Summary
THE GREAT PAPYRUS PROBABLY DOESN'T NEED FOOD!
...probably being the keyword there.
But it's an experiment! A very scientific, very important experiment! And it has absolutely nothing to do with how disgusted food makes him feel!
Sans can't know about it. It's not that he doesn't trust him, no. It's just that Papyrus knows Sans wouldn't like the idea of his brother trying not to eat for a whole month.
or
Eating never came easy for Papyrus. The taste, the texture, the strange disgust that followed... none of it made sense. But when he hears skeletons might not need food at all, something inside him clicks.

Summary
Frisk could feel Chara narrowing their eyes at them. "Seriously, can you please take that stupid bandanna off your head?" Chara sneered. "It makes you look ridicul-"
"Mandanna," Frisk interrupted.
“…excuse me?”
"Mandanna. Not bandana."
”Are we seriously gendering the bandanna just because it has abs on it?”
"Yup!"
”…I really wish that others were able to hear your sass.”
"I don’t know, I kinda like the idea that you’re the only one getting to see this side of me." Frisk looked in the window of a house they were passing by, winking at their reflection in it. "Makes you special, doesn’t it?"
”I- Stop flirting with me. I’m a dead person’s voice in your head!”
"No."

Summary
An original AU where every monster receives a special gemstone at the age of ten, a condensed crystallization of their own magic called Crysalith.
In this universe, monster magic is far more potent than in most other AUs. The Underground overflows with excess magic, forming various types of magical gemstones (often referred as Mana Stones). This abundance of power is one reason their AU remains one of the few where the ancient Sages, now calling themselves the Wizarding World, have survived, while others have faded into extinction.
Though Crysalith are not directly tied to a monster’s SOUL, they are bound to their magic. These gemstones act as magical catalysts, providing extra support. They aren't strictly necessary, but they're incredibly useful, serving as a kind of pressure valve to siphon off surplus magic so the monster doesn't overload.
This practice is a deeply rooted part of monster culture, existing long before the Great War.

Summary
In a freak accident, Gaster has unintentionally created a human soul.
Fearing his creations demise and being used as one of the seven souls to break the barrier Gaster hides it away in his lab.
Little does he know that by creating this small soul he has taken on a role that he did not expect from a accidental experiment.He becomes a protector, a creator, a defender, and most importantly...
He becomes a father to the soul.At least he has some experience on that last one.
Caring for two young skeleton children is hard, a human should be easy.Right?
