    Summary

    A scorpion asks a frog to carry him over a river. The frog is afraid of being stung, but the scorpion argues that if it did so, both would sink and the scorpion would drown. The frog then agrees, but midway across the river the scorpion does indeed sting the frog, dooming them both. When asked why, the scorpion answers, "I couldn't help it. It's my nature."

    Summary

    This is an added on part to the work titled “Disgusting,” by Interverse. You do need to read that story in order to understand this one. It is my own interpretation of what might happen, following the events of the one shot. I did use a bit of inspiration from a comment made by the original author, Interverse, on their own story, which detailed what they believed might happen afterwards. Consider this a gift to you, Interverse, for creating such amazing works with all kinds of awesome ships. Keep writing, broski <3.

    Summary

    I have noticed a dire lack of dedicated Alphys/Reader content on this site, and I come here to fix the problem myself. Suggestions/Requests, on the off chance that anyone has any, are welcome, be they smutty, fluffy, fluffy and smutty, AU, or any combination of the previous.
    Reader characters will generally have a penis, seeing as this whole thing is very self indulgent.
    Individual chapters may or may not be connected.

    Summary

    Inquisitive [/ɪnˈkwɪzɪtɪv/]
    [adj.] having or showing an interest in learning things; curious.

    Curiosity always change something in our life

    Usually, it leads to something good.

    For example, Frisk's curiosity about the tale lead them to Underground and meet monsters.
    Ink's curiosity leads to the born of multiple AU.

    However, Curiosity also can lead to a dangerous road.

    For example, Frisk's curiosity about the reset awake Chara's conscious
    And Ink's curiosity leads to Error's existence.

     

    This story was inspired by ' Healing what has been broken ' by harrish6 but, instead of Error went to the Void, he stays in his Multiverse. And there's a consequence because of this.

    (A/N:
    Error! Forced God of Destroyer belongs to @harrish6
    This story is about Error become (forced) God of Destroyer while Ink become The Creator, the one who creates AU

For a full year, willing human and monster participants would live in an enclosed society together to not only test if the two species could live together but to also see if magic had any lasting effects on the human participants. Your life wasn't really great so deciding fuck it you sign up to room with two such monsters for the year.

    Summary

    Though it might sound exciting and fantastic at first, a hero society is not always just fun and jokes. The people that don't get the chance to be a hero get left behind, forgotten and abused by an economy that is crueler than any villain. And the people that try to simply help and better the world are treated as criminals compared to those that get paid to do so.

    The Judge is an unregistered hero, hunted by the police for nothing but trying to help and save people, though that never stopped them from helping for no pay, out of the pure good of their soul. Unbeknownst to them, they've grown a much bigger following in fans than they would've ever expected, though not even that will help them with their own personal problems and the growing hostility of the government, police and legal hero towards them.

    The Red Revolution is working to try and make things better, working against the government to support illegal 'heroes' that help without a license and to help the normal people in things that fall forgotten to the government. And sometimes that includes taking in and helping an innocent little skeleton, seeming to be crushed by the growing burden of his cruel job.
