Unknown Island, Grand Line

The glowing sun rose from the horizon, bringing with him his light and once again washing the island on his warmth. The wind and his soft breeze blew through the trees and hill to the camp of the island temporary inhabitant Monkey D. Lucas.

Lucas returned exhausted to his hill camp after having his first battle experience against the island king.

Writing down his day on his journal using the last of his strength he then closed his eyes and fell asleep, finally giving in to his body which on that point was screaming for a few hours of rest.

His life with his mother in Dragon Island was really calm and laid back, a life that many would seek after, where he almost never needed to go to the bed tired, so you can only imagine how his hours of sleep became after he really started to tire himself with this training.

After being there alone for almost two weeks Lucas was already getting used to going tired to the bed, but the fight that he had yesterday, being his first real fight, tired him both physically and mentally in a way that he definitely never felt before during his life.

He was barely able to finish his entry on his journal before collapsing, falling in a sleep so deep that he would probably not awake even if someone slapped his face!

So it was not a surprise when he didn't even flinch when an unexpected visitor appeared on his camp and stood just beside him.

The visitor came from the forest just after Lucas had collapsed in his bed, and in quiet steps the visitor approached the young man sleeping and laid by his side, looking at the sleeping young man for a few moments before also falling asleep.

"Ugh… my back"

Said Lucas waking from his deep sleep.

The pain from his back made him recall what he had experienced the day prior, the clash against the tiger was his first experience in a real fight and the lingering pain in his back was proof that it was not a dream. He didn't really remember much of what happened after the incident, only barely recalling arriving in his camp before everything going black.

"When in my right mind before would I have thought of one day fighting a giant tiger? Hahaha... Life can really be surprising, I wonder what that kitty is doin-"

Still a little sleepy Lucas tried to get up and stretch his muscles. The sun was already out, meaning he should already start his day, but when he turned his body to the side what greeted him was two big yellow eyes staring right at him.

For a few seconds he didn't react, small sparks started to fly from his head and you could almost hear the sound of his brain rebooting. Then with a calm and tranquil expression he said:

"What are you doing here?"

Seeing from outside the scene that was transpiring was that of a white haired young man laid in the ground, with a giant tiger beside him, snuggling at him just like would a normal house cat.

Raising to his feet Lucas still a little stunned looked at the kitty before him, he didn't remember much from when he got back in the camp, but he surely doesn't remember having a tiger sleeping by his side.

"You… you are the one from yesterday, right?"

"Growl"

The tiger softly roared as if saying 'yes' to Lucas, the giant cat then hanged his head to the side in Lucas's direction, seeing the action of the tiger Lucas raised his hand and started to pat the tiger's head, who started purring just like a house cat.

The scene of a giant tiger acting just like a kitty threw Lucas a little out of loop. He quickly recovered himself and started to smile, he never intended of this to happen when he saved the tiger yesterday, but this sure is a welcomed development!

"Haha Seems like we are friends now huh?"

"Growl"

"So If we are gonna be friends then I have to give you a name, I can't just call you 'tiger' all the time can I?" He had always been more of a dog person, so coming up with cat names fit for a tiger is something harder to him "What about… Mr. Tawny?"

"Roar!"

"No? then what about Saber?"

"Roar!"

"Tigrão?"

"Roar"

"Come on, that was a good one"

Thinking a little more deeply about the matter Lucas decided to use great figures of the past and see if one of them had a name that would work "Tigers are important figures back in Asia… Kahn is a chief title that can mean 'Sovereign" or 'Emperor', a good fit for the king of the jungle don't you think?"

"Roar!"

The tiger roared again, but this time in agreement. Khan sounded like a fitting name for him, much better than the previous ones. Lucas lightly smiled and then shook his head after seeing the tiger happy expression.

'This development is really unexpected, you go to sleep and awake with a giant friendly tiger beside you. I think a normal person would have not accepted the situation just like that… but then again, I'm not really normal'

Lucas started to walk away while stretching his body, as surprising the moment earlier was he still need to proceed with his day. He started walking in the forest's direction to get his usual breakfast, but then he stopped and looked back at his tiger friend.

"Why are you standing there Khan? Come on, let's get something to eat, maybe later you can follow me in my training. What do you think?"

"Growl!"

