It is a well known fact that the Straw Hat's have a Royalty member in their crew which is Vinsmoke Sanji of the Germa Kingdom. But what if there is another member born from Royalty? Here is the Possible members who are born from Royalty: 1. Monkey D. Luffy 2. Roronoa Zoro 3. Nami 4. Nico Robin 5. Brook Monkey D. Luffy - Possibly! Family background is very well known except for his Mother (which could be a royalty) Grandfather Monkey D. Garp is a Vice-Admiral and Hero of the Marines, Father Monkey D. Dragon is the World's Most Wanted Man and Leader of Revolutionary Army, 2 Adoptive brothers Portgas D. Ace 2nd Division Commander of Whitebeard Pirates and Sabo Revolutionary Army Chief of Staff and Adopted Mother Curly Dadan Mountain Bandit Boss. Only few hints of luffy's mother. Oda speaking about Luffy’s mom in an interview: (Source) “D: What is Luffy’s mother like? Was she beautiful? What happened to her? Did she die when Luffy was a baby? O: I think she’s alive. I’m still thinking hard about this. [Laughs] But if she does appear in the story, then she’ll be a very tough-looking woman. And strict. There’s no way that she’s a beautiful mother. She’s got this typical middle-aged woman’s permed hair. Speaking of families, I did a backstory for Nico Robin and her family. That was actually the first time for me to draw a mother in a character’s memory. Up until that point, I’d never drawn a blood relation. In Chopper’s case, he’s called a son even though he’s not blood-related. So I’ve put in a message there saying that you can still call someone who’s not related by blood your family.” In SBS volume 44, we had this question about Luffy’s parents. “D: Oda!! I have a serious question. Won’t you draw Luffy’s parents? -Mr. Uni – 16 Years Old O: His parents… they’ve already been drawn. They’ll appear in the next volume. Look forward to it ~” Roronoa Zoro - High Possibility! Family background Unknown. Nami - High Possibility! Family background War orphan, Adopted mother Bell-mère and Nojiko non-biological older sister. Nico Robin - Possibly! Family background Mother Nico Olivia Archaeologist of Ohara. Father Unknown (could be royalty). Brook - Possibly! Family background Unknown. I only pick this 5 members as they still have some unknown and mysterious family background than the other members, which some of them or not could be of Royalty. What DO you think?
