Equestria.
The City of Canterlot.
A wedding was slowly taking place, but it was sabotaged by an evil queen who was the ruler of her swarm, and had impersonated the bride. She had also put the groom under a spell, as his eyes were as green as a lime. After she foolishly revealed her true self and announced her true intentions on the altar, she knocked out the princess of Equestria with her laser blast, making her fall to the floor, along with her crown. That shot up a flicker of light and caught our attention very quickly.
"What the...?" asked Ark Royal, who was riding on one of her RAF Spitfires, and jumpy at the flicker.
"There!" I called. "That's our target! Let's drop in and give them a big surprise!"
"We're right with you, Enterprise!" replied Hiryuu.
With that, our planes made a 91.2-degree turn northward to engage the unknown targets. Meanwhile, inside the castle, after the wedding attendees had evacuated, a group of six triumphant and heroic ponies: two unicorns, two earth ponies, and two Pegasus, ran outside across the city to retrieve powerful items they could use to stop this invasive attack on the castle, and the city.
But as they ran closer, they were stopped by these monsters, and were completely surrounded, both on the ground, and in the air, with no chance of going any further.
"Looks like we're gonna have to do this the hard way," declared one of the Pegasus that had a rainbow-colored mane and tail.
Then, suddenly, out of nowhere, a strange light blue and white shape zipped through the skies like a rocket, swooped down and plowed through each of the monsters! When it re-emerged, one of my Dauntless SBD dive bombers caught the attention of the six ponies, and the swarm as it climbed back in the sky.
"What the hay was that?!" cried the orange earth pony.
As we were closing in fast, the white unicorn pony said, "Not what, darling... who! Look!"
"I see it, but I don't... sweet Celestia, look at their speed!" cried the purple unicorn pony.
"Alright, we're here!", I called out, "All planes engage the targets in the air! Any of you ships with swords, and those of you who can fight, get on the ground and help those six creatures!"
And so we did. Atago, Takao, Zuikaku, Prince of Wales, Javelin, and Ayanami landed on the ground, drew their swords and spear, and then charged at the invaders to attack.
"Who are you?" asked the yellow Pegasus a little timidly.
"We'll explain later," replied Zuikaku. "But we're here to help you save your city; let's go!"
With no need to be told twice, the six ponies followed and joined our fleet to help attack. The Cleveland sisters were gaining the upper hand by attacking most of the swarm, while some of the other ships from the Iron Blood and Royal Navy did most of their attacks with their turrets and their hands and fists.
"11:00!" Indianapolis called out.
"Ja, I see them! Feuer!" yelled Bismarck as she scored multiple shots.
"Take zat!" cheered Z23 as she also scored some shots.
Among them, the heavy cruiser Prinz Eugen was battling physically. Using her shark-like jaws (like Doc Ock using his tentacles), they each bit and ate one of these invaders after another. As some charged down towards her from the air and took a shot, she blocked them with her armor belts.
"Guten tag, Herr flying objects. Having fun yet?" she teased. But they just kept on coming from all directions.
By now, the four Sakura Empire ships and the Royal Navy vessels have been gaining the upper hand, and even the six ponies were amazed at their fighting style.
"Go on!" called Atago. "We've cleared the way long enough for you to keep running!"
"Yes," agreed Ayanami. "We'll keep them at bay and hold them off long enough for you to get what you need!"
The six ponies obliged and made a run for it. "Thanks for your help against these changelings!" called the pink earth pony.
"Changelings? So that's what they're called," thought Wales as she and the allies kept on battling them.
Meanwhile, we all scrambled one plane after another: SBDs, F4Fs, Zeroes, BF-109s, RAF Spitfires and Swordfish... but though we tried our hardest and engaged the changelings in the air, we were all blown out outside of the sky. We managed to land safely on the ground, but while we were hopelessly outnumbered, we kept on fighting to save the kingdom.
To make matters worse, by the time the six ponies reached their destination to get the items they needed, they were once again surrounded by changelings everywhere.
With no other option, the six ponies all had no choice but to surrender and be brought to the queen on the altar in the castle.
