Marineford, for many fans, is an arc that represents a turning point in One Piece. Being an amazing war arc that uses the expansive cast and world of One Piece well, Marineford brings the series to an entirely different level than fans have seen before. Raising the stakes, taking emotional risks, and giving the series an overall darker tone are just a few of the things Marineford accomplishes, all while giving Luffy the perfect motivation to head into the post-time skip era.
