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

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!)

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.

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.

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.)

|Broken| a Napstablook X Reader by CloverStream

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)

Adoration | Sans x reader by Fml_2171

Sans and Y/N meet on the surface after the monsters are freed. But sans dosnt seem fond of them at first. What will happen? ⚠️TW: There may be some NSFW content, in harmful launage, and sensitive content in this fanfic. If you are under 14, I would not recommend it, but I can't stop you, so be prepared.⚠️ NONE OF THE ART IS MINE ENDLESS I SAY OTHERWISE.

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😆
