    Summary

    How many skeletons does it take to piss you off?

    Just one.

    With him being the supposed representative of judgment for the Underground, you can't understand some of his standards, a few of these two-faced, at their best. After all, how can he preach about being kind and considerate, but disregard the fact his kind made its own fair share of mistakes, him included?

    You don't tolerate his bull, and even less do you humor his attempts at watering down your anger by flirting with you until your temples ache. If he was one of the people involved in letting your child go off on a dangerous journey all on their own, you were far from falling for his tricks. And if anyone's gonna woo someone over first, it's you. Either he falls for you first, or his sorry coccyx can accept defeat and understand you're not an easy one to wrangle.

    No reasonably angry mother is, after all.

    Summary

    As an up-and-coming scientist, you're a firm believer in logic and have always thought the tales of humans and monsters to be myths, a theory you're forced to accept as wrong when these begin to show up at the speakeasy you're a part of.

    It's the not-so roarin' nineteen twenties considering your bleak and overall lowly position in the world. Shifting between jobs as the town's bookworm and a singer for a speakeasy, while dangerous, doesn't bring much conflict or excitement into your life, most of it spent trying to survive and keeping your family afloat. Things take a turn when a gun's pointed at your head, your saviour being a large goatman and his helper a skeleton, both who help you live undercover, unnoticed, and underground.

    Summary

    The balance within the world was now broken, but as with such universal constants it always finds a way to right itself through natural means. A balance of magic and science is required. The humans prior tried to exterminate the existence of magic to no avail. Every death of a mage would bring forth another as the magic buried itself deep into a new soul creating latent abilities in a chosen human child. The Seven: justice, bravery, patience, kindness, perseverance, integrity, and DETERMINATION would live on. If one perished then the magic would attach itself to another chosen soul. The lone town that knew the truth of their past was their only sanctuary. A place for them to escape from those that wished them harm, but absolute power corrupts absolutely and thus this is how our story… begins.

    Frisk clambered up the mountain. The mountain of so many horror stories, myths, and legends. She refused to be frightened by such things, but her heart was still racing as she ascended the peak of Mt. Ebott. It was rumored to be the home of bloodthirsty monsters that were cast into the mountain as punishment for their loss against humanity. It became nothing more than a scary story. Her hands convulsed when she prepared to jump.

    Summary

    Dahlia had finally done it. She was free and on the run, not sure where her life was going from there. The chase takes her to the top of Mt. Ebott where jumping into the void seems the only way she can truly be free. Now she has to masquerade as a monster in order to survive the harsh world of the Underground and enjoy this second chance at life. And the true enjoyment comes from a certain sarcastic skeleton.

    Summary

    Humans lost. Monsters won.
    However, humans are not so easily deterred and beaten.

    Exploring the surface and freeing mankind from their prison to pave the way for even greater heights is a great and noble cause. But why 'Frisk' of all people? And why does our King insist that she leaves with that damn thing?

    Humans are known to always wanting to explore the unknown, no matter how inhospitable and dangerous it may be. It would seem even if the surface was populated with those filthy beasts, our King is willing to take the chance; we don't have much to lose anyway.

    I trust this 'Frisk', the 'determined one' as our King wants us to call her from now on, will be capable of dealing with any character, no matter how unpleasant they may be. Though something in the back of my head is bugging me... Will this young innocent youth ever come back the same from this experience? (updated)

    Summary

    Seeking shelter from a storm, a blind child descends into a realm of monsters. A chance meeting grants him a companion in the form of a ghostly girl garbed in the colors of flowers. Yet, what seems but a simple adventure becomes much more as memories of dark pasts claw their way to the surface. Lives forsaken, a name unspoken... what does this new future hold in store?

    Summary

    I thought I was ready for anything, I thought I understood how to make good decisions, I thought I had the right answer to everything, that I had all the consequences figured out. But the truth was, I had absolutely no clue. Turns out, life isn't like a video game, there is no perfect ending. People don't always get to live, you can't avoid every fight, and the road to hell truly is paved with good intentions. Good intentions don't keep people alive, good intentions don't fill someone's belly, and good intentions are not good actions; all of which I learned the hard way.

    Every decision has a consequence and the biggest decision I made?

    Well, that would be playing Undertale.

    The second was staying DETERMINED.

    That's what let HIM in.

    But, then again, I never would have met Sans. So in the end, I would do it all again.

    ~~~~~~~~~~~~~

    Follow this Undertale player who bite of more than she could chew, as she falls into the very video game she had spent weeks playing. Watch as she fights against Gaster's puppet strings in an attempt to do the right thing.

    Too bad you can't just reload a previous save if things go wrong.

    Despite what that condescending flower says.

    Summary

    Undyne knew that Asgore had been worrying about something for the past few days. He even forgot to chastise her for breaking that ceremonial vase for crying out loud! Still, everything was going great. She'd be joining the guard soon, she'd confess to Alphys, and get the Underground their third soul! That was the plan, at least until Undyne found a pair of brats roaming the castle.

    Summary

    It's been six years since I left, but I can't stay up here any longer. I am not going to let her grow up here with how horrible the people are. I don't care if I can't come back to the surface. I want to go home.

    Summary

    The human always reset. They always do. They always go after his brother. Sans can't let it happen.. not again.
    He would do anything to save his brother.
    Even if it meant giving up his own life

     

    Though, if Papyrus would actually let him die, that's another question..

    Summary

    Set in the 1920's, this fic was heavily inspired by the Mob/Gangster AU's for Undertale.

    Frisk and Chara live a struggling and complicated life on the city streets, having ran away from the orphanage just to survive. With Frisk being the optimistic younger friend, Chara is the brains of their dynamic duo as well as pessimistic, and willing to do whatever it takes to help them survive. The two manage to get by, but it’s on a fateful day that a promise is made, and suddenly the two are separated… by a mobster group known as the Underground, resulting in not just a fight to save their friendship, but a fight to save each other’s lives.
