Chapter One: The Blond in the Water

East Blue, One of the five seas of the world and the supposed weakest sea out of all of them, birthplace of the Legendary Pirate King, Gold Roger. This sea is home to many great pirates like Buggy the clown, the pirate Admiral Don Krieg and the fishman pirate Saw-nose Arlong, and at this moment we see a small boat drifting on the sea with a person in it and had a bored look on his face.

"I'm so bored~!" the man was about 6'1" with blond hair with bangs on each side of his face, he had three marks on each cheek and ocean blue eyes. He was wearing a large thick white and blue jacket with blue accents with the kanji for 'maelstrom' going down the back. The jacket was open showing that he was bare-chested with with a slightly larger athletic build with an impressive eight-pack and wore two necklaces around his neck, one with a green gem and the was a golden tomoe with a red swirl at the end. He also wore dark, loose pants tucked inside large black boots, and a red sash around his waist. Next to him was a bag that was full of wooden swords and weapons with different weights and colors and extra clothes.

"Man I wish something would happen! I'm getting sick of this waiting!" As if fate was listening to him a giant shadow blocked his light. He looked up to see a giant sea cow heading straight for him with two bumps on his head. His eyes almost popped out of his head as he quickly tried to row away.

"Me and my big mouth!"

A few minutes earlier:

Not that far away we see a slightly bigger ship that had green lines painted on it with four people eating on the deck with an assortment of food on it that had three people on it. The first one was a boy wearing a straw hat with black hair sticking out from under it with brown eyes and a scar under his left one with a bone sticking out of his mouth, he was wearing a red vest with blue shorts with a white trim and sandals on his feet. This was Monkey D. Luffy.

The second person was a slim, yet muscular, long-legged young man with blond hair and keeps his hair brushed over the left side of his face with an eyebrow that curled from the outer end. He wears a black, double-breasted suit with a tie and a long-sleeved, buttoned shirt that had blue stripes on it. He was Sanji, one of the newest crew members to Luffy and the cook of the ship.

The third person was a relatively thin man of average height with short, scruffy, hair, a scruffy beard, and a slight mustache. He has dark circles under his eyes, as though he lacks sleep. He wore an open gray jacket with a red sea-serpent design on each side with a green shirt underneath, gray pants matching with his jacket, a gray headband with blue stripes design, and two spherical earrings on each ear. This man was Gin. He decided to follow Luffy after he defeated his previous captain, Don Krieg, and was welcomed by both captain and cook.

The last guy wore a black shirt with a green coat and red headgear. He has plaid yellow shorts over unshaven legs and dark shoes and, like his partner, carries a sword. He was Yosaku, a friend of the pair and a bounty hunter from east blue. Currently we see him pointing his hand between him and Luffy and waving it in front of him in a 'no' type manner as he held Luffy's stretched arm that was just about to grab some food off his plate.

"What is he trying to say?" Luffy asked as he still tried to get the food.

"No clue." Sanji said as he lit his smoke and laid back and Gin just closed his eyes to take a nap before they got to land. As Yosaku choked a little Luffy chucked the food into his mouth as the two looked at him weirdly.

"It could use some flavoring." He said as he kept eating.

Yosaku swallowed the food in his mouth stared at Luffy. "I'm trying to say it's mine!"

"Oh really? Who decided that?"

"I did. I put it on my plate, it's mine. That's how it works!"

"Well I don't see your name on it anywhere?"

As the two argued a shadow swam underneath the the ship and back down again. Sanji heard a noise and and told them to be quite, as he looked over the edge he saw it coming back up.

"Something's beneath us." All of them, including Gin who opened one of his eyes, looked over and saw a shadow rising and the water start to bubble. "It's huge…"

As the object rose Yosaku was freaking out and Luffy just looked at it without a care in the world. As the water cleared a giant sea cow with a big round nose with a gold nose ring appeared. It had a cow-esque face and horns, green spots throughout his body which had a seal-like appearance and scales on it's under belly.

"Monster!" Yosaku shouted as he tried to run away only to find that he can't.

"A cow! It's humongous!" Luffy said with excitement in his voice.

