Dive Ball Love Splash (Nessa Gyaradosgirl TF)

Water. Endless, glassy water.

Nessa floated on her back, arms stretched out, the sun glowing dimly above her in a hazy blue sky. No clouds. No birds. No land. No sounds but the soft lap of waves against her body and the gentle thud of her heartbeat in her ears.

"Okay... this is weird."

She shifted upright, treading water slowly, long limbs moving in calm, practiced strokes. Still no shoreline. No docks. No islands. Nothing. Just the gentle pulse of the ocean in all directions.

A chill crawled up her spine, not from the water—it was perfectly warm—but from the creeping sense that something wasn’t right.

“How… Did I even get here?”

Her brow furrowed as she tried to recall the last thing she remembered.

Flashback: Hulbury Gym

The sound of battle still echoed faintly in her mind—the clash of water, the cheer of the crowd, the glint of determination in her opponent’s eyes. A young trainer, maybe fifteen, with that unmistakable spark of greatness in him. He had challenged her with confidence, and he had earned every moment of that match.

She smiled even now thinking about it.

"You’ve got talent, kid." she had said, handing over the Water Badge, her pride still intact despite the loss.

But then, that weird moment afterward.

The kid had lingered, cheeks red, but eyes steady.
“Would you… like to join my Pokeharem?”

Nessa had blinked. "Your what?"

He had chuckled nervously, like it was half-joke, half-dare. She laughed it off, waving a hand. “Cute, but no thanks. I’ve got my own currents to ride.”

Still, he seemed unfazed. He just nodded and pulled out a Dive Ball.

"Then take this anyway," he’d said. “It suits you.”

She had accepted it with a shrug. A little strange, maybe, but trainers were a strange bunch. She’d clipped it to her belt and walked away toward the beach.

And that was when…

Present – Back in the water

Nessa shivered, not from cold, but from that fuzzy blank spot in her memory.

The Dive Ball.

She looked down at her hip—except it wasn’t there anymore. No belt. No Pokéballs. Just her swimsuit and the water.

She turned slowly in place, scanning the endless sea again.

"Okay," she muttered to herself with a breathless little laugh, "If this is what the inside of a Dive Ball looks like, then I’m definitely leaving a one-star review."

But there was no echo. No response.

Just the slow rise and fall of gentle waves.

She kicked lightly beneath the surface, but a strange sensation tugged at her ankle—like seaweed brushing her skin.

Nessa looked down quickly, half-expecting to see seaweed or a Tentacool brushing her leg. But the water below was clear. Too clear: No fish, no kelp. Just her own dark legs disappearing into the blue.

Yet the feeling—like something pulling at her calves—didn’t stop.

She frowned. “What the—?”

It was starting to burn, tingle, and stretch.

With a sharp breath, she reached down instinctively, running her hand along her thigh—and froze.

Her skin didn’t feel like skin.

It was rougher, almost textured, slick, like scales. Her fingers brushed over ridges that hadn’t been there before, and as she pressed harder, she realized:

“That’s not right.”

Her legs were pressed together, almost unnaturally. It was like something was gluing them, fusing them from thigh to ankle into one solid, shifting limb. Beneath her touch, she could feel them… extending.

Not just stuck, stretching.

Growing.

“W-what the heck!?”

She recoiled, panic rising, but then she caught a glimpse of her right hand.

Her fingers. The ones that touched her leg. They were changing too.

Webbing now traced between them. The nails had hardened into dark, pointed claws. Her knuckles ached like something beneath them was trying to push out, to reshape.

She held her hand up in front of her face, turning it over, watching in real-time as her joints lengthened, her skin hardened, the color darkening into deep navy blue.

“Oh no. No, no, no! What is this?!”

Her body, all of it, was changing beneath the surface. She could feel the weight shifting in her hips, the drag growing stronger. Her core twisted as something inside seemed to uncoil and stretch outward, like her spine was lengthening, vertebrae by vertebrae.

The pull at her legs was no longer a sensation from outside, it was coming from within, like her body had decided to grow downward, elongating into something new. Something massive.

She kicked in the water to stay afloat, but it was harder now, her lower half wasn’t kicking anymore. It was waving, like a tail. A thick, serpentine motion that wasn’t her doing, not entirely.

Her breaths came faster, chest rising and falling. Every breath brought with it a new sensation: a spine tingling beneath her shoulder blades, a strange fluttering at her ears, and her throat beginning to tighten.

“My body, what’s happening to my—?”

But she couldn’t finish the thought.

Because her voice was already starting to sound different.

Nessa’s chest heaved as the changes surged through her. Her breath hitched, her body no longer floating so much as coiling in the water, moving with heavy, sinuous force.

She tried to speak, but what came out wasn’t words.

“Grrrhhh…”

Her throat burned—like her voice had turned to smoke and gravel. She coughed, tried again, straining to say anything coherent.

