Chapter 1: The beginning of the myth
The East Blue was known for being the weakest of all the seas but being the weakest sea doesn't mean that greatness will rise from it, such it's the case that in a certain island will someone exceptional.
Dawn Island
The island was known for being a rather peaceful place specially in the Foosha village but today was a rather special since a pirate crew known as the red hair pirates were celebrating alongside a young boy, this boy's name was Monkey D. Luffy who in his latest attempt to prove that he is brave enough to join the pirate crew he stabbed a knife under his left eye that left him with a scar in the place where he stabbed himself so the crew threw him a party to cheer him up.
"Come on Shanks, let me go with" Luffy said asking the captain to take him on a journey only to receive as an answer that he is still a kid thing that makes Luffy at little angry to the captain.
Said man smile seeing the boy being determined about going on adventures just like a certain man that he used to know but he was adamant in his decision, "Luffy is way too early for you to in adventures with us so try to be patient your time will come" said Shanks trying to calm the young boy's spirit.
Luffy didn't understand those words at moment but decided try to put his mind on other things until he set his eyes into a treasure chest that was besides a sword that was chained from the handle to the sheath, Luffy decided to see the content of the chest and he found a black pomegranate with some red spiral marks that has a note next to it he thought that it was the dessert so he started eating it while no one was paying attention though is worth mentioning that it didn't taste good but that didn't stop Luffy.
At some point a group of mountain bandits came to the bar asking for booze, but when they were refuse of it because the pirate have drink it all the leader was furious and decided draw his sword to cause problems to stopped by Luffy that was growling like a dog put himself in the middle between him and Makino who was like a mother to him, the leader of the bandits became even more furious that he tried to cut Luffy and Makino together only to stopped by Shanks who using his own sword to stab the heart of the leader dropping dead at floor meanwhile the other bandits were shot to death by the members of the crew.
After dealing with the bandits while some members were cleaning the mess Lucky Roux the chef of the red-haired pirates informed his captain that the devil fruit that they stole disappeared, Shanks was having a good idea of who could've take it and he happy about it so he looks to Luffy.
"Well, Luffy I think that I will train to use a sword so that way you protect the people dear to you" Shanks said while patting Luffy's head like a proud father would to his son which make Luffy happy about it.
A month later
Shanks was sure to train Luffy in the basic uses of sword by practicing with a wooden sword that would eventually lead to fight with real swords in the future, he also trained Luffy into creating slashing attacks that he would throw with his sword to cut enemies from a distance when they were far away from him. The other members also help with the training so that Luffy could steer the wheel of a ship, fight from many angles and even know when not to fight because there are fights that are not worth fighting. when the time to leave came Shanks and his crew were ready and what was left to do was to say goodbye.
"So, you not going to ask me to take you with us" Shanks said wondering about Luffy's answer so they can finally said goodbye to each other leaving as a gift for the young boy the same chained sword that was near fruit that day while managing put the note in the chains.
"No, I won't ask you to take me with you" said Luffy in determined tone only to receive from Shanks an answer in a mockery tone while sticking out his tong "I wouldn't take you anyway, there's no way you will become a pirate".
Luffy couldn't take it anymore so he decided to speak his mind so that even the heavens could hear it "yes I will, one day! I will have a ship and crew that is better than yours! and we'll find the biggest hoard of treasure in the world! I will become king of the pirates!" while saying that he felt like crying for the release of emotions.
"So you're going to surpass us, very well then do me a favor a keep this hat safe for me" Shanks said putting his hat over the head of Luffy who was still crying while continuing to say "this hat means a lot to me, promise that you'll give it back to me someday when you've become a great pirate" after Shanks's crew left dawn island to never been seen again leaving Luffy with a powerful dream to achieve and a meaningful promise to fulfill.
Mount Corvo
a whole month have passed since the promise of Shanks and Luffy so right now Monkey D. Garp the hero of the Navy was carrying his grandson towards a small cabin in the mountains. He heard that "Red-Haired" Shanks have been in the island and "corrupted" his precious into piracy. So, he decided to bring Luffy to a group of mountain bandits that owe him big time for not sending them to jail.
"What the heck grandpa? I don't want to go to a stupid cabin in the mountains. I want to be free and be a pirate." Luffy said as he struggled in his grandpa's grip.
