B'T X

Teppei Takamiya’s reunion with his scientist brother Kotaro is shattered when the Machine Empire abducts him. Pursuing the kidnappers into their vast domain, Teppei is wounded and thrown into a scrapyard, where his blood unexpectedly awakens a discarded mechanical warrior: B’T X.

Unlike an ordinary machine, X has a will of his own and a bond to the person whose blood revived him. Together, the reluctant partners advance through the empire’s defenses, confronting powerful riders and their B’Ts as Teppei refuses to abandon his brother.
