The Fallen Angel - Underfell

The reset

Frisk stood in front of Sans, he was blocking your way. She wanted to get passed him she could finally return by the surface.
"It's seems someone has been busy leveling up, you killed everyone who stood in your way. Don't you feel any remorse?"
Frisk didn't say anything
"Huh, I guess not, I suppose you have no idea how many pain you have inflicted. You've destroyed families, killed others their loved ones, you've killed Toriel, you've killed Undyne, You've killed Mettaton.....and you've killed my brother..." Sans looked at you with dark eye sockets"
"It won't be easy killing me..."

"it's a beautiful day outside. birds are singing, flowers are blooming... on days like these, kids like you...S h o u l d b e b u r n i n g i n h e l l ."
Frisk tried hitting him, but he dodged the attack.
"You really thought I would just stand there and take it?"
He attacked again, but Frisk dodged his attacks.

Frisks POV

"Why won't he just stop dodging?"
The longer this battle kept going the stranger I felt, a faint voice in my head told me to stop, it tried to reach out to Sans.
"Sans, please, stop i'm still here!!"
I got hit by his attacks. I felt my soul shatter. "Damn" I muttered and collapsed to the ground.

Sans sighted "Sorry kid, I had no other choice.
Suddeny he looked in shock.
"Huh, looks like you know how to reload the files, welp, here comes round two.

Frisk died three more times, and everytime she died, the voice in her head became stronger.
"Please stop taking control of me, I don't want this!"
Frisk grabbed her head "SHUT THE FUCK UP FRISK"
Sans looked confused at her "Frisk?"

"I'm not Frisk, I'm Chara!"
"Chara?"

Frisks/Chara's POV

"Now is my chance"
I swung my knife at him, he dodged again.
"Really kid? You think you can get me off guard so easi-
I swung my knife again, and it finally hitted Sans.
"Game over Sans." I said with a wicked smile.
"No Sans, no.....no...this can't be happening"
The voice started sobbing.

"Kid...I don't know if you can hear me..or if you're playing some mindtrick on me...but....if you're really the kid I once knew.....reset...and *hack* everything will be alright..."

"Sans...don't die...I never meant to do this...I'm so sorry"

Chara laughed hysterical, and with a final slash, Sans turned to dust.

"NOOOOO"
Frisk gained control over her body again, and fell on the ground sobbing to the heap of dust that once was Sans.
"Sans, I will put everything back to normal...I promise"

Third person POV

Chara's soul emerged from Frisks body. "And how exactly are you going to do that?"
Frisk stood up and ran to the shimmering star on the ground.
"You wouldn't dare to do that" Chara said to Frisk with a cold stare.
She sprinted to Frisk holding the real knife "Don't do it, don't you see how much we've accomplished together?"
"I never wanted this!!" Frisk yelled at her with tears rolling over her cheeks
"And yet, you didn't resist when I took over your body" Chara said laughing.
Frisk went to the menu, "I will make up my mistakes, I won't let this happen again.

Chara grabbed Frisk "I won't let you. I want to create my own world doesn't matter if it's with or without you!!"
Her soul went into Frisks body again and made Frisk slap herself.
While they both tried to hurt eachother through Frisks body, Chara accidentally pushed the reset button with Frisks hand.

"Noooo"

Everthing went black, Chara faded from Frisks body and Frisk fell a long way down.
