I'm just going to say this now since I've gotten a few questions about this. I'm will most likely not do any romantic ships/pairings. It will probably be just platonic/sibling relationship with a hug here and there. Plus, most of the crew are way older than Melody, she was like... seven or eight when she joined.

Anyway hope you enjoy this chapter.

Couple years later...

Melody sat in the crow's nest, bored yet again. The girl was now in her preteens but she still hadn't been allowed to fight the Marines, who were currently on deck. She was able to fight other pirate crews, heck she even got some to ally with her father-figure. But still, she wanted to face the Marines soon. The wait for that battle had also given time for the girl to get change a little.

Most of her hair, except the fringes that framed her face, was tied in a low ponytail. The shirt she always wore when she was younger was now tied around her waist, showing that she was wearing a camisole underneath now. She looked at both of her hands and looked at the back of them. On her right hand, Meraqua's mark had magically grown proportionate with her age, probably from the magic. Her Whitebeard tattoo however had to be redone recently because of the body art's inability to grow with her.

It was wrapped in bandages again, preventing anyone from seeing it. She stretched her hands towards the sky when she felt something grab both her wrists. Melody looked upward to see a man wearing a Marine's Captain coat. Her face was of shock while the man's was opposite of that.

"Don't worry. We've heard rumors that Whitebeard had a young girl hostage. We've come to rescue you."

Melody was at first surprised to hear the Marines didn't suspect her as a pirate until she remembered her tattoo was covered up at the moment. Before she could react, the Captain threw the girl over his shoulders.

"Oi what are you doing?! Let me go!"

"Calm down we're getting you back home."

Melody was tempted to punch the lights out of the guy but didn't know if it was okay with Whitebeard to do so yet.

Meanwhile with the commanders, they had taken down most of the soldiers. Marco was blocking a Marine's sword as he taunted them.

"Those hits won't work on me-yoi! Just scram!"

"No way! We won't rest until the captain finishes the rescue mission."

"Rescue mission?"

The 1st Division stopped the next strike with his avian foot. Using the other foot, Marco slammed the soldier onto the ground. The Marine panicked when he saw the flaming talons etching closer to his neck.

"Explain-yoi."

"T-There's been reports that you're holding a y-young girl hostage."

"Young girl... IT CAN'T BE!"

The blonde man threw the man overboard with his feet as he flew up towards the crow's nest he saw Melody enter. He looked in but saw that it was empty. Then he heard a command of retreat, making the Marines jump ship.

"What the heck is going on?"

"THIS WHOLE ATTACK WAS A DISTRACTION! THEY GOT MELODY!"

"WHAT?!"

Everyone looked towards the ship and did indeed see the dark-blue hair of the girl as she was still being carried by the Marine captain.

"Let me go! I'm not a baby!"

"Miss please calm down. You must be in shock for being with them for so long."

"I am not in shock asshole!"

The Whitebeard Pirates grimaced at the sight. The young girl that had grown onto everyone was now in the hands of the enemy. They all knew Pops told her to hold back her powers but they never encountered a moment where she was actually caught, surprisingly.

Their thoughts stopped when they heard the sharp sound of metal. The people closest to the railing stepped back as they saw Whitebeard approaching, his bisento in hand.

"Pops we're sorry. We got distracted and she was captured."

Whitebeard scowled at the sight of his daughter struggling on her unaware captor's grasp. With his grip on his weapon growing, the captain yelled.

"MELODY! YOU HAVE THE OKAY NOW!"

Everyone on the Marine ship looked confused at what Whitebeard said, except Melody. She turned her head back towards the Moby Dick.

"IS IT ALRIGHT IF I GO ALL OUT ON THEM?!"

As the soldiers looked at the girl with confusion, Whitebeard wasn't the one to reply but most of pirate crew.

"GO AHEAD AND SINK THEM!"

"SHOW THEM WHAT YOU CAN DO!"

The Marine captain was trying to process what was going on when he suddenly hear a rush of water. He looked down to see Melody's leg covered in rushing water and lifting away from him.

