Disclaimer: This story, the OC -main, secondary or otherwise- don't belong to be but to a dear friend of mine who decided not to share it here. So I took it upon myself to do it for her.
However as to not be accused of plagiarism, I still made a few changes so it was more in my style than in hers (but that's about all that'll be changed). If anything, think of it as a remake.

An Ocean Rescue

"Bruxish?" I repeated. "What do you know about this Pokemon?" I asked Rottom-Dex.

"Huh… Bruxish, the Gnash Teeth Pokemon." He answered, speaking at a fast pace. He had pulled up a picture of the multi coloured fish Pokemon and I thought it looked ugly. And vicious. A small information tag in the bottom left of the screen specified that Bruxish was Water and Psychic type. "It uses the protuberance on its head to unleash its psychic powers, confusing them. It can also stunts its prey with psychokinesis… Its fangs are powerful enough to break a Shellder's shell… It also grinds its teeth while using his psychic powers, emitting a powerful and disturbing noise all around that can give headache to those who are close enough."

This explained what my friends and the Kahuna were going through. As Lillie and I were still on board the ship, the noise hadn't reached us. Still, it'd not save us from the Wailmer who was readily trying to topple the boat, keeping on pushing it to the side.

"We have to stop this Bruxish from using its Psychic powers for a second." I told Lillie. "It's the only way to get our friends out of whatever is happening to them and to stop the Wailmer from crashing into the boat."

"But how?" she asked, hugging her beloved Snowy close to her chest.

"Easy," I said with a smirk. "Let's battle it! Gaïa, you ready my girl?" Of course she was, and she proved it by jumping down my shoulder to the railing of the ship. Fortunately for now, the Bruxish hadn't noticed us. "I'll deal with it, try and move Wailmer away." I didn't wait for Lillie to answer and pointed at the fish Pokemon.

"Use Magical Leaf!"I commanded my Snivy who obeyed on the spot and took a good aim at the fish in the water, moving her tail at top speed, leaves of purple pink appearing around her. She swiftly made a gesture with her tail towards her opponent, sending the projectiles in its direction. Unfortunately, due to refraction of water, none of the leaves hit the Bruxish but they all fade in the water. "Damn." I swore.

And I emitted an even worse swearword when I got pushed aside by a light brown shape. The four legged Pokemon used the railing as support and dropped into the water, hitting the weirdly coloured Pokemon on the head. It hissed, grinding its teeth once again. I couldn't hear it, but the Pokemon that had attacked winced and was now moaning of pain. I recognized it as a Lycanroc. However, unlike Gladion's, this one was white and light brown and walked on all four. A midday Lycanroc.

"Gaïa, we've got to help him! Gaïa?" I looked around but my Snivy was nowhere to be seen. I leaned over the railing and spotted her, gracefully swimming. She must have fallen when Lycanroc had made his move. I smirked. Even though she wasn't a water type Pokemon, her serpentine body was at ease in the sea. "That's my girl!" I greeted her.

"Jade!" I heard from down bellow. As the Lycanroc had successfully hit the Bruxish on its protuberance, it wasn't using its Psychic abilities anymore for now and my friends as well as the Kahuna were now coming. I saw the Lycanroc swimming away to Olivia who petted him on its head.

"The Bruxish is responsible for it!" I told her, pointing at the Wailmer who had calmed down to my, and Lillie's, relief.

"I know." she said. "And now we've attacked it, it's bound to retaliate. And not alone. So be ready!"

"We are ready!" Ash claimed, his Pikachu standing proud on his trainer's head.

"Hm.. Ash!" Lillie called, her soft voice hardly loud enough to be heard by our friends bellow. "Don't use electric move in water!"

"What?"

"Don't use your Pikachu's thunder moves." I yelled louder. "It could be dangerous for all of you!"

"So, what do we do?" Ash asked, sounding disappointed.

"You stay out of trouble!" Lana commanded in a strangely firm voice that didn't exactly sound like her usual tone of voice. "Jade, can you send me the Pokeball that's in my pants pocket?"

"Take mine too!" Mallow said.

