In a parallel universe, Lt. Commander Data was an android who served aboard the USS Enterprise-D during the 24th century. He was created by Dr. Soong more than thirty years earlier, and one of his goals on the Enterprise is to become more human.
Data was present on the ship's holodeck with William Riker and Beverly Crusher when the Doctor's TARDIS materialised in its "Dixon Hill" holonovel in 2368. The Eleventh Doctor noted that the sight of an android wearing a pinstripe suit in San Francisco in 1941 was unusual. (COMIC: Assimilation²)
