You were a normal human. You went to college, you had a life, friends, family, etc. Apparently, the void didn’t care much for happy endings, and you find yourself strapped to a table in an underground lab.

Or, you get sucked into the void and your soul is placed in the body of eight-year-old Sans.

Summary
Ink and Error have been at conflict for years, they fight continuously with no resolution leaving the balance of universes suffering as a result. As they both are forms of guardians in their own right, will they learn to work in harmony? Perhaps something else will build along with the forced partnership.
They both have their own secrets, Ink hides what else he has to protect more than just the alternate universes and Error’s truth behind his continued existence and his true thoughts on the painter.
Everyone else just has to sit by and watch them and just hope they work out their differences before the timelines shatter.

Summary
These are a series of short stories with variants of Sans from different AUs for a potential bigger fanfiction I wanna write in the future.
In these stories, Reader is Gender Neutral and is Referred to as Yin(short for Y/n for convince). I will NEVER describe the Reader or their appearance, there may be times where I have the reader wear clothing and describe it, but it will not be very often so you are free to imagine any outfit in these scenarios that fit with the setting. For certain Sans AUs, I may make you shorter or taller based off my own headcanons for how tall characters are, but that is as far as it will be. For Oneshots with sex or similar stuff, gender neutral terms and compliments will remain as well, but I will write separate sections for those that have either parts.
Terms of endearment will be gender neutral, compliments will not fully describe your appearance, etc. I WANT THESE STORIES TO BE ABLE TO BE ENJOYED BY PEOPLE OF ALL SHAPES, SIZES, ETC. IF YOU FEEL SOMETHING COULD BE BETTER, LET ME KNOW IN COMMENTS HOW YOU FEEL AND FOR CONSTRUCTIVE CRITICISM. THAT IS ALL, THANK YOU FOR READING AHEAD!

Summary
Your routine is usually the same. Wake up, eat, open up your cafe, close up your cafe, go home, eat, sleep and repeat. But what would happen if a gaggle of Monsters enters your coffee shop after their original one goes down in a blazing inferno? What would happen if they kept coming back? What may happen if you ended up befriending these Monsters and learn about what's going on behind the scenes of their chaotic lives? And what if you are not as ordinary as you first believed? Join Mc (You) and the Skelebois as you all become friends, learn what is really causing all of the chaos in their lives, and how they figure their ways back home.
Yes there will be romance Its just going to be later in the fic that being said.
Warning this is a SLOW BURN! I am Not Playing around with that slow burn tag.Give some love to Clucktherooster! They helped me a ton already and will likely continue to do so for the rest of this fic so check out their works as well!
BlightTale Belongs to Me (Sky_Playss) and NotcoTale Belongs to Clucktherooster Respectively

Summary
Tyrant Xilian's avatar had arrived in what looked to be an alternative reality from his own. This reality was what looked to be from the famous game Undertale, known for it's complexity and wide establishment of fan creations. He took the appearance of a monster called "Monster Kid", tricking others with his disguise he played along, mimicing the monster perfectly.
However, the current games route he was in was known as the genocide route. -

Summary
"Limerence is characterized by an intense and persistent obsession with another person, accompanied by fantasies, longings, and a strong emotional dependency." Someone inhaled sharply upon hearing the goddess's wise words. Respectfully, no one looked in the direction of the King of the Heavens.
"A person in limerence might not want to feel that way," the goddess of wisdom, Alphys, continued, moving on to another sentence that definitely caught Nightmare's attention. "Perhaps the target of limerence isn't even her type. But there's something about that person that attracts and triggers her," she concluded.
After a minute of silence, Negativity decided to break the tension.
"...You know, I wish I'd known about this, before all of you jumped to conclusions with Death, and got me involved in that whole immortal mess." Nightmare sighed, closing his eyes to avoid the embarrassment the entire Pantheon of gods must be feeling as they looked at them. "Honestly, you..."
"You have no right to separate me from my chosen one, my mate." Death growled, causing a blush to appear on said mate's face.

Summary
You're a Mer-siren and you live off the coast of Ireland in a lagoon on the island named Burrow Rock. You used to live with your parents, but even they couldn't help but be caught by those damn fishers.
The island was mostly abandoned, except for the occasional dolphins and seagulls. Because of self-isolation getting to you, you started talking to the fish, and everything seemed a lot more fun from then.
Burrow Rock wasn't too special, but it had its times when it never seemed to stop amazing you, which only made you long for the power to walk through it.
But alas, you were cursed with a shiny, green, glittery that bound you to the waters for obvious reasons, how are you supposed to walk with no feet? It's not like you had a wheelchair!
Everything was fine, besides the sailor men trying to kill your friends 24/7, everything was chill. Nobody was going to take anything from the island, or the island from you.
But who knew you were bound to end up in a bathtub of all things, on a cruise ship, miles away from your home, and with a skele-ton of new roommates for the next 5 days? You didn't, but golly this is gonna be fun.
