Metphies, an Exif priest surviving Godzilla’s conquest of Earth, outwardly provides spiritual solace to humanity while covertly orchestrating their downfall. His true mission—honed by his species’ worship of King Ghidorah, a planet-consuming interdimensional entity—is to manipulate civilizations into summoning their deity, believing this cyclical annihilation liberates life from inherent meaninglessness. He targets Haruo Sakaki, a vengeance-driven human, cultivating a years-long bond to mold him into Ghidorah’s unwitting herald. Exploiting Haruo’s hatred for Godzilla, Metphies positions him as a leader whose choices will trigger Ghidorah’s arrival, all while dismantling trust in rival factions like the Bilusaludo.

As the conflict escalates, Metphies converts survivors into Ghidorah cultists, employs telepathy to torment dissenters, and replaces his right eye with a Garbetrium bead to anchor Ghidorah in reality. Through psychological illusions, he reveals his orchestration of Haruo’s tragedies, including the destruction of a human vessel that cemented Haruo’s vengeful path. When resisted, Metphies weaponizes visions of Haruo’s lost loved ones, framing Ghidorah as the culmination of his suffering.

Haruo’s destruction of the Garbetrium bead severs Ghidorah’s tether, killing Metphies, who dies asserting Ghidorah’s inevitability. Haruo’s grief over his corpse underscores their fraught connection. Posthumously, Metphies lingers as a hallucination, warning that humanity’s relentless ambition risks reviving destruction cycles—a warning driving Haruo to self-sacrifice, ensuring Ghidorah’s banishment.

Calm, calculating, and zealously devout, Metphies’ nihilism stems from witnessing Godzilla-like entities erase civilizations. Yet subtle contradictions—allowing Haruo to defeat him unresisted, genuine curiosity about human resilience—suggest depths beyond fanaticism, framing him as both architect and enigmatic participant in Haruo’s tragic destiny.
