In this stylized depiction of the year 2000, Earth is characterized by a unified geopolitical front established to combat the recurring threat of giant monsters. This world is policed by the Earth Defense Force (EDF), a global military organization that utilizes high-tech warships and specialized mutant soldiers known as the M-Organization. The societal structure is defined by a state of constant readiness for environmental and kaiju-related disasters, leading to a highly militarized and technologically advanced version of the turn of the millennium.

The technological landscape focuses on biological and mechanical fusion. The presence of mutants with enhanced physical capabilities suggests a mastery of genetic engineering and human augmentation. Earth serves as a unified political center under threat, eventually falling victim to a sophisticated alien infiltration by the Xiliens, who exploit human desire for peace and technological advancement. This version of Earth diverges from reality through its accelerated military aerospace capabilities, exemplified by the flying battleship Gotengo, and its ability to harbor hidden underwater and ice-locked facilities.

The film’s predictions lean toward high-tech surveillance and globalized defense networks, paralleling the real-world growth of international security cooperation post-2000, albeit in a more fantastical form. While genetic enhancement remains a nascent field in reality, the film's depiction of a unified global response to extinction-level events mirrors modern climate and security dialogues. However, the reliance on manned super-vehicles has largely been superseded in the real world by drone technology and satellite-based intelligence, marking a significant divergence in how future combat was envisioned in 2004.
