How The Mean 6 should have ended

Cadence felt a shudder, like the whole airship shook "Wh-what was that?" she asked, looking around, suddenly the room felt a lot more cramped.

"Relax, it's probably just turbulence" The helmsman, a cyan unicorn named Lyra, said with a casual wave of a hoof. That seemed to calm the princess's nerves, until there was another shudder.

"What was that?" Asked Roseluck the navigation officer in a bit of panic, what followed was more shuddering, then a wall to the back of the room getting blasted in, before anyone could react something powered through the wrecked wall...

"Crysalis?" Cried Bon Bon, the first officer, she was the first to turn, running out a little "Changelings!" she yelled

Crysalis reared up on her hind legs wings spread, with Evil Twilight Sparkle and a platoon of Changelings flanking her "Die Ponies!" she yelled, her horn igniting, sending a blast of magic right at Bon Bon who staggers, then falls to the floor motionless.

The rest of the crew, Cadence and Applejack remain in cover, Lyra being the first to risk firing a bolt of magic, that just misses everything. She's then cut down by a spell from another Changeling, piercing right through her and hitting the windshield.

Another Unicorn and Applejack both leap out of cover, the Unicorn tossing spells left and right, Applejack kicking debris at the attackers, sending them back into cover, until Evil Twilight and three other Changelings unleash a flurry of attacks, sending The Unicorn flying back, Applejack takes the brunt of the assault, still just about standing, before a second volley finishes her off.

"This was almost too easy Knockoff Sparkle" Crysalis boomed, it was almost ecstasy, this plan she'd been working so hard wasn't just working...it was flat out easy. Behind her Evil Twilight cringed at the name, Crysalis never forgot to remind her what she was...but she knew she was more than that, than her...though, it was better to bide her time...to be a good little minion.

"Much easier my Queen, than attacking the real threat, Canterlot Palace" The grey purple Alicorn both suggested and warned, in the hopes of suggesting her own plan.

"You're an idiot Knockoff" She said dismissively "When we slip past security in their own airship and destroy The Crystal Empire, The Mane 6 will be vanquished forever!" Crysalis announced with pride.

That's when Cadence made her presence known, jumping out from cover, almost overwhelmed with emotion "No! You can't!" She cried, trying to flare up a spell

"Such heroic nonsense" Crysalis chuckled, before unleashing a spell right at the pink mare...and another body joined the rest as Changelings took up the crews positioned and continued on course.
