One Piece fans have been eagerly awaiting a new member of the Straw Hat Pirates. So far, the crew has ten members. The latest addition is Jinbei, who officially became part of the crew during the Wano Country arc.
Since the timeskip, there have been several characters who almost joined Luffy's crew, including Carrot and Yamato. However, no one really does. But fans have found a perfect candidate for the eleventh member of the Straw Hats in the current arc.
Jewelry Bonney plays a major role in the Egghead arc as Kuma's daughter and a target of the Gorosei – the Five Elders. She fights alongside the Straw Hats in this arc, but will she join Luffy's crew?
Bonney will join the Straw Hat pirates in the near future to escape Egghead Island. However, as of yet, we do not know whether she will become the eleventh member of the gang or not.
With the events of the Egghead arc, Bonney will be joining the Straw Hats and following the giants to Elbaf. It's her only way out now, with the Gorosei chasing her and Kuma's lives. So she'll also play a major role in the upcoming Elbaf arc.
On top of that, she made friends with several members of the Straw Hat crew. Sanji and Zoro have protected her many times from the Gorosei, and she has a good relationship with Jinbei, Chopper, and Franky. But what makes Bonney joining the Straw Hats interesting is her relationship with Luffy.
The Straw Hat captain always has a warm friendship with children, as we saw in Wano, that is with Momo and Tama. It makes sense that he would form a similar relationship with Bonney. Besides, they are both voracious eaters and were once part of the Supernova generation.
Most importantly, Luffy is the latest avatar of the Sun God Nika, whom Bonney has loved and revered since she was a child. She sees him as the epitome of freedom and finds encouragement through him.
After witnessing Luffy's Gear 5 in chapter 1118, Bonney gained a new transformation, where she mimics a form similar to Gear 5. She calls this “Distorted Future: The Future Where I Am Freest”. However, this form is much weaker than Luffy's Gear 5 despite the two looking very similar.
As seen in One Piece chapter 1119, Bonney can only maintain this Nika form for a short time. After that, she becomes so weak that she cannot maintain her adult form, reverting back to a child.
If she joins the Straw Hat Pirates, Luffy could become her mentor. Although their Devil Fruit powers are very different, he could teach her how to use her Nika form better and longer. His guidance would also help her gain confidence and protect her from the World Government.
However, we'll have to wait until the end of the Egghead arc to see if Bonney actually becomes the eleventh member of the Straw Hat crew.
