"I am Roger Korby!"
– Korby's android, 2266 ("What Are Little Girls Made Of?")

Dr. Roger Korby was a male android created on the planet Exo III in 2261, who was born with the consciousness of renounced 23rd century archaeologist Roger Korby.

After having his consciousness transferred to this android body, Korby claimed to be the same as an android as he had been as a man, there was evidence that this was not the case; his fiancée, Christine Chapel, was appalled by his callous disregard for the lives of others, and by his plans to selectively introduce android replicas into Federation society.

In 2266, his android body was destroyed when he committed suicide while being kissed by Andrea, leaving open the question of when he had actually died. (TOS: "What Are Little Girls Made Of?")

Roger Korby was played by actor Michael Strong.
When Korby's image was introduced in the script of "What Are Little Girls Made Of?", he was referred to as "an intelligent-looking, but strong-faced man in his late-forties, with a self-assured and commanding presence himself." The cast list called him "Robert Korby", while the rest of the script called him Roger. [1]
