    Summary

    * I thought I had warned you about that guy. “Don’t let him find out ANYTHING about you”, sounds familiar? … Oh, but that’s right! I forgot you NEVER listen. To you it was all just a game after all, wasn’t it?
    * Hee hee hee. Let me give you a little tip then: the Game is a Lie.


    * Echo Flowers repeat what they hear, babbling back and forth to each other until their words become meaningless noise.
    * What used to be the “truth”… soon becomes too distorted to appeal to anything you thought you knew.
    * Never trust a flower. That’s one of the constants of this world.


    After trying everything he could to stop time loops from ruining his life and universe, Sans has finally figured out the truth. As a last resort, he finds out that he has no more choice… but to ask for help.
    May 1st, 2016. Undertale has existed for half a year, and its fandom is raging at its full potential. But then, a Player disappears.

    Summary

    Sans is conflicted by night terrors and vague memories from previous timelines gone wrong. While they're starting to become more vivid, soon he starts to notice deviations from what he's grown accustomed to and Papyrus does something unusual that changes everything.

    With the River Person out of commission, Sans accompanies Grillby on a replenishment run through to New Home, all while wrestling with a feeling he just can't break about his long-time friend. As he gets to know Grillby in a newer light along with some changes that have come up due to past medical abuse, it's becoming more and more apparent that something or someone is interfering...

    Summary

    Failure. Reset. Failure. Reset. Failure. Reset.

    This time, you fall into the Underground weeks before the 'Eighth' Human child arrives. But you’re not a child. And not many monsters expected to see an adult human in the Underground... not even Sans. You definitely aren’t supposed to be here.... or maybe you are? Maybe you’re the anomaly that can finally stop this endless cycle of resets?

    Or maybe you'll just get stuck in it with the rest of them.

     

    The “reader” is technically a young adult (twenties), female OC whose story is told through the second person. This was done to keep the story's POV similar to the game's POV.

Luckily the one time he royally messed up, All Might just so happened to be around to take him in. How will our little bunny deal with such a massive change to his lifestyle? Read to find out!

    (Note: Most of the Undertale crossover will take place in dreams and abilities.)

    "All right, what's wrong Sans?"
    *…wrong?
    "No cheeky question no…"
    *..horrible puns?

    Summary

    Her parents used to go to a campsite all the time when they were kids, but as they grew up, they never found time to go back. Now that they've had a kid and she's grown enough to take care of herself, her parents decided it was time to situate themselves back into the campground, citing their own youthful adventures to their 18-year-old daughter as a reason for their 3-month visit.

    With this in mind, Constance fully expected her summer to be boring, planning accordingly with the things she packed. She did /not/ expect to find herself smitten with the most popular boy at the site, and most certainly never would've guessed that he would eventually return the affection. After a few weeks of flirty passes and a few longing touches, he eventually offers to take her to a place she'll be the first to visit.

    Of course, she goes -- she's young, not stupid.

    Expecting a day of adventure in a nearby town, they instead end up at a cabin in the woods. It was all looking like a perfect romance novel until it took a very horrific turn.

    Will Connie survive these monsters long enough to escape the forest?

    Summary

    His soul is washed over by with a strange feeling. Frustration? Hopelessness?

    Numbness?

    Or is it relief?

     

    In which Red has an existential crisis before turning away from his brother.

    Red is really fucked up in the head. Blame the human.

    Now I’ve think of it, its probably not realization. The poor dude probably has his brain whirring non-stop everyday.

    Summary

    Flowey doesn't deal with loss very well. He hated losing Chara, he hated losing his soul, he hated losing control of the timeline, he hated losing to Frisk over and over. So when he finds something that makes life worth living once again, he will be damned if anything tries to take that away from him.
