Meanwhile the I-401 set sail and made it to the Atlantic Equestrian Ocean where the Nightmare Moon’s fleet is located. The crew discovered something that is devastated.

Cloud announced “The seafloor is giving Iron Material response. Is this”

The I-401 passes by a wreckage a superstructure that looks familiar and the superstructure appeared to be the Yamato. The wreckage of the Yamato, the bow is separated and form the mid-section to stern is still intact but half of it is nearly broken up in two due to the impact when the vessel hit the seafloor and many debris is all over the seafloor.

Mel looks at the monitor and sees the Yamato “Oh my gosh, what a mess did Nightmare Moon cause?”

Suddenly a red/orange beam speeds up to the I-401. A beeping noise was played and Cloud announces “Graviton reading!” the red/orange beam went pass the I-401 as a fire warning.

Cloud announces “Klein Field saturating at 96%!”

Brady commented “And it’s just one hit!”

Crest knew where that was attack from “It’s the Musashi controlled by Nightmare Moon”

At the Super battleship Musashi at the top of the bridge two figures standing Nightmare Moon and beside her is Crimson Shouzou.
Nightmare Moon commented “I never thought you could reach here. Disappear now. I will destroy you here just like Celestia” The Musashi launches missiles and Nagara cruisers fires their missiles as well and all the missiles dive down in the water and hits the I-401 but the I-401 Klein Field is still active.

Mel shouted “Nightmare Moon, Wolf and Crest’s father….Crimson Shouzou believes that having a meeting with you could help all of us bring peace to Equestria, so does Crest! Please! Can you…..Can you give us a chance to negotiate?”

Imperial Wolf joined in and said “Me and Crest’s father trusted you and we believe he still does”

Nightmare Moon smirked and said “You’re not Crimson” all the Super Graviton Cannon modules emerge from the Musashi levitating around the ship and started to light up and aims at the location where the I-401 is and all the Nagara Cruisers continues their attack on the I-401. “A fake Celestia, a fake Crimson. I’m tired of playing puppets”

Cloud announces “Multiple Super Graviton Cannons deploy!” then the SGC Modules pointed down at the location where I-401 is.

Crest gets off his seat and leaves the bridge and Mel asked “Crest!”

Crest bolted through the interior that leads to the exit of the sub and he uses a spell on himself so he can breathe and exits the sub and stand on the bow of the I-401 and Crest puts his hoof on his chest. “Even if I disappear, my memory will remain in everypony’s heart” the SGC modules made a big flash and fires a beams of Graviton energy rain down heading towards the I-401. “So I have decided”
Then a strong energy of blue and yellow colour including rainbow colour surrounding Imperial Crest and creates a huge shield showing an emblem of the burning sun and the shield expands stopping all the warheads and Musashi’s SGC attack. Then a spread of glittering iron material went to the damaged parts of the I-401 and repairs the superstructure.

Striker commented “It’s…”

Brady asked “What just happened?

The wreck of the Yamato is starting disappear in a cloud of Iron materials and it all goes to the I-401 and some debris was floated and approaches to the I-401.The monitor shows the word Yamato and displays the ship and its weapons and Striker announces “I-401 system is reconstructing, the armour and weapons are not of same rank”

The parts of the Yamato continues joining up with the I-401. Meanwhile in the I-401 engine room Wolf was surprised “Guys, can you hear it? Graviton engines are upgrading. It’s too much….” Wolf looks at the monitor displaying all the engine status.

Imperial Crest then got swallowed up by the energy. The at the surface a ship emerges from the ocean revealing the itself as the new Yamato and the I-401 appeared inside the ship and a shining figure appeared on the top of Yamato’s bridge and it appears to be Imperial Crest but his wearing a white robe and an emblem appeared on the centre of his robe showing the elements of harmony emblems and both Crest and Celestia’s cutie mark. Then Crest’s wings expanded revealing an extra wing which is white coloured behind his blue wings. Then he expanded both of his hooves and 16 portals appeared around the Yamato then Musashi’s fired its Super Graviton Cannon but was absorbed by the 16 portals that the Yamato has created and another portal appeared on front of the Yamato facing the Musashi. Then a beam of orange appeared hitting the Musashi but didn’t take any hit due to her strong Klein field.

At the Musashi, Nightmare Moon was complete shock that the Yamato is back and thinking that Celestia has returned. “Celestia?”

In a void showing a clear huge beautiful valley with lakes and small green islands and huge blue glass looking pillars surrounding the void. Nightmare Moon appeared floating in the void and changes her appearance to Luna and sees her sister and was surprised and “Celestia!. Then she flew slowly towards her sister “Finally…I meet you at last!”. Then Celestia extends her forehoof and a bunch of grey coloured ships appeared all around the lakes glowing with red neon but changes to blue colour.