"I don't care. You're going to stay up in this mountain until your old enough to be a marine, I won't forgive that bastard Shanks for putting ideas of becoming a pirate, but he did gave you a cool sword even if its surround by chains." Garp said not leaving any room to argue. But Luffy just yelled that he was going to be a pirate like he always does, when his grandfather says he will be a marine. After a little while Garp and Luffy were at the mountain bandit cabin. Luffy wondered why this cabin was here, but before he could ask his grandfather. Garp banged on the cabin's door, and out of it came a large red headed lady. "Whatever you're selling we don't want!"
"Dadan! It's nice to see you again!" Garp yelled at the red headed lady. Hearing Garp's voice caused Dadan to fall back and two of her subordinates to come out of the house. A small man and a tall fat man. They also saw Garp and were completely afraid of what he would want them to do this time.
To say that they were surprised is an understatement. Garp wants them to watch over his grandson! "Hell no! We don't want to!" All three of them yelled with scared faces.
"Well considering what crimes you all committed in the past. You three can either watch over Luffy, or you can all go to jail. So what is your decision?" Garp said giving an ultimatum. Hearing that made all three of them start to swear bullets. They could either watch over Ace as well as Luffy, which is one form of hell. The second version of hell is going to prison and never seeing the light of day again.
And they knew that going to prison was worse than anything else. So, in the end, they decided to stay out of prison and watch over Garp's grandson. "FINE WE'LL TAKE HIM!" All three of them yelled at the same time to a smiling Garp.
"Alright. Now take good care of him. Train him and make sure that he is well fed. I'll be back later to check up on him." Garp said as he left, waving back at the mountain bandits.
However, while Garp and the mountain bandits were talking, Luffy went into the forest and met his new brothers. They didn't get along at first, but after a little while, they managed to become close friends and call each other brothers.
Two weeks later
Right now Luffy, Sabo, and Ace were looking around the forest for something to eat, since the bandits already ate everything in the cabin for the morning. Ace kicked a rock into a tree and grumbled. "This suck. I can't believe those idiots ate all of the food before we could get any."
Sabo looked at his brother and spoke. "Yay. But at least we were able to beat the crap out of some of them before we left as payback." He smiled and cracked his knuckles for fun. But Luffy wasn't bother at all since he managed to eat the portion of a big size for a kid.
As they continued to walk through the forest, something the smells of Luffy that guided him and his brother to a cave in the mountain. Upon entering the cave, the three brothers could what see that it had a workshop inside of it with a large table that had blueprints and tools to work on it and also two fruits near a circular forge. The one on the left was an orange with yellow and black coloring. And the second one on the right was a bunch of grapes with a red, gold, and black coloring, The boys looked at the fruits and ran to them without a second thought. Sabo grabbed the one with yellow and black coloring. Ace grabbed the red, gold, and black colored fruit. At the same time the brothers bit into the fruits and swallowed the juicy pieces.
But after a few seconds the two brothers had sour looks on their faces. The fruits may have looked tasty, but they tasted terrible. They tasted like the most sour and disgusting thing that they have ever tasted in their short lives.
So, they dropped the fruits back onto the ground and started to try and cough up the fruit, but with no luck. After another minute, the two brothers stopped coughing and looked at the notes that was behind of each one of the fruits that they ate. They each looked at each other and picked up their respected notes. But before they could start reading the notes, Dadan called out to them, to come home because they have guests. So the brothers pocketed the notes, and started to head back to the cabin to see who was visiting them
Nighttime
Luffy, Ace, and Sabo were currently eating dinner with the Dadan family. With their guests the mayor of the town and Makino. They were there making sure that Luffy, and his new brothers were eating well, and staying safe. As they continued to eat Luffy, Ace, and Sabo were talking about how they were going to each become pirates. Create their own crews and sail all around the grand line. That is until Garp showed up with a deranged smile on his face. Everyone saw Garp and swallowed hard unsure of what to do.
