Zoro values loyalty highly and will not easily forgive fellow crewmates if they brake ties to the crew, first seen when Nami took the Going Merry Zoro was furious and stated that he never trust Nami in the first place, this happened again with Robin and Usopp, Zoro was weary of Robin questioning whether should they treat Robin as friend or a foe, and after Enies Lobby Zoro didn’t accept Usopp wanting to rejoin the crew saying he stepped on Luffy pride and he wouldn’t allow the Sniper back unless got down on knees and apologized for his disrespect to Luffy.
This dislike for leaving crewmembers was once shown once again in Zou this time over Zoro’s long standing rival Sanji, the Swordsmen was angry that the Cook had gone without so much apology or a “thank you for everything” calling Sanji a “idiot” for messing around with Big Mom when they already facing Kaido. This cold attitude towards crewmates is not appreciated by the crew and will provoke certain crewmembers (mainly Nami) to yell at him.
The same cannot be said when he is on the field of battle, though; he has been known to dodge bullets with ease. It has been stated more than once that Luffy’s instinct and behavior is similar to that of a wild animal’s, like when he knows who he has to fight before he even gets to the battle. Even his fights show this as he relies on his instincts and counter attacks.
This compliments the way he views the world. He is most often seen smiling, except in a fight where he is forced to use all his power (and sometimes even then). Luffy also seems to rarely change personality wise. Because he views the world in a straightforward and simple manner, he is occasionally the only person who can see past events that have taken place and realize the true goal, yet at other times he can fall into the simplest of traps.
Zoro has been good friends with Usopp since the start of their journey; Zoro was the one to tell Usopp to get on board the merry. Zoro finds Usopp cowardly nature disgusting and will always refuse Usopp request to be his bodyguard. Zoro and Usopp occasionally make idiotic decisions during a serious situation such as when they were fighting CP9 and got handcuffed together causing the swordsmen and sniper to run around in panic, Zoro suggested he cut off one their arms to which Usopp strongly disagreed.
So Zoro came up with a plan to use Usopp as his sword, this plan failed though they worked better together in the future. Zoro would not forgive Usopp’s desertion from the crew and disrespect towards Luffy and would accept Usopp back only if he bowed his head and apologised. When Usopp finally did this, Zoro was pleased to have him back.
While still a young boy attending a doctor’s academy in Flevance, Law was a very kind and devoted child, refusing to leave his family behind despite falsely promised evacuations at hand, and aspiring to become a great doctor like his father while happily going to festivals with his beloved family.
Upon the destruction of his homeland, the annihilation of his classmates and family, and diagnosed with no more than thirty-eight months to live, Law suffered a mental breakdown and, according to Doflamingo, came to be known for being very cruel and cunning, having wanted to join Doflamingo’s crew so he could destroy everything around him. Only after having been cured of his illness by Corazon did Law have a change of heart.
Sakazuki is shown to be very loyal to the World Government as many in the upper echelons nominated him to be Sengoku’s replacement as Fleet Admiral. Nonetheless, he was disgusted when he was informed the report given to Marine Headquarters about Doflamingo’s resignation from the Shichibukai was fraudulent. He even personally argued with the Gorosei concerning the matter.
He got very angry during his talk with the Gorosei and criticized how much work they issued because of Doflamingo. Sakazuki even insulted, provoked and mocked them because the CP0 acted over their heads, testing his limits and showing that, while he is loyal to the World Government, he does not agree with everything the Gorosei do, especially how little they care about the reputation of the marines.
Ever since Rayleigh had heard about Luffy from Shanks, he had wanted to meet him face to face. When Luffy found him on the Sabaody Archipelago, he was excited about hearing stories about Gol D. Roger. The more they talked, the more amused Rayleigh felt as he compared Luffy’s demeanor to his old captain.
He, like Shakky, has great expectations for him. After the war had ended, he swam across the Calm Belt to reach Amazon Lily, Luffy had been recuperating from his injuries and from the loss of Ace. From there, he helped Luffy break into Marineford with Jinbe in order for him to send the secret message to his crew. Rayleigh also mentored Luffy on how to master all three different forms of Haki he possessed.
Sabo’s dream involves traveling around the world as a pirate. This is in order to write a book containing the story of everything he would see and every place he would visit during his journey. One of the reasons behind all this could be the “segregation” that envelopes so much of the Goa Kingdom, a thing that could easily stir a freedom-loving spirit like Sabo’s to ask himself what the world was really like outside the walls of High Town, and outside the island itself. However, he was ready to cast aside his dream for the sake of his loved ones.
Sabo was loyal to his friends and, in this case his two “brothers”, to the point that he would give in to the demands of his father, becoming miserable and “alone” in order to save both Luffy and Ace. After reawakening his memories, Sabo did not leave the Revolutionary Army to resume his dream as a free-sailing pirate, as he seems to remain convicted to the Army’s causes.
