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

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.

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)

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.)

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!

Broken Souls 1 - Sans × Monster!Reader COMPLETE by NeonVixen

Instead of you being a human, you're a monster in the Underground. I will continue to go back and edit or merge parts until I have completed the story. Parts that I am actively working on will be labeled "[under editing]" Also, art cover is an action figure off of fangamer.com. they have more action figure characters that are so cute. I am not affiliated in any way with fangamer.com. This is my 1st story in a VERY long time. I like to do things a little different as far as reader inserts go. 1. Instead of Y/N for your name, I use _______. Why? Because when I'm reading a story and read Y/N I think Y/N and then have to remember the name of the character I've made in my head, where as if I see _____, I immediately replace it with the name because there is no word for me to read. Love it or hate it, comment. I can be persuaded if the masses disagree. 2. I don't do H/C, E/C, etc., because it does the same thing that Y/N does for me. Instead, I will be as vague as I can on insert character descriptions giving the reader more freedom to imagine what they look like without forcing it down their throats. 3. For undertale specifically, I am more inclined to make monster!reader inserts, because that makes more sense to me. This will not always be the case. If the masses prefers human!reader inserts, comment so that I may be persuaded to do so. Also, feel free to ask for requests. The more requests I get, the more inclined I will be to do more stories. They don't just have to be undertale related. I will give you credit for any requests at the beginning of the story.

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!)

The Boney Hero (Sans x BNHA crossover) by DontAskImN0body

At a genocide run Sans unexpectedly wins against ¿Chara? and something strange occurred, the timeline was thrown into chaos. As a result of this chaos, Sans unknowingly was brought to the world of My Hero Academia where lies a world full of quirks. Now we will find out what journey is to unfold with Sans now in this world. Welp this is my first story... so yea..... im pretty sure I'll make a ton crap of mistakes basically typos everywhere.. sooooo just bare with me okay? I'm also always running on boredom and laziness while writing this. Also this is fucking cringe... Welp um..feel free to drop your ideas I'll definitely consider them... ¯\_(ツ)_/¯ Also this story is definitely not original and inspired by a lot of different other stories that came before it {!Completed} .

"Heya, Feathers." MafiaSans x Monster Fem!Reader by SoapyFlames

#6-mafiatale (WOO!) 12-21-22 ⚠️ WARNING ⚠️ this will have shooting, swearing, gore, attempted sexual advances, and other triggering content. If you aren't comfy with it don't read! (EDIT) If there is a demand, I can make a separate story with male pronouns! I'm currently also re-reading the story to edit any autocorrect mistakes, so if there are some parts that feel like should not be there then I will be getting around to those. 👍 A long time after monsters were freed, they went into different professions, though racial discrimination against them caused monsters to fall into crime, luckily, y/n (who is currently 26) was able to find solace in work as a circus performer, having to perform seemingly life threatening tricks and stunts which brought in some cash. Though once she's hunt down by a gang for her wings, will her agility save her? Y/n is a bird monster, human in most ways but having large wings, talons for feet, clawed hands and feathers sprouting over her body in small patches. Mom: [Mom name, Last name] A human woman with h/c hair, s/c skin and dark black eyes who works as an engineer, loves you to bits! Dad: [Dad name, Last name] A humanoid bird, complete with wings, talons, claws, a beak, and completely feathered. E/c eyes like your own. He works as heavy duty, lifting objects to higher places. Loves you a lot but is gone pretty often. Brother: [Carter, Last name] Left around 14 to go work with gangs, became a professional hitman and caused you and your parents to go into hiding at some points because of rival gangs. You honestly hate him. Credits: Mafiatale is NOT owned by me, but the story is. Art (unless stated otherwise) is also NOT made by me.

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...
