Summary
Adults lied. It was what they did.
They said they would take care of you, but they didn’t. They said they would be there, but then they died. Sans had gotten used to it.
But Papyrus shouldn't have to.
And if Sans had to take matters into his own hands in order to make sure he kept his promise to his little brother? Then so be it. It was Sans and Papyrus against the world, and some gangly skeleton with gentle sockets and a weird font wasn’t going to be the one to change that.
—
“Sans, wait—! Please, let’s just talk for a moment—!”
“no way, you creep! leave me alone!”
“Excuse me? I’m not a creep! I just wish to talk! You have many people very worried about you—”
“nah, you’re not excused. gimme 500 g and then i’ll consider it.”

Summary
Long ago, two races ruled over Earth: Humans and Monsters. Religion and fear of differences troubled the fragile peace on which both species were living so far. A war for faith and honor soon engaged between them. Long. Endless.
Sans and Papyrus, two young skeletons brothers, sons of the Royal Scientist, lost everything in the rage of the fighting: their home, their family, their childhood. During a human attack, they suddenly found themselves delivered to bullets and bombs, all alone.
Both of them started a journey in the devastated landscapes of the end of the war to join Mont Ebott, where Monsters are preparing for a last battle. But could two kids survive by themselves in the wild and without any help?

Summary
It was cold, so cold, too cold.
You were draining, slowly, as an orange whose juice would be taken....
the warm juice, the warm and red juice. Leaking, through a dam's rift.
You felt like an empty Shell, empty of what it contained, empty, too empty.
You couldn't see anymore, couldn't hear anymore, couldn't feel anymore.
You were surrounded by emptiness. An emptiness that took everything, and nothing at once. Then, Came the light.
and you were no longer… empty.

Summary
I like the head cannon of Sans having raised Papyrus. I also like the head cannon that all other skeletons died when the Barrier went up. So we all know PTA Sans, the punning and protective skeleton who join the PTA for Frisk. The thing is, in what I've seen, he acts experienced.So I like to think that he did the PTA before, for Papyrus. He had to make skeleton needs and growth and customs known to monsters who had never even seen a skeleton before. And we know how much Sans loves his brother, so he was probably very dedicated. Maybe he transferred some of that dedication to the human PTA.

Summary
Lyra, a devoted Undertale fan, decides to play god by rewriting the game's code to grant Asriel Dreemurr the happy ending he deserves. But when her actions pull her into the Underground itself, she finds herself trapped in the very world she tried to control.
!!!!This story contains graphic descriptions of violence, body horror, and themes of grief, trauma, suicide, and manipulation aaaand a lot more. While it may seem fluffy at first, darker themes emerge as the story progresses. There are still plenty of warm, comforting moments, but I don’t want to mislead anyone expecting a purely lighthearted tale!!!!
Also, this is very slowburn — Chara’s and the MC’s relationship progresses slower than you might expect. If you find yourself feeling frustrated with how I write Chara early on, please know it’s intentional and part of the slow build. Thanks for giving it a chance! <3
!!Currently editing. The story itself won’t change, just fixing details!!

Summary
It was bright. Too bright, what had just happened? Flickers of memories passed through Sans’s mind in a whirl. “Doctor Gaster!” He heard a faint scream. It was muffled under his own screaming of his mind.
“Someone get the kids out of here!” Another voice said. The bustle around him felt as if it was going in slow motion. The colors faded from his vision as he collapsed onto the floor.
“Brother! Wake up!” A small voice peeped. Sans felt his consciousness fade. The nausea he felt was too strong, and he welcomed the darkness.OR
Sans is left to care for his rambunctious younger brother Papyrus, his health suffers as a result of overworking. On top of that: memories of the past plague his dreams. Sans must work to overcome his trauma while also allowing himself to be supported by those who care for him. Tags to be updated as chapters are released.

Summary
A story of a past long forgotten.
People tend to disregard the past now that the future is fleeting and uncertain.
Yet by doing so, they remain unaware of how things came to be—the blood, sweat, tears, and lives buried underneath the city’s paved road. The efforts were made to make Last Ebott City the protected city it is in the modern day.
Then again, no one would be able to believe that the lives of thousands in the city started as a whimsical dream from a trio of brothers who built the utopia from the dead soil to the prosperous and self-providing fort that stood the test of time and danger.
Yes.
No one would believe that the childish dream of a young skeleton who saw the world of another universe sparked the fire that would burn with a desire for a hopeful future.
