    Summary

    They could fool Asgore with fake hugs.

    They could fool Toriel with fake innocence.

    They could fool your brother with fake promises of friendship.

    But they cannot fool you.

    You'll never forget who really hides behind those masks.

    You'll never forget what they have done, all the suffering they caused.

     

    But that's all you can do right?

    No matter how angry you are, you will always be useless.

    Summary

    Most Post-Pacifist AU fics are simple. Humans are bad and monsters are good. Human prejudice is a minor obstacle to be overcome with a few cheesy speeches. But not this time, for the monsters of Mount Ebott have entered a larger world with different values and different people. And while humans are flawed, what did monsters do to deserve such a pedestal, anyway?

    Trope Page that I got chewed out for making, because even though you're NOT allowed to recommend your own fanfics, you ARE allowed to make Trope Pages for your own works: https://tvtropes.org/pmwiki/pmwiki.php/Fanfic/TheWorldOfHumansAndMonsters

    Summary

    Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.

    This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.

    Summary

    I discovered the PTA Sans AU on Tumblr and now it won't let me go. So here you have it:

    Little shorts placed in the AU where Sans adopted Frisk together with Toriel, Toriel is running the local school and Sans was roped into going to the PTA meetings.

    Let's just say that he gains a lot of motivation during those.

    (Now with plot: A secret project between two nerds, an ongoing inspection and the insanity that comes with monsters living together with humans.)

    Summary

    When Sans first found the jacket, blue barely visible through the grime, he knew it would take a lot of effort to fix. The strings were frayed at the end, the knot impossible for his skeletal hands to untie, and some of the seams were pulling apart. He knew it would be a good coat if he could find a way to fix it but he wasn't all that good at sewing and didn't want to ruin it. If Papyrus hadn't been the one to insist he kept it, Sans would've left it there or given it to someone else. 

    Oh well, he sighed. What harm could another project do?

    Summary

    Your name is Frisk.

    You were only eight years old when you fell into the Underground the first time. That... undertale.... became the subject of your dreams (and nightmares) for many years to come. Twelve years later, you went back to Mt. Ebott to try to see if you had imagined the whole thing, as the psychiatrists all tried to tell you.

    Then, you fall again.

    Silly, clumsy you.

    Nothing is the same down here. You'll find that out soon enough.

    Summary

    Sans was used to the endless cycles, the repetition had become his cage and his comfort. He knew what would happen, he didn’t need to be worried for changes.

    But one aches for what they don’t have, and those who would choose safety over freedom deserve neither.

    And Secrets, Especially bigs ones don’t stay secret for long.
    //Or the main monsters find out about the resets, and after everything Sans and Frisk (+Chara and Flowey) aren’t okay with that after all.

    -Frisk and Chara use they/them but you can imagine them as any gender you want.
    -Sans has depression but he’s not suicidal. He doesn’t wanna die and I’m tired of seeing the stereotypes of people who self diagnosed.

    Summary

    Toriel wants Frisk to see a doctor. Sans thinks she should maybe not worry so much.

    Frisk wants to not see a doctor. Toriel thinks that they should be a little more concerned for their health.

    Sans mostly wants Frisk to not wander off and climb some other mountain and fall and die in a hole somewhere where nobody knows where they are and unravel the timeline and-

    ...and Alphys thinks a whole lot of things.

    Summary

    All monsters had wings. They were an extension of the soul, an important part of their lives, each set unique to every monster. Just because most couldn't often use them to fly Underground didn't mean they didn't use them at all. Whether it was fighting, flying, or just to express themselves and their emotions, most monsters loved to show them off.

    Most monsters.

    Sans doesn't show his wings. No one had really questioned him before, but now, on the Surface for the last time, he made a promise to his brother. He isn't one to break a promise.
