Author's Note: This might be my biggest undertaking in my fanfic writing yet. I've gotten interested in One Piece and wanted to write my own fanfic about it. When I remembered I wanted to also write a Harley Quinn fanfic, I thought this might be a good shot. And thus, Captain Harley Quinn was born. This was a work in progress that I have been brainstorming for over a month. This chapter alone took several rewrites.

In this retelling of One Piece, Harley Quinn and her crew will be the allies of the Straw Hats. Together, they work to conquer the Grand Line and seek out the One Piece. If anyone has any suggestions for who they'd like in Harley's crew, I'm open to suggestions.

Hope you all enjoy the story. Hope I do it right. Any and all comments are welcome.

The East Blue, one of the four corners of the Earth with the Grand Line at the center, was a good place to start for our central character. She was a tall, athletic woman with pale-white skin, blonde hair and a black-and-white, skimpy outfit. She sailed across the sea on her boat taking in the sweet feeling of the ocean breeze. With her metal bat hung over her shoulders, she was ready to take on the entire ocean.

There was just one little hitch: her ship was currently sinking. No matter how hard she tried to scoop it up with buckets and tossing them out to the ocean, she couldn't stop the ship.

"Come on! Come on! The last thing momma needs is wet socks! Seriously, the one ship I stole from that shady asshole, and it couldn't handle one trip over the Red Line? How am I going to… Oh, wait. Land ho."

Across the ocean, she was fortunate enough to spot an island less than a kilometer away. She just had to keep the ship going long enough to make it to shore. She almost didn't make it. Thankfully, the crow's nest was the last to go, and she stood on top of it until she was close enough to plant her foot on the land.

"All right. Now that all that's said and done, I just need a new ship. Now, where can I find one?"

Once she was on safe on the island, she found herself surrounded by a village. All around her, shacks and houses were erected high. But the strange thing to her was that there was no one in sight. She looked around finding no one around.

"Hello? Anyone here? Bonjour? Census bureau? Nanu-nanu?" Still, there was no answer. "Huh. You'd think things could only get mysterious at the Grand Line."

The celebratory sound in the distance answered her question. From afar, she could hear the sound of a crowd of men shouting from up the hill. She smiled in relief realizing she wasn't alone in this town.

"Well, it sounds like I have a party to crash."

The pirates were irritated as a great insult happened under their noses. Their flag had a ceremonial skull-and-crossbones on it, but there was a key detail that made it stand out: the round, red nose at the center of the skull's face.

These were the Buggy Pirates.

At the center of the party, their clown-like captain stood on top of his table. He wore an orange jacket that matched his hat. He also had on a pair of white gloves, green pants, and a red-and-white striped shirt under his purple scarf. His face was painted with blue stripes above his eyes and bones on his forehead along with red lipstick that matched his big, red nose. He snarled before shouting for his crew.

"Listen up, everyone! We still have a thief who stole my map to the Grand Line! Either somebody brings her to me or I will give everyone a flashy demise!"

"YES, CAPTAIN BUGGY, SIR!"

Buggy sat back down at his chair with nothing but a drink in his hand which he sipped from. That's when a crewmate of his ran up to him.

"Captain Buggy! Captain Buggy!" he shouted. "There's someone at the front gate!"

Buggy's scowl turned to his crewmate. "Who?"

"It's a woman dressed weird, sir. I think she's wearing clown clothes."

Suddenly, a vein bulged inside of Buggy's forehead. He sneered angrily. "What was that?"

"Uh… I said she's wearing clown clothes."

"WHO HAS A CLOWN NOSE?!" Buggy asked loudly as he thrusted his hand right at his crewmate. That's when his special ability activated.

All around the world, there are special fruits called Devil Fruits. Whoever eats one of them gains a special super power at the cost of the ability to swim. In Buggy's case, he ate something called the Chop-Chop Fruit, which allows him to detach parts of his body and control them even after separation.

