I finally finished one of my fics! Another Whitebeard pirates and child Luffy story. But I guarantee you that you've never read a Luffy on Whitebeard Pirates story like this one. Please R & R! Enjoy~

"Luffy! Where the hell did you go?!" Luffy's grandpa shouted. He didn't seem very enthusiastic about their game of hide and seek. But Luffy was good at hiding. He had been with his grandpa on a boring navy ship for a long time. Nothing had been interesting and no one would talk or interact with him for fear of his grandpa. And it wasn't nice sleeping there.

So the minute the boat had docked, Luffy burst onto the mini deck of the marine ship that was waiting out further in the water, and ran down the slope at the walkway and onto the docks, racing between feet and legs. He was small enough not to irritate anyone he hit on his fleeing. There were many people and ships, but no one yelled at him. No one really yells at a three year old kid. Unless they were his grandpa of course.

Garp had followed him off the ship, far behind Luffy, though he would be easy to catch up to since his legs were so small, even if he was fast. So his game of tag turned into a game of hide and seek as he hid behind crates and boxes that pirates were carrying onto their ships.

Garp came into view, so Luffy, determined not to lose their game, climbed into a half empty barrel, ducking his head down and giggling madly as he heard his grandpa race passed him, still shouting Luffy's name. Luffy flattened himself even more so that the shadows hid him in his barrel, which appeared to be housing a ton of apples.

Then everything went dark, and Luffy knew that he had won the game. Grandpa would never find him! Especially now that someone was carrying the barrel Luffy was still in. He quieted his giggles, not wanting to give away his position. But he became surprised, not afraid, when he heard many people talking and laughing as his barrel was lugged around the ship he was now accidentally aboard.

But soon the plethora of voices faded and Luffy was set in a quiet room. There was a round window, which brought light into the storage room. Luffy popped the lid off of the barrel of apples and looked around. It was a new place! He climbed out of the wooden barrel and fell on his butt on the hardwood floor. He giggled.

Luffy went around the room, inspecting his surroundings. He was not afraid, just interested and curious. So he started opening the lids of the barrels and boxes, amazed to find so much food! He wasted no time in gorging on all the different types of foods. Fruits, candy, bread, dried meat, along with many more. He ate until he was so full anymore might make him throw it all back up. The storage room was in disarray. A complete mess of half eaten foods, some raw meat that was not meant to be opened yet.

Luffy pat his full belly and looked around the room for any exits. Grandpa might find him in here. It was time to move on. To explore!

He came across a door that was opposite the one he knew he'd come in from. But the handle was too high. He thought for awhile, his face becoming red, before he had the idea to move a crate over and step on that to open the mystery door. He made sure the stuff his shorts pockets with two apples to eat later.

Luffy walked through the now open doorway and down a dark hall. Luffy may be three, but he wasn't afraid of the dark. Wasn't afraid of much, actually. He wandered down the empty hallway, peeking into doors by jumping for the handles. He found a wide variety of rooms. Bedrooms, bathrooms, a library, a big wide room with strange contraptions in it. It was a big place, and he had lots of space to explore.

Luffy could gently feel the waves rock the ship he was on. He wasn't bothered by this. He liked being on the ocean! But it was very quiet in the hallway. So the boy decided to make his own noises, and began to sing about pineapples.

His voice echoed through the long and deserted hallway, but Luffy liked the sound of it. He continued to open doors and sing to himself until he reached a staircase. Luffy was very small, even for his age, so he knew that he would be unable to climb the stairs easily. Grandpa was usually there to help him. Where was he? Did he give up on the game?

"Oh well," Luffy thought. He did find a ladder down into another room by the stairs, and since that was the only way to explore more, he climbed down the wooden ladder, falling off on the last two rungs. But it didn't hurt and he just stood up and looked around.

There were a bunch of pretty bottles. All very shiny, in their own wooden slots. Luffy had seen grandpa drink some of these, but he was never allowed to taste. Now would be the best chance! Luffy yanked out the closest bottle, trying to undo the lid. He was unable to open it with his little hands or teeth without hurting. So he slammed it onto the ground, thinking the top would come off.

