How The Mean 6 should have ended

The morning brings more bad news, The Empire is just smouldering ruins, only The Crystal Palace remains in one piece and even then that is barely standing.

Rainbow Dash looks around her cover, she'd been taking care of Scootaloo the whole night with Flash Sentry keeping her covered...a quick glance to where his cover used to be confirms that he won't be helping any more. She thought it couldn't get worse until...

"Their defences are broken, destroy them!" It was Chrysalis yelling out, what followed sounded like a wall getting ripped to shreds, Rainbow peeked over her cover to see the changeling army advancing. Then she looked up...and saw an airship.

Celestia was personally commanding the helm of the ship, sending it on a fly over of the front lines "Soldiers, destroy them!" she commands as several heavily armoured unicorns jump from the ship, firing high powered spells at whats left of The Mean Six, the first few spells connect, destroying both Evil Fluttershy and Evil Applejack.

"What is this?" Evil Twilight yells, her power dwindling she fires spells back at them, hitting a few of the Unicorns, but only wounding them, they all attempt to counter-attack, but get dealt with quickly with a few spells, leaving the unicorns motionless on the ground.

Celestia stands tall just inside the walls, observing the chaos being wrought "Chrysalis must be stopped...no matter the cost" with that she took off in a gallop, then flight whilst staying close to the ground, zipping through streets, past the destruction. Soon she came up behind the changeling army, who were pouring through the breach in the wall, Celestia started charging through changelings, one at a time, crashing into them so hard they flew off their feet. Evil Twilight was next in her path, but she noticed the huge white alicorn flying right towards her and leapt out of the way, using her wings to propel her into the air.

The next set of changelings were more prepared though, they'd turned and were pelting Celestia with spells, most of which simply bounced off of the goddess, she then slammed her feet into the ground, using the force to leap high into the air and sailed over the army, blasting spells at any changelings that dared stand against her.

Celestia then entered the palace, finding Chrysalis just inside "Celestia?" The bug queen said in an almost scared tone.

"Chrysalis...at the end of this day one shall stand, one shall fall" Celestia said, standing tall and regal, wings spread wide and her horn aimed low.

"Why would you throw your life away so recklessly?" Chrysalis taunted

"That's a question you should ask yourself" Said the princess, preparing a spell.

"No...I'll destroy you once and for all!" She cried, leaping forwards and tackling Celestia

"I've gotta help Celestia!" Rainbow yelled, seeing the fight start from afar

"No Rainbow, you'll just get in the way!" Twilight called out, trying to reel her friend back in.

Celestia threw Chrysalis off of her, sending her flying into a wall, seeing an opportunity to do some damage the changeling queen picked up a fragment of wall in her magic, throwing it back at Celestia, she had no time to react and it hit her square in the side, sending her reeling back in pain.

Chrysalis attempted to follow it up with a spell, but Celestia ran up, tackling her into a wall and cracking the Queens bent horn. Celestia backed away, pulling the shard of rock out of her and throwing it aside, but not before Chrysalis picked up a discarded sword and ran at her, slashing at her side, making the wound worse. Celestia backs away again, finding herself at a ledge when Chrysalis leaps into the air, using her wings to assist, then nosedives head first, Celestia simply punches her aside with a hoof, sending the queen flying onto her back. Celestia advances but then Chrysalis kicks her onto her back and then grapples her, trying to claw at her face with a hole filled hoof.

"I will tear you to pieces!" She cries, Celestia then overpowers her, throwing her a good distance away, stunning her a little. She then clutches at her side with a hoof, before walking over to Chrysalis, who quickly notices a discarded crossbow...

"No more princess, please! Mercy!" Chrysalis cries, her cracked carapace creaking with every movement.

"You think I should give you mercy? After all the lives you've taken the past two days..." Celestia starts while her defeated opponent starts crawling towards the crossbow. She reaches for it and...

"Uh uh Chysalis!" Rainbow comes out of nowhere, rushing for the crossbow

"Get out of the way Rainbow!" Celestia cries, not able to find a clear shot as Rainbow and Chrysalis struggle for the crossbow, the larger creature soon overpowers the Pegasus and uses her as a shield as she unloads enchanted arrows into the alicorn.

"Yes! Fall FALL!!!" Chrysalis yells out in glee, watching her enemy get perforated with arrows, when she finally collapses to her knees she throws her shield away like a ragdoll and walks over to Celestia "It's over my little pony..."

Celestia is full of arrows and even breathing seems hard, but she tenses up and with one last show of force "Never!" she yells, bucking Chrysalis who loses grip of the crossbow...she attempts to fly to control her decent, but her delicate wings have been ruined, so she simply flies over the edge, hitting another ledge and continuing to fall, before coming to a violent stop on the ground, where she's greeted by one of her last living minions.

"How does it feel mighty queen?" Evil Twilight chuckles, kicking the beaten changeling before walking away "Retreat! Everypony, retreat!" She yells and the remains of the changeling army heed her command.

"Celestia did it, she turned the tide..." Twilight says, marvelling at the retreating forces

"C-Celestia...I'm sorry..." Rainbow sobs, falling to her side, the white alicorn is alive...but remains motionless.
