I know that Bentham sacrificed himself to save Luffy so that he can escape from Impel Down. He disguised as Magellan to open the gates for Luffy, but later the real Magellan came and it seems like the two fight each other (not in screen).
My friends believed that he's dead at that fight. But when I read this, it is stated that he's currently become the new queen of Newkama Land.
Bentham, alias Mr. 2 Bon Kurei, is a former officer agent of Baroque Works and an okama (a Japanese slang term for a transvestite). 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.
So I want to know, is Bentham or Bon Kurei dead or alive after Impel Down arc? If he alive, have he shown in comics ar anime after Impel Down arc?
