Before we beginning of the story, here is what is going to happen. As this is a crossover between Naruto, My Little Pony, and Overlord; there is going to be more than just that. The main character is going to be Naruto Uzumaki-Namikaze and he is going to be the first Overlord in Equus. So let me get some facts straight before the story begins.

For the start, like the other Maelstrom stories, both Equus and Elemental Nations are combined with the people of EN being anthro ponies like the Equus species. Chakra is replaces as a unique form of magic, it is referred as Elemental Magic. Demonic Chakra is similar, it is referred as Demonic Magic. For Naruto, it'll be explained later in this.

For the My Little Pony Universe, all the species there are anthro so they will be wearing clothing on them. I am also adding Rule 63 for some characters, most will have a twin or relative (like a little/big sibling or a clone of original) of that character. I am also including the two characters of Princess Trixie Sparkle; Astelle and Shadow. I may add some other stuff from Princess Trixie Sparkle.

For the Overlord Universe, Gnarl and the minions will be present. The tower will be The Netherworld Tower (since Naruto was banished to the darkest and deepest part of Tartarus). For spells, they will be the Fire, Domination, Minion, Shield, Lightning Whip, Evil Presence/Target, and Halo. The Minions are the same (the same Browns, Reds, Greens, and Blues). The armors and other stuff are still there.

As for Naruto, he is still his anthro kitsune self (though he is now dark) and instead of shinigami and kami sending him to Equestria, it was Yami (Goddess of Darkness). Naruto becomes the first Overlord in Equus, he is also genius and powerful due to him merging with Kyuubi and becoming a Demon Lord (*cough* Spoilers *cough*).

Now for the major stuff, there will be a harem. I'll let you guys (the viewers/readers) think of who should be in the harem, on the condition that only villains and people that can be corrupt can be voted but pure goods like Celestia can't be picked, but that means people like Daybreaker can be picked or even Twilight Sparkle (if she gets corrupted by Dark Magic) can be picked. I'm also adding a darker type of Changelings known as Darklings and some other darker species like Vamponies, Lamia, Arachne, and more into the story. I will be adding other species like Caribous, Monkeys, and some other species. There will be more stuff on the way but for now, live with it. However, I am going to replace what Netherghuls are going to be. Instead of being candidates for being the next Overlord, they will become something similar to Four Horsemen of World of WarCraft, they will be the Champions (Generals) of the Overlord, their purpose is to lead Minions into war and fulfill tasks given to them by the Overlord.

Now no more delay, the beginning will be familiar for those who read "The View of Other Maelstroms".

There was an anthro alicorn flying through the sky. She had very dark blue, almost black, fur and had blood red mane and tail. Around her neck was a piece of line string that was attached to the Alicorn Amulet. She wears a black cloak around her and she lands on the ground. Then, a flash of orange next to her and an anthro nine tail fox appeared next to her.

The nine tailed wears a red shirt with a black cloak, black cargo pants, black sandals, and has nine tails. He had orange fur and electric blue eyes.

The two stared at the front door into the palace. Around them was nothing, no pony in sight. The alicorn was frowning in disappointment. That is when the front doors opened and out stepped an old, ancient looking, unicorn with a long white beard and white mane and tail and wore robes. He had blue fur.

"No adoring crowds or grand entrances to welcome your queen?" The alicorn asked to the bearded pony "You must have told many slanderous lies about me to have the ponies flee in my presence."

"Astelle, my pupil, what has become of you?" The bearded unicorn asked to the alicorn before looking at the fox "And who is that?"

"Oh, this?" Astelle opened her wings to look at herself before looking at the unicorn "Don't you find this a good look on me? Seems your elemental magic isn't all cracked up to be, now is it?" Astelle questioned the unicorn before folding her wings again "You withheld how powerful this new magic can be. Powerful enough to beat the great Starswirl." She narrowed her eyes at him dangerously.

"And my name is Naruto, Naruto Uzumaki. I am Astelle's friend and partner." The Nine Tailed Fox answered.

Starswirl began to step forward "Magic based in darkness can only corrupt. You can never truly be happy if you embrace it."

Starswirl noticed the magic attack from Astelle and blocked it.

"How DARE you speak to be about happiness!" Astelle shouted to him "You destroyed MY happiness a long time ago!"

