Imperatore Ingues commands the Marduk Empire as its unyielding sovereign, a humanoid alien monarch driven to impose cultural purity across the cosmos by eradicating foreign influences through merciless conquest. His rule is fueled by fanatical devotion to Marduk supremacy, perceiving even subtle external traditions as existential threats. To enforce this vision, he deploys vast armies of enslaved Zentradi and Meltlandi warriors, their battle frenzy amplified by Emulators—Marduk vocalists whose hypnotic songs weaponize their aggression.

Ingues ruthlessly enforces conformity to ancient Marduk doctrines, mandating the annihilation of entire units contaminated by outside ideologies. This extends to his own forces, as demonstrated when he obliterates a flagship and its crew after Emulator Ishtar subverts his command by broadcasting Earth’s pacifist melodies. Such acts underscore his willingness to sacrifice strategic assets to preserve dogma, valuing ideological purity above military pragmatism.

In his campaign against Earth, Ingues overwhelms adversaries with ceaseless assaults, leveraging superior numbers and technology to crush resistance. His strategy hinges on cultural erasure and brute force, starkly opposing the protagonists’ use of music to foster unity and empathy. This rigidity becomes his undoing: by dismissing adaptability, he allows Ishtar’s covert defiance to corrode the loyalty of his soldiers, sowing discord within his ranks.

Ingues’s dominion fractures when Hibiki Kanzaki, Ishtar, and Silvie Gena unite to dismantle his regime. Their fusion of Earth’s culture with Marduk traditions sparks widespread rebellion among his forces, eroding his control. As defections mount and his commanders reject his extremism, the empire’s foundations crumble, culminating in the collapse of his tyrannical reign and the irreversible shattering of his absolutist ideals.