"It broke!" Luffy gasped in horror. Grandpa would be so mad! So Luffy fled the scene, unable to even taste the liquid now sliding across the deck of the winery and alcohol storage. He was able to climb up back to the floor above, fleeing as far from the scene as he could. Now he had no choice but to climb the stairs.

He could do it! He'd prove grandpa wrong. He was a strong boy already. He didn't need hard training to be tough. He was already strong! So he very slowly climbed the stairs, taking each step slowly, as if he were climbing a mountain. He sounded incredibly loud going up the wooden stairs, but he wasn't bothered by it. There was no one around anyways.

He made his way down another very long hall, opening the doors and looking inside each one. Most of these were bedrooms, with bunk beds or even swinging nets that he wished he could get to. But they were much too tall for little Luffy to reach. Well, onto the next room.

But he became hungry again, even after eating his two on the go snacks. His stomach growled as he opened a door to a room with a single big bed and a large desk. And on the table next to it was a pretty, blue-purple fruit with swirls. It looked yummy! So he hopped up and brought down the fruit before taking a big bite of it. He immediately threw the nasty fruit away and tried wiping the bad taste off of his tongue with his shirt. That was nasty! Now he needed to find something to get rid of that taste.

So he wandered on, in search of food once again. Hopefully something yummy.

The cook of the Whitebeard Pirates was going to start unloading the food in the storage and into the kitchen to start to prepare dinner. And what he saw in the storage room shocked him. The room was a complete and total mess. Food was everywhere. It looked like some sort of wild animal had gotten in and had a party with a tornado. What the hell happened in here?!

He quickly put the foods back where they should be, which were much less than they had been when the ship was still docked. He'd need to go somewhere to buy more food! Damn that stupid animal! He was going to find it and cook it himself.

Thatch followed the open door and into the lower hallway. Now he was very confused. Almost all of the doors were wide open, and there was a apple core just sitting in the middle of the hallway. Thatch began to have irrational thoughts of ghosts and demons getting onto the ship.

But he had to know what the hell was doing this, and turned his stupid fears away to follow the disarray left behind. He saw the light on from the wine cellar and peeked his head inside to see a single smashed glass of liquor. But there was no creature or ghost inside the room. So he climbed the stairs.

Whatever had gotten loose on the ship had made its way down this hall as well, where many doors were open wide. Even his bedroom door. Thatch ran to it and looked inside to see no mess. But when he turned the light on, he saw the fruit he'd found that morning laying on the floor. There was a big bite out of it. He sighed, wondering what animal had eaten the Devil Fruit. He didn't want it in the first place, but he couldn't imagine an animal eating something like that.

Then the cook heard a crashing sound from down the hallway and hurried into the most recent open door. He turned the light on to see a very small child trying to climb up the side of the bunk bed.

Before Thatch had any thought about the sudden toddler, the boy fell backwards off the bed frame. Thatch moved instantly and caught him.

"I win!" the kid shouted, and erupted into giggles. Luffy was finally caught, but not by grandpa.

Thatch stared at him for a moment, before holding him more securely and walking quickly down the hall and to where Whitebeard probably was on deck in his massive chair. The boy wriggled in Thatch's grip and tried to climb over his shoulder.

"Don't do that, you might fall," Thatch warned gently. He honestly hadnt been around a child in a very long time, and he was happy to see one again. Despite him ransacking all the food and eating the Devil Fruit.

"Nice guy!" Luffy cheered, looking over Thatch's shoulder. "How many rooms?" he wondered as they passed more doors before climbing down the stairs Luffy had come from.

"Hundreds of rooms," Thatch said, smiling when the little boy "wow!"ed. "What is your name?" he asked.

"Luffy!"

"And what are you doing here, Luffy?" Thatch asked, wondering once again how this little boy snuck onto the ship.

"I play hide an seek wif grandpa an I hide in apples! Den I here in dis big house!" Luffy explained enthusiastically. So, he was in the barrel of apples. Man, how did no one notice him? "I win! He not find me, so I win," Luffy finished just as Thatch opened the door into the sunlight. He made a beeline straight to his father and captain, not saying anything for a moment but holding Luffy out in arms reach right in front of the big man.

"We have a problem." Luffy giggled.

