Cross over : One Piece / Pirates of the Caribbeans

Summary : Still another pirate wants to be known as the Pirate King. But when he sends Zoro, Shanks and Mihawk, in the well know sea of Caribbeans, and when they meet with a certain Jack Sparrow... Well hidden secrets will be revealed, as our heros struggle to find a way back home. Especially since this "captain" Jack Sparrow doesn't seem to be done with all kinds of curses.

A/N : This story will be taking place in both the PotC and OP fandoms. Jack Sparrow will appear in the second chapter. Speaking of which, it will be the same deal as usual ; short chapters, but frequent updates. English isn't my first language, I might make mistakes. But I now have a beta, starting at chapter 21. Thank you Hikaru !

Well, that's all, enjoy.

Chapter 1

Juraquille "Takanome" Mihawk stepped outside and yawned. He idly realised it was the middle of the afternoon, and way too late to be just waking up, but that kind of details hardly mattered when Shanks was there. The man could drink astonishing quantities of alcohol, and his endurance was unbelievable. Not that Mihawk wasn't a match for him. However, they still had to sleep from time to time, and that meant they usually woke up at weird hours. But, since they were about the only living beings on this island, that was of little consequence.

"Takanome !"

Alright, so, they had been the only living beings on this island. Seemed like there was now another one. Mihawk turned to face the newcomer, and he narrowed his eyes. Weird green hair. Three earrings, matched by three katanas. A black bandana. That could be only one man in the world ; Roronoa Zoro, the only one to have challenged Mihawk and lived to tell the tale. Well, one of the two, including Shanks, but that didn't really count.

"What do you want ?" Mihawk asked him with assumed boredness, although he already knew the answer, slightly annoyed at this interruption of what might be called "holidays".

"I am the best swordsman in the world, and I am going to prove it", Zoro replied unsurprisingly. He had not yet drawn his katanas, but that was a matter of time.

They stood there, facing each other. Mihawk hadn't really been expecting that fight to happen so soon, but now that Zoro had come to challenge him - a second time, at that - he wasn't going to refuse. And this time, there would be no games with his ridiculously short knife.

"Oi, Takanome ! I didn't know you invited a friend !"

Mihawk didn't have to turn his head to know who had just spoken. He heard the crunch of the sand as his lifelong red-haired friend stepped out of the log cabin they had been using for their "holidays".

"I didn't invite him, Shanks", he replied, still motionless.

"Oh ?" mild curiosity could be heard in the pirate's voice. He fell silent for a second, as though trying to remember something. "I've seen his face somewhere..."

"You would", Mihawk reluctantly admitted. "He's a member of your little friend's crew. Roronoa Zoro."

"Now that you mention it..." Shanks nodded, as he came on Mihawk's side and sat on a log, out of both swordsmen's way - merely watching. Zoro hardly spared him a glance. "He challenged you", the red-haired pirate added. "Do you intend to pick up the gauntlet ?"

"Of course", Mihawk snorted.

Zoro muttered something that sounded awfully like "took you long enough", and at last drew his three katanas. Mihawk watched in mild interest. The younger man's santouryu was an interesting - and deadly - technique. He wouldn't have thought possible to fight efficiently with three katanas without getting in a muddle, but Zoro somehow managed. There probably were countless hours of training behind this unique style. Now, they would see which of their blades cut the sharpest.

The fight started as fast as suddenly. A moment, Zoro was there, still ; a second later, he was on Mihawk, attacking from three different directions. But the more experienced swordsman had seen him coming, and hadn't waited idly for him. His oversized sword seemed to be everywhere at the same time, as he fended off Zoro's assaults, with what seemed like effortless ease. His foe had gotten better - much better, Mihawk had to admit. But when he would stop defending himself to start his own attacks, that would be the end of Zoro.

However, the fight didn't have a chance to get that far, for yet another intruder stepped on the previously quiet island.

"Oh, bravo, bravo !" the man exclaimed wholeheartedly. "Such a display of skills ! I'm impressed."

Both Mihawk and Zoro broke off their attacks, in favor of facing the unknown, possibly threatening, newcomer. He had interrupted their fight, and none of them was pleased by that. Not to mention, this stranger had nothing to do on the island - more an atoll than a real island, really, but that was out of place.

He was a tall, lean, brown-haired man, with what would have been average features if half his face hadn't been... well, it was difficult to know what might have happened to him, but that left side was a nightmare of scarring tissues and hideous marks. That made it difficult to know his age, but he was probably in his thirties or early forties, with early, pain-induced wrinkles.

"Oh, I didn't mean to interrupt", he said with a mocking smile.

"Who are you ?" the voice was Shanks', for none of the two swordsmen seemed to be in a talkative mood.

"Ah, yes. So rude of me, I forgot to introduce myself... My name is Alex Winslow. And I am the Pirate King."

Three eyebrows rised at this chancy assertion, that nothing seemed to back up. The beach was a bit further, so it was not possible to see the man's boat, but he certainly seemed to have come all by himself. Without a crew. Not the kind of things the Pirate King would do, was it ? However, that didn't seem to hinder Winslow's rant.

"I see you are unconvinced. But, you see, the problem is, I do have the power to be the Pirate King, only no one knows that yet, and I don't want to waste years getting all these people off my back. So, that means I have to strike hard for my first time. Getting rid of Roronoa Zoro, Takanome Mihawk, and Akagami Shanks, all in one hit, should do the trick, don't you think ?"

Shanks stood up and smoothed out his clothes. He had thought that intrusion was Mihawk and his rival's business, but that was now obviously his problem too.

"And you think that you can take the three of us, all by yourself ?" the red-haired pirate's voice was politely incredulous.

"Oh, I don't 'think'. I know I can do it - you'll see, when you fall through my golden triangle."

The three other men shared a glance.

"Your golden what ?" they asked all at the same time.

Winslow laughed, and it was not a pleasant sound. He raised his hands, and directed them towards the other pirates. They were empty, and yielded no obvious threat. However, a tremor seemed to run across the ground, and a faraway sound became audible. The air shivered around the three men, red, dark and green-haired. Then, there was a flash of light... and nothing.

"Nami ! I want to go to the Saikai island !"

Another whim of Luffy's, Nami thought as she climbed down on the deck. Not that she wasn't used to his complete lack of common sense. Oddly enough, that was that same foolishness that had saved them numerous times in the past. She was through trying to understand that.

"Why do you want to go there ? It's a small island, with just a town - there's nothing of interest there", she still asked as she unfolded her maps.

"Zoro told me he'd meet us there."

"What ?"

Now that she thought of it, it had been a long time since she last saw this crazy swordsman. She had not noticed before, buried as she was in her maps and cartography. Ah, she knew the atmosphere was too blissfully quiet to be natural.

"And why isn't Zoro with us ?" she queried with annoyance.

"He's gone to challenge Mihawk", Luffy answered with this Cheshire cat smile of his. "When he's back, he'll be known as the greatest swordsman of the world !"

"Or dead !" Nami shouted, truly irate now. "Why in the world did you let him do that ?! You should have bound him to the staff if need be !"

She couldn't see Luffy's face, hidden as it was under his straw hat's shade, but he suddenly seemed much more serious. And, well. More adult. As much as Luffy could be anyway.

"But, Nami... That's his dream. I had no right to interfere."

The young woman heaved a dispirited sigh. It was no use arguing with Luffy when he was like that.

"Off to Saikai island, then", she said with an obvious lack of enthusiasm.