"Sure thing…" I rushed towards the end of the boat where the blue haired girl had left her clothes, carelessly scattered on the deck. I wasn't pleased to obey her as a mere errand girl, but I knew when to lay my ego aside. And this was one of these moments. "Here it…!" I was saying dashing back to them. But the words I was saying jammed into my throat. When I left, there had been only one Bruxish. Now there were like… half a dozen of them.

"I didn't know they worked in school!" I exclaimed out loud.

"Neither did I!" Rotom-Dex answered excitedly, taking picture.

"Rotom! Now isn't the time!" My friends and the Kahuna were trying to keep them at bay but it was complicated. They were outnumbered: Pikachu couldn't use his powerful electric moves and was trying to fight them off with his Iron Tail move. Unfortunately, it wasn't that efficient, as Bruxish were in their element and quite swifter than the yellow Pokemon. I threw the Pokeball to their respective trainer who thanked me with a wave of their hands before throwing their device open, revealing a Popplio and a Steenee.

"Popplio, go to the Wailmer!" Lana commanded her Pokemon. The blue and white Pokemon swam to the stuck whale and he inhaled deeply underwater. Then, a huge bubble appeared, shielding the Wailmer from the Bruxish.

"Lana! What's the bubble about?" I asked her.

"Wailmer is too weak to swim on its own." she explained. "It'll help him stay afloat and shield him from Bruxish's Psychic abilities."

I didn't quite understand how a bubble would protect a Pokemon from psychic power, but now wasn't the time for such question and explanation. Somehow, it seemed to have worked as the Wailmer suddenly moved away from the boat, letting it get back to its original position. And sending me in the water down bellow as I was still leaning over the railing.

As I was swimming back to the surface, I was glad that I had removed my jacket and boots earlier. I still fiddled to check that my collar was in place. Its cool and comfortable touch sent a reassuring feeling throughout my veins. My hair, now wet and cold flapped onto my neck as I broke through the surface and took a welcomed gulp of air.

"Jade! Are you alright?!"

Lillie! She had managed not to fall as she had been holding tight onto the railing with Snowy. I felt relieved that she was safe. I didn't even know if the light blond haired girl could swim. I answered to her with a thumb up but focused back on the fight at hand.

Lana was making sure that Wailmer was getting away little by little, using her Popplio as a line of defence against the Bruxish who tried to attack the massive Pokemon. I had to admit that this Popplio of her hold his ground. And I could see the same was happening with Mallow's Steenee and, as was to be expected, Olivia's Lycanroc.

I resubmerged when a wave pulled me down. Unfortunately, when it happened, my eyes had been open, and I felt a painful stinging sensation. I screamed out and inhaled some water. I managed to re-emerge and coughed vigorously. But during that split second I had my eyes open in the water, I had noticed some Bruxish paying much too attention to Ash and Kiawe who couldn't defend themselves properly, even though Pikachu and Marie did make their best to prevent the Bruxish from approaching.

"Marie, keep protecting them, Gaïa! Use Tackle!" I commanded. I had also seen that Gaïa hadn't lost time swimming around but had taken advantage of having fallen to attack many of the Bruxish. And she was now dashing towards those attacking the boys. She smashed into the first one, sending it swirling away, to its surprise.

"Good! Now use Magical Leaf!" As she was in water, she'd not be troubled by the refraction and the leaves were bound to touch their targets. And they did! I was pleased to see cuts appear on the fish's body. I was much less so to see all of them turning their back on Ash and Kiawe and rush at Gaïa.

"Leap into the air!" I shout out my command. "And use Magical Leaf to make yourself a barrier!"

My Snivy gained momentum and jumped out of the water, much higher than I had thought she'd manage. She started spinning around, greenish purple and pink leaves appearing all around her and swirling around her white and green serpentine body, shielding her against the Bruxish Water Guns. Yet, I knew it wouldn't be enough. What could we do?

But it seemed I had been uselessly worrying. As I was trying to think of a way to get out of this, and defeat the Bruxish, Gaïa puffed out her chest as she was slowly falling back towards the water. She began to be engulfed in a glimmering blue light.

Her silhouette morphed and grew: her tail lengthened and sparked out two… no three leaved petals, two of them being on her back. With a shout, she extended her hand, throwing off the light to reveal her evolution as well as throw the rest of the magical leaves towards the Bruxish which swam back a bit when she landed on the water, somehow managed to do it in a graceful manner.

