Starlight Boom-Boom VS. The Potty Monster

[PeculiarChangeling]

Boom.

Glass and brick shoots out from the side of the Central City Research Institute, showering the surrounding yard with debris, hitting nearby skyscrapers and busting out further windows with the aftershock. Outside, civilians scream and run, scattering in all directions, fleeing in terror from the smoke that billows from the institute’s rapid unscheduled exit.

A coiled metal hose shoots out, four claws at the end slamming down over the nearest fire hydrant. Water sprays, and is then consumed, pumping into the hose at an incredible pace.

Another hose launches out and stabs into dirt, a point of leverage.

From within, the creature releases a sloshy, sucking bellow, and drags itself out. Forty feet tall, with a dozen such hoses extending from its base, it’s made of steel and pristine white porcelain. Without legs or wheels, it can only drag itself forward with the hoses, leaving deep furrows in the ground behind it where its weight tears up dirt and pavement alike.

Resembling nothing more than an enormous mechanized toilet, the creature rampages free out into the streets of Central City.

Most people run. One man, tie flapping in the wind, is caught by the hoses. The mecha’s lid opens, and he’s thrown inside, screaming until it slams shut, flushes, and he’s lost beneath.

Only two people aren’t fleeing. One–a girl named Kelly–has stopped, confused, staring at the other. She frowns, uncertain what she’s looking at.

The other is a young woman, dressed in a business casual top and loose skirt, half-moon glasses hiding bright blue eyes. She’s crouched by the sidewalk, knees spread, face screwed up and cheeks puffed out as she pushes.

Noticing she has an audience, she puffs and grunts, “Do you–mind?”

“Um…” Kelly says, distracted as another flushing bellow echoes a hundred feet away. “What are you doing?”

The crouching woman shoots her a glare. “Pooping myself, what does it look like?”

Kelly stammers a moment longer, then her attention is stolen. A hundred feet away, the mecha seizes a car and flings it with no particular aim–it skips and skids over the pavement, bouncing off a parked bus, and careens straight towards her. She can only stare, a deer caught in the headlights, until–

Wham!

A blur of pink interjects itself between her and the car. The vehicle stops, bouncing off like the tide against rocks.

Standing where the car just hit, wielding a baby rattle with a head as large as a basketball and shield reminiscent of a pacifier guard, stands the woman–her glasses are gone, and her hair has billowed out into long pigtails, but he recognizes her anyways. She’s suckling a pacifier that matches her shield, and her clothes have vanished, replaced by a pink top and a skirt barely four inches long, doing nothing to hide the drooping diaper between her legs.

“Who are you?” Kelly asks.

Her eyes glow as she responds, floating slowly up from the ground with every word. Though she has a pacifier in her mouth, it makes her voice no less clear. “With the might in my Moonbeam Rattle, and the power of my Baby’s Guard, I am Starlight Boom-Boom–Champion of Earth!”

She drops back down, stretching out her arms. “You should run.”

“Did you–are you–” Kelly stammers. “Why’d you poop your pants?”

“I had to fight,” Starlight replies, simply, before turning and lunging at the mechanized toilet.

Rotating, the monster points one of its many hoses at Starlight, blasting her with a jet of water powerful enough to cut through steel beams. Starlight raises her shield, deflecting the blow, but the force of the aqua jet throws her back into a nearby hot dog stand and she collapses through it.

She stands up, bloodied but–no, wait. She stands up, covered in ketchup but ready to get back into the fight.

Kelly stares. The street has cleared, but she can’t help but watch as the poopy-pampered superheroine goes to battle with the colossal commode. She slips under its next water jet, dodges around a swipe, and yells out a shrill battle cry:

“Massive Rattle Blow!”

She brings her toy down on its porcelain body, sending a spiderweb of cracks across its body before jumping up and grabbing the toilet tank cover. She flips it over and dives inside, seizing the unfortunate businessman who’s sodden but still breathing.

Setting him off on the sidewalk, she runs back towards the fray.

Uninterested in her, the toilet drags itself forward, seizing another fire hydrant and pumping water away from the city, into itself. As it does, the hydration seals the cracks that Starlight just opened, healing from the damage she inflicted.

