Lugal II, titled Lugal de Zahl, serves as the Denguil Empire’s foremost military commander and heir to Emperor Lugal’s tyrannical reign. His reputation for ruthlessness manifests in deliberate strikes against civilian transports and rescue vessels, reveling in the chaos inflicted on defenseless populations. This brutality mirrors his father’s doctrine of survival through strength, fueling his command during the invasion of Earth.

Tasked with executing Emperor Lugal’s campaign, he initiates assaults with hyper-radiation missiles, including a failed attempt to obliterate the Yamato. When the emperor unveils plans to submerge Earth using Aquarius, Lugal II directs the solar system invasion, systematically crushing evacuation efforts and military resistance. His tactical cunning surfaces as he evades Earth’s wave-motion artillery by warping his fleet to safety, then retaliates with precision.

The catastrophic defeat at Pluto, where the Yamato annihilates his armada, forces his retreat and ignites a vengeful obsession. Yet as the Denguil crumbles in their final clash, he abandons his fleet in a cowardly escape, only to perish colliding with the Uruk fortress’s neutrino shield.

Unaware his brother survives aboard the Yamato, he remains a pawn in his father’s disdain for kinship—a dynamic echoed when the emperor executes his younger son. Lugal II’s unrelenting allegiance to genocidal ambition cements him as a secondary antagonist, devoid of nuance or redemption. His arc concludes as a stark emblem of imperial cruelty, contrasting protagonists who champion empathy over conquest.
