    Summary

    This little skele, a Sans type, is used to taking on whatever title was expected of him. So when the entire multiverse tells him he is a 'Bad Sans' who can really blame him for joining others who fall under this title. That is as long as Nightmare finds him useful. His past titles have left him with a very limited set of skills, knowledge, and expectation. Yet he is willing to give up so much more just to stay.

    First chapter is NSFW, and then there aren't going to be much until maybe in the future. Plenty of triggers so please tread carefully, I am not used to posting for others to read.

    Summary

    One of Dust's experiments turns him and the rest of the gang into cats. Coincidentally, the Star Sanses find their secret hideout and realize they're nowhere to be found. Instead, they realize there are multiple cats inside. Maybe the Bad Sanes are the random cats in Nightmare's castle?

    Summary

    You've taken a liking to Dating Simulators and the versatility that some of them have. One of those Dating Sims happens to be called Amaremania, or Lovemania. It was a darker premise and not the usual take you would expect from a game centered on romance. The allure of getting through the game without romancing is what pulled you to it and so you've tried again and again to reach that ending, challenging yourself to try to beat it through unconventional ways. Unfortunately, your repetitive playthroughs of this game don't go without consequences. An event you hoped was a dream eventually turns into a nightmare when you realize you've been pulled into the world.

    Shortly after, your memories are wiped. Now you wander about this mysterious world trying to escape the darkness it has and the answers to whether this is your reality or not. Will you be able to find the truth?

    Summary

    Souls. They are the very culmination of our being. Every single living person, monster, alien and robot, has a soul. Now imagine if all those souls made up a person or, if I was to be more accurate, a monster. A monster that was never meant to exist. A mistake.

    Summary

    In celebration of receiving 70+ Kudoses from the Undertale crew (and others) for incorrect quotes, I've chosen to write a fic about how Nightmare's Gang came to be!

    This will include jokes from this fic as well; this is a bad description, but that’s fine.

    Feel free to suggest anything I can add to the story such as AU’s or a forth wall breaker.

    Summary

    Error can't, he just can't. ∂̶̣͉͒̈́̉̈́̕ß̸̆∂̶̣͉͒̈́̉̈́̕ß̸̆ is ruining his life. He doesn't want to do this forced job anymore. He can't take it anymore, he just wants everything to be over.

    ∂̶̣͉̯̲̳͒̈́̉̈́̕ß̸̆∂̶̣͉̯̲̳͒̈́̉̈́̕ß̸̆ found out and Error is terrified for what's to come.

    More for the ones he told then for himself.

    Ink realises he's not the only one suffering from ∂̶̣͉͒̈́̉̈́̕ß̸̆∂̶̣͉͒̈́̉̈́̕ß̸̆. He's just as sick as Error is from his forced job. Bad time helping the one he hates because it just got him in trouble.

    ∂̶̣͉̯̲̳͒̈́̉̈́̕ß̸̆∂̶̣͉̯̲̳͒̈́̉̈́̕ß̸̆ will never go easy on him again.

     
    What will they do now?

    Summary

    Cold. It was all you feel, and the only thing you remember ever feeling. It was endless, much like the black abyss you found yourself caught in. You couldn't remember anything from before, only the pitch black and freezing temperatures surrounding you.

    That is, until something, or rather someone, grabs your arm and pulls you out. Your memories come flooding back to you of the past few hours, blue strings wrapping themselves around everything in sight, tearing them to shreds. Everything was destroyed around you, all the people. Everyone and everything, except you.

    You're introduced to a skeletal god of negativity, who hires you to babysit his crew, in exchange for giving you a place to stay. What do you say, (Y/n)?

    Will you agree to work for him, and risk your life trying to stop a group of rambunctious skeletons from killing each other? Or will you wait forever in an endless black void?

    Summary

    I have a lot of random Undertale ideas I want to write, but i want to finish my main fic 'Haunting a reaper in training' first, so I'll just write some here. I'll probably expand some of these stories in the future but if you want to use some of them go ahead. Just let me know so I can read them and credit just in case!

    Warning: there's a lot of random stuff, so there will be ships you may not like. Don't hate. That's all.

    Chapter 7:

    Nightmare and his gang needed to get away from Dream as quickly as possible, but the other was gaining ground. Luckily, Nightmare wasn't above using cheap tactics against his twin.

    Or

    The Dreamtale twins feel physical pleasure at the same time. (Nothing hardcore, it's just a kiss).
