    Summary

    Your inability to die has led to a millenia-long life of nihilism and guilt. You do your best to record everything, but it's not enough. Humans aren't supposed to live this long, and your constantly failing memory is testament to that. You can't keep doing this. You don't even know why.

    You leave yet another city and, on a whim, you climb a mountain.

    You find a strange pit.

    … You jump.

    You don't die, of course. But, with what you find, maybe you can finally live again.

    Summary

    When a little kid asked you for help, telling you their friend was hurt on the mountain, you didn’t ever expect that little shit to push you down the hole where their ‘friends were stuck’.

    What really got you fucked up was the fact that the kid's ‘friends’ really were stuck in the mountain. Now, you were the only human, and you had a very large target on your head with a heavy bounty for your capture.

    And then there was those annoying skeletons that were always on your case. both were menaces to society and a rather large pain in the ass since you ran into them at every turn- even when they weren’t trying to capture you, they were hanging around you and bickering.

    Well. Maybe they grow on you a little...but its not your fault you were fated to be apart of their lives! blame that weird goop man that told you what 'the universe wanted'.

    Summary

    It has been a month since Frisk freed everyone from the Underground. Everyone is happy and enjoying life on the surface…. well almost everyone. Frisk is depressed and disappears at 2 pm in the afternoon, it used to be only once a week now it is every day. Toriel is of course worried and asked Sans to follow Frisk to see what they are doing by themselves. Sans of course agreed to go but for a different reason….

    Summary

    A human girl thinks she's ending her life when she throws herself down a crack on Mt Ebott but is found and healed by the skeleton brothers. It soon becomes clear that she might be a much anticipated priestess who has the power to summon the beast god that can free monsters from the underground. She must travel through timelines and alternate universes to find her guardians, skeleton monsters with strong souls who will aid her in her quest to break the barrier and maker her dreams come true.

    Fushigi Yuugi/Undertale hybrid fic written purely for readers wish fulfillment and reverse harem fantasies! ;) Gonna try to keep it pg 13 but I might do nsfw ficlets and short stories based on what if scenarios.

    Summary

    In the dog days of summer, a happy event sparks a terrible realization in Toriel. One she had been neglecting to give focus during the time she and her family had spent adjusting thus far to their new life on the surface. In light of their freedom, her immortality would be little more than a curse as she watched those she loved grow old around her, while she remained as she was forever.

    She knows there is only one way for her to age again, to avoid such a fate. But things are no longer as simple as they were over a century ago.

    Summary

    HI GUYS.
    So to be super honest, this is a redo of my very first Underfell fanfic found here! https://archiveofourown.org/works/5098739/chapters/11727857
    I've changed a lot as a person but I always thought back to this story in particular because I never gave it a concrete ending.
    Some parts of the story are going to be rewritten so please read this new redo instead of the original content.
    You as the reader and Frisk are gender neutral; and use they/them pronouns. You are given the name Mars as a nickname, from an existing name of Marshall and Marceline!

    ALSO I SHOULD NOTE THAT I'M DOING IT HERE BECAUSE I HAVE LONG FORGOTTEN THE PASSWORD TO THAT ACCOUNT. PLEASE FORGIVE ME IF YOU HAVE BEEN WAITING FOR ME.

    For this series, it's a monster harem! But there will be specific chapters for you to enjoy with your monster boyfriend.

    I really hope for your support and that I will have enough determination to finish this story!

    Summary

    Follow along as a collection of extremely creative and horny individuals chat about this monstrosity of an AU, born from the mention of a strange kink and snowballing from there ;)

    ~~~

    The Bad Sanses lived a fairly easy life despite being the infamous scourges of the multiverse. Battling against Ink and Dream, they fought to spread negativity and pain while maintaining a rather love soaked existence in the safety of Nightmare's castle.

    That is until two of their rival Star Sanses show up at their door, begging for sanctuary as their bones tell the story of their abuse. Now that they think about it, it had been a while since they'd seen Blue and Dream on the battle field...

    Just what exactly had Ink done this time?

    Summary

    Something went... Wrong. We don't know what caused it but it took us from our homes. Our families. Our universes. It was only by luck that we found each other- and by chance that we made it this far. I can't be sure how long we have. To my last dying breath, I will fight...
    I will get them home.

    Summary

    This story was inspired by Tastysins_tm, please go check them out!

    Monsters used to be feared in stories, believed to be real by children and adults of old. They were left alone and they would leave others alone, until they weren’t. It’s been centuries that humans and monsters knew of each other, but the relationships between the two has never been good. Now they were being called creatures, lab experiments for the unlucky, and friends to the fortunate. There has been new monsters that emerged and they maybe they will have better luck than you and the other unlucky creatures of old.

    Summary

    A collection of writing prompts for Undertale, primarily the AUs. I made this book because I have a lot of ideas for writing, but I have zero motivation to write any of these ideas out, so I thought I could at least share them.

    None of the scenarios/prompts inside are directly linked to any smut. However, there will be some prompts that have specified relationships, hence why I put the Sans/Sans tag for relationships. I admit with those ones I will be being biased towards some of my personal favorites when it comes to ships, but if you choose to use one of the prompts then you can always change out the characters.

    No credit is needed. However, if you do write a fanfic or oneshot using one of the prompts, I'd love for you to let me know so I could check it out! I don't know how to link fics though.

    Tags will be updated with time. They're, uh, a mess as you can see. I will also warn all of you now that I'm very bad at titles, so don't be surprised when you see the titles.

    Summary

    He should be dead. The mugger was going to kill Sans for his audacity to be broke like nearly every other working class gal or gent in Ebbot City. But then HE intervened. A young nursing student by the name of Papyrus. Sans wasn't expecting anyone to help him. Especially not a fellow skeleton monster.

    And just like that, with one good deed, Sans' life is once more turned up on its head. As they say, the path to hell is paved with good intentions.
