Chapter 1: The D. Sisters

In the middle of the vast blue sea, a cruise ship was sailing peacefully and its passengers were enjoying a high class party. On the top of the watchpost a man was scanning the seas, and below two guys was fishing for a mysterious barrel in the sea. The watchman was looking through his telescope, and from afar was a pirate ship with a certain jolly roger.

"It's the Alvida Pirates!" he yelled.

On said pirate ship, a large crowd of pirates has gathered, however they gave away space for the two in the middle. One was the pirate captain Alvida who had to be the most hideous thing that had came from the East Blue, it was surprising that she was a human being, much less a woman. On the other end was the cabin boy Coby, a scrawny pink-haired boy, with round glasses, who looked like he was asking to be picked on, it didn't help that he was shaking in his shoes.

"Coby," Alvida spoke. "Tell me, who is the most beautiful woman in all of the seas?"

"W-Why that would be you Miss Alvida," Coby lied, but it was hard to tell through his fear and the shaking of his voice.

"That's Right!" she hit her large mace to the floor of the ship, and it made a hard, thud. "Men get ready to raid the ship!" cheering from the crew resonated, as they charged to the cruise ship, cannons firing, and men with swords jumping to the ship. "Coby why aren't you on the ship yet?"

"U-Um I"m n-not really cut out for this," Coby stuttered as he created his excuse.

"Too bad, now get out there!" Alvida grabbed hold of Coby and threw him onto the ship.

Amidst the chaos of the ballroom, a certain girl wth orange hair snuck out and managed to sneak aboard the Alvida Pirates' ship. She began searching for the treasure room, and she felt as if she was close, that was when a pirate left a room and looked at her.

"Huh?" he said looking at the girl. "Who're you?" The orange-haired girl smiled, and kicked him in the crotch as hard she could. Looting the place, she grabbed as much as her large sack could carry, and hauled it away. Running back to the cruise ship, she was stopped by some pirates.

"Looks like we got a rat here," one of them sneered. "If you don't want to die you should give that to us."

"Dammit," she thought, as the pirates inched closer to her, she backed up to the railing behind her, and her back hit it. Unfortunately she had no where to run except for the ocean's below, she had heard a small thump below. At that moment the sounds of combustion was heard behind her, the menacing pirates turned into frightened puppies at what they saw. She turned her head to see a flaming figure hanging off the railing, scared she stepped away, that was until the flames dispersed. It revealed a young woman in her early 20's, she had long wavy hair that was up to her waist, narrow black eyes, and freckles across her face. She wore black leather boots, loose black shorts, a black bikini top to cover her fairly large breasts, and a orange cowboy hat.

"Yo," she winked and took a quick look around. "I see what's going on..." The mysterious woman snapped her fingers and set the pirates asses on fire. The orange haired girl was shocked but used this miraculous moment to escape.

"Thanks I owe you for this," she said trying to run away.

"Hold it!" the black haired girl demanded. "Have you seen a girl here, 17, short black hair, large chest, wears a straw-hat? The name's Anne or Ace whichever."

"No, I'm sorry she probably may be somewhere else on the ship though," the orange haired girl ran off. The woman got off the railing and tipped her hat.

"Dammit Lu where are you?" she thought to herself. Elsewhere on the cruise ship the unfortunate Coby was looking for something that would please Alvida, to save his hide. He stumbled upon the kitchen and found a large barrel in the corner.

"This is a large barrel," he thought, as he tried to pick it up. "Wow it's heavy, must be full of wine or sake, Alvida will love this." At that moment three pirates entered the kitchen.

"Oi Coby you hiding out here?" the pirates laughed.

"N-No of course not," Coby flinched. "I just found this barrel of wine."

"Perfect I was getting thirsty," one of the pirates walked up to the barrel.

"No you can't do that! Alvida will kill us," Coby explained.

"If you don't tell her that is," one of the pirates said, the other was about to open the barrel.

"Now let's see here-" "I SLEPT GREAT!" a strange girl popped out the barrel with such force that knocked out the pirate. The strange girl was in her late teens, had short straight black hair, and a small scar under her round black eyes. She wore straw sandals, short ripped jeans, a red button vest, and a straw-hat. After her strange pop up she looked around to see those around her, and her eyes locked on to the man on the floor.

"Who's this guy?" she said innocently.

"Who the hell are you?!" the pirates yelled at her.

"Hmm, y'know he'll get sick if he sleeps like that," she explained.

"Your the reason why he's like that," the pirates got sick of her and unsheathed their swords. "Hey, you better quit screwing with us or else..." despite how threatening the pirates projected themselves as, the girl turned to Coby.

"I'm hungry, do you know where the food is?" she asked, surprising Coby, but the other two pirates weren't pleased. They readied their swords to attack her, Coby noticed this and was about to shout.

"Don't you ignore us!" as the pirates swung their swords almost upon contact to her, the tips snapped off, scaring the swords users.

"W-Who are you," Coby said in awe.

