Once she tells her worries to her closest friend, Sans, they develop an idea to stop the nightmares once and for all: return to the monster world and retrieve flowey in hopes that Alphys can return him back into his real self.

    Summary

    You are a Forensic Psychologist and Activist with the newly formed Monster Rights Group; People for the Rights and Equality of Monsters; PREM for short. After the Barrier fell, monsters were incarcerated by the government, and freed by the public through a vote. Even through freedom, however, the monsters weren't safe. Many went missing, and even with PREM's efforts to make their lives better, the monsters were still afraid. After coming out of a kill-or-be-killed environment, it was hard to rattle their cages. And yet, they were fearful.

    The Devil's Backbone, where monsters are bought, sold, and fought like dogs in the pit.

    Reader Discretion is Advised, heavy shit going on in here.

    First chapter is short for set up.

    Summary

    Long ago human kind waged war on monster kind

    Threatening the extinction of Monster kind, we took to the caverns of MT. Ebott.

    The humans rushed to seal us away from them out of fear and ignorance.

    After a century, a human fell into our hollows. They showed us peace, patience, and love.

    Our prophesy was fulfilled by a simple child, they freed us from our dark foreboding confines.

    They broke the barrier and guided us out with promise of friendship, compassion, and acceptance.

    They lied.
    ~~~~~~
    Ten years after the barrier broke. Hell has broken loose and no one is safe.

    One girl.
    One group.
    Can they save both races?

    Summary

    So when I finished this amazing anime called Magical Girl Spec-Ops Asuka

    I had a thought that was boiling in my mind of how that could work.
    Which in Undertale the scene of Undyne saying that anime is real question came to mind.
    I was like well eeehhh heck why not lol

    So I was thinking to make Alphys and Undyne theory true in this Fanfic of this character got sucked into
    Their world when a the multi dimensional being magical girl caused a rip portal when she was battling.

    Yea ill roll with that XD

    Summary

    An old professor of yours always said insanity was doing the same thing over and over and expecting a different result. You'd been trying not to think about it for seven years. Still, you pulled out your hair in clumps and slept with furniture pressed against the door. In a last ditch attempt to not be useless, you threw yourself into your university work, and by dumb luck found a subject that interested you and a lab partner who didn't care you slept in the office four nights of the week.

    A bachelors and a masters later, a letter comes in the post offering a research opportunity and a chance to shed your old skin. Looking to disappear, you accept, but what's done in the dark will always be brought into the light eventually.

    Whether you're ready or not is a completely different question.

    Summary

    Marrying at twenty and divorcing at twenty-two doesn't exactly leave the best image of you. Adopting a seven-year-old child during the short length of your marriage only made that worse. Now, it's time for you to move on, though you find it hard to do so.

    It isn't until you come across a city bustling with human and monster folk alike that things begin to change, the change leading you to meet new faces – both kind and unkind.

    It's then that you realize that – sometimes – what you really need is a moment of repose. You find yourself in the need to simmer down and for your mind to clear as a consequence.

    You're able to find that place the further you spend time in your new home. There, you form brand new relationships with monsters you never thought could exist – one of them in particular making you relive things you once thought were long lost.

    A save point – as you chose to call it – was something both him and you were in need of.

    The following story is a re-write of the first UT fanfic I ever managed to publish on the Internet.

    Summary

    It's literally been two years since you got your head out of your ass and started acting like an adult. One of those two years, monsters reappeared on the surface after the barrier on Mt. Ebott broke. This is a story of how you suck at adapting to social situations, fail at creating a proper environment for yourself, and continue to be an absolute social nightmare in the face of all adversity. This is also a story of how you overcome all that, and find a family waiting for you on the other end of it all.
    Government ruling the job market via soul value, and the occasional stab at your bad art of a plant. Welcome to adult life in a literal hell, kiddo. Strap yourself in. It's gonna get hella bumpy.

    Summary

    You're a...
    Well, to be honest, you aren't much of anything. Your life after your sister's disappearance was a depressive episode wrapped in one big bad life choice, and even though there's a tiny glimmer of hope that you'll dig yourself out of the rut you're in, where would you be then?
    One last score with the gang, you tell yourself, and then you're out. With your mage abilities it's a cinch, right?

    At least, it should have been. But one misstep lands you in the lap of a skeleton monster that's kinder and more broken than he looks, and it isn't long before you're navigating the road to recovery together, and helping each other see yourselves in a new light.

    (Swapfell version of my other story Fight Me! because why not. Stories run independently and you won't need to read the other to understand this, but it has fun easter eggs throughout for those who have!)

    Summary

    Moving to a whole new city wasn’t exactly your plan, but the thought of driving hours to get to a college everyday wasn’t something you wanted to do either.

    You didn’t know that simply moving into the city would turn your invisible world around.

    Hey...why are they acting like that...?

    Summary

    A fairly self-indulgent fic about post-pacifist Mettaton growing a bit too accustomed to human food with the help of his human personal assistant.

    There may be force feeding later on, as well as dubious consent in the form of characters contributing to feeding without their goals (kinks) being fully known. I do not plan on rape in the form of intercourse. This is just to give people a heads up to the consent/lackthereof that may be contained later on--obviously, each chapter will be tagged appropriately.

    Summary

    You're first in line to welcome the monsters to the Surface. Integration goes surprisingly smoothly, considering the mass exodus from Mt Ebott. Though many humans are skeptical at best, you find yourself drawn to this charismatic lot of Underground dwellers. Some are endearing, some are funny, and others make you want to drop your panties in public--but all of them seem to treat you differently than the other humans.

    Perhaps they sense in you a kindred spirit. After all, you've never really felt at home among your own kind. Perhaps moving in with your new friends can be a positive change.

    As long as you can try to keep your hands to yourself long enough to make sane decisions.

    Ah--who are you kidding? You are so majorly fucked.
