Without a single word uttered, Luna rocketed down from the air faster than anybody could see—anybody except for Twilight, that is. The draconicorn effortlessly extends her legs and bends them outwards, with Luna flying right through the impromptu arch, with Twilight still holding her haughty smirk. This slight hurdle meant nothing to the princess of the night; she showed her quick response time by immediately swooping around and going for Twilight once more. But, as can be expected, Twilight dodged with ease by this time moving her bottom half to the side and making an arch with her body for Luna to fly through. Luna flew up near the ceiling and situated herself in the air, looking down at Twilight with a vengeful glare.
"Keep trying!" Twilight called out. "I'm sure it will work eventually!"
Luna paid no need the derisory statement, and swooped down towards Twilight, firing off several magic blasts from her horn directly at Twilight. Regrettably, magical assaults were no more difficult for Twilight to dodge than physical attacks; Twilight stretched her body like rubber to avoid each shot, not even moving her feet from their place on the ground. "Your aim is just a little bit off there, Luna. See, the trick is to actually shoot at my body."
Luna ceased her barrage, growing increasingly apoplectic, as it wasn't very hard for Twilight's comments to get under her skin. But even with all her fury fueling her powers, she was powerless against the might of the half-unicorn, half-draconequus beast and her limitless prowess. If Luna desired herself to be even the slightest of a match for this creature, she would need a plan so cunning that not even Twilight could get around it—but how could that be done?
Alas, the ill-starred alicorn had not the time to ponder such a query, as Twilight felt it was now her turn to be on the offensive, "Here: let me show you the proper way to strike your opponent," she stated as she reared back her arm and fired a single magic blast straight at Luna. This time Luna had scrounged together a hoofful of luck, and dodged Twilight's strike with ease. This luck proved itself to really be just a hoofful, as the blast bounced itself off the ceiling, then the wall, and then right back at Luna. The princess only barely dodged the attack this time, as she was preparing a counterstrike and partly left her guard down. Now Luna's defense was back on, and she would be needing it more than ever at this time, as Twilight's ricocheting blast wasn't through yet.
Over and over the blast rebounded off every object it came into contact with; and over and over was Luna evading the shot every time it rebounded back at her. However, she was not the only one facing this danger, as the other ponies and Spike were forced to avoid the blast when it came their way. Twilight paid no mind to the streak of magic as she sipped a cup of tea, the shot flying to and fro around her.
Going by the standard laws of physics, an object that can bounce a multitude of times will eventually be slowed by the force of gravity and stop—but that didn't apply to this object! It continuously ricocheted off and on just about every spot in the throne room, never showing even the slightest hint of slowing down, which was none too good for our heroes, but was plenty good for our antagonist.
Luna's ferocity had caught up with her once more, having had all she could take from the draconicorn's exasperating attack. When the blast headed for Luna again, this time she faced it head on. Without an inkling of doubt, Luna swiftly through her forelegs together at the last second and caught the blast with her bare hooves! Not only were the ponies and Spike shocked to see the princess accomplish a seemingly impossible task, but even Twilight appeared surprised by Luna's feat.
"Well, I say, Luna! That was pretty impressive! I didn't think someone could do that without hands!"
"You should have known better than to underestimate me, monster!"
"Very wise words to live by—too bad you didn't listen to them yourself."
Upon her utterance of these bemusing words, Twilight snapped her fingers. Quicker than even Luna could react, the ball of energy grasped firmly by her hooves detonated, engulfing the princess in a great explosion, and, to the shock of her allies: exploding the princess as well. When the explosion had detonated, the princess was forcefully dispersed into a multitude of dark blue wisps resembling snippets of the night sky itself—not unlike Princess Luna's own mane. These tendrils of magic floated slowly downwards through the air, akin to the falling ash which blankets the sky following a volcanic eruption—but not nearly as traumatic to those who were witness to this shattering display.
"My, my...I've created quite the mess, haven't I?" Twilight sniggered, showing not even the slightest hint of remorse for her reprehensible actions, and everyone else was still too shocked to even respond to her derisive remark.
What went unnoticed while Twilight prolonged her chortling, was that the strands of what was left of Princess Luna began to move about on their own. The strands flew around as the quickly joined together in a swarm, swirling around in a vortex of dark blue night. Then, as swift as the wind, the flock of wisps broke from the vortex and flew straight for the flooring directly in front of the still laughing Twilight. Just before they reached the ground, the wisps turned upwards in an arc. As they performed this action, the wisps also suddenly reformed back into Princess Luna! She flew straight up at Twilight with her front hoof stretched upwards, striking Twilight from under her chin and sending her flying backwards across the throne room! ...at least, that was her intention. Twilight had sensed that Luna was not beaten, and right before the princess could land her blow, Twilight reared her head up and back, the strike barely missing her head. The draconicorn followed through by performing a back flip up through the air and back onto the throne room floor, ending the routine by skidding to a stop on her feet and hands. Luna was both flabbergasted and exasperated that Twilight had dodged her seemingly unavoidable attack so effortlessly, and Twilight made certain to remind the princess of her recurring failure.
