The Equestrian Maelstrom

Nightmare Moon was laughing at her victory before see a three pronged kunai aimed at her. She dodged it and laughed at the attempt.

"You missed!"

"Did I?" A male voice called behind her.

Her eyes widen and turned, seeing Naruto there and she sees traces of red particles and that is when it hit her. The kunai wasn't meant to hit her but it acted like a beacon to allow this fox to teleport right next to her, like teleporting from Point A to Point B.

'Clever.' Nightmare Moon thought with an impressive look from behind her shocked expression.

Naruto punched the moon alicorn and sent her flying backwards. Nightmare managed to stop herself and summoned a sword to her side and entered a fencing fighting style and Nightmare Moon smirked. However, what happened next shocked her more. Naruto pulled out his sword and entered into the same stance, surprising everyone but Rainbow, Applejack, Pinkie Pie, Fluttershy, and Rarity.

"Y-You're a member of the Night Guard!?" Nightmare Moon said, shocked.

Naruto smirked "I learned from the Guard Academy and trained on all the fighting styles in every Guard Corps; including the mysterious Night Guard." Naruto's expression changed to respect "I learned and memorized not just the fighting styles to mastery but learned of their history. And I knew all about you long before you returned and I have to say this."

"What?" Nightmare Moon asked, unsure.

Naruto did a bow, surprising everyone "It is an honor to face the very creator of this fighting style in person and an even greater honor to actually duel you." He returned to his stance with a smirk "Though, don't think for a second that I'll let you have an advantage. Remember; I learned all the fighting styles of every Guard Corps, making me have an advantage to counter against your only fighting style."

Nightmare smirked "Alright, give me a show to remember you by."

Naruto nodded and the two disappeared in a flash of teal.

The two appeared on a platform, high above the sky and just out of sight. The two stand firm before charging. When they were very close, Nightmare swung her sword and Naruto blocked the sword. Nightmare Moon pulled back and took to the skies and summoned multiple swords and fired them at Naruto. Naruto looked at the incoming blades before chains with spikes came from his back and stomach.

"Magic Chains: Shield Formation!" Naruto shouted as the chains formed into a shield and blocked the attack with ease. Naruto immediately felt Nightmare behind him and was charging fast. Just when Nightmare was about to hit Naruto, more chains came out of his back and charged right at her.

Nightmare immediately stopped and flew back as Naruto turned his gaze to her before all the chains returned to his body and he aimed a hand at Nightmare Moon.

"Universal Pull!" Naruto shouted.

Immediately, Nightmare Moon was being pulled to Naruto's hand against a powerful force. Once she was close, she tried to cut at him only to see Naruto's sword blocking the attack and Nightmare sees she was in front of Naruto and that is when she sees Naruto's rinnegan left eye.

"Almighty Push!" Naruto shouted when she was in front of him.

Nightmare felt herself pushed and saw that he had pushed her towards the surface. She crashed into a bunch of trees from the Everfree Forest. When Nightmare stopped, she saw that she was scratched and bruised and some of her armor was broken off. She was about to after him when she sees the wood around her beginning to grab and pin her down.

"Wood Style: Deep Forest Bloom!" Naruto shouted as the wood began to cover Nightmare Moon. Naruto was about to sigh until he sees smoke leave the wood and he knew she entered her smoke form to escape the jutsu. Nightmare Moon reformed to her normal form in mid-air.

Nightmare had to admit, Naruto was putting up a big fight. She thought this battle was going to be a bit dull but this… this far surpass what she thought of the fox. She grinned and fired a teal laser beam at Naruto but he dodged and threw a bunch of shuriken at Nightmare Moon. She dodged and was about to attack again but that is when she heard 'POOF' and looked, seeing that 5 of 8 shurikens turned to Narutos, making Nightmare's eyes widen in fear.

The clones landed on the tree and charged at Nightmare Moon. Nightmare summoned forth a giant scythe and cut the clones down, making them poof again. She turned to Naruto, only to see him gone.

'Where did he go?' Nightmare thought, looking around before she put her weapons away 'Why fight me then suddenly turn to retreat. He's no coward, but it was almost like...' Her eyes widen in realization 'He distracted me not with clones but kept my attention away from something! He must have pulled back when he achieved something! But what could he use against me~'

Nightmare Moon's gasped in realization before turning towards a ruined castle in the Everfree Forest "The Elements! He's after the Elements!" She began to fly to the castle.

"You do know it'll be a matter of time before she realizes that you stalled enough time for Twilight and the girls to get to the Elements."

"I know but by the time she realizes, it'll be too late." Naruto replied to Kurame. He knew well enough of Celestia's plan. He knew Twilight, Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie Pie were the Bearers of the Elements. However, Naruto had a backup plan should the plan fail.

Naruto arrived when the girls made it to the Castle entrance. They heard his arrival and looked, seeing Naruto land in front of them.

"Naruto!" The girls shouted and hugged me.

Naruto smiled before his face turned serious "I hope you girls have a good reason to be out here."

Twilight nodded "Yes, we are going to use the Elements of Harmony."

"Will they work?"

"Nightmare Moon was defeated by the Elements before, it should work again." Twilight said.

Naruto smiled "Well, I guess it is worth a shot."

They went inside and both Fluttershy and Rainbow brought the elements down to them. Naruto kept an eye out while the girls, aside from Twilight, left to go outside. When Twilight ignited her horn, she reached a hand out to the elements until a small tornado began to swirl in the middle of the elements, sucking them up. Twilight cried out in shock and jumped into the tornado with Naruto following behind.

