Luffy is the son of Monkey D. Dragon and he was raised in Foosha Village. Originally his grandfather Monkey D. Garb the vice admiral and the hero of the Marine wanted Luffy to become a strong Marine soldier; However, when Luffy was 6 years old he met the Red Hair Pirates and their captain Shanks. He was motivated by them to become a pirate and have his adventures in the sea just like them. Accidentally he got his hands on the devil fruit owned by the Red Hair pirates and he ate it. As a result his body became rubber and lost the ability to swim.
One day he was kidnapped by mountain bandit Higuma. Higuma tried to throw Luffy into the sea when suddenly a sea monster appeared and ate Higuma right after he threw Luffy into the sea. The sea monster was about to eat Luffy as well but Shanks showed up and saved Luffy at the last moment with the cost of losing his left arm to the sea monster.
After this incident and after the departure of Red Hair Pirates, Garb has taken Luffy to live with the mountain bandits. There he met Ace and afterwards he met Sabo as well. The three of them became sworn brothers aiming to be pirates. By the age of 17 Luffy finally sailed out to see to become a pirate and has his own pirate crew.
His Dream is to gather a crew good enough to sail the sea and to find the greatest treasure One piece once owned by the late king of the pirates Gol D. Roger which will make him the next King of the pirates. Originally he wanted to have 10 members in his pirate crew and his goal to be the king of the pirates is because he will have the freedom he desire.
Luffy bounty has went through many changes over the course of their journey:
Zoro came to the dojo in Shimotsuki Village claiming he is a "Doujouyaburi" ( A person who challenge a dojo and defeats all of it's members). Zoro also claimed at that time, He has defeated everyone from the nearby villages, then he made a deal with the dojo's Master Koushirou that if he win he will take the signboard and if he lose then he will join this dojo.
Koushirou didn't fight against Zoro by himself, instead he called for his daughter Kuina to fight against Zoro. In response to Zoro's disappointment that he won't fight against the dojo's Master, Koushirou assured him that Kuina is very strong her self and stronger than the adults in the dojo. Zoro picked a lot of the bamboo swords in both hands and in his mouth, but he was easily defeated by Kuina. During the fight he admitted that this day was the first day he had held a bamboo sword. After his defeat he swore a promise to her that he will train and one day he will defeat her.
He kept training every day to achieve his goal. In one year, his skills and strength increased tremendously since their first duel and he became the strongest among male students and even able to win against adults, yet he still lost to Kuina 2000 times without a single win. In the night of his 2000th defeat, Zoro challenged Kuina again but this time with real swords and stating this would be their last duel. After a long fight with real sword, Kuina won again.
Zoro cried and said he doesn't accept this at which Kuina told him she is the one who can not accept this, because she also share the same dream as Zoro to become the strongest swordsman; However, her father told her being a girl she will never be able to achieve that goal. Zoro was pissed when he heard that and told her to make a promise that either one of them will become the world's greatest swordsman. They made that promise to each others on that night.
The next day Zoro decided that two swords are not enough and he will use three swords. While he was training the other dojo students came to him carrying the sad news of Kuina's death. After her death he asked Koushirou to have Kuina's sword Wado Ichimonji. Koushirou agreed and entrusted Zoro with Kuina's sword and dreams. Eight years later, Zoro started his journey to become the strongest swordsman in the world with his own three swords style. Using a sword in each hand and holding Wado Ichimonji in his mouth.
Before joining the straw hats, Zoro was known as a Pirate hunter. It wasn't his goal to become a pirate hunter but it was a source of income for him to buy food and fix his swords. At Shells Town, Zoro saved a girl called Rika from the Helmeppo's pet wolf . Helmeppo is the son of Marine Captain Axe-Hand Morgan and he tried to attack Zoro but easily got defeated by Zoro. Helmeppo threaten that his father would kill Rika and her mother, so instead of that he made a deal with Zoro that if he accepted to be tied up to a post for a month no one would get hurt which Zoro agreed to.
