Goemon Ishikawa XIII  

, 石川 五ェ門

The thirteenth generation of renegade samurai, starting from the renowned figure Ishikawa Goemon (石川 五右衛門). This character has a sword known as Zantetsuken (斬鉄剣), meaning "iron-cutting sword", which is capable of slicing through almost anything. In one episode of the TV series, Goemon confessed that his sword cannot cut konnyaku (a starch-based jelly made from yams) because the blade simply gets stuck in it. Typically, Zantetsuken is used to slice inanimate objects, which Goemon considers unworthy of his blade and often says his catchphrase "once again, I have cut a worthless object" after doing so. Objects cut by Zantetsuken will disintegrate a few seconds later when Goemon sweeps through them with his sword. Although he is usually quiet, Goemon participates in Lupin's exploits less frequently than Jigen. Additionally, he is an accomplished pilot.
