Episode 1153 of One Piece shocked fans by revealing not only Haki but also the silhouette of Joy Boy. However, this figure, strikingly similar to Luffy, clashes with the giant Straw Hat Imu keeps. If Joy Boy isn’t a giant, then who does that massive hat belong to? Is this an oversight by Oda or a clue pointing to a forgotten heir of Joy Boy?
Who owns the giant straw hat Imu possesses?

Imu’s appearance marked a historic moment in One Piece, confirming the ultimate enemy Luffy must face. The key detail is that Imu holds a giant Straw Hat preserved in ice at the Pangaea Castle (first seen in episode 885). This giant hat closely resembles the ones worn by Luffy, Shanks, and Roger, hinting at a complex connection between Imu and the series’ main characters.
The giant straw hat was first shown sealed in ice within a secret room of Pangaea Castle. Subsequent story developments sparked speculation that this hat might belong to Joy Boy, given his deep ties to the Void Century and Imu.
However, Joy Boy’s silhouette in the latest episode disproves this theory, as he clearly is not a giant. Instead, his build closely matches Monkey D. Luffy’s, suggesting Joy Boy was likely of normal size. The only logical conclusion is that the giant straw hat Imu holds does not belong to Joy Boy, implying another character, possibly a giant, plays a significant role in the Void Century.
Luffy’s straw hat is not Joy Boy’s

The Straw Hat storyline is one of the most meaningful aspects of One Piece, linking legendary characters across generations. Many fans believed Luffy’s straw hat was the sole physical item passed down from Joy Boy.
Recent developments have confirmed otherwise. There are at least two straw hats in the series: the giant one held by Imu and the one Luffy inherited from Roger and Shanks. This confirms the straw hat is more than just an object, it symbolizes the Will of Inheritance, freedom, and defiance against supreme powers like the World Government.

Luffy’s straw hat might be a later reproduction or a different version of the same symbol. The existence of multiple straw hats suggests there were several heirs who challenged Imu and the World Government’s rule but ultimately failed.
If true, this revelation would reshape One Piece’s story, unveiling a tragic line of heirs with Luffy as the final beacon of hope.
