As is fitting for a family of treasure hunters and pirates who live on a Hawaiian island, every member of the Rich family - except for Noah's pet Goro the tiger cub, of course, who got his name simply because he "looked like a Goro" - is named after a famous historical or mythological figure or media character associated with sailing and the ocean.

Pirate Yakuza in Hawaii's cosmetic outfits for Goro Majima are an excellent tribute to his previous roles in the series.
