Dr., Ratchet

ドクター・ラチェット

Dr. Ratchet, the primary antagonist of the seventh film, is a brilliant inventor who believes his innate genius entitles him to rule the world. He serves as the Feudal Lord of Mecha Island.
He deceives the Straw Hat Crew into awakening the island (which is actually a giant turtle, with the island forming its shell), then uses massive cables to compel it to move wherever he wishes, furthering his plot for domination. Ratchet and his two henchmen pilot mechs to stop the Straw Hats, but fail. After his first mech is destroyed, Ratchet enters a gigantic mech in an attempt to defeat Luffy. At the last moment, Luffy (unknowingly) activates Gear Second and completely obliterates Ratchet's mech with a Jet Bazooka. As punishment for his misdeeds, he ends up being spanked by his mother.
