Female characters occupy supporting roles that do not disrupt traditional power dynamics. The central conflict is driven by masculine archetypes like the grieving father and militaristic antagonist.

Metro City implies demographic plurality, but the film lacks intentional casting or arcs exploring ethnic identity. The protagonist's robot nature serves as an existential metaphor for otherness.
