Rayna Kapec was an android built by Flint, an immortal who had wandered the Earth in various personae such as Brahms and Leonardo da Vinci, to be a companion for him.

When the USS Enterprise visited Holberg 917G looking for the cure to a plague that had infected the crew, Flint introduced Rayna as his legal ward. Captain Kirk and Rayna became attracted to each other, which at first Flint was happy about. He hoped that this would provide the final step in her creation, stirring her emotions. Later he became jealous of the relationship.

As Flint and Kirk became involved in a fight over Rayna, her new feelings and the choice between Flint and Kirk overwhelmed her. Rayna, unable to handle such intense emotions, short-circuited and ceased functioning. (TOS: "Requiem for Methuselah")

Background information

Rayna was played by actress Louise Sorel.

Although the signs above the androids clearly read "Rayna", the character was credited in the final credits as "Reena" on the DVD prints. However, the prior VHS and Laserdisc prints spell the name correctly.

According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 402), "Rayna Kapec was named for Czechoslovakian writer Karel Čapek, who first coined the term "robot" in the classic science-fiction play entitled R.U.R.."