“Wh…what… is… h-happening—?”

But the sound broke halfway, garbled and deep.

“Gyarrrhh—!”

Her own voice startled her.

That wasn’t human. That wasn’t her.

She clutched her arms tight to her chest, feeling the roughness of her skin, the firm ridges of scales now creeping past her abdomen, curling across her ribs, up her shoulders. Her muscles twitched, stretching, pulsing with foreign energy. It wasn’t just change, it was growth.

Her body was expanding.

Every breath made her feel bigger, heavier, as though the ocean was suddenly too small to contain her.

“Gyarrrr…ghhhhhh—!”

A deep growl shuddered from her throat again, and this time she didn’t even try to stop it.

That’s when she saw it.

Out in the shimmering distance, a boat.

Something that wasn’t ocean. Something real.

Her eyes locked onto it like a starving predator spotting prey. Without thinking, without deciding, she swam toward it, each movement sending a shockwave through the sea. Her massive tail, yes, it was a tail now, lashed behind her, propelling her forward in long, aggressive strokes.

With every meter she closed, the anger grew.

A roaring tide in her head.

Why was she angry? She didn’t know. But the feeling swelled like a storm, a fury she couldn’t reason with. She could feel her body swelling too, as if the emotion itself was feeding the transformation. Her spine cracked longer. Her shoulders widened. The sea churned behind her in her wake.

Her ears stretched, pulled into long, sharp fins that caught the wind as she broke the surface.

Her arms clawed through the waves, her hands no longer quite hands. She hissed, low and guttural. Her jaw ached as her teeth sharpened behind her lips.

The ship groaned beneath the pressure of her tail, wood straining, metal creaking.

Nessa loomed above it, monstrous and breathless, her body wrapped like a serpent’s noose. The water rippled with the tension of her coils, every muscle coiled tight, ready to crush.

And then… something cracked.

Not the ship.

Her.

Her eyes widened. She could feel it… her own strength, her impossible size, the hunger in her bones to sink it.

“W-What…?”

She pulled back suddenly, as if burned. Her tail loosened, slid away from the ship, splashing back into the sea with a thunderous wave. Her claws trembled in the air. She looked down at her hands, no, not hands anymore. Thick claws, sharp talons with webbing. Not what she wanted to see.

“What is this?! What am I?!”

Her voice was ragged, distorted… but still hers.

Still human.

Her heart raced as she looked down at her reflection in the rippling water. What looked back was her face, decorated by scales, with elongated finned ears and fins on the back of her head. Her shimmering blue-black scales glinted in the light. Her eyes glowed faintly, as if she was just broken out of a spell.

She looked up at the boat, just as empty as before. Except…  that's when she saw him.

The boy.

That same infuriatingly calm expression.

Hands in his pockets. A soft smile on his face. Not scared. Not even surprised.

Just… waiting.

“You’re awake,” he said warmly. “Good.”

Nessa’s eyes narrowed. “You.”

He nodded. “I hoped you'd still be in there.”

Her massive tail curled slowly behind her in the water, more from instinct than intent. She rose slightly above the ship, water running down her scales in rivulets.

Her voice rumbled. “What did you do to me?”

He tilted his head, like the question confused him.

“I didn’t do anything bad, Nessa,” he said gently, like talking to a friend in distress. “I gave you something beautiful. Something powerful. Something that fits.”

She blinked. “Fits? This doesn’t fit anything! I’m a Gym Leader, not—” she gestured to her massive, scaled form. “Not this!”

His eyes softened. “No. You’re more than a Gym Leader now.”

She reeled slightly.

More?

No…he was trying to twist it. Trying to—

“You feel it, don’t you?” he continued. “The strength. The presence. People won’t just respect you now—they’ll worship you. As the biggest and greatest gym leader the world has ever seen.”

Nessa’s mouth opened, but no words came.

Because… yes, she did feel strong. Unstoppable. When she moved, the sea moved with her. She could crush a boat without trying. That kind of power wasn’t just raw… it was divine,  and it felt scarily good.

He took a slow step closer on the deck.

“And look at you,” he said, voice low and smooth. “That tail, those fins, those scales~ You’ve never looked more beautiful and majestic in your life.”

She flushed. “Stop saying that.”

“Why?” he asked gently. “Because you don’t want it to be true?”

She flinched.

“…Because it’s not,” she said, but even she could hear the weakness in her voice.

“Then tell me it feels wrong,” he said, meeting her gaze. “Tell me that deep down, you don’t love how you feel. The way the sea bends around you. The way your body commands attention.”

She hesitated.

Her fins twitched.

“I…”

He stepped to the edge of the ship, smiling up at her. “You’re beautiful, Nessa. You were before. But now? You’re legendary. Like a living goddess of the ocean.”

She wanted to argue. She really did.