"Explain, son," Whitebeard said after he got over the brief shock of seeing a toddler right in front of him on the Moby. How did he even get on? A crowd had gathered around the two when Luffy became noticed.

"Apparently, Luffy was playing hide and seek and hid in the barrel of apples. He was put in the storage room, which it a complete mess now. He's ransacked all the food, along with the Devil Fruit that was in my bedroom." Thatch sighed. "Though I don't think he meant to do any bad." He held Luffy facing him and asked the boy how old he was. He responded by holding three fingers up.

"I don't think he meant any harm or inconvenience. He was just hungry. He did a lot of exploring today." Luffy nodded in agreement.

Whitebeard looked both concerned and amused. "What were you doing in the barrel of apples, Luffy?" he asked in a friendly voice.

"Hide an seek wif granpa," Luffy chirped.

"What is your grandpa's name?"

"Hmmm… Garp?" Luffy asked, unsure. His name was grandpa, except to other people. Everyone went quiet. Luffy was asked his last name, and he happily exclaimed, "Monkey!" He had a fun last name.

"We have an vice admiral's child on our ship?!" someone from the crowd shouted. Others followed. Luffy just stayed in Thatch's arms and looked around at the pretty scenery of the sea. "Let's take him back!" a pirate shouted, many voices in agreement following.

"Well, we can't go back. The island is swarming with marines that know we're here now. We'll have to wait for awhile and then somehow contact someone higher up. Or we could just drop him off at the next inhabited island, but I'd rather bring him back to his family, yoi," Marco said. The commanders agreed, knowing they could defend themselves, so it wasn't a huge problem to take Luffy back.

No one noticed the big man standing behind the crowd looking at the kid like he wanted to murder him. Which he did. That little shit took away what he'd been looking for for decades. He would pay.

Luffy ate dinner with the rest of the crew at the commander's table, sitting in Thatch's lap, which he offered. Luffy didn't have a problem with it, and Thatch found himself favoring the kid, though he had made dinner difficult. But there was still much food left over, though Ace wouldn't be having four servings for a little while. He'd have to deal with two.

Everyone but Thatch were surprised with how much food Luffy could pack away. Thatch wasn't surprised because he'd seen first hand how much Luffy had eaten from the storage room. Luffy pat his full tummy with a smile. The food here was yummier than at the ship he was on with grandpa.

He voiced that, making Thatch smile and thank him. Ace did not like Luffy. He had never been good with kids, and Luffy was very energetic and loud. Well, he didn't dislike him, he just didn't like him. If that made sense. So he wouldn't exactly be an active role during however long Luffy was staying.

Still, not many noticed Teach glaring at his food angrily. No one asked him what was wrong because that look told them he was feeling very volatile at the moment for some reason.

Luffy was able to stay up until it got dark outside and many of the pirates went to bed. He sat in the kitchen and drew with a pencil on a piece of paper while Thatch cleaned up since Luffy would be staying with him for the night. Luffy began to hum his own song at the table while kicking his short legs off the edge of his chair.

Thatch smiled at him, wondering what his life had been like with the marines. Surely not as fun as their dinner had been. Loud and full of laughter. Even if Luffy didn't know what was funny, when those around him laughed, he began to laugh as well.

"Sach! When we goin' to sleep?" Luffy called from the table.

"In a few minutes, Luffy," Thatch replied, washing the last of the dishes and wiping the counter. Any sort of mess he woke up to to cook wasn't the best start of the day, so he cleaned meticulously after dinner. "Alright, time for bed," Thatch said and picked Luffy up, who grinned sleepily.

A mattress had been put on the floor in Thatch's room for Luffy, with sheets, a blanket and a bare pillow. It was pretty comfortable, and Luffy soon fell asleep, as did Thatch not long after, wondering when they would be able to reunite Luffy and his vice admiral grandpa.

Thatch woke to a strange feeling in his head, like something was missing. He woke up, opening his eyes slowly to see Luffy was gone from his bed, the door open. Thatch immediately got up and hurried down the hall to the bathrooms, and when there was no Luffy, he hurried to the kitchen, with no Luffy either.

