The most powerful (Female Frisk x Male reader)

The broken-hearted rule

Your POV

We walked out hand in hand into a ruined laboratory "What happened here?" I ask. Frisk looks back at me and tells me what happened after I was sucked into the void.

Flashback with Frisk's POV

"...every skill known and unknown." Gaster finished his explanation, but I was still in tears. "Okay but how do we get him out of there?" He looks at me, then to Sans, and back to me "There are two known ways to enter and exit the void. The first is to do what I did, and fall into the Core as it is working on startup, the second is to use that void gun but the gun is broken and only (Y/N) knows how to make it. The ways to exit the void are much harder to do. The first is to have someone take your place as the void's prisoner, but that will almost certainly lead to them losing their mind, and the second is to pass the judgement of the enforcer that passes through every billion void years and have enough strength to open a new portal from inside the void, before he comes again. Both of those options are nearly impossible now."

Time skip 1 day 

Gaster began work on a new device and with his and Sans' knowledge of the exact situation of when Gaster fell into the Core they worked day and night on the machine only three days later would the machine be working. Then on the fourth day some people came in and attacked them Gaster finished but the lab was destroyed.

End of flashback

"If you go out of the safe room you can see what the has happened to the code of the world." She said. I walk out and see what can only be described as hell on earth. The buildings are blazing, streets are torn up, entire sections of the ground are pure black, I look out and wonder how all of this happened in four days for them. Then it hit me like a train, "Frisk where is Lily, please let me know now that she is safe." Frisk looks away and I see tears running down her cheeks. I go wide eyed, "My little girl is dead, how, how did this happen? FRISK TELL ME HOW DID OUR PRECIOUS LITTLE LILY DIE!" I yell as I feel myself losing control of my mind and my body. "It was a group of terrorists, they attacked Toriel while she was watching Lily for me. They left a note next to Toriel's dust and Lily's bloody body. The note read 'Our first target is dead now bring (Y/N) to us or this will happen to more monsters." I couldn't believe what I had just heard I fell to the ground and I couldn't think, my mind was filled with rage. I instinctively transform into the half dragon body and flew away at a near super sonic speed. I approached a huge black building in the center of the city and I stopped in front of it, not aware of what I was doing I created five giant cuts in the side of it and watched as it fell. I wasn't prepared for what I did next, I flew farther away and eventually made it to an open meadow where I landed. "Well at least some beauty is left here wouldn't you agree Frisk?" I look back for an answer and realize I left her there at the lab. I fly back faster than I ever had before reaching Mach 2 and when I got there I saw I was too late by a second. A man stood over Frisk's body holding a knife dripping with blood. I lost my mind and annihilated the man, the lab and the mountain we were under. I look around like a lost puppy for hours afterward until I reached my house, I walked in and saw Lily laying in dust, I looked at the sight for three minutes, holding back the urge to vomit. I finally went out to see five men walking the streets. "Hey guys look who it is, (Y/N), the coward." I look at them with a feeling that I know all too well, emptiness, the leader runs up and smashes hi baseball bat over my head, and I look up, unfazed. "To hurt me you are going to have to try a little harder than that." I say coldly I show them my real strength and with a single touch I sent one flying back, far, his screaming is lost for a minute and then we heard it again from behind us approaching at a high speed until he hits the ground in front of me, his body popping like a balloon. The others just stare at what was their friend. "Now anyone else want to try me, I need to let out some steam." They stare and drop to their knees and bow down to me. I start crying because the sight reminds me of when I would play kings and castles in my old dimension "Damn you idiots, get the f**k up. I AM YOUR KING NOW AND YOU WILL DO WHAT I SAY OR ELSE YOU WILL DIE!" They stare for a second then get up. "Now give me all of your weapons." They do what I say and I notice a machete, pick it up and slice all of their heads off at once. I go back to where Frisk's body is and grab her ring. I touch the save stone and a menu appears with two buttons.

I look at her body and hit reset knowing that it may wipe me from the existence of this universe and since I am from a different one I won't wake up from this.
