For more than 25 years, One Piece has earned its reputation for layered storytelling and mysteries that unfold at a deliberate pace.
Throughout its run, Eiichiro Oda has introduced countless plot threads that remain unresolved, encouraging fans to theorize and speculate.
What began as casual community discussions has evolved into a massive theory-driven movement—especially after several early theories turned out to be true.

Holy Knight God Valley One Piece
Now that the manga has entered the Final Saga, Oda has started pulling back the curtain on some of the biggest unanswered questions.
The most notable revelation so far is the God Valley Incident, which has reshaped the way fans view the story.
However, a new theory has recently captured the spotlight: each Holy Knight may be directly—or thematically—linked to a specific member of the Straw Hat Pirates, potentially shaping their pasts in hidden ways that are only now coming to light.

Nami Elbaph One Piece
The alleged connection between Nami and Sommers is where this theory gains momentum. Sommers stands out as a remarkably informed Celestial Dragon, able to recognize Jaguar D. Saul’s identity long before most nobles could.
This detail raises speculation that Sommers might have ties to the tragedy of Nami’s childhood—rooted in genocide and Marine negligence.

Saint Sommers Shepherd Elbaph One Piece
Some fans believe Sommers may have overseen, planned, or been involved in those events, and may even share a connection to Nami before Bell-mère adopted her.
Not necessarily a biological relationship, but a political or narrative link that aligns with Oda’s pattern of tragic irony, systemic injustice, and emotional backstory twists.

Saint Killingham Elbaph One Piece
A parallel also exists between Jinbe and Killingham. Killingham’s ability to summon monstrous entities is seen as a symbolic reflection of how Fishmen have been historically treated—feared, dehumanized, and oppressed.
The theory suggests that Killingham may have influenced or weaponized this hatred, making him a driving force behind centuries of discrimination toward the Fishmen race.

If Jinbe ultimately confronts Killingham in the Final Saga, the moment could represent long-awaited poetic justice and a deeply personal clash.

Kuina and Zoro One Piece
Perhaps the most emotional component of the theory involves Kuina. Many fans have long believed her death was too ambiguous, especially given her heritage as a descendant of legendary Wano swordsmen, her ties to cursed blades, and the absence of her body.
Viewers have noticed a female Holy Knight who shares a striking resemblance to Kuina, raising speculation that Oda may be preparing a storyline in which she returns—but not as the girl Zoro remembers. If true, this would force Zoro into a devastating internal conflict, challenging everything he believed about his past.

Months ago, this speculation might have been ignored. But as Oda continues revealing more lore, patterns become increasingly difficult to overlook.

If the theory is true, the Final Saga will not simply be Luffy versus the World Government. It would be each Straw Hat confronting a grim, personal reflection of their own history—turning the climax of One Piece into something far more emotional, intimate, and explosive than ever imagined.
