Summary
Life is comfortable out in the wilderness near Nowheresville, New Hometown. You don't get bothered by the obnoxiously loud noises of the construction sites, and you get to keep the company of various animals... Cows, it's mostly cows. But if Clover had to choose a downside to their lifestyle, it would be the constant, looming threat of vampires descending upon the innocent townspeople.
This fanfic is not affiliated with prettyinpink2468's Cocoa powder Vampire AU on tumblr, but it is SLIGHTLY inspired by it.
This fanfic is also not being actively proofread or beta'd because i can't read and none of my friends can either. We ride with what we write over here💥

Summary
The world changed when the barrier broke. With the monsters and the child ambassador came an influx of new diseases that are barely understood. You're a young scientist and have been called upon to work with monster-kind to help treat these strange new conditions, but you begin to notice that you have changed alongside the world - more so than you could possibly imagine.
High jinks and low jinks ensue as you meet a particularly punny skeleton and his friends ;)
WARNING: contents include spicy bone-zoning, VERY slow burn, painful hanahaki experiences for the mc & more

Summary
Twin Runes es un AU cómico en su mayoritariamente alegre centrado en los universos Deltarune y Undertale. Una fuerza desconocida ha provocado que aparezca un punto de conexión entre los dos universos, lo que hace que Frisk y la molestia fantasmal Chara tropiecen en la vida de Kris en uno de sus muchos reinicios (para gran disgusto de Kris). Se produce un caos que rompe el juego.

Summary
Onto glitchy, uneven ground they fell, looking up at the sky that wouldn’t last. The sky looked abnormally bright, with the earth itself sputtering beneath their limp body. They reached forward, grumbling before rising up with a stumble, wobbling over to the cliff as they dust themself off. They stared down at the bottom of it, frowning. It was so high up, yet they.. didn’t want to really take a step back.
The sound of a soft crack entered their ears, yet they continued to blankly stare down, before their gaze met the town just beside MT. Ebott. Another crack, yet they just relished in the view. One final crack, and they begin to stumble downwards. They pay it no mind considering their earlier fall.
What they do pay mind to however, was a large piece of the cliff cracking, falling off and bringing them down with it.
OR
How a glitchy, traumatised Frisk (and Chara) met Error and Nightmare, and how that caused them to meet the Bad Sanses.

Summary
There’s a limit to the things you can do today. Accepting this is healthy. Thankfully, there’s always tomorrow.
It has been five months since the barrier broke, and Monsterkind was freed. Frisk is trying to make sure no one gets left behind. Some Monsters willingly stay behind, and others struggle to make the move. After some failures and successes, Frisk will begin to realize that getting to the surface is not enough. To save Monsters, no, to truly save everyone, it takes more than just a little sunlight to solve problems.
It takes risks. It takes knowledge. It takes patience. It takes friendship. And, sometimes, it takes someone else to help.
A post-pacifist ensemble story that focuses on Frisk still trying to SAVE everyone- monster and human alike.

Summary
Falling again.
The air rushes past you, tangling your hair in the same way it always has. Your heart pounds at the same tempo it always does. Fear races through your body and you count the seconds–One, two, three–before your body becomes overwhelmed and dizziness takes the feeling from your fingertips.
It never gets easier, does it?
--
Frisk frees themself. Somewhere along the way, the presence of their Soul within their chest becomes comforting.

Summary
A field filled with dust and dried blood. A field where the last words and cries for help were drowned by the hits of sword blades.
The war between monsters and humans is underway. Started with fear and a feeling of insecurity, and it could end in any way. Both sides having only one goal: to save their home, from people they once called their friends.
Two sides, one winner and no matter the cost.

They may fight to stop the cycle, but some will not come out the same as they once were.

Summary
“At the risk of sounding overly sappy,” Chara started, drumming the edges of the book as they sat it down on their lap. The cover of ‘The Modern Textbook of Toxicology in Monsters and Humans’ glinted in the warm yellow light of the room. “I feel...wel- Angel Above and Below, Flowey’s doing the face again.”
Chara reflects on the people that surrounds them one night during the summer vacation trip to Hometown.

Summary
The Barrier's broken and the monsters are stepping out into a Surface they've dreamed of for years uncountable and forgotten. The human that helped them break through is at their side, just as unfamiliar and unsure about the Surface as they are. Upon first glance, the monsters stumble upon another human as they emerge from their prison. A human like any other, but to the monsters 'any other' human has been instrumental to regaining their footing on the Surface. Will this one be too? And are blushed cheeks something every human wears on the Surface? Come along on a journey with humans trying to understand magic, and the memories that follow. Following not as candles that warm, but as shadows that haunt. The human condition changes ever so much when exposed to magic, but how much? And how much can one human take before becoming determined?
A smorgasbord of events from tidying up a goat family to magic of the soul!

Summary
I don't have any vague summary.
But essentially, it's Deltarune with Undertale Red and Yellow sprinkled in.
Kris' SOUL is comprised of three souls, Frisk as the Red SOUL, Chara as the Black SOUL, and finally Clover as the Yellow SOUL.
This AU will also feature UT Yellow characters, integrated into Deltarune. Will they have significance? We'll just have to wait and see...

Summary
After countless resets and endless repetition.. something has changed. The timeline has began shifting, changing its path for the first time in a long time. A new path Flowey hasn't seen before.
Well, it might take Clover longer to reach Asgore but Flowey has all the time in the world after all. And seeing something new finally happen has piqued his curiosity. Drawn in by the unfamiliar, Flowey watches with morbid fascination as Clover is not able to give up his soul this time. Encounters shift, monsters react differently, and the world itself begins to remember things it was never meant to.
Events shuffle. Characters act out of turn. Rooms appear where there were none. And for the first time in countless resets, Flowey doesn't know what comes next. Clover's fate is uncertain. Though Flowey knows he will get those human souls, no matter what.
