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

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...

"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.

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} .

A SANSational Love | Completed | by scooby22foxee

Btw this is my first fan fiction so please don't judge if I make any spelling mistakes or anything. Thanks! Frisk has broken the barrier but humans refuse to allow monsters to come up to the surface. Chara now has her body back, using both hers and Frisk's determination. She has been reunited with her adoptive parents, with Flowey her brother, since Asriel can't stabilise his body to live without a soul, and Frisk who is now her sister. Frisk has also met Blueberry (Underswap Sans) and Edge (Underfell Sans). They live with thier brothers in houses in Snowdin. All three Sans' love Frisk and she loves all three back. Who will she pick? Btw the universes kinda collided but only the skele-bros got stuck in the Undertale universes. (Just use ya imagination) It involves, #friskxsans , #blueberryxchara and edge/fell x one of my oc's (April) All CHARActers belong to Toby Fox😆

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.

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.

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.
