    Summary

    When nine skeletons awaken in a strange room with vague instructions to watch Creator-made videos about one another, nobody was quite sure what to expect. Leaving that place as a family had certainly not been the plan.

    OR

    Nine Sanses watch animatics about one another, though not everyone there will have videos about them.

    Summary


    He skidded to an unsteady halt as he finally got a close look at the two passed out Skeletons.

    “What the fuck?”

    Blue didn’t swear often, but this? This definitely merited it.

    Summary

    Hunger was a primal thing. A way for the body to urge the brain to seek out nutrition. At some point, between the beginnings of starvation and the threat of death, the body will take over where the brain refuses. Even if death is not applicable to the body in question, hunger will always prevail over weak things like morals.

    Basically, I make Dream suffer a lot because I want him to break and then have to be put together :)

    No, I will not take criticism. And yes, his suffering will be long and arduous, and he will refuse help at absolutely every turn. What else is he supposed to do?

    Summary

    Disclaimers:
    Several details in this fic are heavily inspired by 'Blue joins the bad sanses' comic, so go check that out
    Canon innacuracies: Passive and Corrupted Nightmare are the same person, Ink is the creator and not the protector, Ink, Error, Nightmare, and Dream, are all gods, Blue, Killer, Horror, and Dust's specific au timelines were all destroyed, and i took liberties with how the void works. Also, no Cross sans will be mentioned, i don't know enough about underverse, and there will be some OC non-sans God/entity/things later on. The fic will be split into parts, each lasting nine chapters.
    Schedule: Once a week, on Saturday, Sunday, or Monday, and i will post art or a reference sheet with every chapter. Trigger warnings will be specified in chapter notes. I've never written for undertale before, so please let me know what you guys think :3

    With that said, the actual plot: After an injured Error crashes into Nightmare and Co's home, a close bond starts to form between the two gods, both forced villains. In light of Ink's attempt to kill Error, Dream finally starts to lose it, and Blue gets dragged along.

    Average chapter length is 500-2000

    Summary

    This is a human Afterdeath werewolf au. The main ship is Afterdeath. But there is some implied Science x Geno, Errink, Cream, Kreme, ScienRed, Dustberry, Crossmare, Killermare Horror x Dust at some point. This is a slow burn, but it will eventually have smut.

    Warnings: This first chapter has extreme violence and torture in the beginning, including some implied non-con. There will likely be death and other forms of violence throughout the story.

     

    Fully covered in a black cloak. Everything around him seemed like darkness and death, just like the masked man. He could only see his mouth, which was unexpressive. He looks almost ancient. Frisk trembled slightly, bowing to him while Geno could only stare slightly before avoiding his eyes and walking past. The cloaked man stopped.

    "You're looking better." The man's voice was deep and almost soothing, at least to him. They continued to walk, and Frisk glanced at him as they continued on their way. They walked in silence until the others were out of earshot.

    "Who was that?" He asked, and she trembled slightly.

    "H-he-" she cleared her throat, "he's the judge, and…he was the one who found you."

    Summary

    Remember the times you joked about "dying for your fictional crushes"?

    Well, one chronically online, strawberry patterned pajama-clad Bad Sanses fangirl actually did—courtesy of a pixelated meme dog and what might be the universe's worst case of writer's block. Now, she's stuck in the Undertale multiverse with nothing but her AU knowledge, a deeply unserious System guide named Selene, and the terrifying realization that her beloved skeletons don't blush on first meeting.

    They try to murder her.

    Armed with terrible skeleton puns, niche references, and a soul that might be powered by sheer cringe, her new mission is clear: befriend the murderous skeletons, grind enough EXP to not die (again), and somehow stop the multiverse from collapsing-all while convincing a glitchy skeleton that she's not the weirdest thing he's seen today. (She is.)

    It's a self-insert isekai where the only thing stronger than Determination is a fangirl's ability to ignore red flags.

    [ I curse ao3 and its limited description. Uploaded this on Wattpad and Quotev as well! More active over there, this is my first released fic here :) ]

    Summary

    The title says it all. IDK if this is appropriate to post this. Hopefully this is ok.

    Anywho, this is about ideas I like to share because I highly doubt I'll ever write them. I super duper enjoy the fan fiction side of the fandom and hope this is taken well.

    There is no set update schedule. Just random posting. Comments are welcome and I'll try to reply to them all.

    Summary

    The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.

    Within this realm, Dreamtale exists as an enigma, plucked from another Multiverse entirely. The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.

    Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.

    Nightmare woke up freshly dead.

    Au: Get it? Cuzhe died lmao

    Summary

    My hatred grows, my determination intensifies. The dust surrounding me is insignificant compared to my rage toward the human. "I regret nothing," I say before unleashing my fury.

    But then, Chara's words haunt me.
    "Feeling something new, huh? I want to try again."

    Summary

    Hello!

    In honor of Underverse 0.8 part 1 coming out and Jakei’s year and a half hiatus, I am going to (try to) do this thing I will be calling “Weekly Underverse” where I update weekly with some sort of Underverse related content.

    It’s not going to be anything big. Some weeks it will be a 3,000 word Cross fic, maybe a digital drawing I worked on for 5 hours. Other weeks might be as small as a snippet of a poem that was inspired by an Underverse thing, or a little doodle I did in my notes packet. It may even be recycled content I have posted outside of this project.

    But whatever it is, I will try to update it weekly until the hiatus is over.

     

    Weekly Underverse starts today, November 20, 2024. Updates will (try to) be every Wednesday.

    Underverse belongs to: Jael Peñaloza

    Little note: I am nowhere near an Underverse expert, so most things might be fanon, most things might be Cross focused, but maybe I’ll do some learning and write with the other characters. Maybe I’ll give fun facts one week. We’ve got about 78 chances so… we’ll see where this goes!

    Summary

    Dream took everything from him.

    His castle, his magic, his power, and now, as chance would have it, his luck.

    The scream that leaves him is like nothing he's ever heard before, the pain unbearable and unending. The metal teeth of the bear trap dig into his leg and he isn't sure how much longer he can take it. He needs to get out, to keep moving, lest Dream find him in such a pitiful state.

    A savior comes out of the forest, although most would be frightened of him. Nightmare recognizes him. Of course he does. The glowing one eye brings him more comfort than he ever thought possible. He can only hope that he isn't freed from the jaws of the bear trap only to be put back in the maw of Dream and his newfound power.
