Steven Universe Future explores diverse gender identities and expressions, particularly through non-binary characters and an alien race that challenges traditional gender norms. However, the series does not feature characters explicitly identified as transsexual, focusing instead on broader themes of identity and self-acceptance.

While female-presenting characters, primarily Gems, engage in various forms of combat often utilizing their inherent superpowers, there are no instances in the series where a female character defeats one or more male opponents in direct physical combat. The show's narrative focuses on Steven's internal struggles and relationships, with few direct physical confrontations against male antagonists by female characters.

All established characters in Steven Universe Future maintain their canonical gender presentation and pronouns from the original Steven Universe series. No character originally established as one gender is portrayed as a different gender.

Steven Universe Future continues the story and characters from the original Steven Universe series. All established characters, whether human or alien Gems, maintain their consistent visual depictions and voice actors from prior installments. No character's race was altered.
