A Final Challenge? The Man on Raftel

It was 20 years ago when Gold Roger was executed in Lougetown and ever since then the Great Pirate Age began. Everyone who wanted to find Gold Roger's legendary treasure One Piece set out to sea, to conquer the New World like Gold Roger did before. After 20 years one crew of pirates were able to conquer the New World and were finally able to land on the last island on the Grand Line, Raftel. That crew was the Straw Hat Pirates led by the idiotic, lovable rubber captain, Monkey D. Luffy.

"YAHOOOOOOO!! We finally made it." Shouted the captain of the Straw Hat Pirates. Luffy was already on the land of Raftel as he had his huge grin plastered on his face. He had his trusty Straw Hat on his head as he looked from side to side with eyes full of excitement.

"Oi Luffy, calm down already." Zoro said to Luffy as he caught up to his idiotic captain. Zoro was Luffy's first mate and has been ever since their encounter back at the marine base led by Captain Morgan. Zoro had three swords, one was a blade called Shunsui which he received after defeating Ryuma back at Thriller Bark , the other was the strongest blade in the world which he received from Hawkeye Mihawk when he defeated him to become the best swordsman and the last blade was his trusty old Wado Ichimonji, which he received after Kuina's death from his childhood.

"Seriously Luffy, why are you always so excited?" Nami told him. Nami was the crew's navigator and the worlds greatest. Nami hated pirates, but Luffy was able to get her to join his crew after helping her get rid of Arlong, who was terrorizing her village. Arlong was also the person who killed her foster mother Bellemere.

"Well, why he wouldn't he be?" Usopp spoke up. Usopp was the marksman of the Straw Hat Pirates. Usopp is also a huge lie, which sometimes helps him defeat his opponents, key word "sometimes". Usopp also beat his father in a shootout when Luffy and the crew met Shanks and his crew during their adventures in the Grand Line. Usopp also visited the Elbaf during their travels and was able to see the giant warriors and become a great warrior of the sea as well, even though he sometimes chickens out.

"Nami-swan, you were so fantastic navigating through the storm to get us here." Sanji exclaimed in his love state. Sanji is the love-cook of the Straw Hats. His cooking is the best the entire East Blue has to offer and was the apprentice of a former pirate, Red Leg Zeff. Sanji is kind hearted, but can also be ruthless especially with his chivalry. His dream was to find the legendary sea the All Blue, which he happened to find before they arrived on Raftel. He was able to catch a lot of fish from the sea and was able to get a ton of dishes done for the entire crew.

"This is so cool, I can't believe we made it." Chopper the blue nosed reindeer said. Tony Tony Chopper was the ship's doctor and a very good one at that. He was able to help the crew in curing illnesses they experienced and help heal their battle wounds, mostly Usopp's. Chopper was able to study and find cures for a lot of illnesses during his adventures with the crew and still continues to find ways to heal every illness there is. Chopper has also eaten the Hito Hito no Mi Fruit which gave him the power to transform into different transformations. He also created the Rumble Ball, which allows him to transform into his other seven transformations.

"Ee it is." 'Hopefully what I'm looking for is here.' Robin thought. Robin is an archeologist who had a bounty put on her at the age of eight. She is able to read the language written on the ancient poneglyph stones and she also ate the Hana Hana no Mi Fruit which allows her to create any part of her body on any surface including herself and other humans, which helped the crew in many situations.

"This is so SUPER!!" Franky shouted doing his pose. Franky is the crew's shipwright and the one who built the crew's ship, The Thousand Sunny. Franky is also a cyborg who was the apprentice of a famous shipwright that built the Pirate King's own ship. Franky was injured badly while trying to stop Tom's Train from importing Tom the shipwright to his execution and suffered fatal wounds. However he was able to turn himself into a cyborg that helped the crew take down the CP9.

"Yohohoho, I can't believe my eyes that we are finally here. BUT I HAVE NO EYES!! Skull Joke." Brook shouted. Brook is a musical skeleton who encountered the Straw Hats during their adventures in Thriller Bark. Brook had his shadow taken by Gecko Moria, but was able to retrieve when Zoro defeated Ryuma. Afterwards, Brook joined the Strawhats hoping he would one day be reunited with Laboon the whale, which he and his former crew promise to meet one day.

