The most powerful (Female Frisk x Male reader)

Inner peace

Your POV

I wake up to the comforting darkness of Darklord's inter-dimensional reality. "So how are you feeling (Y/N), better?" I look at him and wonder if it was all a dream. "Yeah much better now, but is it true that you're my brother?" I mentally facepalm for being so blunt. "Yeah it's true I didn't realize it at first either, but now that we both know I want to say something that's been on my mind. (Y/N) I-I told you to stay strong for me but it was really for yourself, because I knew that my soul is unique. It's the only one of it's kind, even more rare than yours. My soul allows for me to heal very rapidly, but to do so I had to come here and when I did I lost most of my memories and became this thing, my wounds are still here for some reason that I can't explain which is why I can only come out for two hours. This place is keeping me alive, so if I was to stay out for any longer, I am in pain and I risk myself dying so as time went on I messed around with my soul's powers and learned that I could open portals to different dimensions, but when I tried to go to a different dimension from UT directly i couldn't." I looked at him sadly but I noticed something changing about him, he was looking more human. I asked to see his wounds and saw that they were closing up slowly, but much faster than any I've seen. "I know it looks bad, but hey at least I'm still alive. But seriously (Y/N) you should get back to Frisk she's waiting for you." He opens a portal and I see Frisk on the other side with FS Chara on one side and UT Chara on the other side both of them were comforting her. Shadow was in the kitchen getting some ice cream for Frisk. I look back at Zero, "Hey listen I'm sorry for all the trouble I've caused you, I just... I don't know I guess you could say that being the middle kid I just wanted to 'brother' you." He groaned and facepalmed at the bad joke. "Seriously though back then nothing had been the same without you (S/N) never got to know you, I was traumatized and mom and dad, well never mind just listen you were missed. I'll see ya."

I walk through the portal and Frisk has her head in her hands, Shadow drops the ice cream making the girls look up and they all see me, only Frisk jumps up. "You idiot what happened why didn't you tell me you weren't feeling right?" I chuckle at her, "I was feeling fine until just then, and it turns out that Clara did it to me because of her soul's trait, Hate, even the most kind people can fall under her influence, I fought it and well you saw what happened." Everyone fell silent you could hear a pin drop. "It was the thought of you that let me fight back and well let's just say I've found someone who I haven't seen in a very long time." Everybody looks at me in suspense, "My brother, I thought he died a few years ago, but it turns out that Darklord is my brother, his real name is Zero." Everybody just smiles at me. "I'm happy to hear that." Frisk says. I just smile back at her and pull her into a kiss it lasts for a few seconds before we both need to catch our breath. "Come on you two get to bed I think you need some rest, Chara do you need a ride home?" Shadow asks. "Yeah, thanks for the offer." UT Chara says. "Okay me and the two Charas will go and you two can have some alone time."

Time skip

After they left, me and Frisk were sitting on our bed and talking until I leaned down to Frisk's baby bump. "Hey there it's me Daddy." I say quietly and in response Frisk feels a kick. "Hey you be a good girl and let Mommy sleep now okay." I say gently.  A small kick was the response. After Frisk fell asleep but I laid awake for a few more minutes until I heard a noise come from the kitchen. When I got down there I saw broken glass and a man, I immediately got ready to fight, I wasn't about to lose someone else to a criminal. He turns to see me and pulls out his machete and tries to slash me but I catch it in one hand and pull it out of his hands, "This is a very nice little toy you've got here but I'll show you a real weapon." I throw the machete down on the ground and summon my scythe, "This is a real weapon, dangerous, nice reach and you are able to kill in a single attack. Now if you value your life at all you will stand at the door, leave the blade there, and will go with the police when they get here." he does as I say and gets taken away. Just then Frisk walks down, "(Y/N) what happened down here, did someone break in?" I tell her the truth and say that he didn't get anything, I stopped him and had the police take him away with no blood spilled. With that her peace of mind was restored and she went back to bed. I don't because I was wide awake now, so I stayed in the living room and meditated to recharge my energy.

No POV

As you meditated you summoned strength that you didn't know you had and it made a body so that you could see it. As you opened your eyes you saw a young boy wondering where he came from you asked. "Me oh I'm from you, you summoned me here when you were meditating your strength was overflowing so to stop it from overwhelming you I took it to make a physical body. You guys don't have many books do you?" You were dumbfounded you summoned this kid out of nowhere. "(Y/N) who's down there?" Frisk shouts from upstairs. "It would be better if you came down here because I'm not even sure what to do." The next thing you know the kid's saying hi to Frisk and is asking about the baby. "Okay that's enough, time for you to go. Or at least lay down on the couch and go to sleep. Me and Frisk are going to go upstairs and get some rest too." You then proceed to pick Frisk up and carry her upstairs to bed. While you do that the kid continues to look around and finds a torn up notebook held together with a few strips of leather and he reads it and soon realized that it was your journal where you put everything in from your smallest thoughts to your biggest dreams and everything in between. "Oh god I shouldn't be reading this I'll just put this back underneath the couch." Soon he falls asleep too and for a little bit everything and everyone seemed to be at peace.
