The sole progressive element is the original supporting character Zero, explicitly portrayed as genderfluid, using she/they pronouns, and self-identifying with activist labels including anticapitalist and post-colonial feminist. Episode 4 features a dedicated pronouns-clarification scene that creates group conflict and humor, normalizing the identity within the ensemble and tying it to generational themes. Research confirms this is an original character with no source-material predecessor, rendering any casting-comparison claim unresolved and eliminating any established-character change floor.
