On the ship of the Whitebeard Pirates

The night was not a calm one. The ship of the Whitebeard Pirates, the Moby Dick, had been caught in a serious storm. The dark skies covered as far as the horizon and it was total darkness on the ship. The occasional strike of lightning would brighten up the surroundings, revealing Whitebeard Pirates manning the Moby Dick and trying to prevent it from capsizing. The wind arose and it pushed the ocean into mountains of angry waves.

There were many Whitebeard Pirates on the deck running around, ensuring the the Moby Dick would survive through this storm. A ship this big would require a lot of manpower, after all. There were dozens of men from all divisions furling the sails, and another dozen manning the rudder, while many more were trying to help.

At the bow of the ship sat one of the strongest men in the world, captain of the Whitebeard Pirates, Edward Newgate. To his right was the Commander of the 1st Division, Marco the Phoenix, while to his left was the Commander of the 2nd Division, Fire Fist Ace. Contrary to the panicked Whitebeard Pirates on the deck, these three were eerily calm, as if they treated a storm so huge as nothing to be worried about.

Marco was peering out the side of the Moby Dick, staring at the monster waves that were relentlessly hitting at their ship. "Hmm, the waves seem to be extra angry tonight-yoi" he commented.

"Ah, gotta take it all in stride as a pirate," Ace replied with a smile.

"Guararararara! I have been through storms that were much worse than this! This should not be a problem at all!" laughed Whitebeard.

As the three continued their conversation, the rest of the commanders were also helping the crew to stabilize the ship in this storm.

"Eh, is that a kid in the middle of the ocean-yoi?" Marco suddenly asked.

"Don't be ridiculous, why would a kid be in the middle of the ocean in such a huge storm?" Ace replied skeptically.

"Oi, Pops. Check it out, it really is a kid." Marco insisted to Whitebeard.

True enough, the sight which greeted Whitebeard was indeed as Marco had said. A kid was clinging onto a piece of wood, and he seemed to be unconscious. The strong waves were washing over him every passing second, and with each hit he took from the waves, he seemed to sink deeper into the ocean. It was evident that if it continued, the kid would drown in no time.

Whitebeard narrowed his eyes at this sight. Pirates or not, he had morales, and he would not let a kid die under his watch. "Marco, pick him up and bring him to the ship," Whitebeard commanded.

Marco nodded in acknowledgement and immediately partially transformed into his phoenix form. Blue and orange flames licked the air around him as his arms turned into wings. He jumped off the ship and made a beeline for the kid.

As Marco soared over the kid, he hooked his legs around the kid and lifted him up, before swooping back to the where Ace and Whitebeard was. He laid him on the floor and it was revealed that the kid was a male.

"What do we do with him now-yoi?" Marco asked Whitebeard.

"Bring him to the sick bay for Lea to patch him up, before we see what to do with him," Whitebeard decided.

As Marco touched the boy to lift him up, the boy suddenly started to twitch violently. Marco was immediately put on alert. Whitebeard and Ace merely looked on in curiosity.

The boy began to undergo an intriguing transformation. He began to grow in size as bulging muscles started to appear on his arms, legs and torso. Two holes appeared on both sides of his spine and wings started to emerge from it. The wings were humongous, bigger than the original size of the boy. They were black and it had a resemblance to bat wings. When the boy looked up, his eyes were a bloodshot red and appeared to be in a glare.

This boy… He has the power of the devil itself! Whitebeard realised.

"Marco! Get everyone below deck now! This boy is dangerous!" Whitebeard ordered.

Marco complied immediately as he knew how serious it was when Whitebeard called someone dangerous. He swooped down to the deck in his phoenix form and began to get everyone below deck despite the storm still going strong.

The boy looked up and stared into Whitebeard's eyes. Lightning striked and a loud clap of thunder was heard, before the boy disappeared and reappeared in front of Whitebeard. The boy moved as fast as the wind, and as he was right in front of Whitebeard, his bloodshot eyes turned redder, ready to launch an attack.

Whitebeard narrowed his eyes and was prepared to counter the attack with a blow of his own, when suddenly, "HIKEN!" A pillar of flame was shot towards the boy and it caused him to go flying backwards, crashing into the railings of the Moby Dick. Ace had sent a blow towards the boy upon seeing his hostile intent.

"Very well then, Ace. I'll leave this fight to you. Don't injure him too much, the boy's valuable," Whitebeard said.

