Joyboy's real name is never explicitly revealed in the One Piece manga or anime. The character is shrouded in mystery, mentioned only in passing throughout the story.
The only concrete information we have about Joyboy is:
- He was a powerful figure in the past, possibly a king or a warrior.
- He left a message for the future, likely related to the ancient weapon Pluton.
- He was involved with the ancient kingdom and the "Void Century," a period of history that was intentionally erased from the world.
While Joyboy's true name remains unknown, fans have speculated about who he might be. Some popular theories include:
- Gol D. Roger: The Pirate King, who may have been Joyboy's descendant or successor.
- Monkey D. Garp: The "Hero of the Marines," who possesses a strong connection to the past and might be related to Joyboy.
- Monkey D. Luffy: The main protagonist, who shares the same initials as Joyboy and possesses the characteristics of a "free spirit" that align with Joyboy's legacy.
Ultimately, only Oda Eiichiro, the creator of One Piece, knows Joyboy's true identity. The mystery surrounding this enigmatic figure adds to the intrigue and depth of the story.