"A cow? Swimming? It's more likely a hippo." Sanji exclaimed smoking his cigarette.

Gin looked at the beast with a raised eyebrow. "That's a sea beast."

"But, why is that thing here in east blue? This kind of creature should only be at the Grand Line!" Yosaku said as he looked at it with wide eyes. The beast looked at the ship with mild curiosity.

"Eh? What's it up to?" Luffy said with his head tilted. Yosaku looked between the food and the beast and said that it probably wants it, as he was saying to give it to the cow before it tosses the ship over Luffy punches it sending it back into the water.

"Don't touch my food!" Luffy exclaimed as he pointed at it.

"You did it! You're great Big Bro Luffy!" Yosaku says as the sea cow resurfaces more angry now. "Ah! He's gone berserk now!"

"You want another?" Luffy says as he pulls his arm back only to be kicked in the face by Sanji.

"Baka! Don't beat up hungry mortals! Maybe he can't find anything to eat 'coz of injury or something?" he then picks up a plate and hands it to him. "Isn't that so?"

"What compassion!"

"Go ahead. Feel free to have it." The sea cow looks at him and the plate at the same time. the opens his mouth to eat it when Sanji kicks him backwards. "Go to hell!"

"What are you doing! Where's the love?!" Yosaku yells.

"That thing was going to feed on me as well. Self defense." He stated as the sea cow rose once again this time to crush them and they're boat.

"Here he comes! He's gonna turn the ship over!" As Luffy prepares to punch it Sanji stops him tells him he will handle this one. He then runs up the mast of the ship and kicks the cow in the neck.

"Collier Shoot! (Neck Shoot)" He then sends the cow flying and jumps back down on deck and continues eating.

"Now! Let's continue with our meal!" Luffy says with a little excitement.

"That was a nice workout."

"These guys are crazy…" Yosaku says with a small sweatdrop on his head.

"You're telling me." A voice said as a hand could be seen on the edge of the boat as Yosaku screamed at it. Luffy, Sanji and Gin stood up prepared to fight as the person climbed aboard with a large sack over his shoulders and in his hands.

"Man, what a rush! Nothing like a giant sea cow being thrown right at you to get the blood moving." he said as he got the water out of his blue and white striped bucket hat. Luffy perked up at the voice as he heard it before.

"Naruto? Is that you?"

Naruto looked up to see Luffy with three other men and smiled at him. "Hey Luffy! Long time no see!" Luffy just grinned ear to ear at seeing him again in so long.

"Hey Luffy, you know this guy?" Sanji said as he and Gin relaxed a little at their new captain knowing who the guy was but still kept their eye on him.

"Yeah! Guys this is my big brother, Naruto. Say hi." Luffy said as the smile never left his face.

"BIG BROTHER?!" Sanji, Gin and Yosaku yelled shocked at the news.

"Yep, I hope my little bro hasn't caused you much trouble. Sorry if he did." Naruto said as he scratched the back of his head a little embarrassed by the awkward introduction. His shirt started to move a little which Gin noticed.

"Hey, you got something stuck in there?" They all look down to see the bundle move before a little fox head popped out of the top and yipped at them.

"Aww, that nothing. It's just Yuuki!" Naruto said as he let the kit jump out of his jacket and onto the deck. It had orange fur with white on it's paws and the tip of the tail, it was the size of about a fully grown cat and could easily run faster than one too.

"Aww, it's so cute~." Sanji said as he went to pick it up only for the fox to growl at him and try to bite his hand. "You mutt! That's it, your dinner tonight!"

"Don't you dare! Besides she doesn't like new people, you need her to trust you first." Naruto said with his hands in his pockets looking at his pet/friend trying to eat the cook.

"Wait it's a girl?" Yosaku asks with his head tilted.

"Yep! And she has a HUGE dislike for perverts and womanizers." Naruto noted as he saw her growl at Sanji he was looking at her ready to kill it and cook it.

"Well anyway Luffy, what are you doing here? Don't tell me this is your so called best crew that you got?"

