The film centers on heteronormative familial structures and the fraternal bond between Arthur and Orm. It lacks explicit non-cisnormative identities or visible queer-coded subtext within the central character arcs.

Mera serves as a powerful pillar of Atlantean stability, possessing significant political authority and combat proficiency. The narrative avoids submissive tropes, presenting a more egalitarian distribution of influence than classical mythologies.

The film moves away from Anglo-centric norms by featuring a diverse cast, including Halle Bailey and Amber Jody Watt. Atlantis is depicted as a multicultural, multi-ethnic civilization reflecting a globalized reality.

The story explores tensions between the surface world and Atlantis through environmental and industrial lenses. It touches on post-colonial themes regarding resource exploitation and the sovereignty of hidden civilizations.

The film lacks agency-driven portrayals of disability or neurodivergence. It only touches on physical vulnerability through the use of externalized power like the Black Trident to compensate for limitations.