The tiger now named Khan growled in happiness at what Lucas said, then without wasting another second sprinted to the young man's side, following behind Lucas as the two entered the forest in search of some food.

July 1517 – Unknown Desert Island, Grand Line

In the depths of the forest you could see a very interesting scene that recently has become quite common in this forest.

The ferocious king of the forest, the Tiger Khan, was calmly walking down a trail in the forest while carrying a white-haired young man on his back, behind the young man the body of a deer hunted by the tiger.

Lucas had a calm and tranquil expression while sitting on the tiger's back. The sunlight that rained from the treetops and the soft wind that came from the sea brought a very refreshing feeling to the forest, a calm that was basically resonating with the two.

With his trusted journal in hand he wrote down a new entry, something that already became a habit for his.

|It's already been a month since my grandpa Garp had dropped me alone in this island, and seventeen days since the beginning of my friendship with the tiger Khan and things had become a lot more interesting, having someone as company after spending two weeks alone in a desert island is a really good change, even if said someone is a tiger.

My action of defeating and then saving him must have painted a really good image of me inside his head, because since the moment he appeared in my camp Khan had been acting just like a house cat with me, and only when sparring or hunting would he show the same ferocious side that I saw the first time we met.

Speaking of sparring, that is something I managed to include on my training regime thanks to my feline friend. Now after my physical training I would have a sparring match against Khan, and man if isn't a great feeling!

We dragon and tiger would fight with the same intensity as our first fight since Khan would not have another way, in fact, the intensity actually increased as the days passed and my strength grew.

Interesting enough the strength of my feline friend also increased as the days passed, it seems we both have been pushing ourselves forward with those sparring sessions...|

Looking up Lucas saw a branch with apples just a few meters ahead of him, he was already in the height of the branch when sitting on the back of Khan, so he only needed to extend his arm to get the apples.

Taking one of them for him he threw another one forward, Khan that was walking forward opened his mouth and caught the apple in midair

|My powers as the Lightning Dragon continued to improve with each passing day, molding my lightning in simple forms like a sphere got really easy, so I started to change my focus to other aspects of lightning.

Contrary to what many would think lightning powers are not only to blast thinks with great power, electromagnetism, for instance, is another aspect of lightning powers that can do wonders. Unfortunately this part of my powers is still far from impressive, as for now I can only lift small thinks with this technique, which means I'm far from becoming the second coming of Static Shock or Magneto.

Having Khan with me also helped me train other aspects of my devil fruit powers, following the King of the Forest during his hunts really put my enhanced senses to test, for instance, the sense of smell I had prior the dragon powers could not hold a candle to the ones I had now.

Being able to follow along with a trail left by someone hours earlier just by smell, or being able to smell something specific from more than a kilometer is something that normal people simply can't understand.

Flying is another thing that I'm doing more these days, and honestly I think it will probably become an addiction for me.

it's just too good!

The sense of liberty I got when turning into my Dragon hybrid form and flying is something breathtaking, it's just… Sigh.

Overall my days had been quite pleasant recently, with the exception of some hiccups. My memories of the canon had become even fuzzier than before, for instance I just can't remember the names of all the supernovas without looking in my journal, or where In the fuck did Ace fought Blackbeard.

I have probably forgot other things, but honestly I don't know, thankfully it had still not reached the point where I would not remember about the major points of the canon, but sometimes I think that may happen one day, a point where I would be just like any other person of this world with no future knowledge.

Then again, who knows how much of the canon will be the same when I reach that point?

Let's not talk about when I started to travel around the world, just me being here on this island writing this journal may have already shifted many things in the future ahead. Well, not that it matters to me at the present moment

This is a problem for the future me to handle…|

Arriving back at his camp Lucas picked the deer from Khan's back and started to prepare their lunch.

Back in Dragon Island he had learned with his neighbor, the owner of the meat shop, a few things about how to prepare a fresh meal in the wild. Nothing major, just the basics during the time he did a chore for the guy, just enough for him to prepare a part of deer for himself, the rest of the meat would be eaten by Khan.

"Roar!"

"Huh?"

At one point Khan started to roar towards the sea, a confused Lucas turned his body and what he saw really surprise him. A look of pure happiness in his face as he saw the familiar green marine ship arriving at the sandy shore close to his hill

"GRANDPA IS BACK!"

