    Summary

    She was trying to tell you something,
    She was trying to tell you something important.
    So why can't you remember?

    Now, all you're left with is the memory of Her and the few boxes you were able to recover from the remains of your charred home. Something about the fire, and Her death didn't sit right, and She told you as such. Now, you were going to find out.

    Though, it would be easier to do if the skeleton living in the apartment complex you just moved into left you alone. The way he stared at you made you feel uneasy and... vulnerable.

    Summary

    Sans’ machine brings alternate versions of himself and his brother to their universe in a one-in-a-million chance. Unfortunately, you get flung into the madness when your soul is used as a conduit for the machine. Your soul cannot take the strain, and it inevitably snaps. A month later, while Sans is testing the machine, the machine uses the power of all of the monster souls in the house to bring you to this universe. Trapped in a different universe with a broken soul, you attempt to keep your secrets bottled up. Little do you know; your skeletal roommates have many secrets of their own. Pulled away from everything you’ve ever known, unable to use magic, and your soul broken, you find yourself questioning if all of this will just keep getting worse.

    Summary

    Sans was so in his head that the resets would start back again, he didn't want to even try. Papyrus put in work to convince Sans that he needed to come to the surface with him, and not continue staying in the underground. Sans agreed to pick out a home with his brother, and began packing his things.

    With only a week left, Sans decided to try pulling his older brother back with the machine one last time, only to have to watch it sputter and stop.
    Sans gave up and packed his stuff, ready and moving out to stay with undyne until their new home was bought.
    His life and a few others really went out of whack because of the machines malfunction, with his sudden influx of brothers and the soulmate bonds that were slowly making themselfs known.

    Even after settling the chaos, shit still hits the fan every time he gets done untangling one mess.

    And the woman that is helping his strange family isn't making anything easier by making things easier!

    Summary

    The monsters are free from the underground, but they didn’t all make it. Papyrus, Sans younger brother is dead, leaving Sans to care for the two children he left behind. After a long night of work Sans finally relents and hires a nanny/housekeeper. Enter you, just another human down on her luck and running from her past. This job seemed like an easy way to pass the time and get paid until your past inevitably caught up to you. At least that’s what you thought, until you started developing feelings for the odd skeletons. Now you're having strange dreams, and all these new skeletons keep turning up.

    Can you help them? What is Sans hiding? And what is with this new gaggle of skeletons?

    Summary

    Deep into the city Ebott, just past the entrance trails to the mountain, there is an abandoned house. Though, is it abandon, or just gave up on?

    Most locals of Ebott know of the three-story home with a beautiful Victorian build. The gardens that seem to remain in a constant state of perfection, the vines that creep up walls and through the one broken window out front- said to have been broken during what led to the haunting… Ebott’s very own haunted house.

    That’s where you come in, SPIRIT, you are the haunter of Ebott’s spooky stories and the original crypted before monsters broke to the surface.

    ( based of my {monster?} sona, spirit. but this is an /reader. you don't remember your name or life, so you are just called Spirit. )

    Summary

    You knew the online world held suspicious things. Weird websites, links that led to rabbit holes, the norm. You lived online, never stepping outside unless needed. You shopped online, made friends online, and even made money online. There was almost nothing you didn't do that involved the internet.

    One wrong click led to here though. 'Here' was a world unknown to you, a world that was home to less than friendly people.

    These people, from what you've been...told, aren't good people. Whatever you do, something will bite you in the back later. Whatever happens though, you'll get through this...right?

    Summary

    She said it wasn't an accident.

    She was trying to tell you something important.

    And then she was gone.

    You were left with nothing besides the few boxes of items recovered after the fire had taken your home. Something wasn't right, and you were going to find out what happened to her, why it happened to her, and who did it.

    It would probably be a lot easier if the skeleton in your new apartment complex left you alone. The suspicious look on his face every time he saw you made it increasingly harder to work on your search.

    hello, hey, hi Oki, so you know me by now. If ya haven't already I highly recommend reading Kamisori (Zombietale). even if the story and plots are completely different maybe you can get some sense of (a few) of the character's personalities.

    Zombietale is a really good fic! I love it!

    Summary

    You lived in the lightless depths of the ocean, eating what you could, going where you liked, hunting prey far larger than even yourself. The life of a siren was often incredibly simple, yet undeniably comfortable. You had learned when you were a guppy all about humans. The vile land walkers that could never be trusted. Your parents told you every tale, from kind humans that saved sirens, to horrible hunts where they slaughtered your kin without remorse. You never had a reason to go high enough up for the humans to ever see you, not if you could help it. You would not be prey to the weak land walkers.

    Yet... You cannot truly deny your instincts. Can you?

    Summary

    You were born in space, in one of the many Space Federation orbital colonies. You even spent most of your life in space, rarely stepping foot on actual planets. But you were determined to make the best of your life. You learned the ins and outs of nearly every ship still in circulation, honed your engineering skills to a fine edge. You were going to be the best you could! And maybe... Just maybe, find a place to really call home? Er, well... As long as you can keep within Federation rules.

    With all these skeletons though, this might be harder than you thought.

    Why is nothing working? Something hit the ship?
    You're gonna have to fix all this aren't you...? Here we go again.

    Summary

    It will be a cold day in hell when you let someone else pull your strings, and an even colder one when you let someone else control your city.
    You had more than enough trouble with the human mafia families, now you have to contend with a smart ass monster and his family too? Great.
    It really seemed like Nostra was dead set on making your life as complicated as possible. Heh, 'dead' set.
    Damned skeleton.
