A different reader had the same question and according to Oda, it was all because of Usopp's bad influence. Luffy and Usopp are of the same. OP: We will Meet Again. But of course, Luffy and Hancock's relationship is a whole lot more deep, yep I hope they will meet again soon <3. Our first candidate is Lola, who Luffy and the crew met back in Hancock delivers him to Sabaody Archipelago to meet back up with his crew.
Some of them even root for him as a worthy candidate for the next Pirate King, and being part of his crew meant some shared glory in the future. He appropriates them as extensions of himself, his "hands" and "legs".
His orders are to find and crush the real Straw Hats that humiliated him. Luffy speaks to the fakes assuming them to be the real ones yet noticing that they are more friendly than he remembers. The fakes call for their captain's attention, and the target, Luffy, stands before his eyes. Unfortunately, the Marines and his former managers have flanked him. The Marines confirm him as "Humming Brook" with a 33, bounty and a member of the Straw Hat crew.
Brook's fans become distressed at the news, while others were silently musing that Brook should be granted leniency, even if he truly was a member of the Straw Hats, since that crew of Pirates were long thought to be dead and gone.
His managers explained that by honestly telling them that Brook would be retiring, it would be the end of the business exploit hence inciting them to have Brook die with them. In fact, this incites Brook to call on his band and dancers in helping him declare that the rumors were false.
Ridiculous--Tell This to the World.

The Marines are held by the fans as Brook rocks the concert ready to go to the New World. The Straw Hats reunite with Franky. Back on the Thousand Sunny, newly refurbished, Nami, Usopp and Chopper meet up with the rest of the crew. Usopp holds Chopper as he gawks at the new upgrades on Franky who now sports concealable hands within his giant ones and a hair-frizz feature.
Nami is overjoyed to see the real Robin again and, to a shyer extent, the real Franky. Rayleigh and Shakky show up.
Shakky updates the current crew on deck where the others are and the situations on the archipelago. Rayleigh heads to Nami intent on teaching her how to navigate a coated ship.
Usopp, worried since Luffy has not shown up, asks about him. Rayleigh replies with a smile on his face that Luffy has already disembarked. Edit Meanwhile, in Grove 33, one of the Marines report in that they are unable to capture Brook as the crowd has held them back and the musician had run off during the chaos. We soon find that he was with the Flying Fish Riders who comment that Shakky told them to pick him up. Brook is more than grateful and excited to reunite with the Straw Hats.
In Grove 41, Franky contacts Sanji with Zoro, telling him where to meet up. When Zoro asks what going on, Sanji slowly spells it out for him causing a brief argument. However it's interrupted when they notice some noise coming from a nearby island.
In Grove 46, the Fake Luffy is about to sic his pirates on the real Luffy, commenting that it'll serve as a warning to whomever crosses him while Luffy asks Fake Zoro and Fake Sanji if he Fake Luffy is a friend of theirs. Before anything can happen, the Marines arrive and surround the pirates, ordering Fake Luffy's surrender. Fake Luffy orders Caribou and Coribou to use the Marine they wounded earlier as a shield to make an exit.
Caribou however comments that it's too tall an order and kills the Marine right then and there, claiming it was punishment for lying about not calling the Marines. Pacifistas attacking the recruits of the Impostor Straw Hat Crew.
A PROMISE BETWEEN FRIENDS – LUFFY PLANS TO MEET THEM AGAIN | ONE PIECE GOLD
With their bargain chip gone, the Marines rush the pirates who attack in kind. The real Luffy wonders what the heck going on as his fake self quickly loses control of the situation. If that is not bad enough, the Pacifistas arrive and begin shooting at the pirates. Doughty is caught in the blast and knocked out, surprising the pirates that an 88, bounty did not stand a chance.
They soon start calling for "Luffy" to help them. But the Fake Straw Hats and he are fleeing the scene knowing they do not stand a chance. It does them little good as they are confronted by Sentomaru and a Pacifista. The pirates believe that the Fake Luffy will easily defeat them. The Fake Luffy nervously tries to threaten the Marine captain but is quickly hammered into the ground and taken out much to his crew's surprise.
Sentomaru realizes that the Fake Luffy has tricked the pirates present and orders the Pacifista to identify him. Their ruse exposed, the rest of the Fake Straw Hats make a run for it while their now former subordinates are outraged at being deceived.
The real Luffy quickly figures out what going on too, though comments that "Zoro" and "Sanji" looked like the real deal.
Sentomaru orders the arrest of every pirate there, commenting he knows the real Luffy is in the crowd and has his Pacifista aim for him. Luffy manages to jump away as the other pirates are caught in the blast. However his disguise is knocked off, revealing himself to everyone in the area. The Fakes foam at the mouth when they realize they had actually threatened the real deal. The Marine quickly runs in while Sentomaru confronts Luffy, ordering his Pacifista to fire another shot.
