Papyrus Stories

What would happen if the Destroyer is a fusion of human and monster SOUL? Wanna find out?

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)

If given the chance, would you start over? After falling into a timeline where nobody was murdered, his mother never died, and his father was never erased, Sans should be ecstatic that he has a second chance with his loved ones. But there is no denying the trauma he'd been through, either. Everyone is supposed to be dead, after all. What if Frisk comes back to take it all away again?

Saitama gets stuck in the Underground. Well, this'll be interesting!

• I reccomend you do not read this, this is my worst work yet despite it being my first. There is another story on my profile that is under development and editing. Other than that everything else here has remained untouched for over two years. DISCLAIMER: i do not own undertale nor any videos, pictures, intro, etc. And i reccomend checking out the original creators You are an ordinary teen or are you with a weird crystal appearing right next to your bed with it telling you strange things and having an encounter with a flower saying you soul is special are you really normal and is the senior year of high school really be normal with monsters starting to teach and attend school will your life really be normal? ------------------------------------------------------------------------- (This is the completely Un-Edited Version Except For The Disclaimer And Part/Chapter Date, For Those Who Would Like The Original Reading Experience) (Disclaimer) This is by @Shyboxes. I am archiving this with permission so people will still be able to read it. :)

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.'

Sans and Papyrus were just trying to have dinner. They didn't expect things to blow up (literally). Now they have a destroyed machine and a young babybone that they suspect as a Shifter. Where did they come from? And who's life privilege they need to remove? Because this babybone is clearly been abused or worse. Now then, where's that parenting books Sans been storing since Papyrus a babybones, he's definitely need a review if they want to keep the kid from getting killed. At least the kid's adorable...

Short Summary: An Undertale AU, which is a crossover with my The Last Star Seeker series. Long Summary: A young human girl falls into the underground. After being caught and taken up to the castle, they face their judgment. Little did everyone know that this girl had magic like all monsters. The king decides to SPARE her in hopes that she could break the barrier without having to take more souls. Years pass, and Astrella hasn't figured out how to break the barrier, but when she sleeps, she's given messages that shake her to the bone. So, with the help of a funny skeleton, they solve the mystery together and maybe more about themselves too. Yes, this is an oc x canon story 👀

In this AU, Undertale monsters live amongst humans in the One Punch Man verse. How will it all play out? (THIS IS DIFFERENT THAN PUNCHTALE!!!) As an AU, characters may differ from their canon counterparts.

The story officially begins when Toriel dies in her universe mysteriously. Gaster with his allies show up and take her soul remains back to his lab to save her life. Toriel then had DETERMINATION injected into her. Most of the DETERMINATION was collected from humans in multiple different universes. Gaster created the perfect solution to end RESETs and genocide routes that plague The Multiverse. A new kind of boss monster with the ability to utilize the power of the savestar. Toriel, who got reborn as Gaster's daughter in his lab due to a serious situation that happened, it was the only way to save her life. Gaster embarks on his quest to bring peace to The Multiverse. However The Savestar becomes corrupt, doing more than its intended function. If the RESET function is over-worked, it will erase a universe. The more universes that are gone, the more The Multiverse dies. They explore every universe they're able to, attempting to fix the savestar and rid the ability to RESET, helping others and themselves. ---- Note: This AU has themes such as Suicide, frequent swearing, mentions of needles and more medical equipment. Be careful upon reading incase you are sensitive to these topics! Also moments in the story of characters smoking and mentions of Alcohol. Note: All 7 of the finished Chapters are published. Chapter 8 will start in 2026. The AU is still in progress. Enjoy. UnderVanquish has two creators: SoulerClash and C!rquette. Co-Writers: Capt.Gunscar, Eversius, JK, Darkswaver, Hollow and Marble. UnderVanquish-Comic Creators: SoulerClash,Hollow and Marble. UnderVanquish-Game Creator: SoulerClash. Update: March 2026/Comic is not going to happen for a while but there is an UnderVanquish game in progress and it will be massive, same amount of chapters as the fanfic and each chapter will be a game. Chapter 0 which is prologue is getting new lore. Chapter 8 is going to be delayed. I will enter new content sometime this year once I have enough content done.

Disclaimer: Characters from Undertale belong to Toby Fox, I only own the Oc's An Au where things seem normal. Frisk falls into the underground, starts the genocide route, Chara controls her, they kill all the monsters. But who would think that the secrets would come from our own smiley trashbag. 2nd Disclaimer: The plot of the first and second season will be deprived from Glitchtale (created by Camilla Cuevas), so I advise go checking it out on YouTube.

You, as the reader, are in a neutral state of being. Instead of picking sides, you the Reader would rather look at each side and work around siding with anyone. Being neither good nor bad, guardian nor destroyer we choose to be the anti-hero. For the record, none of the images in my book belong to me. All art credit goes to the original creaters.

after the barrier was destroyed all the monsters in the underground were free and happy but for the humans well they weren't happy at all not even in the slightest because as it turns out the only reason why they created the barrier was to not because they hated the monsters but to keep four Pacific creatures trapped inside that's a danger to everything and everyone and now there free

I found some books on Undertale reacting to be completely abandoned and decided to do it myself.

"Don't judge a book by its cover, doll." Medusa wasn't really the most liked monster in Snowdin, though she didn't particularly care. When Frisk begins yet another run, they are introduced for the first time. While being stereotyped, she goes to one flame haired man to talk to.