"Water Dragon's Fin Strike!"

The girl kicked the Marine right in his guy, causing him to crash into a nearby mast. Melody safely landed with the water on her leg disappearing and transferring to her fists. She waited until some Marines rushed her before she began fighting. As she waited, the bandages on her left hand unraveled, soon showing the tattoo that made her a Whitebeard Pirate.

"S-she's a Whitebeard?!"

"Heck yeah I am. Name's Melody Halcyon! Now get ready for this! Water Dragon's Torrential Fist!"

Melody punched multiple soldiers with incredible knockbacks. She heard the click of gun safety and turned to see the Captain she kicked standing behind a line of Marines with rifles.

"I didn't realize you were a Whitebeard Pirate but I guess it doesn't make a difference, your still a child."

Melody stopped her attacks when she saw the soldiers get out of the range of fire that was soon to come. The water evaporated as she looked at the Captain with a smirk on her face.

"Hmph, you should never underestimate the power of the Whitebeard Pirates you dumbass Marines. I'm not holding back anymore."

"Artillery squad! Fire!"

The soldiers simultaneously pulled the trigger and bullets came heading towards the girl. Melody tuned out her crewmates' cries of danger as Magic seals appeared at both her feet. The bullets were feet away from her as rushing water from the soles of her feet pushed her up into the sky. The bullets imbedded themselves into the wall and railing while the Marines looked up at the flying Melody. The girl spread her arms out with magic seals appearing by the palms of her hands.

"High tide! Low tide! The dragon still can swim freely! Let the only thing you see be the end of it!"

The Commanders on the Moby Dick watched the girl say the incantation with grins on their faces. They saw Melody's excited face, knowing that the youth was having the time of her life. They watched through the past few years her training to get stronger through trial and error. The spell in progress even took her some time to master and this was the first time she was using it in combat.

Melody's arms became engulfed with water that extended far past the end of her arm. With both of her arms covered by long tendrils of rushing water, the girl swung both arms down.

"Water Dragon's Tail Strike!"

The streams of water came crashing onto the deck and knocked many of the people overboard. The Marine Captain managed to get his bearing as he saw the dark-blue haired girl fly over him and heading towards the water. The ranked officer leaned over the railing and called out to the men in the water.

"Men! Capture her! We don't know if she's a Devil Fruit user but use Seastone Cuffs anyway! That's an order!"

The swimming soldiers gave their commanding officer a salute as Melody broke the water's surface. Once her body was fully submerged, the preteen closed her eyes and concentrated.

'Water Cloak'

Melody's body was soon blending in with the ocean but she wasn't done just yet. A small magic seal glowed behind her back where her lungs were and smiled.

"Gills!"

Now Melody had the ability to breath underwater, making it easier for her to move around. She swam towards the bottom of the ship, where seastone was layered over the ship. Melody looked back to see many of the soldiers hurriedly looking for her before having to go back up for air. The girl had to hold back a laugh as she went back to work.

She grabbed a steady hold of the material and bit into the seastone layer. With each bite, she felt a bit more of her energy returning and didn't worry about that serious of an aftereffect due to the resistance she eventually developed. She could eat the amount of seastone in handcuffs with ease but more than that would give her a slight stomachache. Soon she stopped her consumption and now there was a large hole in the seastone for her to see the actual ship bottom.

Melody swam a couple feet away from the ship and took in a deep breath. She set her aim at the hole she created and fired.

"Water Dragon's Roar!"

The pirates watched from the Moby Dick as a large torrent of water burst from the bottom of the Marine ship's deck. Some laughed as they watched the Marines on the ship panic over their sinking vessel.

A minute later, a jet of water came crashing down on the middle on the Moby Dick. The water evaporated, revealing Melody she walked over to the railing to look at the destruction she caused. She looked towards Whitebeard with an tired laugh.

"Do you think that last part was a bit of an overkill, Papa?"

"Gurarara, perhaps, but you showed them what happens when you mess with our family. Good job Melody."