"No this isn't, but I do have more but we kind'a have a problem with our navigator at the moment." Luffy said as he scratched his cheek while looking down. Naruto raised an eyebrow at this as he and Yosaku told him about Nami leaving them at the Baratie and going to an island where Arlong is located. When they were finished Naruto was a bit wide eyed at what they just said and asked them.

"Wait, does Nami have orange hair, brown eyes, is really beautiful and thinks of money all the time?"

"Why yes that does sound like Nami-swan, but how do you know her?" Sanji said as he looked at Naruto with his eyes narrowed at the beautiful comment.

"Well I met her ages ago on an island not far from where me and Luffy came from. She was having a little...trouble with her village, so I helped her out with what I could do back then and made a promise to her." Naruto said as he helped dry Yuuki off.

"What kind of promise?"

"Well~, I can't say. It's her place to tell you and i'm just keeping the promise I made to her, sooo….yeah." Naruto said as he fully unzipped his jacket and squeezed out the water out of it.

"Okay." Luffy said with a grin as he trusted his brother greatly. "But I want to get there quicker! Why can the stupid wind hurry up and blow." He screamed as Naruto had to sweatdrop at his little brother's behavior.

"I see my time away from you hasn't made you any more mature or smarter, has it?" Naruto questioned as Luffy ignored him and looked towards the sea and grinned a little.

"Hey guys." Luffy said as everyone looked towards Luffy who had a grin on his face. "I just had a great idea of how to get to land faster."

Naruto knew from experience that any plan Luffy had was a terrible one but decided to listen to him and see it out. He and the rest of the sailors would regret it soon.

Just Outside Cocoyashi Village

"W-Where am I?" Asked a slim, somewhat dark skinned teenager with medium-length black curly hair and a long nose, wearing an olive green plain bandana, along with goggles on his head, brown overalls with a white sash and no shirt and a blue and white striped armband on his left arm. He also carried a yellow satchel over his shoulder.

"About time you woke up." A feminine voice called out as the teen looked over to see who it was. She was an average-sized young woman with short, light blue hair, with a red ribbon tied around her head, and tanned skin. She had a tattoo on her right arm going across her chest, a bracelet on her right wrist, wearing a beige sleeveless shirt, blue pants, purple sandals and pink lipstick. "Sleep well?" she said sarcastically.

"Who are you…?" The teen said as he sat up.

"I'm Nojiko. I grow tangerines here, want one?"

After a brief argument and some introduction the teen now named Usopp learned that Arlong had been terrorizing the whole island for years and Nami stopping by for now to drop off some more money and that she was working for Arlong.

"What?! Nami's a member of Arlong's crew?" Usopp asked in disbelief. Nojiko nodded and went on to explain that she and Nami were foster sisters, and that the house that they were in was where they grew up. She then explained that their mother was long dead and only she lived with Nami and that she joined with Arlong and betrayed her village. "I can't believe it. She betrayed her sister, her mother and her village just to join with Arlong's gang?"

"Yeah, that's about right. A real witch, huh?" Nojiko said.

"Damn…" Usopp swore as he sat down. "...She had all of us fooled the entire time. Even after she risked her life to save my village. I don't understand, she seemed so happy with us, she was laughing and smiling. But she was in it all of the treasure."

"Smiling? Laughing? Nami? You don't say…" Nojiko said as she whispered the last part.

"We came here to try to convince her to come back with us, but I guess now that's pointless…" Usopp said before he froze and dropped his jaw as he remembered something.

"Is something wrong?" Nojiko asked as she saw Usopp look over towards like a robot.

"I just remembered a crew mate of mine was unfortunately caught by the fishmen before we got here. Shit...I hope he's okay...I hope he doesn't kill me."

Arlong Park

In a coastline area near the ocean with a large building, boasting several stories, a large, muscular, light blue sawshark Fishman whose most distinctive trait is his saw-shaped nose. He has long, black hair with a widow's peak reaching down to his shoulders, under a brown ushanka. He has a fin on his nape, surrounded by his hair, and the gills are located on both the sides of his neck. He had a sun tattoo is on the left side of his chest, while another tattoo was on his lower left arm.

