Antagonists

Antagonists are characters in the story of One Piece who oppose the protagonists—the Straw Hat Pirates—or their allies. Each story arc in the series typically features a main antagonist, and supporting antagonists of varying significance.

Overview
Antagonists in One Piece mainly come in two types: Enemy pirates and World Government forces, particularly the Marines. Because the protagonists are pirates themselves, they typically clash with other pirates, while the marines and other World Government organizations are naturally antagonistic towards them due to their criminal status. To date, the only canon arc to focus on antagonists wholly unaffiliated to any of the aforementioned groups is the Skypiea Arc.

Antagonist are usually defeated by the protagonists in the arc they appear in, but almost never killed. It is not uncommon for former antagonists to return in later arcs as allies of the Straw Pirates. By contrast, it is rare for a character to feature as a major antagonist again if they were already defeated in the past. Sometimes antagonists may feature in multiple arcs within the same saga, only being defeated for good in the last of arcs.

In order of descending importance, antagonists can be labelled as main, secondary, tertiary, major and minor. A main antagonist is the most significant enemy of the Straw Hat Pirates in a given arc. They are often the leader of an antagonist group and the most powerful or dangerous of the group. Typically the main antagonist is fought by the main protagonist Monkey D. Luffy.