Running as a bullet fired from high caliber gun he sprinted forward to meet his grandpa Garp, his tiger friend following just behind him.

It didn't took long for the two to arrive at the shore, the grassy terrain giving away to soft white sand as the two sprinted across the beach, without noticing Lucas tapped at his powers making him run faster than normal, his footprints in the sand having a lightning afterglow thanks to that.

The familiar green ship didn't even had time to properly arrive at the shore before a shadow jumped like a bullet from it

"BWAHAHAHAHAHA!"

With his trademark laugh Garp jumped across the water and the sand, landing just a few meters ahead of Lucas.

"Oi Lucas, how is my grandson doing?!"

"HAHAHA I'm doing great, grandpa"

Answered Lucas with a big smile on his face, seeing his grandpa after a month on this island really brought a good feeling to him. His grandpa Garp this time was not wearing his Vice-Admiral clothes, instead, he was wearing sandals, along with a red tropical shirt and light-colored shorts "Are you on vacation Grandpa?"

"Oh this? I just thought that was better to wear something less formal when visiting my grandson" Garp gave his grandson an analyzing look, nodding in approval at what he saw.

In his month in the island Lucas clearly grew some muscles, making Lucas look fit but not buffed like him, the augmentation of the dragon powers only gave him a push, the rest was done thanks to his efforts.

His skin grew a tad darker thanks to the sun, just some tones lighter than his own. Because of the powers of the Dragon his body didn't have many bruises, only a few recent scratches, his clothes on the other hand could do well with some patching work. All in all his grandson looks like he is doing just fine.

'Just as expected of my grandson' Looking behind Lucas he finally saw the giant tiger standing there "You are doing really good I see, even tamed a tiger for a pet, just as expected of one my grandson! BWAHAHAHA"

"Hahaha I almost forgot, this here is Khan, he was my first opponent in this island, we became friend since then" Lucas introduced his feline friend to his grandpa with a smile at his face, Khan that was behind him gave a roarbasically saying 'My name his Khan, nice to meet you Old Man' which made Garp laugh.

"So grandpa, what happens now?"

"Now? Bwahaha" he grinned as he started to crack his knuckles "You have been here one month already, time to see your improvement!" Garp laughed seeing the surprised face of Lucas.

Lucas was stunned at first, caught kinda off-guard by his grandpa direct way, but then he gave a smile just wide as that of his grandpa. Jumping a few meters backward he assumed a fighting stance.

"Hey Khan, give us some space"

A few sparks coiled around him as he said that, his friend tiger gave them space at Lucas's request.

Lucas expression was a mix of excitement with nervousness

'There is no way I'm going to win…' said his rational mind, while his inner dragon said '… but maybe I can still cause some scratches'

Garp grinned and nodded at Lucas's action, he on the other hand did nothing apart from twirling his shoulders a little causing a few cracking sounds.

He just stood there, calmly looking at Lucas with a smile at his face.

For a few seconds Lucas did nothing as he tried to see what his grandpa would do, but then he realized that his grandpa was waiting for him to move first.

Swoosh

With a might push of his legs he dashed at his grandpa's direction, practically becoming just a blue beam light. Lightning cracking on his fist as he punched at his grandpa.

[Lightning Dragon Fist]

BOOMM!

With a loud thunder crack Garp became covered in light.

For a moment Lucas thought that he might have landed a good blow at his grandpa, but that thought vanished quickly when he heard a familiar laugh. The light vanished to show his grandpa standing without any scratch, his right hand raised above his chest holding Lucas fist with no problem whatsoever.

"BWAHAHA Lightning Dragon Fist? That tickles"

Lightly flicking his hand Garp threw Lucas skidding a good twenty meters backward.

Recovering himself Lucas looked back at his grandpa who was smiling widely "Oh, really? Then how about this?!"

The air around him started to crack as lightning started to cover both his arms, jumping in the air he raised his hands, the lightning flowed from his arms to his hands becoming two spears made of pure destructive energy.

[Twin Lightning Spears]!

With a dragon roar he hurled the lightning condensed spears at his grandpa, falling down his feet barely touched the sand before he dashed again at his grandpa. His hands turned into claws and his arms became covered in scales as he followed after his spears, the three leaving a trail of heat in the sand as they dashed forward.

