Welcome to the crazy world of UNDERTALE, where it's a game where the protagonist is a child that fell in a stupid mountain full of dorky monsters, secrets, and two skeletons, one being a spaghetti-lover human-hunting fanatic, and the other being a lazy plump smiley trashbag with a big heart, and really low stats but initiates a crazy battle in the middle of judgement. UNDERTALE SPOILERS AHEAD. Proceed with caution. Toby Fox may hit on you. I know right. **** Please remember that UT does not belong to me, 'kay? The dog mentioned above owns it.

Reader insert. What if W.D Gaster didn't just get split between time and space, but actually ended up in your world in an abandoned hospital you called home? Your were a young child he decided to use as experiments to test human determination in said world and breaks physical laws to test human possibility? He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.

Endless possibilities (Underfell Sans x Gender Neutral Reader)*BEING REWRITTEN!* by glossedweed

Word has been released that monsters now roamed the surface, and you can't help but feel slightly skeptical. You had been told since childhood that monsters were vile and repulsive creatures who wanted nothing more but human blood pouring from the palm of their hand. You didn't know what to think of the monster race, but majority of the human race did. The tension between monsters and human kind was sickening. People had told you to stay away from monsters at all costs. But that'll be a bit difficult when two skeleton brothers move in next door to you. And why bother lying? You can't deny that one of them has stuck on your mind. (Warning. There's a lot of colourful language, so just a heads up. And also, the artwork doesn't belong to me. Credits to the rightful owner.)

Won't You Stay My Little Honeybun? by Krembell

You were the assistant to Alphys, her co-worker tinkered on a very curious machine in the same department you worked at, incidentally that co-worker was your chosen soulmate. His name? Sans, Sans the skeleton. You didn't really spend any time with him or rather he was purposefully avoiding you, knowing that he also knew you were soulmates tethered by a soulmate connection. The only reason he allowed you to be around was mostly because of your ability to put things into your memory with excellent accuracy to remember important things like a certain blueprint or a recipe for medicinal use. You had tried multiple times to befriend Sans but everytime he looked quite uncomfortable so you stopped trying to force him into a friendly relationship. One night you had been left alone with the curious machine as you had leftover work to do and one event led to another. You wish you hadn't cut the string.

Colletta had felt stifled in her friend's house. It wasn't that the house was tiny, rather it was the occupants that were stifling. Although her friend's boyfriends were skeletal monsters, she never minded that they were monsters. It was their actions that made her feel unwelcome. She had never done anything but act as a respectful tenant. When she left, more skeletons appeared as her life became a trainwreck. Old and new faces all come to ruin her peaceful life. The skeletons in her closet came bursting down the door when she didn't want them to. As each of her dark secrets becomes uncovered, she can't help, but think if she made the right wish. Warning: There will be uncomfortable topics such as abuse, violence, gore, mentions of rape, human experimentations, mental instability, terrible writing, etc. If you are uncomfortable with heavy topics, please leave. I do not wish to bring mental anguish on you. Started in: 2/20/24 Ending in: N/A
