    Summary

    Life in Swapfell can make even the most patient monsters frustrated, angry even. Except for Razz, he gets downright murderous. But that's not so bad when someone else is begging for you to break their bones.

    Summary

    Summary

    "when can I go home?" although all the affection they immediately felt for Toriel, Frisk had places to go, and a person that they wanted to see again… maybe weren't that nice as the places and friends they met, but are their true home (translation of "Lugares a los cuales ir")

    Summary

    “Xeno felt his monsters crawling on his back; demons pounding in his head. The agonizing throbbing in his mind was devouring his sanity alive. He needed to escape. There was no way he could survive like this.”

    Dealing with his past’s trauma, Xeno, a person from another universe, finds himself stuck in the Underground with broken wings and without the ability to use his Saikik powers. Meanwhile, his close “friend with benefits” Ravina-Wolf Kigami, King of Tooikuka, starts searching the multiverse for his friend. However, during his time in the Underground, it seems that Xeno’s presence has really changed things for the monsters who live there...

    Summary

    “Goodbye,” I whispered, with a small wave. Seeing her standing there, her hands clasped in front of her, shedding silent tears, made me want to turn back, made me want to make it okay, but I couldn’t.

    I turned, and pushed open the heavy doors. There was a ramp, leading upwards, towards another set of beautiful columns. I took a deep breath, and ventured forward. Step by step, I made it to the next set of columns. It was dark.

    Here goes nothing.

    I took the final step out of the Ruins, and my foot crunched on something white and cold.

    “Oh, come on!” I shouted at no one.

    I hated snow more than anything in the world.

    Summary

    This is a human AU. Humans are trapped Underground, and monsters are on the surface. Our beloved characters from Undertale who were monsters are humans in this AU, and the humans are now monsters.

    Sans. is a young adult who needs a job, and Gaster is the one to give it to him. The Royal Scientist has no idea why he hires someone so under qualified to help him run a science facility, but nonetheless, Sans now works under him as his assistant. He has no plans to become friends with Sans whatsoever; but, fate doesn't care about plans.

    THIS IS A REWRITE!! If you're new to my writing, I highly suggest you read this instead of the old one, as it is, in my opinion, put together much more coherently. If you're not new, well, I've been told by a couple of you that you reread the original several times, so I highly doubt you have any issue with reading this rewrite.

    Either way, with all that said, please enjoy.

    Summary

    At the young age of seventeen, you didn't know what to do when you had a child. You didn't know what to do when your family disowned you and threw you out, nor what to do when you moved in with your abusive boyfriend.

    But when your child, merely five years old, vanishes from your life, you put a stop to it. You left behind the disgusting man that dared harm you and started anew, pulling yourself together. A new job, a new apartment, a new mindset.

    And with monsters coming into the world, you find yourself enjoying their company...until you spot a certain monster holding hands with a very familiar person and your entire world goes into chaos.

     

    ...You knew they were still alive.

    Summary

    The Chaos Theory states that any tiny changes in any equation, has many different consequences and situations.

    You were that change. Your very existence has made the Underground a better place overall.

    But when you finally get to the surface, you have to deal with tiny shifts in time, caused by the current Master of Time.

    Like it is said. Any change can give way to bigger changes.

    Summary

    After changing her major from business to physics, Avery meets some interesting characters in her science class. Befriending a group of monsters wasn't really in her college plans, but she can't help falling in love with all of them. Well, almost all of them. As much as she enjoys her new friends, Avery notices that something feels... off.

     Updates every Wednesday!

    (This was originally going to be a Sans/Reader fic, but I despise writing in the second person. You'll love Avery though I promise she's fun.)

    Summary

    Reset. The power to alter fate.

    Determination. The power to overcome any obstacle.

    These are powers awoken only in the most determined of humans. And it is these powers that set this story into motion.

    Two separate lives, seemingly by happenstance, become tied together in ways none could have foreseen. Two separate stories, once having nothing to do with each other, become bound by strings even stronger than fate. And yet, as the darkness deepens and past tragedies are shed in new and revealing lights, these two sides may be the only thing that can stop a brewing plot that will lead to calamity.

    But perhaps, with just enough determination, not only may the world be saved . . . but the souls of those left behind might find salvation as well.

    Once upon a time humans and monsters went to war.

    Once upon a time humans lost.

    Once upon a more recent time Papyrus' brother Sans got a promotion. And now Papyrus was off to buy him a human. His new lord only deserved the best and with that he brought home what most would have deemed the worst.....

    And Sans couldn't have asked for anything more.

    Fighting was her only grace in a world where she was never the one in control. But now faced with these two new adversaries... even that may be torn away from her. Just like everything else she has tried to keep and protect.
