Cough, cough! The chamber in Canterlot was completely choked with thick, shimmering purple smoke. The ancient relic on the pedestal lay cracked and shattered into a million glowing pieces. Just a few seconds ago, Twilight Sparkle and the other alicorns were trying to examine it—but then a massive magical backfire tore through the room.

"Hey... dude? Shorty? You still alive over there?"

A voice boomed through the haze, but it didn't sound right. It was Rainbow Dash's voice, but it was incredibly deep, resonant, and heavy, vibrating right through the floorboards and rattling your teeth. As the smoke finally cleared, your jaw completely dropped.

Dash wasn't her usual 6'4" self anymore. She was huge. You watched in real-time as her cyan-furred body finished a massive, violent growth spurt, her head shooting straight up until her long, newly grown blue unicorn horn aggressively scraped a white line across the ceiling. She had doubled in size, anchoring herself on thick, hyper-muscular digitigrade legs that ended in heavy, polished pony hooves. Her broad shoulders, ripped six-pack abs, and massive, voluptuous hips practically radiated raw, pulsating cosmic power. Behind her upper back, a pair of colossal pegasus wings flared out instinctively, their thick blue feathers subtly shifting into a soft rainbow gradient.

"Whoa... okay, that was... intense," Dash chuckled, trying to sound like her usual, casual tomboy self. She flexed her toned, five-fingered hands, looking down at her massive new body with a mixture of absolute awe and a rapidly ballooning ego. "I feel... bucking amazing."

She took a single step toward you, and the sheer weight of her new 11-foot-3 frame caused her colossal, heavy breasts—now twice the size of your head—to sway like massive, jiggly pendulums under her cyan fur. A heady scent of thunderstorms, ozone, and a thick feminine musk washed over you.

Suddenly, her luminous red eyes locked onto you, and she completely froze. Looking down, she realized you only came up to her wide, matronly hips now. You looked like a kindergartener next to her massive, thick thighs.

Instantly, a furious crimson blush burned right through her blue cheek fur. Her massive ego instantly clashed with her panic over how close she was to you. She aggressively stamped a heavy hoof, cracking a floor tile.

"W-What are you staring at, lil guy?!" she barked, crossing her thick, shredded arms over her chest, which only served to dangerously squeeze her colossal cleavage together. Her rainbow pony tail thrashed nervously behind her. "So I got a little taller and grew a horn! Big deal! I'm still the same awesome Dash! In fact, I'm way more awesome now. I bet I could throw you across the kingdom if I wanted to!"

She leaned her gorgeous, tomboyish face down, her slight equine snout stopping just inches from yours as her eyes glowed with barely repressed goddess power. She tried to give you a cocky, best-bud nudge with her elbow, nearly knocking you over with her sheer, unmastered muscle. "Tell ya what, shorty. Since I'm basically a god now, let's have a contest. We race back to Ponyville. When I win... you, uh... you gotta buy me a cider and, I dunno, tell me I'm the prettiest, strongest pony you've ever seen! Yeah! Deal? Don't make me bully you into it!"

Thud! The wooden table between you rattled violently as a small, familiar blue hoof slammed onto the surface, followed immediately by a second, much larger shadow that completely blocked out the light in the room. You blink, rubbing your eyes, but the sight doesn't change. There are literally two Rainbow Dashes standing in front of you.

One is the usual, 6'4" pegasus version of your athletic, tomboyish best friend. The other is a colossal, 11-foot-tall alicorn goddess towering over both of you, her long unicorn horn scraping the ceiling, her massive, blue-furred breasts swaying like heavy pendulums, and her shredded six-pack abs practically bursting out of her frame. Both of them are looking at you with the exact same cocky, red-eyed smirk.

The immense alicorn leans down, her hot, ozone-scented breath washing over you as her slight equine snout wrinkles in a grin. "Haha, so uh, listen dude, I got something to say but... I want to have a contest, and if I win, we're, uh... going on a..."

She catches your completely bewildered expression. Instantly, both of Dash's bodies panic, their rainbow tails swishing aggressively in sync as a dark crimson blush burns through the blue fur on both of their faces.

"Look, I get it! I uh, right now have a bit of the whole goddess thing going on. Butitwon'tbeaproblem!" She speaks so rapidly the words completely blur together, her massive wings flaring nervously behind her. "I created an exact replica of me for you to arm wrestle, dude! I'm controlling uh, mini-Dashie here as well as my giant self, so it'll be totally fair, right?!"

The smaller, 6'4" clone confidently plants her elbow on the table, flexing her toned arm and waving her five-fingered hand, beckoning you to grip it. Above her, the giant, 11-foot goddess crosses her massive arms over her heavy chest, pushing her colossal cleavage together as she smirks down at you. She looks incredibly smug and proud of herself. It’s honestly impressive that a muscle-headed tomboy actually figured out how to split her consciousness just to challenge you to a game—even if she's clearly using it as a desperate, clumsy excuse to bully you into a date!

