Episode 1152 of the One Piece anime just aired and stirred up the community with Luffy’s emotional moments protecting Bonney. Amid the chaos, Toei Animation cleverly revealed an important detail about Joyboy’s appearance. Based on the manga, many believed Joyboy had a prosthetic arm or a hook. But in the anime, that arm looks exactly like a normal human arm, putting to rest the classic pirate hook theory.
Joyboy’s Appearance: What We Know So Far

When Joyboy’s silhouette first appeared in the manga, it sparked a big misunderstanding about his image as a classic pirate: an arm resembling a hook. However, episode 1152 of the anime clarifies this detail.
Joyboy’s arm clearly looks like a normal human arm. While it could still be a robotic arm designed to look natural, the speculation about a traditional pirate hook is dismissed. Eiichiro Oda definitely avoided the stereotypical pirate look for this historical figure.
For now, while the arm is clarified, the question about Joyboy’s leg remains open. The manga hints he might have a wooden leg, but episode 1152 does not officially confirm this yet.
Although only appearing as a silhouette, this is the only time Joyboy has appeared up to the adapted chapter 1122. According to Emet (the Iron Giant), Luffy in Gear 5 form bears an incredible resemblance to Joyboy.


In the revealed silhouette, Joyboy wears a wide-brimmed Straw Hat very similar to Luffy’s and closely resembles the giant frozen hat at Mary Geoise. His outfit includes shorts and a cloak or jacket, somewhat reminiscent of Ace’s look. These clothing and hat details are not mere coincidence but strongly reinforce the deep connection between Joyboy and Luffy, not only in power but also in style and legacy.
Toei Animation’s Skillful Manga Adaptation


It’s clear Toei Animation holds behind-the-scenes information fans don’t have. Eiichiro Oda may have confirmed that Joyboy’s arm is not a hook, which is why Toei confidently changed this detail.
If so, the anime’s subtle adjustments and clarifications that the manga never directly addressed are fascinating. Every small change, frame shift, or added detail in the anime could be a deliberate clue from the creator, revealing the true appearances of mysterious characters.
Although everything currently remains in silhouettes and interpretations, Toei Animation’s careful and meticulous manga adaptation suggests we can expect more intentional changes in the future, not just for Joyboy but for other characters and events.
Fans’ anticipation grows with each episode as the line between manga and anime becomes harder to distinguish.
