    Summary

    In all honesty, the pain should mean nothing, right? Every moment of suffering saved countless lives, so Sans should have no reason to complain, right? His father was doing this out of love… right?

    Seeking shelter from a storm, a blind child descends into a realm of monsters. A chance meeting grants him a companion in the form of a ghostly girl garbed in the colors of flowers.

    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

    Frisk has always thought that he was a normal human, and all of his monster frineds, alongside Chara and Asriel, have thought the same as well. But everything changes on his 16th birthday. Soon, he begins to learn that he's not a normal human as he begins to exhibit actions that aren't entirely such. With a new threat looming over him and his frineds and family, Frisk and company will have to find the truth about himself, and maybe even Chara's as well.

    Summary

    If failed experiments, warped timelines, and emotional family drama weren't trouble already, a seventh human has fallen to tip the balance of fate one way or another. And if one human wasn't bad enough, there may be someone else looking to take a hand in the underground's fate, at least where it concerns a couple of skeletons...

    The continuing of an Alternative Timeline of Zarla's Handplates in which the interference of the Ukagaka Human causes Gaster to reassess his priorities.

    Summary

    Because Deltarune isn't exactly complete, the first chapter is based off one of many endings I thought Deltarune would take. This idea has also been in my head for a while.

    Kris and the Fun Gang have been unable to stop the Angel's Heaven from destroying the world and causing Kris to reload their save. Multiple times, actually. No matter what they did, it wasn't enough. The Angel's Heaven would always destroy them.

    So what happens when The Knight (Gaster) drags The Fun Gang into the void and separates them in another universe.

    One in which the Monsters were sent underground after a war with the humans.

    Now traveling with a small, silent yet flirty child, Kris has to find their friends in a new environment, where everyone they once knew now wanting their soul.

    Welcome to the Underground, Kris. Enjoy your stay.

    As the title suggest. There's not any rules to be honest, just no smut. If you are triggered by anything at all, check the warnings. They will be put in the notes before each chapter.

    Summary

    It hadn't shaken out like she'd hoped, but Alphys was here now, with hopes mounting, and she would make good on it.

    She would make something from it, at least.

    Anything...

    Summary

    3 years after the barrier was broken, Monsters and humans have adapted to live among each other rather quickly, still, with the way human nature goes, not everything was honey and sugar for both sides, some people hate change, and some people can convince even more persons to think the same way.

    But a good thing is that mankind has had time to accept this new way of living, with the social needs being a basic instinct to us humans, the majority of people were happy to accept our new monster friends, though awkward at first, they were proven to be nothing but kind and loving creatures. Still, the subject of magic was something our species had forgotten centuries ago, and, being an ability unknown for the modern era, the government gave them a few rules to keep a track and somehow ‘control’ the way it was used.

    But, even with all the support and story-lessons, there are some things that are best left unknown to us humans.

    Reader is a 22-ish female, characters’ personalities based from the game text/facts trying to be a bit canon in that aspect, but adding some headcanons so the story can be enjoyable too. Also some OC’s may appear. And smut, eventually, but not yet.

    Summary

    "Yeah. We'll free everyone. And with all this time stuff, it'll be like you were never gone."

    "But, be careful, okay? Make sure you come back. Even if it means giving up, stay determined to live, to come back. You're more important than the plan."

    ---

    A long time ago, a human fell into the Ruins. Confused and alone, they called out for help. But nobody came. The human clung to the shadows and hid in the dark. No one knew they were there for a long time. Like a demon, the human crept through the Underground. Until eventually, the human must have arrived at New Home. That's when we found out. Because... Asriel disappeared. No trace of him was left. Not even his dust. And once he was gone, the human left. The kingdom fell into despair. The king and queen lost their child seemingly overnight. The humans had once again taken everything from us. The king decided it was time to end our suffering. Every human who falls down here must die. With enough souls, we can shatter the barrier forever.

    You should be smiling, too. Aren't you excited? Aren't you happy? We're going to be free.

    Summary

    Under sexed tale? Undertale sex? Get it?..

    Who am I kidding? This story is anything but undersexed! Still, it's so hard to find a title for an AU that hasn't already been used more than once. Heck, I'm sure this has been used somewhere too.

    I just don't want to get this confused with something like UnderHerTail.

    It all starts when Frisk finds a 'File Editor' in San's Lab and spends several runs hacking files and editing details... until everything goes 'wrong'.

    There is a plot of some kind in here somewhere. Good luck finding it.

    Summary

    As Frisk reread Alphys' note for the fifth time, they wondered just what she could have done that was so disquieting that she couldn't directly confess to everyone.

    But before they could board the elevator and discover for themselves, they heard a voice.

    "Darling! Wait!"

    ...

    (The one where Mettaton decides to accompany Frisk through the True Lab.)

    Summary

    Dr Alphys, under the pressures of all her failures, finds herself slowly slipping away and losing the will to continue.

    By some twisted miracle, she lives, unsure as to how it was even remotely possible. Clearly someone rescued her, but who?

    And Papyrus won't stop going on about his new friend.

    Alphys, with all her scientific and dating sim knowledge, considered herself well-prepared. But no amount of science and shoujo anime could've prepared her for someone like Undyne.

    Summary

    Life in the city was not for you, so you moved out to the more rural part of your country. It was wonderful. That is until the whole world seemed to come to a standstill at the emergence of monsters and you become wrapped up in all of it. It was worth it. Maybe. The short fake ass skeleton gave you your doubts.

    You decide you hate him.
