Chapter One

The Padded Shapes of Nightmare
By Scribe Feather
✶✶Chapter One✶✶

Valley weather was always interesting during this transitional period between spring and summer. For about a month, Ponyville would enjoy less rain and more sunshine as well as cool nights that were just above chilly. Schedules were not as busy during this time as well as ponies had yet to transition from the laid back spring days and dive head first into the hectic summer months. All around the feelings were calming and quiet.

Twilight had invited all her fellow princesses for a night on the town. It was so rare to get everypony together for a day of bonding and the purple pony was quick to leap on the opportunity. She even went as far as to schedule the entire day from sunrise to sunset, filling it with fun activities, seeing the sights of Ponyville, and above all else bonding with the other princesses.

Of course, the rest of the princesses didn’t quite follow the schedule that Twilight had planned out. The day had a late start as the other princesses rather enjoyed sleeping in. Twilight’s planned tour of the modern art museum had to be rescheduled for another day because the rest of them wanted to go bowling instead. Bird watching was replaced with some quiet sun bathing and ice cream. By the end of it all, their day turned out completely different than Twilight had initially planned.

But none of that mattered to Twilight. What mattered was that Cadance, Luna, and Celestia were all here to bond with. And the other three, even after apologizing for all the rescheduling Twilight talked about having to do, enjoyed the purple alicorn’s company immensely!

The group of princesses had just gotten out of dinner, a filling meal at the fanciest restaurant in town: La Plaque De Fantaisie. It was just barely evening when the four exited the elegant and deluxe. The oranges of the setting sun were just now being replaced with the purples and blues of night. The moon was just coming into view after spending the day drowned out by the sunlight.

“Such a beautiful night!” Cadance exclaimed as the pink alicorn took in a deep breath of the cool valley air.

“It was nice to step away from the big city,” Celestia added, bowing her head to some passersby who respectively bowed back as the group walked by.

“I agree. Ponyville’s such a peaceful town at night,” Luna added before looking up at the sky. “You can really see all the stars from out here,” she mused, scanning the beautiful night sky with a satisfied smile, “why, even the moon is...Is...” Her words trailed off into a worried silence, quickly grabbing the attention of the other princesses.

The other three looked to Princess Luna with concern before looking up in the direction she was looking. In a few seconds, their faces closely resembled hers. Looming above the group was the glow of the full moon, right where it usually was most nights. However, unlike most nights, covering the moon’s spotted face showed an ominous shadow of a mare’s head.

“Nightmare Moon?” Twilight quietly muttered to herself, confused as she glanced back down to Luna. The blue alicorn was just as puzzled as she was.

“Sister,” Celestia looked to Luna with worry, “what could this mean?”

“I don’t know,” Luna answered with dread, “but I have a sneaking suspicion that we’ll find out soon enough.”

“To the castle then!” Twilight exclaimed, leaping in front of the group to lead the way. “At the very least its natural magics will aid us!”

The others agreed, quickly dash off with Twilight. To save time, the group opted for a more direct route, cutting through the alleyways and thin paths between houses.

In their haste, they were all making great time until suddenly they lost their footing, all four of them, quickly crashing to the grassy ground. The fall left the princesses dazed for a moment or two as the world around them seemed to darken. Looming overhead gathered a star filled fog that quickly grew in size and strength. The princesses could just barely stand back up before the fog had fully encompassed the group.

The star filled fog twisted and bent in the air, moving with purpose as one large black mass. It continued gathering from parts unknown before balling up into a dense fog and dropping to the ground in front of the four princesses. The misty mass then quickly morphed from a shapeless blob into something almost ponylike. The group could only stand there in a ready stance as the form took shape.

A sinister and oddly familiar laugh echoed overhead as the fog took its final form. Materializing out of the stars stepped out a set of long, black hooves. After that came a body and then two piercing blue eyes that shined with a sinister glow. The remainder of the fog quickly took the form of a purple, star filled mane that flowed through the air like waves of water as well as a tall unicorn horn that sprouted proudly off the figure's head.

When the fog completely disappeared and the mass had finally taken form, it was revealed to be Nightmare Rarity, a sinister combination of Rarity and the mysterious, evil force that once corrupted Princess Luna. The malevolent villain grinned with sharp teeth as she continued to laugh maniacally.

“R-Rarity?” Twilight blinked in disbelief and shock, “what...what’s happened to you?” The rest of the princesses handled the reveal with varying levels of surprise, unsettlement, and anger.

“Oh young Twilight. I have been reborn. Reenergized. Revitalized!” Nightmare Rarity proudly held up her unicorn horn into the air as the appendage sparked with pent up energy. The air around the group felt charged like moments before a lightning storm. “I have never felt such power! I just couldn’t wait to show you all some new tricks I learned. It’s fortunate that I caught you all together in one place. It’d be such a hassle hunting you down one at a time.” Rarity stood with arrogant flair, regally holding her head up high into the air as her mane continued to flow behind her.

Luna leaned forward in an intimidating stance, ready to cast a spell the second Rarity’s hold on them lightened up. Despite being frozen where she stood, the blue alicorn was ready to pounce, ready to leap on and repel the evil that took over Rarity. Celestia followed her sister’s lead, scowling at the threat as her body tensed up with adrenaline.

“Now I can bring you all down in one fell swoop!” Nightmare Rarity’s grin grew as she held her unicorn up high into the air. An evil energy began to grow around it as the air sparked with charged bolts.

The energy took on a fiendish green color before turning white and then finally turning a sinister shade of blue. Once the spell had grown to its full power, Rarity swung her head towards the trapped princesses and flung the ball of light towards them. The ball jumped light lightening off her horn, separating into four pieces in a blink of an eye before stabbing the four alicorns in the forehead.

A sense of dread fell over the four ponies as they looked at each other with equally shocked expressions. The air around them buzzed with energy as a green glow grew around all four of them.

The spell’s effect came in waves, drastically altering the four princesses in short minutes. Twilight could feel no pain in such transformations and could only stand there petrified as she watched her fellow princesses follow the same fate.

First came the numbness as she began losing feeling in her extremities. Then her soft, lavender colored coat began to fade away. The hairs slowly turned white, melting into one another till they smoothed out into a soft plastic that encompassed her entire body. She could feel her bones being replaced with padding as her body began to flatten.

Looking around with what was left of her eyes, she could see the other princesses meeting the same circumstance. Celestia seemed to hold the most resistance to such magic, only managing to slow down the effects as she painfully strained against the changes. Where Cadance quickly turned into a diaper bearing her cutie mark, Celestia and Luna seemed to delay it for only a few moments as they spent some time as diaper/pony hybrids. But even that wasn’t enough and in the end they all fell under the magic force, falling to the ground as thick, crinkly diapers with only their cutie marks visible to differentiate them.

“Twilight Twilight Twilight,” Rarity tsked, carelessly floating the lavender diaper around, “just look at you now.” She waved the diaper around in the air a bit before floating it in close to give its soft padded core a prod with her hoof. “Princess of Friendship demoted to a diaper. Just like your precious princess pals.”

She smiled proudly at the work she had done. Four diapers laying open on the ground where princesses once pleaded. Her smile only widened as this reality full set in. She was unstoppable now.

“Oh I’m sure you’re all rather bummed about spending the rest of your lives as diapers,” Rarity laughed as she neatly folded each princess diaper and stacked them all into an orderly stack that floated in the air, “but don’t fret. My mind is just teeming with ideas and opportunity. We just need to find the right fit...And the right test subjects...”

And with that, Nightmare Rarity melted back into her ghostly from, disappearing into the night with the diapers in tow.
