help? SansxOC. :)

Art trade with Taleea on Deviantart. The thoughts running through both Gaster's and Gen's heads as they were looking to escape the Void. Takes place during "Mendertale" comic done by Taleea. :)

Not once did I expect to die one Saturday morning after saving a poor woman, but that's exactly what happened. Next thing I know I'm in a hospital bed with a crying kid who's supposed to be my sibling? And-wait a minute! Did you just say their name was Frisk? Old Author: " Amber Mint " Rayne Talks

This is my first fan. So, this might be bad

How this started? I wasn't sure. Whose fault it was? I didn't care. All I knew was that I wanted it to end. (Frisk…or Chara…or…someone… kills. And they reset, many, many times, until something new happens. And they are free.) ((I do not own Undertale.))

December 25, 2015 Mysterious black briars destroyed the whole of Ebott. Every inhabitant was lost except for a pair of brothers. Not long after, a tragedy claimed the younger one. Since then, the sole survivor did everything he could to prevent the calamity from spreading further.

A Christmas Party to remember. Mixed messages, mentions of mistletoe, and general shenanigans? What more could you ask for?

A love letter. A letter of devotion, of love. A letter that comes from the soul. A special letter. But perhaps some things are more broken then they seem. And maybe something else has to give the push Sans needs to send it.

She knows there is only one way for her to age again, to avoid such a fate. But things are no longer as simple as they were over a century ago. (Soriel, Sequel to All These Broken Pieces)

What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. All he has to do is break through one wall... (A rewrite of DT.)
