In the Egghead arc of One Piece, fans saw quite a lot of focus being thrown on Jewelry Bonney. In many ways, it can be said that the Egghead Island arc was Bonney's to quite an extent. She played a major role in this part of the series, and she continues to be extremely important here. More recently, Bonney could utilize the abilities of her Devil Fruit to the full extent, and essentially, tap into the powers of Gear 5. Luffy taught Bonney how to use this power, and now, there are essentially two people with the power of Nika on Egghead Island.
