    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

    Sans likes to play a lot of video games. A lot. He’s a gamer, hands down. Dead by Daylight is one of his favorites. Meg Thomas is his go to survivor. And so what if people assume he’s a girl? Sans doesn’t mind, sometimes guys even give him free stuff. She has good perks, and free items is never something to shrug at.

    Gaster, lonely after years of science, took up the offer Alphys said and decided to try some video games. And he sucks at it. However, one Meg Thomas named ‘Sukeruton’ extends a helping hand when Gaster desperately needed it.

    Now, he’s in love. With someone he believes is a girl.

    Sans accidently catfished the Royal Scientist of all monsters. And he was not prepared.

    Summary

    The screen filled with the image of Gaster's face. It was in portrait mode, like a cell phone video.

    "You really thought you could take him from me, did you?" The Gaster on the screen asked with a wide, self satisfied smile. The camera panned around, and there was little Sans. Shorty.

    "No, no, it can't be," Gaster whispered as Sans quietly cursed beside him.

    ~~~

    S01 was doing well. He's rescued. He's happy.

    Dr. Gaster wants him back.

    Fuck you Gaster.

    Summary

    Gaster has always forced S-01 to be quiet, no matter how much he's hurting his experiment. Years stuck in a remote-controlled shock collar have ensured that S-01 won't make the tiniest whimper no matter how much pain he's in, physically or emotionally.

    Gaster just wants to *make sure* that's the case.

    Summary

    You pass away abruptly, and you manage to lose everything.
    Then you're thrusted into another body, into another life.
    You become Sans, yet something is wrong. It isn't fun, thrilling nor what you dreamed of. It is war torn, violent, unforgiving and everything goes wrong. Papyrus hates you.

    Then from war you end up in a basement face to face with better alternates. Your memory is hazy and LV high, how will you deal with papyrus ignoring you, and the weight of your sins? How will you control yourself?
    You won't be able to hide from your alternates for long, and they're strangely pushy. Life seems to hate you, doesn't it?

    Summary

    Error finally did. He finally found a way to end it all. Finally found a way to get out of Fate's grasp once and for all. After so many years of nothing but pain it shouldn't have shocked anyone, much less Fate, when he destroyed his own SOUL without hesitation. Dying with a happy grin on his face.

    The moment his SOUL shattered was the moment the balance was truly broken. Fate could only scream while something inside of Destiny broke.

    Knowing that something needed to be done, Fate reached out into other Multiverses, looking for a SOUL to replace Error's. A destroyer is needed no matter what. Making or forming a new one could just make things worse and would take too much time.

    When Fate found the SOUL, Destiny decided then and there that she was done playing nice and safe.

    The SOUL Fate found on the other hand, was done before she even woke up in a new body. If Fate thought she was going to play by any kind of rules, much less listen to him, then the joke was on him. Aiden doesn't forgive easily and she never forgets. She carves her own life even if it's with blood on her hands.

    It only takes Fate a few hours at most to see that he truly picked the wrong SOUL for the job.
