    Summary

    (Y/N) (L/N) was once an icon; an absolute icon to the masses. But destroyed out of jealousy, she is given a new chance with a brand new power and is thrown right smack dab in the pre-main plot of Undertale, where everything hasn't gone to shit yet from Frisk's meddling.

    And she'll be damned to let these poor souls rot beneath ground, not when she has the power to stop it.

    And dammit all, she WILL persevere and achieve her goal!

    ...

    Now if only she wasn't so damn attached to Flowey.

    Summary

    After a while on the surface, the monster race wakes up to the Underground one day. To put it shortly, it sucks.

    In which the horribleness of a post-pacifist reset are explored, one where EVERYONE remembers.

    Edit: Due to the feedback among a small yet interested group of readers, I'm going to tack on a second part as another chapter.

    Summary

    One day, a strange phenomenon rips through the Ebott Valley Area a few years after the Surfacing. People vanished. Not just physically, but all evidence of their existence in people's memories and physical photos are torn away too. Like they never existed in the first place.
    Families are left without mothers, fathers, children at the table, and nobody stops to question what they don't remember.
    All that is left of the people that vanished are these cocoons that later hatching into small colourful creatures; somehow neither human nor monster. They can speak from the get-go and they have basic reasoning, but almost no knowledge of the world outside the care center they're placed in.

    And then there's one singing along to Bohemian Rhapsody.

    Summary

    Amazing. You'd gotten this far without being seen by monsters, avoiding very confrontation with minimal suspicion only to be captured in your sleep. Your captor, the infamous royal scientist Dr W D Gaster, had been keeping you in his lab for tests. Why he didn't just kill you and cart your soul off to Asgore, you didn't know. All you knew was that the only one that went in and out was Gaster and apart from two other skeleton monsters, you were alone. You'd get out one day, right? For now you just had to persevere. It was in your nature, after all.

    Summary

    We know very little about Error's past. He couldn't have always been the Destroyer, right? Where did he come from? Was he always a glitchy mess, or was he forced into that by Fate? Will he be able to forge his own Destiny? If you want to know the answers, or at least my version, read on.

    This is a story of an AU nearly as old as Underswap and Underfell, that has been hidden from the rest of the Multiverse. This is the story of Error learning about who he was before he was the Destroyer. This is the story of Error making his own Destiny, after centuries of being trapped by Fate. This is the story of Error and Startale.

    Oh, and a dog of course. You can't have Undertale without dogs!

    Summary

    Sans has never hated anything more than his own damn SOUL now. Chara, on the other hand, is hardly disappointed with her new toy. Now all that's left is to train him. Wouldn't all that power be lovely to use against the monsters? Or, better yet, the surface? Sans is pretty far gone, but he's not that weak so as to do her dirty work. Especially not if his friends… if his family’s lives are on the line. Still, he’d do anything for Papyrus...

    Summary

    Sometimes a family is a snarky fire elemental, an overworked skeleton scientist, and a baby grown in a jar.

    Living in the Underground has never been easy for anyone and hope is hard to come by, but whatever happens they’ll have each other in the end.

    Summary

    The first time Castiel brought Gabriel to Sam Winchester's bed, it was out of desperation. As the Archangel slowly recovered from his captivity at Metatron's hands, the reasons for his continued return to Sam became less practical and more personal with the runaway Archangel and the Boy With The Demon Blood learning to heal each other.

    Summary

    Una sola vitae, una sola mors.

    Monsters have been trapped for hundreds of years within Mt. Ebott.
    Their lives are inextricably tied to those of humans...but exactly how has been lost to time.

    ((Updates will be sporadic due to my terrible health. Please be patient!))

    !!! Characters' speech relies heavily on fonts, so make sure you have comic sans, papyrus, determination, wingdings, and aster installed on your compy if you want to see things the way I've intended.
    FYI: I'm using ao3's public Undertale work skin. :)

    Summary

    Somehow, he gets the feeling that this situation isn’t covered in any of the handbooks. Everything else could at least vaguely be explained by some kind of jutsu, whether Gen or Nin, but this...

    He didn’t think that there was any kind of Jutsu that could affect the way Gravity applied to you. And the grin that had once seemed friendly on the small skeleton’s face now seemed to be rather ominous. He gulps and struggles a bit in the grip on an unseen force.

    “heya pal. talk like that makes it seem like you're looking for a B a d T i m e."

    Summary

    There are eight fallen children who survived the fall. There are seven fallen children who didn't survive the Underground. There is one human child who saved everyone and broke the barrier.
    (There is one human child who died in a field of golden flowers and lived once more in a scientist's lab.)

    Everyone deserves to have their side of the story told.

    Summary

    The one where a grad student lucks into the best Study Abroad program of all time, learns magic, plays poker with dogs, develops a really confusing crush on a man made of actual fire, and at some point should probably write her thesis.

    Set one year after the end of the game.

    You may enjoy this fic if you like: painstakingly mapped out lore, development of magic systems, expansions on the culture of the underground and the characters therein, and dicks made of fire.

    Summary

    My new story is here http://royalroadl.com/fiction/chapter/105878

    Or you can read my dropped story if you want

     

    This is a different Frisk then you are used to. She isn’t some angel, although she once was. This is a Frisk that gave into the power of resetting. The feeling of gaining strength was addicting.

    Unknown to her someone remembers. Sans grew tired of standing idle and started hunting Frisk. Time lost all meaning, was is a hundred years, was it a thousand.

    However after a long enough time Frisk gave up and got the good ending.

    It’s been six months since the barrier has been broken and things are going pretty well.

    However Frisk and Sans are having a hard time putting their past behind them. but who could blame them. After all, hundreds years of Frisk killing everyone is hard to just leave behind.

    It doesn’t help that they are living under the same roof as legally adopted siblings.

    As every ones past is revealed will they stay united or will everything they worked for fall apart
