bnha crossoverfanfiction undertale

This is my first fanfic so it might not meet your expectations. 

This is a bnha and undertale crossover where (y/n) is Sans' and Papyrus' younger sibling. (y/n) is enjoying a nice picnic in waterfall with everyone until they get sucked into the bnha universe. 

BTW (y/n) is going to be classed as gender neural. Of course (y/n) can look however you want like every reader insert and with opportunities to choose, so feel free to describe (y/n) through your eyes it would be interesting to see how many differences there are.

apart from (y/n) and this story/plot nothing belongs to me. obviously bnha characters and undertale characters belong to their creators but unless I say so the art is not mine and most of it was found on google so I'm sorry that I can't give credit where it's due.All Rights Reserved

Storyshifted - (SS!Chara X Reader) by 1m0nlyhumn

Hunted down, the only way to escape was up Mount Ebott. Y/N and Frisk, two extremely close friends, needed to continue running, they didn't want to go back. Not back there. The hunters were too close by now, but the two found themselves ready to jump down a large hole. They'd rather die than have to go back. So with one step back... they found themselves falling to their death. But... they didn't die. (Chara: 16F | Y/N: 17M | Frisk: 15F [Changed my mind Metta no longer exists in this universe 💀]) Story started on September 8th, 2024. (This story is inspired by A Shift of Events, made by Incurvat)

The Angel and the "Demon" (Female Chara x Angel! Male Reader) by all_about_undertale

Everyone carries around their dark secrets if it's just one, or many. It doesn't matter, they can't tell anyone. At least they think so. As for (Y/N), well... he carries a secret no human could imagine. Because he is not really a human. But his will of staying away from the others will soon be tested by a certain someone. ???: An angel? Please, I'm serious! (Y/N) Well, archangel to be exact, more or less... Artwork used for the cover by: yukarintizu (Go check them out, they're an amazing artist!) This story will contain (a little) explicit language, violence, and fantasy violence, and in later chapters sexual content.

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

Red Eyes [Chara X Reader] by CouldYouJust

This story is inspired by many other works and may bear some resemblance in certain places. However, I will endeavor to make this story it's own. 2 years ago monsters were released from the underground, ending their centuries-long imprisonment at the hands of ancient humans. Not a soul remains in the underground. But that doesn't mean no one's there. Be it chance or fate, The First Fallen will soon meet an all too curious human as he ventures into the deep beneath. The Reader or [Y/n] is male and Chara is female. I apologize if this bothers you it's just how I've always seen the character. Disclaimer: I don't own these Chara-cters nor do I own Undertale. This is just for fun. This story's rating is [M] for explicit language, violence, suggestive or sexual themes, and fantasy/fictional violence. My lovely reader @NightTheDemon1 told me that the artist of the cover is a Twitter user known as @A___IRAA. Thank you!

Home (bad sanses x child reader) by catsinboxes17

You were an average kid, somewhat having a older mind than most of your classmates. you had always been into the undertale fandom, and even knew almost everything about the aus and soul colors. while what seemed like a normal day at school quickly turned around after a huge bang struck the class room next door. in this story y/n is nonbinary and 12-16 years old. But more interpreted as 14 I post a new chapter every 3 day and 5 days at the maximum. WARNING: this story will mention some forms of slight emotional harm. And Sexual abuse. Readers be safe. Please if you are in any danger, contact someone. You are not alone. With that aside enjoy the story . This story is finished as of September 1 2022, I encourage you to read my other story "Our Disturbing Love" And in the next month or couple weeks I plan on creating another bad sanses x reader.

Cursed (Female!Chara x Male!Reader) by Incurvat

[THIS IS THE DEFINITIVE AND IMPROVED VERSION. THE OTHER 'CURSED.' IS DROPPED. I HIGHLY SUGGEST READING THIS AND NOT THE OTHER ONE.] 7 years ago, monsterkind was freed by two heroines. Following their freedom, magic became common for humans. Y/N, a young man who's magic is mighty special, hates it for special reasons. But a certain someone might change his views. Story started on 11/07/2024. Story finished on 23/03/2025. Cover by Nick Nitro. (Yes, Storyshift Chara. But damn, can you blame me ?) Lastly, inspired by Red Eyes from CouldYouJust.

He's Mine (COMPLETED)(Yandere Papyrus) by BubblyShip

(UnderTale rightfully belongs to the amazing Toby Fox, I am not creative enough to make that masterpiece. There is a person named symphysins who drew some work of Yandere UT! Papyrus for Sans, and I really liked the idea of a creepy UT! Papyrus and decided to write a short story on it. Also, Frisk can't reset, she never had that ability. The cover is my own art.) "Why is everyone I date dying?" Sans asked, covering his eye sockets. "Am I cursed or something?" "I'm sure you're not cursed, Brother!" Papyrus said, patting his back. "T-There might b-be a Yandere on t-the l-lose!" Alphys piped up. "A Yandere?" Sans asked, tilting his head. "What's a Yandere?" ~~~~~~ Sans felt like something was wrong. Everyone he tried to date ended up dusted, and he couldn't figure out why. So, when Alphys explains to him what a Yandere is, he realizes he might be someone's Senpai. Determined to stop this endless cycle, he teams up with his friends to try and find this psychopath. If only they knew he was closer than expected.

Undertale/Deltarune x Reader [Not discontinued.] by BlackTheDetective

The title says enough,but basically YOU are a child that fell after Frisk. You have lost your parents in an ''accident'' And in this story,the reader is MALE And this is my first time writing something so,i might not even finish it. But if i can get enough DETERMINATION i might do a version where the reader is a girl Also both Frisk and Chara(if i make her appear) will be a girl in this story idk why,it makes sense to me. (Truth to be told, idk if i'll ever be able to finish this story, so don't expect much.)

His Unfazed Determination~ XTale Frisk x reader by Spooky_scary_Sam

[art used for cover by Rua Shio! All rights to characters to their creators! Gender neutral!] "You underestimated me, I'm determined too!" "You don't understand, I don't want you to die out there and for it to be HIS fault!" ----- Y/n had been abandoned in the universe they lived in, no one cared for them. One day, a skeleton like the Sans you knew, though dressed differently and possessing a more kind demeanor brought a tall skeleton and two humans to the universe you lived in. Those humans and monsters had changed your life forever. But you would soon figure out you weren't fully human, and the universe you lived in was anything but perfect...
