With Chaos magic surging through her body, making Chrysalis more powerful and bigger than ever (Not without her help of course!) a shadow covers Canterlot mountain as her mighty hoof reaches down and tears the entire capitol from it's perch on the side, fitting neatly in the frog of her hoof as she raises it to her eye with a playful smirk.

"Helpless!" Chrysalis proclaimed, accusing both of the alicorns with a happy voice.

Sending a fleet of knights out from the castle, winged and charging her, Celestia called out, one final attempt of reason against the backdrop of ineffective spells. "Why are you doing this Chrysalis?! Are there not peaceable terms that we could reach if we tried? Any outcome that doesn’t lead to this?”

Chrysalis simply smiled, chaos almost a part of her right then. "I’m doing this for fun! That’s all
there is to it, and I’m having a lot of fun. Don’t interrupt."

They clearly weren't fit to be rulers if they couldn't protect Equestria or their own city from the sheer might of Chrysalis's power. That was the simplest rationale, but also the truest. Watching them realize how powerless they were was a decidedly enjoyable process. She was glad she’d chosen this method.

Desperate to stop her invasion, Luna and Celestia deployed yet more guards that spring to the skies, valiant and armored. Flapping toward the large mounting mare to stop her attack, they gave a flury battle cries. “Hahahaha. Adorable!”

Chrysalis watched the guards flutter like fruit flies around her. This was such a wonderful feeling, so liberating! Cackling, she simply breathed out and the heavy rush of air swept the guards away in one motion. The guards cried out and tumbled into some clouds and then swirled away, twinkling like mites.

Behind those guards were cannons, which fired at her rapidly with shells until the massage of the cannonballs against her coat began to irritate her slightly. Picking them all up at once with her magic, she twisted and combined the metal of them together, scrunched them all into one ball, and conjuring the same baseball bat from earlier, launched it in the same direction she’d previously sent Ponyville.

Chrysalis continued her laughter, rearing up briefly and lifting Canterlot higher. Giggling, Chrysalis attracted Canterlot to her and shifted, pressing the peak to her bulging glistening rump.

Twisting her rump back and forth, Chrysalis felt the peak to crunch and splinter off. Canterlot was under her control, crumbling under her pressure. While Celestia and Luna cried out in horror, Chrysalis twitched her thick cheeks and crunched away more of Canterlot with ease.

Chrysalis is powerful, surging with size and strength as she destroys Canterlot and leaves it as rubble, all as Luna and Celestia expend every last drop of their power levitating ponies away from the ruins, saving them from their fate.

Chrysalis almost needed a moment to recover after realising what she’d just managed to do, the feat she’d accomplished, finally. She’d… won. Even through all of this, no matter how self-assured she was, there’d been the voice in the back of her mind reminding her of her past failures, telling her not to get her hopes too high…

But that didn’t matter anymore. This was it. She’d finally done it. The hard part was over. Victory was hers, and all hers…

And the fun part was now.

Every doubt expelled from her mind, riding high and grinning from ear to ear, the mare turned and surged even farther upward, swelling greater in size

Expelling some magic, Chrysalis calls out to her fellow changelings, seeking to grow them as well. It seemed only fitting that every changeling share in at least a portion of her power. She was a great and giving queen, after all

"I am the new ruler of Equestria, and everything else! Hear me and my people!" Chrysalis announced, voice heard by all due to her unbelievable magnitude. She didn’t even need to use magic to amplify it; she was simply that large now.

Happy with her power and her choice, Chrysalis brought some changelings close to her size and then began to dance powerfully over Equestria, stomping and crunching whatever met the bottom of her hooves. It was a simple gesture, one she might’ve previously considered beneath her royal station, but none of that mattered anymore. Who was there to judge her? Who would dare consider themselves in the position to? She could do anything she wanted now, and there was no pony or any other creature that would ever be able to stand in her way again.

And so she danced, and she danced, and the royal sisters watched her, caught between lamenting their destroyed home and usurped kingdom and marveling at Chrysalis’ impressive movements.

The other changelings danced as well, swaying their hips or rearing up, enjoying their own surge of size. Below the mountains and hills are crushed and splintered, while ponies scatter in panic but miraculously remain unscathed.

"Let us all dance to celebrate the new ruler of Equestria!" Chrysalis cried, rearing up and smashing down her hooves happily. Each stomp was a new mark in her new home, a home she’d keep for as long as she lived.

And immortality was a long time indeed.

Dancing, the changelings join in, chanting appreciation to their Queen.

"All hail Queen Chrysalis!"

All hail me.