Meanwhile in the battle area between the Yamato and Musashi, all of Musashi’s escort cruisers attacking but ceases and the cruiser’s neon changed from red to blue.

In the inner bridge of the I-401/Yamato, the crew witness on the main monitor displaying all the cruisers showing the signature and Cloud announces “Nightmare Moon’s vessels with attacking signature have become our allies”

Brady questioned “How did this happen?”

Mel announced ‘We’ll seize Nightmare Moon’s command power...and negotiate later”

At the top of the Yamato’s bridge Imperial Crest answered “Agreed Mel”

Meanwhile at the void Nightmare Moon/Luna continues to approach Celestia and said “Welcome back, Celestia. I’m so happy. That pony has been eliminated, right?”

At the battle area the Musashi approaches to the Yamato on the side, when both ships get closer both Musashi’s and Yamato’s main, secondary and AA guns pointed at each other. Then both ships fired their weapons at each other. After both ships went pass by each other and stops both its attack then Musashi moves to starboard then fires its main guns again then hits Yamato but the Yamato didn’t take any hits but the attack bounced off.

Meanwhile in the void Celestia was quietly staring at Nightmare Moon/Luna and NM/Luna holds her hoof and asked “Celestia, you shouldn’t do so, Celestia. Since you killed him just to see me, you’re no different than those ponies who killed Crimson Shouzou” then NM/Luna stated “An older sister who was defeated by me. I shall defeat you once again”

Then Celestia speaks with Imperial Crest’s voice then huge flash on Celestia making NM/Luna can’t see and Imperial Crest appeared and asked “I have an important message to tell you. Celestia loves you” after those words NM/Luna was shocked that she thought that Celestia get rid of him and she changes back to Nightmare Moon and flies back away from Crest.

“No, who are you?! Which one are you?!” Nightmare Moon questioned.

Imperial Crest asked “Now I understand. Celestia had always loved you”

Nightmare Moon ignored his words and shouted “You lied! Celestia! Get rid of this puppet quick!”

(“Music will suit this” Cadenza End by Masato Kouda)

Imperial Crest asked Nightmare Moon “Back then, Celestia couldn’t hurt you. No…she gave up on you. So now, through my existence is to protect my country through those years and now, I will stop you”

At the battle area Musashi keeps attacking Yamato but Yamato’s Klein field is still strong that Musashi’s attacks keeps bouncing off, and Yamato moves towards the Musashi. Inside the hull of the Yamato where the I-401 is located the graviton cannon starts to glow.
Cloud announced to the crew “Graviton Cannon charging up!”

At the void.

Nightmare Moon argued “‘Stop me’ you said? You don’t know anything”

Imperial Crest replied “I do. You don’t have a place where you belong to. Nothing can pacify your anger ever since then. In fact, she should’ve been by your side all the time”

Nightmare Moon little bit sob and shouted “You’re wrong! I didn’t feel angry! Ponies are foolish that killed your father denying peace so I attempt to show them fear and destroy them!”

Imperial Crest asked “Luna, ponies possess a strong priceless power. I discovered it after I met James, Cloud, Striker, Brady and Mel and other ponies that become friends with in my life. The power of heart holds infinite possibilities. We have a heart too. If not so, she wouldn’t have treasured you this much”. Crest then stretched out her hoofs and asked “Luna, I will accept you into Celestia’s heart. After all, I’m your friend as well”

Nightmare Moon thinks and thinks and have a flashback of the good times she spent with Celestia when they were young and Celestia helping her out. Then Nightmare Moon shuts her eyes and said “Hate, hate, hate, hate!”

At the same time in the battle area nightmare moon keeps repeating that word hate and then Musashi stops and the ship faces towards the approaching Yamato and Musashi separates all its SGC and MRDS modules.

Nightmare Moon felt all anger and she then starts to sobbing “Hate, hate, hate, hate…” All the MRDS modules levitates around the Musashi starts to glow and all the SGC modules facing towards the Yamato and Nightmare Moon keeps going “Hate!” then she screamed at the top of her voice “Everything should just disappear!”. The Musashi activates its graviton sabre gun which was located under the tip of the vessel then one huge portal appeared under the Musashi and then the portal divides itself in two one at the bottom and one at the top and then the Musashi fires all its SGC cannon and the attack speeds up towards the Yamato.

The Yamato speeds up towards the Musashi activated its Klein field to brace for impact while it’s charging its SGC up.