He reached out his haki to try and sense the little one, but found nothing matching Luffy. Only lots of men sleeping. But he did feel something like an animal of some sorts out on deck. That wouldn't be Luffy, yet he ran out onto deck anyways. He hurried to the corner of the part of the cabin raised above the deck only to quickly pull his head back and stand still and quiet against the wall.

What the hell is that? he thought as he processed whatever the thing on deck was. It looked maybe only a little over two feet long, was pale purple, and was covered in plate-like scales and blunt horns. What was weirdest about it was the number of legs it had. 6 legs… on each side.

It looked freaky, even to Thatch. Some kind of monster got onto their ship. Then his eyes widened. What if this thing ate Luffy, and that's why he couldn't feel or find the little boy anywhere?! Horror dawned on Thatch's face. He wanted to hurry out and kill that thing for eating the little boy Thatch had become fond of. But he didn't know what the monster was capable of or even what it was.

He slid down the wall silently, still peeping at the thing every few seconds, making sure it didn't move. But he didn't know what to do. For some reason, he thought killing it like that, while it was sleeping, was a bad thing to do. He had no idea why he thought that.

Around an hour after Thatch had sat there keeping watch on the strange creature, he heard noise. He peeked one eye around the corner to see the monster clumsily climbing up the side of the cabin to the roof of it, where Thatch couldn't see it. He took a deep breath, unable to hear it moving around. He didn't like not being able to see it.

Thatch soon felt something wet hit his forehead, and looked up to see the monster's head peeking over the edge of the roof down at him. Drool dripped on Thatch, which was disgusting. He didn't move but his eyes widened when the creature jumped off the top of the cabin and landed next to the man with a heavy thud. He froze in fear.

Thatch kept extremely still while the monster sniffed him, starting at his head to his waist. It was behaving much different than Thatch assumed it would. He furrowed his brows when the thing began to lick him, over and over, with a long, rough tongue. And when Thatch saw the inside of the monster's mouth, he saw the teeth were short and thin, and the tips rounded. It's eyes were also very big. His little horns were also short and rounded as well.

Whatever creature this was, it was clearly a baby. And Thatch did not fear it anymore. It was heavy as it crawled into Thatch's lap, though it didn't fit well. It was just the thing's head and longer neck while it's twelve short legs folded under itself like a cat.

While it was asleep, Thatch felt it's plated scales, which were not as hard as they had looked. They bent a little bit when he pushed them down, like plastic. More proof that this was a baby. But he didn't know what it would do if Thatch got up and left. There was still the missing Luffy. Yet, he had a feeling Luffy was just fine, and that he somehow recognized the creature sleeping in his lap.

He stayed awake the rest of the night, not moving much under the thing's body. He hoped no one came out, because he was against the wall close to the first door. If anyone came out, he'd be seen, as well as the sleeping creature who he had a feeling wouldn't hurt anyone. But, he didn't know that for sure. Even so, Thatch had always had a good intuition.

The man was looking out at the sea as the stars began to dim and the sky got lighter. Thatch felt the creature stir and open its big brown eyes. Then it suddenly got up and walked away, slowly, since it was sleepy. Thatch followed behind it while it turned the corner and tried to stuff itself in between barrels. Of course, it was much too big to fit.p

As the creature began to change shape, Thatch's mouth dropped open as the missing three year old fell forward onto the deck, naked and asleep, but looking perfectly fine. He had a feeling Luffy had been living with the marines for a reason other than being related to a vice admiral.

Disclaimer: I have never had a child or little sibling, so the vocabulary for Luffy might be too advanced for his age, I'm not sure.

Also, since I have never had a kid or anything, some behaviors, mental or physical, might be off.

Review!

Update: reviews are always welcomed, but if you are going to leave one, please do not be cruel or hurtful in them. Please don't message me about how it sucks. It's very hurtful and makes me just want to disable them. Anyways please continue the story if you are interested. If not, please just stop reading. Thanks.

Update 1 year later: So, again, it seems I have to say that Luffy has mistakes. I didn't know that much about young children when I wrote this. Please, ignore the fact he can't walk up stairs. It's not a big problem in the story. And fanfictions have false information all the time. This is minor, please ignore it. It's unnecessary to just comment on that, especially when I've put multiple warnings about it. But here's another one. Thanks.
