    Summary

    Sans is conflicted by night terrors and vague memories from previous timelines gone wrong. They are starting to become more vivid and soon he starts to notice deviations from what he's grown accustomed to, and Papyrus does something unusual that changes everything.

    With the River Person out of commission, Sans accompanies Grillby on a replenishment run through to New Home, all while wrestling with a feeling he just can't break about his long-time friend. Hardship, embarrassment and mystery abound.

    (This fic is Pre-Pacifist/pre-canon with some embellishment, Rated T for Chapters 1-18, M for 19-43 for references to bad trauma and Sansby exploration. Final rating is Explicit - such content will have warnings at the beginning of any chapters and a brief summary in the end notes. Explicit scenes may be referenced by characters in the future so "E" rating it is.)

    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

    Honey finds his edgy counterpart all alone and roughed up in an alleyway during one of his late-night strolls that he insists on taking, and he realizes there is more to this skeleton than what meets the eye.

    Summary

    Many years ago, Monster kind was sealed underground.
    But then Frisk came along and saved them.
    However, after finding out about the few Monsters who weren't trapped under Mt. Ebbot, Frisk is determined to help them out of their prison, no matter what is takes. But of course, nothing is ever simple, is it?

     

    The nightmares you've been having recently are all just a mess. Darkness, and a single warped voice calling out to you. Whatever the person is saying escapes your memories, though, and all you can remember is two hands shooting out of the never-ending darkness to try and grab you. It soon becomes more apparent that these nightmares hold a deeper meaning, however, when a child comes to the mansion, bringing a few monsters along with them.

    Why do the human child, and the two skeleton monsters, seem so familiar?
    And why is your magic slowly turning into a shade of purple?

     

    Sorry for the crappy summary thing.

    Summary

    One human, a tiny little thing. Weak. Insignificant. A soul as red as blood. Stolen by by the Man who Speaks in Hands.

    Two monsters, young and fragile. Damaged. Defective. Souls as white as snow.

    He held them, he hurt them.

    They fled.

    And then his plans came crashing down.

    Secrets have come out, and there is nowhere to hide.

    But perhaps... He doesn't need to.

    A single human soul is much stronger than all of the monsters in the Underground combined.

    Summary

    "Sans, are you okay?"

    Silence.

    "..I'm guessing you're, uh, not really okay."

    No one said the road to recovery was an easy one.

    Summary

    Sans thought it was finally over, but it had really only just begun. Something dark lies in wait, something he forgot, and it's only a matter of time before old memories, and old purposes, are revived. When a happy ending is all at once a nightmare, Frisk and her friends are faced with either saving someone they love, or saving their future. And saving both might not be an option.

    Summary

    A story of two brothers, from youth through adulthood. Sans was so glad that he had heard that he had a brother, flinching as he fed magic directly into the tiny, barely glowing orange soul. The baby skeleton was staring up at his young face, emitting distressed whimpers at the pained expression that he couldn't help. Sans had almost been too late, ignoring his health gauge; which was dropping from 20 very quickly. Finally, when his vision was beginning to blur out, Papyrus let out a muffled wail into his shoulder as his soul stabilized.

    "don't worry, papyrus. big brother has you." Sans whispered, his maximum health settling at one forever for his reckless move, "you won't be alone anymore, i will take care of you."

    Summary

    This is a fanfiction based off of Zarlas' Handplates AU. If you haven't seen their work go check them out! http://zarla.deviantart.com/
    In this you follow the young human, Lillith Overwood, after she falls down into the Underground. Just after she thinks she's found a new home in the Ruins, she wakes up to find herself in a dimly lit lab behind magic blue bars. And when she looks around she's horrified to find two skeletal children watching her behind their own set of bars.
    { And oh hey I recently got a tumblr account! Just search up Cupcakezys! I keep forgetting to say in each chapter update so I figured I'd just put it here. If you have any questions about anything let me know there. Or if you just want to have a chat about Undertale/any Undertale AU I would love that too! (◠‿◠✿) }

    Summary

    Enosiophobia, a fear of committing an unpardonable sin.

    That fear is reality for Sans. There is no other choice though. If he wants the people he cares about to be happy, they must find a way out of the Underground and they are running out of time. When a new human Falls, he finds himself wondering what sin he will not commit to free the Monsters of the Underground. Would he completely destroy another living being just to escape from this place? Would he forgive himself if it came to that?

    Frisk/Sans. Alt. Universe.
    Not going to be a happy, fluffy story. You were warned.

    Summary

    The Underground isn't the nicest place. Make one wrong move, say one wrong word, and you're dead. Needless to say things aren't easy for Sans and Papyrus, escaped experiments of one W.D. Gaster, on the run from the scientist and the rest of the royal guard.
