One piece

The world of One Piece is populated by humans and other races such as dwarves (more akin to faeries in size), giants, merfolk, fish-men, long-limbed tribes, long-necked people known as the Snakeneck Tribe, and animal people (known as "Minks"). The world is governed by an intercontinental organization known as the World Government, consisting of dozens of member countries. The Navy is the sea military branch of the World Government that protects the known seas from pirates and other criminals. There is also Cipher Pol which is a group of agencies within the World Government that are their secret police. While pirates are major opponents against the Government, the ones who really challenge their rule are the Revolutionary Army who seeks to overthrow them. The central tension of the series pits the World Government and their forces against pirates. The series regularly emphasizes moral ambiguity over the label "pirate", which includes cruel villains, but also any individuals that do not submit to the World Government's authoritarian—and often morally ambiguous—rule. The One Piece world also has supernormal characteristics like Devil which are mysterious fruits that grant whoever eats them transformative powers.
