A Final Boss Awakens!

[Sans]

He nodded his head, the eyelids of his eye-sockets sliding downward as if he was about to fall asleep on the spot. Despite this appearance, however, his concentration was being used entirely on listening to what Desco was saying. He analyzed every word she spoke and processed it in his head, trying to figure out what he can learn from her.

Honestly, he was glad she was weakened. If what she said was true (and given her mannerisms, his guess was as good as anyone elses,) then she had the power to destroy the world. He resisted the urge to feel for the chipped part of his skeletal torso, the scar that lined his collarbone down to the left part of his stomach. He wished he did, though, as almost immediately after, he felt a sharp twinge of pain shoot through his chest that started right from where his scar was. He visibly limped in his next few steps, though he made no noises and, soon enough, he was back to his original slumped, uncaring, energy-conserving posture.

Still, the thought that this Desco could very easily repeat what she had done almost made him tremble. One Frisk was bad enough, but there wouldn't be anything he could do against two. Regardless of where he was, he was at least glad the tentacle monster no longer carried the same power she once had.

Unless she was fucking with him, of course. That was also a possibility.

He forced out a chuckle as she recalled meeting Guu. From the way she spoke about the Princess, he was willing to bet the leader of Ambrosia held considerable power to reign in someone like Desco and keep them on a semi-tight leash. Or Guu was just as potentially psychopathic as Desco was and they just shared similar interests and child-like hobbies to warrant being friends.

He was just about to ask another question when one of the penguin-surfer-dude things began to speak up again. It had only been a few minutes since he had first heard them speak, and already he had a visual of what a washing machine with a brick thrown into it while it was running sounded like. Despite that, though, one part of his speech caught his attention, causing his eyes to widen a tiny bit: Guu's expressionless face.

"wait, doodette, hold the phone. what do you me-"

Then, time seemed to move in slow motion. In as little time as it took to breathe, the once harmless, child-like alien had screamed at the top of her lungs. She had then pushed herself up into the air with her tail, towering over Sans and the Prinnies. The reptillian-looking, demented yellow eyes all moved to glare at the offending Prinnie.

Then, as if he was in some form of horror movie, many massive, purple and red colored tentacles appeared behind her. One sprang forward, zooming past the skeleton.

The singular tentacle wrapped around the legs of the Prinnie. Before the comedian could even blink, the Prinnie was already sailing towards a nearby building. Upon impact, a loud explosion rang out, followed by bits of brick and mortar shrapnel flying around them. Several civilians immediately scattered from the scene, and despite there being a pretty huge crater where the Prinnie had died, the building was otherwise intact. 

The whole time, however, Sans simply stood there. His eyes were as small as pin-pricks, and his smile had slumped a small amount. He looked back at Desco, who was now smiling as if she didn't literally just kill one of her own minions in a fit of childish rage. The sudden shift of mood made him giggle a bit, which knocked him back into his senses and reverted back to how he looked previously.

"that was, uh..." he began to say, his words obviously coming a lot slower and more carefully thought out, "quite an explosive way to blow your top there."

He took a step back, his bones tightening in anticipation.

"but, uh... what did he mean by 'expressionless' and 'creepy face,' exactly? and, uh..." He glanced back towards the hole in the building, smoke filling his nosehole and almost making him cough, "why was your reaction to toss him into that building and almost kill a bunch of people? just sayin', it's a little over the top, ya know?"
