On the maiden voyage of the Starship Enterprise, in the unaired pilot ‘The Cage’, Kirk’s predecessor Captain Christopher Pike tries to rescue an Earth crew that disappeared some years earlier. But Pike is imprisoned in a zoo-like cage and studied by the mysterious Talosians who try to understand his reactions to Vina (Susan Oliver) who they present to him in various illusory guises, including that of an Orion slave girl. So Marta (Yvonne Craig) in ‘Whom Gods Destroy’ was the first ‘real’ Orion slave girl to appear in Star Trek.
This footage was recycled into two-part episode ‘The Menagerie’, where Spock takes over the Enterprise to return the now-crippled Pike to Talos IV to enable him to find peace in the company of Vina, who is also deformed in reality. She was the only survivor of the original crash and the Talosians had put her back together as best they could.
In the days before airbrush makeups, Fred B Phillips achieved Vina’s look with hand-applied greasepaint. Besides the need to constantly touch up the makeup, the makeup tests were a trial: as the story is told nobody informed the processing lab that her skin was meant to be turquoise so they kept hand-correcting the colour back to normal skin tones causing some consternation when the footage of the makeup tests came back.
