The world of One Piece continues to evolve its power system in astonishing ways, from advanced Haki to Devil Fruit awakenings. However, the final saga demands Eiichiro Oda to raise the stakes even higher. The latest theory suggests that Luffy’s greatest power isn’t something entirely new, but an ancient ability linked to the Moon’s inhabitants: the Voice of All Things. This ability is the key to unlocking the origins of the mysterious “D.” clan and the truth behind the Sun God Nika.
Luffy Holds the Ancient Power of the Moon Tribe in One Piece
To understand the ultimate power Luffy is about to achieve, we must revisit the origins of the “D.” clan. The Harley prophecy introduced in the Elbaf arc offers crucial clues about the truth behind those who bear the mysterious “D” initial.
The Harley prophecy describes three worlds, mentioning the people of the full moon and the people of the crescent moon.
Fans know that in One Piece history, winged tribes like the Shandians, Skypieans, and Birkans descended from the Moon to the Blue Planet after their resources ran dry. The Shandians settled in the Blue Sea, Skypieans on the Sky Island, and Birkans in Birka.
Since interbreeding between races was common, the Moon people (the full moon tribe) had children with humans, creating the crescent moon tribe. The strongest theory is that these “crescent moon people” are the “D.” clan we know. This hybrid race carries blood from both the cosmos and Earth.
Hearing the Voice of All Things: The Power of the Crescent Moon Bloodline
Hearing the Voice of All Things is an ancient ability, awakened only in those carrying the “D.” bloodline. So far, those who have shown this power include Luffy, Roger, and others closely connected to the Ancient Kingdom like Oden, Momonosuke, and Shirahoshi (the Mermaid Princess).
Silvers Rayleigh once revealed about Roger: “Roger didn’t actually decode the Poneglyphs. He couldn’t read the ancient script. We’re pirates. We can’t match the intellect of Professor Clover or the Ohara scholars. He could hear the Voice of All Things in the world. That’s all.”
This supports the idea that hearing the Voice of All Things isn’t knowledge but a spiritual communication ability, likely inherited from the Moon ancestors. Luffy probably inherited this power from his grandfather Garp, even though Garp never displayed it. In fact, looking closely at the Skypiea arc, the physical resemblance between Luffy, Garp, and the Shandian elder is no coincidence.
Oda has clearly linked these characters, implying that Luffy carries the blood of the crescent moon people, meaning he has lunar origins. The Voice of All Things is the ultimate power Oda is preparing for the Final Saga.
The Sun God Nika May Also Originate from the Moon
Luffy’s connection to the Moon goes beyond the “D.” clan. The theory also suggests that the Sun God Nika was brought down to the Blue Planet from the Moon when the tribes descended.
The link between Luffy, the Moon, and the Sun God Nika is supported by scattered but systematic evidence throughout the story. First, both the Moon people and the crescent moon people pray toward the Sun, showing that this worship is part of the ancient heritage they carried when leaving the Moon.
Second, the Skypiean tribe, one of the oldest winged tribes, has long been known for worshipping the Sun God. Finally, and most notably, the Mink tribe’s Sulong power, the transformation into a pure white beast under the Moon, shares many visual similarities with Luffy’s awakened Gear 5 form. Clearly, this ancient energy originates from the Moon, and Luffy’s Gear 5 serves as the channel for this cosmic power.