On the ninth day of Zoro's restraint, Luffy arrived and asked Zoro to join his crew and got rejected. Afterwards Luffy learned that Helmeppo doesn't plan to keep his promise and instead he plans to kill Zoro. Luffy came back to Zoro and said "If you want your Katana back you will have to be my nakama" then he went to bring Zoro's swords from the Navy base. He came back just in the neck of time to save Zoro from being executed. Luffy offered Zoro to join again at which Zoro agreed as he preferred to be a pirate than die here. Luffy gave Zoro the swords and they both fought the Navi and won the battle against Axe-hand Morgan.
Zoro has a dream to find and defeat Hawk eyes Mihawk whose number one swordsman in the world. He aims to take his place as the strongest swordsman in the world.
There was a war at Oykot Kingdom where the Navi were involved in a war against pirastes. Once the battle subsided, one of the Navi soldiers called Bellemere was heavily injured during that war and she was about to give up when she heard the sound of a crying baby. She opened her eyes and saw a little girl called Nojiko carrying a baby girl in her hands with orange hair. Nojiko wasn't related to Nami nor she knew her before, she just found her. Bellemere decided to take both of them and raise them as her daughters in Cocoyasi Village.
Nami as a child she had interest in drawing maps and sea charts. She also got interested in navigation, but she never been able to buy the navigation books she wanted because Bellemere was poor, so Nami ended up stealing the books from the village's bookshops. When Nami got caught stealing, she got scolded by Bellemere, yet she commended Nami for her first drawing of the island. Also, because Bellemere didn't have enough money to buy new clothes for Nami and Nojiko being older than Nami by two years, Bellemere would always give Nojiko's old clothes to Nami.
One day Nami got into an argument with Nojiko about having Nojiko's old clothes passed on to her. Nami ended up saying they are not even real sisters and not related by blood. This triggered Bellemere and caused her to slap Nami for saying that and scolding her about it. Nami replied that she wish a richer family had adopted her. That's when Bellemere told her if she doesn't like it in this house she can leave, and that's exactly what Nami did.
Bellemere regretted her actions and asked Nojiko to go and bring Nami back, while she prepares Nami's favorite meal for dinner. Nokiko has found Nami and told her about what Bellemere said. Both were happy going back to Bellemere's house on the outskirt of the village. This is when Arlong pirates has arrived, a pirates crew of fishmen from the grand line. The mayor of the village Gen told both Nami and Nojiko to hide as it's dangerous for them. Arlong came into the village stating that they have to buy their lives from him each month from now on, and whoever can't pay, will die. They have collected the money, and as they were leaving they noticed Bellemere's house because of the smokes coming out while she was cooking, and the pirates went after that house to collect their money as well.
Both Nami and Nojiko rushed back to Bellemere's house, however, The doctor of the village has stopped them just before they arrive to the house. He explained to them that because they are not officially recorded as her children, she wouldn't have to pay for their lives, and she barely had enough to pay for herself; However, after Arlong crew took the money she told them it's for her two daughters and she doesn't have enough for herself. Arlong killed Bellemere in front of her daughters, and ended up taking Nami after they have seen her skills at drawing maps. Eventually forcing Nami to join his crew.
At first Nami joined as the navigator of straw hats but only to steal from them. At the sea restaurant she took the ship and went back to her village because when she was a child Nami was forced to be part of the Arlong pirate crew. She had a deal with Arlong to buy her village for 100 Million. She has been stealing from pirates and saving the money to achieve that goal. When Luffy and the other found out about her story and how much she suffered in order to protect the people of her village they decided to help her. Luffy and the others went to Arlong Park and fought against Arlong pirate crew. Once Luffy defeated Arlong he shouted out loud: NAMI, YOU ARE MY NAKAMA. Nami nodded saying yeah with tears in her eyes and officially joined the straw hats as their navigator.
