Marshall Hitler holds the position of military leader within the Hyakki Empire, also called the Hundred Demons Empire, serving as the central antagonistic force in the Getter Robo G narrative. His appearance features a distinct small mustache and jackboots, recalling the visage of a historical 20th-century German leader. As a high-ranking general, he engages in strategic planning and directs the empire’s forces against the Getter Team. The Hyakki Empire pursues Earth’s conquest and humanity’s eradication through advanced technology and militaristic methods. Leadership dynamics within the empire are marked by internal conflict, as Marshall Hitler consistently clashes with a fellow general. This rivalry fractures their coordination, frequently resulting in fragmented assaults against the protagonists instead of unified large-scale offensives. His tactical approach centers on deploying individual mechanized units in episodic confrontations against Getter Robo G. Despite escalating threats later in the conflict—including attempts to mobilize multiple units simultaneously—these efforts ultimately fail to overcome the Getter Team’s resistance.
