|Dr. Pran Tainer (2370)|
|Played by:||William Lithgow|
In 2370, the Tainers discovered that the magma on their homeworld Atrea IV was cooling, which posed a significant threat to the continued habitability of the planet. The starship USS Enterprise-D was sent to assist in finding a solution to this problem. While investigating, Juliana was involved in an accident which revealed that she was, in fact, a Soong-type android constructed by Dr. Noonian Soong, Data's creator. She had been created in the image of the real Juliana Tainer. Pran was unaware of her true nature.
