Everyone went outside and saw all the chaos Nightmare Moon had been causing. The skies were swirling vortexes up high summoning ponies in nightmare form. Most of the buildings were destroyed, everyone was screaming in fear, and purple fire was burning the ground up. Some of the nightmare ponies were possessing others forcing them to kill the members of their families. Needless to say it was pure terrifying.

"Hot damn!! This Nightmare Moon witch ain't kidding around here!" Demon said.

"She must have been busy. We gotta stop her and save Cadence!" Twilight said.

"Im coming too! She's my marefriend and I won't let her get tortured by Nightmare Moon!" Shining said.

"Well Shining. Im glad you are. Now let's go find that wicked witch!!" Demon said summoning his wings and flying to the castle while the others followed behind.

Our heroes arrived at the castle of the two sisters. It was rebuilt into something that even would outdo Dracula's castle in Transylvania. There was banners of a skull covered in stars representing her logo, the walls were painted a midnight blue, the towers have been remodeled into defense towers with cannons that can shoot blue firework cannonballs, and there were guards in nightmare armor all around. Our heroes needed a plan to get inside and fast. Cadence wasn't gonna survive in there for any longer.

"Nightmare Moon was busy with the repairs on the castle. She's got guards all over the place." Twilight said.

"Oh I hate to think of Cadence in there. We got to get her out!" Fluttershy said crying.

"Don't cry darling. We'll get her out I promise you. We just need a plan to get inside the castle." Rarity said.

"So Demon. Do you have a plan to break in?" Shining said.

"Well I do have one plan. Shining you and the others need to distract the guards long enough for me to sneak inside the castle and find Cadence. When I find her i'll give you the signal by shooting some red lightning in the sky. When you see it you guys jump in and blast any guard in your way and keeping going til you find me. Got it?" Demon said.

"Got it. But how will we distract the guards?" Shining said.

"Yeah and where's Pinkie?" Twilight said.

"Um does that answer your question?" Demon said pointing at Pinkie with her party cannon heading to the guards.

"Yeah that does. Alright Demon we'll distract them. Get in there and find Cadence." Twilight said.

"And Demon. Don't stop til Nightmare Moon is done for." Rainbow said running with her friends to distract the guards.

"Oh she won't know what hit her. Cadence never fear! The Demon King will be there!" Demon said summoning his wings and flew into the castle while the ponies were fighting them.

Inside the castle Demon went into ninja mode and quietly snuck around to see where Nightmare Moon was keeping Cadence. He searched high and low seeing all the windows with many nightmares to scare anyone, but it's doesn't seem to scare Demon. He heard some guards marching coming his way and hid behind one of the pillars. The guards passed and Demon came out of his hiding place.

"Whew. That was a close call." Demon said as continued looking around for Cadence.

He continued for 3 hours til he reached the throne room. He figured if there was anyplace that Cadence could be it's there. He quietly opened the door and snuck in closing it softly so it wouldn't draw too much attention. Demon saw the throne room was all scary looking and to his surprise he saw Cadence. She was chained up and wearing a starry slave outfit. Cadence saw Demon and smiled.

"Demon? Is that you?" Cadence said.

"Yes Cadence. Now don't worry. Im gonna get you out of here. Lemme call the others." Demon said as he summoned some red lightning signaling the others that he found her. The ponies saw that and went straight to the source.

"Now lemme get you out of those chains." Demon said.

"Oh I dont think so." A voice said.

Demon saw some purple mist coming into view and started forming into a black vampire like ailcorn. She was without a doubt the demonic ego of Luna: Nightmare Moon.

"Nightmare Moon. I should have known you were coming to stop us." Demon said.

"Yes. And im surprised that you were able to sneak inside my castle without my guards noticing you." Nightmare Moon said.

"Well don't flatterer yourself." Demon said.

"Oh I saw you signaling your pony friends to stop me. Im afraid I can't have that." Nightmare Moon said using her magic to shut the doors before Twilight and her friends could get in.

"Now your in here all by yourself. How will you ever get out of this?" Nightmare Moon said but Demon smirked.

"You think im scared of you? Bitch please I do the scary stuff around here. Now hear this. Let Cadence go or i'll give you something to be REALLY scared about." Demon said.

"Ha! You must be a real fool. Do you really think you can stop the most powerful being in all of Equestria?" Nightmare Moon said.

"Moonbutt you have no idea who you're dealing with. Luna had her demons in the past. But now that you're out and all by your lonesome you'll now find out.....that I got my demons too." Demon said.