Naruto groaned and opened his eyes, seeing himself right next to Twilight and across the room, he sees Nightmare Moon with the stones of the elements. Naruto noticed that around him, everything was shadowy.

"Twilight, are you alright?" Naruto asked, but Twilight didn't respond and was looking around.

"Naruto, where are you?" Twilight asked.

"I'm in front of you, Sparkly." Naruto said before his hand went right through Twilight's chest.

"It's useless, she can't hear or see you." He heard Nightmare say.

He looked and saw a Nightmare Moon next to another Nightmare Moon. However, the Nightmare Moon on the right (the newly appeared) was looking at Naruto while the other one was focus on Twilight.

"Like the environment around us? It's my personal realm, the shadow realm. Here, we exist outside the boundaries of the real world. We cannot be seen, heard, or anything in the real world. I was able to go to places in secret and in this realm." Nightmare Moon said with a smirk "However, me and Luna got sealed inside the moon. But for being in there for 1000 years, me and Luna felt the same thing together and soon, we became part of each other but we had to split off in halves. Luna had everything a normal pony had, while I..."

Nightmare grinned lustfully and snapped her fingers and black tentacles came from the ground and wrapped around Naruto's legs, arms, and forced him to the ground. Naruto looked up from the ground and immediately blush from the sight he saw.

Nightmare Moon (Moony for Naruto) was no longer wearing armor. She wore a blue bikini and panties with armor boots still on. Now that Naruto looked at her, she was more beautiful than what the stories and pictures shown. Then again, Celestia had admitted to Naruto that since they were alicorns and Princesses, they couldn't have love relations to other ponies due to mortality, which is actually reasonable. Many wouldn't have love relationships if something like that or other things would bother the relationship.

"Like what you see, foxy?" Moony said with a lustful grin, enjoying the blushing face of Naruto "You see, alicorns can't have relationships or sex slaves so they keep their virginity. However, they can get rid of these sexual urges by reincarnating them as other ponies and put them somewhere secret. And I, Nightmare Moon, am Luna's sexual reincarnation."

Naruto immediately knew what Moony wanted now. For 1000 years, being stuck on the moon, it had to be very stressful to not get rid of the sexual stress and Naruto knew that Moony was going to make Naruto her first.

"Wait," Naruto said, a thought occurring to him "you are Luna's sexual reincarnation and princesses can't enter sexual relationships, right?" Moon nodded "Then where is Celestia's reincarnation?"

Moon was about to resort before she stop, thinking about it. Moony's eyes widen in shock.

"I... I never took in account of her." Moon truthfully as she began to think about the other possible Tia somewhere in Canterlot.

What she didn't noticed was that Naruto was trying to stall for time for Twilight and the others to use the elements on Nightmare Moon. He needed to make sure that Moony doesn't try to interfere. After what was five minutes, Moony was thinking about the sexual incarnation of Celestia before she smirked.

"I can deal with her and seal her away inside the Moon, like I did with Celestia." Moony said before she noticed Twilight and the girls about to fire the Elements "NO!" She glared at Naruto and her armor returned "You tricked me!"

In the real world, the Rainbow that was fired from the elements hit Nightmare Moon while she cried out in fear and she was surrounded by a mini rainbow tornado. Then there was a flash of white and when it went down, the Mane 6 were on the ground and they began to get up. They were commenting about their necklaces and Twilight's crown before they see Celestia arriving. Then they see Princess Luna and she was welcomed to Equestria once more. They were about to leave when Twilight stopped them.

"Wait!" Twilight shouted and began to look around the room "Where is Naruto?"

"Over here!" They heard a shout nearby and began to run after where the source was. They arrived what was Luna's old room and sees Naruto was chained in the center of the room and they see Nightmare Moon on the bed, knocked out.

"What happened Naruto and why is Nightmare Moon on the bed?" Celestia said as she unlocked Naruto from the chains.

"Well, how about you tell me Tia." Naruto said as he stretched "You never mentioned to me about you princesses could reincarnate your lust and desires into a different persona and pony."

"You mean..." Celestia's eyes were widen at what Nightmare Moon was truly.

Naruto nods "Yes, Nightmare Moon is really Princess Luna's reincarnation of sexual desire." That made everyone gasp in shock and surprise at the revelation "The Elements separated Luna and Moon and brought both of us here. To be honest, she was going to rape me and tried to seduce me to embrace the darkness. But when the elements hit Nightmare Moon, Moon lost her affiliation towards the darkness and has returned to her normal self."

Naruto looks at Celestia "Speaking of reincarnations... Where is your reincarnation, Tia?"

"Well..." Celestia said before sighing "Return to Canterlot with me after the party in Ponyville, I'll explain more there."

Naruto nods before adding to no one "Before you even consider it, I won't enter a relationship without knowing the pony first, Moony."

"You're no fun, Foxy!" Everyone heard Moon reply and looked, seeing her get up. She now had a blue top with black shorts and wore royal shoes with the necklace and crown "And how did you know I woke up moments ago?"

"I have my ways." Naruto stated before he smirked "Though, I don't mind you visiting every now and then."

Moon smiled deviously "Oh, trust me, I will be visiting in more ways than one."

Naruto nodded and they all became to walk back to Ponyville.
