Crazy For You •°•Sans X Insane!reader•°•

°•°Distrust°•°

"I thought that turning you insane was a way to get you back... I missed you... And now you come home with this much LV.... I don't even know if I could trust you anymore...." Sans said and looked at you with an angry blue with flashing gold eye.

"S-s-sans I can ex-" you said but couldn't finish when he pinned you on the wall with his magic.

"Now I'm gonna ask you a question.." He said as he slowly stepped closer.

"Do you think that even the worst person can change... Even if they just try?!" He shouted at you and you choked the word 'yes'

"Well.... Here's a better question" he said and snapped his finger and 2 faster blaster appeared.

"Do you want to have a bad time?!?!?!" He shouted and the blasters were ready to charge... Until... You lost control.

"YoU CaNt HurT Me SanSy~" you said while glitching. Your eyes went blood red and your clothes turned to a green sweater with yellow stripes.

"Chara.... I should've known..... YOU TRAITOR!!!" Sans shouted and Chara appeared behind him.

"But... Sans.... I'm right here! That's not me!!!" They shouted and when they turned back to you.

Your hair was short and brown and your eyes were dark and had black ooze coming out with red dots as pupils.

"OH ChArA ItS OnlY BeeN A FeW YeArs AnD You AlReAdy FoRgOt ABouT Me" you said clutching and Chara's eyes widened.

"Its the demon inside of me.." She said and Sans suffocated you with his magic.

"Okay. I don't want to hurt (y/n). But I want to hurt that damned demon child who made me suffer the past resets.." He said and summoned the Gaster blasters.

"I'm sorry (y/n) but I have to do this" he said and he blasted you.

*HP decreased by 10.

"Now.... The only way to do this is to kill you and we'll RESET" Sans said but you got out of his grip and lunged at him.

'Slash!'

He fell down to his knees and everyone gasped.

"W-well, I guess its time for me to dust-appear huh? Heh heh" he laughed and turned to dust.

"You little punk!!!" Undyne shouted and summoned spears around her.

"Your going to die!!!" She shouted and aimed the spears at you.

'Dodge' 'dodge' 'Slash!'

You slashed her and her HP decreased by 50.

"Gah!!!" She said angrily and aimed more spears at you.

'Dodge' 'Dodge' 'Slash!'

You slashed her again and it decreased by a hundred.

It went like this for an hour until she gave up and turned to dust.

"My child, I'm sorry" Toriel said and the battle started.

She summoned fireballs and aimed it at you.

But you were still fast enough to dodge.

Soon enough you killed her and she turned to dust.

This went on and on. Until Chara was the last one to fight...

Frisk was hidden upstairs and they protected her no matter what.

It was quite easy to defeat the taller skeleton and he died before a minute even started.

"You'll pay for this!!" Chara shouted and she summoned giant red knives and threw them at you.

You dodged it and lunged at her. But she dodged it.

*you ate the nice cream! HP fully restored

You lunged at her again and she dodged it again.

"I'll make you pay!!" They shouted and summoned knives and aimed at you again.

One hit you and your HP almost reached zero.

'Dang those knives are sharp' you thought to yourself and after that you lunged at her then.

'SLASH
