What if the D Clan isn’t just a random bloodline, but Joyboy’s chosen heirs?
The theory goes that Joyboy gave his “Will” to his crew, and the “D” was the mark of carrying on his spirit. Each bearer of the D isn’t just a descendant—they’re a potential vessel for Joyboy’s return. That’s why Imu and the Celestial Dragons fear the D clan so much: they believe Joyboy will reincarnate through them and restart the war the Ancient Kingdom lost.
This also explains why they’ve been exterminating the Buccaneers and why characters like Blackbeard, Law, and Luffy carry such weight in the story. Imu isn’t just trying to control the world—they’re trying to stop Joyboy’s rebirth.
If true, it would mean Luffy is not just Joyboy’s successor but his actual second coming. That makes the Final War not just pirates vs. Marines, but Joyboy vs. the World once again.
Or maybe… it’s all just a coincidence. 👀
