Little Nightmare (Nightmare Sans (Dad) x Luna (son)

Chapter 13

*Le nother time skip to when Luna is 16 now yay!* ( What Melody looks like up top. Art by me 😁)

Luna had turned 16 previously. Nightmare didn't have a large party for Luna or anything just something small for just the two of them. Luna didn't mind, he had finally mastered his abilities thanks to the training. Now both Luna and Nightmare were in the training arena getting ready for a battle.

"Father if I can either hit or make you move from that spot you will start bringing me with you when you leave and let me help you. Deal?" Luna called smiling. "Sure kiddo but if you can't you will continue to stay here in the castle and train" nightmare said smirking and luna nods. "Deal"

The two got in their fighting stances ready. "You can have the first move son" Nightmare called, as his tendrils flailed around him in a calm manner. Luna nods and closed his eyes taking a deep breath his bones and skull turned black, the crescent moon on his forehead going through the faces before stopping at a silver-colored crescent moon with a violet outline. Luna than opened his eye sockets again as his eye lights changed to a silver crescent moon in his left eye socket and a light blue light. He looked at his father smirking. Nightmare expression went to surprise, before smirking figuring luna's plan.

Luna used his scarf ends as tendrils and sent them at his father. Nightmare easily dissected luna's scarf with his own tendrils. "Really son is this all you got out of all those years of training?" Nightmare called chuckling darkly. "You haven't seen nothing yet----father," Luna said as he teleports in front of his father and looked into Nightmare one eye smirking. Nightmare flinched back and chuckled avoiding his son's gaze.

"Trying to put your own father to sleep huh? Nice try kiddo" Nightmare said and summoned another tendril and sent it at his son. It wrapped around luna, lifted him off the ground and flung him back to the opposite side of the arena.

Luna skidded as he caught himself and smirked before he teleports to his dad going behind him and used his scarf to wrap around his dad. Nightmare deflected with his own tendrils again as the two pushed against each other both smirking. "you've gotten a lot stronger Luna" Nightmare said smirking "thanks dad I've been training hard" Luna replied smirking back at his dad.

The two continued to push against each other both not taking their eyes off the the other. Luna summoned one of his tendrils and had it hidden behind him. He had it stay somewhat hidden as it slithers up and behind one of his scarf ends towards his dad. What he failed to notice was that Nightmare had the same idea.

Luna was able to get his tendril behind his dad as he planned on tripping his dad. While Nightmare planned on picking luna up. Luna smirk widened as he jumped back hooking his tendril behind his dad's ankles and pulled them forward catching his dad off guard. Nightmare yelled out surprised as he fell backward. His tendril missed luna, but then reached for him again and wrapped around him catching him making it so he couldn't get out.

"Haha! Got you dad!" Luna laughed out as NIghtmare sat up and looked up at Luna and chuckled "I also have you son" he chuckled before he placed Luna down and stood up. "Good job kid. You win a deals a deal, I'll inform you next time I go out and you can come with"

Luna smiled happily while Nightmare smiled at him. Nightmare never really used his full strength on luna. If he had Luna would not have won. Nightmare watched as Luna left to go get cleaned up and into some clean clothes. Before sparing with Nightmare he was training. NIghtmare left and teleports to his room to do some planning for how he would bring Luna with him to take over his first AU.

*Luna's prov*

I saw dad teleport away, as I left the arena. I don't teleport or open portals often as it drains too much of my energy. 'I should probably work on that' I thought on ways to store energy so that I don't run out when I teleport or open a portal. I walked into and through the dark castle halls making my way to the large staircase that leads up to the upper levels. My room was on the same level as dad's room I was down the hall from him and on the other side.

I walked up the stairs and down the hall towards my room. Once there I opened my room door. My door wasn't black like most of the other doors. It was a dark navy blue, purple. With a silver crescent moon top center. I opened my door and walked in closing it behind me. I sighed and removed my scarf and hoodie tossing them on my bed before making my way to the bathroom. Once I was in the bathroom I undressed and tossed the dirty shirt and shorts in the basket behind the bathroom door. After that, I grabbed a dark blue towel hung it on the hanger on the wall by my shower as I got in. I turned the water on warm and let the cold slowly warm up while it ran down my skull and acking bones.

I stood under the runing water before i grabbed my scrub and soup and started to wash myself. I used shampoo conditioner on my hair before washing my face and turned the water off once done. I grabbed my towel and dried myself off before wrapping it arounf my hips(?). I brushed my teeth and combed through my haor before shaking my head to fluff it a bit. I smiled and walked out of my bathroom and over to my closet. Which was right next to the bathroom. I opened the doors and walked in as it was a walk in closet. I go over to the dresser and grabbed a pair of loose black jeans, before going to grab one of my t-shirts that was blue-teal.

After getting dressed I walked out of my closet closing the door behind me, and walked over to my bed and [icked up my hoodie. Or dad's hoodie, I kinda stole it from him when I was younger but he doesn't seem to mind. After I get my hoodie on I pick up my scarf and wrapped it loosely around my neck and letting the five ends tail down my back. Once I had finished I waslked over to my couch that was a dark teal color and plopped down grabbing the remote and turned it on flipping through the channels relaxing.

*Nightmare's prov*

I teleported to my room after sparring with Luna. he's gotten stronger I'll give him that. If I would have used my full strength he wouldn't have been able to get close to me. I sighed resting my skull on my hand "maybe I've gone a bit soft" I look at the picture I had taken of Luna when he was a babybones and smiled. I shook my head and growled rubbing my skull.

'Well.... Is there a AU that I still need to take over that will be good for Luna's first time? Hm?... but also with Luna's help, my pathetic brother and his friends don't know about Luna so I can use that to my advantage' I chuckled darkly smirking "thats perfect"

*no ones prov. Stil with Nightmare (sorry forso many prov switches!!)*

Nightmare contineud to think of the plan he was going to have Luna help with along with which AU to bring Luna to first. Nightmare smirked as he couldn't wait to show and teach Luna more on what he does and how to be a true prince of darkness.

Nightmare called Blackberry and Horror to the throne room as he teleported there and sat in his throne. His tendrils flailed around him fiercely as he smirked. The two skeletons came into the throne room shortly after Nightmare as Nightmare started to explain to them what they'll be doing durring their next outing. Once NIghtmare was done explaining. He called for his son Luna.

It didn't take Luna long to get to the throne room as he teleported. "Ready to take over your first AU son?" Nightmare asked his smirk never seeming to faulter "Yes Father" Luna replied and smirked back at Nigthmare as Nightmare started to explain what they'll be doing and where they'll be going.