Ace grinned as he lifted up his orange hat with a burning finger. "No promises though, Pops."

The boy was not about to be taken down so easily. He stood up and glared at Ace with his bloodshot eyes. PEW! Laser beams suddenly shot out from the boy's eyes towards Ace. Ace saw the attack coming and jumped out of the way. However, the railings of the ship behind Ace was blown over the ship and it disappeared from the surface of the ocean.

The boy was relentless in his attacks as he rushed Ace. He launched a flurry of punches, all of which were blocked relatively easily by Ace. Ace then counter attacked by sending a high kick aimed at the boy's head. The boy was able to block it with his right arm, but the impact pushed the boy backwards a little.

As the boy lowered his arm, he saw Ace charging at him with bright orange flames licking his whole body. The boy raised his right hand and created a ball of dark energy, and shot it at the charging Ace. Ace saw it coming and jumped over the attack easily. "ENTEI!" Ace roared as he launched a flaming uppercut at the boy. As the punch connected with the boy, flames suddenly erupted and engulfed the boy. The boy flew a great distance backward and slammed into the side of the Moby Dick before slumping to the ground, smoke emerging from his mouth.

The boy began to revert back to his original form. His wings became smaller and disappeared, his muscles became smaller, and he began to resemble a normal boy of fifteen years old again. The boy lay on the ground unconscious, with the rain splattering all over his back.

"Pops… this boy radiates a demonic aura. I felt it when I came into contact with him," Ace whispered.

Whitebeard narrowed his eyes and replied seriously, "I know. This boy has the Power of the Devil himself. If brought up incorrectly, he has the power to singlehandedly bring down the world. This boy may not be able to control it and use the power to the fullest as he is still very young, but he is very valuable. We cannot allow him to fall into the hands of people with wicked hearts. They'll use his power and cause chaos and destruction. Take him to the sick bay, we'll see what to do with him after he wakes."

Ace nodded and lifted the boy up and slung him over his shoulder, and left for the sick bay.

After Ace had dropped off the boy at the sick bay (with a huge telling off from Lea about him being so severely burnt), he went to the dining room as Pops had called a meeting for the ship's elite commanders. Whitebeard, Marco, Ace, Jozu - the third division commander, and Thatch - the fourth division commander, were present at the meeting. The commanders could all sense the suspense from Whitebeard with their Kenbunshoku Haki and knew that this meeting was going to be a very serious one.

"Today, we are here to discuss about the boy," Whitebeard began.

"You said something about him being dangerous earlier," Marco said.

"That's right," Whitebeard nodded, "that boy harnesses a great power, one that can literally destroy the world on its own. Marco, Ace, you saw when the boy changed into a monster right?"

Marco and Ace nodded, having witnessed the boy's transformation into a devil.

"That was caused by the Power of the Devil, a frightening power that can wipe off everyone from the face of the earth by itself. This power is not to be underestimated. This boy, he is still young and inexperienced, thus he is not able to achieve the full potential of that power. However… it might be a different story once he grows up."

"Pops… Why are you speaking as if that power is one of the worst things that could happen to this world?" Thatch asked.

Whitebeard replied seriously, "Because it is. I have fought against a person who utilised this power to near perfection, and it was not a pleasant experience."

The four commanders settled themselves comfortably into their chairs, knowing that Whitebeard was about to go into storytelling mode.

Twenty Years Ago, on an island in the New World

Whitebeard, known as Edward Newgate at that time, had just docked on a new island. He was already known as one of the strongest men in the world, and he had recently been contacted by his friends Sengoku and Garp, and they had some serious news to tell him.

They met together in a clearing deep inland, where Garp and Sengoku were resting under a tree. Both the Marines wore serious expressions, and even the playful Garp was behaving himself. Upon seeing this sight, Whitebeard knew that the matter was really bad.

Sengoku informed Whitebeard that there was a foe on this island, a very powerful foe which even they would have trouble beating. "And so, I have requested the help of one more man."

Right on cue, the bushes by their side shifted, and a tall and well-built man walked out and approached them. He had jet black hair and mustache and wore a red coat. There was a sword sheathed on his waist, and the man had his signature huge grin on. This man was Gol D. Roger, the man who would soon become the Pirate King.

Whitebeard was skeptical that the opponent was so powerful that they needed four of the world's strongest men to take him down. However, he was soon going to realise that the four of them was barely enough.

