Senator Tal’aura: In Star Trek: Nemesis the murderous Senator Tal’aura (Shannon Cochran) was a member of the Romulan Senate who secretly allied herself with Shinzon of Remus. She used a thalaron radiation projector to assassinate the entire Senate thereby setting the movie’s events in motion. Shannon Cochran had played a number of other guest roles in various Star Trek series including the Klingon Lady Sirella. Nemesis also featured Dina Meyer as the Romulan Comander Donatra. Michael Westmore was makeup designer and supervisor.
Karina: In the Deep Space Nine episode ‘Visionary’ Karina (Annette Helde) was a diplomat for the Romulan Star Empire who visited Deep Space 9 to be briefed on Starfleet intelligence on the Dominion: she was unimpressed.
‘Romulan’ officer: Picard, Geordi, Troi and Data return from a Federation conference to find the Enterprise and an attacking Romulan Warbird frozen in time. But things are not quite as they seem: aliens from a different time-continuum have assumed Romulan bodies, including a female (Patricia Tallman), in order to survive in this continuum.