"I am sorry for the pain I cause upon you, Astelle." Starswirl apologized "My miscalculations have come to a great cost to you. But seeking revenge will not appease your anger. It can only serve to fuel it."

Astelle growled at Starswirl "Oh, you're 'sorry' are you? You're 'sorry' that you destroyed my life!? And kept secrets from me, knowing what it would do it me!? I demand that you take back your curse from me or I will show you no mercy!"

"It is unwise to venture down this path." Starswirl warned Astelle "There is no need to destroy what little sanity resides within you with violence."

"You are the reason for everything I am!" Astelle shouted at Starswirl "You could have followed after me and try to see reason. You could have had it all, Starswirl, but your pride outweigh your good judgement!"

"Worry not, old fool." Naruto continued with a frown "The tears that Astelle once shed are long gone. And her better judgement showed just how blinded she truly was to you."

"In fact, you should rejoice." Astelle continued with a dark tone "For I have come to give you exactly what you wanted from me all along: permanent release. When you are out of my way, there will be nothing left to stop me from curing the plague you have placed on these ponies."

"I can't allow you to do that, Astelle." A female voice said from behind the door of where Starswirl stood.

Astelle and Naruto looked at the source of the voice and Astelle was shocked and surprise to see who it was.

"Celestia?" Astelle asked to her.

"You have to let this go." Celestia said to her in a begging-like tone "Starswirl's right. There is no good that can come from this."

Instead of understand, Astelle became very angry and looked at Starswirl with rage "How dare you inflict this pain and responsibility upon my sister! You have corrupted EVERYTHING I hold dear and I will take great pleasure in destroying you!"

Celestia began to speak in a begging tone "Astelle, please… Don't do this! I don't want to fight you!"

Astelle looked at her "Stay out of this Tia. You can't understand the damage he's done to me, to you, to ALL of ponykind! I am this world's last hope for redemption."

"I am sorry it has come to this, but I can't allow Equestria for your misguided vengeance." Starswirl said to him.

Naruto growled and he cloaked himself in an orange aura "What would YOU know, old fool? I was supposed to be my village's hero and look what THEY did to me! I am abused, tortured, and more! I follow Astelle because she is the only one who has EVER showed me kindness!"

"Missguided?" Astelle laughed at what Starswirl said "You know NOTHING, you old fool. Did you really think you could mold me into become your puppet!? Telling me all these lies about my destiny and my fate! Without once even considering what I want! Or even what is even good for Equestria! You put up a good disguise of wisdom and power but I know the truth! I know what you really are! A coward!"

{Play song: "A New Era Begins" from Magpiepony.}

Continue after the song ends.

Celestia was crying against the Tree of Harmony that Starswirl was turned into. Astelle was giggling darkly before laughing evilly at the fate of Starswirl. Naruto, who was leaning against the stone wall, was grinning at the misfortune of Starswirl.

"Such a perfect ending for the mighty 'Starswirl the Bearded'!" She looked at the Tree of Harmony "Forever trapped in the form of a tree, unable to find the sweet release from immortality that he so longed for." She looked above the tree and see five gems "And better yet, I found exactly what I have been looking for: The Elements of Harmony!"

Celestia turned to Astelle, tears still crying from her eyes "I-I won't let you do this, Astelle! Whatever evil plan you have stops now!"

"You don't know what you're talking about Celestia. I'm only going to make the world a better place." Astelle told her. "Ushering that new era of peace and prosperity. And banish the CURSE on our linage."

"Yeah Celestia." Naruto agreed "A world without magic is a perfect world. Magic is the cause of our pain, what better way to end it by destroying the source?"

"Ushered in by your hatred and destruction!" Celestia accused Astelle "The only curse I see on our linage is YOU!"

Celestia surrounded Astelle with her golden magic.

"Astelle!" Naruto called out and looked at Celestia. Naruto charged at Celestia but she pushed him back against the wall.

"For the future of Equestria. I, PRINCESS CELESTIA, banish you!" Celestia shouted in the Royal Canterlot voice. "Never again will your treachery harm anypony here or here after!"

"NO!" Naruto shouted and attempted to charge but Celestia pushed him back into the wall, more force into it this time.

