Iwanbō is the name of a series of intricate battle puppets created and piloted by Gein. Iwanbō version 1 was a member of the Juppongatana.


Iwanbō’s only weapons are thin, sharp blades attached to the tips of his fingers on both hands. Also, his thick skin is hard to perforate, has shown in battle at the Aoi-ya, where the Kyoto Oniwabanshū engage him with several shurikens, only to see they had no effect.



Iwanbō version 3

Iwanbo is silent with the occasional laugh. In the disbanding of the Juppongatana, he is shown laughing atop an unknown plateau. In the Jinchuu Arc, Iwanbo is shown to actually be an advanced mechanical puppet created by Gein for combat purposes. Gein also constructed Iwanbo version 3, which had a much different appearance and was much stronger than the first puppet.
