    Summary

    Sans had grown up with those words on his bones. 'That was absolutely HILARIOUS'.

    He would be lying if he said that those words didn't help shape his sense of humor. He couldn't wait to crack the right joke that would let him know that he had found his sarcastic soulmate. If the writing was anything to go by, they were either as genuine as Papyrus, or really sarcastic.

    Either way, he couldn't wait to finally find you.
    ---------
    You had been searching for your soul mate for ages. You had almost given up at this point. You stared at your arm, where the words were written in some lettering that was, honestly, kind of childish. 'i thought it was pretty funny.' You had no idea why all the words were lowercase.

    From what you could tell, he was a joker. That much was obvious, but the case was puzzling. Everyone else you know has proper grammar, at least for the most part. You did run into an upbeat girl who had these weird squiggles after hers.

    Maybe it's for inflection? You weren't really sure.

    Summary

    The Determination human has finally arrived, and Krista is at the front of it all as she battles between paranoia and compassion for the (seemingly) innocent child. But even after the Barrier is broken and monsters return to the Surface, she can't shake her suspicions as past warnings and terrors continue to plague her mind. When time is Reset, Krista desperately fights as another Determination human begins to gain control in search of the world she has always wanted.

    Summary

    You hated every last second of this, being forced to stay undercover as you had to watch the current match in the underground fighting ring you were currently staking out. You wanted to bust in and put a halt to it all, but you couldn't. You had to wait for backup.

    That didn't mean you liked watching those two Beasts fight it out, of course. You winced when the smaller skeletal Beast was knocked into a wall. It was obvious they were both drugged up to the point where their instincts were making them duke it out like rabid animals. But even if they were animals, that didn't mean they had to be treated like this.

    Wait a second, your eyes narrowed, what was that blue glow coming from the skeletal Beast?

    Summary

    The surface was not what Sans thought it would be.

    Lack of communication skills, communication in general, and social interaction had driven him into a depressed and anxious state of loneliness so deep that it'd take a gang of serial killers to help drag him out and fix his problems.

    Literally, it took a gang of murderers called CreepyPasta just to set things right.

    The world acts in funny ways.

    Summary

    They called it a plague.

    At least, the racist ones did. Though it never killed anyone.

    A few of the religious claimed it was some test from God to prove their devotion.

    But the monsters, the original ones that came out of the mountain with the help of their human savior? They knew the truth. It all started with them.

    They called it the Hum.

    Summary

    (Newbie, please don't judge as I also suck at summeries. :D)

    It's been three years since the barrier has broken, and Monsters have settled on the Surface, happily starting their lives without worrying about being sent back. A punny, lazy Skeleton Monster however, worries over the resets, and being sent back into the hell of reliving everything over again. Despite him working constantly, he still wonders if it'll happen.

    Eleanore Rowell, or Ellie for short, lives a quiet life on her own, except for when she has to head over her Father's council. Even then she tends to work a small job at a Café to pass the time, but she's noticed something strange happening to the Dragons in her area and she has no way of stopping it until she finds out who's causing it.

    Summary

    Taken and kidnapped, that's how it all started. We were modified, altered for a sickening curiosity: experimented on. The people who proclaimed themselves as doctors, saviours, said miracle workers of mankind...

    Yet in reality they were the true monsters who walked the Earth. We, the mutants, are the inferior race of humans. Despised. Hated. Feared. We didn't ask for this nor did we want this. Our lives were spent being lab rats, poked at and prodded.

    Like our lives were just merely equal to Toys. Everything was hell, happiness never existed. We could have died, gone insane or just broke entirely, like glass shards from a mirror. Yet, what held us together, kept us strong and alive on the darkest of days and nights was... Undertale.

    Code name:

    Q9. H2. S5.

    Valkie. Noura. Ischa.

    Three girls who manage to escape that hell hole and start a new life, facing with new challenge in lives as their hold faith to each other, as it was fate put in a mere threshold.

    Summary

    Long ago, a human fell into the monster kingdom. They were taken in by the king and queen, and raised by their son. Their deaths sparked grief and rage among the kingdom, and a second war on humans was declared.

    The queen disappeared after the declaration, and was forgotten over time in the ruins of the old kingdom. The Underground fell gradually into dark times where violence was encouraged and rules were expected to be followed without question, ensured by the Royal Guard. Humans fell and died in the name of the war their king led; six human Souls were collected. Generations of monsters passed, waiting for the seventh human who never fell.

    And then, one day, it did.

    Summary

    It has been one month since Kris Dreemurr went missing.

    Waking up from a surreal dream, Susie resolves to comfort her former teacher, Miss Toriel Dreemurr, after the loss of her child. In doing so, Susie discovers something that will shape the course of the world over the coming day.

    Noelle, too, wakes up from a disturbing dream, holding a single phrase with her as she follows Susie through the day.

    For Officer Undyne, the coming day seems typical, but that perception won't remain for long.

    All three continue into their own journeys, twisting and intertwining, as the day progresses, hour by hour.

    Summary

    (Note: This story is going to be rewritten into a newer, better version!)

    You are a very shy individual suffering from social anxiety. However, your bonely life takes a turn for the better when you meet an unlikely friend: a dorky skeleton with a big heart.

    While getting to know the two skeleton brothers, you begin to discover secrets about them; secrets that you probably weren't supposed to know about.

    This is primarily a Papyrus x Shy!Reader story, though there are some moments with Sans. It can be interpreted as romantic or quasiplatonic based upon your perspective.

    Interspecies racism is part of this story's plot, since humans still hold quite a grudge against the monsters.
    Overall, this is a fluffy tale with some bits of angst on occasion.
