The Witcher: Blood Origin does not feature any identifiable transsexual characters or themes within its narrative. The series focuses on a fantasy prequel story set in the elven kingdoms, prior to the main Witcher saga, without engaging with this specific aspect of identity.

The Witcher: Blood Origin introduces an entirely new cast of characters created specifically for this prequel story. As these characters do not have established canonical genders from prior source material, there are no instances of gender swapping.

The series primarily features new characters whose races were not established in prior Witcher canon. Existing characters are portrayed consistently with their source material depictions, thus no race swaps occur.
