Sans and Papyrus enlist in U.A. This is a slightly modified version of the Handplates backstory, to explain, well, Papyrus and Sans's backstory. Sans and Papyrus remember gaster and what he did to them. The only person who knew what they know was Asgore (because they told him). I got the idea from someone called QuartYogurt they are quite good and are taking a break. Hope you enjoy! I dont like the book itself... it rubs me in all the wrong ways. So I'm ending it. Who knows... maybe one day I'll pick it up again.

[this story is under rewrite, so bare with me until I finish it please.] Sans has always followed his script, with no flaws in dialogue nor actions every reset. All because he knew it would all be pointless in the end... or was it? Fighting and dying by the kid's hands once again, Sans gives up all hope and collapses to his death. Little does he know that his story hasn't ended yet, and was only just the beginning of his tale. Will the people he meets next be able to help Sans? Or will he drown in his despair? Read to find out! Cw: Depictions of violence, gore, self-harm, abuse, and other triggering content. if you find any of these warnings as disturbing or makes you uncomfortable, please do not read this.

Haha so I was reading a comment of a sans meets MHA and they said they wanted to see a skeleton sans meet MHA so being the dumbass I am, Iam TRYING to do this! It is kinda the same as all of the others but at the same time not...? Please correct on every single thing EXCEPT my AU. Yes yes it isn't OG Sans as I can not do his canon personality better than some. Summary- The obscured wound on the skeletal figure deepened out from beyond their body. A substance that looked similar to blood started making its way onto his dirty white shirt and bright blue jacket. His sockets widened if possible as the human child before him smiled. "You are a stupid fuck Sans." The child spat with venom blood splattered on their yellow-ish tinted skin. Their eyes red, glowing, and evil, gleamed against the dark area they were in. " I told you not to fight! AND WHAT DO YOU DO?! FIGHT ME!" The human yelled as skeleton's fragile body started the melting process of dusting meaning he was almost gone. " H-hah..." The skeleton coughed up more of the blood like substance seemingly laughing at the villain before him. " I-I was a-always an as-asshole huh k-kid?" The skeleton grinned his sockets lazily dropping down to a half-lidded look. The child grunted in annoyance. "You know what? I think I'll do this route ONE MORE TIME!" They screamed happily knowing this would upset the skeleton. The human's joy was increased as the skeleton fell to the ground yelling for the mercy they so deserved. As a final grin grew on the human's face the RESET button was pressed. Sans, the skeleton, fell...That didn't happen before....Was this something new that Sans had been craving...? Maybe... Sans relaxed not even feeling the ground collide with his body.... (like my writing? Consider actually reading this shit! Also cover Art isn't mineee)

This is a mha / bnha x Undertale fanfiction story. I have made my own OC that resembles me a little bit. There will be more details about him in the story. This is my first "published" story, and I totally allow criticism. There is no shipping here, except maybe Deku and Uraraka (I don't know how to spell these people's name XD). I will try and update as fast as I can, so yeah. Hope you enjoy!
