    Summary

    Frisk, the adopted daughter of Queen Toriel, thought she would never find her soulmate. She would be single forever like her two siblings, Asriel and Chara. Sans knew he had a soulmate, He has felt their soul. He has no idea who they are though.
    Until that one eventful day.
    ~~
    Undyne, in shock, threw one of her many spears in the direction of the sound that had startled her.
    Papyrus gasped as a small human used her soulmates magic to block the spear. Papyrus started rambling about how that was his brother's magic. Undyne apologized to the short human getting a decent look at her. The Human had rolled into a bunch of golden flowers.
    She had short brown hair that cupped her face in a bob. She was wearing a knitted blue pullover sweater with two purple stripes in the middle, the sweater was too big on her as it exposed one of her collarbones. The distance between the end of her fingers and the end of the sleeve was enormous, at least a good two inches.
    Papyrus introduced himself to the human, asking her over to meet his brother. Her so-called soulmate.

    Summary

    Long ago, a child ventured to the mountains with a goal to find the monsters that had been locked away underneath. They succeed but are met with a new obstacle...the world above has changed.

    A skeleton monster, who has never seen the sky and lived his life in hopes of seeing it with his sibling and friends one day, finds himself seeing the sunrise for the first time. Yet, must find a way to survive in a world that is harsher and straight out of a horror movie.

    A girl from the surface faces horrors that wish to devour her at any cost. Yet, she manages to persevere and lives day to day with help of a gun and something inside her that is as old as the ground itself...magic.

    Life on the surface is not how it should be. it's wild, the buildings are ruined and slowly being taken over by nature, and danger lurks around every corner, but the humans who live here are determined to battle and rid the world of these horrific creatures and their master- no matter the cost.

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    Summary

    Sans is the most famous sky pirate out there. Though, he's not the type of pirate you would expect. Yes, he robs, raids, and has an undoubtably shaky relationship with the king and the Royal Sky Guard, but he also protects the islands from the one thing everyone fears most: Black magic.
    Magic has been around for centuries, and it's what keeps the sky ships running, and the islands from crashing down onto the now desolate and barren earth.
    It can't be destroyed by anything.
    That is, anything except for black magic, and the beings who wield it.
    But so far, Sans has managed to keep it out.
    Suddenly, everything starts to fall apart. Sans' girlfriend, Frisk, the master Blacksmith, has been kidnapped, along with many other blacksmiths from many different islands.
    Without them, magic begins to dwindle, and the entire sky world is in danger.
    It's now up to a crew of pirates, a banished prisoner, and the captain of the Sky Guard himself to set things back to normal.
    Will Sans be able to rescue the love of his life, and the world he fought so hard to protect?
    Or will he be forced to choose just one?

    Summary

    Instead of the wizards being faceless powerful beings capable of trapping the monster under the barrier who are never brought up again. What if they were remorseful people forced into servitude and the barrier wasn't a punishment but a last ditch effort to protect the monster instead?

    Summary

    You have a past.

    Of course, everyone does, but yours isn't particularly nice. Not that anyone else will EVER know that.

    Between studying hard for an Art Major, being an author, being one of the largest activists for monster civil rights, and keeping your rather nosy monster friends out of your love life, you have a lot on your mind to keep you from thinking about what you've been through. Your SOUL is rather private, and that irritates a certain skeletal friend of yours.

    But when you reluctantly agree to help your two favorite scientists out with a soul-related experiment at their work place, you accidentally make a connection to The Void... And bring the father of your two skeleton roommates back in the process through very unconventional means.

    Welp.

    Summary

    Hello ladies and gentlemen. I'm your dear author Freddy. My aim with this AU is to take a comical approach to something regarded as disgusting. If you are looking for a serious undertale Au i suggest you look elsewhere.

    Long Ago humans and monsters lived peacefully together on earth. That is until the humans realized the taste of monster was actually quite delicious. The monsters were chased underground by the hungry humans. The monsters fearing the humans locked themselves under a barrier hoping for a day when a human would fall and save them.

    Frisk is a average chubby kid who loves food and finds their way to the mountain falling to a world of monsters that are living food. Can Frisk control their hunger and save the monsters without eating a soul?

    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.
