Kinjishi the "Flying Pirate" (空飛ぶ海賊 金獅子) is a notorious pirate. His name, Kinjishi, means "golden lion".

20 years ago, Kinjishi was the first prisoner to escape from Impel Down, due to a mistake made by the Marines.

Also worthy of note is that in the preview of the 10th One Piece movie scheduled to be released in December 2009, mention is made several times of a character in the movie bearing the exact same name, as well as supposedly being missing for twenty years, the approximate time of the Impel Down's escape.

Recently a new trailer for the movie has revealed him fully and as the major antagonist of the film. He appears to have swords for prosthetic legs and can send slashes from them in a Rankyaku like fashion.
