Bentham

Bentham, alias Mr. 2 Bon Kurei, is a former officer agent of Baroque Works and an okama (a Japanese slang term for a cross dresser). While he was once an enemy of Luffy's as a part of the Baroque Works, the two became quick friends, leading Bon Kurei to sacrifice himself for Luffy both at Alabasta and later at Impel Down. He is currently the new Queen of Newkama Land.
