During the thrilling climax of the Egghead arc, Bonney channeled Nika’s form to battle alongside Luffy against St. Saturn. Although the name “Joy Girl” is not officially recognized by Oda, fans have embraced it as affectionate tribute for Bonney’s transformation. It’s essential to note that Joy Girl and Joy Boy are distinct characters within the series, something that might have confused early fans. So, you may wonder how Bonney managed to attain this form when Luffy is already seen as the Nika of this era. Let’s explore that further.

You might be curious how Bonney emerged as a second Nika in the narrative. The key lies in her powerful Toshi Toshi no Mi (Age-Age) Devil Fruit. Initially perceived as a fruit that only allowed Bonney to manipulate her own and others’ ages, it also grants her a fascinating ability known as Distortion Future. This unique power enables her to access any desired future form, granting her remarkable flexibility in combat. For instance, while evading Alpha, Bonney transformed her small hand into a gigantic fist, reminiscent of Luffy’s Gear 3, to deliver a punch.

Fast forward to the Egghead arc, Bonney finds herself amidst a critical conflict. While attempting to escape with the Straw Hat Pirates, she encounters St. Marcus Mars and St. Saturn. As Luffy activates Gear 5, Bonney expresses her doubt about keeping up with someone like Nika. Luffy responds with encouragement, which empowers her to reevaluate her capabilities. Remembering that Luffy’s Nika form symbolizes his ultimate freedom, Bonney channels her Toshi Toshi no Mi powers, achieving a form that mirrors her authentic self—thus, the birth of Joy Girl in One Piece.

Fans can expect to see Bonney’s transformation into Joy Girl featured in One Piece Episode 1151, titled “The Dream I Envisioned With Dad!

There has been some concern among fans regarding Bonney’s ability to so seamlessly replicate Luffy’s Gear 5 form using her Distortion Future technique. Thankfully, Oda emphasized the significant limitations of Bonney’s Nika form. One crucial point is that she cannot sustain this alternate future form for an extended duration.

Bonney herself acknowledged that maintaining the Joy Girl form is particularly taxing, causing her to revert to her normal kid form after assisting Luffy against St. Marcus Mars and delivering a strategic Nika Punch against St. Saturn in the Egghead arc’s climax. Expect Bonney to remain in her Nika form for a few episodes before the energy drain forces her back to her original state.