"One Piece! One Piece! Where is One Piece!? Is it there? Or there? Maybe over there?" Luffy wondered as he looked in every direction while being hyperactive.

Nami walked up to Luffy and hit him in the head to calm him down. "Baka! Calm down we'll find One Piece eventually."

"But where could it be?" Usopp wondered.

"Well it has to be hidden somewhere in the middle of the island since that's where most of the treasure is." Nami told them.

"Ah Nami-swan, when you think you are amazingly beautiful." Sanji told her in his love state.

"Idiot cook." Zoro muttered.

"What was that marimo?" Sanji replied angrily.

"Nothing, I just said you're a prince..." Sanji smiled as he turned to admire Nami until, "of Gay Kingdom." This comment caused Sanji to kick Zoro, but not before the swordsman blocked his attack with his sword. Nami however stopped their fighting by punching them both on the head leaving them with bruises.

"Knock it off, Bakas!" She shouted at them. Zoro groaned in pain while Sanji was still admiring Nami with heart eyes.

"Navigator-san?" Robin called. "In order to find One Piece it will be better to split up and search the island."

"Robin-chwan, that was a beautiful idea, but not as beautiful as you!" Sanji shouted with heart eyes.

"Un, so I guess we'll split into three groups of three then. It would help us cover more ground." Nami suggested.

"Great idea, Nami, but how do we pick the groups?" Chopper asked.

"Not to worry about that." Usopp spoke up as everyone turned to him. He reached inside his bag to reveal nine pinballs, but there were three different colors. Three of the pinballs were red, the other three were green and the last three were yellow. "Alright mina, we each pick one of these pinballs and whoever has the same color will be the team."

"Wow Usopp, that's a great idea!" Chopper said with eyes full of amazement.

"Yosh, lets pick already." Franky shouted as he walked up to Usopp and watched as he mixed the nine pinballs in a bag and finally gave the bag to Franky. Franky picked out a pinball and held it in his palm with a closed fist. Usopp then went to every other crew member as they also picked out a pinball out of the bag. When Usopp picked out the last pinball everyone revealed their selection and theses were the teams.

Usopp, Chopper and Robin

"Yosh Chopper lets find out where One Piece is located before everyone else does." Usopp declared.

Chopper jumped up and down in excitement, "I can't believe we'll find the One Piece."

Robin just smiled down the reindeer doctor as he continued to jump up and down in excitement.

Sanji, Zoro and Brook

"NANI! WHY THE HELL AM I WITH MARIMO!?" Sanji shouted in front of Zoro.

"BAKA! I DON'T LIKE IT EITHER YOU LOVE COOK!" Zoro shouted back.

"Yohohohoho, can't we all just get along?" Brook asked cheerfully.

"STAY OUT OF THIS!" The both shouted at Brook.

"Yohohohoho, my ears are going to bleed if you keep on screaming, oh wait I don't have any ears, Skull Joke."

Luffy, Nami and Franky

"Why am I stuck with this baka!?" Nami asked noone in particular.

"This is so SUPER! Hey Mugiwara lets go find that One Piece." Franky told Luffy as Franky did his star pose.

"Alright Franky, lets go!" Luffy told him as they began to walk away.

"Oi, Nami where is it?" Luffy asked stopping in his track and turning toward her.

"Baka! Like I know where the hell it is!" Nami shouted at Luffy.

"Navigator-san, we'll head this way." Robin told her as she, Usopp and Chopper began to walk away in a random direction.

"Un, okay Robin." Nami told her as she watched them off.

"Then we'll go this way." Zoro told her as he began to drag Sanji with, who was complaining about why he couldn't go with Robin or Nami.

"Yohohoho, good luck on your side." Brook told her.

"Just don't get lost Zoro!" She told him.

"URUSAI!!" Zoro shouted back.

"Yosh Nami, lets go." Luffy told her as he began to walk with Franky in a different direction from the others.

"Chotto matte!" She shouted as she ran up to Luffy and Franky.

After a while of searching...

"One Piece, where is the One Piece?" Luffy complained.

"We've been searching for hours and not one sign of anything that looks like it can have the One Piece." Franky said as he looked around.