"Our enemy is here," Garp said suddenly. Not that he needed to, the four of them had all sensed the man coming ever since he had an intent to approach them. The man at first glance looked like just any other pirate, with blond hair and thinly-slit eyes. He was not wearing a shirt, and his well-shaped abs were proof of his strength. He wore long red pants, and his leg muscles bulged through the fabric of his pants. He wore a grin that had no warmth at all, and the four men's Kenbunshoku Haki sensed his malicious intent.

"My my, to what do I owe this pleasure? Four of the world's strongest men before me," the man smiled.

"Cut your crap, Uvo. We have come to ensure that you don't go crazy with that power of yours by taking you down," Garp replied cooly.

"Ah, my power. You wanna see it?" The man called Uvo began to change. His muscles grew bigger and his devil wings started sprouting from his back. His eyes turned into a glowing red and his smile seemed even more menacing from his devil form. His looks were similar to the boy, however, unlike the boy, he was able to control this power perfectly, and managed to tame the power so that it would do his bidding.

The four men that were about to face him tensed up, as they sensed his immense strength. They immediately knew that this battle was not going to be a pleasant one, nor was it going to be easy.

"Finally showed your true colours eh, Uvo. If only you learnt to control yourself, this would not have to happen," Sengoku sighed.

"GRAHAHAHAHAHA! Isn't it a bit unfair though? It's four on one, how about I do this?" With a loud roar, Uvo cloned three more of himself. The four men knew that one of him was bad enough, but now there was four of him with equal power, this battle was sure not going to have a happy ending.

"The battle lasted for almost a day, and the four of Uvo's clones were on par with our skills. There was not one of us that were gaining more ground, and this battle looked likely to last until one of us falls from exhaustion. That was not the case, though. With Roger's quick thinking, we managed to take down one of the clones. Like that, they were outnumbered and we ended the battle quickly after that," Whitebeard ended his story.

The four commanders were shocked that a single man had been able to keep four of the world's strongest men at bay. "So… you are saying that this boy in our infirmary now has the power to crush the world?" Thatch asked slowly.

"Yes, my son, which is why we need to decide carefully now," Whitebeard nodded.

"That sure isn't good… what should we do with the boy now?" Jozu asked.

"We can keep him, and raise him up correctly to ensure that he has morals and stuff," Ace suggested.

The four commanders agreed that this would be a viable and might be the best option. "What do you say, Pops?" Marco asked.

"He can stay if he wants to. However, Marco, you must stay with him and keep a close eye on him," Whitebeard said.

"Alright," Marco nodded, "Before we end this meeting, there is one more thing we need to settle-yoi."

"The boy's powers. We have no idea when or how it triggers, and how do we stop it. What if the power never awakens again?" Thatch asked.

"So you are saying that we should not tell the boy his powers?" Jozu questioned.

Thatch nodded. A silence descended upon the table as Whitebeard and the four commanders contemplated if they should tell the boy about his powers.

A minute passed. Then two. Then three.

Finally, Marco broke the silence by saying, "I think we should keep it from him, at least until he discovers it himself and asks us about it."

The four commanders decided that that was a good idea, better to keep such a strong power dormant than to try and control it.

And so, the problem was settled and the meeting ended.

The next day

The boy woke up to a burning headache. He vaguely remembered how he fell in the ocean… Wait. Why was he not dead? It was then the boy started taking in his surroundings. He discovered that he was in a very unfamiliar setting.

Around him lay a dozen beds that were currently unoccupied. There were sophisticated machines all around the room, and the boy knew that they were for medical purposes. The layout of the room was one similar to a hospital… except that the boy knew that he was on a ship as he could feel the bobbing of the waves and that he had no idea how he got here. As he surveyed his surroundings, he saw something which made his eyes go wide. Hung on the wall on the opposite end of the room, was the flag of the Whitebeard Pirates. He realised that he was in a dangerous spot and might end up getting killed.

"Oh, you're awake. How are you feeling?" A pink haired woman entered the room and exclaimed as soon as she saw him. She was Nurse Lea, the nurse for the ship of the Whitebeard Pirates. The boy did not trust her and remained silent, all the while staring at her. She was dressed in doctor's garments and she seemed like a kind person. However, the boy reminded himself that she was a pirate too and her looks can be deceiving.

