Also known as: ヨロイ元帥
He is the last of the evil commanders to appear in Kamen Rider V3 (Series), and also the leader of the "Yoroi Ichizoku" (Armor Clan), a tribe that allied itself with Destron.
He is clad head to toe in Red Armor reminiscent of a Crustacean, and wields a Spiked Ball And Chain mounted on his left hand.
Cruel and self-serving, he attempted to kill Yuuki Jouji because Jouji’s rise within the Destron organization had become a hindrance to him (Jouji lost his left arm but managed to escape).
<spoiler>His true form is Zariganna, a Crayfish-like cyborg.</spoiler>
