Okama is a Japanese slang term for transvestite or homosexual. The first okama to appear in the story is Bentham, also known as "Mr. 2 Bon Kurei", who first appeared as an enemy to the Straw Hat Pirates, but ended up being friends with them. The Kamabakka Kingdom is the Okama kingdom, (which Sanji was sent to) and even the animals on the island are shown to be okama. The ruler of the Kamabakka Kingdom is Emporio Ivankov. In the FUNimation subs they are known as Queers.
