Summary
"Chara Dreemurr. Though I have to assume you already knew that."
“Clover,” He shyly made an attempt to register how their hands felt–cold as a corpse and smooth as silk. His were too warm, too rough. Could tell, though, during that moment his mind struggled to record forever, a rare grimace on their features, a half-contracted smile–which made his eyes narrow and an amused deduction suddenly hit him. “Though I think you already knew that.”
Didn't even have time to say his last name before Chara fatefully released him, not before giving a light squeeze, as if trying to tell him something that was impossible to decipher. “Who knows.”
———————
Clover thinks he's gotten used to life around city folk, but what about that stranger with their eye on him at every turn? -

Summary
"They’re sitting in a bed of golden flowers somewhere far beneath the earth, and, as far as they can tell, for better or for worse, they’re decidedly still alive."
_ _ _ _ _
Frisk climbs a mountain and inadvertently awakens an ancient terror sleeping beneath the flowerbed they land on when they fall. If by "ancient terror" one assumes the less-popular definition of "annoying narrator-ghost princet of monsterkind who is now, unfortunately, permanently stuck in their head."
Chara doesn't want to be awake. They especially don't want to be helpless in the back of a bloodthirsty human's head, watching them ruin the only home they've ever known with no power other than their voice to fight back with. Luckily for them, that's not what's happening at all. Unluckily for them, they may have to re-evaluate a few things about their worldview. Which, for someone as set in their ways as them, is not an easy thing to do.
(Then there's the matter of the weird flower, Frisk's unusual powers, and the Longest of Long Days the underground has ever seen.)Chara & Frisk no player AU true pacifist. Updates semiregularly from ~80 chapter backlog!

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.
La traducciones del "los pájaros y abejas" hasta el "No sirve pa' nada" no son mías. Del resto de traducciones si son de mi autoría

Summary
“Learn from me, if not by my precepts, at least by my example, how dangerous is the acquirement of knowledge and how much happier that man is who believes his native town to be the world, than he who aspires to become greater than his nature will allow.”
- Victor Frankenstein, "Frankenstein; or, The Modern Prometheus" by Mary Wollstonecraft ShelleyTold through an organized collection of his diary entries, speech-to-text transcriptions, and other methods of recollection, "This Next Experiment" thoroughly explores the life and times of Dr. W.D. Gaster, the Underground’s once-beloved Royal Scientist.
Will you be the carrier of memories long-forgotten by all but one?

Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
You are a massive fan of theory crafting videos. While you weren’t as preoccupied with them when Undertale came out, you’ve matured enough to find the beauty in them once Deltarune started coming out. Following the release of Chapters 3 & 4, you decided to get your hands dirty and examine the game for yourself in hopes of finding your own meaning. However, as you start up the game, something very, very interesting happens. What follows can be described only as a once-in-a-lifetime opportunity that melds the boundaries between fiction and reality.
