Dr. Ratchet stands as the primary antagonist of the seventh One Piece film, ruling as feudal lord of Mecha Island. His thin frame, unevenly parted light brown hair, and narrow brown eyes cultivate a sinister presence. He dons yellow overalls exposing his chest, paired with a thick black scarf patterned with red gears. Functioning windshield wipers are integrated into the frames of his distinctive round, light orange glasses. A prodigious inventor, Ratchet engineered every mechanical system on Mecha Island, including its combat mechas. While possessing formidable intellect in mathematics, science, and analysis, he suffers from crippling deficits in wisdom and common sense. This imbalance fuels arrogance, delusions of grandeur, and a chronic habit of underestimating foes. He overthinks simple scenarios, exemplified when he initially failed to solve the island's central riddle without accidental aid from the Straw Hat Pirates. His personality blends pettiness, vindictiveness, and inept leadership, driven by ambitions of global conquest through his creations. His combat prowess relies on piloted Powered Suits activated by clockwork keys in their backs: - **Zogame-kun 5-go**: A turtle-shaped transport mech featuring a throne mounted on its shell. - **Tetsujin-kun 28-go**: A battle suit wielding cable-retractable drills and claws, plus magnetic feet for surface adhesion. - **Tetsujin-kun 32-go**: An incomplete amphibious mech armed with drills and cannons, hampered by slow-moving legs. - **Super Zogame-kun**: His ultimate, externally powered turtle-based machine, boasting cannons, six legs, and projectile arms with drills and claws. Childhood trauma from his father's death ignited Ratchet's obsession with machinery. As Mecha Island's ruler, he orchestrated a scheme involving the ancient giant turtle supporting the island. He manipulated the Straw Hat Pirates into solving the "Golden Crown" riddle, awakening the millennial turtle. Ratchet then seized control using mechanical cables, intending to weaponize it for world domination. His confrontation with Monkey D. Luffy resulted in the destruction of his mechas. The incomplete Super Zogame-kun was obliterated when Luffy unintentionally activated Gear 2 techniques. Defeated, Ratchet faced maternal punishment—a comedic spanking—for his plot. The legendary "Golden Crown" treasure was revealed as the golden shells of the turtle's newly laid eggs, which the Straw Hats ultimately failed to secure. His name derives from the mechanical ratchet tool. Beyond the film, he made a non-canonical appearance at the Pirates Festival in *One Piece: Stampede*. In series popularity polls, he placed 59th in the third poll and 122nd in the fourth.
