Goemon Ishikawa XIII

The thirteenth generation of renegade samurai, beginning with the legendary figure Ishikawa Goemon (石川 五右衛門). He has a sword called Zantetsuken (斬鉄剣), meaning "iron-cutting sword", which can cut through almost anything. In one episode during the TV series Goemon admitted that his sword cannot cut konnyaku, which is a starch-based jelly made from yams, because the blade just gets stuck in it. The Zantetsuken is usually used to cut inanimate objects, which Goemon considers unworthy of his blade and often mutters his catchphrase "once again, I have cut a worthless object" after doing so. Objects cut by Zantetsuken will fall apart a couple of seconds after he sweeps through them with his blade. He is usually quiet and participates in Lupin's exploits less frequently than Jigen.

He is also a skilled pilot.
