In the realm of shonen anime, main characters often exemplify law-abiding behavior to inspire positive change. However, One Piece takes a unique approach, portraying Luffy and his crew as outlaws challenging the World Government's ban on piracy. Amidst this dynamic, there are marines who, while upholding the law, harbor sinister motives they aim to fulfill through power and influence.

Within this intricate balance, certain individuals adhere to the World Government's regulations but are driven by a desire to do good, fitting the 'Lawful Good' archetype. These characters, though occasionally obstructing the Straw Hats due to their allegiance, are not inherently malevolent, despite occasionally assuming antagonist roles.
