Bounties are an incredibly important part of One Piece and, from the very beginning of the story, this concept has had the fans excited, simply because it goes to show the level of importance a particular character has to the plot and, at the same time, tracks their progress over the years as well. When it comes to Luffy's bounty, fans have been fascinated by his incredible growth over the years and, currently, he is among the Four Emperors of the Sea with a massive bounty on his head.