Buggy's hand popped away from his wrist and he used it to choke his crewmate who he thought had just insulted him. Everyone gasped in fear seeing their friend in that position. He gagged and struggled to breath as Buggy's hand lifted him off the ground. He stayed there for a full minute before Buggy finally released him and let him fall on the floor to catch his breath.

"Don't insult me again or I won't be so merciful next time." Buggy warned. "Now, find this girl and bring her here."

"Yes, sir, Captain Buggy, sir!" all the pirates exclaimed at once before making their way to the front gate.

At the front gate, the pale girl kept knocking on the wooden gate in front of her. She didn't hold back on her knocking as she waited for an answer.

"Hello? Anyone here? I know someone's there. I can hear you partying from across town. Hello. Hello. Hello. Hello. Hello. Hell…" She was cut off by the door opening in front of her. "Ah. About time. This will be reflected in your tip."

She walked in expecting a warm welcome. Instead, all she was stopped by a bunch of swords pointed at her face. The Buggy pirates gathered up in front of her holding her at sword point. She looked around curiously.

"I take it you guys aren't the welcome wagon?" she asked.

Buggy sat at his table waiting for his crew to return. When he heard the sound of footsteps growing behind him, he smiled and turned. "About time, you… GAH!"

Buggy's eyes widened as soon as he saw the pale girl dragging the beaten and bruised body of one of his crewmates. Other than with her unconscious victim, she came alone with her bat hung over her shoulder. Buggy's surprise then turned to an angry growl as he sped up to get in her face.

"Hey! What's the big idea, lady?"

"Me? I could ask you the same question. I half-expected a red carpet, and these chumps of yours wanted to pick a fight with me. And they weren't really that tough. One swing of this beauty here, and they were down for the count." She held up her bat to present to Buggy.

"Listen here, girly. Perhaps you have no idea who it is you're up against?" Buggy said. "I am Captain Buggy of the flashy Buggy Pirates. And if you are so unfortunate enough to get on my bad side, then you are… HEY! LET GO!"

The girl had already reached out and grabbed Buggy by his big, red nose. She yanked on it closer to her and squeezed it while Buggy himself was straining to endure the pull.

"Wow. Nice nose. It almost feels real."

"LET GO, YOU PSYCHO!" Buggy demanded before smacking her hand away. After tending to his nose, he growled fiercely at the pale girl who assaulted him. "You're gonna pay for that, girl!"

Buggy shot out his hands that popped off of his wrists. The pale girl was so caught off guard that she didn't defend herself against the hands which tightened around her neck. She gagged out struggling for breath as she was lifted from the ground. The shock from the attack caused her to drop her bat.

"Do you… accept… I.O.U.'s?" the pale girl asked under her breath.

Buggy sneered before turning to his crew, who had just recovered from their beating. "Don't just stand there, you flashy dolts! Bring up the cage!"

"YES, SIR, CAPTAIN BUGGY, SIR!" the pirates cried out before heading to get a cage.

The pirates soon came back with a small cage that you'd have to crouch in to fit. Buggy carried the pale girl and dropped her into the cage. While she was coughing for her breath, they closed the door and locked it sealing her inside.

"Consider that a time-out." Buggy said.

"Hey, look. I'm sorry I honked your nose like a rubber horn."

Buggy growled. "Apology not accepted!"

The pale girl groaned. "Come on, man. I don't want any trouble. Just give me a ship and I'll be out of your hair."

"You don't have a ship?" Buggy asked. "Then how did you get her in Orange Town?"

"Well, I did have a ship. But it sank right when I came here. Too much damage from Reverse Mountain, I guess."

Buggy widened her eyes looking dumbfounded. "Wait. You came from the Grand Line, and you went over Reverse Mountain to get here to the East Blue?"

"Well, it wasn't easy. I had to avoid a giant whale first. It had scars all over its face."

Buggy groaned pressing his hand on his forehead. "You're not the brightest girl, are you?"

"What shall we do with her, Captain Buggy?" asked a sleazy man with light-green hair that covered half of his face along with a checkered scarf.

