The Talosians seek to stimulate an attraction between Captain Christopher Pike (Jeffrey Hunter) and Vina (Susan Oliver) in "The Cage". She was a woman who survived the crash of a spacecraft on Talos IV, and the Talosians had been projecting a series of illusions first to present her as a healthy human, but in order to begin an attraction, first as a princess from the Middle Ages, then as an Orion slave girl, and finally as a personification of Pike's wife. These events are reviewed during a court martial against Spock (Leonard Nimoy) by Captain James T. Kirk (William Shatner) in "The Menagerie". In "Journey to Babel", the Orions attempt to disrupt a Federation conference by inserting an agent disguised as the leader of the Andorian delegation, Thelev (William O'Connell). The agent kills the leader of the Tellarite delegation, Gav (John Wheeler), implicating Ambassador Sarek (Mark Lenard). After the Orion injures Captain Kirk, his ruse is discovered and a pursuing Orion vessel is destroyed. In "", when the USS "Enterprise" arrives at Elba II, a planet containing an underground mental asylum, they find Garth of Izar (Steve Ihnat) impersonating the Governor of the institution. He attempts to use an Orion woman, Marta (Yvonne Craig), to influence the "Enterprise" crew. When this fails, he exiles her to the planet's inhospitable surface, killing her. This episode was the first occasion in the franchise that the appearance of a true Orion was shown.
