B'T Raidoh is a mechanical life form classified as a B't, designed in the form of the Azure Dragon from Chinese mythology and manufactured by the Machine Empire. He serves as the dedicated partner of the Spirit General Ron, operating under Ron's absolute commands with a predominantly stoic and obedient disposition.

Raidoh excels at exceptional speed and agility, achieving movement comparable to lightning during combat. His offensive capabilities include generating thunder-based energy blasts, utilizing his dragon-inspired mechanical physiology for tactical advantage.

Raidoh's journey mirrors Ron's evolving allegiance. Initially, both display unwavering loyalty to the Machine Empire, serving as elite enforcers without question. However, exposure to the protagonists' ideals and witnessing the Empire's morally corrupt objectives sparks their disillusionment. Raidoh accompanies Ron in questioning the Empire's leadership, particularly concerning the destructive potential of the ultimate B't, Raphael, and the Machine Emperor's true motives. This culminates in their pivotal decision to defect and join the rebellion against the Empire during its final confrontation.

The bond between Raidoh and Ron embodies the series' theme of partnership. Their synergy as donor and B't evolves from hierarchical command into a relationship of mutual reliance, underscoring the narrative's emphasis on unity and trust against adversity.