The symbol glowed on your chest and your eyes glowed a hellish red and began the transformation. Your skin is a sickly white, demonic writing appeared on your shoulders, the muscles flexed a little, demon tail and wings appeared on your back, your teeth sharpen, horns grew on your head, and finally claws grew on your hands and feet. The transformation was complete and you stared at Nightmare Moon ready to fight. Nightmare Moon was surprised.

"Well. That's something. You know what? We dont have to fight. Lemme offer you a deal. You and me together. We will rule Equestria and be king and queen." Nightmare Moon said.

"Your kidding right? I would never agree to that. I already have a place as king. Now come at me and suffer in hell!!!" The Demon King said shooting red lightning as Nightmare Moon and dodged.

"So be it then. You will know you're place where you belong!!" Nightmare Moon said.

The both charged into battle and began to fight. The two threw some punches at each other, then flew into the sky and went punching again. This lasted for 15 minutes til The Demon King injured both of Nightmare Moon's wing by squeezing them real hard and breaking the bones in them causing her to scream in pain. He threw her down to the ground and she crashed hard. He conjured some red lightning and zapped her as she screamed in agony. He flew down and landed in front of her.

"HAHAHAHAHA!! How low you fallen Moonbutt! Now I wonder something. What exactly is the dark princess scared of?" The Demon King said.

Nightmare Moon got up. "Me? Scared? What a joke! It should be you that's scared!" Nightmare Moon said blasting her magic at him. But he remained unfazed.

"What?" Nightmare Moon said trying again but got the same result.

"How can this be?! No one's ever immune to my magic before!" Nightmare Moon said.

"Yeah your facing a demon king bitch. Now lemme show you some dark magic you'll never counter!!"The Demon King said.

He conjured more red lightning and zapped Nightmare Moon again. She screamed in agony and fell in pain. She looked at the Demon King and for the first time cowered in fear.

"Aww would you look at that. The dark princess is actually feeling scared. Now that's something you don't see every day." The Demon King said.

"Ok that hurt a little bit. But even so you won't stop me from covering the land in eternal night!" Nightmare Moon said.

"Oh please. You gotta be dumber than I thought. Eternal night? Pathetic." The Demon King said.

"You dare mock me?!" Nightmare Moon said blasting her magic at him. But he grabbed it and tossed the red lightning ball at her. She got shocked and fell to the ground.

"Wow. Trying to blast me a third time? You never learn do you? Now let's see what nightmares you will have for years." The Demon King said flashing his eyes turning her castle into the nightmare realm. She looked around and seeing all sorts of demonic nightmares. Then she heard the footsteps of the giant demon king coming towards her.

"HERE I COME MOONBUTT!! HAHAHAHAHA!!!" The Demon King said.

She screamed and ran as fast as she could. But no matter how fast she went she couldn't lose The Demon King. He conjured some red lightning and breathing red fire balls at Nightmare Moon. He got a few on lucky hits on her but she still kept running. 4 hours passed and her legs were aching bad. Suddenly she ran into a wall breaking her face and bringing her back to the real world. She fell down in exhaustion.

"Ok. Your pretty good." Nightmare Moon said trying to get up. "But even with your demonic strength I won't be defeated by the likes of you!!" Nightmare Moon said.

"Really now? Cause with the state your in I would say otherwise. Now this wouldn't be fun if I didn't bring some friends to the party. Let's bring them here shall we?" The Demon King said.

He summon a portal and out came thousands of demons all growling at Nightmare Moon. She was now even more scared.

"A demon army?! Just how powerful are you?!" Nightmare Moon said.

"Uh hello? Im The Demon King Moonbutt. You wanted to vanquish the day? Not today. Now you're gonna pay. Scary demons of the night attack Nightmare Moon and win the fight!!!" The Demon King said.

The demons obeyed his command and charged at Nightmare Moon. They all jumped at Nightmare Moon and attacked her. She tried to use her magic but the demons outnumbered her. The demons breathed fire, bite bits of her skin right off, use lightning attacks of their own, and use their claws to make her bleed. She screamed in pain and after 50 minutes the demons stopped and returned to the underworld. Nightmare Moon struggled to get up but The Demon King grabbed her by the throat.

"Oh no you don't!! You ain't going nowhere Moonbutt!! I told you that you can't stop The Demon King! And now your gonna pay! This is the end Moonbutt!!" The Demon King said dropping Nightmare Moon.

He summoned a demon head and blasted dark magic at Nightmare Moon shocking her real bad. She screamed with every blast she took. One blast hit her in the face and she fell down out cold. The Demon King flew up and prepared a giant ball of red fire. Nightmare Moon who just covered was still weak to use magic but saw what the Demon King was doing.