"Well, Cabaji," Buggy said, "Considering that this girl is more of a hinderance than a help, it's best to turn her in and collect a bounty. Someone, check out the wanted posters and see if she's worth anything!"

"I will, sir!" a random crewmate answered before heading into the galley.

"Would it help if I told you that I was really sorry about the nose?" the pale girl asked.

"NO!" Buggy shouted. "AND STOP TALKING!"

"I just want to help. Believe it or not, I used to be a trained therapist."

Buggy's dumbfounded look return. "You? A therapist? Yeah, and I'm Gold Roger."

"It's true. I used to be a specially-trained psychiatrist working for the Marines. If you have a problem, we can talk about it."

"I DON'T HAVE A PROBLEM!" Buggy shouted before slamming his fist hard on the table. He had underestimated the power in his fist, and didn't know until it was too late that he had broken the table with a single punch.

"Said the guy with the short fuse."

The crewmate who left before ran back as fast as he could. He had a piece of paper in his hand. "Captain Buggy, I found her! She's in the newest wanted poster!"

"Excellent. Let me see." Buggy said as he swiped the paper from his crewmate's hand. He read the text on the sheet out loud. "Let's see…. 'Harley Quinn. Wanted dead or alive. Bounty at…' Wait." He stopped reading to think for a moment. "Harley Quinn? Where did I hear that name before?"

Harley shrugged. "Perhaps you've heard of my work from my time with the Doflamingo Pirates."

"Doflamingo… WAAAAAAAHHH!" Buggy cried out in a panic. "YOU'RE THE HARLEY QUINN?!" Harley stuck out her tongue with a smile on her face. Buggy shuttered in fear. "BOYS, RELEASE HER AT ONCE!"

The pirates looked at each other in confusion. One of the crewmates was actually brave enough to ask, "Why?"

"I'll tell you why." Buggy said. "This girl is a high-ranking member of the Doflamingo Pirates. In fact, she's the girlfriend of Doflamingo himself, one of the Pirate Warlords, seven powerful pirates who work for the World Government and paid who take out even more pirates. They say that Doflamingo is just as powerful as he is unstable, so it's smart not to get on his bad side. So unless you want a Warlord to rain fire on you… LET HARLEY QUINN GO!"

Another pirate jolted up in fear before heading to the cage. He quickly reached into his pocket and looked for a key.

"A thousand flashy apologies, ma'am." Buggy said with a desperate face. "We've had a bit of a bad day. Someone stole a map from me and my nose got insulted too many times today. But believe me, if we had known that we were imprisoning a girlfriend of a Warlord, we would have…" Buggy paused and thought for a moment. He took another look at the wanted poster in his hand curiously. "Wait a minute."

At that time, the cage was finally open. Harley was finally able to stand up straight and stretch out her arms.

"Mmm. Finally. You know, you'd think a bunch of scallywags like you all could spring money for a bigger cage. Or at least a word search game. I'm just saying… OOF!"

Buggy surprised Harley by pushing her head down and squishing her back into the cage. He slammed the door shut and locked it again much to the crew's confusion.

"Hey!" Harley protested. "Make up your mind, you bozo!"

"I just need to clear something up first." Buggy said. "You're a member of the Doflamingo Pirates. You work for a Warlord. Not only that, you're a Warlord's girlfriend. And anyone that close to a Warlord should have immunity like he does. But if that's the case…" He held out the wanted poster. "Why is there a wanted poster with an active bounty on you?"

Harley leaned in to observe the poster which had her picture on it. She smiled at the text. "All right. So far, so good. I must say, I'm really… Wait, what?" Harley reached out and snatched the wanted poster from Buggy's hand to get a good look at it; specifically, the bounty, which made her upset. "Five million?! I'm worth way more than that and that jerk knows it! I bet he arranged for my bounty to be that low just to get under my skin. Well, I'll show him!"

"Uh… Show who?" Buggy asked.

"Doflamingo. Who else?"

