Hans Liengel, a scientist aligned with Nazi Germany, spearheads the development of cutting-edge military weapons fueled by stolen alien technology. His most significant creation, the Panzer Knight Bolwerkr, is a towering humanoid combat robot integrated with extraterrestrial components. Bolwerkr’s armored frame merges militarized engineering with Norse mythological motifs, featuring wing-shaped auditory sensors, a flowing cape-like appendage, and a swastika insignia fused into its chestplate. The machine’s power source exerts lethal crushing forces that prove fatal to its pilot, prioritizing destructive potential over pilot survival.

As a central antagonist, Liengel partners with Axis operatives to weaponize alien advancements in pursuit of worldwide supremacy, directly opposing the Kishin Corps. Bolwerkr’s deployment intensifies wartime conflicts, its unmatched combat prowess enabling it to overpower singular Kishin units. This project epitomizes Liengel’s unrelenting commitment to militaristic innovation and his readiness to exploit otherworldly technology without moral consideration.