Cloud announced “Musashi deployed Mirror-Ring system”

Striker asked “Crest!”

Musashi’s attack was bounced off right after Imperial deployed his shield including the Yamato’s Klein field and the ship keeps speeding up giving Nightmare Moon a complete shock.

“What the hell is he doing?” Nightmare Moon questions.

Mel encouraged Crest “Don’t back down! Charge!”

As the Musashi’s attack was cancelled including Yamato’s Klein field the Yamato slows down towards Musashi then both ships collided on the sides. When both of the ship’s bridge meet, both Imperial and Nightmare Moon looked at each other face to face once again and due to Musashi’s mirror ring system portal’s gravitational pull. The Yamato ends up falling into the darkness of the portal and the ship disappears into the portal and the portal closes and the open ocean disappears making all the waters rush into the empty seabed of the battle area leaving the Musashi floating still intact and Nightmare Moon ends up crying and laughing over her victory.

Meanwhile in a space and time dimension the Yamato was travelling the firing chamber of the ship starts it charge up. Imperial Crest’s horn starts to glow with rainbow colour aura mixed with yellow and blue.

Imperial Wolf announced the percentage of the weapon “Nearly to 250% the weapon is nearly ready!”

Mel announced “Crest, calculate her coordinate! This is chance for u to use the elements of harmony! Open a portal above the Musashi!”

Meanwhile at the Atlantic Equestrian Ocean went back to normal and its dawn and the Musashi rested its power and suddenly a huge blue portal appeared above the ship and on the bridge of the Musashi Nightmare Moon looked up and was shocked. In the portal a huge blue light combined with rainbow colours glows and the Yamato appeared form the portal dives down bow first ready for the final blow.

Wolf announced “Ready fire!”

Mel shouted “Crest let’s do this!

At the same time Crest shuts his eyes for a few seconds and he remember his past all his good times with his friends and family as he knows his fate. He opens his eyes and points his horn at Nightmare Moon ready to use the elements of harmony. 'Fire!" he shouted.

As the Yamato gets closer to the Musashi, a big blue of blue energy appeared on front of the Yamato and Crest’s horn charges up and at the same time Nightmare Moon uses her magic to deploy her shield including Musashi’s Klein field. Imperial crest shoots a beam of rainbow from his horn and at the same time the Yamato fires its weapon sending a huge blue beam combining with the elements of harmony hitting Musashi and Nightmare Moon’s created shield and causes a huge pressure on the shield. Musashi and Nightmare moon’s created shield could not hold any longer due to the attack was close ranged and the shield was destroyed, Yamato’s attack finishes. The Yamato smashes Musashi’s No.2 main gun and continued hitting the deck and smashes through the entire part of the ship causing the Musashi exploding in half blowing in half and at the same time Nightmare Moon saw Imperial Crest sending a beam of rainbow and hits her and she shouted in defeat “NOOO!!!!” causing a big flash. Meanwhile a lot of debris flying everywhere due to the huge impact the Yamato resulting both ships sinking and the portal disappears.

At the void Nightmare Moon was surrounded by rainbow coloured energy and big flash occurred and then her body changed back to Princess Luna but she was unconscious and ends up falling down and Imperial Crest flies down to save her.

Meanwhile at dawn in the same time the Yamato’s stern sinks into the waters as its bow rises skyward and Yamato shoots huge white beam to the sky and causes a white and rainbow aurora glowing all around Equestria. Meanwhile the void disappears brining both Crest holding Luna back to reality and Crest floats near the Yamato and still holds Luna.

“As the controller of the fleet, I contact all ships that’s surrounding Equestria. This war will be prevented. The other nations that has problems with other countries shall end” Imperial Crest announced in an echo telepathy voice.

Meanwhile at Diomede II Islands all of Imperial Crest’s allied stopped fighting noticed the rainbow coloured aurora appeared in the dawn sky.
Frost shouted “Crest did it!” and Mental Model Kirishima hopped with victory. Both Haruna and Wilson looked at the sky seeing a rainbow aurora appeared.

Kotoko was wrestling Ashigara but stopped and looked at the sky “What? Is that Crest?”

Amalthea looked up after she noticed her son’s voice “My son…”

Hiei looked at the aurora skies “What is happening?”

Imperial Crest continues “I command all vessels to withdraw attack. From now on the separated countries that have difficult relation with Equestria Alliance shall end. It’s an order and also Celestia’s command”. After he finishes the rainbow auroras disappears and the Yamato sinks half in the water leaving the ship half sunk. With Mel knew something is not she bolted and exits the I-401 inner bridge.

