Okama Kenpo is the fighting style used by Bentham. It is a style that uses mainly kicks and is taken directly from ballet dancing, therefore most of its stances are ballet poses rather than martial art stances. In a response to a fan, in order to learn Okama Kenpo, a person must do three steps: first a person must learn ballet, secondly they must learn karate, and third, they work at one of "those" places. Because of the complexity of the moves, Bentham can only use it with his own body which makes his Devil Fruit a liability. It is called Ballet Kenpo (バレエ拳法 Barē Kenpō?, literally meaning "Ballet Fist Way") in the Alabasta Arc in the anime.