"My name is Monkey D. Luffia or Luffy for short, and I'm going to be one of the Pirate Queens," Luffy said happily. This caused the other two pirates to run away. Back on deck Ace was walking through the ship to see plenty of pirates lunging things to the pirate ship. She stumbled upon the ballroom where multiple hostages were, and a group of pirates guarding said hostages. One of the pirates saw her however, and a few charged at her.

"Geez," Ace sighed. "Looks like she ain't here either." At the moment when one of the pirates was close to her, she kicked his face hard enough to send him flying. The other pirates flinched, but she didn't waste this oppurtunity and snapped her fingers lighting a few of the pirates clothes on fire. Running towards the ones with guns she beat them down hard, causing fear in the rest as they fled. "Too bad I can't use too much of my powers or else this entire ship will go up in a blaze," Ace looked at the hostages and decided to untie them. Hearing thank you's over and over in the process.

"Thank you ma'am, but can you help me?" the ship captain asked. "I need to contact the marines but they are too many pirates."

"That's a tall order to be asking a lady," Ace tipped her hat. "Fine I'll help, but you give me a boat, food, and water." She winked at him.

"Done," the captain answered. Meanwhile in the storehouse, Luffy was stuffing herself in apples, as Coby watched silently.

"So your name's Luffia, mine's Coby," Coby introduced himself.

"Call me Luffy, man these apples are good," Luffy said.

"You popped out a barrel though, how come?" Coby asked, curious for the answer.

"Oh well, I fell out my ship in a whirlpool, and hung onto the barrel for dear life, I got inside and stayed in there for a couple of days," she explained.

"What for days how did you survive?" Coby's mouth hung agape.

"Actually it was kind of fun, it was a first for me," Luffy laughed giving a smile brimming with innocence. Coby was shocked at her comeback, and wondered who she was. "Anyway, where am I?"

"Oh your on a cruise ship, unfortunately it's being raided by pirates," Coby said solemnly.

"Are you a pirate?" Luffy asked.

"Oh no, I never had any intention of being a pirate, a-actually I'm more of a cabin boy," Coby explained, and started to explain everything. "I was just on another fishing trip and that was when the Alvida pirates kidnapped me, once they learned I had good navigation skills I became their cabin boy... for two years."

"Your an idiot," Luffy stated bluntly. " Also a coward, I don't like people like you."

"Gee wiz, thanks for your honesty," Coby said sarcastically. "But your right, I'm a stupid coward. I couldn't sneak out no matter what opportunity came for me... O-Other than that, were you serious."

"Bout what?" Luffy asked.

"Becoming the Pirate Queen, one that means your a pirate, and two you have to look for the most elusive treasure that has ever existed, the ONE PIECE!"

"Correction I said I was going to be one of the Pirate Queens, everything else is right," Luffy smiled.

"Huh what do you mean?" Coby asked.

"I mean~ that me and my sister are both going to be the Pirate Queens!" Luffy said happily.

"What!" Coby hung his mouth open. Meanwhile on the captain's deck.

"Yes yes hello! Please respond the Alvida Pirates have raided our ship," the captain began calling for the marines. Behind him Ace was bringing hell upon the pirates that tried attacking her, she had this abnormal strength that made it easy for her to bring a beating to almost any one that came her way, added with her strange combustion powers, this all the more made the ship's captain glad that she was on their side.

"Damn these guys are boring," Ace complained, and looked at the captain as he hung up his phone.

"The Marines will come here soon," the captain explained. "Also I'm sorry about this I know your terribly worried about your sister."

"Nah don't mention it, she should be fine," Ace said walking towards the window, and the sight that caught her attention. "Holy Shit! A Sea Monster!"

"That would be Alvida," the captain explained.

"Well its boarding the cruise," Ace laughed.

"What!" the captain yelled his face against the window. Meanwhile Coby stared at Luffy unable to form words.

"S-So both of you are going to be the Pirate Queens..." Coby stuttered.

"That's Right!" Luffy held a huge smile on her face. "We don't have a crew yet, but we plan to have ten more crewmates."

"T-That's impossible you have to fight hundreds of other pirates each more frightening than the last, not only that you have to go through the Grand-Line or the pirate grave-yard, you have to have at least armies upon armies of crewmates or else-" Luffy took note to hit Coby up-side his head. "Why did you do that?"

"Cause I felt like it," Luffy said, Coby rubbed his head to soothe the pain. "Anyway we want to do this, we made a promise to someone important, we wouldn't mind if we died trying," Coby awed at Luffy's words, and became inspired.

"Y'know what I need to stop hiding behind my fear," Coby said suddenly. "The one thing I've always wanted to do was become a proud Marine, what do you think, Luffy?"

"A Marine huh?" Luffy spoke softly.

"Actually," Coby gave it some thought. "I will become a Marine, the best Marine there ever was, and will arrest that ugly pig Alvida!"

"Who Are You Going To Arrest Now Coby!" Alvida suddenly appeared from the ceiling crushing the storehouse, under her massive weight. It turns out Alvida wasn't the only one around, all her pirates encircled the two.