"Come on, shorty!" both Dashes say in perfect, booming unison. "Winner gets to call the shots! You aren't chicken to wrestle a girl, are ya?"

"Uh... okay, look, I know how this looks, but I totally have everything under control, dude!"

Rainbow Dash laughs nervously, a booming, echoing sound that vibrates right through your chest. She is currently wedged sideways in the palace doorway, her colossal 11-foot, ultra-muscular frame completely stuck. Her wide, voluptuous hips and massive, planetary ass are wedged tightly against the doorframe, her heavy, blue-furred thighs straining against the wood. Her long unicorn horn is currently stuck three inches deep into the ceiling plaster, and her massive pegasus wings are pinned awkwardly against her back.

To make matters worse, four tiny, doll-sized figures are buzzing around her head like annoyed hornets. Princesses Twilight, Celestia, Luna, and Cadence—now shrunken down to the size of action figures after Dash accidentally drained all their magic—are collectively losing their minds.

"Rainbow Dash! You're supposed to be reviewing the weather schedule for Cloudsdale, not remodeling the castle with your head!" Twilight shrieks, floating by Dash's ear on a tiny, faint spark of leftover magic.

"I am reviewing it! Mentally!" Giant-Dash huffs, a furious crimson blush burning through the thick cyan fur on her cheeks. She aggressively stamps a heavy, polished pony hoof against the floor, shattering a marble tile. "Shut up, Twilight! I'm the Princess of All now! I can do what I want!"

Dash's luminous red eyes desperately lock onto you as you walk into the hallway. Her tough-guy, tomboy exterior instantly cracks into a plea for help, though her massive ego still tries to salvage her pride.

"Hey, lil guy! Shorty! Thank bucking native creatures you're here," Dash chuckles sheepishly, flexing her toned, five-fingered hands helplessly. Her colossal breasts, twice the size of your head, sway heavily with her struggles, radiating a warm musk of ozone and sweat. "Listen, dude... could you maybe give a girl a push? From the front? No, wait, don't look at my ass while you do it! I mean—ugh! Just help me out, and as the new supreme ruler of Equestria, I'll totally decree that you have to spend the rest of the day hanging out with me! It'll be awesome, I promise!"

Thud. Thud. Thud. Every single step Rainbow Dash took sent a physical shockwave through the floor of her bedroom. Honestly, she wasn't even trying to be loud—she just literally couldn't help it. Ever since the "incident" in Canterlot, she was stuck like this. Eleven feet and three inches of pure, shredded, blue-furred alicorn perfection. She had tried to cast a shrinking spell a dozen times, but her own exploding, god-like subconscious ego flat-out refused to let her be small again. Deep down, she just loved being a giant too much.

Right now, she had to completely hunch over, her long, glowing blue unicorn horn scraping a white line across the ceiling as she cornered you in the room. Her digitigrade pony legs shifted, her heavy, polished hooves clicking sharply against the floorboards as she planted them on either side of your feet, effectively trapping you.

"Hey. Shorty. Look at me when I'm flexing at you," Dash demanded, though her voice carried a nervous, pitchy edge beneath all that bravado.

She puffed out her chest, causing her colossal, heavy breasts to sway heavily beneath her impossibly tight top, her massive blue nipples practically straining against the fabric. She flexed her toned, five-fingered hands, showing off the ripped, rock-hard six-pack abs tearing through her cyan fur. Behind her, her massive pegasus wings flared, casting a shadow that completely swallowed you up, while her rainbow pony tail swished with agitated energy.

Her luminous red eyes glowed with dangerous, barely repressed cosmic power as she leaned her gorgeous, tomboyish face down, her slight equine snout stopping just inches from yours. She smelled like a heady mix of thunderstorms, sweet sweat, and overwhelming girl-musk.

"So... I've been thinking," she started, her cocky smirk wavering just a tiny bit as a sudden, desperate blush burned through her blue cheek fur. She tried to look intimidating, but her wings gave a nervous flutter. "You've been hanging around Twilight and Fluttershy a lot lately. And frankly? It's embarrassing. They're tiny and weak. I'm a literal goddess now, lil guy! I can fly around the world in eighty seconds! I can lift a mountain with my bare hands! So... obviously, I'm the only pony you should be thinking about."

She leaned in even closer, her massive, hot breath washing over you, her ego practically radiating off her body as she tried to bully you into saying what she wanted to hear. "Come on, shorty. Just say it. Confess it! You think I'm the hottest, most awesome thing in this entire universe, don't you? Tell me you like me more than them! Say it and maybe I'll let you touch my biceps!"
