    Summary

    “ENOUGH OF THIS NONSENSE”, 'Papyrus' mutters as he grasps at her snarling maw, narrowly dodging the snap of her fangs. “THIS WAS OVER BEFORE IT STARTED.”

    Despite the burgeoning loss of sensation, she eyes him balefully from the ground full of defiance. Toriel rises slowly but surely, every motion holding promises of a fight he'd never forget should he come close.

    “Like hell, whelp.”

    Gaster blinks.

    Well.

    This was new.

    Anyway, the Barrier is finally broken (for the last time), and the Monsters are happy for the future

    But who's to say that the other humans won't be nice, and force all of your progress to Reset?

    Summary

    In the underground, the story will always be set straight, no matter how many times new elements force their way in. Like a game of telephone, how many times can a story be re-told, and how long will someone be able to remember the first telling...? Outside the barrier, how long will monsters remain a devilish myth?

    Summary

    Once upon a time, a human fell into the Underground. Chara poisoned herself and her brother Asriel used her soul to cross the barrier. But, in the end, their plan failed and it took the lives of six more humans for the monsters to finally go free.

    ...But what if Chara survived, and the other humans fell to find a world that welcomed them? Perhaps freedom without bloodshed is a possibility after all.

    Summary

    When Chara and Flowey find themselves in a familiar-unfamiliar Underground, where everyone’s happy, the air doesn’t taste like dust, the royal children are still alive, and the Royal Scientist is someone they’ve never even heard of before, they have no idea how to handle the strange world they’ve found themselves in or what happened to the one they know. Sans, on the other hand, knows exactly what he’s going to do.

    In which time travel is either going to save the day or end it, Chara is incredibly confused, Gaster is a worried dad, the Great Papyrus is very great, and Alphys is the stuttering voice of reason. Also, the past version of Sans gets to see just how much of a face-heel turn he ends up making, and it’s just business as usual for the future one.

    Set a little bit after Punchline in my Underfell timeline, but you shouldn’t have to read it first. (You totally should, though.)

    Summary

    Can something smell golden?

    You wake up in a bed of flowers in the middle of a cave, without any clue how you got there or really anything else. All you know is that your legs hurt and you can't remember anything and there's a talking flower and you're getting serious deja vu.

    Summary

    It should go without saying by now that this is a species swap AU (alternate universe), but in case you're new to my work, I use my own human AU. Monsters are on the surface, humans are Underground. Humans still started the war, but they bit off more than they could chew and the monsters locked them down there with a magical barrier. Ya know, typical Undertale stuff, just flipped on its head a little. Our beloved characters from Undertale are now humans, Frisk, Chara, and the other fallen are monsters, obviously.

    Summary

    = = = > DAVE: Notice the Door opening behind you.

    What?

    The thing that you hear next is a small creak coming from the Door that you just so happen to be standing in front of, back to it so that you can watch all of your friends. Terezi is the first one to notice something, probably sniffing it out with that keen snout of hers, and before long Rose’s head snaps towards your direction too, eyes slowly widening as she let go of Kanaya’s hand, using it to latch onto one needlewand as the other raises to point.

    You think that she says something, maybe something along the lines of, “Behind you!” but you don’t get the chance to see it clearly. As your head turns, you catch a glimpse of a black mass there, one with a white face. You have no time to react. And even if you did, what the hell would you do? This is something from the universe that you all created- this is one of your creations, technically, and it’s apparently strong enough to open up this literal Door to the Void.

    You have no time to react as a skeletal hand clamps over your mouth and drags you back, through the Door.

    Summary

    The barrier's broken, monsterkind is finally free, and Dr. Gaster is reunited with his two wonderful sons. You'd think everything would be smooth sailing from here on out, but there's one little, teeny,tiny complication the skeleton family has to deal with: the consequences of one missing night after the worst week of Sans's entire life. Fortunately Sans has the support of his friends and family in these trying times. Now if only he could figure out who the father is.

    Summary

    This is a human AU. Humans are trapped Underground, and monsters are on the surface. Our beloved characters from Undertale who were monsters are humans in this AU, and the humans are now monsters.

    Sans. is a young adult who needs a job, and Gaster is the one to give it to him. The Royal Scientist has no idea why he hires someone so under qualified to help him run a science facility, but nonetheless, Sans now works under him as his assistant. He has no plans to become friends with Sans whatsoever; but, fate doesn't care about plans.

    THIS IS A REWRITE!! If you're new to my writing, I highly suggest you read this instead of the old one, as it is, in my opinion, put together much more coherently. If you're not new, well, I've been told by a couple of you that you reread the original several times, so I highly doubt you have any issue with reading this rewrite.

    Either way, with all that said, please enjoy.

    Summary

    The city has fallen. Food and magic are in short supply and a killer gang roams the streets looking for victims and basically rule what is left of the ruined city. Three factions (UT, US, UF) are all that can stand against them and try and protect what's left of the population. The UF faction may be a bit resistant to a truce but considering the fact that one of it's members is in love with the leader of the UT faction, they really won't have a choice.

    Summary

    Dancer 213 was raised in a lab, filled with cruelty, and with no idea about her true identity. She was always taught that monsters needed to be sealed in the Danger Zone for the good of humankind, even at the torture of their children. But as she grew into a young woman, she soon realized the monsters might not be as dangerous as the captors led on.

    I do not claim to own the original game nor its many AUs; as such Flowerfell and Echotale, or other AUs are mentioned, but this plot and possible original characters/AU belong to me. Any famous songs, TV show/movies/books and manga names, and brands that are mentioned in this work belong to their rightful owners. This is purely for fun and my inner fangirl.
