The Rook Jyamato are stronger forms of Jyamato and major antagonists in Kamen Rider Geats. They lead groups of Pawn Jyamato and serve as mid-bosses in some rounds of the Desire Grand Prix.
History[]
A Rook Jyamato led a group of Thief Jyamato to battle the seven DGP Kamen Riders. Tycoon and Ginpen teamed up to fight it, but Rook Jyamato overpowered both of them and killed Ginpen, leaving Tycoon on his own. However, Geats then intervened and began fighting the Rook Jyamato alongside Tycoon. After convincing Tycoon to give him his Magnum Buckle, Geats defeated Rook Jyamato in his Boost Magnum form. With the Rook Jyamato's destruction, Geats was able to clench victory in the first round of the DGP.
After Archimedel fed Takeshi Gotouji's body to his Jyamato saplings, a Rook Jyamato was one of the Jyamato who gained the power to assume his form and repeat lines he had said.
