Please read! (A/N) This story will follow the manga and my OC will just be a fighter and all arcs will be the same but with my guy so One piece will only have an extra guy that won't make me create a whole new large arc. Also this story starts at the Arlong arc because it is unnecessary to start from the beginning. Wait till my OC gets into the story and it won't seem like a manga turned story thing as much. There will be small arcs of my own here and there but nothing special. Also this chapter will go from the start of the arc to the part where Luffy gives Nami his hat while skipping the flashback and most of the chapters just to not make this chapter too long and because if you're reading this story you should know what happens anyway. Enough of the long AN now...

Chapter 1- Arlong Park

Once upon a time, there was a great pirate. His name was "Gold Roger". He had conquered every single treasure that existed. His last words before his execution have inspired pirates around the world.

"Hmph. Want my ultimate treasures? It's possible... I will give them to those who can find them. I have gathered everything in this world and already hidden them in "that" place." says Gold Roger.

With the cheers of every person there the world entered into the pirate era.

Luffy finally convinced Sanji to join his crew and be their chef. They are currently sailing on clear blue waters. However, there is currently a lot of sobbing going on on the ship.

"How long will you be crying? You should be happy." says Luffy.

"But I am very touched from departing from those chef-sempai." sobs Yosaku.

"I thought you should have been through these kinds of situations many times." says a only slightly annoyed Sanji relaxing on the side of the boat.

"I want Nami to get back to us soon so we can go to the Grand Line." says Luffy happily with his hands up in a cheering position.

"Why do you look so happy? Even though Nami-san might come back and join us, are you sure you want to go to the Grand Line with only five people?" asks Sanji with a cigarette in hand (Thats right... not a f*cking lollypop). "You will be in doom because of you underestimation."

"I will gather more people in the Grand Line because it is a paradise." says Luffy with a grin on his face. "Maybe here too if I meet another interesting person!"

"Isn't the Grand Line also known as a pirate graveyard?" questions Sanji still relaxing on the side of the boat.

"Before departure, some people called the Grand Line, "A paradise." Honor told me that." says Luffy with a goofy grin on his face.

"Old man said that? For me, everything's OK as long as Nami-san is with me. I wish to stay with her alone." said a dreamy Sanji with a perverted smile upon his face and sporting a blush to go with that.

"I think your dreaming, Sempai! You know way too little about the Grand Line. And this time if Zoro-sempai knew about that place, maybe he will come back with me. The place where Nami is heading to, is an incredibly dangerous place. You should understand this!" Shouts Yosaku with a serious expression mixed with anger.

"Yes! Do you want to eat!" shouts Luffy suddenly with a cheering motion.

"Didn't you listen to me at all? You should know something about the place we are heading to from now on. First, about the Grand Line. The reason that the Grand Line is called a pirate graveyard is because that the Grand Line consists of three main factors." Yosaku puts up three fingers. "One of that factors is the Shibukai."

"Shibukai?" says Luffy with an uninformed tone.

"Another word, they are seven people who have been granted to become "legal" pirates from governments around the world." Explains Yosaku.

"What? How can pirates become legalized?" Asks Sanji.

"?" Luffy looks at Yosaku with confusion.

"Shibukai are the pirates who have the right to become a pirate. They will invade only barbarian civilizations and give some commission to the government. Other pirates call them "Dogs of the government." But they are very strong. Mihawk, the guy who defeated Zoro, is one of the Shibukai." Further explains Yosaku with a teary look as he recalls the fight between Zoro and Mihawk.

"There are seven people who have that awesome power? Wow! Super! Those Shibukai are so awesome!" Loudly shouts Luffy with an impressed look.

"..." Sanji looks at Yosaku.

"The real problem is one of those seven Shibukai. Jinbei, the captain of the Mermaid Pirates." said Yosaku with a serious expression on his face.

"Mermaid? I've never seen one before." says Luffy with his arms and legs crossed.

"Speaking of mermaids, the mermaid island in the Grand Line must be very famous, right? I think there will be many beautiful mermaids living in that place." Says Sanji with a pervert look and input, his thumb and forefinger under his chin.

"Jinbei left some monsters in the East Blue sea in exchange of becoming one of the Shibukai." says Yosaku with his hands resting on his knees and looking down on the floor of the boat.

"Did it look like this?" asks Luffy showing a crappy and crude drawing of a fish with what might be legs but that can't be determined.

"That's a fish not a mermaid!" Shouts Sanji.

"Won't you pay attention? OK I will not talk about the history anymore. The place where we are heading is called "Arlong Park." Arlong is one of the mermaid pirates who is as strong as Jinbei, one of the Shibukai. That place is under control of Arlong. Talking about his strength, Don Creek will just be history!" Exclaims Yosaku with another one of his serious expressions.

"But you came back to the restaurant before you caught up with her right? How can you be sure that her destination isn't just in the same direction?" asks Sanji.

"Me and Johnny have a strong feeling about this. Based on what happened earlier with Nami seeing the wanted posters, and one in particular, we could easily come to the conclusion that Arlong Park is where she is heading." Explained Yosaku.

"How's this?" asks Luffy holding up another picture of a "mermaid".

"Isn't that just the same one as before only upright?" Asks Sanji. "But what does Nami have to do with those fishmen? Could she be a mermaid? That would explain her beauty..."

"Like this?" Asks Luffy with the same "mermaid" as before but only this time with hair.

"YOUR DEAD MEAT!" Exclaims an angry Sanji.

"Do you even understand what I'm trying to say here?" Shouts Yosaku.

"Ya. There is some strong fishman dude, got it." Says Luffy.

"No you don't! You can't imagine just how powerful he really is!" Shouts Yosaku.

"Well, I'll see when I get there." says Luffy nonchalantly.