The girl heard footsteps and saw Haruta. The girls gave each other a high-five before the older girl whistled as she overlooked the destruction.

"That was a lot of attacks. How long have you wanted to do that?"

"Since the first couple battles with the Marines. But I'm kind of glad you guys had me wait on fighting them though. All the training I did really paid off!"

"So... how long do you think until they give you a bounty?"

Melody giggled at the question but shrugged her shoulders. She heard the crew calling for a celebration and many of them went to prepare. Melody proceeded to go to the sleeping quarters and found her book. She opened it and skimmed past until she found the next open page for her log.

I finally showed the Marines what I'm made of today. I bet I'll be in the news the next couple days too. I'm getting strong mama, and when I see you again I'll be stronger than nothing you've ever seen, just you wait. -Melody Halcyon

"Oi Melody where are you? You're the MVP of this party!"

"Coming!"

Melody closed the book and put it away before running back outside, ready to be with her pirate family.

In another part of the Grand Line, an all-fishman pirate crew were gathering around one of the men holding the latest newspaper.

"Since when did Whitebeard have a kid on his crew?"

"Can't believe she sunk a Marine ship. That's some feat."

"What are you all talking about?"

The crew turned back to see their captain, a whale-shark fishman named Jimbei. With his wooden sandals making sounds as he walked across the deck, Jimbei asked for the paper. He looked at the article reporting on the sinking of a Marine ship in a matter of minutes. He saw a picture of a dark-blue haired girl attacking with a fist of water on her left hand which had the Whitebeard tattoo on it and read the caption aloud.

"This young girl who goes by the name Melody Halcyon single-handedly took down an entire Marine ship. Not much is known about her origins but her epithet has been declared as the 'Sea Dragon Princess.'"

'Whitebeard... you just keep getting more and more unique family members don't you...'

Meanwhile in the Marine Headquarters on the island of Marineford, the fleet admiral Sengoku was looking at a bounty poster of Melody in his office. In a little fit, Sengoku balled up the poster and threw it towards the floor, only to have his pet goat pick it up and start eating it.

"Whitebeard, having this girl on your crew is going to make it very difficult when the time comes to fight you."

"ACE LOOK AT THIS!"

A young black-haired boy wearing a straw hat came running towards his older brother, Ace, with a dirty newspaper in hand. Ace, a boy with messy black hair and freckles turned around to see his brother.

"What is it, Luffy? Another stag beetle?"

Luffy shook his head as he held out the wrinkly article. The straw hat boy showed his freckled boy the article about Melody.

"She's around your age Ace! She must be super strong if she's already a pirate!"

"Keh, that means we'll have to train harder too so we can beat her when we're pirates."

"What's that about becoming pirates?"

Both boys turned when they saw a muscular elderly man wearing a Hawaiian shirt, scowling at them. The boys made a break for it as the older man told them they were going to be Marines while chasing after them. The newspaper was left behind, to be carried by the wind elsewhere.

In another part of the world, a News Coo, one of the newspaper delivery bird of that world, was dropping off the latest paper to an uninhabited island. The reason he did so was because on his route, he passed by the island and saw a sign saying "Drop Newspaper off here" with the money needed to buy year-long subscriptions. So the bird placed the paper on the beach and flew off, hoping whoever read it would enjoy the paper that day.

For awhile the newspaper sat on the beach as the waves continued to roar. Then from the water, two tendrils appeared out of it and touched the newspaper. A teal glow appeared on the paper before the tendrils grabbed the paper and brought it into the water. The paper continued to be dragged deeper into the water until being pulled into an underwater cave.

The tendrils were used like hands to open up the paper. When it stopped at an article about a certain dark-blue hair girl. There was silent for a minute before a giggle was heard.

'You've really made your mark on world haven't you Melody. You must be having fun with your new family.'

Looks like a certain someone knows that Melody has gained a reputation on the Grand Line. Anyway hope people liked this chapter. Thank you for the support so far in this story!