"So all three of you still want to become pirates huh. Well, I guess that I'll have to nock some sense into all three of you. Starting with you Luffy." Garp grabbed Luffy by the rim of his shirt, picked him up and was about to give Luffy a punch of love. Everyone looked on worried about what to do. Garp launched his fist as Luffy placed his arms over his face to protect himself. And what happened next shocked everyone, especially Garp. As his fist collided with Luffy's arms, they instantly changed. No longer were they regular kid arms, but now they looked like the arms of a wolf. They were covered in jet black fur that could only be found in the deepest part of hell, with his nails becoming sharp grey claws.
Everyone was so shocked no one moved or said anything for a full minute. But once Garp got over his shock, he dropped Luffy and started to stomp his foot on the ground. "Damn it! Damn it! Damn it!" Was all he could keep saying as he realized what Luffy just did.
A few more seconds passed by and Garp took a deep breath. Then he started to yell at the top of his lungs once again. "What the hell did you kids do?! How did you get your hands on Devil fruits?!"
The three brothers didn't understand what Garp was talking about. So Garp pulled out a book with pictures and facts about different devil fruits, and started to explain to the boys what devil fruits are. And what they do to people that eat them. Once he was done, Garp asked them what devil fruits that they ate. None of the boys knew what fruits they at, until Luffy remembered the notes that were in front of the fruits. So, he took his note from the sheath of his sword and gave it to his grandfather. Garp took the note and read it out loud for everyone to hear.
"To whoever eats this fruit, know that you have eaten the Mythical dog dog fruit model Cerberus. This devil fruit allows the user to have the powers of guardian of the gates hell Cerberus itself. Which will allow the user to create and manipulate pure darkness and its derivates. So, you can create weapons of darkness, darkness appendages, clone of darkness, darkness projectiles among other things. The user can even infuse darkness element into weapons to increase their cutting power, increase their length and send long range light attacks through them. The hybrid form of this Devil fruit is a werewolf with three heads and a snake for tail. While the full beast form is Cerberus a three headed monster dog that guards the gates of hell. The size of that forms has a height of 30 feet tall. And it can grow according to the user's will. This fruit also grants the users super strength, super speed, enhanced senses especially smell and hearing, superior healing factor, a strong and deadly bite and a deadly howl as well of enhanced durability, large amounts of stamina and endurance." Garp finished reading the note, and everyone was almost floored by the abilities that Luffy now possesses.
Ace was the next one of the three to give Garp his note. Garp took the note and started to read it out loud just like he did with Luffy's note. "To whoever eats this fruit, know that you have eaten the Mythical cat fruit model Chimera. This devil fruit will grant you the powers of a Chimera. It allows you to form objects made from fire. Flame clones, flame weapons, flame appendages, flame projectiles and flame pillars. Just like the Cerberus fruit, you can infuse your flames into weapons to make them more durable, increase their length and cutting power. Increase their length and send flame-based projectiles through them. The hybrid form of this Devil fruit is a three headed being conformed by three animals: a lion, a goat and a dragon having the legs of the goat, the arms of the lion and the wings of a dragon on its back. The head of the lion takes form depending on the gender of the user meaning that it will be a lion head if it is a man and a lioness if it is a woman. And its full beast mode is a Chimera a monster a creature of nightmares that has size of ten feet tall. And can from to fifty feet tall. This fruit allows you to have the ability to fly, a fire roar, feline reflexes, increased speed, strength, and dexterity." Garp finished Ace's note, and everyone was floored by it.
Sabo was the final one of the three to give his note to Garp. Everyone held their breath and waited for Garp to read what Sabo's new powers will be. "To whoever eats this fruit, know that you have eaten the Mythical bird fruit model caucasus eagle better known as the hell eagle. Like the chimera fruit this fruit allows you to create objects made of fire, but unlike the other this fruit's fire has a blue flame instead of a red one like it will be flame born from the depths of hell. Just like the Cerberus, and chimera fruit, you can infuse your hell fire into your weapons to make them more powerful and send projectiles through them. The hybrid form of this Devil fruit is a large bald eagle man that will have sharp claws as hands and wings on its back. And its full beast mode is a large bald eagle that produces blue flames from his wings. This fruit allows you to have enhanced sense of sight, the ability to fly, greater speed and maneuverability in the final form." Garp finished the final note, and everyone began to process what he just said.
After a few minutes Garp straitened up and took out his snail phone. Dadan saw what was in Garp's hand. "Who are you calling Garp?" She said with a stern look.
