Undertale: Genocide

Chapter 23: The End

Sans wakes up like falling asleep was apart of his whole act. He winks and breaks out a grin with a shrug.

"Heh, didja really think you would be abl-"

Sans's speech is cut off. Sam's hand moved on their own and sliced Sans across the chest. How did they do that? What exactly just happened?

*You demon.

They have been possessed by the voice in their head, it went against the rules of the underground. They are literally impossible to harm a monster without pushing the fight button first. So how exactly did that happen?

Sans falls to the floor with his eyes wide in shock. His chest begins to bleed across the massive wound. Sans is speechless. Blood begins to drip from his mouth as he looks down at the damage that's been done.

"So... guess that's it, huh? Just... don't say I didn't warn you."

Breathing heavily Sans slowly gets up on his feet. Holding himself together and looking down to hide any emotion.

"Welp. I'm going to grillby's."

Sans shrugs with his own blood tainted on his hand. He still manages a wink and a smile even though he is in pain. He slowly staggers out of the judgement hall. One last sentence echos before he fades away.

"Papyrus, do you want anything?"

A thud is heard in the distance and a massive amount of EXP flow into Sam. Sam has lost control of their body now. Everything around them feels like a big out of body experience. Their LOVE increases and the battle ends.

Their feet walks forward and down a long corridor. There is a massive doorway down here, the obvious direction to go. Before entering the massive doorway however, they keep walking and find a flight of stairs. The stairs lead down and into a room full of brightly colored coffins. Sam opens their mouth without thinking and speaks. But the voice that came out, did not belong to them.

"It's as comfortable as it looks."

They go back up the stairs and finally proceed through the huge doorway. The room is huge. Birds are chirping in the background. Twilight fills the room somehow, holes in the roof maybe? There is a golden flower garden on the floor.

In the middle of the flower garden is him. King Asgore Dreemurr. His back is facing Sam, so he doesn't notice them when they first slowly enter the room. Asgore was speaking to himself, or someone.

"Curious. I've never seen a plant... cry before."

But as Sam slowly approaches Asgore, he hears their footsteps crunching the flowers beneath them. The king turns around slowly.

"Huh? You must be the one that flower just warned me about. Howdy!"

Sam is not in control, they cannot say hi back. Whoever, or whatever is controlling their body doesn't return the friendly gesture either. Flowey warned the king of their arrival? Such betrayal.

"Ah, erm. What kind of monster are you....? Sorry, I cannot tell. Well, we can always-"

King Asgore gets cut off as a battle engages. Whatever is controlling them has the ability to fight anyone they want. They are powerful indeed. When the battle begins, Sam notices one major detail. The MERCY button is completely gone. No more chances.

"Now, now. There's no need to fight." The king's sweet voice seems to be having little effect. "Why not settle this over a nice cup of tea?"

Without the need of pushing buttons, Sam's body moves on it's own and stabs Asgore. Instantly doing enough damage to kill him. Asgore cletches his chest and falls to one knee.

"Why... you..."

Asgore's face fills with shock as a ring of deadly petals surround him. Flowey's deadly petals. Flowey brings all petals crashing down upon Asgore, delivering the final blow to him and his monster soul. The soul explodes into a million pieces, and Flowey emerges from the ground. Floweys face is covered in a worried smile.

"See? I never betrayed you! It was all a trick, see? I was waiting to kill him for you! After all it's me, your best friend!"

Floweys face transforms to resemble a goat. Not quite Toriel, but not quite the goat King Asgore. Its someone else, somebody Sam has never met before. But maybe the person controlling them have.

"I'm helpful, I can be useful to you. I promise I won't get in your way. I... can help."

Flowey begins to cry as his voice gets all childish and shakey. Its not his usual menacing self. This is... different. Maybe who he used to be?

"Please don't kill me."

Floweys face turns into one of horror as Sam's hand raises the knife. Multiple times Flowey is cut into two. Each time, the flowers broken face becoming more horrific. Sam... didn't want this to happen. They just wanted to go home. What have they become?

The room turns pitch black, and everything becomes a void. There ie nothing left. This is no one left. Until suddenly, Sam gets control over their body again. They look up to see a human floating in the darkness with them. The human is wearing a striped green and yellow sweater. Their hair is just like Sam's.

But the most surprising factor, is their voice. They sound just like the voice that was in their head. This must be the source of it all, the source of the evil that's been forged into their soul.

"Greetings. I am Chara."
