Emperor Dokuma commands the technologically advanced Madokter Army, also known as the Madokuta organization, as the primary antagonist. His forces relentlessly assault Victor City, employing sophisticated weaponry and strategic operations to breach its defenses and seize its hidden scientific resources, positioning Dokuma as the central opposing force against the city's protectors. Driven by the desire to acquire Victor City's advanced technology, developed by scientist Kyōtarō Ōtaki, Dokuma directs his campaigns to claim this legacy for his own purposes. Specific episodes like "Puzzle of Dokuma 6000 year" and "Counterattack of Dokuma disk" explore aspects of his background or resources. Dokuma's antagonistic role culminates in decisive confrontations depicted in episodes such as "Decisive battle zone 9999" and "Super outer space of glory."