Only her green head surfaced and I could see that her neck was now surrounded with a two golden spiked collar. She looked amazing!

"VINE!" Gaïa screeched out, her voice louder but also higher pitched than when she was a Snivy. She flipped into the air, her tail wrapped around her body and the leaves on both her back and tip of her tail glowing green. A huge smile spread on my lips when I came to the realization that she was trying to use Leaf Blade.

She smacked the Bruxish hard when she fell on them, spewing ocean water everywhere. That would require some training until she mastered the move correctly, but it was a good start. Though, for now, it'd be best to stick to the moves she knew to the tip of her tail.

"Use Vine Whip!" From bellow her golden collar, vines of green and yellowish colours came out and spread in the water towards the ugly fish Pokemon, just like tentacles. They reached their target and proceeded to hit and hit them again, on the head and their protuberances in particular, stunning them.

And, out of sudden… The Bruxish emerged… As if they had been leaping out of the water. But against their will for, once they were out in the open air, they flipped around and then, rock boulder came out of the water and smashed the Pokemon, sending them away where they crashed back into the ocean.

"I wasn't sure it'd work!" The Kahuna exclaimed after a loud sigh. "I am glad it did! Lana! How is Wailmer?"

"It's doing fine!" She answered. She was already far away with her Popplio, looking so small in comparison with the Wailmer. "It took the potion alright. It's gonna be good now!"

"What a relief." Mallow said, her Steenee holding onto her trainer's shoulders.

"Kahuna! What did you do?" Ash asked.

"It looked like Rock Slide… But different." Sophocles said.

"It was indeed Rock Slide!" she confirmed. "But I asked Lycanroc to throw the rocks up from the sea floor instead of down."

"Everyone is doing alright down there?" A male voice asked, throwing a rope ladder at us. "Are you ready to get back on board?"

"Yes Professor!" We answered in unison. Though, I wasn't looking up at the professor, all my attention was on Gaïa and her new wonderful appearance. I couldn't help but squeal and embrace her tight. I included Marie in the embrace when she nudged at my shirt, but still, I was so pleased about Gaïa's evolution that it was all I cared about at this moment.

"You evolved, Gaïa! I am SO HAPPY!" I laughed. "If I had known it was going to happen soon, I'd have pushed your training some more."

"Servi..." she merely said, wrapping her body around my shoulders.

"Sorry girl," I commented, seizing the ladder in one hand and Marie in my second. "Lana! Catch!" I hollered to the blue haired girl who was already on board. In a swift gesture, I threw my Tympole to her, to Marie's delight who had a scream of joy as she rose up into the air and landed right into Lana's arms. "I fear you're much too big and heavy for me to carry you on my shoulder as I used to…" I said to Gaïa.

"Ser? Servine!" She hissed.

"Don't be like this…" I mumbled, as I was climbing up, the exercise needing much more effort as Gaïa didn't want to leave my shoulders. I was relieved when she jumped down and I rubbed my painful limbs. Gaïa didn't look any pleased though. "Look… It's awesome that you evolved… You're stronger, faster and you got to learn a new move. But it also means there will be some changes…"

Gaïa was still looking away, upset. I rubbed my wet – and messy I could feel and imagine – midnight hair. What could I do to lift my newly evolved Pokemon's spirit… My eyes fell on the bracelet I had gotten from Olivia. My hand travelled to my necklace… It was still here.

"Here!" I said, taking off the bracelet off my wrist and tying it around Gaïa's neck. "What do you say? You got a necklace on your own!"

Gaïa emitted a humph sort of noise, but I could see she was pleased.

"And once we arrive, we'll train that Leaf Blade move of yours! What do you say? It's going to be useful when we'll battle the Kahuna!. But for now, let's rest!" I said, crashing on one of the benches. I closed my eyes, faking sleeping so none would disturb me, when, in reality, my thoughts were on the Kahuna and how she had battled the Bruxish. She may be a bit clumsy, yet she knew how to fight with her Lycanroc! I had a difficult battle ahead and Gaïa's evolution would be useful indeed if I wanted to successfully complete this challenge.
