Dreams

Each member of the Straw Hats has a dream they want to achieve. These dreams are their reasons for joining Luffy's crew, and essentially the driving force behind their lives. Each Straw Hat's dream was inspired by tragedies (often deaths) in their childhoods that involved at least one person they idolized and cared for deeply.
Some, like Zoro, Nami, Usopp, Chopper, and Franky are fulfilling their dreams by accumulating knowledge and/or achieving a certain task while sailing the Grand Line. Others, like Luffy, Sanji, Robin, and Brook are searching for a person, place or thing that can only be found on the Grand Line.
Whatever the reason, each of the Straw Hat's dreams involve traveling the Grand Line, and each Straw Hat member refuses to die before achieving their dreams. However, their determination doesn't extend to sacrificing or abandoning their comrades for the fulfillment of their dreams.

Members' DreamsEdit

• Luffy's dream is to become the Pirate King and gather his own pirate crew to back him up. To become the Pirate King, he must find Gol D. Roger's famed treasure, One Piece, which is implied to be on Raftel. As for a crew, he has brought together so far eight people who have caught his attention. Luffy is also looking to meet up with Shanks again and return his straw hat to him, but will only do this after his crew has surpassed Shanks' crew in strength.

• Zoro's dream, shared with Kuina, is to become the world's greatest swordsman. To fulfill this dream, he must surpass every swordsman in the world, including the world's current greatest swordsman, Dracule Mihawk.^[4] Zoro nearly gave up his dream in an attempt to convince the Shichibukai Bartholomew Kuma to refrain from killing Luffy despite that the first time they met Zoro threatened to kill Luffy if he got in the way of his dream, proving his loyalty towards his captain as well as the rest of the crew, as he believes that he cannot be the world's strongest swordsman if he cannot protect his captain's dream (Luffy, likewise, believes that the Pirate King should have the best swordsman on his side).

• Nami's dream is to draw a map of the entire world. She has already mapped all the areas that she has traveled, and it can be assumed that she will create a world map once the story is over. Also at the beginning of the story, she was also trying to get 100,000,000 in order to buy and save her hometown, Cocoyasi Village, from the clutches of the Fishman pirate Arlong; while her savings were confiscated after stealing 93,000,000, in the process of stealing from pirates, she met Luffy, who defeated Arlong and freed the village.

• Usopp's dream is to become a brave warrior of the sea like his father, Yasopp. Although he has implied that he has accomplished this dream (before he leaves the crew), Usopp has a second dream. After the Little Garden Arc, he also developed a secondary dream to visit Elbaf and see the warrior giants he idolizes. During the Post-War Arc Usopp develops another dream, to be the true Sniper King after he got Luffy's message to get stronger in two years.

• Sanji's dream, shared with Zeff, is to find All Blue, a legendary ocean. It is assumed to be in the Grand Line, a place where all waters from all over the four seas gather, bringing fish from all over the globe. During the early-Arlong Arc, Sanji had stated that he wanted to visit Fishman Island someday to see a Mermaid, which has recently been fulfilled; sure enough, the chef broke down crying upon seeing all the mermaids and implied that meeting the mermaids was on an equivalent level to finding the All-Blue. He also wished to consume the Suke Suke no Mi but unfortunately for him, Absalom destroyed that dream as he had already eaten it. However, Sanji, upon seeing Absalom's detestable actions, changed his mind about his desire to consume it.

• Chopper's dream is to become a great doctor that can cure any disease, much like his father figure Dr. Hiluluk's ambition, as well as to travel across the world, exploring with his friends, and expanding his horizons.

• Robin's dream is to find the Rio Poneglyph which tells the True History, continuing the research of her mother Nico Olivia and her old mentor Clover.

• The Going Merry's dream as the crew's ship was to sail with the Straw Hats forever which it revealed to the crew upon its demise. In the end it was a dream it could not achieve, it was last seen as it was given a Viking funeral (because the "bottom of the sea is dark and lonely"). However, Merry's spirit supposedly inhabits the Straw Hats' new ship, the Thousand Sunny, and therefore its dream may live on through it.

• Franky's dream is to create and travel with a dream ship which would experience countless battles, can overcome extreme hardships and can reach the end of the Grand Line. He has created the ship which the Straw Hats are riding and it's his task to keep it in good condition. Previously, one of his dreams was to beat Spandam to pieces, but this was fulfilled toward the end of the Enies Lobby Arc.

• Brook's dream is to return to his crewmate Laboon, whom his former crew, the Rumbar Pirates, had left behind at Reverse Mountain for his safety, with the promise to return after crossing the Grand Line. He wishes to fulfill that promise to Laboon, as well as that of his former crewmates, who died at their journey, to deliver their final song recorded in a Tone Dial before their death.