He wore a short-sleeved, unbuttoned yellow shirt decorated by many black lightning-like spots, brown bermuda shorts a purple sash around the waist and simple sandals. He also sports a lot of jewels: he has a golden chain bracelet around his left wrist and two golden bracelets around each ankle, with straw-like decorations hanging from them. On his hands are what appear to be rings, decorated by colorful gems. This was the fishman pirate Arlong.

He was currently glaring at a man in front of him who was named Roronoa Zoro. He was tied up and had short green hair with three earring dangling off his left ear, bandages around his torso, wearing black trousers tucked inside black boots and a green haramaki around his waist. Zoro was looking at the fishman with annoyance as he was asked the same question again.

"I'm only going to ask one more time." Arlong said as he looked down at the tied up Zoro. "Why are you here?"

"I already told you ya half-fish bastard. I'm looking for a girl."

"You should really watch your tongue human." Arlong said with a sinister grin as he spat out the word human. "We fishmen are evolved creatures who can breath on both land and water. We are naturally born stronger than your measly species. That makes us the Lords of Creation, and to defy us is to go against nature."

"I'm getting sick and tired of hearing you spout that crap Arlong." A feminine voice called out from behind Arlong revealing a young, average sized girl, with short orange hair. and light brown eyes, wearing a green sleeveless shirt, black shorts, high heels and a tattoo on her left shoulder. Zoro looked at the girl in shock as Arlong looked behind him to see the girl.

"Why are you always so serious, Nami? You're special. You are our greatest navigator and a valued member of this crew."

"Say what you will, but I'm a lot smarter than any of you, that's for sure." Nami replied.

"What the? Why are you acting all friendly with them Nami? And what did he mean by 'our greatest navigator'?" Zoro asked.

"You know this guy, Nami?" Arlong asked.

"Don't be ridiculous, he's just another victim. I gained a lot of loot from them. You don't even realize that you've been deceived, and you still came chasing after me. You're just plain stupid." Nami said as she approached Zoro and sat down until she was eye level with him.

"So this is the person you really are. All along I thought that you couldn't stand pirates." Zoro said with a dark look.

"Surprised? Everything was an act. You'll understand better after seeing this…" Nami then showed Zoro her left shoulder and he got a good look at the tattoo on her arm, which looked exactly like Arlong's Jolly Roger.

'That's...' Zoro looked at the tattoo in shock.

"I'm a pirate, plane and simple. And a navigator for Arlong." Nami smirked at Zoro's reaction as he narrowed his eyes.

"Shahahaha!" Arlong laughed. "She had you guy completely fooled. It's no use she's cold-blooded. She betrayed her family for money, so you really shouldn't feel to bad. She is a witch" Arlong said. Zoro watched as Nami's face morphed in one of pain and raised an eyebrow.

"If I were you I would just admit defeat and try to forget the day you met her." Zoro smirked at Arlong's words.

"I don't need to…" Nami snapped out of her thoughts and looked at Zoro. "Cuz I never saw anything in her to be trusted in the first place. If she turned out to be a serial killer I wouldn't be surprised."

"Find then why don't you just get the hell out of here, I'm tired of your face!" Nami shouted as Zoro's smirk got wider and leapt back into the water.

"Huh?!" Most of the fishmen there said.

"Is he trying to swim away?"

"Even if he tried, he's tied up. That human can't do anything."

"Leave him." Arlong said.

'That idiot!' Nami thought before she jumped in after him, making all the fishmen watch in disbelief. She surfaced with him a moment later, both coughing for air. "What do you think you're doing?" She asked.

"That's my line, what do you think you're doing? Your cold-blooded huh?" Zoro said with a smirk. Nami scowled at being tricked by the swordsman before kicking his wounds, making him double over.

"You bastard!" Nami said before she started walking away.

"Oi, Nami. What are you planing for him?" Arlong asked.

"Lock him up. I'll take care of it." She replied back.

"Arlong-san! Arlong-san!" screamed a fishman.

"What's wrong, brother?" Arlong asked.

"My apologies, but this guy didn't come here alone. There was a long-nosed guy who was with him him, but I failed to capture him." the fishman reported as Nami and Zoro's eyes widened.

