    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

    Thrown into a world she only knows as a game, Ava Davis must choose her path in this magical underground wisely.

    Will she go the coward's way, abandoning all the monsters that reside there, or stay true to the morals that she holds so dear?

    These questions need to be answered soon, for time is running out for them all...

    ...and there's no more Mr. Nice Flower.

    Summary

    The Barrier was destroyed. That was the easy part. In this brave new world of humans and monsters, Frisk has accepted the responsibilities of Ambassador. The fate of an entire civilization is hanging in the balance, so for them not much has changed. For the people of Ebott's Wake, on the other hand, a lot of what they think they know about the world is going to fly out the window. Especially if they think they can safely underestimate or ignore this child that speaks for the monsters. That particular learning curve is going to be exceptionally sharp.

    Summary

    Undertale AU Garbage. LOVE, love, smut, angst, edginess, and self reflection. A story about teamwork and friendship, with lots of puns, ships, and feels. Full of head-canons what might deviate from the original story and/or AU ideas.

    Worlds collide when shortcuts resonate. Will they be able to find their way home?

    Summary

    Underswap's Gaster is not a Nice Monster. Not at all.

    Years of being alone have broken Blue, and only a fluke accident has him tumbling across the multiverse and landing smack dab in one of the ones you really don't want to be in if you're from a Tale 'Verse.

    Red knows the mask that Blue wears, so does Edge.

    Its the same mask they put on every day themselves.

    Summary

    If anyone wants to read the story on my tumblr, or see some SERVERTALE drawings and poems, you can find me here https://spectroamer.tumblr.com/
    Humans and monsters were living on the surface in peace. One day, they realized that the earth will be overpopulated soon and that they need to think of a new place to live. After a lot of research and co operation between the greatest human and monster scientists, the Computerworld was thought of. It would be a limitless world inside of a single advanced computer where everything would be a possibility. Both humans and monsters were working on the project, but, one day, monsters were accused of stealing the blueprints of the Computerworld and a war broke out. The monsters lost and were trapped in the unfinished, small world. They needed 7 souls to activate the portal that would lead back to the real world. Luckily, someone succeeded to bring 6 souls before they got trapped, and now they only need one more. Meanwhile, a war between the same people who killed many innocent monsters and only a few heroes is raging across the high tech Ebott city.

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    This is my first fanfiction on AO3, so constructive criticism is appreciated!

    Sporadic updates because life. ;u; I'm sorry. Longer chapters to make up for inactiveness: 5k words minimum.

    Summary

    These days the King is more interested in weird metaphysical biology than physics, which means that Dr. Gaster's project to build a decent generator is not only woefully underfunded, but he has to deal with cruddy technology short-circuiting and exploding constantly. He'll have to pick a team, and indicatively, one of the applicants only has one HP. And he blows up Gaster's office during their "interview."

    May or may not contain: tea-drinking, depression, cats, anxiety, swearing, annoying dogs, death and near-death, gravity related injuries, conflicted Asgore, a non-Gaster Royal Scientist, crumbs of Toaster, humans, platonic Sanster, honorary science daughter Alphys, PICK UP YOUR SOCK SANS, unfriendly eldritch critters that don't like the monsters living in their caves, snarky fire elementals, monster souls and their curious properties, odd skeleton behaviors, magic malfunctions, and spatio-temporal displacement.

    Gaster as a friendly derp boss monster physicist who for once isn't interested in breaking the Barrier.

    Sans as an angst-ridden smol fragile marshmallow with malfunctioning magic.

    Alphys as the voice of reason that Gaster does not internally have.

    THE GREAT PAPYRUS IS ALSO HERE!
