Was Joy Boy a person, a title, a god, or a will? How does Luffy fit?

The question

Who was Joy Boy, the Void-Century figure who left the apology on the Fish-Man Island poneglyph?

Leading theories

Joy Boy ≠ Nika; Joy Boy is the original Nika fruit user

Broadly accepted post-Vegapunk. Luffy is the next Joy Boy because he ate the same fruit + carries the will.

Luffy is the literal reincarnation/inheritor

Fulfilling a promise Joy Boy made to Fishman Island and others.

Joy Boy’s “promise” was to break the Red Line / restore the One Sea

Connects to Vegapunk’s sinking world. Luffy must finish what Joy Boy couldn’t: drain the world or raise the lost lands.

Joy Boy was a Buccaneer

Kuma’s race — explaining the persecution of Buccaneers and Kuma’s near-Joy-Boy status. Kuma defied fate to save the modern Joy Boy (Ch. 1164 Kuma reveal).

Resolution

Partially resolved — Joy Boy is confirmed as a real Void-Century person tied to the Sun God Nika, and Luffy is repeatedly named as his successor, though the exact nature of that inheritance stays sealed.

  • Joy Boy was an individual living person of the Void Century — the author of the Fish-Man Island apology poneglyph, who made and broke a promise to the island; the royal legend holds that someone will one day fulfill it in his stead (Ch. 649, Ch. 967).
  • Vegapunk’s broadcast fixes him in history: born some 900 years ago into the advanced ancient kingdom, the first man ever called a pirate, who fought “like the Sun God Nika” with a body that stretched and contracted (Ch. 1114, Ch. 1115).
  • Luffy is named as Joy Boy the instant his awakened fruit — revealed as the Hito Hito no Mi, Model Nika — restarts his heart, first by Momonosuke through Zunisha (Ch. 1043, Ch. 1044).
  • Ancient witnesses independently attach the name to Luffy: Zunisha remembers Joy Boy’s rhythm and calls itself his companion (Ch. 1040, Ch. 1046), and the reawakened Iron Giant Emet addresses Luffy directly as “Joyboy” (Ch. 1119, Ch. 1120).
  • Imu carries a personal, centuries-old stake in Joy Boy, reacting viscerally to the name (Ch. 1122) and, in the latest chapters, confronting Gear-5 Luffy face to face as “Joyboy” (Ch. 1187).

Still open: Whether Luffy is Joy Boy’s literal reincarnation, the inheritor of his fruit and will, or something else — the deeper Joy-Boy/Nika identity is not spelled out. In the newest, still-unconfirmed chapters Imu even recants the identification, declaring Luffy “not Joy Boy” (Ch. 1188).

Still open: The exact content of the “promise” Joy Boy left to Fish-Man Island and the Sea Kings (Ch. 647, Ch. 649).