"I wonder if the others have found anything." Nami wondered.

Zoro, Sanji and Brook

"Oi, where did that marimo go?" Sanji wondered.

"Yohohoho, it looks like he's lost again." Brook commented.

"That bastard is really a big idiot." Sanji said to noone in particular. Just then they suddenly heard something in a nearby bush. "Oi, who's there?"

Out of the bush came out Zoro who had been looking for them, "Oi, there you guys are, how could you guys get lost?"

"BAKA! YOU'RE THE ONE WHO GOT LOST!" Sanji shouted at Zoro.

"What was that Curly Brow?!" Zoro shouted back as they began to bicker, again.

Meanwhile, Brook sat down on a boulder and began to drink his tea. "DON'T DRINK YOUR STUPID TEA!" Zoro and Sanji both shouted.

"Yohohoho, I wonder how everyone else is doing." Brook wondered ignoring the two.

Usopp, Chopper and Robin

Usopp and Chopper were walking happily with Robin right behind them. "Yosh it's time for the brave Captain Usopp, to find the One Piece and become Pirate King."

"Long Nose-kun, isn't it supposed to be Captain-san who'll become Pirate King." Robin said.

"R-right, anyway lets find the treasure before everyone else does."

"How do we do that?" Chopper asked.

"It will be just like the time I found the Great Pirate Woonan's treasure back in the East Blue." Usopp told Chopper who just looked at him amazed.

"Really!!" Chopper asked excited. (Woonan was a pirate from One Piece The Movie.)

Robin just smiled and chuckled to herself as she looked up to the sky. 'I wonder where the Rio Poneglyph is?'

Luffy, Nami and Franky

"Are?" Luffy questioned as he, Nami and Franky looked in front of them to see a cave that was dug inside the big mountain.

"Masaka, you don't think the One Piece is here?" Nami wondered.

"Well, it's the closest thing we found that could have the One Piece in it." Franky told her.

"Well, it's better than anything. Franky blast a missile in the sky to tell the rest where we are." Nami ordered Franky.

"Yosh!" Franky pointed his left arm into the sky as his hand began to rearrange into a missile launcher. "Weapons Left!" Franky shouted as a missile was shot out of his arm and into the sky.

The rest of the crew saw Franky's missile explode in the air and began to had towards it. When they arrived they saw Luffy, Nami and Franky standing in front of a huge cave.

"Oi, Nami-san, is this where?" Sanji asked.

"We don't know, we didn't go inside yet." Nami told him and the rest.

"So, this might be the place where One Piece is located." Zoro said.

'It could also be the place where the Rio Poneglyph is located.' Robin though as she looked at the cave's entrance.

"Yosh lets go!" Luffy declared as he entered the cave followed by his crew.

Inside the cave, it was completely dark so Franky took a piece of wood and lit it on fire with his Fresh Fire attack. Luffy's heart was thumping in excitement as his long life dread was about to come true.

"How long is this cave?" Usopp wondered.

"Who know it could go a long way." Zoro told him.

"Mina, look its light!" Luffy shouted as he noticed a light coming from the end of the tunnel. "Yosh, One Piece here I come." Luffy shouted as he began to run toward the light.

"Chotto matte Luffy!" Nami shouted as she and the rest of the crew began to run as well.

When Luffy arrived at the end of the tunnel, what he saw was not what he expected. The rest of the crew caught up to him and were shocked as well. In front of them was a huge door made out of gold. It had a dragon doorbell on both the doors and was easily crafted by an expert. However, the most surprising part was that there was a man leaning on the door looking at the crew.

"Nani? Who the hell are you?" Luffy asked.

"Welcome Straw Hat Pirates, to the island of Raftel." He told them. "Are you ready to accept your Final Challenge?"

Well how do you guys like it, this is my first story so read and review. Also at the end of each chapter I will have a spoiler for you, kinda like what they have after each One Piece episode.

Zoro: He looks suspicious, I don't trust him.

Usopp: But what the hell is a human doing on Raftel?

Franky: He might be someone from Gold Roger's Pirate crew?

Usopp: You think?

Luffy: Well whoever he is, I'll just kick his ass.

Nami: But what the hell did he mean by a Final Challenge?
