The film contains no discernible LGBTQ+ characters or non-cisnormative identities. Social dynamics remain strictly traditional for the era and genre.

The Seatopian High Priestess subverts traditional hierarchies by holding absolute political and theocratic authority. While the human scientific ensemble is conventional, the central antagonistic power structure is defined by female agency.

Characters are predominantly Japanese, reflecting the film's production context. The Seatopian undersea race serves as a speculative sci-fi trope rather than a nuanced exploration of ethnic diversity.

The narrative explores the tension between surface society and the Seatopian civilization. While the High Priestess introduces theocratic elements, the film focuses on conflict rather than deep cultural critique.

There are no visible or invisible disabilities portrayed within the human or Seatopian casts. The story focuses on kaiju scale and technological capabilities.
