He is the Left Minister and aide to the Darkness Army who serves Kuromajin. He commands the Darkness Army together with the Hishou and attacks Hoou Gundam and his allies, so at first it was thought that the two were the rulers of the Darkness Army. He has used his mobile fortress, the Big Zam, to conquer various areas, but struggles with Hoou and his allies after they obtain the Armor of the Three Bushous. When Shodai Gundam Daishogun is born, he finally offers help to Kuromajin, who rules over him. In addition to the Dragon Flame Cannon, he has a sword on his back called the "Ryusho no Kouken". He was once defeated by the Three Gundam Bushous, but is revived by the power of darkness and also gains the ability to transform into Ryuhi.
