Chara Stories

Seven years ago, monsters were finally free. Seven years ago, a human was forced into bondage. Seven years ago, this world ceased to be the tale we all knew and loved. Now, the butterfly flaps its wings. How would this world react to a presence never meant to be in the script? How would it react...to You. After all, you were Not Meant To Be. Author's Note: Welcome to my very first story! Not Meant To Be is an Undertale Reader-Insert/Chara fic, with emphasis on a plot, written purely for fun. It is heavily inspired by other works in the fandom. Rated Teen (T) just to be safe. Might bump to Mature due to (little) explicit language, violence and fantasy violence, and suggestive/sexual themes. I do not own Undertale or its characters. Enjoy!

(Y/N) (L/N) was just like any other normal girl(or human to be exact), with the exception that she wasn't really supposed to fall down Mt. Ebott. . . All she could remember were memories of things that were long since forgotten and some quite possibly deleted. She too was supposed to be deleted alongside those memories, though because of some unknown reason, she never was and instead, was sent to a place where nobody even knew existed. . . What happens when a certain Artistic and Forgetful Skeleton stumbles upon an old doodle of code of a person that "never" existed?, and after some thorough thinking and decision making, decides to create that person?. . . The moment his pinpricks set eyes on the person he had just "revived". . . Something tells him that things were gonna get very interesting. . . (Note: Cover Image ain't mine, though I totally didn't go to Google-Chan and typed AU Sanses for the picture hehe... oof-)

Abandoned on Mt. Ebott at the tender age of five, young Harry's unsurprisingly died, but Death's always had a weird relationship with his variant... Meanwhile, before Flowey's revival as souless talking flower, Sans makes a discovery under the mound of snow, Papyrus has always wanted to be a big brother anyways. *Edited Summary (29/09/2025)

Join Frisk, Chara, Asriel, and their younger sister, Aria, as they share many happy moments together! 11 months after Frisk's most recent True Pacifist Run, they, Chara, and of course Goatbro himself (AKA Asriel Dreemurr) receive a wonderful surprise in their new sister, Aria. Eight years have passed since then, and the four children are having all sorts of fun with each other! Comment if you like the story, or if you have an idea of what you'd like to see the Dreemurr family get into! Disclaimer: I do not own the game "Undertale," or the characters that appear in the game. Aria is my OC, and is not an actual game character. Note: Updates may be irregular, due to the fact that I have no set schedule. Also, I may edit chapters that have already been published, so you aren't alarmed when a chapter changes.

This story takes place after the events of the pacifist ending of Undertale, where all the monsters have already left the underground. However, that won't stop problems from starting again; Frisk and his friends will have to face a new threat. DISCLAIMER: This story is based on the fact that the first human fell underground in 2015 and the last in 2060. Here, Deltarune is a sequel to Undertale; therefore, Posttale is not a copy of TobyFox's creation, but an adaptation, or what is also called an "AU." Because of this, there will be things that are different from canon and adapted to my personal preference, with no intention of disrespecting anyone; for example, the gender of the humans: Kris: M Chara: F Frisk: M Don't like it? You can leave. Understood? Great.

There be a lotta genocides. Chara lowkey gets tired of it and steals Frisk's body. Shenanigans ensue.

Clover had accepted his fate. Giving up his Soul to free Monsterkind was his final, ultimate act of justice. As his vision blurred, he surrendered to the euphoria, certain his story had ended. Then his eyes opened. He was back where it all began. Disoriented but alive-only one thought came to mind. Finding his friends. - Flowey had planned to let Clover rest-honest! But as his vine hovered over the Save button, ready to overwrite Clover's file-a flash of memory made him pause. It was the run where he lost. That alone was rare. But it wasn't the loss that made him pause. No, It was who he saw in it. Something shifted in his mind and as the gears turned a new plan started to form. - Chara hadn't expected to wake up, not after their plan to free Monsterkind had failed. They especially hadn't expected to wake up to a Cowboy slaughtering monsters. They reached for their save, determined to stop him. - The timeline has become unstable from the three beings forcefully seizing control over it in rapid succession. The instability grew to be severe enough that the boundaries between past and future have started to blur into an unrecognizable present. (Chara art by KyoBlack-H2vu)

Hi! So uh, this is my first ever book on a website so sorry if it's cringey af or not at all in character. Btw, this au is not complete 100% but it's getting there! Enjoy! (Or don't idc)

Lance lived his normal life, battling monsters, annoying clay, life was perfect. But he made a mistake that changed his life. Now he's in another dimension, has a crazy do-it-over power, and has to battle one of his friends. THIS IS AN UNDERTALE CROSSOVER (or killer tale crossover), since someone had to do it. This my first book/au so hope you all like it!

One day, Y/N was playing Undertale. Y/N finished the game, both genocide and pacifist. After the second pacifist ending, you wondered how life would be like IF the monsters actually were real. If the monsters would actually roam around and act as humans. That thought soon changed. ( Book Cover Picture is NOT Mine. I found it on google. Credits to the owner. )

A normal True Pacifist run. That's all it was supposed to be, right? Just a few more lines of dialogue 'till the run ends and the credits roll... Ah, here's where the crazy stuff happens. They fell and hit the ground... And they were NOT where they were supposed to be. The sky wasn't supposed to be red.

Crystallize [kris-tl-ahyz] refers to the process where a liquid or gas transforms into a rigid, structured crystal lattice. Or... I look at my other two Avallon and thought 'Yeah I could do more angst with these bois.'

What if Asriel Dreemurr has Frisk's determination, and Chara Dreemurr has Frisk's Body

Undertale story comic, you better watch!

Here is the different book of covers with different songs recorded by the Classroom Musical Gang.
