Storyshifted - (SS!Chara X Reader)

CH6: Familiarity

(just realised how different Frisk's personality is going from chapter 1 to 2/3, lets just say chapter 1 was from a different pacifist timeline and after that is the current timeline, except in the current timeline chapter one happens except with Frisk having her current personality)

Chara's POV:

I slowly opened my eyes, but realised I wasn't in the empty black void, waiting to be reset back to the start of the run. I was still in the last corridor alright... but not dead. There wasn't much blood either, only a bit from the attack Frisk did to my left arm. I also noticed that Frisk was quite far away from me. I was all the way at the end of the corridor, near the doorway to the palace, while Frisk was back in the middle of the corridor where that one misplaced pillar was, looking enraged and confused at the same time. I was just as confused as her, as I looked down, and noticed my soul was floating in front of me... but blue.

Blue soul magic... only the king knows how to do that type of magic, yet he was likely still in his castle, unaware of anything thats going on. Its been this way for every run now... but no one else knows blue soul magic in the underground... except the king's brother, but he was long gone by now.

My eyes then shifted over to a black shadowy silhouette that had seemingly appeared out of nowhere. It wasn't here when we we're fighting, thats for sure.

The silhouette looked similar to the one I use on Frisk and Y/N. Of course, only Y/N gets surprised from it anymore, but this silhouette definitely surprised her just as much as mine did in the first run.

I looked closer at the silhouette as it slowly walked in front of Frisk, attempting to attack it with her chainsaw, however being dodged easily by the shadowy figure. The silhouette seemed to resemble a human, but the only humans in this place we're me, Frisk, and... Y/N... | Chara: ...Y/N?

The silhouette then revealed itself, and... Y/N was the one who approached the megalomaniac... was he out of his mind? | Chara: What are you doing?! Your going to get yourse- | Y/N: I'll be fine, Char. As for you... Frisk... | 'Char'...? Only Rei called me that... and also, was he actually fighting her?!! He's going to become a pile of rotten meat... what was he thinking?!

Frisk: Ha... hello again... friend. You should step aside now, I wouldn't want to hurt ya, right, best friend...? | Y/N gave Frisk a stern expression, not moving an inch. | Y/N: You killed everyone. Like a genocidal maniac. You tried to kill me, and you still call me your "friend"...? Believe me when I say this, Frisk... Y O U R   G O I N G   T O   H A V E   A   B A D   T I M E . | Frisk stepped back in shock, and a new feeling... fear. I was extremely surprised too, he used my way of talking... wow, was he learning from me or what? | Frisk: ...One last warning. Step aside. I need to finish the job. | But Y/N didn't move. I tried getting back up to help him, but I got slammed back down from the blue soul. Did Y/N know how to... use it? Only the royal skeletons knows how to use it, as I thought earlier, but... apparently not...

Y/N: I'm not moving. You killed everyone, even Papyrus. He helped us, yet you killed him, with no remorse. I'm surprised I made it out of the ruins. The amount of dust you had on your body when leaving there was way more than how much one skeleton would have became. Heh... tibia honest, I don't know why, but I felt like me and Papyrus had some sort of bond before. I sensed something between us, as if we knew each other before, maybe as friends or something. I don't know why, but thats just what I felt. And I sense a similar feeling with you. And we're no longer friends. So... maybe, somehow, in a past I don't remember... we were friends. | Frisk and I stared at each other, both thinking the same thing. Did he somehow learn about the timelines...? But how would he? Only me, Frisk and that flower was aware of it, and I wouldn't be surprised if the flower was compost by now. Not a single word came out of either of our mouths.

Y/N: Eh, who am I kidding. We just met, yet I feel like I remember him as a brother. Either way, I guess we're supposed to be fighting and stuff, so, uh, one second, lemme remember my monologue real quick. | Frisk and I were still frozen in shock from earlier, but a chuckle came out of me as I realised what he said. 'Tibia honest'... a bone joke me and the king would always share. He must of been a great joker while up in the surface.

Y/N's POV:

I looked at the frozen Frisk, slightly confused on why she looked so shocked, and why she was sweating so much. However, I didn't show the confusion on my face, as I slowly remembered what I was supposed to say. I don't know how, but I feel like this was meant to be my job, to confront humans at the end of a corridor. Maybe past lives really are a thing. But who knows. All I know is that this threat needs to be neutralised, friend or not. | Y/N: Alright sorry, took me a moment to gather my thoughts, but here we go. | The room suddenly turns black and white, which although I've never seen before, gave me a sense of familiarity. I learned from a book in the 'librarby' that this is where combat commenced in the underground, which was odd, but I wasn't going to try counteracting that.

Y/N: Its a beautiful day outside. | I looked back at Chara, which, had another shocked expression, but looked back at Frisk, sharing the same face. What's so surprising about a single sentence? | Y/N: Birds are singing, flowers are blooming... | I heard a chuckle come out of Frisk's mouth, as I saw her ready her chainsaw. Was it intimidating, yes, but I wasn't just going to back down. I was the last stand of this place. If I fall, the underground falls along with me. Chara's too tired, and considering the king did nothing to help Chara, I doubt he would do anything against this megalomaniac. | Y/N: On days like these, people like you... | Everything turns black for half a second, before everything reappears, except I can now see a red soul in a rectangular box in front of me. Must be Frisk's. I felt my right eye glowing with a shade of blue and orange, and a slight amount of red. This was it, the true final battle determining the fate of the underground, as the flower called it. I was filled with integrity, bravery, and determination. | Y/N: S H O U L D   B E   B U R N I N G   I N   H E L L.

Btw, AUs are canon in this fanfic, which is why you see resemblances of classic sans. You might be able to guess the plot twist, but honestly I'm not a person of giving subtle hints.
