A/N: SURPRISE IM BACK
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My body shook with power, I haven't felt this much adrenaline in so long, not since my first killing. Killing, yes, that was exactly what I planned to do to this damn puppet.

"Let's see here, what to do, what to do, so many possibilities and with frozen time, well, I have all the time in the world to put you something worse than Hell itself!" I could feel Nightmare's amusement at my taunting. Pent-up rage mixed with bloodthirst is dangerous. Lucky for Nightmarionne, although really unlucky, it was the perfect target to release it all.

Nightmarionne's hiss came out with frustration and a hint of panic, "No matter, you're only half a nightmare with the powers of an heir, you'll tear yourself apart before you can even control it. I will watch you rip your weak flesh with joy!" Nightmarionne sent out more red arrows connected with strings.

I moved my legs, standing to the side as the arrows whipped past me with a small whistle. My belly mouth took this as an opportunity to clench its sharp jaws on the red strings that connected to Nightmarionne.

Taking those strings into my claws I used my boosted strength and pulled, letting out a playful laugh as the puppet tried to pull its strings back, "Come on, Nightmarionne, why don't I give you a swing!" I pulled its body, spinning my body along with Nightmarionne.

I could feel it getting frustrated as it made an attempt to cut its strings, "Enough of these games, child!" I hummed and abruptly stopped, "You're right." Smirking, I clenched the strings and swung my body to the side, "Let me put you down!" I slammed Nightmarionne's body to the ground, creating a large crack where it landed.

I shook my claws off with a whistle and turned my body away from Nightmarionne, "Damn, I'm good."

I felt a few things stab into my belly and chest and looked to see a few of Nightmarionne's arrows impaled into my body.

I slowly turned and saw Nightmarionne breathing heavily and glaring at me. A smile of triumph plastered on its masked face. I'm surprised how fast the puppet weakened.

For someone who put me through hell and practically almost killed Nightmare, it was easy to throw Nightmarionne off. A sudden question almost made me smile.

When was the last time Nightmarionne trapped and ate a child?

But I can't have it see me smiling, I needed to pretend to be down. So I coughed and with the help of Nightmare, made myself cough up black ooze.

Nightmarionne laughed and started to forcibly pull me towards it, "What did I tell you, stupid child, you can't handle the power. You got cocky, and now I will enjoy devouring both you and Nightmare's life!" It pulled me until I was right in front of the puppet. I let my body wobble and sway, lowering my head in what seemed like defeat.

"Any last words, (Y/N)?"

I held my head up, "Yeah..." I grasped Nightmarionne's head, letting my claws dig right into its animatronic skull. Nightmarionne's eyes widened when it saw my lips curl into a sinister smile.

"Bon appétit."

My mouth started to crack widen, letting my jaws unhinge. Nightmarionne tried to struggle from my grasp, but my belly mouth decided to take a bite of the puppet's torso.

"No! You can't defeat me! I am Nightmarionne! I am an heir!"

Nightmarionne shouted in protest, but my hunger needed to be satisfied. I grew larger, letting myself practically swallow Nightmarionne whole. I heard a snap, and knew that my belly mouth had taken half of Nightmarionne, splitting the puppet in half. Its screams quieted as I felt myself finish it off.

I felt pressure against my chest and gave it a few hard hits with a fist. I let out a loud belch and instantly covered my mouth, "Oh hell, that was so bitter." I felt Nightmare shake his head and I shrugged, "What? Have you tasted this guy?" Note to self, evil beasts taste like the bottomless pit of black coffee.

I wanted to take in the fact that I finally won against Nightmarionne, but a couple thoughts came to mind. I still had a few couple seconds left to make a decision.

With a wave of my hand, two doors appeared, the same gold and white one, and the black and red door. Walking towards the Nightmare Realm door. I felt my belly mouth start hacking and coughing. I looked down with a frown and disgustedly scrunched my face, "Out with it belly boy, you're making me gag over here!" Out was the key Nightmare gave me. It clattered on the floor, covered in what looked like blood and mucus.

"What the fu-?" Nightmare aggressively grumbled. "Right, right, sorry, language, hey wait," I again scrunched my face up, "Ew, if you're like, a part of me, does that mean you'll see me and Plushtrap..." I could feel Nightmare's whispers in my head, they weren't exactly words, it just sounded like a bunch of childish creepy whispers but I understood what he said.

Nightmare can close himself off whenever he liked, giving my body and mind full control. It would seem like he was never there. It would be obvious physically as the third eye on my head would be closed, indicating that Nightmare was "sleeping". Really he'd only appear if I absolutely needed him.

So I can have my sexy time with Plushtrap without worrying about Nightmare. Quite a blessing really.

I walked and knelt down to pick up the key, gagging as I used the fabric of my outfit to wipe off the blood and mucus, "That's so disgusting, remind me to never use my belly mouth for storage. I never know how you and Uncle Fazbear keep every object you have clean." I perked up, "Uncle! I forgot about him! Crap, I lost him when I was against Mangle!"

Nightmare whispered that he had found Uncle Fazbear before coming to my aid when he finally figured out how to break through Nightmarionne's dimension shields. He had help from Auntie Fibi, who should be resting. She was able to crack the shields enough for Nightmare to break through and it took a toll on her energy. I was relieved that everyone had been safe. 

Speaking of Mangle, the corner of my lips lowered at the thought of seeing her suffering the way she did. I had to find her, I had to bring her back, she deserved a second chance dammit!

I could feel Nightmare reassuring me that Mangle could be brought back if I can just find her plush somewhere in the Mortal Realm. It might take a while now that she's hollow and we won't sense her nightmare energy source, but I promised her a better life.

I walked to the red and black door and held the key to the keyhole, "Okay, let's get back ho-"

"Can you hear me?"

I froze, the key was in the keyhole, but I stopped before I could turn and unlock the door.

I knew that voice.

"I don't know if you can hear me."

Nightmare tried to ask what I was hearing, but I kept looking around in the realm. There was no way I could hear him.

"....I'm sorry."

Luke?