But instead, she found herself lowering slightly in the water, head tilted to the side, uncertain.

“…just because it's true…,” she muttered, but her voice was softer now, less sure. “…It doesn’t mean you’re right,”

He just smiled.

“And yet,” he said, “you don’t deny it.”

He didn’t move. He just kept looking up at her, like she was something rare. Precious.

“Nessa,” he said gently, “you really are beautiful.”

She opened her mouth, ready to snap at him, to say don’t flirt with me while I look like this, but the words caught in her throat.

Because… wasn’t it true?

Her form shimmered in the sun. Her sleek, scaled torso curved with both power and grace. Her hair, still long and flowing, had become threaded with thin aquatic fins, rippling softly in the breeze. Her eyes glowed faintly, not with rage, but with a feeling that she couldn't quite understand herself.

Her breath hitched, and she glanced away. “…I guess I don’t look bad.”

“I’d say you look flawless,” he said, stepping closer along the ship's edge. “Like someone sculpted you from ocean and power.”

She flushed visibly, even in her giant form.

“You don’t have to agree out loud,” he added with a wink, “but your face says plenty.”

She huffed through her nose. “…It’s still weird hearing it.”

“But true, right?”

“…Maybe.”

“And your strength,” he went on. “That tail could split a ship in two. That voice could silence entire stadiums. I bet there isn’t a single Pokémon alive who could match your raw power now.”

Nessa felt it, deep in her bones. The truth of that. Even as he said it, she could feel her muscles coil subtly beneath the water, every flick of her tail sending ripples out for dozens of feet. It wasn’t bragging. It was observation.

“…I didn’t ask for this strength,” she said.

“But you have it,” he replied, calm. “And you’re not afraid of it.”

She didn’t answer that.

Because she wasn’t.

He smiled softly. “And your presence, Nessa… just standing there. You’re unforgettable. People will talk about you the way they talk about legends. They’ll look at you and feel small. And they'll love it. You’ll be a star no matter where you go.”

Her fins twitched again. “…That one’s a little much.”

He shrugged playfully. “Not to me. I felt it the second I saw you.”

She looked away for a moment.

“…I guess I do… stand out,” she admitted.

“Understatement of the year,” he teased, “especially with that height of yours.”

That got a laugh out of her. A surprised, deep chuckle that rumbled across the water.

“Okay, that’s hard to argue.”

“You’re towering over this ship like it’s a toy,” he said. “You’re not just tall. You’re glorious.”

Another blush crept across her massive cheeks, impossible to hide.

Then his tone softened.

“Of course, I know all this because…” he placed a hand over his heart, “I take care of my Pokeharem girls.”

Nessa’s expression froze.

“…Excuse me?” she asked, uncertain. Yet with no bit of anger in her tone, just confusion.

He nodded. “It’s my job to know everything about them. What they need. What they deserve. What they love to hear… what makes them shine.”

She didn’t speak. Her mind was racing.

“Nessa,” he said gently. “You’re already one of them. You just haven’t said it out loud yet. Don’t you finally want to admit that you are one of my Pokeharem girls?”

“…I’m not—” she began, but even she didn’t believe her own words.

“A pokegirl,” he said, stepping forward. “One who wants to be part of my harem. One who craves my company, this purpose. You didn’t realize it, but you’ve been drifting toward this since the moment I handed you that Dive Ball. We both know that we both want this. Right?”

She stared at him, eyes wide. Her breath came slow and uneven.

And the terrifying part?

He was right.

She did want this. She didn’t understand why. Maybe it was how he looked at her. Maybe it was how complete she felt. Maybe it was the way his voice tied her together after she almost fell apart.

Maybe… he just understood her better than she ever had.

“…I’m…” she murmured, voice barely audible over the sea.

He waited, patient.

“…I’m one of your pokegirls,” she said at last.

Her head dipped low, cheeks warm, eyes shy.

“I’m in your harem,” she whispered. “I belong there.”

His smile lit up like sunlight on the water.

“There’s my good girl.”

And the moment he said it, everything settled.

The doubts faded. The conflict drained. She felt her massive body relax into the ocean, like it was no longer something alien, but finally hers.

…

“Now then,” he said, glancing at the horizon, “Why don’t you give that new body of yours a test run?”

She tilted her head.

“Think you can pull us?”

Nessa grinned, a proud, powerful grin. Her coils lifted around the ship once more, this time with no aggression, only confidence.

“Of course,” she said brightly. “Just hold on tight, Master.”

With a powerful twist of her tail, she surged forward, towing the ship like it weighed nothing.

The sea parted before her. The waves bent to her motion. She laughed…roared, even. Not an ounce of rage in her tone, but only joy.

She was Nessa.

The Gyarados Queen of the Ocean and the Hulbury Gymleader.

And, of course, his favorite Pokeharem girl in the world.
