Data (Assimilation²)

Lt. Commander Data was an android who served aboard the USS Enterprise in the 24th century. He was created by Dr. Soong more than thirty years earlier.

Data was present on the ship's holodeck with William Riker and Beverly Crusher when the Doctor's TARDIS landed in its "Dixon Hill" holonovel. The Eleventh Doctor noted that the sight of an android wearing a pinstripe suit in San Francisco in 1941 was unusual. (IDW: Assimilation²)
