    Summary

    You've worked with difficult people before, but...these skeletons were on a whole other level. If Undyne had warned you just how crazy they were, you probably wouldn't have agreed to help the queen in the first place.

    But due to unfortunate circumstances, Mt. Ebott was the safest place for you to be. And in order to stay, you had to join the Royal Guard.

    Now, with threats of war breaking out, you find yourself torn on whether or not you should help this mixed bag of good and evil monsters.

    But one thing was for sure...you'd sooner die than give up your newfound refuge. You were ready to fight and protect your home.

    And these skeletons didn't seem to understand that you were serious.

     

    An Undertale Reverse Harem Story.

    Summary

    Papyrus is sick of Sans treating him like a child, and (Y/n) is tired of being who everyone expects her to be. When these two find each other they both immediately hit it off, but will Sans or her family try to interfere in their good times? Probably good thing the Great Papyrus is good at sneaking out and (Y/n) is bold enough to be herself! This story is completely self-indulgent and purely smut based plot (its barely there), but if you wanna come along on the journey of Papyrus getting to say fuck and be an adult strap on in friend.

    Summary

    I meant to die.

    I'm trying to gain my bearings and earn my place in this new world. At first I thought it was just so I would never have to go home, but maybe it's also so I can stay with the bizarre, slovenly mage I have come to care for.

    I've heard of soulmates... Could this be it?

    (Nah basically I have been obsessed with Undertale for far too long and I have far too many head canons, and I need to put them down. Switch the monsters for mages since I don't want to have to deal with ecto-peens, but basically this will be a drawn out romance between Sans and Y/N. I'm serious, they won't meet until a few chapters in and they won't be touching pinkies till we are at least in the double digits of chapters. I have elaborated on the basic world building Toby created and also build on his characters, so there's different sets of rules they play by, and the plot is pretty different from the game. Idk man I'm bad at selling my shit lol. Kinda rough subject matter, read the trigger warnings ok?)

    Summary

    A jar of dust is all Papyrus has left of his beloved older brother. His world has turned upside down; the only thing that matters to him anymore is making it up to Sans for being an awful younger brother before he can finally join his dust-jar. However, a famous robot comes back from his national tour and is the only one that doesn't treat Papyrus like a ticking time bomb. Can Mettaton convince Papyrus that life is worth living again? (overall tw: death, grief, mourning, depression, sxicidal thoughts) (this story is heavily inspired by the "dustjar" au by @zarla on deviantart, please check out their content!!!)

    Summary

    Set after the events of MyTale. The multiverse holds limitless possibilities, and multiple chances to do things over. Maybe struggling to do things right will build the path toward redemption? Or at least give some closure to a guilty and troubled mind.
    Multiple fourth-wall breaks. Self-insert as Frisk. Some suggestive stuff here and there, but no romance that's out of canon. Can be read as a stand-alone if you don't mind spoilers.

    Summary

    After Frisk leaves the Underground taking all the human souls and killing Asgore, the underground becomes mostly a wasteland. Monsters dusting due to the core failing. Having to attach prosthetics to avoid magic leaking from their lost limbs. Sans and the other boss monsters begin to slowly lose hope, and their minds.

    After 5 human souls are collected, a set of frail twins fall from a height that should have killed them. They meet a creature who wants to help them reach the surface, only the children are better off down below then above. Or are they? Join Tet and Ares as they go through the underground encountering monster only told in myths. But who are the real monsters? Who knows, maybe these monsters were just the family the twins needed all along…

    Sorry, hi I’m new to this. Please be nice in the comments:) Criticism is fine. I’d love feedback from you all. I’ll upload a better summary once I get into the swing of things. This is my own original au in the works known as Machine-tale.

    Summary

    Evalynn never gets what she wants, her parents weren't bad parents, they just weren't around for reasons Evalynn cant understand. She never got a partner, she was way too anxious to even try to flirt with anyone. And not only that, she ALWAYS finds herself in trouble.

    ————————————————————————————————————————————————

    Papyrus constantly got what he wanted. Sure, he didn't have parents, but most of the people he knew didn't, hell, in this shithole parents don't care about their children anyway. He always got any girl he wanted, he had girls kneeling at his doorstep just to have one night with him. And not only that, the barrier broke on his birthday!! He couldn't ask for more!! He ALWAYS got everything. Until the moment he walked out of the underground. There were three other versions of his underground standing there at the same time. Yeah....birthday ruined.

    Summary

    Alphys was sure that this time —please, just this once— everything was going to be all right. The machine she took so long to create would give positive results, help in that conflict, and things would change for the better. And she got all the expected results... or almost.

    Or where a machine malfunctions and the Underfell characters see themselves in human flesh. And they will apparently watch themselves.
