Hey everybody! I am finally stepping into the Undertale universe with this story (not counting an Undertale song that I wrote, which you can check out by clicking on my username, but only if its highlighted and blue. It's about Asriel, btw.) It's October, and I thought as a Halloween tribute, since October has basically become Halloween month for the internet, I would do a four part Undertale story. Because skeletons. Yeah. Since we have the Halloween theme going here, we can't do this about Papyrus. We can't do it about Toriel. We can't do it about Flow- well actually we can do it about Flowey, but not this time. I'll have something for him later down the road. For now, we concentrate on Sans and Chara. Who else but the freaking embodiment of death and destruction that isn't a flower, and the guy who believes kids should be in hell? AHHHH SPOOOPY! Anyway, enjoy!

Sans sighed heavily when the kid entered the hall. He had been dreading this ever since he had first seen that human, way back in the snowy forest. He hated fighting, but this was inevitable. And unbeatable. Sans was just a monster. When it came down to it, no matter how many tricks he pulled out of his sleeve or however many times he beat him, the kid would win. Humans were just too powerful. One of these times Sans would slip, he would die, and the whole process would continue, only to happen again.

But maybe he could make a small difference. Give the fleeing monsters some time. Just a chance. After all, Sans was all that stood between the human and the destruction of their entire world. Asgore certainly wouldn't beat the kid, so that just left Sans. He had to do it for everyone.

For Papyrus.

"Heya." Sans said when the kid drew near. As he had expected, no response. He continued, "You've been busy, huh?" Again, no answer. Why should he even try? This kid was unreachable. "So, I've got a question for ya. Do you think even the worst person can change? That everybody can be a good person, if they just try?" The kid inched forward, not answering. Probably not even listening. Sans could tell the bloodlust from here, even though the kid's eyes were hidden by shadow. It was like an aura, a presence. This human was out to kill. They were out to kill everything.

Sans chuckled at the slight movement. The disgusting creature was probably just waiting for him to finish talking so it could attack like it had done with everything else. The trick, as Sans had learned through countless trial and error, was to show no fear. When any predator senses fear, they know they already have the psychological advantage.

"All right. Well here's a better question. Do you wanna have a bad time? Cause if you take another step forward… you are REALLY not gonna like what happens next." The human lurched forward before Sans had even finished talking, impatient for death. Apparently they weren't afraid of him either. "Welp." Sans said to himself, remembering the voice on the other side of the door, the promise he had made. The promise he would break. "Sorry, old lady. This is why I never make promises."

He sighed again. "It's a beautiful day outside. Birds are singing. Flowers are blooming. On days like these, kids like you…. should be burning in hell!" Sans opened his magic eye and let loose with a flurry of attacks at the child. He was hoping that, after always attacking his opponents first, the evil human might be caught off guard when they were suddenly thrown on the defensive.

And it worked.

Caught by surprise, the child barely evaded the attacks on its soul, getting hit a couple of times but handily surviving the encounter. Sans sighed. This was going to be tough. "Huh." Sans said to the wounded human. "Always wondered why people never use their strongest attacks first."

And now the battle really begun. The human attacked, an immensely powerful strike that could take down even the toughest of monsters. Sans dodged, but the pure hate scalded his skin as the strike passed by. Now it was his turn. The human found their soul attracted to their ground, and Sans threw a relatively simple series of bone attacks at the human. After failing to survive two or three of them, the human soul shattered right before his eyes.

Then everything disappeared.

But it wasn't over yet. Not by a long shot.

If you liked this, leave a fave, follow, and check out my other stuff. It's mostly Avatar: The Last Airbender at this point, but variety is being thrown in over time. Also, leave your thoughts with a review and be sure to check in next week for part 2! Thanks for reading! Bye!

PS: This ended up being a lot shorter than I had planned, since Sans actually has less dialogue in that opening exchange than I remember and since Chara gets taken down relatively easy for this. Hopefully the rest is longer, but I won't leave being shorter than planned to be out of the realm of possibility for the other chapters as well. This story could end up being much, much shorter than I had planned. Oh well, that means less work. Awesome.
