Frisk has a curse that makes a flower grow on them every time they die. In an UNDERGROUND full of ruthless monsters, it's hard to stay alive. They meet a friend who is their only source of protection, and they start to think, maybe they'll make it out of the underground after all. But will they? Frans. Based on a story with the semi-same name on tumblr. FRISK IS EIGHTEEN!

What would happen if the six human souls that were used to break the barrier ended up reviving themselves and returning to the surface with no memories of what transpired underground. They went on blissfully for many years... until the truth of what happened finally comes out. Now the humans whom were killed are looking for answers.

If she could go back in time she would grab that USB, jam it into her computer and download that stupid game. To hell with exams and getting into uni. This was a matter of life and death. From before the war to its aftermath and the game.

When Jamie moves to a new city near Mt. Ebbot to stay with his cousin/big sister, he never would have guessed he'd find some new friends and a new family. Done as a request for pokemonsora01. :)

getting stabbed to death and being reincarnated as a skeleton monster isn't the weirdest thing in my life but having multiple soulmates in Another Universe that's just too much and I have to deal with a creepy fan who believes that she is my soulmate and the others as well.

Daniel. That was his name, the one thing that he remembered from a past life, one before the Underground. He doesn't remember what his last name was- Hell, he doesn't remember his parent's faces- Yet, that doesn't matter anymore. Why, you ask? Because he's King, and he'll be damned if he allows this chance to slip from his grasp. [A story of a man of monsters. A story of change.]

A prophecy, whispered between darkness. A child, born of light and shadow. A promise, given only to men and beast. A war, breaking them apart. A perniciousness, resulting from the taint of an Angel. Scores of tragedy and pain. A story of many lines, many events. A cursed catalyst to unite them all. Frisk's rise to power fails.

In the dog days of summer, a happy event sparks a terrible realization in Toriel regarding her immortality and the future consequences it could entail. 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)

"Frisk...why did you come here? Everyone knows the legend, right...? Travelers who climb Mt. Ebott are said to disappear." We all know the Undertale, a story where one Determined human changed the lives of every monster in the Underground forever-for better or for worse. Why did Frisk climb that mountain?

Chara and Frisk’s journey through the Underground... With a bit bigger body parts than normal.

Frisk loved Papyrus's hands. Just a fluffy little introspective drabble set in the Papyrisk Chronicles universe, but it can very much be read alone.

Another DoubleKid. But what if his story, while not intertwining with The Hacker and The Anarchist, finally came to light on its own? The era of DoubleTale continues into one of the 21 original stories. Based off of DoubleTale: Rewritten by XWolf26

"Most likely you know the public's story: a tiny human child with an insane amount of DETERMINATION falls into the Underground sealed under Mt. Ebbot, befriends everyone, and then SAVEs the King and Queen's children whom they thought they'd lost a looong time ago. Nice story, right? Well, the REAL story is a lot more complicated, so buckle up. Things are about to get interesting."

Un travail en apparence facile qui pourrait bien être plus trompeur que prévu.

Almost a year ago, Chara's world was ripped apart. Now, with almost everyone she ever loved gone, the sharp pain has been replaced with an ever-present heartache. Nothing seems to matter anymore. What hope is left?

Mao becomes friends with a popular group of boys who she happens to have crushes on. There's drama of course- Angst, Lemons (mostly), fun, and y'know- fuckboys-
