[Undertale] Sans X Reader - Repeat, Eternally

Chapter 80 - Wee, I'm inside you?

I'm gonna try to be a minimalist and just talk to you when necessary. Otherwise, I probably wouldn't be able to narrate your existence.

You thank whatever almighty power that shut the voice up, and turned to Devil!Sans.Wow, you're really hurtful in gener- okay, damn it. I'll stop! Anyways, as you turned to Devil!Sans, the sound of a Gaster Blaster shot through the air. The beam hit Devil!Sans, sending him flying into a tree. You turned, your entire body shaking. Just a centimeter more, and that would have been you...!

" S a n s . W h a t d o y o u t h i n k y o u ' r e d o i n g , c o n v e r s i n g w i t h a h u m a n ? " It was Devil!Gaster. His shadow hung over you, imposing and powerful. You felt like you were turning into a puddle of mush. " I d i d n ' t t h i n k y o u ' d b e t r a y t h e r u l e s l i k e t h i s . "

"Father....~! This human will help us...~ They're absolutely wonderful...!~" Devil!Sans gave his father a gentle smile, which was shocking, as his father had just blasted him into a tree.

" T h i s p a t h e t i c t h i n g c a n ' t h e l p a n y o n e . "

"Wow, thanks." You muttered, under your breath. This caused Devil!Gaster's attention to turn to you; there was a glare in his eyes. You backed away, but were surrounded by Gaster Blasters in an instant.

" W a s t h e r e s o m e t h i n g y o u w a n t e d t o s a y ? "

Hey, don't die on me now. You'll go through a true reset, and those things are annoying as hell! You haven't saved in like a year or something, so you can't reset! No matter what!

"Can't you do anything?!" You yell, which causes the Gaster Blasters to ready their attacks. They fired their lasers, and you shielded your face behind your arms..

Pink Soul Special Activation: Nullification!

Your soul emerged from your chest, and instead of grey, it was now a bubblegum pink. You stared at it, in absolute despair. Your soul color could change?!

Yeppers. And, I have more where that came from! I can change your soul's color to 142 different things; they all do lots of different things. If... if that makes sense to you. Anyways, I have a special attack that can't be beaten. Almost literally; and it's called Special Activation!

Devil!Gaster was confused, but he readied another blast.
