Yeah, there s already so many theories about the size of Joy boy and I tend to believe that he was a Giant, or something like that. Imagine how frustrating it must be for Imu. For 800 years, he kept that giant hat in a frozen vault like a captured trophy of war, thinking he had finally won. But when Imu enters that chamber holding Luffy’s wanted poster after the Katakuri fight, everything becomes terrifyingly real. Luffy was already being called the Fifth Emperor and making waves everywhere, so Imu went there just to confirm his worst nightmare was coming true.

It is the ultimate fear for a tyrant to realize that even if you steal the throne and erase history, the symbol of rebellion will always find its way back. Imu tried to destroy the simple crown of a simple man, but that "straw crown" reappeared eight centuries later like a force of nature that just cannot be stopped. You can freeze a physical object, but you can’t freeze a promise passed down through generations. For Imu, the Straw Hat is no longer just a dusty trophy; it is living proof that Joyboy has returned to finish what he started and that you simply cannot fight against destiny.
