Halu-elu Dolu-do serves as a Bilusaludo lieutenant general aboard the United Earth emigrant spaceship Aratrum. As chieftain of the Bilusaludo, he wields significant influence on the ship's Central Committee. After Godzilla Earth annihilates nearly all human landing forces, Dolu-do urgently advocates for immediate withdrawal from Earth orbit. He dismisses the possibility of survivors, stressing the threat Godzilla's atomic breath poses to the Aratrum itself, citing simulations confirming its ability to penetrate the atmosphere and strike the vessel. Confronted with concerns about abandoning potential survivors, he counters that all forces are already destroyed and insists retreating to the Moon's orbit is a necessary precaution. This position results in a compromise: a limited 48-hour drone search precedes departure.

Dolu-do maintains a pragmatic, survival-focused perspective. He expresses skepticism regarding environmental conditions upon humanity's potential return, countering optimistic assumptions by noting the possibility of worsened circumstances. He also speculates about Godzilla potentially multiplying during the 20,000-year absence, reflecting an inquisitive yet realistic approach to threats. This practicality extends to his assessment of losses, including acknowledging the psychological impact from the destruction of a landing craft carrying elderly passengers during the initial exodus.

Following the failure of the Mechagodzilla City operation in "Godzilla: The Planet Eater," Dolu-do reviews transmission footage of Haruo Sakaki's confrontation with Mulu-elu Galu-gu. He immediately brands Haruo a traitor for sabotaging the operation. When Takeshi J. Hamamoto defends Haruo's actions, Dolu-do escalates the conflict, leading a Bilusaludo faction to seize control of the Aratrum's power station. He demands Admiral Unberto Mori formally condemn Haruo, cutting ship-wide power as leverage until his demand is met. During Ghidorah's attack on the Aratrum, Dolu-do contacts Mori and Hamamoto in confusion as gravity distortions tear through the ship. He reports his inability to restore power despite attempts, moments before the power core detonates, killing him and his Bilusaludo faction.