ZAP! ZAP!

The two spears flashed forward with great power, in a literal flash they arrived at Garp, covering his body with their light as they are aimed at his sides, the idea being that he would need to use both his hands to block the attacks, leaving Lucas with an opening.

The white haired young man was dashing just behind his spears, changing his course in the last second he practically blinked at appeared behind his grandpa, then with a loud dragon roar he punched again.

Unfortunately to him he failed to see the smirk forming in his grandpa's face.

BOOM!

Another thunder crack was issued on the beach, the sand around them was blown away by the power of the three-way attack, the attack so powerful that was even heard but the marines left by Garp on the ship.

However, despite its impressive display of power Lucas's attack was still no enough to move Garp

"?!"

Lucas gasped in shock at the scene that just happened before him.

In the last second when his combined attack was about to work his grandpa that was motionless the entire time suddenly moved with inhuman speed and precision, with a slight bend of his body he avoided the spear at his left, his right hand raised he punched the other spear into oblivion and caught Lucas's fist with his left, all along his smile never left his face.

Lucas looked stunned at the glowing crater created by one his spears behind him, then at his grandpa right hand who had not even a single burn mark.

"Localized transformation? BWAHAHA Good, but still not enough!" Gap said laughing as he looked at his grandson's now draconic eyes.

With a low growl escaping his throat Lucas attacked again, moving his other fist he punched again at his grandpa, who used his other hand to catch his fist.

Bending backward Lucas escaped his grandpa's grasp, landing on his hands he twirled his body and kicked his grandpa. Garp easily caught Lucas by his feet's, then with a laugh he launched his grandson high up into the air.

Stunned first at his grandpa's action Lucas quickly recovered, with a thought his legs also became covered in scales and started to glow with lightning. Throwing his body forward he started to spin in the air just like a lightning edged spinning saw.

BOOOOOMMMM!

Another even louder thunder crack rang across the beach, a giant crater was created around the grandpa grandson duo.

"Your growth has been good, now, here is your first lesson"

Lucas that was feeling like he just kicked Mount Olympus didn't even got time to see the effect of his attack before being throw backward with great force, landing face-first at the edge of the crater he recovered himself and looked at his grandpa's direction, only to see a giant fist already on his face.

"ARGH!"

Lucas was thrown backward again, using his hands as support this time he managed not to land on his face.

Looking up he saw his grandpa already almost on top of him, jumping to the side he barely managed to avoid Garp's fist which landed on the ground creating another crater and raising a cloud of sand that covered Lucas.

Still grinning Garp launched another punch to his left, parrying with ease Lucas's fist that came from within the cloud of sand. The clash of the two Monkey D. fists created a shockwave that blew the cloud of sand away, revealing Lucas who took advantage of the coverage of the sand to assume his hybrid form.

"So this is your hybrid form? BWAHAHA" still laughing Garp dodged Lucas's tail attack and punched at the dragon, the punched connected making Lucas stagger.

'Is this what being hit by a meteor feels like?'

Lucas raised both his arms blocking another punch, with a flap of wings he created a cloud of sand around them in the hope it would give him some breathing room.

But his hopes were cut short, as just a second later his grandpa's fist landed in the middle of his chest, this time the blow came heavier than before, his trusted black dragon scales are good as normal skin before the Marine Hero's fist.

Lucas was throw away again, landing on his back this time however he didn't have the strength to stand back again, his transformation receded as he gripped his chest in pain.

"Argh… This hurts!"

"What's wrong with this face, already throwing the towel?" said Garp calmly as he approached his grandson, contrary to Lucas who was in the ground bruised, he didn't have a single scratch apart for a few burn marks in his clothes. His smile left his face as he looked at Lucas with a rare stern expression.

"If that was the limit of your skills, then it is better for you to give up on the idea of becoming Fleet-Admiral. Do you think I'm joking? Your father was stronger than you when he was your age and he didn't even any devil fruit, let alone a rare one like your's. Even so he was still able to push me way more than you do. You told me your dreams, they are very high and demand high strength to match them"

Lucas lowered his head in defeat, he who was never talked with such stern voice by his grandpa became filled with bitter feelings, he never intended in winning against his grandpa, he only wanted to impress his grandpa just a little with his growth, the thought of receiving such scolding never crossed his mind.

