Eureka (2006)

The show primarily focuses on scientific anomalies and their resolution, rather than direct physical combat. While female characters like Jo Lupo are portrayed as capable and assertive, there are no clear instances where they decisively defeat one or more male opponents in close-quarters physical combat.

Eureka is an original science fiction series with no prior source material, historical figures, or legacy characters. All characters were created specifically for the show, therefore no gender swaps occurred.

Eureka is an original science fiction series, not an adaptation of pre-existing material or a historical account. All characters were created for the show, meaning there is no prior canon or historical baseline against which a race swap could occur.
