Theory Briefing
- Imu's memories in Chapter 1188 spoilers show Joy Boy's smile as nearly identical to Luffy's, the single detail fueling the time-travel theory.
- Luffy flatly rejects being called Joy Boy, insisting he is Monkey D. Luffy — suggesting Oda may be building a legacy story, not a time-loop one.
- Kozuki Toki's Time-Time Fruit already proved time manipulation exists in One Piece, giving the theory a foothold even though past travel has never been shown.
- A mysterious X mark on the robot Emeth mirrors the Straw Hats' secret Alabasta symbol, and Oda has offered no explanation — fans see it as a Luffy-Joy Boy link.
- Imu's taunt that Joy Boy would never be 'this weak' implies personal knowledge of the legend, framing Luffy as a successor still short of that standard.
