Devil Fruits and Haki are not the only paths to power. The world’s governments and labs have spent centuries building their own.
Rokushiki — the six powers
A set of superhuman martial techniques mastered by Government assassin agencies: walking on air (Geppo), moving faster than the eye (Soru), iron-hard bodies (Tekkai), and more. Rokushiki proves the human body alone can approach the supernatural — with enough training to break most people.
The lineage factor — Germa 66
Science can rewrite blood itself. Germa 66’s kingdom bred its royal children in engineered lineages — exoskeletons, superhuman strength, emotionless obedience by design. The series treats it as one of its sharpest tragedies: children manufactured as weapons. Scientific power also surfaces in clones and mass-produced soldiers, raising the story’s quietest ethical questions.
Vegapunk — the world’s greatest mind
The Government’s head scientist is centuries ahead of the field: the mind behind artificial Devil Fruits, laser weaponry, satellite-splitting research divisions (“the Punk Records”), and discoveries about the world that border on the forbidden. Where the Void Century is history’s secret, Vegapunk is science’s — and the final saga made his laboratory a battlefield for exactly that reason.
SMILE & artificial power
Industrialized power has a human cost: the mass-produced SMILE fruits built an army at the price of stripping their failed users of all expression but laughter. Artificial Devil Fruit research continues to this day — proof that the world’s powerful will pay anything for what the sea grants naturally.
The pattern to remember: every power system in One Piece — fruits, Haki, science — is the same question asked three ways. What will a person pay to stand above the sea? The story’s answer, over and over, is the crew that paid in everything but their dreams.
