Endurph serves as an Exif cardinal and lieutenant general aboard the Aratrum spaceship, bearing a weathered appearance accentuated by a prominent brow. Initially reserved, his demeanor shifts profoundly as events unfold.

In *GODZILLA: Planet of the Monsters*, he engages in debates over Earth’s recolonization, endorses Haruo Sakaki’s anti-Godzilla thesis, and argues for returning to Earth after the Tau-e colonization fails. He attends strategic briefings analyzing Godzilla’s weaknesses, observes troop deployments to Earth’s surface, and conducts pre-mission prayers with soldiers.

During *GODZILLA: City on the Edge of Battle*, he stays aboard the Aratrum following Godzilla Earth’s emergence. He proposes measuring Godzilla’s atomic breath range, deducing it threatens the ship in orbit. Advocating against immediate withdrawal, he pushes to search for survivors on Earth. After reconnaissance drones locate survivors, he witnesses Marco Ghione’s return and leads religious assemblies invoking a "promised day" and a deity’s return.

In *GODZILLA: The Planet Eater*, he silently exits a contentious committee meeting after listening to recordings of Mechagodzilla City’s destruction. Telepathically communicating with Metphies, he authorizes Ghidorah’s summoning despite operational risks. He directs followers in ritual chants to summon Ghidorah, standing transfixed as the entity manifests. Amid Ghidorah’s assault on the Aratrum, he emits maniacal laughter while engulfed in flames, culminating in his death.
