Yvonne Craig - Then
Yvonne Craig's one-episode stint on the original Star Trek series made a lasting impression. In this episode, she portrayed Marta, an Orion slave girl whom Garth of Izar used to manipulate Captain James Kirk through her beauty as a honeypot.
While Orions were skilled in such tactics, Marta's efforts to seduce Kirk met resistance. In a desperate turn of events, Marta tried to attack Kirk, but her efforts proved futile, resulting in her tragic demise at the hands of Garth.
