    Summary

    Everyone's heard the story time and time again: A human falls into the Underground. A kindly goat man adopts a child and they live in peace until everything goes wrong. Suddenly Frisk is on a tale of way too many reloads and resets as they try to find a way to just live in peace, but in this kill or be killed world, how long until they become a killer too? (hint, not very).

    Don't let the Ruins fool you, this is still a Fell-world. I don't know how dark it'll go (expect the rating to maybe be bumped up to M), but there's going to be a good deal of death. Albeit there's resets so some of it is pretty temporary.

    This AU is a swap!fell!AU, but it is not Swapfell or Fellswap. This AU has my own personal touches and a bit of a universal quirk that you'll have to read to find out about, but isn't overrelied on or anything.

    Anyways, I hope you guys enjoy. Tell me if there's any tags I'm missing, if I need to change the rating, etc. I'll add tags as they come up.

     

    I'm too lazy to change old chapters, but if I ever get to new ones, hopefully there'll be a bump in quality. Ya get better as you go, y'know? Maybe if people are super interested, I'll fix up old chapters.

    Summary

    You fell. And what a stupid fall it was. After all that time, all that determination, all your Hope. Nothing even mattered because you fell. And now you’re dead. Or, at the very least, close to it. You can still feel pain, which you suspect is something that dead people don’t usually feel. All you can do for now is keep your eyes closed and hope for the best, be it death or salvation.

    Summary

    You died. Simple as that. You lived what you think was a pretty normal life (not that you really remember), but you did die. How did you know you died? Well, that's because your SOUL was reincarnated into the body of a baby skeleton, with strange memories that you don't remember experiencing, about something called the Surface, in a strange lab with a strange skeleton (monster? man?) named Wing Dings Gaster who tells you that you were created specifically to destroy.
    'Destroy what?' you may ask yourself.
    Well.... You aren’t going to like the answer.

    Hiatus for now

    Summary

    So um… I’m doing this because I want to and I got a fifth follower on Twitter. This is for her. Plus I keep thinking up AU’s and I’m not doing anything with them so I made a reward for myself. I make an undertale AU fanfic every five followers on Twitter (granted I might do one regardless if I’m motivated enough). *WARNING this AU HAS ZERO RELATION TO XTALE, UNDERVERSE, OR UNDERCROSS*. This a role change based AU. I’ll put a link to my Twitter in the End Notes of every chapter.

    Summary

    If there was one thing that the you of your childhood and the you of your young adult life had in common, is that you had an unfailing belief in the unbelievable.

    Most people wouldn't have bothered to look into the truth of the Legend of Mount Ebott, but your grandmother's stories told a tale that seemed believable.

    And it turned out she was right.

    But unlike most tales, the journey for that "Happy" ending will take a little bit of patience, kindness, perseverance, a lot of bravery, integrity, a fierce sense of justice...and maybe a bit of determination, to make it happen. But that's okay, because with the friends-- and enemies-- you make, you're gonna need it.

    After all, most stories with magic and monsters turned out well in the end.

    ...right?

    Summary

    AU: Underswap

     
    I tightend my grip around the dusty orange hoodie, taking a deep breath to calm myself when I heard footsteps. A child, dressed in yellow and green, with short, brown hair, red eyes from too much Determination, brown boots, a knife and clothes covered in dust, entered the room. They can't know. They can't. I repeat my text, my lines, perfectly out of memory, like I always do. But as I look Chara in the eyes, I can't help but ask.

    (Не судите по названию, мне просто понравилась игра слов.)

     

    Т/Ц - твой цвет.
    Т/Ц/В - твой цвет волос

     

    Ты модифицированный гибрид, выращенный в неволе, в вольере для Ламий. Ты- ламия человека. Таких в природе не существует. Есть только скелеты - Ламии. У тебя (т/ц) чешуя на хвосте с красивым (т/ц) брюшком. Твоя особенность в том, что на кончике твоего хвоста есть погремушка, как у гремучих змей, но тебе самой её не сделает. И однажды, в соседний с твоим вольером, поселили дикого Нага.

    Что ты собираешься делать?

    Summary

    *Updated Summary* You're 23 years old, you dream of being a famous Lyricist-singer-songwrighter. You begrudgingly go to MEU a local college with your best friend and almost immediately flirt with a certain skeleton and then develop a magnetic attraction to a professor, Dr. Gaster. He's the 'enigma of MEU' but that's not surprising since you have a thing for tall-dark and brooding types. It is surprising that he's willing to hear you out, then offers to trade lust for your submission, with a deal you can't refuse. When you find out your very soul is at risk of being claimed by the void and only Gaster can save you, you're only further motivated to stay with him. Along the way you start to fall hard, you want him to be apart of your dreams for the future. Gaster has finally met his magnum opus, his obsession, your anomaly of an existence. A bright soul covered in betrayal lines. However, you've awoken something in him he thought permanently dormant, something he'd been suppressing for eons since his specific monster species had been particularly dangerous. You easily shattered the wall of control he had built over thousands of years, can he succeed in keeping you alive or will he just end up being the cause of your demise?

    Summary

    It's been twelve years since she first fell into the Underground, but Frisk can't stop returning. Each Reset, she is more eager to return. Less willing to Reset again. But that's how things have to be, right? Even if she's aging, and the Voice in her head is getting stronger. Even though her short moments on the Surface are getting tougher...
    But this year is different. Everyone else seems to be remembering something too. And there's more than one monster in the shadows who's gotten sick of watching the same show. Frisk soon finds out that just doing a Pacifist run won't be enough for a happy ending...
    What happens when the OTHER angel decides not to follow the script?

    Spoiler Alert: This fic will ruin the events of the Undertale game--it's 100% a game worth playing and experiencing blind.

    Note: This fic doesn't take into consideration anything that happens in Deltarune.
