I love that all the actors got to use their real accents for the One Piece Live Action. It's a fictional world where the protagonist is a stretchy rubber boy, why can't the show sound like a hodgepodge of world accents? Some of my favorite things that I noticed about their accents:
kid!Luffy speaks with an American accent but grows up to speak with a Mexican accent while his grandpa is Welsh
Despite growing up in the same town and having known each other their whole lives, Kaya has a British-Cameroonian accent while Usoop has an American accent. Kaya is so rich that she sounds like she's from a different continent than her childhood friend
kid!Nojiko speaks with an American accent but grows up to speak with a Nigerian accent while Coco Village sounds British
Sanji speaks with a British accent but yells out his finishing moves in French
