Zoa commands the Evoluders, a biomechanical warrior race born from a human expedition to the Cygnus constellation two centuries ago. Time dilation during their voyage catalyzed their evolution into mechanized beings, forging a culture centered on conquest and survival. As the military’s iron-fisted strategist, Zoa ruthlessly enforces this creed, personally executing devastating campaigns to expand their dominion.

Though outwardly loyal to Lady Mhiku, the Evoluders’ sovereign, Zoa covertly exploits her authority to advance his genocidal ambitions. His nihilistic worldview—rooted in Earth’s perceived abandonment of their mission—convinces him that universal power alone ensures survival. This drives his relentless assault on humanity, culminating in the activation of Combat Planet Zohma’s anti-matter cannon to annihilate Earth.

In his climactic duel with Orgun, Zoa mocks his rival’s empathy for humanity, framing it as vulnerability. Their clash peaks as Zoa triggers the cannon, only for Orgun to harness solar energy via his Grand Cross technique. Despite Zoa’s tactical dominance, his dismissal of human resilience proves fatal. Mortally wounded, he begrudgingly concedes the potency of emotion and spirit—ideals he once scorned.

Zoa’s biomechanical frame integrates Ovarium 808, a nigh-indestructible alloy enabling endurance in lethal environments. Combat prowess includes chest-mounted energy projectiles, retractable wrist blades, and strategic mastery over Evoluder legions. As both enforcer and architect of planetary invasions, he embodies the regime’s merciless ethos.

His demise during Zohma’s destruction marks the collapse of his power-obsessed dogma. This defeat fractures the Evoluders’ warmongering hierarchy, permitting Lady Mhiku to redirect her people toward evolution through unity rather than destruction.
