Mirror Universe Cast
The Mirror Universe, for many writers and fans, is a big, campy laugh. But I don't see it that way.
Instead, for me, it's totalitarianism. During Empress Hoshi's time (from 2155 in canon, to 2245, in my fanon) in particular, it is, to me, tarted-up totalitarianism, a kind of Brave New World in garters.
And the Empress Hoshi Sato is the biggest tart of them all.
Original Characters and Actors
All actor and actress selections are intended to give the reader a bit of a pictorial framework, nothing more. If you imagine someone else, then have at it! These are original characters and so the sky is essentially the limit.
Lead Original Characters
Leonora (Norri) Digiorno (Alyson Hannigan) - this character suffers a particularly senseless death in the MU; Doug Beckett (Steven Culp); Pamela Hudson (Kaley Cuoco) - in the Prime Universe, Pamela is a doctor. In the MU, she has a science background, but supplements it with other work. In Temper, she's little more than a prostitute. In the HG Wells series, she is shown briefly as a pinup girl; Melissa Madden ( Catherine Bell) - this character has a tragic death in the MU; and Charlotte Lilienne (Lili) O'Day (Naomi Watts). In the Mirror, she does not survive past age nine.
