    Summary

    Dr. Wingdin Gaster kept his experiment, 6 (Sans), hidden from the outside world. An unexpected visit from the king forces his secret into the open. This is a story about good intentions, bad mistakes, and the fine line between being a monster and being human.

    Warning: Because this fic seeks to tie up some loose ends of the UT backstory, spoilers abound. Don't read if you haven't finished playing the game through to your heart's content.

    Summary

    As Frisk reread Alphys' note for the fifth time, they wondered just what she could have done that was so disquieting that she couldn't directly confess to everyone.

    But before they could board the elevator and discover for themself, they heard a voice.

    "Darling! Wait!"

    ...

    (The one where Mettaton decides to accompany Frisk through the True Lab.)

    A corrupted timeline. Glitched determination properties. Bi product of a failed plan. Amalgamates no longer possible. Something else. Something worse.

    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.

    Summary

    The True Lab. Maybe Frisk's not as ready for this as they thought they were...

    Suddenly mobility returned to their feet and they tried to gun it out of there, but it was too late. They couldn’t see in the near pitch-black darkness, but they could feel. Icy fingers felt like fire on their skin with a vice grip on their heart. A laugh, haunting, eerie, inhuman, in-monster. This was the Experiment! Its white body melded together and it had 10 faces yet only one hole for a mouth simultaneously. Fear swallowed them whole.

    It seemed easy - just create a few test subjects in a lab and do whatever was necessary to bring down the barrier. But when a human threatened the brothers, suddenly they stopped seeming like subjects...

    Summary

    Chara and Frisk have been coexisting for a while now, neither of them really ever getting what they want, the ending they want, without the other intervening. Reset after reset they've endured, falling into one of two routines depending on who is in control.
    Only it isn't just them enduring these constant loops. When a certain skeleton snaps under the weight of never-ending resets, something Chara hasn't felt for a long time begins to stir. And he isn't about to give into it so easily.
    (THIS IS VERY OLD,,, I'M VERY SORRY)

    Summary

    There is a great divide between scientific research and ethical decisions. Most of what is done for science is horrible, but done for the greater good. What is misunderstood about us is that we’re mad, or psychotic. If our purpose is to do something to make the world a better place, in what way does that make us psychotic? Freedom always comes at a price; it does not matter how big or how small that sacrifice may be.

    W.D. Gaster is a mad scientist. Not that he is mentally insane, but that everything in his life is pulled into his experiments. He is working to allow monster kind to be freed. The problem is, he doesn’t know how to execute his integrity well.

    What we do in this lab… it’s horrific. But only the three of us have experienced how terrible these outcomes can be. One day, we will be free. I know it. That is what my boss always tells me. I still believe it. We just need one successful test. No matter how long it takes, monster kind should never lose hope.

    I don't know why humans are so afraid of monsters. Humans should be educated on how monsters really are. As monsters, we have learned about the greater race. But as humans, they should muster up at least some patience to learn of the lesser kind.