'What the hell Usopp!' Zoro thought. 'You left me for dead and got spotted anyway.'

"I think he fled into Cocoyashi Village." the fishman finished as Arlong grinned at the news.

"Cocoyashi huh." Arlong said. "Perfect timing. Now I have two reasons to go."

"It's time to go have some fun boys!" Arlong said to his crew as they all laughed. No one saw Nami at the doorway clenching her fist tightly.

Later in Cocoyashi Village, Arlong and some of his crew could be seen walking through the street as the townspeople hid inside of their houses while they did so. They then stopped as the stood in front of the only man on the street who was sitting on a bench. The man had scars all over his body and was was wearing a police uniform with short sleeves and pants and a pinwheel in his hat. Genzo was his name.

"So you're the fool who thought he could hoard weapons on my island?" Arlong asked.

"That's right." Genzo said. "It's a hobby of mine to collect them. Why? Is there a problem?"

"Yes, there is. Weapons bring nothing but evil and bloodshed. It would be hard for me and my men to keep the peace is someone were harboring them." Arlong said. As they were talking, Usopp and Nojiko were looking at them from a safe distance.

"That's Arlong?! He's huge." Usopp whispered.

"That's him." Nojiko said. "He's a fishman. He's got another 20 villages under his control." She explained to Usopp about the tributes they would have to pay 100,000 berris for adults and 50,000 berris for children in order for them to keep on living. "If even one person doesn't pay the monthly tribute, then what happened to Gosa Village will happen to us."

"Arlong destroyed that town just because of one person?" Usopp asked as he remembered the town he saw when he first came to the island. Nojiko nodded and explained that those were the rules and Arlong and his men don't care about human life. She stopped talking when she heard a yell, and looked over to see Arlong holding up a beaten Genzo in the air. "Genzo!" She yelled.

"This human has weapons." Arlong said. "Having them is a sign of rebellion. In order to prevent anyone in this village thinking of rebelling, I will kill him right here and now!"

"Arlong!" The fishman turned his head to see Nojiko standing behind him. "We've paid your tributes for eight long years, why would we rebel now? Let him go!"

The people from the town start coming out of their houses and protested towards Arlong as he continued to hold Genzo up in the air. "Holding weapons showed that he was planning a rebellion against me." Arlong said. "Anyone who dares try to go up against me will be destroyed. Rebellions will not be tolerated."

"Everyone, go back inside!" Genzo said. "It'll be pointless to fight against them. We can't let those eight years we lived here go to waste, if we do anything now it will have all been for nothing."

All the villagers stopped what they were doing as Arlong laughed before raising him higher in the air. "Well said, I agree with you. It's good to know that even disgusting insects like you enjoy being alive!" he screamed as he threw Genzo towards the ground.

"There is no way any of you will come close to the perfection of the fishmen. Shahahahaha!"

"Damn you!"

"Don't move!" Genzo shouted before the man could do anything. "Don't fight them, no matter what. Your deaths will mean nothing. You must continue to be patient. Even if I die…"

"Nice speech." Arlong said as he grabbed a hold of Genzo again and held him high above his head. "Pay close attention humans! Let this be a lesson to you all!" he scream as he brought Genzo's head towards the ground.

"EXPLODING STAR!" Usopp yelled as he shot at Arlong. The explosion cause Arlong to release Genzo as everyone looked on in shock.

"Huh, what happened?" One of Arlong's men asked.

"Look! Over there!" Another fishman shouted as everyone looked towards a building behind them and saw Usopp standing there dramatically with his legs shaking. "Who the hell is that?"

"I am the great warrior of the sea, Captain Usopp!" Usopp shouted. "Thousands of men all over the world fear me, they call me the demon king Usopp! I have thousands of men under my command, all loyal and willing to risk their lives for me!"

"Arlong-san! That's the guy I told you about! The long-nosed guy who got away!" A fishman said as Usopp stiffened.

"Bring on your thousands of men." Arlong said in a low voice. "I'll crush them one by one. Repulsive human…" he said before looking at him in a crazy manner. "WHAT CAN A CREATURE LIKE YOU DO TO ME!?"

