I don't really know, just an attempt. Might go well, might not. We'll see.

Ah look, another Undertale x BNHA crossover. In this story, sans always loses to Chara in his never ending battle against her. Then, one day, mysteriously, someone "accidentally" corrupted Chara's SAVE file. Instead of sans being sent to his normal home, he is instead sent to a brand new world, one where heroes and villains exist, and everyone has powers just like him. How will sans cope with the ever setting dread of being stuck here? Is there a way out..? Also, I'm not adding AU sans to this story. Simply put, Ive seen way to many fan stories suddenly shoehorn in AU sans. But if requested I may make an AU with that AU sans instead of classic sans.

In this au classic sans au gets invaded by an unknown entity which freezes everything. Sans is the only survivor in his au. The aus have to find a way out of this au alive with classic sans in tow. Will they make it out alive?

(On hold, only Toby knows how long) A normal day...... that's what I thought..... I never new that I would have an experience like this..... *Hi guys! so this is an Undertale fanfiction. Undertale belongs to Toby Fox and the other AUs belongs to their respective owner. I do not own anything else in this story except for the story plot line and the pictures that I may add unless stated that it's not mine. cover by me and I hope you guys like it. this book may have different/various endings and I'm planning to do a slowburn so just a heads up on that.*

(Cover was drawn by me!) The rain had felt so surreal to Classic as he laid among the field. Thick grey clouds rolled past as thunder rumbled in the horizon. Trees swayed as the breeze kicked up the loose leaves and carried them away. Everything felt so unreal as he looked to the surface world. He had finally made it, or so he had thought. One moment there was a peace of mind. The next they were captured by unknown origins. Sent to a facility, they only had each other. At least until they meet some of the other inhabitants. Monsters like themselves. With growing friendships, will both sides be capable in achieving future goals. One group wants to return home. The other wishes for freedom. Maybe their arrival to the new world was not a mistake. Just maybe they were capable of aiding their new found friends.

Yeah I'm doing this now. If you want more info go to the first chapter there will be some rules like how to request. Okay? Okay. Let's go! Also take whatever you think is cannon and leave it here because this book ain't about any of that. (Non of the art is mine unless stated otherwise.)

*Cover picture is not mine* ¡Warning might contain Muture things at some points¡ Frisk was accusing Sans of hurting her putting fake scars on her. Everyone was believing her even paps and some of the sanses thought he was doing it too.The people who believe him where Geno and reaper which where any amazing couple. After an argument Sans got kicked out of his house heading to the forest to relax and rant

(on going!) -so, classic was fighting chara or frisk, frisk/chara won, and something appears on in front of classic.. teleport? he just presses it and he teleports in a forest, which his injured has gone. he is black and white, i meant the color, his color changes back to normal. he found his family again, papyrus, toriel, frisk, and others (i forgot their names lol), he just forgotten the past the wau they killed. it was becoming normal but got ruin. classic got teleport into a timeline (i forgot). in the story continued.

Classic Sans incidentally finds himself working as a maid for eleven different skeletons in a mansion, after accidentally breaking a statue worth millions of dollars. What he doesn't yet realize is that all these skeletons begin to quickly crush on him, and some of them don't like to share. || Reverse-harem where eleven AU Sanses are crushing on Classic! || ***Artwork is not by me!!
