    Summary

    What did you expect when you had climbed mt.ebbot? A calming picnic? no, but definitely not almost falling to your death. Now, you're alone with your only, and most precious younger sibling, Frisk. Who is the only one in your family who isn't a complete sack of shit. You both did not deny the truth as to why you went up Ebbot that day, but what you could never imagine, is how it would change you and Frisk's life forever, maybe even the entire world.

    This is "We Will Survive" a *very* Plot heavy Undertale fanficion with a eventual Sans x reader romance, or as I've now called it called. WillTale. You are Frisks's older and only sister, and now, what will the underground do with with two human souls?

    Summary

    You wake up, and you don't know where you are. You don't know who you are, or why you're here. You don't know these people...

    And you most certainly don't know who he is.

    There is one thing you do remember, though; and only one thought is clear in your mind:

    Above all else,

    you need to find your sister.

    Summary

    What if Undyne were to suddenly remember the RESETs? Well, not immediately, of course, but slowly, over the course of multiple RESETs.

    She definitely wasn't going to keep quiet about it, and I'm personally basing this story of a what if that appeared in my head due to a random thought about how she has Determination, enough to let her not die/dust for a period of time, but not enough to bleed like Sans does (I head canon Sans to be bleeding Determination in dis -w-;) or remember RESETs. But what if she were to suddenly, slowly but surely, be able to remember the RESETs?

    Summary

    It wasn't fair. Sans had finally saved you, did it the right way without breaking any moral code. And yet, it wasn't enough. So, he decided to play by the rules the world had given him.

    This was his last chance. No more resets, no more redos or loading or saves. It was all up to him.

     

    ...what was so wrong with consuming a couple human souls to save you?

     

    *it's hard to break someone...but it's damn near impossible to put them back together*

    "You'll be the hero of our generation."
    Killer sighed and glared at his boss.
    "Do I get a choice?" The goopy skeleton chuckled.
    "No." Killer tilted his head.
    "Ok then." He replied, stepping forward slightly. "I'll do it then."
    The skeleton standing before him smiled, his smile grew so wide that Killer thought Nightmare was going to split his face open.

    A horrific scream shattered the silence. Everybody looked around to see equally terrified faces. Unlike anybody else in the room, I knew what had occurred. Someone had finally found the body. It made me grin, just a little.

    Summary

    The fallen human had had enough of being messed with. Having their body possessed every time they entered the underground was worse than any nightmare.
