    Summary

    Monsters return to the surface. Frisk returns to the custody of the only family member that's ever actually wanted them around, their maternal grandfather, and starts to recover from the life they lived before they came to the Underground. As everyone tries to figure out how to navigate and coexist in this new environment, it becomes clear that this is going to be a long, complicated journey towards coexistence. It won't be easy, but it can be done... assuming no one has any dark secrets that might end up making this any more complex than it needs to be.

    Summary

    Disoriented and emotionally frayed from decades spent in the void, W.D Gaster suddenly finds himself at the mercy of a cold and arrogant alternate self. His doppelganger promises to return him to the void once his research is complete but before he can make good on his threat, Gaster is introduced to this world’s variant of his son and he is forced to make a quick, spur of the moment decision.

    This sole act sends unforeseen ripples throughout the Multiverse and hurdles Gaster on a perilous journey across it to find his way home.

    or

    Dadster plays hopscotch across the multiverse, unintentionally and intentionally acquires children, tentatively reciprocates Grillby's feelings, engages in actual literal custody battles with copies of himself, somehow steals a Bad Sans™, narrowly avoids death at the hands of Error and somehow flies under Ink’s radar for a shocking amount of time.

    Summary

    A butterfly beats its wings and all that.

    Sometimes, the most important events may be set into motion by the tiniest thing. Some decisions cannot be planned beforehand.

    Life is never predictable. Science isn't either. You do the math.

    Summary

    Legends say never climb Mt. Ebott. Those who brave the trail are never heard from again. Well, you were never one to put much stock in a children's story, anyway. Besides, who could resist the beautiful scenery? The leaves have just turned and it's the perfect weather for camping. Frisk will probably enjoy it too.

    As luck would have it, those stories weren't just fantasy, and what should have been a tragic accident turns into a grand adventure of fallen humans, a family, and Determination.

    Welcome to the Underground.

    Summary

    Just when you though you were finally settling into your life in the Underground, life throws you for a loop. Now there is a dead scientist who never existed inside your head, you're seeing strange Monsters that you have never seen before, and a soulless flower child is hellbent on killing you and taking your Soul.

    Sounds like a normal Monday morning. At least you have Frisk and your Monster family to support you.

    Summary

    (Inspired by this plot bunny by askellie . Link contains spoilers, but there will be massive changes, especially for the ending.)

    In the Underground, it’s not just kill or be killed. It’s…Own or be Owned.

    Weaker monsters can be protected if they are willingly (or unwillingly) publicly claimed by stronger monsters, giving them a way to survive in a cruel and unforgiving world.

    Orphans Sans and Papyrus struggle to keep themselves alive, despite Sans' unparalleled power making him one of the most feared monsters in the Underground at the tender age of 13. But his baby brother wasn't so lucky. Instead, he was gifted a rare innocence and compassion for all life. Still, in a world where kindness is weakness, and weakness gets you killed ...or worse, Sans will have to do the unthinkable in order to keep him safe.

    Summary

    1000 resets. 1000 Genocide runs. The human tried to reset once more but something went wrong.

    Resetting farther back than ever before a set of twins fall into the underground.

    Years later during one of Flowey's many runs he stumbles upon an abandoned lab and a babybones. There's something about her he just cant put his finger on. Something familiar.

    Meanwhile all the monsters of the underground are beginning to remember previous resets, slowly losing their hope and going mad. In this world of violence it won't end well. It's up to Flowey and the skeleton household to fix things but it wont be easy, especially now they have their own demons to face.

    Summary

    After the humans came to the surface many didn't have any place to go. So the government set up a program. Anyone that could take in a human would. This is how I met the Skeleton brothers.

    I've never been more content. They are the best thing that has ever happened to me. So... When a bunch of male skeletons suddenly appeared. I... Wasn't exactly sure what to do. Especially when I slowly began to fall for them.

    I'm in deep trouble...

    Summary

    You love Undertale it really stood out to you. Kind of like how you stand out to everyone around you.

    You live alone in a small cottage in the woods. Your only company is your loyal companion Joey, a german shepherd the only living being you see. Besides your clients of course.

    You were still lonely sometimes even with Joey.

    (Well what do you expect when your family moves all around the United states, and when you look like well, you.)

    That is until one day you and Joey were on a walk and one thing lead to another Joey was showing you a weird looking UFO machine ( is what you thought it was at first)

     

    "Funny, wouldn't this be cool if this lead to Undertale, hah in my dreams."  You start to walk away when flash of light caught your eye.

    All you hear is Joey barking before everything goes dark....