(Music will suit this. Plays ‘Last Refrain” by Nano)

Ashigara lets go of Kotoko and looks around “What? What?”

Haguro asked “What happened?”

Hiei said “The war ends. Let’s withdraw”

James smiled and looks at the distance and thanked Kongo and then he open his wings and fly from Kongo heading to the Yamato. “You did it, my friend. But something’s not right”

Meanwhile at the Yamato with a huge glass floor above the ship. Luna starts to wake up, as she opened her eyes she smiled sees Celestia and she hold her instead of Imperial Crest “Sister”

Celestia smiled in relief “I’m sorry”

Luna responded “Okay”

Celestia turns around and sees Imperial Crest standing behind them and smiled “Thank you”

Crest smiled at this heart melting sight responded “You’re welcome”

Celestia then creates a huge blue staircase and a portal that leads to their home Canterlot. As both sisters trotted together happily they nearly headed to the portal and Crest looks at them and both of them gave a wave.

Meanwhile at the I-401 inner bridge.
Cloud announced “No sign of Luna just disappeared somewhere”

Striker was sensing something that he’s worried about his friend and questions them “How about our friend Imperial?”

Mel exits the I-401 which is still underwater and swims fast and then she surfaced and takes a big breath and floats looking for Imperial Crest and looks at the bridge “Crest!”

Then Cloud, Striker, Imperil Wolf, Brady exits the ship and they went on a lifeboat and sees Mel and then James appeared and flew down at lifeboat and all of them see Mel finding Crest.

She continued to swim and climbs on a debris and bolted to find him then she sighted Crest “Crest!” She climbs onto the Yamato’s Second Main gun and as she rushed at the middle of the gun turret she saw him appeared with in white robes and extra pair of white wings behind his blue wings but sparkle particles surrounded Crest and he’s standing on the tip of the gun barrel. All of her friends saw him all said in unison “Crest!”

Imperial Crest smiled and speaks to her for the very last time “Mel, and everypony. Thank you for everything”

Everypony went complete shock including Mel and she then bolts because her wings are wet from the swimming and shouted “Crest!

Cloud shouted “Crest! Don’t go!” The rest shouted for his name.

Wolf shouted “Brother, thanks for protecting me!”

James said “Crest, we will remember you!”

Imperial Crest said to everypony “I’m Imperial Crest, everypony’s great friend”

Mel continued to bolting to the gun barrel and shouted and panting “Crest! Don’t leave me!” Imperial Crest starts to fade. “Crest! Crest!” as she bolted to Crest. It was too late for Mel and Crest vanished leaving nothing but sparkle particles floating away to the sky and Mel fell down to her hoof and cried for the loss of her only best friend.

James “Mel get out of there, Yamato is going down!” There was a big rumble on the ship and Mel bolted to the water was rescued by James.
As everypony looked at the Yamato. The bridge slowly sinks along with other debris and James thought to himself and looks at the Yamato “Crest u saved the world for the first time and everypony will honour you and the ponies of the Black Fire Empire” As he finishes he saw everypony crying and he continued sobbing for the loss his friend and looks at the great ship that was resurrected and lived for 5 years and now its sinking slowly into the ocean once again.

As morning hits, most of the ponies, yaks, griffons, changelings and other creatures gathered around in the main city of Equestria celebrating the end of the Great War, Unification of their home countries to Equestria, return of the two sisters and some of them mourn for the loss of their hero. At the NUEA HQ Shining Armour puts down all a file record of Imperial Crest and holds his phone calling some of the country leaders.

James (Narrator): The worst has been avoided. All the Zipangnese Fog Ships all-around of Equestria are withdrawing returning to Zipang
All the Zipangnese ships sailing back to Zipang and Zipang has recovered from a huge battle and Crest’s friend’s sails to Equestria. Amalthea and Kotoko returns to Zipang.

James (Narrator): After that, some countries who obtain freedom, might become confused and rebellious. Perhaps having some ponies might think differently. But, as long as we have will, we can find our own reasons to stay alive. So, someday, everypony will understand each other. Just like how my friend did.

At the Takao nearly sailing to Zipang and Kotoko sighted a flag that is new to her and Amalthea smiled but sad at the same time.
James (Narrator): From now on, ponies, griffons, yaks, changelings and etc. might have a more complicated future. But…we shouldn’t fear of change. As long as we live, we should move forward.

Meanwhile James and Mel looked at the sky and the sun and sees a trail of white sparkly particles.

Mel (Narrator): That was the choice he made for us. I will always believe in it……Imperial Crest
