    Summary

    It was just a subject a creation made by Gaster an on going experiment to create the perfect killing machine a monster with the determination of a human cable of ribbing anyone apart. But Gaster made a lethal mistake how would Gaster contain a such creature with an intelligence that matches his own and magic to rival even the strongest of boss monsters, the king. The answer? This horrible creature escapes into monster society injuring multiple monsters that came across its path. There seems to be no end to the violence and the terrible creation in question, calls itself Sans.

    It is a lot better than it sounds I just suck at summaries XD

    Summary

    Far away and long ago, two races ruled over Earth, Humans, and Monsters. However, why is it that when all was at peace the races began to stir conflict out of nowhere?

    (F/n) has always been bad luck and to be frank, was never more than a pawn into someone else's game. When you think you've finally bested your inner demons they conquer your mind once more, caging you to the decision to either fight against your own race or fight against the family that never stopped believing in you.

    Summary

    This is an au inspired by the Temmietale AU where everyone is Temmie. ParasiTEM takes place in a version of undertale in which temmies are bloodthirsty flesh eating parasites that turn others into temmies when they are fed upon and killed by said temmies.
    Somewhat like zombies except in this AU temmies are intelligent and very hard to outwit.

    Frisk the main character was turned partially a temmie themselves and must fed on flesh in order to prevent themselves from feeding upon Sans and Papyrus who are two young skeletons who are being protected by Frisk and their friend Flowey so they can get them to safety.

    Summary

    A human falls from Mount Ebott and no one cares or will miss him.

    Reason? One thing leads to another and they weren't human, well, at least not totally...

    They were half monster.

    Summary

    (Y/N) (L/N) was once an icon; an absolute icon to the masses. But destroyed out of jealousy, she is given a new chance with a brand new power and is thrown right smack dab in the pre-main plot of Undertale, where everything hasn't gone to shit yet from Frisk's meddling.

    And she'll be damned to let these poor souls rot beneath ground, not when she has the power to stop it.

    And dammit all, she WILL persevere and achieve her goal!

    ...

    Now if only she wasn't so damn attached to Flowey.

    Summary

    Life used to be simple. Days used to slide through one another with little difference. Then the monsters were freed. Chaos ensued for a seemingly endless stream of time before the world calmed again. Peace between the species was just starting to be explored when the Outbreak occurred.
    More or less a series of short one shots vaguely held together by plot.

    Summary

    Papyrus wasn’t expecting to find another creature when he went wandering in the forest of Snowdin. He ALSO never expected to meet a human! As the Great Papyrus, he couldn’t just leave them to fend for themselves! Though...humans weren’t exactly...COMMON...in the underground..

    (A kinda AU where I try to imagine if Papyrus met a human WAY before the royal guard, before Frisk, before everything, when he is still an adorable baby bones! This is my first story ever, so I’m sorry if it’s ala suck.)

    Summary

    "They know," he wheezed, unusually quiet. "Sans, they know, you said they wouldn't-"

    "No," Sans' cold blue eyes stared him down, "I said they wouldn't know what WE did. I never reset, Paps, that was on you."

    Summary

    A skateboarding stunt goes wrong and Chara is taken to Dr. Gaster's office to get her broken ankle set. She's afraid of doctors, but a small punny skeleton who barged in on her appointment to bring his father his lunch might be just the distraction she needs to help her get over her fear.

    This is the story on how Sans and Chara became friends in the As Sweet As Chocolate Nice Cream series.

    Set in a universe where Asriel stopped Chara from going through with the buttercup plan. This is a sequel to A Twist in Fate: Saving Chara, but can be read alone.

    Summary

    Sans has always been running. Whether it's from bullies or from himself, it didn't matter to him. Now he's made a choice, a choice that would change his life forever.

    Sometimes you need to know when to give up, in order to see where you're going next.

    Summary

    Gaster notices things, but doesn't want to admit that something is wrong. Sans has been going through a lazy streak, nothing more- right? Though perhaps behavioral issues aren't the only thing wrong with his oldest child.
    ---
    An AU in which Gaster doesn't fall into the core, and is Dadster to our favorite skelebros. Sans has nightmares of alternate timelines/universes- and is spiraling out of control.

    Sometimes, repetition causes conflict.

    Sometimes, chaos brings balance.
