Over the course of the manga, Oda was often asked certain questions about the Straw Hats via the SBS sections. These questions were often about subtle information such as what colors represent the Straw Hats and other similar topics. The following are Oda's answers to such questions.
In an SBS question, a fan asked what animals would they best resemble. When this question was first asked, the Straw Hats had 6 members. At a later SBS, Oda provided the other animals for the remaining crew members. Chapter 651's color spread depicts each Straw Hat as an animal post-timeskip as well. Some members' animals are changed, (Zoro is depicted as a tiger but according to the SBS he is a shark) but some stay the same (Luffy is drawn as a monkey).
In relation to an SBS question about a shirt Nami wore with the number 3 on it, Oda showed the specific numbers that he uses to represent the Straw Hats. The majority of these numbers are different from the order Luffy's crew joined him. They are instead numbers representing the order of the Straw Hats as a whole. When this question was first asked, the Straw Hats only had 6 members. At a later SBS, Oda provided the other numbers for the remaining crew members. Note that the title of the chapter where a member joins is the ordinal number one less than the personal number; for example Zoro joins in Chapter 6, The First. Recently, each Straw Hat got another number, which determined by the order of who arrived at the Sabaody Archipelago.
In an SBS question, a fan asked if each of the Straw Hats have specific colors. Oda replied and revealed the specific colors for each member. When this question was first asked, the Straw Hats only had 6 members. At a later SBS, Oda provided the other colors for the remaining crew members. In the 17th opening, all the Strawhats wear clothes with color schemes appropriate of their color.
In an SBS question, a fan asked Oda that since Chopper had such an amazing blue nose that allows him to identify his fellow crewmates, what do they all smell like. When this question was first asked, the Straw Hats only had 6 members. At a later SBS, Oda provided the other smells for the remaining crew members. All but Chopper's smell were identified as Chopper cannot tell what he himself smells like.
Favorite Type of Island and SeasonEdit
In an SBS question, a fan asked which type of island do each of the Straw Hats like among the different seasonal types of islands in the Grand Line. It was also asked which season of that island do the Straw Hats like. When this question was first asked, the Straw Hats only had 7 members. At a later SBS, Oda provided the other islands and seasons for the remaining crew members.
In an SBS question, a fan asked what each of the Straw Hats' favorite food were. Oda gave the following as a reply:
As a FamilyEdit
In an SBS question, a fan asked if the Straw Hats were a family, what family member would each one be. When this question was first asked, Brook wasn't a member at the time. At a later SBS, Oda provided the answer to which family member would Brook be.
In an SBS question, a fan asks what would a genderswapped Straw Hat pirate crew be like, looking at Emporio Ivankov's powers. Oda replies with drawings and quotes for each genderswapped Straw Hat, all except for Brook who is just a skeleton and is unable to show any visible change.
[note: Except for Luffy (partly), Zoro and Sanji, they all say their own catchphrases, but modified to be extremely feminine/masculine.]
In an SBS question, a fan asked if the Straw Hats were real, what nationality would they be of. Based on their appearances, Oda gave the following as a reply:

In an SBS question, a fan asked Oda what are the Straw Hats' blood types. As a reply, Oda wrote:
- Note: In some countries they use the ABO naming system, which explains Crocus' blood type: X is equivalent to A; F is to B; S is to O; and XF is to AB.
- Note:The RH typing was not stated in the SBS, but can be derived as it is the only way for the story to work without plot holes.

In a SBS question, a fan asked about each crew members' strong points in terms of cooking.
Early One PieceEdit
In One Piece Green: Secret Pieces an early concept of the crew was revealed. No changes in particular are seen in Luffy, Zoro, and Nami aside from a few small ones; such as Zoro carrying a bottle of sake on his waist and wearing a dark shirt rather than a white one, and Nami's skirt being a little wavy rather than having straight cuts.
- Sanji was supposed to have a somewhat thicker goatee from the beginning.
- Usopp was supposed to be a vice captain/sniper that resembled his father more.
- Chopper was supposed to be more of a "realistic-looking reindeer".
- Robin replaced a man that was supposed to be more of a plant lover than a history lover.
- Franky replaced the original midget carpenter.
- Brook also was supposed to have a Cavalier hat, instead of his trademark afro.
- In the manga series "Rurouni Kenshin", the Straw Hats' flag design was used on a bomb to start a vengeance hit on one of the main characters of the series. Before writing "One Piece", Oda worked as an assistant to Nobuhiro Watsuki, the creator of "Rurouni Kenshin".
- In the "Scott Pilgrim" graphic novel series, the Straw Hats jolly roger appears on a painting of a ship at a party.
- In the final chapter of the Naruto manga series, the author, Kishimoto, includes the Straw Hat's Jolly Roger in the final scene as homage to One Piece. Conversely, Oda includes multiple references to Naruto on the cover of Chapter 766.
- All of the crew members have lost someone whom they loved in the past: Zoro lost his rival and friend; Nami lost her adoptive mother; Usopp lost his mother; Sanji lost his old family at the cruise ship; Chopper lost his father figure; Robin lost her mother, her civilization, and Jaguar D. Saul; Franky lost his mentor; Brook lost his captain and later on his crew; and Luffy thought he lost one of his brothers
- Currently, they have at least 200,000,000 in their possession, which is the value of the treasure they got from Thriller Bark.
- So far they are the only known pirate crew where each member has a bounty on their head.
- In the anime since the Post-War arc, all Luffy, Zoro, Usopp, and Robin's olive skin were changed to light skin (in Robin's case to very light skin, similar to Nami's and Sanji's) to match them as they are colored in the manga.
- In the SBS Volume 51, Oda said that the Yojijukugo which would best represent the crew is "Unprecedented in history".
- On Chapter 662, the paper Monet was reading, instead of showing a picture of Sogeking, it showed a picture of Usopp after the 2 year timeskip.
- The Straw Hat Pirates has the highest total bounty of any currently known pirate group.
