The skeletal monster snarled as he gazed around, scanning over the dust-covered ground as if he'd somehow find another victim in the mess. Once he'd determined that there was no one else to kill, he stood up and faced his "master", who was watching from the edge of the tree cover.
   The half-melted figure gave a small nod of acknowledgement before moving towards the crazed monster, surprisingly calm despite the beast's previous actions.
   "Great job, Sans. That should be the last of those petty monsters." He crouched down next to the skeleton, resting a single hand on his shoulder.
   The feral gleam suddenly faded from Sans's eyes, the spiraling neon blue and yellow light in his left eye vanishing slowly as he started to regain consciousness. "Wh-Why did you m-make me do thhiss? Wh-What wass thhe goal herre?"
   The mysterious figure chuckled. "Those monsters were weak, Sans. They wouldn't have been of any use to Monsterkind anyway."
   Sans narrowed his eyes, his left eye turning ice-blue as he stared at the other monster coldly. "No. You'rre wrrong, Gassterr. We didn't havve to kill thhem."
   Gaster's gaze slowly left the skeleton and instead focused on a rapidly approaching figure, a sick smile spreading across his face. "We aren't even done yet. Here comes another."
   Sans turned around to look in the direction Gaster was referencing, his soul skipping a beat as he instantly recognized who the monster was. "No... Not herr... Pleasse, not herr..."
   "Oh, so you know her?"
   He would know that figure anywhere. Tiny frame, fluffy white fur, long ears, small blue and white wings, a trademark blue sweater, a tail tipped with blue feathers... and large, expressive eyes.
   Sans's eyes went wide as the monster started running even faster at the sight of him. "Ssorra! No! Get outta herre!"
   Gaster snapped his fingers, his magic taking back control of the skeleton's mind just as the dragon came screeching to a halt at the edge of the trees.
   "Sans!" Sora squeaked. "What have you done to him??"
   Sans stared at the fluffy dragon blankly, the blue light in his left eye becoming intermixed with neon yellow once more, a spiral becoming visible within the light-flooded socket.
   Sora's ears pinned back as she noticed splatters and smudges of dark red all over the skeleton, the most chilling being across the right side of his face and across his t-shirt. She shuddered as she realized that the stains were of blood.
   The skeleton lifted a clawed hand, which was also covered in blood. Sora looked to the figure behind Sans helplessly, her eyes flashing pale gray with fear. "Why isn't he talking to me??"

   Gaster chuckled eerily, causing Sora to flinch. "Sans is no longer here. I have control of his mind. He will do anything I command him to do."
   Sora took a step back, her fur bristling up and the ridge of dark-blue feathers along the back of her head standing on end. "What are you going to make him do?"
   Gaster didn't answer her, but instead leaning down so that he could whisper something to Sans.
   "Sans. Kill her."
   The skeleton's gaze locked onto the angel dragon, a low growl rumbling in his throat. Sora stood where she was for a moment, frozen with fear.
   Sans suddenly darted forward, snarling wildly as he tore after his target, who bolted away at that same instant.
   Sora ran as fast as she could back towards Snowdin, screaming as she fled from the skeleton she once knew and loved so much.

Ok, quick note on this. I was originally gonna record a speedpaint of this, but I kept blowing it off. I need to get a screen recorder, but I can't ever remember my heccing apple ID password and I forget to talk to my mom about these things, so yeah... :/

Just thought I'd say that lol
