If the character is supposed to be 'Iconic'............
then how many choices do we have?
Garth sort of is, but they would never take a character from so shoddy/campy an episode
He can't be Klingon unlless he's been altered--that's lame
Another Romulan -- also lame
Vulcan--it is possible if they left off the ears for the outdoor shooting that got caught on film. Add the ears later for those shots using CGI?
Who else is Iconic?
TOS wasn't like a comic book with one villain after another and many to choose from.
