Kings in One Piece
All that I can do is human in nature...

In the series, there are several kings introduced, portrayed in various manners.

A few fit the stereotypical description of tyrants driven by avarice and cruelty, such as the spoiled Wapol forcing his subjects to beg him for medical treatments while having no political skills, and the king of Goa ordered the burning of the Grey Terminal to clean up his kingdom's image. Such kings are viewed with scorn and disdain by their oppressed subjects, and can even be overthrown.

Others, however, are more benevolent rulers, bearing good intentions for their kingdom, and are willing to sacrifice themselves if necessary. Such examples include Nefertari Cobra and Neptune, both of whom were well beloved by their country. Even Donquixote Doflamingo, the king of Dressrosa, remains highly popular within the island he rules.

Despite a king is guarded by their Royal Guards, some kings portrayed within the series are powerful fighters (and even Devil Fruit users) themselves, such as Wapol, Doflamingo, and Elizabello II. Neptune was once a soldier himself, and his sons are also trained in combat and are considered to be their respective kingdom's greatest fighters.
