    Summary

    A week passes after the SOUL of PERSEVERANCE tears through the Underground, yet New Home remains empty. Alphys, alone, awaits rescue in her childhood home. She survives off what she has, but the time comes where water no longer drips out of the facet, and her fridge is licked clean. If she wants any shot at getting out of this disaster alive, she'll have to face her worse fear: the Unknown.

    Summary

    Horrortale Sans is stuck in an Underground where the only source of magic is dust.
    His senses have since learned to embrace dust--he always: smells it, tastes it, feels it, and above all, sees it.
    A new dust pile cropping up is the most excitement Sans gets ever since things went bad.

    Empress Undyne died long ago, having been eaten alive by her ravenous subjects. No ruler had dared claim the throne since, for they too would be eaten.

    Sans's magic now runs red with Determination and it's the only thing keeping him together. Constantly bombarded with painful memories of the past, Sans does his best to reinvent himself.

    - Horrortale AU eventually crosses over into the Undertale AU.

    Summary

    The spectrum of creation is vast, holding countless timelines and universes. If each of those has their own set of monsters, they must have their own Firebrand, too.
    !READ AT LEAST SOME OF A DEMON'S TALE FIRST!
    Unless I say otherwise, I own none of the alternate universes explored.
    Updated: Alphys and Undyne wake up from being knocked out, and see just what awaits them.

    Summary

    1 year after the events of Undertale, triggering the 'King Mettaton - Neutral Ending', another human falls into the depths of the Underground after a climbing incident. Sin, short for Singani, journeying through the transformed land - meeting Monsters that would later become her friends - becomes raveled in an adventure that promotes her as Mettaton's 'Rival to Fame'. The goal is to sway the love of the monsters to the rebellion's side and get Metton to listen to reason since becoming dictator.

    Such things don't come easy, however, when you're wanted by the Robotic King and your only haven is the rebellion of monsters that have remained hidden from Mettaton. Don't worry, though...

    Death is the last thing Mettaton has in mind for you.

    Summary

    That is where this story finally comes in, she was just a little girl when she saw her first monster. A sharply outfitted man made of a brilliant purple fire which lit the room; he wore a fur white collar attached to his charcoal colored coat and high dollar shades outlined in silver that was just about the only feature on his face. The jagged grin that was made up of white flame could make any human tremble in fear. Most children cowered at the sight of any monster, but her eyes were lost in amazement to the fire elemental. That would not be the last monster she got to see while standing at her father's side. Her father, he was the head Mage of their family, a ruthless and ambitious man that knew how to use both his magic and his money. Both of these allowed them to fend well in New New Home alongside monsters. He was clever, even though it took a toll on his sanity. This lifestyle still came with many dangers as they were still greatly outnumbered on a daily basis, even within their own circle.

    Summary

    Trapped beneath the mount Ebott, you have to endure a life without Papyrus, Toriel and Asgore who have been killed by Flowey.

    The majority of the monsters blame you for what had happened, but at least you still had Sans to protect and take care of you. Only thing was that Sans had become possessive of you after his brother's death and was ready to do anything to keep you by his side, even if meant taking your soul.

    Summary

    This takes place in a post Underfell King Papyrus ending.

    Struck by under population, King Papyrus makes it law that all monsters, that were left alive by the murderous little human, had to procreate. This leaves Sans and the king in a tight spot, there are no female skeletons and both skeletons are sure they are the last of their kind. Fell!Sans proposes something, with the help of the first Royal Scientists machine to travel other universes, he will find mates for breeding purposes.

    Tale!Sans is having his first sub heat as a female, this happens when there is only males and the strongest one undergoes a gender swap. He knows this means that Papyrus would have to be his mate, that won´t do, they are brothers for the Angel´s sake! So he does what he does best, HE RUNS.

    Summary

    Sans is getting fed up with the Resets. They're just the same Genocide over and over. So with Alphys' help he creates a solution, albeit a very painful one.

    Due to that , Frisk with Chara and a whole hell of a lot of LOVE tagging along make it to the surface without Erasing everything. When all havoc is created on The Surface a 10 year old child seeks shelter in The Underground.

    There they find a small handful of monster's who'd survived the human's killing spree.

    Will they prove to everyone that not all humans are horrible and return hope to everyone in the process?

     

    And what if they can free them all? Then what?

    Are they the true angel?

    Summary

    It's the King Mettaton ending. I think we all know what that means. So how does it get so bad?
    Pieces based after the ending. Should be mostly chronological, but don't hold me to it.

    I wrote this in December and still can't think of a name so I'm posting it anyways.

    Summary

    Frisk is never, ever going to go back. The demon wants them to, but they won't. It's always the same now. Even if they miss the flowers and the friends and the sunlight. Even if they desperately want to escape the black void of neutral ground....

    Summary

    Hello Dearie,
    If you’ve found this note, you’ve probably found my friend with it. He’s been hurt a lot, and he isn’t getting better here. If you can’t help him, or if this isn’t your handwriting, please pass him on to the nearest Muffet. She’ll know what to do. Thank you so much, dearie, and I hope your life will go better than mine.
    Cordially,
    Muffet
    P.S. His name is Sans, and his favorite food is ketchup.