"No!! You can't possibly stop me this easily!! You can't do this!!" Nightmare Moon said scared.

"HAHAHAHAHA!!! SO LONG MOONBUTT!!" The Demon King said.

He threw the giant ball of red fire at Nightmare Moon and when she saw it she freaked out knowing her time has come.

"NOOOO!!!" Nightmare Moon screamed.

The fire balls hit Nightmare Moon burning her skin off. She screamed in pain as her flesh was starting to melt off her face. It continued til she was nothing but a pile of boiled blood and bones. Then the skull of Nightmare Moon that was laying there was crushed by the Demon King's foot. Finally he unleashed a demonic roar knowing he was victorious. The transformation was undone and you returned to normal. Then you went to Cadence and got her out of those chains. She wrapped her arms around you crying happy tears. You returned the hug as you tried to calm Cadence down.

"Oh thank you Demon for saving me! I wasn't sure how longer I could be in here." Cadence said.

"Well it won't be any longer now." Demon said.

Suddenly they saw the castle starting to crumble down. Demon got out his wings and grabbed Cadence and took to the skies escaping the castle. Twilight and her friends saw the castle crumbling and Shining led them out of here before they all got crushed.

<>

Our heroes escaped the crumbling castle as they watched it come to the ground. Then the vortexes in the sky vanished and the night returned to normal. Nightmare Moon was defeated but our heroes lowered their heads in sadness thinking that Demon and Cadence didn't get out in time. Even Shining cried a few tears. His mare and soon to be wife was long gone.

"Cadence. She's gone. I dont know what to do now." Shining said.

"We should have broke the door down so we could have helped Demon stop Nightmare Moon." Applejack said.

"Yeah. Now he's gone too. I never got to tell Demon how I feel about him." Rainbow said.

"Rainbow. You actually love him?" Fluttershy said.

"Yes Fluttershy. The minute he came here I felt a connection towards him. But he's gone. I never thought that the Demon King could been defeated." Rainbow said crying.

"Should have saved them when we had the chance." Rarity said.

Then suddenly they saw two beings coming down which brought smiles to everyone's face: Demon and Cadence! They landed and Demon gently put Cadence down.

"Demon! Cadence!" Everyone said as Shining ran and hugged Cadence while Rainbow hugged Demon.

"Im so glad to see you!! I thought you were done for in there!" Shining said.

"I would have been. If it wasn't for Demon stopping Nightmare Moon." Cadence said.

Shining went to you and looked you in the eye.

"Demon. You really showed us that even a human with demonic powers can be a hero. Thank you so much for saving Cadence from Nightmare Moon. As a reward you will be the guest of honor at my wedding in 2 months." Shining said.

"Thanks Shining. That means a lot. And I knew you be devastated if I didn't save her. So im glad that you two will be getting married for real." Demon said.

"Me too. Again thank you for saving her." Shining said.

He hugged Demon and went back to Cadence. Rainbow went to Demon next knowing it was time to confess her feelings for him.

"Demon. There's something I really wanted to tell you. From the day you came to Equestria I felt a connection between us. The way you turned into the Demon King and fight any evil really made me feel safe. What im trying to say is....I love you Demon." Rainbow said.

"Wow. You know Rainbow there's something you should know too. I kept having those dreams about you every night. I couldn't stop thinking about you since we met. So I feel the same way." Demon said.

Rainbow started to cry happy tears from hearing those words.

"Does this mean you'll be?" Rainbow said.

"Yes. I would love to be your boyfriend. Now come here you!" Demon said opening his arms.

Rainbow ran to him as he caught her in his arms twirling her around. He then put her down and shared a passionate kiss. It lasted for 5 minutes and they separated. Cadence smiled seeing the two so happy together.

"I knew you be able to confess to Rainbow about your feelings. I say from here on out you are part of our family. You'll never be alone again." Cadence said.

"Thanks Cadence. Now I know why you are called the Princess of Love. I couldn't have done it without you." Demon smiled.

"Your welcome. And here's a little something for saving me." Cadence said kissing him on the cheek. After that she went off to catch up with the others leaving Demon and Rainbow alone.

"Im glad you stopped Nightmare Moon. Now she won't be causing anymore problems." Rainbow said hugging him.

"Me too Rainbow. No evil can get passed The Demon King. Let's head home Rainbows." Demon said.

"Yes my king. And went we get home I have a special treat for you in the dream realm. You're gonna love it." Rainbow said.

"I bet I will Rainbow. Now let's head home." Demon said.

The two headed off leaving the forest. The Demon King defeated Nightmare Moon and saved Equestria once more. Now all that's left is the wedding. But after they left something or somebody was watching Demon.
