Changeling Empire

Intro belongs to One Piece

The song starts with all the Mane Six defeating Nightmare Moon, Discord, Queen Chrysalis, King Sombra, Tirek, and Pony of Shadows before a gigantic shadow hand engulfs them.

Cut to the Canterlot with the Wonderbolts soaring over, and the Mane Six running on the road together. Twilight gets ahead of them, and is then seen on flying to the sky. Queen Chrysalis is then shown walking in a foggy setting with her hooded cloak on. She then starts running as the screen flashes.

The scene change to Starlight running in the hallway, followed by Luna blasting a shadowed Miasma in the dungeon, Shining Armor clashing with Gold Star in the courtyard, Cadance unleashing her magic in the Treasure Room, Spike and CMC inside a giant cake, and Celestia facing off against Empress Irian.

Back at the Ponyville, where the Mane Six exits the castle and presents their friends a basket before cutting back to a stormy Changeling Imperial City, where several members of the Changeling Royal Family and their allies are seen. White Changelings are shown before their meeting with the Equestrians, as their queen smiles at the camera. Then flashcards of Sunburst, Flurry Heart, Thorax, the male friends of the Mane Six, followed by the females. The scene change to Starlight and Chrysalis facing off in the rain, both injured and with Chrysalis' body cracking as if it is shedding. The screen flashes again, showing the Equestrian flag in the wind.

Cut to the Starlight, Sunset, Moonlight, Trixie, and Tempest Shadow wearing special armor, showing off their enhanced magic. It then goes to the Changeling Six, lining up Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie Pie in front of Empress Irian. It then moves to show Celestia and Luna awakening their full potential with a shadowed Lauren Faust behind them.

The opening finally cuts back to the Canterlot, panning over the Mane Six standing in a line with smiling Twilight at the end of it.
