Rayna 15

From Memory Alpha, the free Star Trek reference

Rayna 15 was an android created by the immortal Flint.

She was a prototype of his later creation, Rayna Kapec and was kept in a sealed laboratory on Flint's planet Holberg 917G. In contrast to the final Rayna Kapec, Rayna 15 had brown hair. (TOS: "Requiem for Methuselah")
