TL;DR: The "D." in names like Monkey D. Luffy, Gol D. Roger, and Trafalgar D. Water Law is a secret initial tied to an ancient clan that opposed the World Government's founding. The World Government calls them "the natural enemies of God" — but what that actually means remains one of One Piece's biggest unanswered questions.
What is the Will of D.?
The Will of D. refers to a shared characteristic — spiritual, ideological, or possibly bloodline-based — among those who carry the middle initial "D." in their name. The initial appears across different races, nationalities, and centuries, with no clear common ancestry, suggesting it represents an affiliation or heritage rather than a family name.
The World Government is aware of the D. and actively suppresses knowledge of it. Marines with the initial tend to hide it. The Five Elders and Gorosei regard D. bearers as a historical threat.
What the Canon Actually Says
Oda has confirmed very little explicitly. What is established:
- Whitebeard (chapter 576): "The D. will cause another storm." Said moments before his death.
- Donquixote Rosinante (chapter 764): Explains to Law that D. bearers have historically been called "the natural enemies of God" and that they smile before death.
- Gol D. Roger smiled at his execution. Portgas D. Ace smiled dying. Rosinante himself laughed as he was shot.
- The Gorosei acknowledge the D. exists and find it threatening.
- Trafalgar Law's full name — Trafalgar D. Water Law — is treated as significant but unexplained.
No chapter has yet defined the D.'s origin or purpose in full.

The Leading Theory
The most widely supported theory is that the D. clan are descendants of the ancient kingdom that the World Government (formed by the 20 Allied Kingdoms) destroyed 800 years ago during the Void Century. The Poneglyphs were created by the people of Wano to record the true history that the World Government erased.
Under this theory:
- The ancient kingdom represented freedom and stood in opposition to the World Government's founding ideology of control
- The D. is a mark of lineage or allegiance to that kingdom
- "Enemies of God" refers to the Celestial Dragons and Gorosei, who consider themselves descendants of divinity
- The Will of D. is the continuation of the ancient kingdom's mission — to eventually dismantle the World Government's false world order
Evidence For
- The D. appears across centuries with no shared nationality, consistent with a scattered diaspora after a kingdom's destruction
- Garp and Roger — opposite sides of the law — both carry D. and both threatened the existing order despite serving it
- Nika/Joyboy connections: Luffy's fruit being tied to a figure from 800 years ago aligns with the ancient kingdom timeline
- The Five Elders' fear of Luffy specifically as a D. bearer goes beyond just his power
Evidence Against / Complications
- Blackbeard carries D. and is presented as villainous, suggesting D. does not equal "hero"
- Garp spent his life serving the Marines — if D. means opposition to the World Government, his role complicates it
- We have no confirmed D. bearer from the ancient kingdom itself yet
Why It Matters
The Will of D. is essentially One Piece's answer to the question: what is the series actually about? At its core, the conflict between the D. clan's legacy and the World Government represents the series' thematic battle between freedom and control, truth and suppression. Resolving the D. mystery is likely inseparable from resolving One Piece itself.
Still Unanswered
- What does D. actually stand for? (The most asked question — likely revealed near the series' end)
- Is the D. a bloodline, an ideology, or both?
- How does Blackbeard fit — does he represent a corruption of the D.'s purpose?
- What was the ancient kingdom called?
Frequently Asked Questions
Is the Will of D. confirmed canon? The D. initial and the fear it causes among the World Government are fully confirmed. The explanation of what it means is still unrevealed as of the latest chapters.
Does everyone with D. have special powers? No confirmed link between the D. and any ability. The shared trait appears to be temperament (smiling at death) and historical significance, not a power.
When was the D. first mentioned? Whitebeard's pre-death speech in chapter 576 is the first explicit discussion of D.'s significance. The initial itself appears from chapter 1.
