    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

    The experiment was simple in principle, and even if it hadn't worked as planned, it would have been a step in the right direction. But something went wrong; time and space turned inside out and upside down, and the best hope for monsters to escape the Underground went up in flames with half of the C.O.R.E. Facility. Years later, after the Barrier was finally shattered, that unplanned experiment bears unexpected fruit. And Royal Scientist Wing Ding Aster has a lot of catching up to do.

    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!

    Summary

    A freak RESET in a No Mercy Run that went a little differently than Sans remembered that caused him to regress in age to a baby bones. Papyrus is left with few options; try to hide his literal baby brother from everyone and attempt to keep him alive without telling anyone, consult Undyne and Alphys, ask the insane Queen, hidden away in the Ruins for aid, or ask the one monster he knew had a daughter who liked his brother -- he didn't want to think about what kind of relationship was there -- for help. What else can he do but try and build a strategy from each option? Hopefully with Undyne and Alphys he can figure out how to turn his brother back to an adult, and Grillby can help him figure out how to keep Sans alive. Papyrus tries to ignore the golden flower he knows is following him and tries to find answers for his questions. Can he raise his brother if Alphys can't figure out what's wrong and how to fix it? Can he keep him safe in a world that's KILL or BE KILLED when a baby needs love and attention to grow? Can he trust himself? Can he trust Grillby? And why can't he ignore the feeling deep in his Soul that nothing is truly the same?

    Summary

    Doing that October thing where you address kinks or things in October! I thought it would be a great way to show off some of my ideas, get the gears moving for another story. Instead of doing it daily though, I’ll combine kinks and themes together weekly in a chapter. See what we come up with.

    It's October! The best month ever in Ginger's opinion! So while at a bonfire party Ginger and her friend Jasmine decide to full fill a dare to take a picture in front of an abandoned sanitarium only to find one of the lights still on. Jasmine goes in and doesn't return, so it's up to Ginger to find her. What Ginger finds instead is that she should have stayed home as a monster who was once lost to space and time is reborn.

    Summary

    Dr. Wingdin Gaster has kept his experiment, 6 (Sans), hidden from the outside world. An unexpected visit from the king forces his secret into the open. Not knowing anything other than the lab for the entirety of his existence, 6 must reconcile the world he's known with the world he's been hidden from. This is a story about good intentions, bad mistakes, and the fine line between being a monster and being human.

    Warning: Because this fic seeks to tie up some loose ends of the UT backstory, spoilers abound. Don't read if you haven't finished playing the game through to your heart's content.

    Summary

    Undertale is a popular video game, but it knows when it's being played. Five of its characters can remember the way the world used to be, even after the game itself resets, but until now they have been unable to affect the outcome for the better. As such, this game has never once gotten its happy ending and, as such, is adapting. Two wrongs make only a greater wrong, after all.

    This is Genocide Route Number Ninety, and five alone will have to change the course of the game, before the game changes them.

    Summary

    "The darkness, however, Wingdings, is not home to you, but it is also something that merely exists, just as well as light. Don't venture too far, and don't let it make you forget about the outside world." Being a skeleton of science, Dr. Gaster is used to deductive reasoning. When the tight rope between humans and monsters begins to snap, he finds that the answers aren't so easy.

    Summary

    G's life was pretty good. Asgore had managed to take control of a nice section of the city, and he had appointed G to be one of the lead agents and officers of their Mafia.
    Not to mention the occasional disruption here and there. They were always fun.
    But then, Asgore hired a few new recruits, one of which was a human girl. Never had a human joined before. Asgore was known for being ruthless and dangerous and definitely not a fan of humans.
    And wouldn't you know it, he had appointed G to be her instructor and trainer.
    Perfect.
    Just perfect.
    Now G had to deal with the reckless, stubborn, and sassy girl that he now had to try and train and the upcoming war between Mafias.
    But that's just the beginning...

    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!

    Summary

    */still flailing and muttering indecipherable nonsense/
    *Also I added a thing here already but it hates letting me make changes to this stuff for some reason?
    *Thank you all so much!! All of you! There's so many! Hahaaaa this is fine x}
    *Really though, I never expected this to pick up so many readers, and so many of you have expressed your reactions and concerns and I just, I love that you guys love it ^-^
    *And I made a quick thing to celebrate 200 kudos!

     

    *Updates Saturdays~
     

    *Here's part of what Dovequeen gave that started this:
    "The AU would mainly be focused on the skeletons being little kids, them adjusting to life in the castle, Toriel trying not to get attached (for fear of forgetting/replacing Asriel and Chara or losing the two skelebros like she did with them) and Asgore trying to fill the void his kids left with the skelebros and forget his grief by 'raising his new kids'."
