Hey guys! I love time travel fanfics and there aren't many where Luffy and Ace go back in time and meet Roger and Whitebeard so I decided to write one! Updates will be random since I'm also writing a Luffy and Dragon fic at the same time.

Chapter one: The disappearance of the straw hat

Luffy was starting to get excited. They were on their way to Whole Cake Island to retrieve Sanji, and he knew that the whole ordeal was going to be another adventure. He was currently sitting on the figurehead of the Sunny, waiting in anticipation for any signs of the island. It was starting to get very late though, and he was starting to get tired.

"Hey Luffy, what are you doing?"

Luffy looked behind him to see Chopper looking up at him with curious eyes. He grinned, eyes glistening in the moonlight.

"I just can't wait to get to the island. So much is happening and I really wanna see Sanji again".

"I know, I'm really worried about him too, but it's getting really late. It's going to be past midnight soon. I think you should go to sleep, after all, we're going to need all our energy when we get there."

Luffy started to make his way off the figure head, knowing that the small reindeer was right. So much has been happening recently with Dressrosa and Zou that he didn't have much time to sleep. "Yeah okay, I guess we're getting close now aren't we? Well, I'll see you later Chopper, goodnight!"

The cheerful captain made his way to his room, and the moment his body hit the bed, he instantly fell asleep.

The sound of the waves crashing was peaceful. The rocking of the ship made Luffy feel comfortable, as he dreamt of the sea. He was consciously awake now, but he didn't want to open his eyes since he was so comfortable.

He rolled over to his left side only to run into…a wall? It was only then that Luffy realized that he was sleeping on wood, and not on the soft mattress of his bed. He sat up slowly, yawning as he looked around. His tired eyes surveyed his surroundings as he was still trying to differentiate from the dream he was just having and the reality he was in.

As he looked around, he realized he was looking directly at the ocean.

Hmmmm that's weird, did he sleep outside on the deck or something? He was pretty sure he was in his room sleeping near the other guys on the ship, but he couldn't see anyone else there. Actually, he couldn't see anything but the ocean. He was also very close to the surface, which surprised him since the Sunny is a big ship and he should be much higher up than he is now.

Luffy looked down, only to realize that he was on a small boat. Alone. Not on the Sunny were he should be.

There was nothing else on the boat. Luffy blinked in confusion.

Well, that's strange. It's a mystery!

But wait! He was alone on a boat, and he couldn't see any ships anywhere near him, only the ocean.

"Areeee? Where am I? How am I supposed to get back to the Sunny?" Usually mysteriously waking up in the middle of nowhere would excite him since it would mean that a new adventure was beginning, but Luffy couldn't see anything around for miles except the ocean. He didn't want to stay stuck in a boat, that would be boring! Not to mention, he wanted to get Sanji as quickly as possible since he was worried about Zoro's group that went to Wano. But he had no idea what to do or how to get back to his ship.

"Hmmmmmm….. I can't swim, and I'm alone….", Luffy contemplated as his face started to turn red from all the thinking.

"Mooouh, I give up, this is going to give me a fever, I'm just going to wait here for a while I guess. I'm sure Nami and the others are looking for me." He laid back on the small boat and closed his eyes, taking in the feeling of being out in the ocean. The wind blew across his face and hair carrying the scent of the ocean, and Luffy sighed contently as his hand reached up to rest on his straw hat out of habit.

Wait a minute….. hat?

Luffy's big round eyes flew open as he shot up in a state of panic. His hands searched his head and his raven locks.

There was nothing there.

He searched the small amount of space around him on the small boat frantically.

Nothing….

Nothing nothing nothing nothing nothing….

It was gone, GONE!

His precious straw hat was no where to be found!

His frantic search for the straw hat caused the small boat to start dangerously rocking back and forth, nearly tipping over completely. The young boy had to grip the edges of the boat and steady himself to stop himself from falling over.

Okay, he didn't like this. This wasn't fun anymore.