"W-What?" Astelle asked to Celestia in shock "B-But I did this for you, for us. You have to let me explain, Tia! Tia, don't do this! Tia, you're my family, please!" Astelle began to be sealed into a painting "Tia!"

"NOOOOOO!" Naruto shouted as he got out of the rock.

Celestia fell to the ground. Naruto lean against the rock, crying before he looked at Celestia. Then, his eyes turned blood red.

"You... you…" Celestia turned to look at Naruto as his orange aura flared "I'm going to make you pay for hurting my older sister!"

Before Naruto could attack, he was surrounded by golden magic and Celestia stared right at him.

"You are the last pawn of Astelle. Time to rid Equestria of you!" Celestia shouted in anger.

"Do it, you sister traitor!" Naruto shouted at Celestia in cold and feral hate "Seal me within that painting as well with Astelle!"

"No, I have somewhere worse for a demon like you." Celestia said as her eyes began to glow white "I, Princess Celestia, banish you to the deepest and darkest place of Tartarus where you will be there forever!"

"I will avenge Astelle, Celestia!" Naruto shouted in anger before he began to fly away like a comet "I WILL AVENGE ASTELLE, CELESTIA! ONE DAY, I WILL RETURN AND WHEN I DO, YOU WILL REGRET NOT SEALING ME AWAY WITH ASTELLE! I WILL RETURN!"

Meanwhile…

A comet of orange approached the Pit of Tartarus and it began to dive down torwards the pit. It began to continue dive even passing a bunch of cells before it reached to the bottom before it passed through a red portal that was opened at the bottom of Tartarus and it closed when the comet passed through.

When the comet appeared in another area of Tartarus, it approached a dark tower that looked like it was upside down and it landed in the middle of a throne room. The comet began to form into Naruto, who was kneeling down from the ending of the banishment spell. He opened his eyes, revealing them to be normal. He noticed in front of him was a weird creature and a lady.

"Yami." Naruto greeted with a nod before looking a curious "Who is that with you and why am I here?"

"I brought you to the Netherworld, the bottom of Tartarus." Yami said with a smile "As for who is with me, this is Gnarl." The said creature bowed a bit "He is the minion master and advisor for the Overlord."

"The Overlord?" Naruto asked to her.

"Indeed." Gnarl said with a smile "I have served Overlords and have worked with the Netherghul, candidates of being Overlord. However, they wiped themselves out and we minions were going to find a new Overlord but Yami approached us, telling us that she had a candidate for being a Fifth Overlord but the First Overlord in a new world. So we agreed and here we are."

"What is the Overlord?" Naruto asked to Yami.

Yami smiled "One of my favorite creations in the multiverse. It is a title of the dark and powerful being who ruled territories of the world. They are usually savage warriors, have the loyalty of Gnarl, can summon and control armies of Minions through a special gauntlet, and can use powerful dark magic."

"Let me guess, I am going to be the next Overlord?" Naruto asked and both Yami and Gnarl nodded.

"Yami has shown me your potential, with proper training and more, you can be the next Overlord." Gnarl said with a grin "The one known as Celestia may believe that she is safe, but she underestimates the forces of evil. After all, evil always finds a way."

"I will return, but for the next 5000 years, you will be trapped in the Netherworld." Yami said before smiling "When the Mare in the Moon is freed, you're imprisonment spell will have weakened to the point where you can walk freely out of Tartarus without setting off Tartarus' alarm spells. By then, you will be more than ready to return to Equus to exact your well deserved revenge against Equus for its' misdeeds to you."

Naruto nodded before Yami faded away and he looked at Gnarl and gave a fanged grin "When do we begin?"

If you have read the top, I want your suggestions for being the Four Netherghuls and the Harem Votes. Also, once we have the votes for who the four Netherghuls will be, we need to know what type of magic will they have. I'm also adding an OC known as Zrixess but she will be the purple Succubus Kerrigan skin, the Queen of Suffering. The Succubi are demons locked inside Tartarus by the founders of Equus and have lived for many years.

Note: This chapter is a prologue of the Overlord Maelstrom. If I received enough requests to do this story, do note that it will take some update time on The Equestrian Maelstrom to work on this. I uploaded this story because I've been dying to upload a related story to Overlord.