'The exploding star did nothing and my threats didn't work, and he looks pissed!' Usopp screamed in his head as Arlong picked up the building he was standing on. Usopp screamed as Arlong's men begged him to stop.

"With Gosa Village destroyed we can't afford to lose any more tribute money!"

"If we lose some we can always get more!" Arlong said before throwing the building into another one, destroying both of them and making the villagers shout about their poor village. After the dust had settled down Usopp emerged from the wreckage almost unscathed before he took off running like a little girl when he the fishmen realized that he survived, meanwhile Arlong was being held back by most of his crew as they tried to calm him down by taking him back to Arlong Park. Arlong angrily agreed with his brothers and walked back with half of them while the other half took off to capture Usopp.

After the fishmen had left the villagers had all gathered around Genzo as he was being treated by a doctor about his injuries when a familiar voice interrupted them.

"Hi everyone." The villagers turned around and saw Nami walking towards them holding some flowers in her hand. "Long time no see."

"Nami?" Most of the villagers said before they all turned away and ignored her as she walked past them.

"What's wrong? It's rare for you to come to Cocoyashi anymore." Nojiko asked.

"I heard quite a commotion." Nami said as she looked towards the wrecked buildings with with a sad look. "Arlong, huh?" The street went silent as the only thing that could be heard was the sound of Genzo's pinwheel flying in the wind.

A while later Nami could be seen sitting in front of a lone grave on a hillside overlooking the sea that had a simple wooden cross as a marker with the flowers she had set down in front if it.

"I only need to get 7 million berries." she said.

"As usual, your reputation is already getting worse." Nojiko said as she watched Nami sit there.

"I am a pirate after all. Arlong can be pretty reasonable when he wants to be, I just need a little more time and money. Soon i'll have 100,000,000 berries, and I'll be able to buy the village back from him." Nami said with a smile as the wind blew past her face.

'With the way things are going now I might not even need to wait for him.' She thought as she thought back to a blond haired man with a fox-like smile. 'I wonder if you even remember the promise you made?'

Arlong Park

"Man, what a mess." Zoro said as he looked around Arlong Park. A short while later after the fishmen had taken him away and looked him up in underground, Nami had walked into his cell, given his sword back to him and told him to leave the island immediately and to leave her alone. After he had made his way back above ground he was meet with the a handful of Arlong's men waiting for him and attacked him the moment he stepped outside.

He could now be seen sitting on Arlong's 'thrown' now wearing a blue button-up shirt that was left open and looked over the bodies of the multiple fishmen he had defeated.

"She told me to run, but the only place I could go was here." Zoro said as he looked out towards the ocean. "But, I did promise Luffy that i'd bring her back. I wonder what he's up to. This are getting complicated here."

Naruto sat on the side of the boat and looked forward as he and the rest of the people on board saw Arlong Park in the distance as they slowly got closer towards the island. He felt the wind brush past his face as he narrowed his eyes in determination as he saw Arlong's hideout.

'Just wait a little longer Nami, I'm going to keep that promise I made to you.' Naruto thought as he turned towards his smiling little brother. "I know your plans are ridiculous Luffy, but i'm actually surprised that this one is actually working." He commented as he saw the sea cow that had hit him earlier pulling the ship towards land.

"Do you really have so little faith in Luffy's planning abilities?" Gin asked.

"Yes I do." Naruto said as he continued to look towards Arlong Park. "I've known Luffy his whole life and his plans usually end up with buildings being destroyed, him being thrown into the ocean or we end up crashing into something. I'm just waiting for this thing to backfire any minute."

Gin and Sanji who was listening looked at the blond with raised eyebrows before shrugging it off and looked toward the island.

"Yahoo! Faster, let's go faster!" Luffy shouted in excitement as Yosaku pointed towards a large structure ahead of them. "There it is! Arlong Park, dead ahead!" Yosaku shouted.

Luffy grinned as he told the sea cow to speed up and shouted. "Just hang on Nami! We're coming for you!"

A nice-short introduction chapter for you all. I hoped that you liked it and if you did, review and tell me what you think. No flames please.

M.S OUT! :)
