A/N I don't own One Piece. The start of this story won't make much sense due to the way I have set it up. I began writing this before the Big Mom Arc so I haven't included any of that in this story, this story may not deviate from cannon much but I will add some of the filler arcs

After the Straw-Hat Pirates had beaten Doflamingo that had received a mysterious call to meet the person on an island in the New World, the caller claimed that they had the rest of the Straw-Hats. So Luffy and Law decided to head there to see if it was true or a trap then to head to Zou. They were surprised when they arrived on the island they were instructed to go to find that it only had one large building. Luffy could feel his crewmates inside and charged in with the rest of the crew and Law only to fall into a trap, they were surrounded by a Sea Stone coated building that sapped the Devil Fruit user's powers. They then heard a voice come over the speaker discussing a experiment they had been conducting as the room started to glow and then the inhabitants disappeared.

12 Years ago

A strange light filled the sky as 10 beams of light broke off and shoot to different parts of the world. The strongest beam hit Foosha City and that is where this story begins, the beam hit a young boy standing on a ship with a knife in his hand about to stab himself in the face. The boy stabs himself under the eye much to the shock of the pirates. The captain of the crew quickly makes sure the boy is okay and takes him and his crew to the local bar.

The crew and the boy were partying and having fun, when a bandit entered the bar and demanded alcohol, upon learning that there was no alcohol left Shanks tried to give the bandit a bottle. The bandit breaks the bottle over Shanks head and then when Shank's started to clean up the alcohol the bandit breaks more bottles, showering Shanks straw hat in alcohol. It was at that moment that the future Luffy awoke in his past's body.

A strong wave of pressure familiar covered the bar and all the bandit passed out. The Red-Haired crew were shocked that someone had used haki in the East Blue when they noticed that the power had come from Luffy.

"Luffy, do you know what you just did" Shanks asked in shock.

"Yeah, Gramps helped me learn it after I accidently did it against a crocodile" Luffy said with a smile.

Knowing that Luffy's grandfather was Garp the Fist, they knew that it was possible that Garp taught him about haki. So, they went back to partying when they noticed that the chest in which they had their devil fruit in had fell to the floor and the fruit was missing.

"Luffy did you eat the fruit in the box" Shanks asked with worry on his face,

"Yeah, I did, it didn't taste too good" Luffy said as he went to leave only to get grabbed by Shanks and for his arm to stretch out.

"Luffy, that was a devil fruit, it's the Gomu Gomu no mi, you can't swim anymore" Shanks told the boy.

One Week Later

Shanks and his crew had arrived back at the quiet town of Foosha when they heard the commotion. They took of quickly and ended up outside of Makino's bar, when they arrived they took notice of the large amount of unconscious bandits on the ground with a little boy standing above them with a grin of his face.

"Hey Shanks, can I come with you know" Luffy asked.

"Luffy what did you do" Shanks replied with shock in his tone.

"Just what Gramps taught me" Luffy replied with a smile.

"Luffy you're just a kid, I can't take you with me" Shanks told him as he and his crew went into the bar.

Days Later

Luffy was standing at the port facing Shanks and his crew, Shanks took off his hat and placed it on Luffy's head. He made Luffy promise to bring the hat back when he becomes a powerful pirate. Luffy promised him that he would and the two parted ways.

Months Later

A marine ship was pulling into the port of Foosha Town; this ship was different than the normal marine ships, this one had a dog face on the front of it. When the ship stopped a giant of a man stepped off and headed off to a certain bar.

Upon arriving at the bar the man walked in and walked straight at little boy with the straw hat drinking juice at the car. He instantly picked the boy up and took him out of the bar.

"Gramps, what're you doing" Luffy asked as he was carried away.

"You're going to be living with someone new" Garp said as he took him into the mountains.

"Hey Gramps, can you train me" Luffy asked.

"Only if you become a marine" Garp replied thinking he had finally won Luffy back over.

"I'll think about it" Luffy said looking away from Garp.

"That'll do" Garp replied as he continued to a small home on the mountain.

With Zoro

Zoro had been sent back to Shimotsuki Village, he had been sent back too late to save Kuina. He had been disappointed that he couldn't save his friend, but knew that with the time he now had he could spend time strengthening his body and making sure his haki was as good as it could be so he could become the world's strongest swordsmen for the future pirate king. He decided that he would train for a few years and then convince someone to take him to Loguetown so he could get Sandai Kitetsu and Yubashiri.

With Nami

Nami had also arrived back in Cocoyasi Village too late to save Bellemere and decided that she would spent her time training after she worked out they were in the past. She decided that while working for Arlong she would travel around the East Blue and find as many ingredients to make her weather balls as she could and would also work on her Kenbunshoku Haki. When the time was right she would head to Orange town and prepare to meet her captain again.

With Ussop

Ussop had freaked when he realised that he went back in time, he had no idea what he was supposed to do and how to find out what his crew were doing. Although it didn't take him long to realise that he now had a second chance to sail with his crew. He quickly decided that he would build back up his body as well as working on different types of ammo for his slingshot and mastering his Kenbunshoku Haki. He wanted to make sure he was a dependable member of the Straw Hat pirates this time around.

With Sanji

Sanji had arrived back on the rock that him and Red Leg Zeff were stuck on, he knew that he couldn't convince Zeff to not eat his leg so he just decided that he would wait until they got off the island to start training. He knew that after he got off the rock that he would master both of his Haki and convince Zeff to help him perfect his cooking and hopefully teach him all he can about fighting. He would also work on building his body back up and strengthening himself to be one of the strongest members of his crew.

With Chopper

Chopper had arrived back in Drum Kingdom and instantly realised he was still living with Doctor Hiluluk, sadly he knew that he couldn't save the doctors life and he would eventually past. He decided that he would learn everything he possible could about medicine and would master his Kenbunshoku Haki. He decided that he was right to decide that if he was had his friends that he could be a monster for his crew.

With Robin

The time that Robin had arrived in was her working for Crocodile in Baroque Works. She decided that she would keep an ear out for the return of the Straw-Hat Pirates and would train to make herself strong for her crew. She had decided that she would work on mastering both forms of Haki and preparing herself for the eventual reunion of the Straw-Hat pirates.

With Franky

Franky had arrived back in Water Seven and started to work on making his body as great as he could. He worked on his Busoshoku Haki and decided that he would prepare the Franky Family for his eventual departure with the crew. He worked on making the Family legitimate ship dismantlers and basic shipwrights who worked for him and Iceburg. He knew that man would be able to take care of his family after he left for his dream.

With Brook

Brook arrived back in the Florian Triangle and decided that he would help keep crews out of Gekko Moriah's gasp while also sneaking onto his ship and battling his crew. He worked out this would make him stronger for his crew and he could work on mastering his Haki while he waits for the Straw-Hats to come pick him up. He decided that he would work on his sword techniques and be as strong as he could for Luffy when he arrived in the triangle.

END

Move List

Kenbunshoku Haki – Observation Haki

Busoshoku Haki – Armament Haki

I will also have a poll up to decide the Devil Fruit that Ussop will receive, I have put up two Zoan Fruits, one Mythical Zoan Fruit and a Logia. The poll will be closed just before the end of the Skypeia Arc. I am giving Ussop a Devil Fruit that I hope would improve his sniper skills in one way or another. This story will also involve a larger Straw-Hat crew as well as the Straw Hats making more alliances in the Grand Line. Luffy will be a bit smarter in this version but not by much, but he has been planning some of the things his going to do since he got back
