After the reveal of Gear 5 and the true nature of the Gum-Gun Fruit in One Piece, many fans now consider Luffy’s Devil Fruit one of the strongest in the series. Sporting an extremely powerful ability that is only limited by the user’s imagination, when Luffy is in Gear 5, few characters in the series could beat him. However, as many would expect, with Gear 5 being such a powerful form in One Piece, there are bound to be some drawbacks to make it not seem too overpowered.