At first he thought that maybe this mystery would lead to another cool adventure, but he was stranded alone in the middle of nowhere without even knowing how or why he was there, and his hat was missing.

Panic started to take over, and his heart started racing. He didn't know what to do. He was just going to wait for Nami and the others, but now that his hat was gone he was becoming restless. He couldn't wait, he had to move. He had to find his hat. Not having it with him was like missing a huge piece of himself.

While he was searching for his hat and hyperventilating, Luffy didn't notice the silhouette of a large ship slowly approaching him. It was only until the ship got nearer that he finally realized that there was a ship in front of him.

He looked up at the ship. It was still far away so he couldn't really see it properly, but he could see the dark crimson sails and a skull with crossbones imprinted on the front. The skull had some kind of weird swirly moustache. It was obviously a pirate ship.

Luffy's eyes widened as he saw this as his chance to finally get off this boat and find his nakama, who will hopefully know what happened to his precious hat.

The Oro Jackson was sailing along the beautiful, pristine ocean. It was a nice, sunny day, and most of the Roger pirates were out on the deck sparring, chatting or just simply enjoying the view of the ocean.

Somewhere on the deck, a large group of people were gathered around two teenage boys. One had a funny red nose and long blue hair in a ponytail, while the other had striking red hair and was wearing a straw hat.

The two seemed to be quarrelling about something, and the crowd was egging them on.

"THE NORTH POLE"

"NO IT'S THE SOUTH POLE"

"ARE YOU AN IDIOT YOU STUPID RED HEAD? IT'S OBVIOUSLY THE NORTH PO_ OWWWWWWWWW!" The two teens looked up in fright and held their heads that now sported a large bump. A blonde middle aged man was looking down at them, annoyance clearly written all over his face.

"Th- The vice captain!" they both squeaked.

"You idiots, south pole, north pole, who cares which one is colder? If you want to find out so badly why don't you go there yourself?"

The two teenagers instantly shut up and looked away, their cheeks flushing red in embarrassment as the crowd that had gathered around them was now laughing.

"We don't have time for your idiocy, we are nearing the island. Now stop messing around and go help with the preparations!"

"Yes sir!" The two quickly scrambled as far away as possible from the middle aged man.

The man sighed as a deep laugh echoed throughout the ship.

"Aw don't be such a meanie Rayleigh, the poor boys were only having fun". Rayleigh looked at the man he called captain from the corner of his eye in annoyance.

"We don't have time for this Roger, you know that! Whitebeard is waiting for us, we need everyone to carry out their duties".

"Gurahahahahahaha, that old man? Don't worry about him, he can wait." Rayleigh shook his head at his captain as a small smile crept on to his face. Even after all these years, Roger hasn't changed.

"Captain! I can see something out in the distance!" The lookout shouted from the top of the Oro Jackson's crow's nest.

Rayleigh perked up at the news "Hm? Is it the island? I thought we still had a day or two until we reached it".

"No, it's definitely not the island, it's way to small". The lookeout replied. "Hold on, let me take a closer look". The lookout got out his telescope from his pocket and used it to inspect the 'thing' that was out in the ocean. " Hmmmm let's see, it seems like it's a small boat. I think there is someone on it, though he seems to be moving around a lot for some reason, almost like he's searching for something".

The pirate king got a mischievous glint in his eyes at hearing this. "Ohhhh, maybe he needs help? Change the direction of the ship! Go towards the boat!"

"Aye aye sir".

"Wait a minute, Roger, we don't have time for this, we need to get to the island. Anyway, this could be a trap!" Rayleigh grabbed Roger's arm and turned him around to face him. He was starting to get really annoyed at his captain.

"Gurahahahahhahahaa! Come on, where did your sense of adventure go? Are you getting old Raleigh? I already told you, Whitebeard can wait. Besides, even if it's a trap we will still be easily able to kick the enemy's ass! And what if the poor guy really does need help?"

For what seemed to be the tenth time that day, Rayleigh sighed. He knew that he wasn't going to be able to change his captain's mind. This was going to be a long day.
