You pov

You reseted for the 1000th time. You just straight up did genocide. No pacifists, no neutrals, just pure genocide. You had possessed frisk, killed Chara, killed everyone. You just smiled through it all. The dust flowed down your hands and knife. Your trusty knife. Why did you do this in the first place? Well, you ARE a demon after all. Your lust for killing won't be fulfilled anytime soon and it won't be. You killed monsters and blamed it all on frisk. It wasn't long until HE found out that it was all you. HE tried to stop you but he was just too WEAK. Pathetic little comedian. He didn't even try to save his own brother. He just watched as you sliced his head off and turned it into dust. You had finished another route as Chara appeared, scared. You smirked as you grabbed your knife and stabbed her repeatedly. Frisk was pleading for you to stop. He (yes frisk is a boy) tried to stop you multiple times but you always win. You chuckled as your tail swished side to side. You also killed him and you went to the reset button. Your hand hovered over it and you pushed it...

Something was wrong. The reset button won't work. You were confused as you pushed it again. Nothing happened. You got angry and smashed the reset button. The void around you glitched. You were shocked. This didnt happen before. Now, you can't reset. What was happening? The void stopped glitching. You were falling. Falling down a endless void. You tried to fly with your wings as you flapped them but, you were still falling. You finally fell face flat on the floor. You groaned as you stood up. You looked around you. Still void. You tried loading your save. You can't. You looked beside you and you saw a white blob with some hints of red. It was coming to you. You got your knife ready as it became closer and closer. Tap tap tap... It's footsteps echoed throughout the void. You finally saw who it is. It was HIM. He looked, odd. He still has the slash on his torso and his clothes were all white. There is a glitch on one of his eye as he held his brother's scarf. He glared at you as you smirked. "So, greetings comedian. Missed your pathetic brother?" He growled as he sat down. You tightly held your knife as you dashed at him. You stabbed him.

...

Nothing happens...?

You stabbed him multiple times and still, nothing happens. "Heh. I thought you already know that here, in the void, nothing can die and nothing can heal. I must have overestimated you." He said. Now it's your time to glare. "How did you even get here?" You hissed. "Well, why am I gonna tell you?" "JUST TELL ME!" "nope." "Grrrr...." You tried to reset. Nothing. You tried to load. Nothing. You can't escape. "Buddy, your fate is in my hands now. I control this void and I wont let you reset, load or even get out of here so your stuck with me here for eternity until either of us rot in this void but I can assure you, your the first one that will." He smirked. "The resets will finally stop. No more killing, no more fighting, no more possessing." He laughed with tears on his eyesockets. "All of my suffering has finally paid off." He sat down, chuckling and sobbing happily. "You know what?" He trapped you in a cage made of bones. You struggled and tried to break the bones but, it didn't break. "So that you won't do anything, you have to stay there and rot forever" his eyesockets went dark. Just then, frisk appeared. He also had a few glitches on his hair. "Sans? What's happening? Are you okay?" He said as he examined his cut. "Nah kiddo. It's all gonna be over now." Frisk looked at the cage and smiled. The both of them chatted while you just sat there.

Timeskip...

You had seen some sanses appear on the void. They always ask Geno of why you are here and he just says the same thing. "To end our suffering". You didn't really talk much. There ain't much to do in this void. You did became a little crazy but not that much. It felt like years since the three of you are in here. Your soul was slowly getting consumed by hate and Insanity but you didn't really mind it. Frisk has been trying to make you good but, it always doesn't work because he is a failure. "So brat, how's it going there?" "..." "Heh... Not much of a talker now eh?" You just stayed silent. You still felt pain in your soul but you were used to it now. It doesn't really matter now, does it? He chuckled as be walked away from you. Weeks had passed and you finally snapped. You growled and destroyed the cage of bones open. The two were shocked as from hid behind sans. Your form was changing as you crawled to them. Frisk was shivering as sans had his eye glowing. You heard bones cracking. Your teeth felt sharp as your nails grew longer and bigger. You went bugger and bigger as spiked appeared on the top of your head,spine and at the back of your hand. Your eyes became a dark blood red and green,poisonous ink flowed down your mouth. You roared and charged at them. Sans tried to levitate you but failed. He's still so dumb. Doesn't he know that demons have no souls? He sent bones towards your direction as well as blasters. You dodged them all and slashed them. They flew back and smashed the walls of the void. You growled and opened a portal to a different au. You went in and they chased after you. Sans ate a hot dog to heal on the way out as you ran and attacked every monster you come across.

FELL'S pov (yep ;p be proud)

I was just walking around after a rough beating thanks to papyrus. I heard growling and k turned my head around and saw a huge demon thing. It slashed and killed every monster it came across. "WHAT THE F*** IS THAT THING?!?" I yelled and ran to it. It saw me and slashed me. I got levitated and I saw Geno. Before I can say anything, "look fell. We need help to destroy that demon. C'mon, let's follow her" he dragged me as the huge demon opened another portal and went through. We jumped with it as the portal closed. It did the same thing it did to my au. WHAT IS WRONG WITH THIS JACKA**?!?

Reader's pov

I was going to visit Tori until I heard some screams. I teleported to snowdin to see a demon. I widened my eyesockets as it looked at me. I tried blasting it but it didn't even leave a scratch! It swatted me and it was gonna kill me until a bone blocked it's claws. I looked and saw Geno,fell and Aftertale frisk. The bone went to me and I rode it until it got me to the three. "We need help to fight this demon. C'mon." Geno said, not wasting time as he ran and I followed. We all jumped through a huge portal created by the demon. We are now in Underswap.

I think I will do a part two to this and yes, the transforming part is trashy. Ok bye p chips! :3