"Ya, don't worry about it Yosaku." Says Sanji.

"God! Talking to you two is useless!" Exclaims Yosaku angrily.

"Anyway, Let's eat! What do you want?" Asks Sanji.

"Meat on a bone!"

"Stir-fried bean sprouts!"

"Alright! Just leave it to me!"

"Ahhh. It sure is nice having a cook around!" Says Luffy with his usual cheerful voice.

"I wish I could hurry up and cook for Nami-san instead of you idiots." says Sanji.

"Stir-fried bean sprouts! Big-serving!" shouts Yosaku.

Meanwhile a seagull caws in the northwestern region of East Blue. A pirate flag currently in the ownership of Arlong and his crew flaps in the breeze.

"Here is the pay for this month. Take it." Says the owner of a webbed hand as it pushes a stack of money across a small round table.

"As always thank you. Chichichi. You really know how to get by in this world..." says a mouse faced 16th branch Captain Nezumi.

"Shahahaha! What are you being so reserved for? After all money makes the world go round!" Says the owner of the webbed hand, "Arlong the Saw" captain of the Arlong Pirates and a saw-shark type fishman. "Money's good! There just isn't something more reliable than money. Ain't that right?"

"Certainly." Says Nezumi.

"Shahahaha! I despise humans but humans like you who know how this world works are a different matter." Says Arlong relaxing in his beach chair.

"...Well if business is over, I'll have to get going now. It'd be bad to have my ship docked in a place like this in the middle of its patrol..." Says Nezumi while getting out of his own beach chair across from Arlong.

"You're always in a hurry, aren't you? You should stay awhile and drink with me now and then! Live a little bit! If anyone rats you out to HQ, I'll kill him for ya." says Arlong his grin showing off his pointy teeth.

"No, it's fine... Excuse me then." says Nezumi while turning around to leave.

"Hey! The captain is leaving! Escort him out!" Commands Arlong.

"Yessir! Get into the octopus pot, I'll give ya a lift!" Says Hachi an octopus type fishman.

"Thank you." Says Nezumi.

"You have a funny looking face, not to mention that your name is Nezumi. C'mon! Your face alone is enough of a joke already! Ahahaha!" says Hachi while laughing. (Nezumi = mouse in japanese)

"Hachi! Watch your mouth! The captain is our valued client." Scolds Arlong.

"Oh! Sorry about that captain." says Hachi in an apologetic tone.

"Sorry about that, he has got quite the mouth on him." Says Arlong.

"No no. It is quite alright. Chichichi." Says Nezumi. These fishmen give me the creeps... But their money is good.

At Arlong Parks east gate there is a small commotion involving a young boy and a redheaded girl by the name of Nami.

"Hey you! Stop right there! I'm gonna kill Arlong because he killed my dad! So if you don't get outta my way I'll kill you too!" Shouts the young boy with tears streaming from his eyes and holding a sword pointing it straight at Nami.

Nami hits the kid with her staff and yells at him to go home. She dropped some money next to him and continued her walk towards Arlong Park angry at the kid because he was about to throw his life away.

Nami walked into the mansion and Arlong greeted her with enthusiasm. A feast was created to celebrate the return of their crew officer Nami.

-Time skip to Luffy and Nami in the village-

"Let's go everyone! Even if we may not win, let's show them our spirit!" Shouts Gen in an encouraging way. Swords and weapons in the air as a sign of rebellion.

Nami was on the ground crying at what everyone was doing. Shahahaha! "Arlong!" Nami takes her dagger and stabs at her Arlong tattoo. "Arlong! Arlong! Arlong!" She repeatedly stabs at her tattoo until a hand stops her. She turns around and sees Luffy looking at her while holding her hand in place from hurting herself.

"Luffy...! What do you want? You don't even know anything!" Shouts Nami with tears still flowing out of her eyes.

"Your right. I don't know anything."

"This has nothing to do with you! Didn't I already tell you to leave this island!" Shouts a crying Nami while throwing dirt behind her at Luffy.

"Ya. You did."

Luffy continues to look at Nami as she continues to cry. Then she turns around to look at Luffy with a crying and completely sad face and sobs out, "Luffy... Help me..."

The shadow over Luffy's eyes darken as he puts his hand over his treasured hat. Luffy takes off his hat and places it on Nami's head. He walks a little ways off, takes a huge breath and yells out, "OF COURSE I WILL!" Luffy walks down the road with a pissed expression and is joined with the rest of the crew. Zoro. Sanji. Usopp.

Luffy says but two words with his serious face as he walks towards his crew, "Let's go." This was all the incentive they needed to follow him to Arlong Park.

"ROGER!"

-At the docks-

A small boat floats towards the docks carrying a sleeping passenger. Said passenger had his hands behind his head, a peaceful expression on his face, and a snot bubble coming out of his nose. To everyone he might look just like your average drifter. The thing that makes him stand out though is his twin bisentos by his side.

The snot bubble pops and the man is instantly awoken. With a sleepy expression he stands up, stretches, jumps onto the wooden dock and looks around. He has messy brown hair, milk chocolate eyes, goofy grin, no shirt showing off his well built chest, white cargo shorts with a black studded belt and a skull on the buckle, a duel sheath on his back, and black steel toed boots. With his twin bisentos strapped to his back he calmly walks towards Arlong Park a wanted poster in hand.

With a dramatic scene pause he says, "Finally I got here. Now time to test my skills and have some fun!"

(A/N) My skills are really rusty from not writing for a while. Either that or following the manga really limits what I can write. Anyway with the addition of my OC I can now hope to write this story better as I have to actually change things instead of reading the chapters one by one. No romance will be in this story as it will kinda ruin the adventurous mood. R&R please!
