Scientists in One Piece

In the series, Scientists often serve the goals of a higher authority. Some have command over their own stations and have a team who assist them. Some have been able to manipulate and transform the environment, and even achieve space travel. Depending on the person, their creations can either be used for good or for evil; but they are usually utilized to create weapons and tools for their comrades or themselves.

Cyborgs are one of the most common yet advanced inventions of scientists, along with giving Devil Fruit abilities to inanimate objects such as swords. Gigantification is one of the most sought after goals for scientists, and many have worked on it for centuries, but due to the complexity, the perfected version has yet to be accomplished; success would bring worldwide fame and glory to the scientist who achieves it.[1]

Despite most scientists being figures of renown and respect in the world, a few are known to skirt the law in order to conduct research deemed less ethical, which was, for example, the purpose of groups like MADS or Caesar Clown's secret organization backed by Donquixote Doflamingo. Certain subjects and practices are outlawed by the World Government, and dabbling in said topics may result in the arrest of the responsible scientist. The procedure for cloning humans is one such example.[2]

Willie Gallon

Willie Gallon (ウィリー゠ガロン Wirī Garon?, VIZ Media: Willy Karen) is a physicist.[3] Little is known about Willie Gallon. It is known that he believes that everything that can be imagined can become reality.