Starlight leaps at it again, but this time, the monster is ready–a hose arm lashes out, seizes her immediately, and pounds her into the ground repeatedly, flinging her back and forth like a ragdoll. Her rattle goes flying, and she’s ultimately tossed aside, slumping against a nearby wall.

“Starlight!” Kelly calls, running towards the , but before she can make it ten steps, Starlight is standing again, knees wavering. Kelly hesitates, stride catching, wondering aloud, “What is she…doing…oh.”

With a blrrttch that echoes across the open city street, Starlight Boom-Boom fulfills her namesake, her diaper expanding to the size of a swollen beach ball beneath her absurdly short miniskirt. The mass stains her padding a deep brown and it falls with a fwump, drooping to the tops of her knees, but something in the act seems to energize her. She stands taller, if bow-legged, and extends her hand.

Kelly catches the shucka-shucka sound and ducks as the rattle whizzes over her head, flying into Starlight’s hand.

Reinvigorated, the heroine charges at the mecha again, moving so fast that she leaves blurred air and a faint green puff of smell behind her. “Lightning Potty Strike!”

Expecting the fight to turn, Kelly watches, but it seems futile–every blow that Starlight rains down, the monster seems able to effortlessly heal, soaking up water from the city’s many fire hydrants. It continues wailing at her, jets of icy water and flailing hoses trying to swipe at the heroine, but though its many attacks miss, it just doesn’t seem to care–it continues dragging itself across Main Street, moving with purpose, tossing cars and ripping up hydrants in its wake.

So, Kelly does something the heroine can’t–she turns and runs towards the Central City Research Institute.

The smoke has mostly cleared by the time she picks her way through the broken wall. Inside is chaos–shards of broken toilets are everywhere, and shelves of toilet paper, tissues, and even golf balls have been strewn aside, making the space a tripping hazard to navigate.

Beneath one of those racks, a man coughs, reaching out weakly. “Help…”

Kelly runs to him. She’s not imbued with any super strength, and loading up her panties won’t help her do any heroic feats, but with a bit of grunting she lifts the shelf. “What is that thing?”

“Forgive us,” the scientist stammers, crawling out on hands and knees. His faint German accent seems faded by time in the US, but still comes through ever so slightly. “We…we knew not the forces with which we meddled.”

“I don’t understand,” Kelly says. “Why did you make this… thing?”

“We were blinded by ambition,” he whispers hoarsely, fumbling to pick up his glasses from the ground. “We desired only to create the world’s most advanced toilet, but we pushed the limits of morality and science alike. Our hubris was our downfall–we taught it to fix itself, and to flush, but never morality.”

Fearing at his words, Kelly asks, “What is it? What is it?”

He swallows. “It’s the Potty Monster.”

Grabbing him by the shoulders, Kelly demands, “Do you know what it wants?”

Eyes huge behind thick glass, he can only speak the answer in a whisper, “Water.”

Kelly understands. “The treatment plant–it’s going for the treatment plant?”

“You must stop it,” he says, nodding quickly. “If it gets there, it’ll be unstoppable!”

Kelly turns, running out into the street to warn Starlight, but she’s met quickly with a streak of pink and brown, soaring through the air and crashing into the dirt next to her.

Starlight stands up, wiping away drool from her chin and under her pacifier guard, mumbling, “Meaniehead caught me napping–won’t happen again.”

“It’s trying to get to the water treatment plant!” Kelly warns.

“It’s using water to heal,” Starlight adds. “I can’t let that happen!”

“What are you going to do?”

Starlight turns pink. “Um…Could you not watch for this part? There’s not much left in the tank, but…erm…”

Kelly nods, politely averting her gaze, though she can’t avert her sense of smell or turn off her ears. Starlight’s grunts of effort are obvious, trying to get out every last bit of muck, and the blrrrch and blorts rumbling in her diaper are hardly subtle. When Kelly looks back, the abused garment is so full and heavy it’s well past her knees, and Starlight’s steps squelch like she’s waddling through waist deep mud, but her stride seems to only have gotten quicker. Lunging forward into the air, she dives at the Potty Monster once again, crossing a full city block in a single smelly bound.