Garp saw the look of his Lucas, his expression softened a little at that

"This is my first lesson to you, there will always be someone stronger than you out there, you will taste defeat many times in your life, but don't let them get the better of you, use them as drive to never stop improving. The life of a marine is not easy, so you better prepare yourself very well"

Lucas looked at his grandpa as he took in his words, he better than most knows how true his grandpa words are, how big the power of the many monsters that live in this world is, someone like him really don't have an ounce of a chance if he faced them, but was the mention of the danger of a marine life in particular that resonated deep with him, after all, his father lost his life to this profession.

'Is this his way of showing his concern?'

Different from his mother his grandpa never showed a sign of concern when he expressed his desire to become a marine, but how could he not be concerned? Who better than the Marine Hero to know about the danger of their profession? He already lost a son to this life after all.

But is not Garp's style to stop Lucas from going after his dreams after he expressed them just because they are dangerous, he would just laugh and give his grandson all the support and training he could, which is exactly what he is doing now.

The bitter feelings inside of him had been blown away at this realization, his smile returned to his face as he got back up "Hey grandpa, when did the words 'I give up' left my mouth?"

"BWAHAHAHA so you still have some fire on you huh?" Garp laughed and cracked his knuckles, an approving look on his face as he looked at his grandson, who had his eyes literally glowing with renewed energy "Can you take another beating?"

With lightning coiling around him Lucas assumed his fighting stance with a smile "Always!"

"BWAHAHAHA"

"HAHAHAHA"

The two dashed at each other again

February 1518 – Inside Garp's Marine ship, Grand Line

|…Since grandpa's arrival on the island that day my training increased to an absurd level of intensity, each day I would go to bed barely being able to move a muscle, and there I thinking I knew what being tired was.

Not that I'm complaining, in fact, I embraced every single moment of the hellish training with gusto, after all, pain is just weakness leaving the body right?

The lecture my grandpa gave me that day really opened my eyes, if I want to achieve my dream of becoming Fleet-Admiral, or have my revenge against the 'strongest creature in the world' known was Kaido, I will need power, and to have the power I must improve myself nonstop.

Thankfully my grandpa helped me bring these goals of mine a few steps closer.

Apart from the daily beating he would give me every day he would also help me improve my fighting techniques, which was a good fit considering that just like him I didn't use weapons.

Grandpa is someone that really encourages you to have your own style of fighting, he would only polish the style to help it become more effective, but the work of creating the base for the style in The first place was basically done by me.

The control of my lightning and transformations also climbed many steps forward, moves that would before burn all my energy now are party tricks to me, and transforming specific parts of my body became basically instinctual. At one point I also got to try my full transformation, and oh boy how awesome it was!

The feeling of growing to be big as a ship is one of those things that no word can ever dream really explaining, I ended letting out a big thunderous dragon roar at that moment that was probably heard even in nearby islands…|

Sitting on the bed inside his room in the ship was Lucas calmly writing on his journal, the tattered clothes of his time on the island had been changed, with things back he was now able to return to his normal look.

Finishing with his journal a few minutes later he turned his attention to his room, looking around the room was not much different from the time when left Dragon Island, the only big difference being the laying giant tiger beside his bed.

Khan became very attached to Lucas during his time in the island, so much as when the time to leave came it was practically a foregone fact that the tiger would leave with them.

"I still wonder what you saw in me Kitty"

Khan only response as just a low growl.

Laughing at that Lucas turned his face to the window beside his bed, where he could only stare in awe at the majestic beauty of the island on the horizon, the place where the marine headquarters was.

At that moment inside Lucas's mind, where excitement and expectation rolled in waves, only a single thought could be heard:

'I have arrived Marineford'

...

...

...


...

So yeah, that was the end of our protagonist training on this island, I ended the training now because I wanted to start his life as marine already, he may have some flashback's to show new parts of his training but for now this is all there will be. I hope I did good with my portray of Garp's in this chapter, someone that is always smiling but can become serious in matters related to his family, a speech after giving a beating his something just his style in my opinion, the fight he had with Lucas was very fun to write.

Anyway, I have to give a special thanks to everyone that marked this story favorite/follow, serious, you all are awesome. leave your comments if you feel like it, constructive critics are welcomed.
