    Summary

    The first time it happened you thought it had been a fluke: you’d gone to bed Tuesday night and when you woke it was…Tuesday morning? After the second time you realize something is very, very wrong.
    The cycle continues for months, but just when you’ve all but forgotten what hope feels like, something unexpected happens: Monsters emerge from beneath Mt.Ebott and time begins again as if it never stopped in the first place.

    Barely holding yourself together, you find yourself the servant of lieutenant Papyrus and his brother Sans.

    Summary

    When monsters and humans went to war, the monsters were sealed underground by seven of the most powerful human magicians. Though they wanted to fight back, they lacked the power to do so. The underground has suffered in recent years after the Dreemurr family lost their children. Monsters are starving, violence is common outside of settlements, and the king seldom leaves his throne room. A new human child has fallen underground. They are the 8th human to fall, and the 7th soul to be added to the king's collection. But a certain flower hopes to change their fate...

    Summary

    Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
    It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
    And now, that reason knows about Chara too.

    Summary

    When Papyrus' daughters want something read to them that has princesses in it, Sans chooses the lazy way instead of coming up with a story. He types princess in the timeline machine and straight reads off a Princess Frisk adventure. After a couple of nights, Papyrus leaves and Sans is in charge of the girls. When he reaches the end of the princess adventure, he knows where Papyrus is at.

    He also knows that their timeline is about to be erased, if he doesn't find his own version of Princess Frisk.

    Summary

    Chara’s doing fine. She’s perfectly happy existing only through Frisk. She doesn’t miss having a body of her own. She doesn’t care that her family doesn’t know she’s alive. She’s definitely not making eyes at a certain skeleton Frisk has no interest in. She doesn’t mind being alone and forgotten, not at all, not one bit!

    …yeah, she’s not fooling anybody, is she?

    The truth is, Chara wants to live again. But it’s too late for that now, isn’t it?

    On hiatus until March 11, 2024 or until March 18, 2024, whichever of those deadlines I manage to hit first.

    Summary

    The complete story of Lifetale, an AU of Undertale. Destruction occurs (sometimes), but Frisk can always reset it, so... Additionally, there's a potion that freezes age, hence "Lifetale". All of the monsters, as well as the eight humans, drink it at some point.
    This story has 5 parts: the Introduction, or Prologue, the Genocide run, the Neutral (Pacifist) run, the True Pacifist run, and the Epilogue, or Ending, which is written from Asriel's point of view.

    Summary

    It's been three years since you fell into the underground and found a family among the monsters of the Ruins. You love your life here with Mom, your ghost buddy Blooky, your prickly friend Flowey, and the host of Ruins monsters who have accepted you as their own, but things can't stay this way forever. Your friends deserve to see the sun, and there's a prophecy to be fulfilled and a barrier to be broken. Your determination pulls you onward.

    The only trouble is that you'll have to make it through an underground full of monsters clamoring after the red SOUL in your chest, and each day as circumstances become more dire they lose a little more hope. This is a more desperate underground than the one you landed in. The odds don't look good for one pacifist child with a stick.

    Of course, you aren't completely outmatched. You've spent the last three years training for this moment, and you don't intend to let anyone hit you.

    Summary

    Frisk was overjoyed as they had finally found their true ending. Though, there were a few minor changes to what one might expect. Frisk had developed a deep bond with Toriel and Asgore, even more so than with the other monsters. However, their heart truly belonged to Sans and Papyrus. The conflicting personalities of the brothers had always charmed Frisk, the constant equilibrium of dry puns and enthusiastic banter resonated with them. At first, Sans was unsure if he was ready to take on the role of a parent, but with the encouragement and reassurance of both Papyrus and Toriel, he ultimately decided to give it a try. Toriel, in particular, noted that Frisk had made it through the underground thanks to Sans's protection and even offered to "babysit" Frisk whenever he felt overwhelmed.

    But as with all stories, happiness is fleeting, and conflict between monsters and humanity continued to rage on. Politics and oppression reared their ugly heads, and Frisk's unknown illness added to the inner turmoil they were facing. Will Frisk be able to rise to the challenge?

    Summary

    A complicated tale of a brother moving out of the nest leaving behind he once knew and adjusting to many different situations all while his older sibling battles with depression and self deprecating and destructive thoughts and plans!

     

    Or

    Papyrus and Metteton are getting Married and Sans wants to die!

    Don’t mind the tags guys! This is my first fic on ao3 and I found it appropriate that I should let my old dead undertale phase be showcased first! I just revised it for this upload and it’s late at night so maybe it sucks now! Who knows? Guess you will have to read it and tell me!

    Summary

    "Legend has it, an 'angel' who has seen the surface will descend from above and bring us freedom." Unbeknownst to both human and monsterkind, the term 'angel' dates back to before known history. Before the Barrier was raised, before the war was even a thought in the darkest of the humans and monsters. 'Angels' referred to those rare instances when a human and monster would come together to produce new life - a hybrid of human and monster. Long forgotten by all, there are those among the humans still carrying the potential to inherit these traits. Upon Harry Potter's 16th birthday, he finds himself receiving a creature inheritance of such monumental importance, that he may be the key to peace, between monsters and humans, purebloods and muggleborns, wizards and muggles. And he had always said he simply wanted to be "just Harry".

    Summary

    What happens when a certain human child ends up in hell with nobody with them except the friendly murderous ghost they befriended and their own determination? Will they ever be able to go back home? Or will Frisk, in true pacifist nature, end up befriending these non-humans as always? Stay tuned and lets find out!

     

    (DISCLAIMERS: I'm going to update tags after posting chapters (idk how to do it while posting because I've not written that many fanfictions before, so I'm sorry), a lot of this might not be accurate to the characters (I'm going to try) and the chapters might be short/ infrequent updates, also Frisk and Chara use they/them pronouns)
