I confess that I was unaware of the existence of Panda man and for sure there are many more hidden treasures in manga and anime, mangakas usually leave them in sight but we never see them.
From the hearts on his chest I could think he belonged to the pirates at heart, in fact the picture you placed with Trafalgar Law may be a clue to that, but who knows, maybe there are a kind of many pandas all over the world.
This was very interesting, maybe now you are in charge of finding the treasures of One Piece 😅, there must be many more.
Hahaha! He's really everywhere. He's just not with Law in his pirate crew, he's also seen as Kaido's crew and many more. I've yet to find him in Kaido's crew though. 😂
I heard there's a movie that he's seen many times, not just once.
