Zigorou is the zombie number 850 of Thriller Bark. His body belongs to a legendary old stubborn that killed 7000 pirates to protect his family, but he has a shadow that makes him more powerful, the one from Roronoa Zoro. Thanks to this, Zigorou inherited many of Zoro qualities, including his sense for getting lost, and the ability to dominate the San-Tou-Ryuu. In general, due to his shadow, Zigorou has many problems with Inupen (who has Sanji's shadow) since Zoro doesn't get along with Sanji to well. However, if Inupen and Zigorou join for fighting, both are dangerous.