"Awww, did I mess up your little plan there? I'm so sorry...but, if you had used a bit more intellect, you'd have realized that you don't stand a chance against me!" Luna was angered at Twilight's incessant affronts, but part of her felt the draconicorn was right. But it didn't matter if the princess could win: all that mattered now as defending her subjects from this horrendous reprobate. She had to think of some other way to outsmart the beast.
While the princess pondered, Twilight noticed the inquisitive eye movement given off by the alicorn. "I spy with my not-so-little eye a pony who thinks they can outfox me. Well, let me tell you something, princess: Ingenuity doesn't win here; magic does! Allow me to demonstrate," Twilight said as her palms began to glow black and purple. Streams of magic of the same color expelled from her hands, moving around Princess Luna, who had her guard on for whatever it was Twilight was planning. Twilight began to spin her forearms around speedily, which in turn caused the streams of magic to spin around Luna, subsequently forming into the form of a sphere. Seeing that Twilight was trying to trap her, Luna quickly tried to escape, but her path was blocked on all sides by the orb of dark magic. This barrier proved to be quite powerful and dangerous, as any physical contact caused a shocking pain for the princess, so breaking through would not be the simplest of tasks.
"You see? Like this! How much good will cleverness do you here? Power is the only way to go, my dear princess," Twilight stated smugly as she laid herself on her back whilst floating in midair.
Without much thought, Luna replied, "Good point," and swiftly enveloped her entire body in a sphere of her own magic, then dispersed it outwards in all directions, subsequently eradicating Twilight's not-so-powerful barricade. "I thank you for the helpful tip, creature; but do not think that was the full extent of my power, as I am saving that for you!!"
"Well, well! You certainly are the tenacious one!" Twilight says as she lands back on the ground "Buuuut, if you're insistent on playing rough, then let's play rough!!" Twilight then forcefully rams her palms straight into the floor, releasing an energy spike which slices through the floor in a rectangular shape. She then uses her magic to slowly raise the slab from the ground, and once it had completely broken away from the rest of the throne room floor, Twilight tossed the wedge straight upwards at Luna with one big heave. Luna quickly counterattacks by flying straight down whilst enveloping herself in a field of her own magic and forcefully thrusting herself through the floor fragment, bursting out the other side. She swiftly made a turn for Twilight, racing towards the draconicorn, fully intent on bringing her down.
Before she could get that chance, Twilight claps her hands together, exploding the floor slab into a multitude of pieces; all of which rain down upon the helpless bystanders below. Luna hears the explosion, and immediately does an about face towards the scattered rubble. Moving herself underneath one end of the falling debris, Luna releases a field of her own magic, which halts every last piece of the destroyed floor before anybody comes to harm. The ponies and Spike are relieved, but this reassurance was fleeting, as Twilight had contrived an opportune time for her to attack Luna head on. In a simple tactic, the draconicorn extended her arms straight outwards at Luna, grabbing her by the waist. Just as Luna noticed what Twilight had done, the draconicorn initiated her actual attack by relentlessly tickling the princess, causing her to laugh uncontrollably. Due to her loss of concentration, Luna's control began to enervate, and her hold on the multitudinous fragments of stone was fluctuating. No longer able to endure the onslaught of titillation, Luna—against her will—severed her grasp on the debris, thereby causing it to plummet to earth—and directly towards Princess Luna! Everything having gone perfectly, Twilight retracted her arms from the princess's body to elude personal injury. Because of the ongoing after effects of the tickle assault, Luna was unknowing of the coming danger, and before she knew what hit her, the princes was crushed by the falling rocks, and buried beneath a mound of rubble.
Sounds of gasps and low shrieks of horror emanated from the many corners of the throne room where Twilight's friends found themselves standing. Did their princess truly become flattened by the hailstorm of falling stones? It seemed nearly improbable, but there it was in front of each and every one of them...a sight which could not be unseen...a notion which could not be believed...
