    Summary

    “You're gonna get in trouble,” you replied through a snicker. He looked amused again, shaking his skull.

    “Nobody's said anything yet,” he said, pausing to glance to the side, then back at you, “Today,” he tacked on, chuckling. “Think I'll be fine. Now, if you'll excuse me...” and he took a very deep inhale from the joint, somehow holding the smoke inside his jaw, despite the wide gaps on the sides.

    Summary

    Em Underswap. Após uma rota genocida do qual Chara não tem lembranças, ela reseta sem a presença de Frisk, porem algo muda nesse reset, e alguns glith´s do destino a levam a um lugar misterioso nunca visitado em resets anteriores. Este local nomeado por ela como “O Lar das Portas”, esse mesmo local é caracterizado por possuir seis portas com cores texturas e formas diferentes, a aventura de Chara se inicia quando sua determinação a leva a atravessar uma das portas.

    Se ela soubesse que naquele momento estaria embarcando numa aventura com novos e velhos amigos, cheia de conflitos, assassinos e genocidas, no qual seus erros do passado a perseguiriam, e onde sua moral e sua determinação discordam em meio as intrigas dos universos ao seu redor, com certeza ela teria recuado... Mas se tivesse, não teríamos essa historia, certo?

    The human was coming back. This killer, wearing the skin of a person. This murderer, bearing the mask of a friend. They were silhouetted against the intense brightness, with their familiar, distant expression, and their knife glinting hazardously at their side.

    Summary

    Cherry's life is the definition of hell. Abandon by the people who should love her, cherish her, and appreciate her. Ever since the moment she was born, she hated everything about her life and herself. Her body, her personality, and her gender. Working in the most dangerous part in the whole city, where she has to keep her guard up very second. You think her life couldn't get any worse? Yet, it did when old flames and a mass murder decided to visit her city. Somehow, she doesn't think this a coincidence.

    Summary

    Sometimes, bad decisions are made. Sometimes, you’re just tired of your family trying to set you up with people. Naturally, it was only a matter of time before you took matters into your own hands.

    What a mistake that was, huh?

    Summary

    Asra was raised by monster hunters. They had their origins in the war that time forgot, when the human-aligned mages locked away the monsters underground...or at least the ones they were able to catch in time. Those who remained went on to earn a place in various local legends, scattering all over the world for their own safety, and largely fading to the realm of myth. This earned her family none too good a reputation in historical circles, as they continued to insist on their version of events.

    When her mother sent her to investigate the Mt. Ebott disappearances, she wasn't expecting to learn that the old stories that ruined her life growing up were true. Now she had a choice to make....

    Summary

    Ebott City, 191X. Fresh from university, Doctor Sans Gaster is ready to become an alienist. He studied hard, knows his facts, but lacks the experience that should go with it. Now working as an apprentice at Ebott City’s lunatic asylum, things are not going as he imagined. For what is insanity? What is madness? What is good? What is evil? Since meeting Frisk, everything he knew changes.

    Summary

    (OR: That One Time There Was a Zombie Apocalypse)

    Alphys created something. Something terrible. And now, it's up to Flowey (with the help of Sans) to save the entire Underground, or die trying.

    This was just a random idea I had, and I haven't finished writing it. I don't know if I'm ever going to get around to finishing it, so I figured that I would post it anyway.

    Summary

    Geno and Reaper, arguably the gayest non-cannon Undertale AU couple, are the main star of this book! Most of these oneshots are typically written just with the classic AU in mind, but occasionally I will throw in some other AUs such as the Fellverse or the soulmate AU, just as an example.
    I can't guarantee I'll update frequently, but as long as I'm in this fandom, I will write.

    Small breaths.

    Numb fingers and shadows.

    Summary

    (Y/n), a high ranking Platoon Commander in the Military, was on a mission with her squad when her plane was shot down by an enemy ship, leaving her stranded on an unknown island, with none of her comrades in sight.

    It would have been all fine an' dandy... if she wasn't surrounded by three Alpha Skeletons and one Omega Skeleton. All of which want to fuck or be fucked by her.

    So now here she is, having to assess her dominance as an “Alpha” to get by with her limbs still attached and her clothes still in one piece. Even if one of them looks like he came straight from Satan's asshole.

    Summary

    "Uh, hey Axe?" Viper called out cautiously. The hunched figure in front of them took a single staggering step forward. Blue grabbed his friend's arm tightly. Something wasn't right. The skeleton monster look more...wrong... than usual.

    Viper cleared his throat and tried again. "Axe? Are you okay over there? We haven't seen you for a few hours." The figure let out an ungodly shriek that sent chills down the boys' spines. Axe might have been strange, but even they could tell was definitely NOT their friend.
