A/N: This is my One Piece fanfic with an OC to join the Strawhats, hope you enjoy. Since Summer is here, hopefully more coming soon. I will be basing the arcs off of several theories from the Oro Jackson website and will be adding my own spice to it.

Chapter 1: Saoce D. Kale

The Strawhats were in the middle of partying, they'd just defeated Kaido with the help of Law, X Drake, CP9, Jinbe and Tashigi. Zoro and Nami were drinking with Blueno and Jabura, Luffy and Law were dancing to Brook playing Binks Sake and Lucci was sitting quietly in the corner. Tashigi had taken off back to Marine HQ to deliver a report and X Drake was preparing to leave in the morning. Usopp was at playing with Chopper and Franky, Sanji was cooking and Robin was reading, but giggling at the others antics. Luffy jumped up on a table, "OI! We beat a Yonko! Two down! Two to go!" (A/N: At this point they will have already defeated Big Mom.) Law raised a glass to this, everyone celebrated. Luffy went back to dancing and singing along with Brook.

Jinbe was out on deck looking up at the stars when Lucci walked out. "You. Fishman, what are you doing out here by yourself?" Lucci asked casually. Jinbe turned slightly to face him, "Nothing, just thinking." Jinbe replied. Lucci kept his usual stoic expression and turned to leave to X Drake's ship. "Well Strawhat is looking for you... Geppou!" Lucci said as he took off using Geppou. Jinbe went inside and Luffy immediately ran to him, "Jinbe! So are you ready to join my crew now?" Luffy asked. Jinbe smiled and nodded, "Yes Luffy... I am." Jinbe replied. "YOSH!" Luffy shouted as he went back to dancing. Jinbe had a deadpan expression at how Luffy was acting, but decided to just sit down and enjoy himself.

Meanwhile...

A dark, ghostly forest surrounded a young man. His name was Saoce D. Kale. Kale wore a long black trench coat with his hands in his pocket, he had shoulder length black hair and each of his eyes had a different colour, his left eye was blue and his right eye was red. He had a large scar all the way along his bare chest, he had three pistols on his belt and a sword by his side. He walked slowly down the path in the forest while slowly whistling a sea shanty. He had just finished clearing an entire village of pirates and had collected their bounties. He had to, he was being forced to by another pirate. He had to give eighty-five percent of the bounty to his "captain" in order to save his mother's life. His mother, Saoce D. Lily, was being held captive by the captain. The pirates name was William Saul. His bounty was five hundred million beri. Kale couldn't wait for the day that he and his devil fruit power could kill that bastard and rescue his mother. But he had to wait... His next target for William was... Monkey D. Luffy. He had observed the Strawhat Pirates' recent exploits and decided that attacking them head on would be suicide... He need to gain their trust and to infiltrate them. He needed to become a Strawhat pirate.

The next day...

X Drake had taken off with CP9, Law was sailing closely behind The Thousand Sunny. Both Law and Luffy both still had to take down Blackbeard and Shanks. X Drake he would help as soon as he sorted out some business of own, Luffy and Law would welcome him. "Hey Luffy, we're running low on water and some food. We need to stop at the next island and get some supplies." Nami advised him, Luffy nodded in response and picked his nose. "How far until the next island?" Chopper chimed in. Nami glanced down at her log pose, "about twelve miles." She responded. Usopp was on top of the mast with a telescope, "Guys! I see the island in the distance!" Usopp shouted, and came down from the mast and ran to the front of the ship, almost slipping on the deck. "Set sail!" Usopp shouted. Luffy glared a little at Usopp, "I say that! Not you!" He protested. Nami looked annoyed, "Will you two cut it out?!" She nagged. Sanji walked out of the kitchen and handed her some tea, "Here you guys Nami-Swan!" He declared, hearty eyed. She smiled, "Thank you Sanji!" She thanked. Sanji went back to the kitchen, Chopper was in the garden making medicine while Robin was under a parasol reading a book.

After a couple of hours the Strawhats docked at Puru Island to get supplies. Robin and Nami took off to the town centre to get materials, Sanji went to the market to get food, Franky and Usopp went to buy some wood and metal, Zoro, Luffy, Brook and Chopper went to get water from a local store. Jinbe decided to stay at the ship and guard it. Chopper went into his Strong Point to lift the barrel he was carrying. Luffy's stomach rumbled, "Oh... I'm soooo hungry!" Luffy whined, Zoro furrowed his brow in annoyance. "You've been saying that for an hour now! Why don't you just go to a bar and get something there!?" Zoro shouted. Luffy grinned and nodded, "Great idea Zoro! I'll do that!" Luffy said as he dropped the barrel he was carrying and took off. "Wait! I meant after we brought the barrels back!" Zoro shouted after him, but it was too late, Luffy was gone. Zoro growled and just stacked Luffy's barrel onto his and continued walking.