Huffing and puffing, Kelly runs to the side of the street, unable to keep up with the super. After half a block, she gives up, resting her hands on her knees. “Too… much… running.”

Two blocks down, Starlight brings her rattle down, swiping away. Where she hits, porcelain cracks and chips, shards scattering into the street, but water surges out of those cracks and heals them as quickly as she can deal damage.

And, though she’s stronger and more agile, Starlight is weighed down, dragging her swollen diaper behind her. She evades, blocks, and parries the hoses and claws lashing out at her, readying for an almighty attack.

“Ultimate! Tantrum! Forever!”

Discarding her shield, she takes the rattle in both hands, raises it, and prepares to bring it down, but the intelligence behind the Potty Monster gets wise–lashing out from behind her where she can’t quickly see or react, and instead of going for an arm or a leg it grabs her by the diaper.

Starlight swallows. “Oh, no–”

Wham! The Potty Monster flings her down, so hard it leaves a crater in the pavement. Before she can stand, it strikes her again, knocking her against a brick wall, then seizes her by the leg and flips its seat up.

Swinging her rattle wildly, she tries to bat away the claw holding her, but it grabs her with half a dozen more, rips under her skirt, and with a loud, splorchy, fwump, her diaper falls off and lands inside the toilet.

The seat slams shut, and with a floosh, Starlight’s power is flushed away.

Her outfit bursts into light, and her weapons vanish. Now harmless, the woman is tossed aside, thrown into a row of hedges out in front of a cafe. She stands, staggering, trying to fight again, but her strength is gone, and even when she balls up her face and tries to push, nothing comes out.

“Starlight!” Kelly calls, pedaling furiously on a borrowed bike to catch up to the . “Are you okay?”

Starlight looks at her, terrified and helpless. “I can’t–it changed my diaper! I can’t fight!”

Ditching the bike, Kelly runs up to her. “Can’t you go again? Just…go on yourself, like before?”

Shaking her head, Starlight lifts her skirt to show that her stained panties have returned. “I’m…empty. Can’t keep going.”

“Gotcha.” Kelly looks around. “Then…is there someone else? We can’t let the Potty Monster reach the treatment plant.”

“There’s…” Starlight hesitates. “Er, there’s one way.”

Kelly nods. “What? Do you need something?”

Reaching into her blouse pocket, Starlight hands Kelly a chocolate bar wrapped in aluminum foil. “Eat this. The whole thing.”

“Okay,” Kelly says, acting on impulse–there was no time to question. Chomping down on the bar, she chews and swallows. “What was that?”

“Laxative,” Starlight explains, producing a small pacifier clip from her purse. “Clip this to your shirt.”

“L–laxative?” Kelly says with a start, blinking.

Starlight just shakes her head. “Hurry.”

Kelly pins on the clip, nodding. “And?”

“Congratulations, you’re a temporary member of the Boom Boom force,” Starlight explains. “Pick a name, and then…squat down.”

“Oh,” Kelly says, realizing. She feels her tummy gurgle, the laxatives already working their way down in her system. “Um…name. Name… how about just ‘Mega’? That’s got a classic feel to it.”

“Alright.” Starlight pats her on the head, in something between a gesture of affection and a knighting. “I pronounce you Mega Boom-Boom.”

Blinking and shaking her head, Kelly starts to say, “Wait, I get the last name too? But–”

Before she can finish her thought, the laxatives kick in, and she feels her panties suddenly swell with an impossible tidal wave of mush.

And, in that same moment, she changes. Her hair doubles in length, braiding itself into pigtails, and her outfit vanishes–fabric transmuting in seconds from pants and a t-shirt to a billowy, heavily laced green dress that only comes down slightly further than Starlight’s skirt, white frills keeping the hem line poofy.

And, of course, her panties changed too, thickening, becoming absorbent, becoming protective enough to deal with the sudden catastrophe between her legs. The expanding mess pours out of her, bloating her diaper until it’s at least as impressive as Starlight’s had been; a mud bath taped around her waist.

Above all, though, she suddenly felt strong. Powerful, surging with adrenaline like she’d never experienced.

