Gihren Zabi, eldest son of Degwin Sodo Zabi, rose as an instrumental force within the Principality of Zeon’s political and military hierarchy. From his early years, he displayed sharp political instincts, engaging in anti-Federation operations and aiding his father in securing authority over the Autonomous Republic of Munzo. Leading the Zeon Party’s political department, he shaped public sentiment through calculated propaganda, casting the Earth Federation as tyrannical oppressors to fuel Spacenoid nationalism. His strategic brilliance, paired with a 240 IQ, allowed him to reframe Zeonism into a doctrine proclaiming Spacenoid evolutionary supremacy, casting Side 3 as the nucleus of humanity’s future. During the One Year War, Gihren’s decisions proved decisive. He masterminded Operation British, deploying nerve gas to purge Side 2’s population before attempting to crash the colony onto Jaburo—a plan that missed its target and obliterated Sydney. These colony drops, alongside superweapons like the Solar Ray, exemplified his ruthless pragmatism. The Solar Ray’s activation during peace talks eradicated both General Revil and his own father, Degwin, laying bare his readiness to discard kinship for ideological triumph. His rule blended charismatic oratory with iron-fisted authoritarianism, echoing historical despots through militaristic rallies, pervasive propaganda, and the infamous "Sieg Zeon" salute. Though he espoused Spacenoid liberation, his true aim centered on total hegemony over the Earth Sphere, even advocating the culling of Earth’s populace to 50 million to "restore" the planet. Factional strife within the Zabi family shaped his downfall. Tensions with his sister Kycilia culminated in her assassinating him for patricide, exposing the internal divisions eroding Zeon’s war machine. His overreliance on prototype weapons like the Big Zam mirrored strategic hubris, hastening Zeon’s collapse at A Baoa Qu. Gihren’s ideology outlived him, permeating remnants such as the Delaz Fleet and inspiring groups like the Titans, who mirrored his rhetoric of elitist dominion. Expanded media like *The Plot to Assassinate Gihren* detailed his orchestration of political schemes, leveraging agents such as Cecilia Irene to purge adversaries. His legacy endures as a grim parable of ambition fused with ethical decay, perpetuating the Universal Century’s endless cycles of war.
