Blue Steel Yamato and the Prince of Harmony

Note: This is my first fanfic. There’s some grammar errors.

Chapter 1: Prologue
In a world called Equestria, a world that was populated by wonderful creatures such as Earth ponies, Pegasus, unicorns and rare alicorns. The two rulers of Equestria is Celestia the bringer of the day and her younger sister Luna bringer of the night, along with them the mane 6 and Zipang’s prince Imperial Crest and his friends Bel Ice, James Black Fire, Brady Blue, Striker Cobra, Cloud Roller, Wilson Kail and Crest’s brother Imperial Wolf. With all of them, they all brought peace all-around of Equestria and other great nations. But since the 2 Great Wars started everything has changed, many nations fought bravely but when the war ended all the nations have lost many lives and most of its military power. In a few months some nations were recovering from the war and Celestia Luna were absent on a secret meeting to find another way to prevent any conflict within the nations. The New United Equestria Alliance is formed to find a way to bring peace within the nations. Until one fateful night, history has repeated itself once again.

(Soundtrack for the whole chapter: Cadenza Beginning)

At the Atlantic Equestrian Ocean, in the cold evening a battle has begun with a horde of Nagara Class cruisers attacking a ship appeared in a white and blue colour scheme with golden gun barrels and the ship appeared to be the Super Battleship Yamato which was controlled by the bringer of the sun Princess Celestia. As horde of the Nagara getting closer to her ship Celestia uses her magic to deactivate all of them and leaving the ships dead in the water and colliding at each other. Then a ship appeared in midnight blue and orange colour scheme with golden gun barrels and the ship is identified as the Super Battleship Musashi rams through all the dead Nagara vessels. Musashi was controlled by Celestia’s younger sister and bringer of the moon Princess Luna.

Celestia calls out for her sister “Luna!”

As Luna wiped her tears away from her face. “Celestia, you are being disobedient to our royal family”, Luna felt a force around her and she changed into an old enemy Nightmare Moon. Then Musashi’s hull opens vertically and the ships main guns pointing broadside and starts to activate its Super Graviton Cannon.

“Therefore I will bring Equestria to eternal darkness and everypony will bow down to my subjects and I will annihilate those who will stand in my way”, Musashi’s Super Graviton Modules port side starts to light up and generating a lot of energy that’s ready to fire at the Yamato.

Celestia denied Luna’s words “I won’t let you!”, Celestia activates Yamato’s mirror-ring system to avoid impact and Yamato opens its hull vertically like Musashi and the ocean opens creating a huge space making both Yamato and Musashi flying and Yamato releases 8 of its Mirror-Ring Modules and levitates around Yamato and creates 8 portals.

Nightmare Moon commanded the Musashi to fire its Super Graviton Gun to the Yamato but all the Graviton Energy is being sucked by the mirror-ring system.

Celestia questioned to Nightmare Moon which was no longer Luna “Were supposed to be together and bring balance, but why you’re doing this?”

Nightmare Moon answered to her “I’m trying to free myself from this acceptable feeling, just to deny this feeling…….” Musashi’s engine bursts in full speed and propels to the Yamato at maximum speed while firing her Super Graviton Gun.
Nightmare Moon finished her speech and opened her red eyes “I would destroy everything that comes in my way”

Celestia responded to her in concern “Stop, it!” The Musashi rams the Yamato causing a contact impact on both ships but Yamato’s Klein field is too strong to withstand Musashi ram attack.
Nightmare Moon knows the Musashi has secret trick and she activated Musashi’s laser beam that’s hidden underneath the tip of the Musashi and destroys Yamato’s klieg field and destroys one of Yamato’s Super Graviton Gun modules.

Celestia upon the bridge of the Musashi where Nightmare Moon is standing and noticed a human that supposed to be dead standing beside Nightmare Moon “Crimson Shouzou”, she looked down in utter defeat against her sister and Nightmare Moon commanded Musashi to relentlessly attack the Celestia’s ship in close range combat. During Musashi’s close range attack blowing up other Super Graviton Gun modules and Yamato’s Mirror-Ring is disabled making the 8 portals vanished along with Musashi’s Super Graviton Gun energy.

Nightmare Moon sees the despair of her sister but all she sees is a total victory against her and then she activates Musashi’s Super Graviton Gun Modules to levitate and pointed at the Yamato. Then Musashi fires all its Super Graviton Gun hitting the Yamato heavily. During the attack a lot of explosions occur around the Yamato and suddenly a huge explosion erupted. Many debris of the Yamato were sinking slowly and 8 submarines entered the explosion site and one of them is an ally to Celestia which is the I-401 commanded by a young alicorn named Imperial Crest and his friends Bel Ice, Brady Blue, Striker Cobra, Cloud Roller and Crest’s brother Imperial Wolf to rescue Celestia. As Celestia drowns and feeling weak she starts to cry and questioned herself “Luna, why?”

As she sees the I-401 that’s about to rescue her. She uses her magic and sends a beam of yellow and rainbow magic force around the I-401 and gave a message to Imperial crest through telepathy. After Celestia’s message she uses spell that will make Imperial unconscious.

Then Celestia used her magic to give a message through the I-401's intercom. “Please get away from here soon as possible Crest’s crew”.
Celestia used another spell and it causes a big flash in the I-401's bridge and everypony went unconscious as well and Celestia uses another magic to force the submarine to get unnoticed by Nightmare Moon. As the I-401 disappears from the area Celestia's body disappears and the mighty battleship has sunk once again in the Atlantic Equestrian Ocean. Since Celestia was gone and the Yamato is sank, Nightmare Moon can now control the whole entire Zipangnese Fleet.
