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.
