The television series "Snowpiercer" does not feature any identifiable transsexual characters or explicitly explore themes related to transsexual identity within its narrative. The show's primary focus is on class struggle, survival, and political intrigue aboard a perpetually moving train.

The movie does not contain any action or adventure elements.

The show introduces Melanie Cavill, an original female character who initially impersonates the canonically male Wilford. However, Wilford himself (a male character) is later revealed and portrayed as male. No established character from the source material is directly gender-swapped.

The Snowpiercer series introduces new characters and a distinct storyline, rather than directly recasting established characters from the prior film or graphic novel with different races. Characters like Andre Layton are original to the show's continuity.