Luffy had soon made it to a bar and was devouring the food that he bought, just as Luffy was sitting at the bar Kale walked in. He didn't notice Luffy and just calmly sat down at the bar and got a drink of sake. As he calmly drank Luffy turned to him. "Hey! Do you live here? My friends and I are looking for a good place to get supplies?" Luffy asked with his mouth full. Kale contorted his face in disgust, "No, I don't live here. Why don't you ask-" Kale stumbled over his words when he saw who he was talking to. 'Ok... It's Strawhat... Just as I rehearsed. Try and join his crew!' He thought. "Hey, you're Strawhat Luffy! I'm a big fan! Kale pretended to be starstruck. Luffy grinned and chuckled, "Yup! And I'm gonna be King of The Pirates!" Luffy stated. Kale grinned and nodded, "I have no doubt that you will be, especially after taking down Doflamingo, Big Mom AND Kaido! You're amazing!" Kale shouted. Luffy nodded as he shoved more food down his throat. Kale got off his stool and got on his knees and bowed his head. "Strawhat Luffy, let me join your crew!" Kale pleaded. "No." Luffy blankly stated. Kale had a shocked expression, "W-What? Why?!" Kale demanded to know. "You don't look strong." Luffy said. Kale looked offended, "I am strong!" Kale shouted. "You don't look it, I need strong Nakama. Not weak ones." Luffy replied. "If I prove I'm strong, then will you let me join your crew?" Kale asked. Luffy thought about it for a second, "Hmm... Ok!" Luffy said. Kale cracked his knuckles and smirked, "Alright! I'll fight anyone, name one person!" Kale said. "How about you fight with Sanji? He can test if you're strong!" Luffy gleefully said. Kale smirked, "Black Leg Sanji? Fine, I'll fight him!" Kale replied coolly. "Ok, let me finish my food and then we can go find him!" Luffy suggested with his cheeks full of food.

It took an hour for Luffy to finish all his food but he was finally finished and they left the bar to find Sanji. "So, where is he?" Kale asked. "I don't know" Luffy blankly replied. Kale looked annoyed, "What do mean you don't know!?" Kale demanded to know. "We went to different places to get supplies." Luffy replied. "Well, where do you think he could be?" Kale asked. Luffy shrugged, "We can try the ship... He might be there." Kale nodded, Luffy took off. "Wait! Hold on for me!" Kale shouted as he chased after Luffy. He caught up with Luffy at an alleyway, Luffy looked around. "Uh... I'm lost." Luffy said. Kale had a deadpan expression on his face, "What do you mean you're lost?! Don't you remember where you docked your ship!?" Kale asked, Luffy shook his head, "Nope." Luffy flatly stated. Kale facepalmed, "You really seem useless." Kale said. Luffy frowned, "That's not very nice." Luffy replied. Luffy kept strutting on his way to find the other Strawhats. 'My god this guy is an idiot!' Kale thought. "Don't you have Haki to sense your crew?" Kale asked. Luffy's face lit up, "Oh yea! I forgot! Gimme a sec." Luffy concentrated for a second and then he relaxed, "Follow me!" He shouted as he took off. Kale chased after him.

Luffy stopped at the harbour and the Thousand Sunny in front of him, Kale slowly approached from behind. "Wow! You can keep up with me! Maybe I was wrong about you." Luffy said. Zoro jumped off of the deck of the ship and smacked Luffy over the head, "You abandoned us!" Zoro shouted, Luffy rubbed the sore part of his head and groaned, "I was hungry!" Luffy retorted. Zoro growled at Luffy, "You coulda waited until after we brought the water back!" Zoro scolded. Luffy ignored him, "Zoro, have you seen Sanji around?" Luffy asked. Zoro sighed at how dense Luffy was, "He's in the kitchen.." Zoro conceded. Luffy grinned and turned to Kale, "You wait here." Luffy stretched his way onto the deck of the ship to go get Sanji. "Who are you?" Zoro asked. Kale turned to him, " I'm Kale." Kale replied. Zoro rolled his eyes, "What did Luffy drag you into?" Zoro asked, Kale shrugged, "Nothing. I asked could I join the crew, Luffy said that if I prove that I'm strong I could join." Kale said. Zoro narrowed his eyes and sighed, "It's just idiotic how easily he trusts people." Zoro stated. Kale nodded, "True, I got a taste of his idiocy on the way here." Kale replied. Luffy jumped down with Sanji. "This the guy?" Sanji asked. Luffy nodded and grinned. "So all I have to do is hold my own against Black Leg Sanji? Then I can join?" Kale asked. Luffy nodded, "Yep. But no cheating." Luffy added. Kale nodded and got into a fighting stance, Sanji lit his cigarette as flames appeared at his feet, "Let's get this over with, I gotta finish making Robin-Chan's dessert." Sanji stated. Kale's arms began to get covered in Busou Haki, "Let's dance, Black Leg Sanji!" Kale announced as they charged at each other...

A/N: And there's chapter 1, yes, the next chapter will be the fight and a little more. But I hoped you enjoyed this, see you later ~Ryan.
