    Summary

    "Sans, leave. You can't fix me, you can't do anything about anything, can you?" They yelled, flinging the knife around wildly while gesturing.

    His eyelights shrunk significantly, and his smile tightened. "Nozomi, put the knife down. Please."

     

    Formerly the mess that was Bad Day (the old version), I bring you an angsty, self-indulgent fic. I hope you enjoy this as much as I enjoyed making it! Updates every two weeks (roughly), feel free to yell at me if not.

    The human children had committed Genocide for the last time. W. D. Gaster is sick of this, seeing them do this over and over. It's time for something, something new, something unpredictable... Maybe time for additional cast.

    Summary

    He should be dead. The mugger was going to kill Sans for his audacity to be broke like nearly every other working class gal or gent in Ebbot City. But then HE intervened. A young nursing student by the name of Papyrus. Sans wasn't expecting anyone to help him. Especially not a fellow skeleton monster.

    And just like that, with one good deed, Sans' life is once more turned up on its head. As they say, the path to hell is paved with good intentions.

    Summary

    You know, coming home to multiple versions of your housemates from alternate realities really shouldn't be a surprise at this point with their track record. You could count the number of times you thought to yourself "I'll be gone for a while but what's the worst that can happen?" only to find the answer later and saying "Oh, that, okay."

    But, you didn't mind, they were your best friends. And so were these ones, they were just from different planes of reality and didn't know it yet, so you didn't mind them staying too much. So what if you thought they were cute and wanted to kiss them?

    Summary

    Mooktale is an AU that takes place in a dead timeline, untouchable by a "Player" presence. No humans fell past Chara, and the Golden Flower Experiment never took place. Instead, before his mysterious disappearance, W.D. Gaster created an experimental monster and implanted his own magic into them.

    Now, the new Royal Scientists (plus an optimistic Assistant) must take care of this monster, in a world where memories are fickle and family is more than names.

    Summary

    You didn't know what eating those people could do to you. You didn't know how falling into the underground would change you. You can't bring yourself to regret it, either way.

     

    Or, I wanted to read a fic where; Sans and Reader were already in a relationship with none of that waffling back and forth nonsense, surface monsters exist and reader is one of them, Horrortale Sans and Papyrus healing, and Reader becoming a Wendigo via eating humans and exposure to magic. This sort of popped into existence.

    Summary

    The daughter of Herobrine, Diamond, and her annoying devil on her shoulder, Sapphire, fall into the underground. What happens when the genocidal creature in her head decides she’s unsatisfied by the pacifist ending and wants to play with everyone too?

    This is part 1 of 3. Part 1 is exactly like the game, the pacifist route. Hopefully Diamond and Sapphire’s interaction will make it worth reading.

    Part 2 will be the genocide route.

    Part 3 will be the true pacifist route.