As the ponies and Spike struggled with the belief their princess had truly been defeated, Twilight walked casually over to the heap of what was once a supplement of the throne room floor. She waved her hand over the debris; her magic brushing away the rubble as if it was nothing more than a pile of dust. Twilight shifted her glaring orbs downwards at the lone victim of her sinister machination; her roguish smile indicative of her malapropos pleasure in her victory over the princess of the night. Luna's prostrate body lay unconscious before the draconicorn, her front side facing away from Twilight. She was covered from head to hoof with bruises; thankfully the princess' magic-infused resistance prevented her from sustaining any grievous injures—though exempt from trauma she was not. These visible contusions were the proof that Twilight's attrition had finally paid off—at least for her. Twilight enjoyed the games she played with the alicorn during the majority of their clash, but even she grows tired of messing with the same pony repeatedly, so it had been time for a winner to be chosen; and it was quite apparent only Twilight would be leaving this throne room the victor.
"This has certainly been a fun experience for me," Twilight said as she leaned her head down towards Princess Luna. "And you were quite the resolute one for having tried so hard to defeat me even though you never stood a chance. I must give you point for that: what do you say to a 6 out of 10?" Luna did not show any form of a response. "Okay! Okay! 7 out of 10! You're rather insistent, aren't you? I guess that's just another one of your actually salvageable qualities," Twilight chuckled over the still body of the princess, whilst all others in the room watched with a searing rage—especially one pony in particular.
Celestia had finally managed to get back up on her hooves. Her eyesight was still impaired to a certain degree, but she could see well enough to make out the form of Twilight snickering at the defeat of Luna at the hands of the draconicorn—and as one would expect, Celestia was none too happy. Even though she knew it was Twilight underneath that villainous exterior, Celestia would not hold back against an attack from anypony on her own sister. So, without hesitation, Celestia charged what power she had and fired off a single blast straight at Twilight. However, even though fueled by the fury of the princess, her power was still no match for the unstoppable draconicorn, who simply turned the top half of her body around and smacked the blast back at Celestia with one swing of her hand. Celestia attempted to dodge though use of flight, but the blast reached the princess and blew her against the back wall behind her throne, with the princess collapsing down to the floor in a stunned daze.
"You see there?" Twilight pointed at Celestia while the rest of the people present in the throne room were dumbfounded by Celestia's expeditious defeat. "That's what happens when you try: you just make a fool of yourself; though it's obviously too late for you to avoid that mistake, isn't it?" Twilight chuckled a smidge. "But I guess I can't blame you; I can sense when and where any magic user utilizes their powers, so if you want to try getting the drop on me, try doing something a little less magic-y," she says as she leans her head in towards Luna, her voice as complacent as her grin.
With a strike as fast as lightning, Princess Luna(whose comatose state was merely a ruse) reared her hind legs and bucked Twilight squarely under her jaw with a bone-rattling clout. The draconicorn went flying up through the air, first crashing onto the floor with the crown of her skull, then jouncing off the floor like a rubberized ball and landing on her feet. She whirled around in a daze several times, mutters "Yep; that'll do it," and ultimately collapses to the floor of the throne room in a state of genuine unconsciousness.
Luna staggered into an upright position, and turned to face her fallen adversary. "It seems that you are no longer the maker of fools here, creature! And you shall be so no longer!" On that note, Luna rose into the air, and swiftly made a beeline for Twilight, fully set on raining her vengeance upon the insensible draconicorn.
"Luna, wait!!" Luna halted in mid-flight, her passage blocked by the sudden advent of Twilight's friends; all of whom voicing their own pleas for the princess to heed their words.
"Don't hurt her!"
"She hasn't done anything wrong! Wait, she actually has—but don't hurt her anyway!"
"What are these nonsensical words you ponies speak? And why do you intervene on my responsibility to end this monster's reign of terror?"
"This isn't a monster! It's Twilight!"
"She's just been cursed!"
"Curse? What curse?"
"A curse of the most heinous kind," everyone looks to see Princess Celestia limping towards them.
"Sister!" Luna exclaims as she flies to her sister's side, fretting wildly about the condition of her sibling.
"You need not worry over me, Luna. I have not sustained any serious injuries," Celestia explains before cringing from the pain in her foreleg; almost falling to the ground until Luna catches her and assists her sister into standing upright again.
"This most certainly merits worry, Celestia! We must send medical aid for you at once!" But before Luna can perform said action, she is stopped by Celestia's further vocalizing.
"We have no time for that. We must first perform aid for Twilight," Celestia motioned towards the still unconscious draconicorn, and Luna was shocked to see Celestia also proclaim the creature to be Twilight Sparkle.
After several moments of contemplation, Luna inquires as to how Twilight had become this horrid monstrosity. Celestia has the other ponies and Spike gather around Princess Luna, so they may elucidate the recent goings-on to the unaware princess.