Buggy looked more confused. "What? Why? I thought you worked for him, and that you were his girlfriend."

"Not anymore. I dumped that son of a bitch just a couple of weeks ago."

The Buggy Pirates stood still. They blinked a couple of times. Then, after a moment, they finally yelled out in surprise with their eyes bulging from their sockets. Even Buggy was surprised.

"YOU… DUMPED DOFLAMINGO?!" Buggy asked.

"Yeah. He was not happy about it." Harley said. "He even tried to keep me by his side by force. Thankfully, I gave him the slip, took one of his ships, and sailed off. Now, I'm free for some emancipation, and that's gonna start with building my own crew right here in the East Blue. Once I build a big enough crew, I'm going to return to the Grand Line and make a bigger name for myself than Mr. D ever could. I'm going to surpass that jerk and become the most feared pirate in the world!"

Harley's whole speech left the Buggy Pirates speechless. It was like they were hearing the story of a dead person coming to life and believing every word of it.

Harley smiled and looked back at Buggy. "So yeah. That's my whole story. So how about you let me out of this cage and let me have a ship? And hey, if you could also spare some crew members for me, that would be cool."

Buggy let out a little smirk before snickering. That snickering then became a loud laugh which confused Harley.

"Are you kidding?!" he asked. "There's no way I'm letting go someone as valuable as you! Here's the new plan. After my men bring a flashy end to the thief and take back my map, we'll head to the Grand Line and turn you in to Doflamingo. Once we bring you to him, we'll be on his good side, which will bring us loads of flashy benefits."

"You really like the word 'flashy', don't you?" Harley asked. "Also, IN YOUR DREAMS! ONCE I GET OUT OF HERE, I'M GOING TO KICK YOUR BUTT SO HARD, YOU'LL HAVE TO SIT ON YOUR EYES!"

Buggy snickered once more. "Tough talk, Ms. Quinn. But soon, you will…"

"Captain Buggy!" another pirate interrupted much to his irritation.

"What is it?"

"It's the thief. She's at the front gate. She wants in."

Buggy widened her eyes in shock. "What? What's she playing at?"

"We don't know, sir."

Buggy glared before giving his answer. "Very well. Let her in."

The pirates proceeded to open the gate. When it did, a teenage girl walked in with a teenage boy tied in rope. The girl was a young, pretty girl with orange hair. She had on a white shirt with blue stripes and an orange miniskirt. The boy she dragged in with her had on a red, buttoned jacket and blue pants and sandals, but his most distinguishing feature was the straw hat that rested on his head.

The orange-haired girl dropped the straw hat boy next to her and held out a rolled up piece of paper. "Captain Buggy, I have the thief you want. And here's the map too."

Buggy raised an eyebrow. "You're returning my map? What's this all about?"

"Blame it on my former boss here." The girl pointed at the tied up kid next to her. "He and I had a heated argument. He's an idiot, so now, I'm wanting to join you."

Buggy froze for a moment before letting out a loud roar of laughter. The rest of the crew joined in while Harley looked confused, an emotion she noticed that she shared with the boy in the straw hat.

"You've certainly got spunk, kid!" Buggy complimented. "What's your name?"

"Nami."

"Well, Nami, you certainly made the right choice." Buggy said. "All right. I'll let you join. Welcome to the Buggy Pirates."

The rest of the pirates raised their glasses to celebrate. After a long sip, a couple of them grabbed the straw hat boy and threw him in the same cage as Harley. They locked it quickly so neither of them could escape. All they could do was sit there while everyone around them partied.

Harley's eyes shifted to the boy in the straw hat and gave a curious look. "Hi. I'm Harley Quinn."

The straw hat boy looked back and smiled. "Sup. I'm Luffy. Nice to meet ya."

"So what's going on?" Harley asked.

"Honestly, I'm not entirely sure myself." Luffy said. "It all happened so fast."

"Well, it looks like we're in this sticky wicket together, kid." Harley said. "We've got to find a way out of this mess before it gets worse."
