Kamagirigan: A mantis monster. He kidnaps and poses as Ismael, a friend of Oki Kazuya's and prince/ambassador of a foreign monarchy. The Dogma Kingdom would exploit this body switch, using the monarchy's finances to construct an underground command center filled with weapon provisions underneath its embassy. Incidentally however, Ismael is about to wed his childhood Japanese friend. He is given orders to ensure the marriage succeeds to keep up the pretense and further secure the Dogma's control over the Japanese government. He attempts to behead Kazuya and Choro after the wedding march is played but fails. He then takes the bride hostage before being defeated. Apart from mesmerizing people from the spirals in his eyes he wields two mantis scythe blades that can easily cut through wood. They are broken by Super-1's power hands and he is permanently weakened when his antennas are ripped off. Destroyed by Super-1's Super Rider Spark Kick.
He was later revived as part of the Dogma Revenge Corps and destroyed by Kamen Rider V3.He was yet again revived, this time to serve the Badan Empire, then destroyed by Kamen Rider Super-1's Hot/Cold Hands (Flamethrower).