Garp saw the look in her eyes and simply said. "I'm going to call the head admiral of the marines, Sengoku. So, he can come here and train these three boys. Since he is the only other person that I know that has a Mythical Zoan type devil fruit. He will be the perfect teacher for them."
Navy headquarters
Right now, head admiral Sengoku was getting ready for bed. He had his nightwear on and was about to lay down on his bed, his transponder snail started to ring. Causing him to fall face first on the floor and groan out in pain. "Whoever is calling me at this time, better have a good reason. Or they are going to regret it." Sengoku groaned out as he got up from his floor and picked up his snail. Sengoku looked at the snail and saw that it was Garp who was calling him. And if it was Garp calling him, then it had to be important. He answered the snail and heard Garp out.
"Listen Sengoku I need you to come to my home island as soon as possible. My grandson and two other boys that he considers to be his brothers, all ate a mythical Zoan type devil fruit. And now they need training on how to properly control them, or they could cause some serious problems. We might as well teach them about Haki, that way they don't think that there invincible. It shouldn't take more than a year to properly train them in the basics. Then give them some written literature about the more advanced parts about Haki. So come here as soon as you can. See you soon." Garp finished and the snail transponder went quiet.
As the transponder snail continued to just beep. Sengoku let out a loud yell "DAMN YOU GARP!" Sending out a loud roar all over the island causing all of the marines to cower for their lives.
Dawn island
Right now Luffy was walking through the forest looking for the cave where he and his brother found the fruits. His grandfather told them that the person who will be training them will be here in a week. Because he needs to find a temporary replacement for him while he trains them. When Luffy found the cave once more he investigates the workshop and after lighting on some lanterns and candles Luffy would see what the hidden workshop has to offer.
In a wooden table Luffy found five blueprints for five different weapons: the first was a sword different from others since the blade had a blue like coloring and the form of a wing, it had 9 feet of length with a half inch width, the guard was shaped into the form of wings, the handle was cover in grey leather wraps around it while having an eagle feathers's on it and the pommel had an eagle's head. On the top the of blueprint was the name of the weapon which is is called "Hellwing of Freedom". The second weapon was a double headed great axe with each of the blades one foot in length and one eighth in width with one the blades having a shining red coloring while the other blade having a pitch-black color. The handle is six feet in length and one inch in diameter. The pummel of the axe is in the shape of a lion. And all over the axe handle and the axe blades themselves were images of a dragon, a lion and a goat carved into the weapon. The name of the weapon was revealed on top of the blueprint being named as "Wild roar of the Chimera".
The three last weapons were three katanas that look almost similar from one to another to some degree: all of them were six-foot length and half inch width. The handle of the blades was rectangular shaped with what appeared to be leather raps around it, the sheaths of the katanas were engraved with same symbol that being the omega Ω made in gold. But each of them has something that makes them different from the other two being the case that the first katana was a dark katana with its guard shaped like a skull, black wraps around the handle with the pommel having the shape of a skull, red skull marks around the ebony sheath and the blade had a red flame pattern. the second katana was a blue katana with its guard shaped like a water current, blue wraps around the handle, with pommel having the form of a drop of water, the sheath have the color of the ocean with marks taking the form of waves and the blade had a blue wavy pattern. And finally the third katana was a white katana with a lightning for guard, golden wraps in the handle with an eagle feather, the pommel was shaped like a lightning, the sheath was white with golden touches on both ends while having a gold lightning pattern on it and finally the bale had a yellow lightning pattern. the names of those katanas were respectively "Shadow Katana of the Dark lord", "Ocean katana of the Sea king" and "Bright Katana of the Sky Master".
Luffy recognized the first katana as the one that Shanks gave not so long ago and feel even more enthusiastic of having it. Luffy looked at all of the blueprints and he could feel that each one of the other weapons were for his brothers. The Wing blade for Sabo and the axe for Ace, he couldn't figure to who would the katanas belong to but he would figure it out at some point. So, he decided to learn how to make these weapons. All the materials that he would need are right here in this cave. But now what he needed to do was learn how to make them. Then he and his brothers will have what they need to protect themselves and those around him. So, he grabbed the blueprints and headed back to the cabin and see what his brothers would think about making them with him.
