Did you spot the trans character in the second episode of the Christopher Eccleston series?

It's the one set on a space station in the far future where the representatives of various races have gathered to watch the sun engulf the earth. The villainess, who I think was called Cassandra - I may be wrong about that - was a thin sheet of human skin with a female face that needed continual moistening from her lackeys. At one point she clearly states that she grew up as a boy.
