Iñaki Godoy, the star behind Monkey D. Luffy, in Netflix's One Piece, opened up about what he felt was Luffy's greatest power! One Piece debuted last Summer as one of the most successful live-action anime adaptations released in recent memory, and it was a pretty big deal for Netflix too. One Piece's live-action series was massively popular with fans old and new alike, and a large part of that success was due to the fact that the main cast behind it all seemed like the perfect actors to help bring Luffy and the Straw Hat crew to life.