"It's alright if you don't want to talk, dinner's in about half an hour," she smiled before turning and walking away.

The boy knew he had to escape immediately. He was on the ship of the Whitebeard Pirates and knew that he could be killed anytime. He spotted a scalpel on the table by his bedside, and he came up with a plan. He grabbed the scalpel and rushed the woman, trying to use her as hostage to escape the ship.

However, the woman felt him coming and simply ducked under to dodge the boy's scalpel. She then reached out and grabbed the boy's hand. The boy was shocked at her strength as he could not even move his arm despite being fifteen.

"My, my, quite the dangerous one, aren't you. I am a Whitebeard Pirate after all, of course I have to know how to defend myself. Now, go to sleep," as Lea finished that sentence, she delivered a hard chop towards the back of the boy's neck, and he went limp immediately. She then proceeded to put him back in his back before going to tell the commanders of the incident.

"The boy has woken up-yoi?" Marco asked.

Lea nodded. She stood before Whitebeard and the elite commanders and delivered her report. She found out that the boy was fine, just suffering from some minor burns, and his toughness surprised her. She also recounted the incident of the boy trying to escape.

Whitebeard and the commanders listened in silence, but they were all thinking about whether keeping the boy was safe. He has shown aggressiveness, and combined with that power of his, it might bring lots of danger towards the ship.

"Hmm… under such circumstances, it would definitely be better to put him on one of our islands…" Jozu pondered.

"No, we keep him. I'll take care of him-yoi," Marco suddenly said.

All of the people present looked at Marco in surprise. They knew how busy he was as the First Division's Commander and now he was volunteering to babysit a teenager.

"If Marco wants to take care of him, then we shall keep him," Whitebeard said with a tone of finality.

And just like that, the boy with the powers of the devil has been accepted on the ship of one of the Four Emperors, Edward Newgate.

The boy woke up to a state of confusion. He vaguely remembered how he was on Whitebeard's ship, and how the nurse of the ship had knocked him out and foiled his escape plan.

He then noticed a man by his bedside. He was lean and muscular and wore an open purple jacket adorned with a light blue sash. He had an oval shaped face, and combined with his blonde and bushy hair, it made him resemble a pineapple. He was the First Division Commander, Marco the Phoenix.

"Finally awake boy-yoi?" Marco asked.

The boy narrowed his eyes at Marco as he did not trust him. He maintained a calm demeanor and was indifferent to Marco's question. He continued staring at Marco, an awkward silence surfacing between them.

"Not a talkative one-yoi?" Marco asked, "No bother, Thatch is going to whip up a delicious meal for dinner which will hopefully make you feel better. I'll call you when it's time for dinner-yoi," Marco said as he proceeded to the door of the infirmary.

As Marco placed his hand on the doorknob, he heard the boy call out, "You aren't going to kill me?"

Marco chuckled at the question. He turned around to face the boy, only to find him staring with a blank expression.

"Nope, we have decided to adopt you on this ship-yoi," Marco said.

"And why should I trust your word?" the boy questioned.

"You don't really have a choice now, kid-yoi" Marco replied.

"You sure about that?" the boy asked in a sly manner.

Marco raised his eyebrows, interested to see what the boy would try next. The boy rushed Marco, and aimed a right hook towards his jaw. Marco saw it coming long ago and raised up his right arm to clutch his fist, almost effortlessly.

The boy was not to give up easily. Even though he had his fist tightly clutched in Marco's grip, he jumped up and tried to flip behind Marco to attack his back. What he did not expect was that as soon as he jumped, Marco pulled him back down with the arm he was clutching and planted him firmly to the ground.

"Now, now, attacking someone's back is cowardly-yoi," Marco smirked.

The boy finally realised he was completely outclassed, and stopped fighting. Marco looked down at the boy's azure blue eyes. They stared at each other for a while, and Marco finally commented, "Your fighting skills are not half bad, kid, but you still have much to learn. What is your name?"

The air surrounding the seemed to drop by a few degrees as the boy replied, "Jin. My name is Jin."

A/N: And that's it for this chapter! Next up is going to be about his interactions with the Whitebeard crew and his life on the Moby Dick. Jin's power is already revealed, however he is nowhere near the power of the previous user, Uvo. He is at age fifteen now, currently a teen. Hope you guys enjoyed this chapter, and remember to review! Signing off, Shironira-kun.