Zoro and Sanji defeat PX Luffy however, dodges the blast and goes into Gear Second then takes to the air and hits the Pacifista as it tries to fire again, knocking it out in one hit. Everyone is shocked by the feat, Sentomaru especially as he noticed that Luffy had Haki equipped. As Luffy leaves the area, he sees the real Zoro and Sanji running towards him.
Return to Sabaody Arc
However another Pacifista gets in their way and prepares to fire. But both instantly hit it their attacks, both cutting and breaking Pacifista's neck in the process.
The pirates soon realize that these Straw Hats are indeed the real deal. As Zoro and Sanji prepare to exit the area, they notice Luffy has not moved yet. Luffy yells out to Rayleigh who is on a far off hill observing the area and making sure Luffy was alright. Luffy thanks him for everything for the last two years and yells that he is gonna be the Pirate King. The pirates are left speechless while Sanji, Zoro and Rayleigh just smile, the latter with tears in his eyes. The Marines closing in snaps Luffy back to attention and he continues to run, thanking Rayleigh one more time.
Rayleigh, remembering their training together, tells Luffy to go straight for the top. He then gets in the Marines' way and draws a line in the ground, warning them not to cross it. Meanwhile Luffy, Sanji and Zoro continue to flee but find themselves surrounded by more Marines.
However negative ghosts suddenly appear and stop them, revealing Perona, now much more grown up, to the trio. She chides Zoro when he ask why she still there, revealing that she was the one who brought him to Sabaody.
She then warns the three that Marine ships are near the island. The Straw Hat Pirates reunite. Back in Grove 42, Brook has reunited with the other Straw Hats on the Thousand Sunny, immediately asking to see Nami's panties once on board and once more getting kicked for his trouble. Chopper soon arrives back, having gone on to get Luffy, Zoro and Sanji using the bird from Torino Kingdom. The group is more than overjoyed to see their captain after so long.
Sanji is especially happy to see Nami and Robin, so much so that he gets a gushing nosebleed which Usopp ordered Chopper to fix. Luffy then starts to marvel at Franky's new body but Nami tells him it is not the time. Marine ships suddenly arrive and start firing cannonballs at Sunny. But they are suddenly stopped by Slave Arrows. Hancock's ship gets in front of the Marines, forcing them to stop firing.
Hancock demands to know why there is a Marine ship in their path and winks at Luffy, obviously creating a diversion for him. The others are surprised that a Shichibukai is helping them. Luffy explains that she a friend of his earning Sanji's jealousy. Franky opens the valves under the ship, letting air into the coating jelly and expanding it, turning it into a giant dome that covers Sunny's deck.
As it does, Usopp notices that no Marines from the mainland are chasing them anymore. It is soon explained why as the Straw Hats' allies from during their separation are keeping the Marines at bay. Heracles uses giant horned beetles against them, wishing Usopp luck on his journey. Haredas and his fellow weather scientists manufacture rain over the island, soaking the Marines' gunpowder.
Perona uses more of her negative ghosts on the Marines. The okamas are dealing with another bunch of Marines, trying to break their hearts. As all this goes on, Nami explains how coating works. Telling the crew it works against water pressure but the ship will no longer be buoyant. Once the floating bag is removed, the ship will sink.
Franky then removes the bag and Nami order everyone to raise the sail much to Usopp's confusion. Though Robin explains that the underwater currents work like wind on a coated ship. Once Luffy is told they are ready to leave, he thanks the crew for putting up with his "selfish wish" for the last two years.
With that the Thousand Sunny heads underwater. The crew on the Marine ship frantically try to get their captain to go after them but he too smitten by Hancock to notice. Luffy then gives the order to set sail and the Straw Hats, reunited after two years, continue their journey to the New World.
Story Impact Many characters make their first appearance after the timeskip.
The characters in the order they were reintroduced are: After saving Lola and hers from Gecko Moria, the Straw Hats form a close bond with them and promise to meet up with them again one day. Still, this is pretty flimsy conjecture, hence she is my first example. After Luffy defeated Don Krieg, his attitude rubbed off on Gin and gave him a new lease on life. As Gin forces Krieg to retreat, he leaves Sanji with a message for Luffy: As Luffy departs from Fishman Island, Shirahoshi asks him to return and show her even more of the world.
This scene is given the kind of attention that just screams foreshadowing, so we can say pretty definitively that Luffy and Shirahoshi are going to meet again, and even the promise itself, to take her above the waves, would be fulfilled quite nicely with her on the crew proper. However, Shirahoshi is no fighter, and while her ability as Poseidon to control the Sea Kings is incredibly powerful, its use is also rather limited to the sea.
Still, if she were to join, her role on the crew seems pretty clear; controlling the Sea Kings to act as guides. After Luffy spent two years training on Rusukaina, Hancock delivers him to Sabaody Archipelago to meet back up with his crew. Also, as I said with Lola, Hancock has her own crew, and more than that, she has her own kingdom to take care of.
She seems much more likely to become a Fleet Commander, and this scene may also serve as foreshadowing for another Kuja joining possibly Marguerite.
