    Summary

    It was nearly sunset, rays of sunlight showing brilliantly through the window. Dust particles floated in the light, flying through the air as you opened the door to the laundry room. The room was warm, cluttered, and dim, as the only light source was the window, and it was already sunset. You walk in, and are greeted by the most delicious looking berries you've ever seen. Or is that just your monkey brain talking?

    (Sans catches you pondering the nature of Tide Pods™ in the laundry room)

    Critics call it "KINDA UNFUNNY FOR WHAT'S SUPPOSED TO BE A JOKE FIC, YEAH?"

    Summary

    Happy 3rd Anniversary, Undertale!

    After over 2000 resets, and watching his little brother die yet again, Sans finally snaps. His new choices lead to the barrier breaking and him assuming control of monsters. However, by absorbing the Red Soul and Chara's hatred, Sans becomes a ruthless dictator after almost single-handedly winning the war against humanity.
    Over 50 years pass, and Sans is still in command, respected and feared by monsters and humans. Humans have become slaves - treated well so long as they obey - and a new species has been born. They have been officially called Mongrels, and they are the offspring of human mages and monsters. All mages are eliminated, and Mongrels are sent to orphanages to learn to live in society with low level jobs to keep them under control.
    However, one day Sans stumbles upon a group of monster teens beating up a female mongrel they kidnapped specifically to abuse before handing over to the Royal Guard as a 'runaway' and immediately takes the abused girl in, much to the shock and dismay of the rest of the world. For someone who has been so ruthless, it makes no sense. But the world will soon realize that the mongrel, Raina is the key to Sans returning to his true self.

    Summary

    The thing didn't come back.
    But someone else fell.

     

    This is a sort-of-but-not-quite sequel to my first fanfic, "Dust in the Wind, Sunshine on your Hands", working by the same premise that Sans loses it after Papyrus dies on a genocide run.

    Summary

    Word of Asgore making the decision to expand his territory had traveled quickly among the many mob clans in Ebott City, despite his assurances of it being “completely diplomatic” and “entirely consensual between bosses” with “appropriate compensation.” G had been skeptical of the goat monster’s decision, but when Asgore had approached him about providing a watchful eye over him on the upcoming inaugural ball, he hadn’t hesitated in accepting the job. Asgore was an old friend, after all, and who was G to refuse him?
    So G had ordered several of his most trusted executives to attend the gala as “volunteered security”, along with several of Asgore’s own soldiers. G himself had known he would to attend, but…he hadn’t expected that his human would’ve wanted to tag along.

    Alternate summary: There's been a death threat and G makes sure that no one gets hurt. Well, no one too terribly important...

    Gaster!Sans belongs to borurou, Mafiatale to nyublackneko [I think].)

    Summary

    You're the lucky one to end up stuck in an underground world amassed by monsters of all sizes and calibers. But one of them is different from the rest, in more than just one way. And maybe he too, can sense a little difference in you. Why else would he have chosen to kidnap you instead of kill you? Why else would he employ you as his maid instead of dragging you off to King Asgore to be slaughtered?

    Oh yeah, and you're having bad dreams riddled with yellow flowers almost every night.