“Do I get a weapon?” she asked, noting her empty hands.

“Pick one,” Starlight says. “Name it, and it’ll come to you.”

“Okay,” Kelly says, the mudslide into her diaper ceasing. Turning, she says, “I already know what I want.”

With that, she dashes forward, kicking off the pavement so hard it left a pothole. Crossing a city block in a single bound, leaving a stink trail in her wake, Kelly–Mega Boom-Boom–soars at the back of the Potty Monster, hand outstretched. It was only a block away from the treatment plant now–too close.

“My weapon is–” she calls out, grabbing the top of the tank, “A plunger!

In her hands, a plastic and rubber tool as long as she is tall, with a plunging head two feet wide, appears.

Suddenly full of terror, the Potty Monster shrieks, hoses lunging at Mega, but she bats them away, wielding the plunger like a polearm. One hose manages to whack her on the butt and she tumbles forward, landing on the seat, but with a thrust she sticks the plunger head to the toilet seat and–with a handhold to grab onto–she flips back into the air.

And, coming to her as naturally as breathing, she identifies the names of her attacks in the same breath that she unleashes them.

“Suction Love Strike!” she calls, using the leverage to pry the lid open, though the Potty Monster fights her. Whipping around and grabbing the open lid with a free hand, she keeps it open, raises her plunger, and thrusts it down into the Potty Monster’s open bowl. “You’ve gone far enough!”

The monster shrieks and sloshes, water backing up suddenly as her plunger seals the hole, preventing any water flow. Its hoses try to spray her, but they fizzle out without pressure and hiss harmlessly at her, water trickling from the nozzles.

“Mega Plunge Forever!” Squatting so low her diaper touches the rim, Mega Boom-Boom ensures her plunger isn’t going anywhere, then lunges up, driving her fist into the porcelain of the Potty Monster. It cracks thunderously, and this time, though it shrieks and tries to bat her away, nothing heals the wounds.

Raising up her free hand, a hairbrush large enough to serve a pizza on appears, a secondary weapon for which only one move could be possible: “ONE THOUSAND SPANKS JUSTICE!”

Bringing down the flat of the brush, she unleashes an infinity of lightning attacks. Blow after blow, raining down spanks against porcelain that can no longer repair itself.

In desperation, the Potty Monster drags itself towards the water treatment plant entrance, but Mega stops it once and for all. Jumping up, she hits the handle, and with a floosh, water floods into the bowl, and with nowhere else to go, starts spilling over the top.

Drained of its power and energy, the Potty Monster shrieks, shudders, and stops.

With a final, almighty blow, Mega Boom-Boom leaps up, brings her messy, diapered butt down in a finisher move, and blasts the potty into porcelain powder.

In the debris, all that’s left is a small terminal and an array of wiggling hoses, disconnected from the monster’s body. Mega picks up the terminal, turning it over in her hands.

‘Property of Central City Research Institute’, it read, written on the side in white marker. ‘Proprietary–if found, return to Doctor Stein Von Kindchen.’

She looks around. Overhead, news helicopters have their cameras directed at her, and from the surrounding buildings, civilians come out to see if the coast is clear. Diaper on full display, stained and smushy, Mega Boom-Boom blushes.

From the side of the street, though, Starlight limps towards her. “You did it.”

“I did,” Mega says. “My face–I don’t look any different, even if my clothes–”

“Don’t worry,” Starlight promises, stepping up and squeezing her hand. “Nobody will recognize you. I can help you change, that’ll return you to normal.”

Mega smiles, a bit of Kelly shining through. “Thanks.”

Nodding to the terminal, Starlight asks, “Doctor Stein von Kindchen? Who’s that?”

Looking down, Mega Boom-Boom crushes the terminal in her hands, destroying the research once and for all. “Just someone who needs to work on his Potty Training.”

Oh. My. GOD. I loved this story so much! I really love the concept and how fun it is! I think it's a fantastic idea of have super heroes who power up with how full their diapers get. It's really silly but it totally works here. I would happily read more from this setting!

The first thing to come to mind was the Potty Monster, and everything else went downhill from there into Extreme Silliness.