"When I heard of an intruder I expected the great pirate hunter Zoro," Alvida sneered. "Instead we got a little girl who doesn't know her place and filling Coby's head with ideas. Tell me girly are you with the marines?"

"No I'm a pirate," Luffy stated boldly. The pirates began to laugh madly.

"Amazing a lone pirate trying to make it on her own," Alvida sneered, then turned her attention to Coby, smiling as he began shaking in his boots."Now Coby who's the most beautiful woman in all the seas?"

"O-Of c-course th-"

"Hey Coby who's this cow?" Luffy stated plainly. At that moment all the pirates and even Coby awed in fear at what little she said. "And I'm not alone either..."

"There she is," Ace looked at Luffy face off Alvida. "Now I can't let you have all the fun Lu."

"Miss what are you doing," the captain shouted worriedly as Ace hung off the edge and jumped off and her feet soon was engulfed in flames. Ace soon rocketed from the captain's quarters to where the commotion was.

"Found ya Lu," Ace smiled.

"Ace!" Luffy hugged her with all her strength. Almost everyone else was shocked to see Ace fly down to the deck like a meteor crashing down. Coby fell and was staring at Ace with fear in his eyes, she had seen this.

"Now who's this," Ace leaned in scaring Coby more.

"So they do exist," Alvida said under her breathe. "Now I can guess your with this girl, no matter a Devil Fruit Eater is nothing against me."

"Huh is that a challenge," Ace mocked.

"Wait Ace, Coby didn't finish what he was saying," Luffy stepped in. "Well Coby what were you going to say?"

"I was going t-to s-say," Coby knew that every word he was going to say will affect what will happen today and the rest of his life, but... "I WAS GOING TO SAY THAT YOUR THE UGLIEST THING THAT THE SEAS HAVE CONCEIVED, NO WHERE NEAR THESE REAL BEAUTIES! And if you hadn't kidnapped me before I would have become a great marine and arrest your FAT ASS!" he took his chances.

"Well..." Ace blurted, Luffy smiled, the pirates were scared, and Alvida.

"You little SHIT!" Alvida was pissed. She swung her mace into the air, and Coby stared blankly mouth wide open with dis-belief.

"I-I can't believe I said that," Coby mumbled, getting ready for the mace to make contact with his head, but it didn't. Instead of hitting Coby Alvida's Mace had rebounded off Luffy.

"W-Wha!" Alvida stuttered.

"You said that like a true Marine," Luffy winked at him, then leapt at Alvida. "Ok Ace let's deal with this hag!"

"I'm not sure what happened but ok!" Ace also leapt at Alvida fire enveloped her hand.

"Gum Gum Bazooka!"

"Fire Fist!" both Ace and Luffy attacked Alvida with an attack that sent her flying, all the pirates began to cower in fear at spectacle they had just witnessed. Coby looked at them with overwhelming awe.

"What are you two?" Coby but it was too low for them to hear.

"Hey Lu, while I was looking for you I got a new boat with tons a food," Ace laughed.

"Really!" Luffy smiled with delight.

"Yea also we should be leaving soon the Marines will be here any second now," Ace explained.

"Ok!" Luffy was about to run with Ace to the new boat.

"Wait Luffy take me with you," Coby grabbed onto Luffy's shirt. "If I stay here the Marines will think I'm also a pirate, and I want to become a Marine!"

"Luffy what are you waiting for," Ace jogged in place, and Luffy took hold of Coby's shirt and carried him with her.

"We got one more friend," Luffy cheered, and they ran to their new boat. After awhile the three were finally at sea enjoying the calm waves, and finally caught up to what happened.

"Thank you again Coby for helping Lu, she's a bit of a nut," Ace teased, Luffy just stuck her tongue at her older sister. "Anyway here you go," Coby's hair started ablaze, and he scrambled to put it out. "That's for grabbing onto her clothes." Coby finally managed to put his hair out, and saw make a threatening glare at him, though Luffy didn't notice that.

"Anyway..." Coby was trying to change the subject. "You both said that you were going to looking for the One Piece, that means going to the Grand Line."

"Yep," Luffy spoke.

"But that's the Pirate Grave Yard, you can't just go there by yourselves especially not on this thingy," Coby warned.

"Well we're both strong by ourselves, but I guess a small crew and bigger boat would help," Ace thought about it.

"A small crew!" Coby shouted. "You need a grand crew! Over thousands of men at least, maybe even millions!" Luffy took the moment to hit Coby.

"Why'd you do that?" Coby asked.

"I wanted to," Luffy said.

"Ace please tell me your considering this," Coby jaw dropped when he saw Ace asleep her head bent back. "Let's just head to the nearest island," Coby sighed.

I hoped you like this. I felt inspired to write this after a binge on One Piece, and reading a lot of other fanfictions, especially those that gender-bend Luffy. Please tell me what you thought, and I'll try to write the next chapter within the week.
